Abstract. Oyster mushroom cultivation is best done in the highlands, while Bantul Regency is included in the lowlands with an altitude of 0 – 500 meters above sea level with an average annual temperature of 300 C. Climate change is causing the development of oyster mushrooms farming
in the lowlands requires special treatment in the production process. This study aims to analyze the costs, income, profits, and feasibility of oyster mushroom farming in Bantul Regency. The determination of the location of the study was done purposively. The respondents were determined using the census method according to bag logs ownership. A total of 21 farmer respondents were classified into three groups, namely Group 1 (farmers own < 1,000 bag logs), Group 2 (1,001-3,000 bag logs), and Group 3 (> 3,000 bag logs). The feasibility of oyster mushroom farming was analyzed using Revenue Cost Ratio (R/C), capital and labour productivity, respectively. The results showed farmers in group 3 had the largest revenue, income
and profit. Oyster mushroom farming is feasible because the R/C >1, capital productivity > capital interest, and labor productivity > labor wages. Bantul Regency has the potential to develop oyster mushrooms even though it is located in the lowlands.
