Analysis of The Quality of Sawdust Briquettes With Adhesive Banana Starch Flour (Musa paradisiaca L.)

Abstract

The good quality of briquettes characteristics is to have a high calorific value and strength and
not easily break. It is affected by the concentration of adhesives used. The raw materials of
adhesive used so far are still consumed by the public such as starch and sago. Therefore, it is
necessary to conduct research to find alternative sources of adhesives that are relatively in
competition with human food needs. The raw material used in the manufacture of adhesives is
starch from banana weevil waste. This study aims to find out the quality of sawdust briquettes
with banana weevil starch as adhesive and to know the ability of banana weevil starch to be as
an adhesive. The research method used is an experimental method by doing variations in adhesive
concentrations of 20, 30 and 40%. Particle size of sawdust used is 20 mesh with compressed
strength of 100 kg/cm2 for 2 minutes. The observed parameters are heat value, water content, ash
content, density, strong press, split index, and burn test. The results showed that the best calorific
values, water content and ash content were produced at 20% consecutive adhesive concentrations
of 4515 cal/gram, 6.95%, and 2.37%. Density, strong press, split index and best light duration
are produced at 40% consecutive adhesive concentrations of 0.30 gr/cm3,21.44 kg/cm2, 0.02%,
and 349 seconds. As well as the best embers for 3384 seconds at an adhesive concentration of
30%. Briquettes with adhesive from banana weevil starch have good briquette quality.
