No full textFahroji et al, 2016. 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

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
Mobilisasi Bibit Padi Unggul sistem Dapog antar Kabupaten Sebagai Alternatif Penyediaan Bibit Padi Guna Mendukung Percepatan Tanam Padi di Kalimantan Selatan
No full textSabur et al, 2016. Paddy Seed Superior mobilization Dapog system between the District as an Alternative Provision Paddy Seed to Support Accelerating Paddy Planting in South Kalimantan. JLSO 5(1):43-52.Breeding technology using dapog can be an alternative for the provision of rice seeds that can be mobilized anywhere even distances. In application required correct technique when the rolls of rice seeds will be moved so that no damage, and rice seeds can be used for optimal planting. The purpose of this study was conducted to determine the proper technique for memindahan seeds to great distances that use dapog seedlings, and to know which crop performance in mobilization after two weeks grown in paddy fields. This activity was conducted in August 2016, the nursery of paddy system dapog carried out in the village of Bungur New District of Tapin Central Tapin district, the rice seedlings were transferred to the village of Pangambau Hulu subdistrict Haruyan Hulu Sungai Tengah with the distance of 69 km and takes about 1 hour and 25 minutes to then directly planted in paddy fields that had been prepared. The research method with direct observations and describe. From the observation data obtained as follows, 230 rolls of seeds brought, 222 rolls can be directly planted using planting machines Jarwo trasplanter. In addition the level of damage to a minimum or an average of 1.5%, while the highest damage is due to wither due to the distance and wind by 2% or 5 rolls of a total of 230 scrolls were brought, and position rolls of rice seedlings that much gain exposure is positioned on top of the pile. Vibrations caused by road conditions are not smooth when seedlings in mobilization also occurred on a roll topmost ditumpukan seedlings, the number of rolls fall apart as much as 2% or 5 reels. The rolls are oppressed due stacked seed and seedlings were damaged due to errors at the time of rolling 1%. Placements are set up well during the trip, and experienced technical personnel, making seed rolls only minimal shifting. Mobilization time better morning and the movement speed of the car attempted stable with an average speed of 40-60 km / h on a smooth path to reduce wind into rolls seed and on the bumpy roads the speed reduced to 10-20 km / h or adjust to the road conditions so that the vibration can be minimized

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

No full textAprisal. et al. Dynamics of Some Physical Properties of Soils Under Conservation Farming System on the Critical Land Aripan in the DTA Singkarak. JLSO 5(2):137-144.The conservation farming on critical land can improve the soil properties and maintantain for a periode of time. The purpose of this research is to study the dynamics of critical land’s physical characteristics under the influence of conservation farming at Singkarak Water Catchment Area (DTA) in Nagari Aripan. The analysis of soil sample is conducted in Soil Science Department Laboratory, Faculty of Agriculture, Andalas University. This research is designed with Split Plot Design (RPT). The main plot is a soil processing system which is: conventional soil processing (po), soil processing with mulch (p1), soil processing with compost and manure (p2) and minimum soil processing (p3), while the sub plot consists of three types of plants, they are; sweet corn (t1), soy bean (t2) and peanut (p3). Each treatment is repeated three times. Result of the research is observation data in each season of the first, second and third year. To see the dynamics of soil characteristics, data of each season is viewed through graphic which based on its trend. The result of the research indicates that utilization of critical land with conservation farming system could repair and maintain some physical characteristics of soil in each growing season, such as: decreasing volume, increasing soil organic matter, porosity, and soil permeability. Productivity of soil increases on the conventional processing with mulch, compost, and manure. Conventional soil processing with added compost and manure increases productivity for 32.58% in the first year, 45.16% in the second year, and 59.73% in the third year

JLSO 5(2):119-126. Tillage and mulching are intended to create good soil conditions which is suitable for plant growth so could increase crop production. This study aims to gain tillage system and the organic mulching which can improve the growth and the production of sweet corn on the dry land. The experimental design used in this study is a randomized block design arranged as factorial with two treatments factors and three replications. The first factor is tillage (P), which consists of no tillage (P0), minimum tillage (P1), and maximum tillage (P2). The second factor is mulching (M), which consists of no mulching (M0), mulching (M1). The results showed that  tillage systems affect the growth and production of sweet corn, mulching no effect on the growth and production of sweet corn, and mulching on minimum tillage tend to affect both the growth and the production of sweet corn on dry land
