Setiap pola pelayanan tersebut memiliki komponen yang sesuai atau tidak sesuai dengan karakteristik petani. Petani umumnya tidak dapat mengakses lembaga pembiayaan komersial yang menyediakan bunga rendah, seperti BRI Unit Desa, Bank Perkreditan Rakyat, dan koperasi karena tidak memiliki agunan sertifikat tanah, pengembalian kredit bulanan sehingga tidak sesuai dengan pola penerimaan usaha tani yang bersifat musiman, dan prosedur pengajuan kredit yang rumit. Petani juga sulit mengakses Koprasi Unit Desa karena kinerjanya lemah, putaran uang lambat, dan modal sulit berkembang. Petani sulit mengakses kredit program karena kemampuan keuangan Pemerintah yang terbatas. Karena berbagai hambatan tersebut, sebagian petani memilih lembaga pembiayaan informal meskipun dengan tingkat bunga yang tinggi. pola pelayanan kredit yang ideal untuk petani yaitu menghindari penetapan agunan sertifikat tanah, memberikan kredit berbentuk uang tunai, menyediakan kredit jangka pendek dengan pengembalian musiman, jumlah plafon kredit mencukupi untuk membeli benih, pupuk dan obat-obatan, serta pengajuan / penyaluran kredit melalui kelompok tani. disisi lain, petani perlu memahami prinsip penggunaan kredit yang benar, berusaha membangun modal sendiri, dan menciptakan diversiFikasi usaha yang memberikan penerimaan secara harian, mingguan atau musiman.

Index Jurnal Lalat Pengorok Daun, Liriomyza sp. (Diptera:Agromyzidae), Hama Baru Pada Tanaman Kedelai Di Indonesia - Yuliantoro Baliadi dan Wedanimbi Tengkano-JURNAL PENELITIAN DAN PENGEMBANGAN PERTANIAN=Indonesian Agricultural Research and Development Journal GLYCINE MAX, LIRIOMYZA, SIFAT BIOLOGI, PENGENDALIAN HAMA Lalat pengorok daun (Liriomyza sp.) ditemukan menginfestasi tanaman kedelai pada tahun 2007. Larva lalat pengorok daun merusak daun kedelai membuat liang korokan beralur warna putih bening pada bagian mesofil daun dan berpotensi menurunkan hasil hingga 20%. Selain pada kedelai, gejala serangan yang sama juga ditemukan pada kacang hijau, kacang tunggak, kacang panjang, komak, kacang adzuki, buncis, dan 42 jenis tanaman lainnya termasuk gulma. Empat spesies lalat pengorok daun yang di ketahui menginfestasi tanaman kedelai adalah L. sativae, L. trifolii, L. huidobrensis, dan L. bryoniae. Pengendalian kimia dapat menimbulkan masalah karena lalat memiliki kemampuan genetik yang tinggi untuk menjadi tahan terhadap isektisida kimia. Pada habitat aslinya (subtropis), Liriomyza sp. tergolong serangga berstrategi-r, yaitu memiliki kemampuan reproduksi tinggi, cepat mengkoloni habitat, dan kisaran inangnya luas. Habitat tropis dengan ketersediaan tanaman inang sepanjang tahun dan penggunaan insektisida kimia yang kurang bijaksana memungkinkan lalat pengorok daun menjadi hama penting pada kedelai. Pada habitat alaminya, populasi lalat pengorok daun rendah akibat pengendalian alami oleh parasitoid dan predator, salah satunya adalah parasitoid hemiptarsenus varicornis. Oleh karena itu, perlu disiapkan teknologi pengendalian yang lebih memberdayakan peran musuh alami dari pada insektisida kimia. Makalah ini menelaah gejala dan akibat serangan lalat pengorok daun, spesies dan biologi, tanaman inang, musuh alami, pemantauan, dan rekomendasi pengendaliannya.

Index Jurnal Capturing The Benafit Of Monsoonal And Tropical Climate To Enhance National Food Security - Istiqlal Amien And Eleonora Runtunuwu-Jurnal Penelitian Dan Pengembangan Peretanian= Indonesi Agricultural Research And Development Jurnal CLIMATE FARIABLILITY, CLIMATE CHANGE, FOOD SECURITY Altough the consumption level is declining with introved economy and living condition, Rice remains the staple food in many Asian Countries. With annual consumption per capita of more than 100 kg, Indonesia is far higher than Japan, Korea, Taiwan, and Malaysia with around 90 kg but less than the least developed countries in southeast Asia, Laos and Myanmar that consume around 200 kg. Java the most populous island with about 7% of Indonesia terrestrial territory has long been and is still the National rice basket although its countribution for food, water and energy will increase. Consequently food prices will rise, more people will go hungry, and migrants will flee the worst-affected regions. Therefore, to cater the National rice Demand, alternatives has to be found in outer island. The geographic position and variable climate of monsoonal and tropical rainfall patterns as well as the availability of large swathes of swampy land offer opportunity to evenly spread planting time and hence rice production throughout the year. However, recent rapid development of tree plantations will make it difficult to implement without political will supported with strong policy and appropriate planning. This paper describes the challenges and opportunities in utilizing climate variability to enhance national food security and improve farmers' welfare.

Index Jurnal Teknologi Pembibitan Duku Dan Prospek Pengembangannya - Ade Supriatna Dan Suparwoto-Jurnal Penelitian Dan Pengembangan Pertanian= Indonesian Agricultural Research Development Journal PEMBIBITAN, SAMBUNG PUCUK, ANALISIS EKONOMI Kendala utama dalam pengembangan agribisnis duku yaitu belum tersedia dan di gunakannya benih bermutu. Tanaman duku umumnya berasal dari benih asalan. Perbanyakan dengan biji, di satu sisi, memberikan tingkat keberhasilan tinggi. Namun, tanaman memerlukan waktu lama untuk berbuah serta tidak selalu sama dengan induknya. Untuk itu, perlu teknik pembibitan yang lebih baik melalui sambung pucuk. Tulisan ini merupakan tinjauan terhadap pembibitan sambung pucuk pada duku dan prospek pengembangannya, meliputi penyemaian biji untuk batang bawah, pemupukan, persiapan batang atas (entres), cara penyambungan, dan kelayakan usaha pembibitan sambung pucuk. Batang bawah dianjurkan menggunakan jenis lokal karena perakaranya kuat dan daya adaptasinya tinggi terhadap lingkungan. Pupuk NPK diberikan dengan takaran 3 g/tanaman atau manggunakan pupuk daun plant catalyst dengan takaran 2 g/tanaman. Entreas diambil dari pohon induk sehat dan telah berbuah minimal 3-4 kali, produktivitas tinggi, dari ujung cabang yang kulitnya hijau muda dengan posisi tumbuh lurus ke atas. Teknik penyambugannya adalah batang bawah dipotong pada bagian kulit yang masih hijau setinggi 20-25 cm lalu dibelah membujur sepanjang 2-2,50 cm (huruf V). Entres disayat pada kedua sisi sepanjang 2-2,50 cm (huruf V) lalu disisipkan kedalam belahan batang bawah dan diikat tali plastik. Usaha pembibitan duku (skala 5.000 bibit) memberikan pendapatan bersih Rp6.618.560 dengan nilai R/C 2,20. Dengan demikian, teknik sambung pucuk mempunyai prospek yang baik untuk dikembangkan.

