PENGARUH KOMBINASI LEMAK-METANOL DENGAN RASIO BERBEDA PADA SIFAT-SIFAT PRODUK BIODIESEL BERBAHAN BAKU LEMAK SAPI BALI YANG MENGGUNAKAN KOH SEBAGAI KATALIS
ABSTRACT: The fat (tallow) of
bali cattle is a by-product that have not been used. The fat of cattle lately
has been developed as a raw material for biodiesel. The process of biodiesel
has done through a trans-esterification process and requiring of catalyst. The
ratio of fat-methanol will determine the quality of biodiesel. This study aims
to identify the effect of combination of fatmethanol with different ratios on
the properties of biodiesel products made from fat of bali cattle. The fat of
abdominal of Bali cattle was used as main material. There are three types of
ratios were applied, namely (1:3), (1:5) and (1:7). The study was carried out
experimentally by the reaction esterification and trans-esterification and than
KOH as a catalyst. The results of this study showed that the application of
ratio of fat-methanol different (1:3), (1:5) and (1:7) showed no significant effect
on the value of water content, kinematic viscosity and flash point.
Implementation of ratio of fat-methanol (1:3) can be applied to obtain more
efficient results with properties corresponding to the INS.
