PRODUKSI BIODIESEL DARI MINYAK JELANTAH MENGGUNAKAN KATALIS HETEROGEN CANGKANG BEKICOT (ACHATINA FULICA) DENGAN METODE PENCUCIAN DRY WASHING
Abstract: Biodiesel is an
alternative fuel from renewable sources with the composition of fatty acids
from vegetable oils or animal oils. Biodiesel production from used cooking oil
was counducted to determine the effect of basa heterogen catalyst of snail
shell that used on a transesterification reaction with dry washing method for
the yield and quality of biodiesel based on the quality standard of Biodiesel
according to SNI No. 04 – 7182-2006. The study was designed using Rancang Acak
Lengkap (RAL) with two factors, the concentration of catalyst (K): (6, 7 and
8%) and the concentration of magnesium silicate (M): (1 and 1.5%). The
parameters analyzed include biodiesel yield, viscosity, density, acid number,
flash point, cloud point , water content and heat value. The results showed
that the highest yield of 63% was obtained from treatment of the catalyst
concentration 6% and magnesium silicate 1% with the quality of biodiesel:
viscosity of 5.692 mm2 / s, density of 867.8 kg / m3, the number of acid 0.605
Mg-KOH/Kg, a flash point of 160 oC, 12 oC cloud point, the water content of
0.08% and a heat value of 41.379 MJ / Kg.