Imam Sutrisno, Dan SumarsonoJurnal Penelitian Dan Pengembangan Pertanian= Indonesian Agricultural Research And Development Journal SAPI POTONG,KEBIJAKAN, PENGEMBANGAN, INDONESIA Berbagai upaya telah dilakukan untuk meningkatkan produktivitas, produksi maupun populasi sapi potong dalam rangka mendukung program kecukupan daging (PKD) 2010, yang direvisi 2014. Produksi daging dalam negeri diharapkan mampu memenuhi 90-95% kebutuhan daging nasional. Karena itu pengembangan sapi potong perlu dilakukan melalui pendekatan usaha yang berkelanjutan, didukung dengan industri pakan yang mengoptimalkan pemanfaatan bahan pakan lokal spesifik lokasi melalui pola yang terintegrasi. Hingga kini, upaya pengembangan sapi potong belum mampu memenuhi kebutuhan daging dalam negeri, selain rentan terhadap serangan penyakit. Hal ini dapat disebabkan oleh berbagai kelemahan dalam sistem pengembangan peternakan. Oleh karena itu, perlu diupayakan model pengembangan dan kelembagaan yang tepat berbasis masyarakat dan secara ekonomi menguntungkan. Pemerintah sebaiknya menyerahkan pengembangan peternakan ke depan kepada masyarakat melalui mekanisme pasar bebas. Pemerintah lebih berperan dalam pelayanan dan membangun kawasan untuk memecahkan permasalahan dasar dalam pengembangan peternakan sehingga dapat mengaktifkan mekanisme pasar. Usaha peternakan hendaknya dapat memacu perkembangan agroindustri sehingga membuka kesempatan kerja dan usaha. Implikasi kebijakan dari gagasan ini adalah perlu dibuat peta jalan pembangunan peternakan nasional dan di uraikan secara rinci disetiap wilayah pengembangan ternak.

Index Jurnal Kebijakan Subsidi Pupuk:Ditinjau kembali - Wayan R. Susila-Jurnal Penelitian Dan Pengembangan Pertanian= Indonesian Agricultural Research And Devopment Journal PUPUK, SUBSIDI, ANALISIS KEBIJAKAN Subsidi pupuk yang terus meningkat merupakan salah satu tulang punggung kebijakan pertanian sejak tahun 1969. Berbagai prestasi dibidang pertanian seperti peningkatan produksi dan produktifitas serta swasembada beras, sampai batas tertentu merupakan dampak dari kebijakan subsidi pupuk. Namun, berbagai masalah dan dampak negatif dari kebijakan tersebut, seperti sistem distribusi yang tidak efisien, tidak tepat sasaran, dualisme pasar, penggunaan pupuk yang berlebihan, serta pengembangan industri pupuk yang terhambat, tidak dapat diabaikan. Tulisan ini mencoba meninjau ulang dampak positif dan negatif kebijakan subsidi pupuk. Berdasarkan hasil tinjauan, diusulkan dua pilihan kebijakan. Pilihan pertama adalah melanjutkan kebijakan subsidi pupuk dengan memperbaiki perencanaan, pemantauan, sistem distribusi, dan pemberdayaan penyuluh lapangan. Pilihan kedua adalah mengganti kebijakan subsidi pupuk dengan kebijakan lain yang lebih efektif, seperti subsidi benih unggul, subsidi kredit, perbaikan dan pemeliharaan saluran irigasi, subsidi alat mesin pertanian, perbaikan pemasaran, dan pemberdayaan penyuluh lapangan.

Index Jurnal Peluang Perakitan Dan Pengembangan Kedelai Toleran Genangan - Ratri Tri Hapsari dan M.M. Adie-Jurnal Penelitian Dan Pengembangan Pertanian=Indonesian Agricultural Research And Development Journal PEMULIAAN TANAMAN, GENANGAN, KETAHANAN Sektar 60% produksi kedelai nasional dihasilkan dari lahan sawah. Namun, budidaya kedelai di lahan sawah menghadapi berbagai masalah, antara lain cekaman genangan. Genangan menyebabkan penuaan dini sehingga daun klorosis, nekrosis, dan gugur serta pertumbuhan tanaman terhambat, yang pada akhirnya menurunkan hasil. Umumnya kehilangan hasil pada fase vegetatif lebih kecil dibandingkan pada fase reproduksi, yaitu 17-43% pada fase vagetatif dan 50-56% pada fase reproduktif. Besarnya penurunan hasil tergantung pada varietas kedelai yang ditanam, fase pertumbuhan tanaman, lamanya tergenang, tekstur tanah, dan kehadiran penyakit. Tersedianya varietas kedelai toleran genangan akan memberikan arti penting bagi upaya mempercepat peningkatan produksi kedelai dalam negeri. Pengembangan kedelai toleran genangan tidak hanya bermanfaat dalam tidak hanya bermanfaat dalam pengembangan kedelai dilahan sawah, tetapi juga wilayah yang sering mengalami cekaman genangan seperti lahan pasang surut. Luas lahan pasang surut di Indonesia mencapai 20,10 juta ha, sekitar 2030% di antaranya berpotensi sebagai lahan pertanian. program perakitan varietas kedelai toleran genangan berpeluang di lakukan jika tersedia sumber gen dan metode skrining yang sederhana, mudah, dan cepat. Karakter morfologi dan fisiologi yang dapat secara cepat mendeteksi indikator toleransi kedelai terhadap genangan adalah perkecambahan, tinggi tanaman perubahan warna daun menjadi kuning, kehadiran akar adventif, bobot kering akar, pemutupan stomata, dan kadar N total. Kerjasama dengan lembaga internasional terutama dalam pertukaran sumber gen akan mempertcepat program pemuliaan kedelai toleran genangan

Untuk melindungi produsen dan konsumen pangan dalam negeri, pemerintah menerapkan kebijakan harga komoditas pangan. kebijakan tersebut bertujuan untuk menstabilkan harga pangan, mengurangi ketidakpastian petani, dan menjamin konsumen memperoleh pangan yang cukup dengan harga yang wajar. Rancangan dan implementasi kebijakan harga komoditas pangan nonberas perlu dirumuskan secara komprehensif, yang meliputi: 1) jaminan ketersediaan pangan bagi penduduk miskin dan rawan pangan di seluruh pelosok tanah air, 2) perlindungan terhadap petani melalui implementasi kebijakan harga perlindungan petani (HPP) dan diplomasi perdagangan internasional, dan 3) dialog terbuka antara pemerintah pusat dan daerah untuk mensintesis persepsi dan keinginan daerah terhadap pusat dan sebaliknya.

Index Jurnal Potensi Sapi Pesisir Dan Upaya Pengembangannya Di Sumatera Barat - Adrial-Jurnal penelitian Dan Pengembangan Pertanian= Indonesian Agricultural Research and Development Journal SAPI PESISIR, PENGEMBANGAN, SUMATERA BARAT Sapi pesisir merupakan salah satu jenis sapi lokal Indonesia yang berpoensi sebagai penghasil daging. Walaupun ukuran badannya lebih kecil dibanding sapi lokal lainnya, sapi pesisir memiliki keunggulan yaitu daya adaptasinya tinggi terhadap pakan berkualitas renda, sistem pemeliharaan ekstensif tradisional, dan tahan terhadap beberapa penyakit dan parasit. Sapi pesisir berkontribusi besar terhadap pemenuhan kebutuhan daging bagi masyarakat Sumatera Barat. Populasi sapi pesisir mencapai 20% dari total populasi sapi di Sumatera Barat. Pada tahun 2008, populasi sapi pesisir tercatat 89.995 ekor. Jumlah tersebut jauh menurun dibanding tahun 2004 yang mencapai 104.109 ekor. Penurunan populasi diduga berkaitan dengan sistem pemeliharaan yang berdifat ekstensif tradisional, tingginya tingkat pemotongan ternak produktif, terbatasnya pakan, makin menyempitnya padang penggembalaan, serta terjadinya penurunan genetik. Untuk meningkatkan populasi, produktivitas, dan reproduksi sapi pesisir perlu dilakukan perbaikan kualitas genetik ternak melalui seleksi, persilangan dengan bangsa sapi unggul, perbaikan mutu pakan, penyuluhan kepada peternak agar tidak memotong ternak produktif, dan perbaikan menejemen pemeliharaan.

