Karakteristik Briket Dengan Pencampuran Kulit Batang Sagu Dan Tempurung Kelapa
Sago stem bark and coconut shell contain lignin and cellulose compounds
which are quite high and have not been utilized optimally. Therefore this study
aimed to obtain the best formulation of the sago stem bark and coconut shell as
the main ingredients in making good quality briquette. The research was carried
out experimentally using the Completely Randomized Design (CDR) method with
5 treatments and 3 replications. The treatments in this study were P1(rasio of
sago bark charcoal and coconut shell charcoal 90:10), P2(of sago bark charcoal
and coconut shell charcoal 80:20), P3 (of sago bark charcoal and coconut shell
charcoal 70:30), P4 (of sago bark charcoal and coconut shell charcoal 60:40), P5
(of sago bark charcoal and coconut shell charcoal 50:50). Data obtained were
statically analyzed by analysis of variance (ANOVA) and continued with
Duncan’s New Multiple Range Test (DNMRT) at level 5%. The results show that
the ratio of sago stem bark and coconut shells did not significantly affect
moisture, ash and bound carbon contents as well as density, heating value, volatile
matter levels and fuel power. The best treatment was P5 (rasio of sago bark
charcoal and coconut shell charcoal 50:50) with moisture content 3.67%, ash
power 4.54%, volatile matter 1.13%, density power 0.67 g/cm3, bound carbon
90,68%, calorific value 7748.62 cal/g and fuel power 0.0029 g/second.
