Abstract

The mixing process is one of the most important stages in charcoal briquette production because it determines the homogeneity of the mixture, which directly affects the quality of the briquettes. In small and medium-scale industries, the mixing process is generally carried out manually, requiring considerable time, labor, and often producing non-uniform mixtures. This study aims to design and develop a horizontal-type charcoal briquette mixing machine powered by a 6.5 HP gasoline engine with a capacity of 25 kg to improve the effectiveness and efficiency of the mixing process without relying on an electrical power supply. The research method consisted of planning, designing, manufacturing, assembling, and testing the machine. The mixing system employed a gasoline engine, pulley and V-belt transmission, and a gearbox with a reduction ratio of 1:40, resulting in a mixer shaft speed of 33.75 rpm. Performance testing was conducted using three mixing durations, namely 4, 8, and 12 minutes, on a mixture of charcoal powder, rice husk ash, tapioca flour, and water. The results showed that the machine was successfully developed and was capable of mixing 25 kg of briquette material in one operating cycle. A mixing time of 12 minutes produced the most homogeneous mixture with uniform moisture distribution, making it suitable for the briquette molding process. In contrast, mixing durations of 4 and 8 minutes produced less homogeneous mixtures. Based on production capacity calculations, the machine is capable of producing up to 1,000 kg of briquette mixture per day during an 8-hour working period. Therefore, the developed horizontal mixer can improve production efficiency and has significant potential for application in small and medium-scale charcoal briquette industries. Keywords: Charcoal Briquette, Horizontal Mixer, Gasoline Engine, Helical Screw, Mixing Machine, Production Capacity
