Ukuran Partikel Dan Waktu Kontak Karbon Aktif Dari Kulit Singkong Terhadap Mutu Minyak Jelantah

The purpose of this research was to know the effect of particle size and contact
time of actived carbon from cassava skin on quality and sensory characteristics of
used cooking oil. This research was conducted experimentally method by using a
completely randomized design (RAL) factorial with three repetitions. The first
treatment factor was particle size of actived carbon such as A1 (60 mesh) and A2
(100 mesh). The second factor was contact time of actived carbon such as B1 (2
hour), B2 (4 hour), and B3 (6 hour). Data obtained were statistically analyzed by
using Analysis of Variance and continued with Duncan’s New Multiple Range Test at
5% level. The results showed that particle size of actived carbon from cassava skin
significantly affected moisture content, peroxide number, free fatty acid, and sensory
test of clarity. Contact time of actived carbon significantly affected moisture content,
peroxide number, free fatty acid, density, sensory test of colour and flavour of used
cooking oil. The interaction between these two factors significantly affected moisture
content, peroxide number, free fatty acid, density, and sensory test of colour and
flavour of used cooking oil. The best treatment in this research was A2B3 (100 mesh
particle size with 6 hour contact time) with moisture content of 0.35%, peroxide
number of 0.59 meq/kg, free fatty acid of 1.64%, and density of 0.88 g/L. The results
of descriptive test on the fruit leather showed that the used cooking oil had brownish
yellow color (1.56), a little rancid scented (1.70), clear (3.70) and overall assessment
hedonically was rather not favored by panelists.
