Abstract

Indonesia is a country rich with the natural resources. One of them is rubber plant. Beside latex as its main product, rubber tree also produces rubber seed. Rubber seed contains rubber seed oil. In the oil extraction process using mechanical methods, around 30% rendemen is obtain, while the oil content in the rubber seed is around 50 – 60%. Thus, the oil content remained in the waste rubber seed is still plentiful. The oil taking process from the waste rubber seed is done by soxhletation and extraction using strirring. The purpose of this research is to compare the extraction methods of waste rubber seed oil with solvent by soxhletation and extraction solvent by stirring with several solvents to get the most rubber seed waste oil, as well as to analyze the chemical physical properties of waste rubber seed oil. In this research, the yield of the soxhletation result with the same solvent was obtained more than the one with exctration by stirring. The most yield is obtained from the extraction by soxhletation with n-hexane with 30 times of total circulation with the result 19.80 % and the oil chemical physical properties among others viscosity 59.4358 cp, Spesific gravity 0.9324, refractive index 1.583, iodine numbers 179.1730 mg/g, saponification number 172.1848 mgKOH/g, acid number 37.8267 mg/g