Index Jurnal Identification of a Major Quantitative Trait locus conferring rice Blast Resistance Using recombinant inbred lines - SobrizalIndonesian Journal Of Agricultural Science:Indonesian Agency for Agricultural Research And Development 1. ORYZA SATIVA 2. PYRICULARIA ORYZAE 3.DISEASE RESISTANCE Blast disease caused by Pyricularia oryzae is one of the limiting factors for rice production world wide. The use of resistant varieties for managing blast disease is considered as the most eco-friendly approcoaches. However, their resistances may be broken down within a few years due to the appearance of new virulent blast races in the field. The objective of the present study was to identify the qinbreuantitative trait locus (QTL) confering resistance to blast disease using 126 recombinant inbred (RI) lines originated from a crossing of a durably resistant upland rice genotype (Laka) and a highly susceptible rice accession cultivar (Kencana Bali). The RI population was developed through a single seed descent method from 1997 to 2004. Resistance of the RI lines was evaluated for blast in an endemic area of Sukabumi, West Java, in 2005 . Disease intensity of the blast was examined following the standard evaluation system developed by the Internasional Rice Research Institute (IRRI). At the same year the RI lines were analyzed with 134 DNA markers. Result of the study showed that one major QTL was found to be associated with blast resistance, and this QTL was located near RM2136 marker on the long arm of chromosome 11. This QTL explained 87% of the phenotypic variation with 37% additive effect. The map position of this QTL differed from that of a partial resistant gene, Pi34, identified previosly on chromosome 11 in the Japanese durably resistant variety, Chubu 32. The QTL, however, was almost at the same position as that of the multiple allele-resistance gene, Pik. Therefore, an allelic test should be conducted to clarify the allelic relationship between QTL identified in this study and the Pik. The RI lines are the permanent segregating population that could be very useful for analysing phenotypic variations of important agronomic traits possibly owned by the RI lines. The major QTL identified in this study could be used as a genetic resource in improvement of rice varieties for blast resistance in Indonesia.

Index Jurnal Correlation Analysis Of Agronomic Characters And Grain Yield Of Rice For Tidal Swamp Areas - Aris Hairmansis-Indonesian Journal Of Agricultural Science:Indonesian Agency for Agricultural Research And Development 1. ORYZA SATIVA 2. AGRONOMIC CHARACTERS 3. PATH ANALYSIS Development of rice varieties for tidal swamp areas is emphasized on the improvement of rice yield potential in spesific environment. However, grain yield is a complex trait and highly dependent on the other agronomic characters; while information related to the relationship between agronomic characters and grain yield in the breeding program particularly for tidal swamp areas is very limited. The objective of this study was to investigate relationship between agronomic characters and grain yield of rice as a basis for selection of high yielding rice varieties fortidal swamp areas. Agronomic characters and grain yield of nine advanced rice breeding lines and two rice varieties were evaluated in a series of experiments in tidal swamp areas. Karang Agung Ulu Village, Banyuasin, South Sumatra, for four cropping seasons in dry season (DS) 2005, wet season (WS) 2005/2006, and DS 2007. Result from path analysis revealed that the following characters had positive direct effect on grain yield, i.e. number of productive tillers per hill (p=0.356), number of filled grains per panicle (p=0.544), and spikelet fertility (p=0.215). Plant height had negative direct effect (p=-0.332) on grain yield, while maturity, number of spikelets per panicle, and 1000-grain weight showed negligible effect on rice grain yield. Present study suggests that indirect selection of high yielding tidal swamp rice can be done by selecting breeding lines which have many produtive tillers, dense filled grains, and high spikelet fertility.

Index Jurnal Protoplast Fusion Between White And brown Oyster Mushrooms - Ira djajanegara-Indonesian Journal Of Agricultural Science:Indonesian Agency for Agricultural Research And Development 1.PLEUROTUS FLORIDAE 2.PLEUROTUS CYSTIDIOSUS 3.PROTOPLAST FUSION Genetic crossing of white oyster mushroom(Pleurotus floridae) to introduce longer storage life trait can only be done within individuals in this particular species. However, longer storage life trait is possessed by brown oyster mushroom(Pleurotus cystidious). Therefore, a protoplast fusion experiment between white brown oyster mushrooms was conducted to obatain an oyster mushroom strain showinghigh productivity and long storage ife. the experiment was done at the biology laboratory of the University of AlAzhar Indonesia from May 2008 to August 2009. Protoplast fusion was done by isolating protoplast from 5-day old monokaryotic mycelia grown in potato dextrose broth (PDB). Around 3.15 x 105 protoplasts ml-1 were harvested using mixture of cellulase Onozuka R-10 (1%) and macrozyme R-10 (1%) from brown oyster mushroom with 80.61% viability.similarly, 3.71x105 protoplasts ml-1 were harvested using lysing enzyme (2%) from white oyster mushroom with 83.68% via-bility. protoplast fusions were condutected using 40% PEG 6000 for 10 minutes. the candidate fusants were then screened using minimum regeration media (MRM). there were 22 colonies grew on MRM media and four colonies (FS1, FS2, FS3, and FS4) showed clamp connection as well as primordia formation to be chosen as candidate fusants. however, isozyme studies using malate dehydrogenase and acid phosphatase as marker enzymes confirmed that only FS1 and FS2 were the hybridized products. the two colonies showed different mycelia growth patterns and hyphae sizes,fruit body morphology and productivity compared to their parents. These two fusants, however, did not indicate the presence of longer strorage life trait as expected despite a higher productivity achieved by FSI. In this study, the protoplast fusion only yielded higher productifity strain of mushroom with different colors without any changes in storage life.

ORIZA SATIVA 2. GENOTYPES 3. SEASONAL ADAPTATION Rice planting on dry and wet season faces a specific climatological characteristic, which affects directly on rice growth and yield. Fifteen rice genotypes were evaluated for their seasonal planting adaptation at Sukamandi Experimental Station, Subang, West Java, during the dry and wet seasons of 2009-2010. Randomized complete block design with three replication was applied on the experiment. Plot size was 4 m x 6 m and plant spacing was 20 cm x 20 cm. Standart agronomic practices were applied on both planting season experiments. Data were collected for major morphological traits, days to grain maturity and grain yield, measured on wet and dry basis (11% moisture content). Data were analyzed for analyses of variance for each season and for combined seasons, and mean values separation of the variable used the 5% Duncan Multiple Range Test. Correlation between grain yields and morphological variable data were computed for each season and for combined season. The correlation coefficients of variables and grain yield were partitioned into direct and indirect causes using path analyses. Combined analyses of veriances indicated significant effects of genotypes, season and genotypes x season interaction for almost all variables, including grain yields, suggesting there were seasonal adaption specificity among genotypes. Five genotypes were identified as suitable for dry season planting, and nine genotypes as suitable for wet season planting. Among those getypes, there genotypes, namels mekongga, inprari-10 and OM 5240 were suitable for both dry and wet season plating. ciherang and cigeulis varieties were more suitable for dry season, whele cibogo, inpari-1, inpari-3, inpari-5, and inpari-8 were more suitable for wet season plating. adopting the most productive rice varieties for plating on dry or wet season as was suggested on this research should increase rice production substantially. to facilitate the availability of varieties adapted for a specific plating season, rice breeding should purposedly apply a directional selection of lines suitable for specific plating season, starting on the early generation of selection.

