Abstract :
Bagasse is the residue from the sugarcane milling process after it is
extracted or the juice is removed in the sugar refining industry so it is called
fibrous waste known as bagasse. Corn cobs are parts of corn that are no longer
used and are a potential biomass waste for making briquettes. This study aims to
make briquettes from corn cobs and bagasse as an environmentally friendly
alternative fuel, to determine the characteristics of biobriquettes from a mixture
of bagasse and corn cobs, including moisture content, ash content, calorific value
and the rate of combustion of biobriquettes. The method used was corn cobs and
bagasse, carbonized for 3 hours, using 80 mesh, 5% tapioca adhesive, printed
using a press with a capacity of 2 tons anddrying briquettes (oven temperature 75 ?
for 3 hours). The test results are compared with SNI 01-6235-2000 for the quality
characteristics of briquettes
In this study, the variation of the biobriquette mixture tested was the ratio
of corn cobs and bagasse = 95%:0%, 70%:25%, 47.5%:47.5%, 25%:70%,
0%:95% . Each was added with tapioca adhesive as much as 5% of the total
weight of the biobriquettes.
The results showed that the best variation was briquettes with a
composition of 25%:70% with the highest calorific value of 6633.26(cal/g) which
was expected, the highest combustion rate was in the variation of 47.5%:47.5%
with a yield of 0. 0.01559(g/min). In another study that the calorific value of
bagasse is low, but in my research that the calorific value of bagasse is high. Of
all the tests carried out, all of them met the quality standards of the briquettes
used, except for the value of the ash content in variations A1,A4,A5 which did not
meet the quality standards of briquettes.
