Analisis Pengaruh Pemberian Variasi Kadar Perekat Tapioka terhadap Karakteristik Briket Bioarang Mahkota Nanas

Abstract

As energy sources increase, fossil energy sources decrease, causing the need for energy sources other than fossils. In Indonesia, one of the non-fossil alternative energy sources that is more environmentally friendly is renewable energy.renewable energy), which is abundantly available in the form of agricultural and plantation waste. The use of biomass has been widely used to develop renewable energy. One of the processing of biomass can be used as fuel with a high combustion value such as charcoal briquettes. There are many potential biomass raw materials as materials for making charcoal briquettes, one of which is waste from pineapple fruit. One of the wastes that is often seen in pineapple stalls is the pineapple crown. In the study of making pineapple crown bioarang briquettes, there was a variation of the addition of tapioca adhesive. There were 3 adhesive treatments added, namely 5%, 10% and 15%. The analysis of this study used a one-way ANOVA test to determine the effect of adding tapioca adhesive variations. In the follow-up test using the Tukey test to find out the mean pair of treatments that are significantly different. The results of the analysis carried out in this study showed a significant effect on the values of moisture content, ash content, combustion rate, combustion temperature and firmness. The composition of the best bioarang briquettes in this study was based on the three treatments of adding tapioca flour, namely the lowest water content in treatment A of 3.32%, the lowest ash content in treatment A of 8.49%, the highest calorific value in treatment C of 5468.59 cal /g, the highest burning rate was in treatment C of 0.24 g/minute, the highest burning temperature in treatment C was 189.61 ºC and the highest firmness was in treatment C of 8.82 kg/cm2 .
