Abstract

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.
