Abstract:Indonesian Swampland Agricultural Research Institute is one of the UPT-Technical Implementation Unit conducting UPBS Management Unit of Extension Seed which provide swamp rice seed.The object of research was to study the preference of farmer on the characterization of 12 varieties in tidal swampland.The researchwas conducted on farmer’s fields at Bunga Karang village, Mandastana district, Barito Kuala regency,and the survey was at Samuda village, Belawang district, Barito Kuala regency in 2016. Thirty-three farmers were be taken randomly as respondent. Characteristics of farmers, plant morphology, yield and texture of rice were collected as primary data source by observation and interview. The data were analyzed descriptively.The preference of farmers to plant morphology such as plant type, plant height, tillers and panicle length of all varieties were preferred by both Javanese and Banjarese farmers, except Inpara 1 and Inpara 5. For plant age preference, except Inpara 4, all varieties were preferred by respondents. Meanwhile Inpara 5, Inpara 7, Mekongga, and Ciherang were not preferred varieties by all farmers according to resistence to pests (stem borer and Leptocorisa oratorius) and diseases (blast). All farmers preferredthe physical of grain, rice quality, color, and taste of rice.

Abstract:Increasing of significant population also resulted in increased national food needs. Conversion of arable land into non-agricultural land make suboptimal lands became the target of planting areas to fulfill food security. Swamp land is one of suboptimal land which potential to be developed. Swamp land in Indonesia (33.40 to 39.40 million ha) has a huge potential to support the stability of the national rice production. In addition to abiotic stresses, biotic stresses also often occurs in swamp lands. This study aims to select the lines which have high yield and resistant to bacterial leaf blight (BLB). This experiment was conducted at Muara, Bogor in April-September 2014. The materials are 318 lines with five check varieties namely Inpara 2, Inpara 3, Inpara 6, Inpara 7, and IR42. The experiment was arranged in a augmented design. Observation were made on plant height, tiller number, age of flowering, age of maturity, yield, scores of bacterial leaf blight (BLB), and a score of phenotypic acceptability (PACP). Data were analyzed using SAS version 9 for analysis of variance and continue with path analysis and weighted standardized selection index. The results showed that there were sixty lines selected based on weighted standardized selection index. The lines have a yield between 4.48 to 7.48 t / ha and promissing to the next test. Three lines have yield which significantly higher than Inpara 2 namely B13100-2-MR-2-KA-3-2 (7.48 t / ha), TDK-Sub 1 1- MR-1 (7.04 t / ha), and B13991E-KA-25 (6.98 t / ha). TDK-Sub 1 1- MR-1 and B13991E-KA-25 also have resistance to bacterial leaf blight.

Abstract:One alternative to accelerate the decomposition of lignin or cellulose organic matter is to use microorganisms. Bacterial combined with fungi and synergistic will produce good compost. To ensure the viability and effectiveness of the decomposer microorganisms a suitable carrier material is required. The objective of the study were to obtain a combination of microorganisms isolates (bacteria and fungi) in accordance with the formulation of the carrier in supporting their viability and effectiveness to decomposting of maize biomass. The results showed that the combination of isolates E7.7 + P7 and B7.1 + O5 up to 28 weeks' storage were relatively superior than Promi and EM4. At 28 weeks storage, population of bacterial E7.7+P7 is 2,1-2,75x109 cfu/g and fungus 0,3-0,48x109 cfu/g, isolate B7.1+O5 had bacterial 1,38-2,5x109 cfu/g and fungus 0,2-0,3x109 cfu/g. While Promi and EM4 had bacterial were about 0.1-1.5x109 cfu/g and fungus 0.1x109 cfu/g. Both of these isolate to decomposition of maize biomass had lower C/N and water content, and higher P and K content than EM4. Therefore, both of the combination of bacteria and fungi (E7.7 + P7 and B7.1 + O5) are worthy to biodecomposer for the making of compost fertilizer. To maintain viability and effectiveness of microbe E7.7+P7 was a better to use sago+compost, while for the combination of B7.1+O5 can using sago+compost and alternative is rice water+zeolit carrier material. The results of identification based on 16S rRNA sequence showed that isolates B7.1 and E7.7, respectively were Bacillus cereus strain ATCC14579 and Brevundimonas diminuta strain NBRC12967, while isolates of fungus O5 and P7 respectively were are Aspergillus fumigatus strains KARVSO4, and Aspergillus fumigatus strains DAOM-21534-28S.

