Cashew trees have been planted in Indonesia. The yield of these trees has been utilized by many people as snack that is delicious and special, while their skin is often been thrown away, so becoming waste, although they can be utilized. Laka oil (CNSL) is a liquid in cashew skin that has economic value, such as its utilization in glue industry, varnish, synthetic resin, insecticide, fungicide, paint, brake lining and clutch plate.  In this  study , the taking of laka oil from cashew was conducted by using press hydraulic and soxhlet with petroleum ether solution. After obtaining laka oil, Calium Bichromate oxidator was added to improve the quality of laka oil obtained before. Variables studied were the effect of material water content, pressing pressure, the time of pressing on oil weight obtained and the number of Calium Bichromate on oil resin content.   From this study , with material of 100 grams it obtained the best condition on material water content of  7,5 % , pressing pressure of 450 kg/ cm2 , pressing time of 20 minuts, and the oil obtained was 8,5747 grams.
