Abstract

Banyuasin district is one of the rice producing regions in South Sumatra which rely on sub-optimal land type with category tidal land to produce rice production. The statistical data showed that Banyuasin District is a region that produces the highest rice production of rice-producing areas in South Sumatra. However, the high level of production is not able to guarantee farmers' income is also high, and prices at the consumer level will be low. This is because rice prices received by farmers is still relatively quite low. The condition is the main attraction of researchers to conduct this research with the aim to analyze the pattern of marketing tidal swamp rice production through the analysis of marketing channels, marketing margins, marketing efficiency level and method of pricing of each institution tidal swamp rice marketing in the District Banyuasin This study was conducted in District Rambutan Banyuasin Regency, with time data collection in April-May 2014. The results showed that there are two groups of marketing channels tidal swamp rice production in the district which are both classified as Banyuasin indirect marketing channels. Pricing method of rice is determined by the merchant so that farmers are recipients of the price (price taker) while marketing agency is a price maker. The calculation of the value of marketing margins in both marketing channel marketing agency in each figure shows the range varies with Rp.400 per kg to Rp, 3,100, - per kg. The analysis shows that the pattern of marketing efficiency marketing tidal swamp rice production is already relatively efficient, with the highest levels of efficiency are the major traders.

The application of biochar and water table at one month after planting on growth and yield of shallot. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands. 8(2):202-212. The success of onion self-sufficiency is the arrangement and growth of production centers that are not only concentrated in Java. The research aimed to evaluate the effect of biochar application and water table treatment on growth and yield of shallot plant. The research was conducted in Experimental Farm of Agriculture Faculty, Sriwijaya University at 2019. Materials used consisted of shallot bulb of Bima Brebes variety, oil palm shells biochar, paper bag, and plastic bag. While the tools used were hoe, gauge, pH meter, basin, scale, and oven. Factorial Randomized Block Design was used with two factors and three replicates. The first factor was biochar dosages consisting of P1 (51 g/plant) and P2 (102 g/plant) and the second factor was soil water table consisting of T0 (no water table treatment), T1 (10 cm of water table below soil surface), T2 (15 cm of water table below soil surface) and T3 (30 cm of water table below soil surface). The observed parameters included plant height, leaf number, tiller number, total bulb fresh weight, bulb fresh weight, bulb dry weight and root length. Results showed that the application of biochar and water table treatment statistically affected the growth and yield of shallot plant. The effect on both growth and yield parameters were obtained from the combination of P2T3. Correlation was found between plant height and leaf number, total bulb fresh weight and bulb fresh weight.
