| dc.description.abstract | The purpose of this research was to know the effect of addition of adsorbent
(zeolite active and arang active) and mixing temperature to the quality of purified
jelantah oil. The research was performed using factorial completely randomized design
with two factors. The first factor was comparison of zeolite active with charcoal active
(A) consisted of A1 = 20%:80%, A2 = 40%:60%, A3 = 60%;40%, A4= 80%:20%. The
second factor was mixing temperature (T) consisted of T1 = 80oC, T2 = 90oC, T3 = 100oC,
T4 = 110oC. Parameters observed were water content, dirty content, free fatty acid
content, peroxide value, colour index value, viscosity, organoleptic value of warna and
aroma. The result showed that comparison of zeolite active with charcoal active gave
highly significant effect on water content, dirty content, free fatty acid content,
organoleptic value (warna). Mixing temperature gave highly significant effect on water
content, dirty content, free fatty acid content, peroxide value, viscosity, and organoleptic
value (warna and aroma) of purified jelantah oil. The interaction between comparison of
zeolite active with charcoal and mixing temperature gave highly significant effect on
water content, and gave not significant effect on dirty content, peroxide acid, viscosity,
and organoleptic value (warna and aroma) of purified jelantah oil. Comparison of
zeolite active with charcoal active with concentration 20%:80% and mixing temperature
90oC gave the best quality. | en_US |
