THE EFFECT OF UV LIGHT ON THE YIELD AND CHARACTERISTICS OF BIODIESEL FROM CANDLENUT OIL USING A TiO2-K2O/NATURAL ZEOLITE COMPOSITE

This study examines the effect of UV irradiation on yield and physical characteristics biodiesel from candlenut oil using a TiO 2 -K O/natural zeolite composite. Natural was activated with KOH impregnated . The formed composite analyzed an X-ray diffractometer. Biodiesel synthesized to methanol molar ratio catalyst loading (w/w oil) 1:4, 1:6, 1:8, 2, 4, 6%, respectively. XRD analysis shows peak patterns anatase rutile , K O, zeolite. light can increase yield, highest at 82.08% 1:8 2%. properties are in accordance national standard SNI 7182:2015. GCMS results that main components fatty acid methyl ester oleate, palmitate, linoleate.
