The effects of supplementation of biopls and rater in fiber rich ration on lambs. The assessment on the use of probiotic, which were bioplus and rater on lambs was carried out in two stages, the first stage was selection of the best ration among 12 experimental rations tested in vitro. The second stage was in vivo assessment using 50 rams which were divided into 2 treatments of ration. Treatment 1 (P1) was using the hihgest in vitro dry matter digestibility ration and treatment 2 (P2) was P1supplemented with bioplus and rater. Observation was carried out on daily feed consumption, average dailygains and financial margin. The results showed that ration containing 30% maize cobs, 10% peanut straw and 10% peanut shells, had the highest dry matter digestibility. Supplementation of bioplus and rater, increased daily weight gain (P<0.05) and profit margin calculated as an income over feed cost.

Hasil usaha berupa pedet sapi potong dan pupuk organik. Pendapatan pada usaha pembibitan ternak sapi potong sebesar Rp 3.013.000 (R/C 1,64). Sistem usahatani integrasi padi -ternak sapi potong dengan pola tanam padi -padi -palawija. Kepemilikan lahan 1000 m 2 /peternak dengan 2 ekor induk sapi potong yang dipelihara di kawasan kandang kelompok. Penggunaan sarana produksi berupa bibit 45,83 kg/ha; pupuk 395,52 kg/ha dan tenaga kerja keluarga 43,06 HOK dan tenaga kerja luar keluarga 15,03 HOK setiap musim tanam. Produktivitas lahan gabah kering panen 6,88 ton/ha. Pendapatan usahatani integrasi padi-ternak sapi potong rata-rata sebesar Rp 5.592.310 (R/C 1,82).

The habit of farmers selling crops with a slash system is a practice of buying and selling carried out by wholesalers by buying agricultural products before entering the harvest period. The practice of buying and selling without perfect use sometimes causes the unclear amount of the goods sold, to cause losses to one of the parties. Semi-organic farming is a form of soil processing and crop cultivation by utilizing fertilizers derived from organic materials and chemical fertilizers in minimal quantities to increase the nutrient content of the soil. Semiorganic farming can be said to be environmentally friendly agriculture because it can reduce the use of chemical fertilizers to above 50%. In addition, the application of semi-organic agriculture is sustainable with government programs in sustainable agricultural development. Semi-organic agriculture is also considered to have economic differences such as production costs, revenues, incomes, and profits and feasibility when compared to inorganic agriculture that has been first applied. Based on this concept, the purpose of this study is 1). Know the difference in production, receiving, and income costs from semi-organic and inorganic, 2). Know the difference in profits and business feasibility of a corporate-based slash and weigh marketing system. The determination of samples using the Non-Propositional Stratified Random Sampling method with the number of samples for semi-organic farmers is as many as 20 samples or respondents and inorganic as well as 20 respondents. Quantitative descriptive data analysis as well as a statistical test (independent sample t-test). Analysis of shallot farming with environmentally friendly technology applied by farmers in Nawungan Bantul showed the profit obtained by farmers per hectare of Rp. 129,720,000 within ±50 days (1 shallot growing season) compared to inorganic systems of Rp. 58,430,000. Production reached 15 tons/ha with an average price of Rp 17,000/kg (how to sell weight) with a total receipt of Rp 125,280,000. The average B/C ratio in shallot farmers harvested in a weighted manner of 1.03, greater than the slash of 0.952. The feasibility of semi-organic (environmentally friendly) shallot farming with marketing using corporate institutional innovation (weigh instead of slash) showed the highest figure of 2.03.

Transition of productive irrigated rice fields into other forms makes agricultural sector have to optimized using its field. Purpose of study was to determine application rice-shrimp technology on soil chemical properties, rice productivity, and economical feasibility. Treatments applied were U1 = Control/technology used by local farmers, U2 = Rice-Shrimp cultivation by shrimp population 4,000 tails, U3 = population 6,000, U4 = population 8,000, U5 = Shrimp population 4,000 + rice husk 400 kg, U6 = population 6,000 + husk 400 kg, U7 = population 8,000 + husk 400 kg. The research design was completely randomized block and replicated three times. Results showed number of shrimp populations did not significantly affect to change soil pH, Eh value, level of Fe, and Mg, but had a significant effect on C-organic, N-total, available P and K, CEC. Application of husk as 400 kg and shrimp population up to 6,000 tails had a significantly effect on the number of tillers, grains per panicle, fresh biomass weight, rice yields up to 43.26% and net profit up to 269.14% compared to control by BC and RC ratios are 1.92 and 2.93, respectively while MBCR is 3.34. It means rice-shrimp technology on Bantul classified as feasible.
