Data collection is done through FGD, observation, and documentation. Farmer's profile analysis using quantitative descriptive methods consists of frequency, percentage, mean, and standard deviation. Economic calculations include production costs, revenues, revenue contributions, and multiple regression analysis to see the factors that affect the contribution of pig farm income. The results showed that the average production cost (Explicit+Implicit) was IDR 15,518,956.72/year. Average fixed costs IDR 12,684,060.17/year (81.73%).
