ABSTRACT
This study aims to analyze the costs and income of garlic farming, as well as the factors affecting garlic production in Karanganyar Regency. The research was conducted in Tawangmangu and Jatiyoso Districts, involving 110 farmer respondents selected through multi-stage sampling and purposive sampling techniques. Data were analyzed using a quantitative descriptive approach through farm cost analysis and the Cobb–Douglas production function with the assistance of STATA 17 software. The results showed that the average total production cost of garlic farming was IDR 16,198,654 per 0.15 ha, equivalent to IDR 107,991,030 per hectare. The average farmer income was IDR 11,615,087 per 0.15 ha, or IDR 77,433,918 per hectare, while the average profit was IDR 2,675,891 per 0.15 ha, or IDR 17,839,273 per hectare. The results of the Cobb–Douglas analysis indicated that seed, labor, and pesticide inputs had a significant effect on garlic production, whereas land area, manure, and chemical fertilizers did not have a significant effect. The study suggests that proper and efficient management of production inputs can improve the productivity and profitability of garlic farming.