Index Jurnal Land use change and recommendation for sustainable development of peatland for agriculture : case study at Kubu Raya and Pontianak districts, West Kalimantan - Wahyunto, Wahyu Supriatna, Fahmuddin Agus-Indonesian Journal Of Agricultural Science:Indonesian Agency for Agricultural Research And Development 1. PEATLANDS 2. LAND USE 3. AGRICULTURAL DEVELOPMENT Peatland is an increasingly important land resource for livelihood, economic development, and terrestrial carbon storage.Kubu Raya and Pontianak Districts of West Kalimantan rely their future agricultural development on this environmentally fragile peatland because of the dominance (58% and 16% area, respectively) of this land in the twodistricts. A study aimed to evaluate land use changes on peatland and to develop strategies for sustainable peatland use and management for agriculture. Time series satellite imageries of land use and land cover, ground trithing, and statistical data of land use change were analyzed for generating the dynamics of land use changes in the period of 1986-2008. Field observation, peat sampling, and peat analyses of representative land use types were undertaken to assess peat characteristics and its agricultural suitability. The study showed that within 22 years(1986-2008), the area of peat forests in Kubu Raya and Pontianak Districts decreased as much as 13.6% from 391,902 ha to 328,078 ha. The current uses of the peatland in the two districts include oil palm plantation(8704 ha), smallholder rubber plantation(13,186 ha), annual crops (15,035 ha), mixed cropping of trees an annual crops (22,328 ha), and pineapple farming (11,744 ha). Our evaluation showed unconformity of the current uses of peatland with regulations and crops agronomic requirementssuch as peat thickness and maturity, rendereng unsustainability.This study recommends that expansion on peatland areas be limited over idle land within the agricultural prodution and corversion production forest areas.About 34,362 ha (9,7%) of uncultivated log-over forest and shrubs can potentially be develoved for conservation or forest protection due to low inherent soil fertility and higt potential greenhouse gas emissions if converted for agriculture.

Index Jurnal Control Of Cocoa Pod Borer And Phytophthora Pod Rot Using Degradable Plastic Pod Sleeves And A Nematode: Steinernema Carpocapsae - Ade Rosmana-Indonesian Journal Of Agricultural Science: Indonesian Agency For Agricultural Research and Development 1. THEOBROMA CACAO 2. CONOPOMORPHA CRAMERELLA 3. STEINERNEMA CARPOCAPSAE Cocoa pod borer (CPB; Conopomorpha cramerella) and phytophthora pod rot (PPR; Phytophthora palmivora) are serious pest and disease on cocoa plantations in Indonesia. Both pest and disease have been controlled with limited success using cultural practices such as pruning, frequent harvesting, sanitation, plastic sleeving, and chemical pesticides. An experiment was conducted on cocoa plantings in Pinrang Regency, south Sulawesi during the wet season of 2008/09 to test the effect of pod sleeving (with transparent degradable and non-degradable plastic bags) and nematode application on CPB and PPR infestation. The nematode, Steinernema carpocapsae (10,000 active juveniles per pod) was sprayed three times at intervals of 10 and 20 days. Pod damage by CPB was observed at harvest time, while PPR disease incidence was evaluated every week until harvest time. Results showed that all pods in the field were infested by CPB as indicated in control samples. Pod sleeving using both non-degradable an degradable plastics significantly reduced pod damage by CPB, from 62.3% in the control treatment compared to 8.4% in the CPB treatment. A combination of pod sleeving and nematode applications had a synergistic reduction of pod damage by CPB resulting in totally healthy pods. Pod sleeving with degradable and non-degradable plastics also reduced pod damage by PPR significantly. Pod sleeving with non-degradable plastic suppresed the disease incidence almost zero until 6 weeks after sleeving and the rate of disease incidence was 3.6% per week. However, with degradable plastic, the disease suppression was even longer (7 weeks after sleeving), indicating that the degradable plastic is more effective. Combination of sleeving and nematode application slightly increased PPR infection. Sleeved pods treated with nematode or untreated pods (control). In these two applications, the rate of disease incidence wash 7.8% and 8.3% per week respectively. The study implies that biological control using entomopathogenic S. carpocapsae and degradable plastic sleeves are effective and environmentally-friendly to control C. cramerella and P. palmivora on cocoa.

Index Jurnal Identification of Lead and Cadmium levels in white Cabbage (Brassica rapa L.) soil and Irriagtion Water of Urban Agricultural Sites in the Philippines - Hardiyanto-Indonesian Journal Agricultural Science: Indenesian Agency for Agricultural Research and Development 1. BRASSICA RAPA 2. URBAN AGRICULTURAL Urban agriculture comprises a variety of farming systems, ranging from subsistence to fully commercialized agriculture. Pollution from automobile exhaust, industrial and commercial activities may affect humans, corps, soil, and water in and around urban agriculture areas. The research aimed to invetigate the level and distribution of lead (Pb) and cadmium (Cd) in white cabbage (Brassica rapa L.), soil, and irrigation water taken from urban sites. the research was conducted in las pinas and parañaque, Metro Manila, Philippines. The field area was divided into three sections based on its distance from the main road (0, 25, and 50 m).Irrigation water was taken from canal (Las Piñas) and river (Parañaque). Pb and Cd contents of the extract were measured by Atomic Absorption Spectrophotometry. Combined analysis over locations was used. The ralationship between distance from the main road and metal contents was measured by Pearson's correlation. Based on combined analyses, highly significant difference over locations was only showed on Cd content in white cabbage. Cd content in white cabbage grown in Parañaque was higher than that cultivated in Las Piñas, while Cd content in the soil between both sites was comparable. The averge Pb content (1.09 µg g-1 dry weight) was highest in the white cabbge grown right beside the main road. A similar trend was also observed in the soil, with the highest concentration being recorded at 26 µg g-1 dry weight. There was a negative relationship between distance from the main road and Pb and Cd contents in white cabbge and the soil. Level of Pb in water taken from the canal and river was similar (0.12 mg I-1 ), whereas levels of Cd were 0.0084 and 0.0095 mg I-1 , respectively. in general, the concentratios of Pb and Cd in the cabbage and soil as well as irigation water were still in the accetable limits. In terms of environmental hazards and polluted city enviroment, it seems that big cities in Indonesia especially Jakarta and Surabaya have the same problem with the Philippines. Therefore, it is suggested that the study on heavy metal contaminatoin in several crops, especially those grown along the main road, should be conducted.

Index Jurnal Assessing global climate variability under coldest and warmest periods at different latitudinal regions - Eleonora runtunuwa-Indonesian Journal Agricultural Science: Indenesian Agency for Agricultural Research and Development 1.climate change 2.air temperature Effect of climate change on water balance will play a key role in the biosphere system. To study the global climate change impact on water balance during 95-year period (1901-1995), long-tern grid climatic data including global mean monthly temperature and precipitation at 0.5 x 0.5 degree resolution were analysed. The trend and variation of climate change, the time series of monthly air temperature and precipitation data were aggregated in to annual arithmetic means for two extreme periods (1901-1920 and 1990-1995). The potential evapotranspiration (Eo) was calculated using Thornthwaite method. The changes in mean annuan value were obtained by subtractieng the maximum period data from 1990 to 1995 (Max) with the minimum period data from 1901 to 1920 (Min). the results revealed that over 95-year period, mean global air temperature increased by 0.57°C. The temperature increase varied greatly in Asia, with more than 3.0°C, espcially at 45-70°N, as well over the northern part of America (60-65°N) and Europe (55-75°N). In low latitud across Asia, Arfica, and South America, the variation was less than 1.5°C. In 80-85°N region, the variation was relatovely small and at higher latitudes it increased significantly. Presification varied temporally and spatially. In the 40-45°N and 40-45°S regions, increasing precipitation of more than 100 mm uccurred during the June-August and September-November, espicially in the northern hemisphere. The Eo increase of 2000 mm during 95 years occurred in the tropical northen America, middle Africa, and south-East Asia A grid in Central Java of Indonesia showed that the Eo increase of 2500 mm during 95 years resulted in the decrease of growing period by 100 days . In coping with climate change adjustemt of cropping calender is inperative.

