Proboscis monkey (Nasalis larvatus) is a type of primate that is selective for its food. They choose food sources according to the nutrients their bodies need. When food sources are running low, proboscis monkeys will look for other low-nutrient food sources to eat. This research aims to analyze the nutrition of proboscis monkey feed sources in Bakut Island Nature Park. The data collection technique used a test sampling method in the field in the form of plant parts eaten by proboscis monkeys. Then the sample material was brought to the laboratory for proximate analysis to determine the content of water, ash, crude protein, crude fat, crude fiber, and carbohydrates. The results showed that there were eight vegetations that became the source of proboscis monkey's food. The composition of the feed that consumed the most was leaf shoots with 80% and fruit with 20%. The proximate test results show that the water content is the parameter that has the highest valuofom the other parameters in the entire sample. Tambal Ulang has the highest water content, which is 78.05%. The highest carbohydrate content was found in banyan leaves at 42.88%, the highest protein content was in hibiscus leaves at 6.94%. Banyan leaves have the highest crude fiber content of 8.33%. The highest ash content was hibiscus leavat of 4.61%. Ketapang leaves have the highest fat content of 0.61%.
