Abstract

Waste candlenut shells are one type of biomass that has significant potential to be developed as an alternative energy source, particularly in the form of briquettes. Candlenut shells, which are typically discarded as agricultural waste, contain combustible material that can be transformed into solid fuel. However, the traditional briquette molding process is still done manually, which is time-consuming, inefficient, and often results in inconsistent briquette shapes and density. This study aims to design and develop a briquette molding machine specifically for processing candlenut shell waste, with the goal of improving both production efficiency and the quality of the briquettes produced. The research methodology includes several stages: mechanical design, selection of appropriate materials, fabrication of machine components, assembly, and performance testing of the machine. The resulting machine utilizes a screw conveyor compression system powered by a 5.5 HP petrol engine. It features a cylindrical mold with a 40 mm diameter to shape the briquettes uniformly. During the performance test, the machine demonstrated a maximum production capacity of 14.3 kg per hour, with an average processing time of 24 minutes and a briquette yield reaching up to 85%. The findings indicate that the machine can significantly streamline the briquette production process while maintaining product consistency and quality. This briquette molding machine is particularly suitable for household and small-scale industries aiming to utilize renewable energy sources and reduce dependency on fossil fuels. The use of this machine also supports environmental sustainability by converting agricultural waste into a usable energy product.