Index Jurnal Application of fruit bagging, sanitation, and yellow sticky trap to control thrips on mangosteen - Affandi , D-Indonesian Journal Agricultural Science: Indenesian Agency for Agricultural Research and Development 1.mangosteen 2.thrips Scars on mangosteen fruits coused by thrips are the most prominent constraint in Indonesian export of mangosteen. Most of the exported mangosteed are rejected due to scar appearance. This research aimed to study the effects of fruit bagging, sanitation, and sticky trap application on the scars intensity on mangosteen the research was conducted at a farmer's polycultured mangosteen orchard in Lima Puluh Kota, West Sumatra, Indonesia from September 2006 to February 2007. The mangosteen trees were cultured with cacao and coconut. To study the effect of bagging on the number of scars, the fruits were individually bagged at different time points starting from the time of calyx falling down (0) followed at 2, 4, 6, 8, 10, 12, and 14 weeks later. Each treatment was replicated six times. The experiment of sanitation (SNT) and yellow flourescent sticky trap (YST) application was designed in completely randomized designed with six replications, except for the control which was replicated only three times. Four treatments studied were SNT, YST, combination of SNT+YST, and control. The sanitation was applied by removing all weeds under the canopy of mangosteen trees followed with soil tillage and fogging. The sticky trap was nailed on woody stickes and placed on 3m above the ground at four different positions around the tree canopy. Parameters observed were the percentage and intensity of scars and number of thrips caught on the sticky traps. The results showed that application of early bagging, SNT, TST, and SNT+YST were effective to reduce intensity and percentage of scars. However, combination of SNT+YST demonstrated the best result in reducing the intensity and percetage of scars by 32.14% and 42.82%, respectively. Combination of SNT+YST also drestically decreased thrips population as indicated by the low number of thrips catched after five biweekly observation. Since the fifth observation, the thrips population was low (less than 5 thrips catched per sticky trap) and far below the economic threshold. The present study implies the importance of early fruit bagging, sanitation, and sticky trap application in protecting mangosteen fruits from scars.

Index Jurnal Combining Effects of Cultural Practices and resistant Cultivars on Reducing The Incidence of Meloidogyne spp. and:thrips palmi Karny on Potato - Wiwin Setiawati-Indonesian Journal of Agricultural Science:Indonesian agency for Agricultural Research and Development 1. POTATO 2. MELOIDOGYNE SPP. 3. THRIPS PALMI 4. TAGETES ERECTA Root-knot nematode (Meloidogyne spp.) and melon Thrips ( Thrips palmy Karny)are two serious pests on potato. These pests are conventionally controlled with syntetic pesticides. Cultural practices based on integrated pests management (IPM) are alternative methods to control these pests. The study aimed to determine the effectiveness of combined application of cultural practise and potato cultivars in reducing in incidence of nematode and thrips.Treatments evaluated were methods of nematode and thrips control by implementing IPM and conventional practices. A split-plot randomized complete block design with four replications was used. The main plots were IPM or cultural practices( subsoiling, soil solarization and use of trap crop of marigold tagetes erecta) and conventional practices using synthetic pesticides. The subplots were five potato cultivars, i.e. No.095 (Herta x FLS17),720050/Kikondo,676068/1.1085, Granola, and Atlantic. The results showed that applications of cultural practices in combination with potato cultivars reduced Meloidogyne spp. population and potato tuber damage by 53.70% and 61.36%,respectively, as well as a significantly decreased thrips population. In the cultural control plots, thrips populations were below the action threshold ( 10.0 nymphs per leaf), therefore no single application of pesticide was used. This was in contrast to the conventional control treatments where insecticide was spayed 10 times until harvest. The subsoiling and solarization cut off the life cycle of the thrips and any survive thrips were trapped by marigold plant. Population of T.palmi on the five potato cultivars differed significantly;the lowest population was found on the cultivars No. 095 (Herta x FLS-17) and 676068/1.1085. The cultural control practices combined with potato cultivars No. 095 (Herta x FLS-17) were the best treatment for controling Meloidogyne spp.and T. palmi on potato and also produced the highest yield (31.01 t ha–¹). The study suggests that cultural control practices in combination with resistant cultivars are recommended as a suitable IPM to control nematode and thrips on potato crops.

ORYZA SATIVA 2. TRANSGENIC PLANT 3. GENETIC RESISTANCE Succesful application of genetic transformation technique, especially in developing rice variety resistant to brown plant hopper and stem borer, will depend on transgene being expressed and the gene inherited in a stable and predictable manner. This study aimed to analyse transgene segregation pattern of the progenis and the crosses of transgenic rice cv. Rojolele harboring cry 1Ab and gna genes. The third generation (T2) of five transgenic rojolele events containing gna and/or cry1Ab were evaluated for two generations to identify the homozygous lines and to study their inheritance. The homozygous lines were selected based on the result of PCR technique.The segregation patterns of gna and cry1Ab were studied in eight F2 populations derived from Rojolele x transgenic Rojolele homozygous for cry1Ab and or gna and their reciprocal crosses. Data resilted from PCR of F2 population were analysed using a Chi Square test. The study obtained six homozygous lines for gna , namely A22-1-32, A22-1-37, C72-1-9, F11-1-48, K21-1-39, K21-1-48, and two homozygous lines for cry1Ab, namely K21-1-39 and K21-1-48. Both cry1Ab and gna transgenes had been inherited through teh selfing and crossing with their wild type as indicated from the F1 containing gna and cry1Ab as many as 48.4% and 47.4%, respectively. In six of the eight crosses , gna was inherited in a 3:1 ratio consistent with Mendelian inheritance of a single dominant locus , while in the remaining two crosses, gna was segregated in a 1:1 ratio. The presence of cry1Ab in F2 population also showed a 3:1 segregation ratio in all crosses. In the F2 population derived from F1 plant containing cry1Ab and gna, both transgenes segregated in a 9:3:3:1 dihybrid segregration ratio. This study will add to the diversity of genetic sources for insect resistence and allow further use ot these transgenic lines for pyramiding resistence to brown palnt hopper and stem borer or separately in rice breeding programs whenever the efficacy tests and biosafety requirenments have been completed.

The farming is not only important for sustainable livelihood, but also for superior environmental protection. During the tsunami, considerable portion of thi 'green infrastructure' was devastated. Therevore, a scientifically based land suitability evaluation is needed for supporting the redesign and recontruction of the tree-based farming.The objectives of this research were to evaluate the current physical condition of the area and develop recommendation of land suitability vor tree crops farming in the area. Fieled survey for invetory and evalution of land characteristics was conducted in 2006, 15 months after the tsunami. Land suitability evaluation was conducted by matching field survey data and soil sample analyses in every mapping unit with crop growth requirements. The land suitability map was further matched with the district development plan, existing land uses and land status.The resulted land use recommendation map showed that the marine ecisystem along the coastal line was mostv suitable for coconut, cacao, coffe and casuarinas. the recommended tree crops for the ancient sandy beach were areca nut, coconut, rambutan, mangom rubber and oil palm; and for the alluvial ecosystem were coconut, cacao, areca nut, mango and bread fruit. Peatland of less than 3 m thick was marginally suitable for oil palm anf rubber ,while those thicker than 3 m were recommended for conservation due to its fragile ecosystem. In the undulating tectonic plain, the suitable tre crops were rubber, oil palm, coconut, and rambutan.

