Abstract

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.

Abstract

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 285°C and in the range of 750-840°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 740°C, there is a tendency to form a single-phase α-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.

Abstract

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.

Abstract

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.

Abstract

Climate change education is crucial for equipping students to tackle pressing global challenges, yet traditional methods often fail to foster critical thinking (CT) and awareness. This study aimed to develop a digital pedagogical model based on climate change issues integrated with Virtual Reality (VR) technology to enhance students' CT and climate change awareness. The research employed a Research and Development (R&D) approach, involving validation, practicality testing, and effectiveness evaluation. Validity data were obtained through expert validation (involving five validators), while practicality and effectiveness data were gathered through implementation processes involving two observers (evaluating model practicality) and 38 high school students (effectiveness test subjects). Implementation utilized a pretest-posttest design and was analyzed descriptively and quantitatively. The findings indicate that the model is valid, with an average validation score of 4.15, and practical, with an implementation score of 4.80 categorized as "very good." The effectiveness test showed significant improvements in students' CT skills, with the average score increasing from the "less critical" to the "moderately critical" category, and in climate change awareness, which rose from the "moderate" to the "high" category. These results highlight the effectiveness of integrating PBL with VR technology in enhancing students’ CT skills and awareness. This study contributes to advancing technology-based education and emphasizes the importance of adopting immersive, problem-based pedagogies in tackling global issues like climate change.

Abstract

Training critical thinking skills in science teacher candidates (STC) faces challenges, particularly due to the ineffectiveness of traditional teaching models, resulting in suboptimal critical thinking performance. This study aims to implement a Hybrid Ethnoscience Project-Based Learning (E-PjBL) model integrated with virtual assistive technology as a solution to enhance critical thinking performance in STC. A mixed-method approach combining quantitative and qualitative methods was utilized. An experimental design involving 51 STC at the University of Mataram was conducted, dividing participants into experimental and control groups. The experimental group engaged in learning activities using the hybrid E-PjBL model, while the control group followed traditional teaching methods. Quantitative data were collected through critical thinking skill tests administered pre- and post-intervention, while qualitative data were obtained from observations of learning implementation. Results demonstrated that the hybrid E-PjBL model significantly enhanced critical thinking skills compared to traditional methods. The experimental group’s posttest scores averaged 4.123, significantly higher than the control group’s 2.667. Statistical analysis using ANOVA revealed substantial differences in critical thinking scores between the groups, with an F-value of 99.613 (p < 0.001) for between-subject effects. Furthermore, a significant interaction was observed between test repetition (pretest-posttest) and group (control vs. experimental), with an F-value of 104.205 (p < 0.001). Qualitative findings indicated the model’s practicality, as evidenced by high student participation and engagement. These findings highlight that integrating ethnoscience, project-based learning, and virtual assistive technology offers an innovative and effective pedagogical approach to enhancing the quality of science teacher education. Further research is needed to explore the model's adaptability across diverse educational contexts.
