Heptachlor insecticide is a toxic organochlorine insecticide, persistent and bio-cummulative in the environment. Remediation using actived carbon and microbial is a solution to pollution due to pesticide in the environment.The objective of this study was to obtain fertilizer technology using urea with activated carbon and enriched with microbes degrading heptachlor insecticide in order to reduce the insecticide residue in paddy fields. The research was conducted at the Jakenan Experimental Station between February to September 2012. The soil used as the planting medium was brought from the village Sukamenak, District Rawagempol Wetan, Karawang. The experiment was conducted in the field at micro-plot scale with lysimeter, and using a randomized block design (RBD) with 3 replications and 6 fertilizer treatments ( control , prill urea , urea with activated carbon maize cobs ( UAATJ ) , urea with activated carbon coconut shell ( UAATK ) , urea with activated carbon cob corn + microbes ( UAATJM ) , urea with activated carbon coconut shell + microbes ( UAATKM ). The plants used were from Inpari 13 variety. The insecticide residue analysis was performed in the Residu Bahan Agrikimia (RBA) laboratory of Balingtan. The results showed significant orthogonal countrast tests of different treatments. The highest reduction of residual insecticide was observed in urea coated with activated carbon cob corn and enriched with microbial consortia degrading POPs, which was 36.30 %. It is suspected that activated carbon coated cob corn with microbial enrichment was favored as its home and the microbes utilized carbon sources of heptachlor as the food.

Rambutan is a fruit native to Indonesia, which has a high diversity. Indonesian Tropical Fruit Research Institute has a rambutan germplasm collection. The objectives of the research were to identify and classify rambutan germplasm accessions based on morphological characteristics, in order to identify the specific characteristics important for the development of future varieties of rambutan. Collecting data on the 32 accession was conducted in Aripan Experimental Field, Indonesian Tropical Fruit Research Institute from September 2014 to February 2015. Characterization of morphology characters referred to as the Descriptor for Rambutan was published by IPGRI. Cluster analysis based on morphological characteristics successfully separated the accession of rambutan R7 and R11 with 30 other rambutan accessions with the dissimilarity coefficient of 45%. Accession R4 was similar to Sitangkue, R14 was similar to Korong Gadang, and R15 was similar to Sinyonya. Characteristics that can be used to distinguish each of the accession of rambutan were the width of seed, seed thickness, total soluble solids (TSS), fruit diameter, spintern texture and the spintern color. Accession R15 can be developed as a commercial variety, because it has a high yield, and shelf life associated with high fruit weight characteristics and thick rind.

Regulation in the utilization of irrigation as Common Pool Resources-CPRs is really needed to overcome water limitation. Conducive conditions for the irrigation management on overall hydrological unit will be strengthened by the presence of social capital. Social capital plays a role in the mechanism of collective action formation on the management of CPRs whose existence depends on the peopleâ€™s social and cultural environment. Trust will reduce transaction costs and facilitate the formation of social cooperation (network). Establishment of social bonds and norms in the groups become an effective instrument for resource sustainability. The study aims to analyze the role of social capital in the irrigation management and its impact to the farmers welfare. The study was conducted from April to August 2014 In Sukoharjo,with 320 respondents who represent the hydrological diversity unit of 12 districts in Sukoharjo. Using the two levels regression analysis, namely at the micro-level (farmers household) and meso-level (community) to see the effect of different variables: social capital of farmer households (Iik), social capital of community (Mk), area access (R), access and availability of water resources (Hdr), external environment (E), the collective action of irrigation management (TK), farmers satisfaction (Stfy), highly significant effect to the farmer household welfare (Sik) and community level (wk). Social capital of community, area access, access and availability of water resources have a significant effect to the society welfare (Wk). Therefore, the implementation of irrigation management should provide space for the establishment of social capital accompanied by policies harmonization between the formal regulations and informal rules in the form of the value system and culture that flourished in the society life.

