Abstract

Rice husk is an agricultural waste that is still underutilized, even though it has great potential as a raw material for making charcoal briquettes. This study aims to examine the potential for utilizing rice husk as charcoal briquettes and to educate the people of Kertamulya Village about the manufacturing techniques. The method used in this study is a descriptive method with a socialization approach and direct training to the local community. The briquette making process involves several stages, namely burning the husk using the pyrolysis method, mixing with natural adhesives, molding, and drying. The results of the experiment showed that the composition of the mixture of materials and the right drying method greatly affect the quality of the briquettes produced. Briquettes with a ratio of 100 grams of starch, 1 kg of charcoal powder, and 400 ml of hot water gave the best results with stable combustion and long-lasting embers. In addition to contributing to reducing agricultural waste, this innovation also has economic value by opening up business opportunities for the community. Therefore, the use of rice husk as charcoal briquettes can be an environmentally friendly and sustainable alternative solution in supporting energy security and the welfare of rural communities.

Abstract

Traffic accidents involving four-wheeled vehicles constitute a complex problem influenced by multiple factors, including vehicle speed and traffic density. Accurate accident-risk assessment is essential to support preventive and control efforts on road networks. This study aims to design and implement an accident-risk evaluation model based on a Mamdani-type Fuzzy Inference System (FIS) to accommodate uncertainty in decision-making. The research procedure includes identifying input and output variables, constructing membership functions, fuzzification, formulating fuzzy rules, and performing inference and defuzzification. Testing results indicate that, for a combination of 80 km/h speed and 70 vehicles/km density, the centroid defuzzification method yields a risk value of 25.31%. This value falls within the low-to-moderate risk category. These findings suggest that the developed Mamdani FIS model is effective as a methodological approach for accident-risk evaluation.
