As catch fisheries have experienced overfishing symptoms, which resulted in a decrease in fish resources, the government must develop freshwater aquaculture. Sleman Regency has known for its growing freshwater aquaculture development, which supplies about 70% of the total fish production in Yogyakarta Special Province. Despite the rising demand for fish consumption, fish cultivators face problems in the capital, infrastructure, weak bargaining power, quality problems, and long distribution chains. One way to overcome these problems is to strengthen the bargaining position through the fish farmer groups. This study aims to analyze the financial feasibility of gourami farming, whose owners are members of business associations. In the business association, fish farmers agree to collaborate in running their business to cultivate gourami in a supply chain process ranging from production to marketing. The collaboration of fish farmers integrates four segments of the fish-raising chain system, consist of seedling handling from 0 to1.5 months old, raising fish from 1.5-to 3.5 months, from 3.5 to 6.5 months, and 6.5 to 12 months. Using a quantitative research method, this study analyzes 40 fish farmers in Seyegan, Sleman District of Yogyakarta. The financial feasibility analysis uses the net present value, benefit-cost ratio, internal rate of return, and break-even point. Results of these analyzes indicate that financially, the collaborative gourami farming in Seyegan District is feasible with an NPV of segment I is Rp 11,122,952.00, of segment II, is Rp 2,174,940.00, of segment III, is Rp 9,748,705.00. Of the segment, IV is Rp 18,691,435,86. The B/C Ratio for segment I is 1.87, segment II is 1.55, segment III is 2.13, and segment IV 2.05. The BEP value for segment I is Rp 1,709,228.00, for segment II is Rp 1,779,290.00, for segment III is Rp 852,100.00, and for segment IV is Rp 2,000,672.00.

Sweet potato production in Indonesia is spread across several provinces, including Central Java, with a harvest area of 6,348 hectares (ha), production of 145,068 tonnes, and productivity of 228.51 quintals (Ku)/ha. One of the regencies with the largest harvest area is the Karanganyar Regency, with a harvest area of 868 hectares. This present study aims to analyze the cost, revenue, income, profit, and profitability of sweet potato farming in Karanganyar Regency. Besides, the study also analyses the efficiency of farming. In this study, the analysis of sweet potato farming costs is calculated using explicit costs and implicit costs. Implicit costs include the cost of seeds and labor in the family. The explicit costs include labor outside the family, fertilizer, pesticides, taxes, equipment depreciation, and own capital interest. Forty sweet potato farmers located in Tawangmangu and Ngargoyoso District, Karanganyar, were used as samples. The sample utilizes a simple random sampling method. The data analysis used is the analysis of costs, revenues, income, profits, efficiency, profitability. Data was obtained from an interview and questionnaire to the respondents. Results of descriptive statistics indicate that the revenue received is IDR 99,488,080 per hectare, while the explicit and implicit costs are IDR 8,068,714 per hectare and IDR 26,906,990 per hectare, respectively. The farming generates income IDR 91,419,366 per hectare and obtains a profit of IDR 64,512. 376 per hectare. Sweet potato farming is classified as efficient and profitable with an efficiency value of 2.8 per hectare and a profitability value of 1.8.

Indonesia produces large amounts of rice. However, almost every year, rice imports are still carried out to meet the needs of food stock, and supply in several regions still needs to catch up to demand. The application of rice cultivation technology contributes to increasing the productivity of cultivated rice products with the “Jajar Legowo System” (JLS). The purpose of this study is to compare the income of JLS cultivation and conventional systems (CS). This research applied the descriptive-analytic method from the survey. The purposive method was applied deliberately in determining the location of the study by considering certain objectives. This study uses a simple random sampling techniques to collect samples from 30 JLS and CS farmers. The collected data is first compiled, described, and then analyzed by quantitative research methods, namely, taking a sample from a population using a questionnaire as a data tool. The research results showed that the application of JLS rice cultivation technology significantly increased productivity (13.62%), income (29.88%), efficiency (18.90%), and benefits for rice farmers (8.53%) compared to that CS. Rice cultivation using JLS is appropriate in Indonesia to increase farmers’ income. The application of JLS can improve farmers’ income. This technology is feasible to develop in Indonesia.