An ideal soybean cultivar is the one that achieves the greatest yield consistently across many environments regardless of environmental conditions. The objective of this experiment was to determine the soybean seed yield stability by AMMI method. A total of ten soybean genotypes, which consisted of eight soybean promising lines (G100H/SHRW-60-38, SHRW-60/G100H-73, SHRW-60/G100H-68, SHRW-60/G100H-66, G100H/SHRW-34, SHRW-60/G100H-5, SHRW-60/G100H-70, and SHRW-60/G100H-75) and two soybean check varieties (Kaba and Wilis) was evaluated at six soybean production centers in Yogyakarta, Banyuwangi and West Nusa Tenggara during 2011. The field experimental design for each location was completely randomized design with four replicates. Each genotype was planted on 2.4 m x 4.5 m plot size, 40 cm x 15 cm plant distance, with 2 plants/hill. Stability analysis on seed yield was based on the AMMI method.The combined analysis showed that the genotype and GEI were highly significant for seed yield. The AMMI of the first significant interaction principal component (PC1) accounted for 66.07% of the total variation. Based on AMMI1 biplot, G1 (G100H/SHRW-60-38) and G5 (G100H/SHRW-34) showed higher yield stability. However, the most stable genotype (G5) produced low yield. The other stable genotype (G5) showed highest soybean yield, and therefore it is proposed to be released as a new improved soybean variety.

In Indonesia, corn mainly use as feeds in particular for poultry. Sustainable national corn self-sufficiency is an ideal condition for Indonesia which has the availability Â Â natural resources and supporting agro-ecological environment. The gap between supply and demand of corn is still relatively large due to the high demand of corn, especially for feed. To attain national corn self-sufficiency, the Government intervened national corn supply by implementing Â of the national corn self-sufficiency policy. This study aims to analyze the increase of corn extensification and productivity by dynamic system approach. Validation on the built-in model showed that the model was valid. The simulation results showed that before the implementation of corn self-sufficiency policy Indonesia was unable to achieve self-sufficiency, and, on the other hand, after the policy implementation the simulation result showed that the sustainable corn self-sufficiency is attainable. Model simulation results showed that extensification and productivity improvement strategies (combined scenario of increased extensification and productivity) were able to increase the production of corn to as many as 25.85 million tonnes through extensification increase and 26.69 million tons through productivity increase.

The success of selection in plant breeding program is determined by genetic variabiliities, heritability values and the correlation between agronomic characters and yield. The study aims to determine the genetic variability, heritability and the effec of agronomic characters to grain yield. The experiment was conducted in February to May 2016 in Grobogan, Central Java. The experiment consists of twelve genotypes of maize hybrids, arranged in a randomized block design with three replications. The characters observed were plant height, ear height, number of harvested ear, shelling percentage, moisture content of grain harvested, weight of 100 grains, ear length, ear diameter, number of rows per ear, number of seeds per row per ear, and grain yields. The results showed that the genetic variability of agronomic characters was broad, except ear diameter. Almost all of the heritability values of yield components were high, except harvested ear weight and ear diameter. The characters of plant height, ear height and as the genotypic gave high of a direct effect on the yield higher, while direct effect of the phenotypic character of ear hairves on grain yield are higher.

Informasi tentang data produksi diperoleh dari pengumpulan data luas panen dan produktivitas. Pengumpulan data produktivitas padi dengan pendekatan rumah tangga yang dilakukan sering dianggap kurang representatif. Pusdatin mengembangkan dan melakukan uji coba metodologi area frame untuk pengukuran produktivitas padi yang bertujuan untuk menghitung rata-rata hasil produktivitas padi dan membandingkan dengan hasil pengukuran produktivitas padi melalui survei ubinan reguler. Metode yang digunakan adalah penarikan contoh acak sistematik.Faktor yang mempengaruhi program peningkatan produktivitas padi, yaitu sampel untuk ubinan jatuh pada dataran rendah/tinggi dan adanya program SL-PTT/tidak ada program SL-PTT. Survei dilakukan di Kabupaten Cianjur dan diperoleh hasil 90 petak jatuh pada dataran tinggi dan 310 petak pada dataran rendah. 56 petak mengikuti program SLPTT dn 344 petak tidak mengikuti program SLPTT dengan jumlah sampel 400 petak. Hasil uji perbandingan ratarata berat ubinan metode Area Frame dan Listing Frame berdasarkan kecamatan menunjukkan hasil nilai p-value di 12 kecamatan atau sebanyak 75% tolak Ho, yang berarti terdapat perbedaan signifikan antara ubinan metode area frame dan listing frame . Sedangkan berdasarkan pada wilayah kabupaten menunjukkan nilai p-value 0,493 (terima Ho), yang berarti tidak terdapat perbedaan yang signifikan antara ubinan metode area frame dan ubinan listing frame . Hal ini menunjukkan bahwa keragaman hasil ubinan padi di dalam kecamatan lebih tinggi dari pada pada keragaman hasil ubinan seluruh wilayah kabupaten.Metode area frame memiliki keuntungan lebih, yaitu lokasi ubinan yang jelas karena dipetakkan dengan cermat sehingga tidak akan bergeser di luar mesh yang terpilih.
