Abstract

Chuzaimah, et al. Rice Farmers Technology Applications Swamp Paddy in the Distric Ogan Ilir Sumatera Selatan. JLSO 5(2):127-136.Lowland swamp land development for agriculture, especially food crops on a large scale requires land arrangement and the network of water management and the application of technologies appropriate to local conditions in order to obtain maximum results. The purpose of this study was to analyze the swampy lowland rice technology applications, revenues and relationships both in Ogan Ilir. This study was conducted in Ogan Ilir District of South Pemulutan Cahaya Marga village. Sampling method in using Simple Random Sampling, by taking 30 farmers. Data collected consist of primary and secondary. This study was analyzed by using Likert scaling technique. The results showed that application of high technology swampy rice paddy where the average application of technology in Desa Cahaya Marga is 19.23 which is the recommended. For each application technology swampy lowland rice fertilization has not seen only as recommended. Additionally pest and disease control in the application of technology swampy rice paddy in the village of Light Marga has not as directed seen from the scores just 2.13. The amount of household income of farmers in Desa Cahaya Marga is Rp 9,845,591 cultivated area per planting season per year, while total household income of farmers in Desa Cahaya Marga is Rp 20,593,336 per year. Simultaneously Application technology (X) significantly affects the productivity of lowland rice paddy (Y) where Fhit = 0.79 to be significant at the level α = 0.05 (5%), even at the 1% significance level, there is a positive relationship between the application of technology  with revenues.

Abstract

Sari et al, 2018. Productivity and an Enlarge Minimum Land Area of Paddy’s Farmers in Swamp Land of the Ogan Ilir Regency. JLSO 7(2):185-195.South Pemulutan is one of the sub-districts in Ogan Ilir Regency which has swamp paddy fields potential to be developed. Unfortunately, the use of production factors which applied by the farmers has not been maximized. Therefore, proper management by using production factors efficiently and effectively can increase productivity and maintain the sustainability of their farm. Moreover, the aims of this research were (1) to analyze the factors which affect the low productivity of the swamp paddy fields, (2) to calculate the percentage of an income of the swamp paddy fields’ farmer which can fulfill their household outcome, (3) to calculate the minimum land area of the swamp paddy fields of the farmer. The method were used in this research was survey method. The sample of the farmers which taken in this study were 30 farmers from 187 farmers which works on swamp paddy fields in Lebak Pering village. The data was gathered consist of the primary data and the secondary data. The result of this research showed (1) factors which extremely affected toward swamp paddy fields productivity in Lebak Pering village was the largest of the area, seed variety, the used of urea fertilizer, the experiences of the farmer, while those that have no effect are the used of SP-36 fertilizer, NPK fertilizer and then the pesticides. (2) The contribution of swamp paddy fields farmers’ income to farmers' consumption expenditure were 60.28%. (3) The minimum land area that suggested to be cultivated by the farmer is 1 hectare and if the farmer only relies on their swamp paddy fields farming, then the minimum land area that suggested to be raised by the farmer is 1.66 hectares.

Abstract

Ketergantungan masyarakat terhadap minyak bumi menempati proporsi terbesar dalam pemakaiannya sebagai sumber energi penduduk. Bioetanol merupakan bahan bakar dari minyak nabati yang memiliki sifat menyerupai minyak premium. Nasi aking merupakan limbah yang banyak mengandung karbohidrat. Kandungan karbohidrat pada nasi aking sangat berpotensi sebagai sumber bahan bakar nabati ramah lingkungan yang dapat dikembangkan sebagai energi bahan bakar alternatif. Pada penelitian ini dilakukan pembuatan bioetanol dengan bahan baku nasi aking. Variabel yang dikaji adalah konsentrasi enzim (4,6,8,10,12 gr) untuk menentukan konsentrasi enzim terbaik. Didapatkan konsentrasi enzim terbaik adalah 8 gr setelah proses fermentasi selama 24 jam. Selanjutnya dilakukan pengamatan waktu fermentasi (24,48,72,96, 120,144,168,192,216 jam) untuk menentukan waktu fermentasi terbaik dengan melihat kadar bioetanol dihasilkan. Dari penelitian didapatkan waktu fermentasi terbaik adalah 168 jam dengan kadar bioetanol dihasilkan 26,464% melalui analisa Gas Chromatography dengan nilai kalor 190,9833 kkal/kg.
