Pig fodder competes with human needs, one of which is chayote, which is abundantly available during the harvest season and even becomes waste. Therefore, in order to maintain the nutritional content and increase the shelf life so that it can be used when there is a shortage of feed, fermentation is carried out using dissolved carbohydrates, namely rice bran. The aim of the research was to examine the nutrient, mineral, and digestibility of dry matter and the organic matter digestibility of chayote due to the addition of rice bran levels in the fermentation process. Research using a completely randomized design (CRD) with 4 treatments and 5 replications consisting of rb0: chayote without rice bran, rb5: chayote + 5% rice bran, rb10: chayote + 10% rice bran, and rb15: chayote + 15% rice bran. Parameters observed were the content of nutrients, minerals, and digestibility of dry matter and organic matter. The analysis used one-way analysis of variance and The Duncan multiple range test (DMRT). The results showed that increasing the addition of rice bran up to 15% caused a decrease in water content, organic matter (BO), non-nitrogen extract material (NNEM), Ca, K, digestibility of dry matter and organic matter, and the use of the best rice bran in chayote fruit fermentation is 5%. It was concluded that the use of rice bran levels in chayote fruit fermentation affected the nutrient, mineral, and digestibility of dry matter and organic matter, and the best level was 5%.
