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 andnot easily break. It is affected by the concentration of adhesives used. The raw materials ofadhesive used so far are still consumed by the public such as starch and sago. Therefore, it isnecessary to conduct research to find alternative sources of adhesives that are relatively incompetition with human food needs. The raw material used in the manufacture of adhesives isstarch from banana weevil waste. This study aims to find out the quality of sawdust briquetteswith banana weevil starch as adhesive and to know the ability of banana weevil starch to be asan adhesive. The research method used is an experimental method by doing variations in adhesiveconcentrations of 20, 30 and 40%. Particle size of sawdust used is 20 mesh with compressedstrength of 100 kg/cm2 for 2 minutes. The observed parameters are heat value, water content, ashcontent, density, strong press, split index, and burn test. The results showed that the best calorificvalues, water content and ash content were produced at 20% consecutive adhesive concentrationsof 4515 cal/gram, 6.95%, and 2.37%. Density, strong press, split index and best light durationare 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 of30%. Briquettes with adhesive from banana weevil starch have good briquette quality.
