Analysis of income and risks of potato farming in the highlands of Wonosobo Regency, Central Java, Indonesia

Potatoes serve as a leading horticultural commodity in Wonosobo, boasting high economic value and significant market opportunities both nationally and internationally. Climatic conditions in highland such as strong winds, low temperatures, and high humidity threaten potato production stability. Climate-related disturbances encourage the emergence of pests and fungal diseases, especially during prolonged rainy periods resulting farmers facing higher yield volatility. The research aims to analyse production and income risks, net revenue, and feasibility of potato farming. The study was conducted purposively in Wonosobo Regency, based on consideration that most of population works as farmers and relies on potatoes as their primary crop. A total of 40 potato farmers were selected randomly as respondents. Production and income risk were analysed using Coefficient of Variation, while farming feasibility was assessed based on Revenue-Cost Ratio, labour productivity, and capital productivity. The results revealed that production and income risk of potatoes fell into high category. The income from potato farming on 2,533 m² of land was IDR 36,140,995. Potato farming was feasible based on revenue cost ratio, labour productivity, and capital productivity. Farmers have been advised to utilize windbreaks, selecting seed varieties tolerant to highland environments, and enhancing irrigation management for sustainable potato farming.
