Due to limitation of resources the availability offossil fuel is become decreasing, an alternative fuel is needed such as Blancoseed before of big potential as source for plantation, the composition of seed kernel hasa high
level of oil (43.3%).Aleurites trisperma
Biodiesel production process was done in the laboratory, its objective to establish the optimum condition. The addition of catalyst H PO (degumming process) of 0,5%, 0,75%, 1%. The esterification treatment use a methanol catalyst mixture of 10%, 15%, 20% with HCl and H SO of 0,5%, 0,75% and 1%. The transestrification treatment use a methanol catalyst mixture of 10%, 15% and 20% with KOH and NaOH of 0,2%, 0,4%, 0,6%. Optimum results will be
34 apllied to biodiesel production in large scale.In making Blanco biodiesel which meet the Indonesian National Standard quality (SNI),Aleurites trisperma chemical used were mixture of methanol 20% (v/v) and catalys NaOH 0.6% (w/v), where resulting in biodiesel with moisture content 0.05 %, acid number 0.76 mg KOH/g, free fatty acid content 0.38 %, density 865 kg/m , kineticviscocity at 40 C of 5.41 mm /s (cSt), base number 101.49 mg KOH/g, alcyl ester content 104.55% massa, iod number 109.73 g I /100 g, cetana number 59,08, and yield of biodiesel oil 79.92 %.24023
