This study explores the role of the Begarap tradition in shaping character and maintaining social integrity within the Sasak community in Lombok. The primary objective is to understand how Begarap functions as a conflict resolution mechanism and social control tool in the face of modernization challenges. The research employs a qualitative approach, combining literature studies and in-depth interviews with traditional and religious leaders in Pujut and Praya Timur. The findings reveal that Begarap remains relevant in upholding values of honesty and social responsibility. This ritual carries strong spiritual elements, where individuals swear an oath using sacred water from Nyatuq’s grave. The belief in supernatural consequences enhances its effectiveness in regulating behavior. Despite social transformations due to globalization, Begarap endures as a symbol of cultural and religious identity. The study concludes that Begarap contributes significantly to maintaining social stability and reinforcing moral values within the Sasak community. Recommendations include integrating Begarap’s values into education and promoting its preservation through documentation and further research to ensure its relevance in the modern era.

Barium hexaferrite (BaFe12O19) is a material of significant interest due to its wide range of applications. In this study, we synthesized barium M-hexaferrites (BaFe12-2xCoxZnxO19) powders through the co-precipitation method, starting from BaCO3 and FeCl3.6H2O powders, with Co and Zn powders used as dopant materials. The variations in x values were set at 0, 0.2, 0.4, 0.6, 0.8, and 1. Our findings indicate that the co-precipitation method is highly effective for synthesizing barium M-hexaferrites (BaFe12-2xCoxZnxO19) nanomaterials, which contain more than 89% iron elements and have an average particle size of 50 nm. The Differential Thermal Analysis (DTA) and Thermogravimetric Analysis (TGA) reveal that phase transformations occur at temperatures of 285Â°C and in the range of 750-840Â°C. Further analysis using the Rietveld refinement method demonstrates that the barium M-hexaferrite phase begins to form at relatively low temperatures, with the most optimal yield observed at x = 0.4. At temperatures exceeding 740Â°C, there is a tendency to form a single-phase Î±-Fe2O3 (hematite). The introduction of Co and Zn as dopant ions results in only minor changes to the lattice parameters of the basic hexagonal crystal structure. This comprehensive study underscores the viability of the co-precipitation method for producing high-quality barium M-hexaferrites and provides valuable insights into the effects of Co and Zn doping on the structural and thermal properties of these materials.

This study investigates the effects of varying base materials, specifically coconut shell charcoal (ATK) and corncob charcoal (ABJ), on the characteristics of biobriquettes. The research employs an experimental method, analyzing the impact of different ATK and ABJ proportions on calorific value, ash content, moisture content, density, and combustion rate. The biobriquettes were produced by mixing coconut shell and corncob charcoal with 10% tapioca starch adhesive, molded into cubes, and dried. The results show that increasing the ATK proportion improves the calorific value, with the highest value of 10,640 calories in briquettes with 90% ATK. In contrast, higher ABJ content results in faster combustion rates but lower energy efficiency, with the lowest calorific value of 6,424 calories in briquettes containing 90% ABJ. The study also highlights that all biobriquettes meet Indonesian National Standards (SNI) for moisture content and calorific value, although only the 90% ATK sample meets the ash content standard. These findings suggest that coconut shell charcoal is a superior biomass material for producing high-performance biobriquettes, with a 90% ATK and 10% adhesive combination yielding the best overall results for sustainable energy applications.

This research focuses on optimizing the binder percentage in organic waste-based briquettes to improve their calorific value and combustion rate. Conducted through experimental methods, organic waste such as sawdust, dry leaves, and branches were processed into briquettes using varying concentrations of tapioca starch as a binder (10%, 12.5%, 15%, and 17.5%). The experiment evaluated key performance metrics, including calorific value, combustion rate, moisture content, ash content, and briquette density. Results showed that the optimal calorific value (9,234 cal/g) was achieved with 10% binder, while the highest combustion rate (0.586 g/min) occurred at 15% binder concentration. These findings suggest that lower binder percentages result in higher energy efficiency, while higher binder content prolongs combustion. However, increased binder content also led to higher ash production, with the highest ash content recorded at 17.5% binder. The research highlights that balancing the binder ratio is essential for creating briquettes that are both energy-efficient and environmentally sustainable, offering a viable alternative to traditional fuels in Indonesia's pursuit of renewable energy solutions.
