Dhania Sari et al, 2017. Farm System Feasibility of New Prime Variaty in Rained Rice Field in Ogan Komering Ilir Regency South Sumatera Province. JLSO 6(2):120-125.Economic feasibility is farmersâ€™ main consideration in implementing technology innovation in their rice farming business. The increase of farmersâ€™ revenue can be obtained through the production improvement, and through the use of New Prime Variety which is one of the technology component that is able to increase rice production. Rainfed rice field in Ogan Komering Ilir (â€˜OKIâ€™) Regency which covers 9,397 hectares is potential for further production optimality. This study aims to understand the revenue of rice farming business through the use of New Prime Variety in Rainfed Rice Field, and also to understand financial feasibility of New Prime Variety rice farming business in OKI Regency. The study method was undertaken by Plot Demonstration in Cahya Maju Village, Lempuing Sub District, OKI Regency in April - June 2016 for 2 hectares area. The data consists of primary and secondary data. The technology was implemented with Inpari 15, Inpari 20, Inpari 22, Inpari 27, Inpari 29, Inpari 30 Variety, and with Ciherang Variety as a comparison and also with the integrated plant management. The data analysis method is using tabulation and financial analysis. The study result shows that Inpari Variety has the highest financial gain with IDR 31,254,000. Economic wise, all varieties are financially feasibile, which is shown by the R/C ratio > 1.

Suparwoto et al, 2019.Â The Growth and Production Three Rice Superior Varieties in Swampy LandsÂ at the Jambu Ilir Village, Ogan Komering Ilir District. JLSO 8(1):39-46.The assessment was carried out in Jambu Ilir Village, Tanjung Lubuk District, Ogan Komering Ilir Regency, South Sumatra, starting in the dry season of 2018. Varieties exhibited were 2 superior varieties Â and 1 comparative variety, Mekongga. The aim of the study was to obtain information on the growth and production of Inpari 30 and Inpara 8 varieties that were adaptive and had high production on lebak lands. The study was designed by observation method, spacing of legowo 2: 1 (50x25x12.5 cm), seedling age 35 days after seedling, 2-3 seeds / holes. The dosage of fertilizer used is 150 kg Urea, 100 kg SP-36 and 100 kg KCl / ha. The variables observed were: plant height, number of productive tillers, number of grain per panicle, number of filled grains per panicle, and grain yield per ha. The data obtained was arranged in tabulation and analyzed by statistical tests, namely the test of the mean value (test-t). The results showed that the plant height of the varieties exhibited was classified as low to moderate with the number of productive tillers classified as moderate. Inpari 30, and Inpara 8 can adapt well in lebak lands with a production of 5.1-5.3 tons GKP / ha higher than Mekongga as a comparison variety and are highly favored by farmers.

Juwita Y, Karman J, Hutapea Y, Suparwoto S. 2020. Suitability of rubber plantation land intercropped with corn (Zea mays L) plants in Kelurahan Betung. Jurnal Lahan Suboptimal: Journal of Suboptimal LandsÂ 9(1): 73-79.Rubber is one of the leading commodities of plantations in South Sumatra, especially in Banyuasin District. The opportunity for unused footpath land is a big potential in increasing farmers' income. In Betung Village, besides rubber, the community also raises livestock such as cows. This study aimed to provide information on the actual soil fertility status and see the suitability of the land in the study area when planted with corn plants, as well as the recommendations for the needed technology. The study used a survey method and the soil samples were taken using purposive random sampling method by determining the point diagonally and analyzed in the laboratory. The results of the study showed that the land suitability class at the location was according to the marginal with the limiting factors of water availability (rainfall) and nutrient retention (KB and pH). To obtain optimal corn production results, it is recommended to prepare a rainwater collection area and the addition of lime and organic matter.
