Jumakir et al, 2016.Â TestÂ of Some Packages FertilizationÂ and Dolomite to Soybean YieldÂ in Tidal Swamp LandÂ Province Jambi. JLSO 5(1):86-94.The purpose of this study was to determine the performance and productivity of soybean with various package fertilization and dolomite in tidal swamp land. This assessment was conducted in tidal swamp land with potential acid sulphate soil typology and type of flood water C, Simpang Village Berbak sub District,Â East Tanjung Jabung District of Jambi Province in the dry season 2013. The design used was a randomized block design (RAK) with seven treatment and seven replications with an area of 100 m2 each treatment. The assessment results based on the analysis of variance showed significant differences on growth and yield of soybean. Urea fertilizer application, Phonska, and Biofertilizer increase soybean yield 19,61% - 25,25%, while fertilizer Phonska, Dolomite, Manure and Biological Fertilizer soybean yield increased 28,07% - 31,49% compared to the fertilizer Urea and Phonska. Fertilizer application, Phonska, Dolomite, manure and biological fertilizers Soybean Plus gives the highest yield that is 1,89 t/ha.

Wildayana et al, 2016.Â Matching Global Crises with Application of Production Factors and Income of NES Oil Palm Plasma Farmers. JLSO 5(1):10-17.The research aimed to analyze the global crisis adjustment to the production factors and income of NES oil palm smallholder. The research location is located in swamp land Talang Sepucuk, OKI District (PIR Trans) and PIR Bun is sited in Betung Banyuasin, South Sumatra. The research method was a field survey using a questionnaire to smallholders. Collected data are statistically processed with SPSS version 21. The research concludes that the global crisis has led to a very significant reduction in the use of fertilizers and pesticides and the significant differences in the utilization of manpower. The use alsintan showed no significant difference. Very sharp reduction has occurred in PIR Bun compared to PIR Trans smallholder farmers. As a result of the global crisis, the PIR Trans smallholder incomes decreased by 25.76% and PIR Bun decreased by 36.95% and vary significantly due to the global crisis. But the distribution of smallholder incomes do not show the proportion of the difference.

Taqwa et al, 2016.Â The Using of Cucumbar Extract to Reduce the Stress Level and Increase the Survival Rate of White Shrimp Postlarvae (Litopenaeus vannamei) during Salinity Decreasing Time. JLSO 5(1):53-61.The purpose of this study was to evaluate the effect of adding cucumber extract on the level of stress and survival of white shrimp postlarvae during acclimatization. The method used was completely randomized design with five treatment and three replication of adding cucumber extract that equal 15 ppm (T1), 30 ppm (T2), 45 ppm (T3), 60 ppm (T4) and without adding cucumber extract (T0) as a control. The results showed that addition of cucumber extract equivalent to 15 ppm (T1) in diluents media during 96 hours of acclimatization produce survival 91.67%, body fluid glucose levels are lower at 161.67 mg dl-1 and consumption level of oxygen 4.39 mg O2 g-1 h-1. Physical chemistry value of media acclimatization still in tolerance except in ammonia

Fahroji et al, 2016.Â Evaluation of Moisture Meters Performance on Determination of Water Content of Rough Rice. JLSO 5(1):62-70.Moisture content is an important parameter for determining of rice quality. The water content of rough rice affects on milling process because if water content is high, more than 14% of high will result broken rice. The purpose of this research is to study the reliability of moisture meters on determination of the water content of rice grain, accuracy, precision and reproducibility. The sample of measurement are rough rice with 5 different water contents (12%, 14%, 16%, 18% and 20%), while the equipments to be evaluated are the resistance type of moisture meters (Gwon1, Gwon2 and Gwon3), the capacitance type (Kett and Gac), the direct method (type infrared and hot air oven). AOAC method is used as a standard because of its more accurate than the other methods. The result showed that moisture meters performed strong relation with moisture content measured by AOAC as the reference. Kett meter was more accurate than the other moisture meters. All meters showed not satisfied in reliability indicator including accuracy, as well as for Allowed Quality Limit (AQL). Measurement of precision value of resistance type moisture meters indicated high precision and reproducibility from 3 meters are not satisfied.