Abstract:Tanaman padi memiliki peran politik sebagai tolak ukur keberhasilan pemerintah di bidang pertanian. Pemerintah daerah membutuhkan data produktivitas tanaman padi hingga level kecamatan untuk mendukung program swasembada pangan. Permasalahannya, BPS tidak dapat menyajikan data produktivitas tanaman padi hingga level kecamatan karena ukuran contoh pada Survei Ubinan tidak representatif untuk penyajian data hingga level kecamatan. Tujuan dari penelitian ini adalah melakukan pendugaan data produktivitas tanaman padi dan produksi beras per kecamatan di Kabupaten Seruyan Provinsi Kalimantan Tengah Tahun 2016. Kabupaten ini dipilih karena memiliki lahan menganggur yang besar mencapai 479ribu hektar. Metode yang diajukan untuk menyelesaikan permasalahan di atas adalah menggunakan Geoadditive Small Area Model. Keakuratan pendugaan akan dievaluasi dengan nilai RMSE (Root Mean Squared Error) menggunakan metode jackknife dengan proses resampling. Hasil penelitian menunjukkan produktivitas tanaman padi di Kabupaten Seruyan memiliki kecenderungan bahwa semakin ke hilir Sungai Seruyan maka produktivitas tanaman padi menjadi semakin besar. Produktivitas padi tertinggi berada di Kecamatan Seruyan Hilir Timur (34.58 ku/ha) dan terendah di Seruyan Hulu (19.93 ku/ha). Hasil dugaan dengan model Geoadditive Small Area memberikan hasil yang akurat dengan nilai RMSE yang kecil. Dari seluruh kecamatan di Kabupaten Seruyan, hanya empat kecamatan mengalami surplus beras yaitu Kecamatan Seruyan Hilir Timur, Danau Sembuluh, Seruyan Hulu, dan Suling Tambun sedangkan enam kecamatan lainnya mengalami defisit kebutuhan beras. Secara keceluruhan, Kabupaten Seruyan selama tahun 2016 mengalami defisit kebutuhan beras sebesar 8 236.80 ton.Kata kunci: Produktivitas padi, Geoadditive Small Area Model, Surplus/ defisit beras.

Abstract:Financial feasibility and added value analysis of home scale-agroindustries development based on cassava commodity in Barito Koala District, South Kalimantan. Cassava processing into food products aimed to improve shelf-life of fresh cassava in order to be feasible to be consumed and to give added value in order to improve cassava’s selling value. Prospect of home scale-agroindustries development based on cassava was observed by analyze their financial feasibility and added value. Research location was detemined using purposive sampling method; while sample taking was determined using simple random sampling and key person methods. Data obtained was analyzed using both qualitative and quantitative descriptive methods. Stages of financial feasibility and added value analysis were production cost analyses, revenue, benefit, and efficiency (B/C ratio), and added value. Home scale-agroindustries based on cassav in Barito Koala District have prospect to be developed. However, with B/C ratio greater than 1 (1.67), cassava chips industry has more chance to be developed due to it is more efficient and feasible. The highest added value ratio as well as benefit ratio i.e. 63.13% and 90.79% respectively, showed that the chips indsutry can give the high added value and benefit for producer.