Index Jurnal Identification and Mapping of a Gene for Rice Slender Kernel Using Oryza glumepatula Introgression Lines - Sobrizal-Indonesian Journal Agricultural Science: Indenesian Agency for Agricultural Research and Development 1. GENTIC MAPS - ORYZA GLUMAEPATULA 2. GRAIN QUALITY Abstract : World demand for superior rice grain quality tends to increase. One of the criteria of appearance quality of rice grain is grain shape. Rice consumers exhibit wide preferences for grain shape, but most Indonesian rice consumers prefer long and slender grain. The objectives of this study ware to identify and map a gene for rice slender trait using Oryza glumaepatula introgression lines with O. Sativa cv. Taichung 65 genetic background. A segregation analysis of BC4F2 population derived from backcrosses of a donor parent Oryza glumaepatula into a recurrent parent Taichung 65 showed that the slender kernel was controlled by a single recessive gene. This new identified gene wes designated as skl (slender kernel 1). Moreover, based on the RFLP analyses using 14 RFLP markers located on chromosomes 2, 8, 9, and 10 in which the Oryza glumaepatula chromosomal segments were retained in BC4F2 population , the skl was locatecbetween RFLP markers C676 and C560 on the long arm of chromosome 2, with map distances of 2.8 and 1.5 cM, repectively. The wild rice Oryza glumaepatula carried a recessive allele for slender kernel. This allele may be useful in breeding of rice with slender kernel types. In addition, the development of plant materials and RFLP map associated with slender kernel in this study is the preliminary works in the effort to isolate this importantgrain shape gene.

Index Jurnal Role of Polyamines in Inhibition of Ethylene Biosynthesis and Their Effects on Rice Anther Culture Development - Iswari S. Dewi-Indonesian Journal Agricultural Science: Indenesian Agency for Agricultural Research and Development 1. ANTHER CULTURE 2. ORYZA SATIVA Abstract : The polyamines such as putrescine, spermidine, ware reported to increse green plant regeneration in rice anther culture. Low respone of anther culture of rice sub-spicies indica may be improved with the addition of putrescine in the culture media. Four experiments ware conducted to study the role of polymines in inhibition of ethylene biosynthesis and their effects on rice anther culture development. Anthers oftwo subspecies of rice, indica (IR64, Krowal, Jatiluhur) and japonica (Taipei 309) ware cultured onto media supplemented with putrescine (N6P) and without putrescine (N6). Young panicles containing the anthers at mid-to-late nucleate microspores ware cold pretreated at 5 + 2o C and incubated in the dark for 8 days before the anthers were cultured. Resultsshowed that medium without putrescine produced an earlier senesence of indica rice anther than that japonica. The adition of 10-3 M putrescine into the culture mdeia inhabited ethylene biosynthesis as anther senescence delayed, increased the three polymines contents, and decreased the ACC content as well as ACC oxydase activity in anther-derived calli. In the anther and anther-derived calli of subspecies indica, the total polymines content was lower (10.14 nM g-1 anther and 8.48 nM g-1 calli) than that of subspecies japonica (12.61 nM g-1 anther and 10.16 nM g-1 calli), whereas the ethylene production was higher (32.31 nM g-1 anther and 2.48 nM g-1 calli) than the japonica (31,68 nM g-1 anther and 1.76 g-1 calli). This study suggest that application of 10-3 M putrescine in anther culture of rice subspecies indica improves androgenesis by inhabiting early senescence of cultured anthers and enhaching embryo or callus formation from micospores.

Index Jurnal Mycotoxin Contamination on Corn Used by Feed Mills in Indonesia - Budi Tangendjaja-Indonesian Journal Agricultural Science: Indenesian Agency for Agricultural Research and Development 1. ANIMAL FEED - CORN 2. MYCOTOXIN Abstract : Mycotoxin which are secondary metabolites of fungi contaminate agricultural products such as corn and have deleterious effects on human and animal. The obejctive of this study was to evaluate the mycotoxin contamination on local and imported corn samples collected from differnt feed mills in Indonesia. Three hundred fifty six of corn samples ( 0.50 kg each) were sent by several feed mills to Indonesian Resarch Institute for Animal Production during 2005-2006. The background information acoompanied with each sample was country/province of origins, harvesting seasons, postharvest drying methods, moisure levels, grades, and varieties. The samples were analyzed for various mycotoxins, i. e aflatoxin (AFL), ocgratoxin (OCRA), zearalenone (ZEN), fumonisin (FUM), deoxynivalenol (DON), and T2 toxin using commercial kits, except for AFL which is analysed uding kit develop by the Indonesian Research Center for Veterinary Science. The results showed thataverage AFL level in the contaminated corn originated from Indonesian was 59 µg kg-1 , almost 7 times higer than that imported from the USA or Argentina. Among the types of mycotoxins detected, FUM was the highest with an average of 1193 µg kg-1 , followed by DON, ZEN and OCRA at level of 324, 22 and 2 µg kg-1 , respectively. Mycotoxin levels in the contaminated local corn samples variated depending on the province of origins as well as harvesting seasons, postharvest drying methods, and moisture contents. The last mycotoxin contaminations ware found on corn originated from North Sumatra and Lampung with AFL levels ware < 20 and < 50 µg kg-1 , respectively, lower than those from East Java, Central Java and South Sulawesi (64-87 µg kg-1 ). Mycotoxin levels, however, ware less affected by grading made by feed mills and corn varieties. It is indicated that AFL was the most important mycotoxin as far as animal feeding concerned, as it contaminated almost 50% of local corn with the level of contamination above the Indonesian National Standart, i.e 50 µg kg-1. The study suggests postharvest methods of local corn must be improved to reduce mycotoxin contamination.

GENOTYPE X ENVIRONMENT INTERACTION 2. AMMI MODEL 3. MANIHOT ESCULENTA Abstract : Cassava (Manihot Esculenta) is planted in dry area with different enviromental conditions, therefore the yield is varied. The aim of the study was to anlyze the genotype x environment interactions for starch yield in 9-month old cassava promising clones. The experiment was conducted on mineral soil in four differnt locations, i.e Lumajang-East Java (Inceotisols), Kediri-East Java (Entisols), Pati-Central Java (Alfisols), amh tulungbawang-Lampung (Utisols) during 2014-2005. The experiment was arranged in split plot design with threereplications. The main plots ware cultivation techniques, i.e. simple technology and improved technology, whereas the subplots ware 15 cassava promising clones. starch yieldof 9month old cassava plant was analyzed using the additive main effect and multiplicative interaction (AMMI). The result showed that environmental factors detrmined the stability of starch yield were soil bulk density on suboil, the number of rainy days at fifth month, minimum air tempeature at fourth month, and minimum air humidity at seventh month.CMM97002-183, Adira 4, CMM97007-145, CMM97007-235, Malang 2, CMM97002-36 and CMM97006-44 ware identified as the stable cassava clones for starch yield in 9-month old. Average starch yield in 9-month old. Average starch of Adira 4 was the third after MLG 10311 and CMM97006-52. The CMM97006-52 was adopted to the soils hacing P2 O 5 content on topsoil, high minimum air, temperature at 4 and 5 months after planting, high mini-mum relative humidoty at 7 months after planting, low total rainfall at 5 months after planning, and low number of rainy days at 5 and 8 months after planting. MLG 10311 was adapted to low soil bulk density. The average starch yield of MLG 10311 was the highest at 9 months after planting. The study implies that advenced trials for CMM 977006-52 and MLG 10311 clones are needed, so the clones can be relased as new varieties of cassava. In selection and evaluation, the bulk density on suboil is needed to be attained specificallz to incrase the probability to obtain variety of cassava.

