ANALISIS KANDUNGAN AIR SUMBER PAKAN ORANGUTAN KALIMANTAN (Pongo pygmaeus wurmbii) DI STASIUN RISET CABANG PANTI TAMAN NASIONAL GUNUNG PALUNG KALIMANTAN BARAT

Abstract

Water is a very important nutrient for primate health, as it serves as a medium facilitating chemical reactions in the body. The abundance of food sources in forests is one of the things keeping orangutans from extinction. Therefore, it is important to know the proportion of water in the food of orangutans in the forest, their natural environment. Our goal was to define the content of water in the diet of Bornean Orangutan (Pongo pygmaeus wurmbii). The method used in this study is gravimetry, an analysis method based on weight measurements involving the formation, isolation and measurement of the weight of a food ingredient. Results showed the highest water content in the fruits of genus Gironniera 93,634%, and the lowest in the fruits of genus Ficus 38,771%. Based on age and gender, the percentage of consumption of feed water content in orangutans shows that there are differences.Keywords: Analysis of water content, feed, orangutans
