INVESTIGATION ON BIOMASS BRIQUETTE FROM Cerbera manghas WASTE TWIGS AS RENEWABLEENERGY SOURCE

Indonesia is a tropical nation that has numerous assortments of plants. However, these resources have not been utilized perfectly as assets. One of the plants that are frequently seen in Indonesia is Cerberamanghas. Cerberamanghas is known as one of the trees that have strong roots and it is generally utilized for greening in Surabaya. Although used as shading trees and to decrease air contamination in urban regions, squanders from the twigs of this plant turn into a significant issue for the cleanliness of the city. To tackle this problem, the waste from the falling twigs can be utilized as briquettes when handled well. This study intended to research the capability of Cerberamanghas twigs wastes to be utilized as biomass briquettes and also to assess the properties of the briquettes. The proximate and ultimate analysis examinations were conducted to obtain the property of the briquettes. The influence of tapioca percentage in briquette to the calorific value of the biomass briquettes was also obtained in this study. Calorific values of five blends with different tapioca mixtures of 10%, 20%, 30%, 40%, and 50% were assessed by using oxygen bomb calorimeter. The outcomes of the study suggest that the biomass briquettes made of waste Cerberamanghas twigs can be made by utilizing tapioca as a binder. The more prominent the rate of the mass of tapioca in the briquettes, the lower calorific value obtained in briquette. Biomass briquettes made of waste Cerberamanghas twigs can be made into a source of manageable energy with the ideal mixtures of 90% Cerberamanghas waste twigs and 10% tapioca