Abstract:An effort to increase rice production is the use of new varieties (VUB). VUB is a major technology component in the application of Integrated Crop Management (ICM). The purpose of the assessment is to look at the performance of growth and yield of paddy VUB compared with common rice varieties planted by farmers. The assessment was conducted in farmer's land in MK I (April-July 2015) in rural districts Ranggo Pajo Dompu involving four farmers, with a total land area of 1.0 ha. Assessment prepared following the randomized block design (RAK) with four replications. A total of five (5) VUB tested as a treatment : Inpari 10, Inpari 16, Inpari 19, Inpari 22, Inpari 30 Ciherang sub 1 and Cigeulis (control). In this study also apply row planting legowo system 2: 1 (spacing of 40 x 20 x 10 cm). Parameter observed among others: plant height, number of productive tiller, the number of grains / panicle, weight of 1000 seeds, dried grain yield harvest. Data were analyzed using analysis of variance (ANOVA) with the software DSAASTAT versi 1.101 and if there are differences among the treatments, it will be tested further with the Least difference significant test (LSD) at 5% level. The study showed performance of growth and yield components of new varieties (VUB) of paddy in all the observed parameters give significantly different results against paddy than varieties commonly grown by farmers (varieties Cigeulis). The results obtained at the Inpari 30 Ciherang sub 1 (5.57 t/ha GKP), followed by Inpari 19 (5.20 t/ha GKP); Inpari16 (5.43 t/ha GKP); Inpari 22 (5.20 t/ha GKP), Inpari 10 (5.19 t/ha GKP) and varieties Cigeulis (5.06 t/ha GKP). Based on the preferences of farmers Inpari 30 Ciherang sub 1 is quite unpopular compared with other varieties.

Abstract:Almost the entire planting of soybean commodity on Sumatra island has decreased. Mostly due to the low soybean productivity so that soybean farming is less attractive and encourages many farmers to switch to other commodities such as corn, peanuts and cassava. The low productivity of soybean is also due to limited capital to buy production facilities in the form of seeds, fertilizers and pesticides while the price of production facilities which from year to year tend to increase, especially the price of artificial fertilizers and pesticides Besides, the price of soybean during the harvest time is not stabilized and often less profitable farmers. This study aims to measure the level of economic efficiency that includes technical efficiency and allocative efficiency (price) in soybean farming in East Lampung, so it is expected to know the influence of the number of inputs used in soybean farming on the resulting output. Analytical methods used technical efficiency analysis using Data Envelopment Analysis (DEA) application, cost / allocative efficiency analysis and economic efficiency analysis. The results showed that the average technical efficiency of soybean farming system = 1 means that in general the soybean farming has reached the level of technical efficiency. The average value of the allocative efficiency of 1,4 means that on average the allocative efficiency level of oybean farming has not been achieved. The value of economic efficiency 1.4 is greater than 1. This means that maximum economic efficiency in East Lampung regency has not been achieved, therefore the use of production factors need to be added in order to achieve efficiency condition.

Abstract:The impact of deltamethrin on natural enemies can be determined directly through contact and oral applications or indirectly through residues on plants. This research was aimed to determine the indirect impact of deltamethrin on the egg parasitoid of Anagrus nilaparvatae. The rice plants of Cisadane variety were infested with 10 gravid females of N. lugens. Deltamethrin was applied at two concentrations (12.5 and 6.25 ppm) and at 7, 3, 1 day and 3 hours before the parasitization. Deltamethrin residues on rice plants were decrease the number of Nilaparvata lugens, parasitoid and parasitization level of A. nilaparvatae. This suggests that deltamethrin residue on rice plants could decrease the role of A. nilaparvatae in controlling N. lugens.

Abstract:Maydis leaf blight disease caused by Bipolaris maydis can attack corn plants in the vegetative and generative phase and can reduce yield up to 70%. Biological control of plant diseases with the use of biopesticides alone or in combination with other botanical materials can be efficient because it is easy to obtain, cheaper price, also environmentally friendly. The objective of the study was to obtain a combination of B. subtilis formulation with a botanical pesticide which has the potential to control the growth and development of maydis leaf blight. In addition to this, we also observed the effect of the application of the combination of botanical pesticides and B. subtilis formulation on plant growth. The study was conducted on February till June 2016 at the Plant Pathology Laboratory of ICERI with a complete randomized design and the Bajeng Experimental Farm using a randomized block design. In vitro testing, the treatment with vegetable pesticide of clove leaf extract gave better results in suppressing B. maydis. Similarly, in field testing, the application of B. subtilis formulation combined with clove leaf extract also gave a better effect in suppressing the development of maydis leaf blight disease and increasing yield. Applications of B. subtilis formulation can suppress maydis leaf blight disease by up to 13% and potentially increase yield by 26%.