Chuzaimah et al, 2016.Â The Factors that affect to Swamp Rice Farming IncomeÂ in Pemulutan Ulu Village, Ogan Ilir District. JLSO 5(1):27-34.Good management of rice farming is indispensable in order to increase farmers' income. Good management can not be separated from social and economic characteristics inherent in farmers. This research aimed to determine the factors that affecting swamp rice farming income. The research used survey method, where Pemulutan Ulu Village, Pemulutan Subdistrict, Ogan Ilir District been intentionally (purposive) as a research location. The sample was selected as many as 30 farmers from 302 population using stratified random sampling method, based on the extent of land ownership < 0,5 hectare, 0,6 to 1 hectare, and > 1 hectare. The results showed that swamp rice farming was profitable with farming income of Rp14.026.652,00 per hectare per cropping season with the R/C of 3,94. Factors that affected the income of swamp rice farming were the life of farmers, land size, and farming experience.

Sumardi et al, 2016.Â Ratoon Performances of Rice Lines Generated from Bengkulu Local Varieties on Inland Swamp. JLSO 5(1):71-78.Ratooning offers an opportunity to increase rice production under swampy areas commonly hampered by a limited growing seasons due seasonal water level fluctuation. Present study was undertaken to evaluate the ratoon growth and yield performances of rice lines grown on inland swamp. Eight F4 lines derived from crosses involving Bengkulu local swamp rice varieties (UBPR1, UBPR2, Â UBPR3, UBPR4, UBPR6, UBPR7, UBPR9, and UBPR10)Â along with two released varieties (Inpara5 and Inpara 6) were grown on inland swamp under a randomized complete block design with three replications. Data were collected on ratoons emerged following harvest of the main crops for plant height,Â total tiller number,heading date, productive tiller number, panicle length, grain number per panicle,percent of filled grains per panicle, 100 grain weight,Â and grain yield per hill. Results indicated significant variations among the genotypes for most of the observed variables, except total tiller number, grain number per panicle, and percent of filled grains per panicle. UBPR10had produced highest total tiller number (12.6) and productive tiller number (11.6). UBPR1 produced the highest panicle length (19.0 cm) and grain number per panicle (66.43).Â UBPR3 exhibited the tallestÂ (100.13 cm) and highest grain yield per hill (12.023 g), but most delayed heading date (18.0 d).Â With respect to the productivity of Â ratoon,Â UBPR 3 showed the most productive lineby yieldingÂ grain 49.54% of the main crop yield.

Helmizuryani et al, 2016.Â Productivy of Feminization of Anabas testudineus Larvae Used Fruits Extract by Dipping Method. JLSO 5(1):35-42.Anabas testudineusis one of indigenous fish in Indonesia spread on swamp and river, need attention because the population endangered and higher people consumption. This research aims to identification fruits extract function toward larvae feminization. It has dipping together with larvae for 10 hours, which doze 3 ml/l by different fruits extract.The larvae was 7 days old. After dipping, it has rearing on aquarium during 90 days became seed stage which observation sex ratio and seed growth.Â This research was conduct on hatchery at Community Unit â€œMuliaâ€ Plaju, Palembang and Chemical Laboratory, University of Muhammadiyah Palembang from Februari until April 2016. Larvae was got from broodstock reproduction at hatchery. Experiment method used completely ramdomized design and three treatment of different fruits extract, and three repetation.The treatment are P1: the avocado extract, P2: the bengkoang extract, and P3: date palm extract. The experiment showed the higher survival rate was P2 (64,44%), the higher length growth was P1 (3,11 mm), the highest weigth growth was P1 (1,03 gr). The best sex ratio for female was P1 (74.07%).The best sex ratio for male was P2 (48,12%).
