      Historically, Indonesia had lots of coconut tree (Cocos nucifera) spreading almost all of the thousand islands, with famously named as ‘negeri nyiur melambai’. Before the year of 1970-iest, in Indonesia, the people used coconut oil as the one of oil for frying foods. The people planted coconut tree intensively. Yet, after the year of 1970-iest, some new verieties of palm tree was introduced then the palm trees were planted extensively and intensively, the coconut oil was almost extinguished since then. Mostly now people use palm oil as frying oil. The use of coconut products now are only limited to meat and water of young coconut fruit and as some parts of food sauces. So, population of coconut tree is now drastically decreased. In this research was to study the possibility of prospective material of coconut oil as other than frying oil such as first-generation biodiesel feedstock. In the study, coconut oils were extracted through dry method and wet method. The coconut oil also was extracted through soxhlet method as reference of total coconut oil. Parameters used in the study were yield, relative density, iodine value, and saponification number. The data showed that coconut oil extracted through dry method has yield of 22,12%, relative density of 0,915 (40oC/water 20oC), iodine value of 8,5 wisj, and saponification number of 260 mg KOH/g oil. And, coconut oil extracted through wet method has a yield of 23,67%, relative density of 905 (40oC/water 20oC), iodine value of 7,5 wisj, and saponification number of 250 mg KOH/g oil