Index Jurnal Soybean Seedling Root Growth Promotion by 1-Aminocyclopropane-1-Carboxylate Deaminase-Producing Pseudomonads - Edi Husen-Indonesian Journal Agricultural Science: Indenesian Agency for Agricultural Research and Development 1. ROOT DEVELOPMENT - SOYBEAN 2. ACC DEAMINASE Abstrak : Pseudomonad producing 1-aminocyclopropane-1-carboxylate (ACC) deaminase (E.C.4.1.99.4) has been known to promote plant growth by lowering ethylene biosynthesis in higher plants, which can be induced by indole-3-acetic acid (IAA) production. The objective of this study was to examine the ability of IAA-producing Pseudomonas isolated from local soil environment (rizhosphere of soybeans grown in Plumbon's agricultural area in Cirebon, West Java, Indonesia) to promote soybean root growth in relation on their ACC deaminase activities. The experiments were conducted in growth room and Laboratory of soil Biology Research, Indonesia Soil Research Institute, Bogor, from Januaryto August 2008. Soybean seeds were inoculated by immersing the seeds for 1 hour in bacterial cell suspension containing approximately 108 -109 cells ml-1 . The seed were then germinated for 2 days before planting in growth pouches containing sterilized distilled water. All treated and untreated seeds were grown for 7 days in growth room at 24°C with 1300 lux of light intensity for 12-hour followed by a 12-hour dark period at 22°C. ACC deaminase activity of the isolates was assayed based on their abilty to grow in Dworkin-Foster's salt minimal medium containing ammonium sulfate or ACC as a source of nitrogen. Thirteen out of 81 isolates tested significantly increased soybean root length and weight, up to 50% from untreated plants. Of 13 isolates, 11 demonstrated ACC deaminase activities. Two isolates that did not show ACC deaminase activities had lower capacity to produce IAA. The result suggest that the effectiveness of IAA-producing Pseudomonas in promoting growth of the soybean seedlings is associated with their ACC deaminase activities or they produce IAA at low levels.

Index Jurnal The Continual Forming and Contribution of Infective Juveniles Produced Via Endotokia matricida of Entomopathogenic Nematodes in the Family of Steinernematidae and Heterorhabditidae - Yuliantoro Baliadi-Indonesian Journal Agricultural Science: Indenesian Agency for Agricultural Research and Development 1. ENTOMOPHILIC NEMATODES 2. INFECTIVE JUVENILES Abstract : The non-feeding developmentally arrested infective juveniles (IJs) of entomopathogenic nematodes in family of Steinernematidae and Heterorhabditidae seek out a susceptible insect host and initiate infections. The aim of the research was to examine the continual forming and contribution of IJs produced via endotokia matricida (IJs-EM) of Heterorhabditis bacteriophora, Steinernematidae glaseri, and S. carpocapsae. The research was conducted at the Laboratory of Nametology of the Saga University, Japan (April 2001-April 2002) and the Laboratory of Nematology of the Indonesian Legune and Tuber Crops Research Institute (June 2003-October 2004). The nematode progenies were investigated using greater wax moth, Galleria mellonella, pre-inoculated with 50 IJs at 25°C. Results showed that three reproductive adult generatian were observed at day 18th . There were 135,000, 128,000 and 133,000 IJs per insect cadaver produced in H. bacteriophora, S. glaseri and S. carpocapsae, respectively. Endotokia matricida contributed a higher number of IJs than that of normal mode of IJs production. The rations are 81%, 28% and 64% for H. bacteriophora, s. glaseri, and s. carpocapsae of the IJs total production,respectively. Among the generations, the highest contribution of IJs was come from the third adult generation bearing endotokia matricida, i.e., 63%, 24% and 51% for the three nemotode species. Although the IJs-EM ware more transparent compared to normal IJs, they were morphologicaly similiar. The results show that endotokia matricida has pivotal role in a species maintenance and survival strategy of entomopathogenic nematodes in extreme enviromental conditions.

Index Jurnal Kinetic Evaluation of Ethanol-Tolerant Thermophile Geobacillus thermoglucosidasius M10EXG for Ethanol-Production - Eny Ida Riyanti-Indonesian Journal Agricultural Science: Indenesian Agency for Agricultural Research and Development 1. KINETIC PARAMETERS 2. ETHANOL Abstract : Thermophilies are challenging to be studied for ethanol production using agricultural waste containing lignocellulosic material rich in hexose and pentose. These bacteria have many advantages such as utilizing a wide range of substrates, including pentose (C5) and hexose (C6). In ethanol production, it is important to use ethanol tolerant strain capable in converting lignocellulosic hydrolysate. This study was aimed to investigate the growth profile of ethanol-tolerant thermophile Geobacillus thermoglucosidasius M10EXG using a defined growth medium consisted of single carbon glucose (TGTV), xylose (TXTV), and a mixture of glucose and xylose (TGXTV), together with the effect of yeast extract addition to the media. The experiments were conducted at the School of Biotechnology and Biomolucelular Sciences of The University of New South Weles, Australia on a shake flask fermentation at 60°C in duplicate experiment. Cultures were sampled every two hours and analised for their kinetic parameters including the maximum specific growth rate (µmax ), biomass yield (Yx/s), ethanol and by-product yields (acetate and L-lactate) (Yp/s), and the doubling time (Td ). Results showed this strain was capable of growing on minimal medium containing glucose or xylose as a single carbon source. This strain utilized glucose and xylose simultaneously (co-fermentation), although there was glucose repression of xylose at relatively low glucose concentration (0.5% w/v), particulary when yeast extract (0.2% w/v) was added to the medium. The highest biomas yield was obatained at 0.5 g 1-1 on glucose medium; the yield increased when yeast extract was added (at 0.59 g 1-1 ). The highest specific growth rate of 0.25 was obatained in the phase I growth when sttrain was grown on a mixture of glucose an xylose (0.5% : 0.5% w/v) medium. Diauxic growth was shown on the mixture of glucose, xylose, and yeast extract. The strain product low level of ethanol (0.1 g 1-1 ), as well as low level (0.2 g 1-1 ) of by products (L-lactate and acetate) after 15 hours. The result suggests its potential application for fermenting lignocellulosic agricultural wastes for ethanol production.

Index Jurnal Methane Emission from Direct Seeded Rice Under the Influences of Rice Straw and Nitrificator Inhibitor - A. Wihardjaka-Indonesian Journal Agricultural Science: Indenesian Agency for Agricultural Research and Development 1. NITRIFICATION INHIBITOR 2. DIRECT SEEDED RICE Abstract : Incorporation of rice straw into soil is a common practice to improve soil productivity and increase inorganic fertilizer availability. However, this practice could contribute to methane (CH 4 ) emission; one of the greenhouses gases that causes global warming. Nitrification inhibitors such as neem cake and carbofuran may reduce methane emission following application of rice straw. This study aimed to evaluate the application of rice straw and nitrification inhibitor to methne emission in rainfed lowlalnd rice system. A factorial randomized block design was used with three replications. The first factor was rice straw incorporation (5 t ha-1 fresh straw, 5 t ha-1 composted straw), and the second factor was nitrification inhibitor application (20 kg ha-1 neem cake, 20 kg ha-1 carbofuran). The experiment was conducted at rainfed lowland in Pati, Central Java, during 2009/2010 wet season. Ciherang variety was planted as direct seeded rice with spacing of 20 cm x 20 cm in each plot of 4 m x 5 m. The rice straw was treated together with soil tillage, whereas nitrificatin inhibitor was applied together with urea application. Parameters observed were methane flux, plant height, plant biomass, grain yield, organic C content, bacterial population in soil. The methane flux and soil organic C were measured at 25, 45, 60, 75, and 95 days after emrgence. The results showed that composted rice straw incorporation significantly emitted methane lower (73.2 ± 6.6 kg CH 4 ha-1 season-1 ) compared to fresh rice straw (93.5 ± 4.0 kg CH 4 ha-1 season-1 ). Application of nitrification inhabitors neem cake and corbofuran reduced methane emission as much as 20.7 and 15.4 kg CH 4 ha-1 season-1 , repectively. Under direct seeded rice system, methane flux level correlated with plant biomass as shown by linear regression of Y = 0.0015 X + 0.0575 (R2 = 0.2305, n = 27). This means that higher plant biomass produced more methane flux.The study indicates that application of nitrification inhibitors such as neem cake is prospective in decreasing methane emission from direct seeded rice cropping.

