The Study on Biomass Production from Hyacinths Mixed with Mangosteen Peel

Abstract

The purpose of producing biomass from water hyacinth is to study its physical characteristics, thermal properties, and economic worthiness if used in business from hyacinths mixed with mangosteen peel. In the production process, the diameter is 4 mm, and the length of the biomass sticks is between 10-50 mm. In the production of biomass from water hyacinth, there are two formulas: the formula without mixed mangosteen charcoal powder and the formula with mixed mangosteen charcoal powder. The mixing ratio is 1:4. From the calorific value test, it was found that the dried biomass without mixed charcoal powder provided the highest calorific value of 5,102.21 cal/g. From the strength test, the dried biomass without mixed charcoal powder had the highest strength, which was 10 kg/cm². The ignition time test of the dried biomass mixed with charcoal powder showed the longest ignition time, which was 53.47 minutes. The ignition temperature test of the dried biomass without mixed charcoal powder had the highest value, which was 99 degrees Celsius. From the ash content analysis, the dried biomass without mixed charcoal powder had the lowest ash content, which was 5.23%. The economic feasibility analysis indicated that the payback period was 5 years, 7 months, and 20 days.
