Certified rice seeds can increase productivity, but only 53% of farmers use them in Indonesia. Rainfed paddy fields with certified seeds have the potential to increase productivity and develop into production centers. The research aimed to describe farmers’ knowledge of certified rice seeds, analyze their suitability in terms of performance and importance, and analyze farmers’ satisfaction with certified rice seeds. The research was carried out in 2021 in Banjarejo Village, Bayan District, Purworejo Regency, Central Java Province. Sampling was carried out by a purposive random sample of 31 farmers. The sampling techniques were carried out using purposive random sampling. The Customer Satisfaction Index (CSI) and Importance Performance Analysis (IPA) were analyzed descriptively and quantitatively. The results showed that most farmers use certified rice seeds after 3-4 planting seasons. Internal factors and economic factors affect the use of certified rice seeds. Farmers’ CSI value of seed attributes amounted to 71.05%. The use of certified rice seeds in rainfed paddy fields must be increased using a persuasive seed-independent village area approach.