Index Jurnal Multifunctional Mutants of Azospirillum sp. with Enhanced Capability of Solubilizing Phosporus, Fixing Nitrogen, and Producing Indole Acetic Acid - Eny Ida Riyanti-Indonesian Journal Agricultural Science: Indenesian Agency for Agricultural Research and Development 1. AZOSPIRILLUM SP. - MUTANTS Abstract : Azospirillum sp. have long been known as biofertilizer for plant growth because of its capability to produce phytohormones and fix nitrogen from atmosphere. Multifunctional Azopirillum strain AJ Bandung 6.4.2.1 isolated from 2009 from cauliflower (Brassica oleracea) rizhosphere in Lembang, Bandung, West Java, was capable of fixing nitrogen, solubilizing tricalciumphosphate, and producing phytohormone indole acetic acid (IAA). The study aimed to modify the multifunctions of Azospirillum sp. for better capbility od fixing N 2 , solubilizing P, and producing IAA using ethyl methanesulfonate and 1-methyl-3-nitro-1- nitrosoguanidine (EMS) mutagen. The study was conducted at Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development (ICABIOGRAD) in 2010. The results showed that this strain was genetically mutagenized using EMS for better performance in solubilizing P, fixing N 2 (nitrogenase activity), and producing phytohormone (IAA). The optimum concetration and the length of incubation time for the process have been determined. Nine selected mutants with incresing capibility to solubilize P (determined by clear-zone-formation on Pikovskaya's medium) have been caracterized for nitrogrnase activities and IAA production compared to wild type AJ Bandung 6.4.1.2. The effect of mutagenesis on IAA production anf nitrogenase activities varied among the mutans. Two mutans. AzM 3.7.1.16 and AzM 1.7.2.12, showed superiority in production of IAA, while two mutans AzM 1.5.1.14 adn AzM 3.7.1.15, were superior in nitrogenase activities. The EMS mutagenesis of Azospirillum sp. showed enchanced dissolving capability of unsoluble phosphate (tricalciumphosphate) and increase IAA production and nitrogenase activity.

Setiawati-Indonesian Journal Agricultural Science: Indenesian Agency for Agricultural Research and Development 1. GEMINI VIRUS 2. LYCOPERSICON ESCULENTUM Bemisia tabaci (Genn). (Homoptera : Aleyrodidae) is one of the most serious pests on tomato. it is mainly controlled by chemical means, requiring some 25 sprays during the average growing season. the extensive and repeated use of insecticides has disrupted the natural balance between this pest and its natural enemies. in this study, Menochilus sexmaculatus F. was evaluated as a possible biological control agent of B, tabaci and its effect on gemini virus infestation. the study was conducted at the experimental station of the Indonesian Vegetables Research Institute (IVeGRi) in Lembang, West Java (1,250 m above sea level) from Agust to December 2008. the experimental plots consisted of 0.35 ha of tomato (± 100 m² per plot) and spatially separated with four rows of maize (a minimum of 1 m) interplot distance to prevent cross-contamination among plots. the experiment was arranged in completely randomized block design with eight treatments and four replications. M. sexmaculatus were released at 24 days after planting. the treatments were designed according dosage and schedules at three released population (i.e 10 predators per plot, 20 predators per plot. and 10 predators per plot at vegetative stage followed by 20 predators per plot at generative stage); two places of release (center dan edge of the plot); and two schedules of release (weekly and biweekly). efficacy of the predator was measured in terms of the density of B. tabaci, both before and after release of the predator and its effect on gemini virus infestation on tomato. reductions in B. tabaci population in plots receiving 10 predatorsshowed 73.62 % and 75.75 % reductions by the end of experiment. the incidence and intensity of gemini virus were consistently and significantly lowest and tomato yield gain was observed when 10 predators were released at weekly intervals. it is suggested that release of M. sexmaculatus against B. tabaci on tomato may be offered as an alternative solution to increase implementation of biologically-based B. tabaci management.

ACID SOIL 2. BRACHIARIA DECUMBENS Acid soil is commonly grown with cassava, which in general, tolerate low soil fertility and aluminium (Al) toxicity. However, without any improvement efforts such soil will become worse. Intercropping cassava with Brachiaria Decumberns (BD) which adapts to acid soil and tolerates low fertility soils as well as application of arbuscular mycorrhiza (AM) and organic matters are among the important efforts to rehabilitate this soil. the experiment was conducted to examine the impact of BD, AM, and potassium 9K) enriched rice straw compost on exchangeable Al, available K, and stability of soil aggregates. Experiment was arranged in a completely randomized design with three factors and three replications. the first factor was BD as cassava intercropping, the second factor was AM, and the third factor was 2 t ha¨¹ rice straw compost enriched with o kg, 50 kg, 100 kg, and 200 kg KCI ha¨¹. Brick pots (1 m length x 1 m width x 0.45 m depth) filled with Kanhapludult soil was used for growing cassava in which row of BD was planted at 60 cm from cassava stem. K-enriched rice straw compost and AM (10 g per stem) were applied around cassava stem at 2 and 12 days after planting, respectively. BD was cut every 30 days and the cutting was returned to the soil. soil exchangeable AL was analyzed at 0, 3, 6 and 9 months after planting (MAP), while AL and K contents as well as aggregate stability ewre measured at 6 MAP. The results showed that planting BD decreased 33 % exchangeable Al, which means that the root exudates of this grass was effective in detoxifying Al ³+. Treatment of BD and/or in combination with AM was effective in preserving K added to the soil, increasing total polysaccharides, and improving soil aggregate stability. this indicated that planting BD and applying Am and K-enriched rice straw compost improved acid soil fertility, and therefore can be recommended in cassava cultivation.

ANALISIS EKONOMI 2. STUDI KELAYAKAN Drying is a critical activity in rice postharvest handling. any delay in drying will result in quality and quantity losses. Farmers and traders prefer to sell wet grain rather than dried grain of unhulled rice due to less attractive in Subang District, West Java, during March-June 2011 using survey method to analyze the financial feasibility of rice dryers. The respondents interviewed were 15 rice millers who have either sun-drying floor or mechanical dryer, or both. The main collected data were the investment cost, operational cost, maintenance cost, and the revenue of the dryers. The data were analyzed by using short-term and long-term financial analyses to assess the profitability and feasibility of some drying technologies. The results showed that there were at least three drying technologies in the study area, namely sun-drying floor, flatbed dryer using gas fuel (gas dryer), and flatbed dryer using rice husk fuel (husk dryer). Under the mean capacity, the short-run MBCR of technological change from sun dryer to gas dryer was 1.29, while from sun dryer to husk dryer was 1.45. The long-run analysis showed that the IRRs were 44.44 % for sun dryer, 233.4 % for gas dryer, and 260.49 % for husk dryer. These results showed that among the three drying technologies, husk dryer is the most profitable, most feasible, and most prospective to be adopted. Therefore, this type of dryer should be intensively promoted to the farmers' group associations, rice traders, and rice millers. The government support in terms of rice dryers for farmers' group associations should be focused on husk dryer. [Keywords : Rice, dryers, economic analysis, feasibility study, West Java]
