Rice husk briquettes have great potential to be developed as an alternative energy source. The characteristics of briquettes are divided into physical characteristics and chemical characteristics. In the process of making briquettes, an adhesive is needed. Taro has a high starch content, ranging from 70-80%. Therefore, taro starch can be used as an alternative to briquette adhesive. The purpose of this study was to analyze the quality of rice husk briquettes for the variation of the adhesive and to analyze the effect of variations in the amount of adhesive on the calorific value of the briquettes. In this research, an analysis of the physical characteristics of the briquettes (ash content, moisture content, volatile matter, and fixed carbon) and the chemical characteristics of the briquettes (calorific value) was carried out. The results of the study showed that the characteristics of the briquettes met the SNI quality standards for water content, fixed carbon, and ash content for briquettes with taro starch adhesive concentrations of 5% and 10%, but did not meet the SNI quality standards for volatile matter, calorific value, and ash content with an adhesive concentration of 15%. Briquettes with a 5% adhesive percentage have a highest calorific value of 4245.7 Cal/g but do not exceed SNI quality criteria. © 2025 Author(s).
