Abstract

As an environmentally friendly alternative fuel, coconut shell briquettes have the potential to replace fossil fuels. However, the main challenge in its use is the high ash content that reduces combustion efficiency and produces residues that are difficult to clean. This study focuses on analyzing the effect of charcoal particle size on reducing ash content in coconut shell briquettes. The method used was a full factorial experimental design with two process variables: the ratio of charcoal powder and tapioca starch (90%:10%, 85%:15%, 80%:20%), and charcoal particle size (40, 60, and 80 Mesh). To improve accuracy, each treatment combination was repeated three times. The stages of making briquettes include material preparation, mixing, molding, and drying. Ash content testing was conducted in accordance with SNI 01-6235-2000 standard. The results showed that charcoal particle size has a significant effect on ash content, where larger particles produce lower ash content. The lowest ash content, 1.49%, was found in briquettes with 40 Mesh particle size. This study makes an important contribution to the development of more efficient and environmentally friendly coconut shell briquettes.

Abstract

Binder is a crucial component in briquette production, serving to consolidate charcoal particles into a solid form. This study aims to analyze the effect of tapioca starch concentration as a binder on the reduction of ash content in coconut shell briquettes. The binder concentrations used were 10%, 15%, and 20% of the total material mixture, with ash content testing conducted according to SNI 01-6235-2000 standards. The briquette production process included raw material preparation, mixing, molding, and drying. The results showed that binder concentration significantly affected the briquette's ash content. Lower binder concentrations resulted in reduced ash content, with the optimal ash content of 1.52% achieved at a 10% binder concentration. Excess binder tended to increase ash content due to residual binder that did not fully combust. These findings highlight the importance of controlling binder concentration to improve the quality of coconut shell briquettes as an alternative fuel source.

Abstract

Binders play a vital role in briquette production by uniting charcoal particles into a solid form. This study aims to evaluate the effect of tapioca starch concentration as a binder on reducing the ash content of coconut shell briquettes. The binder concentrations used were 10%, 15%, and 20% of the total material mixture, with ash content testing conducted according to SNI 01-6235-2000 standards. The briquette production process involved raw material preparation, mixing, molding, and drying. The results indicated that binder concentration significantly influenced the ash content of the briquettes. Lower binder concentrations resulted in reduced ash content, with the lowest ash content of 1.52% achieved at a binder concentration of 10%. Conversely, higher binder concentrations tended to increase ash content due to residual binder that did not fully combust. This study emphasizes the importance of regulating binder concentration to enhance the quality of coconut shell briquettes as an alternative fuel source.
