| Summary: | Durian seed has potency as an adhesive, because it has a low amylose
content. In making biobriquette, the more adhesive content results in lower
heating value. Durian peel and coconut shell are wastes that have potency as raw
materials for biobriquette production. The heat value of charcoal can fulfill
according to the standard value. The aim of the study is to evaluate potency of
starch from durian seed as an adhesive biobriquette from durian peel and coconut
shell waste.
This research was tested the amylose content, shear strength and viscosity
to determine the potency of starch from durian seed as an adhesive. The variation
of biobriquette process from starch from durian seed as an adhesive are 4%, 6%,
8%, 10%, 12% and 14%. Further, in this research testing on biobriquette
including density, compressive strength, shatter test, moisture content, ash
content, volatile matter content , fixed carbon content, and heat value.
The test result was showed that the starch from durian seed has the
potency as an adhesive better than the starch from cassava. Starch from durian
seed has the amylose content of 15,0880% (which the starch from cassava is
17%), the shear strength of 2,7 kg/cm2 (which the starch from cassava is 1,3333
kg/cm2), and the viscosity of durian seed is 38,8333 d.Pa. (which the starch from
cassava is 408,3333 d.Pa.). Biobriquette with adhesive of the starch from durian
seed have better quality than the starch from cassava 10% on the characteristic
density (6% -14%), Shatter test (10% -14%), water content (4% -8%), ash content
(12% -14%), volatile matter (4% -8%), fixed carbon (4% -6%), and heat value
(4% -6%). Biobriquette has a water content, volatile matter, and heat value that
fulfill the standard from SNI 01-6235-2000, and the value of density, compressive
strength, shatter test, fixed carbon that fulfill according to the standard. The ash
content of biobriquette influenced by charcoal composition, the composition of
charcoal test 75%: 25% with adhesive from the starch from durian seed 10% has
the ash content of 5.9553%, it fulfill according to the standards. The best adhesive
content in biobriquette is 4%. Biobriquette has a characteristic density of
0,5468% |
