Abstract

LaNi5 is widely used in various applications. Many methods to produce LaNi5 particles have been reported but information for the large-scale production, so far, is less available. This study aimed to evaluate the project for the production of LaNi5 particles using combustion-reduction (CR) and co-precipitation-reduction (CPR) methods based on engineering and economic perspective. Engineering evaluation was conducted by evaluating the CR and CPR processes from stoichiometry. For the economic evaluation, several economic parameters were calculated in the ideal condition including gross profit margin (GPM), payback period (PBP), break-even point (BEP), cumulative net present value (CNPV), profitability index (PI), internal rate return (IRR), and return on investment (ROI). For the worst cases in the project, it was done by calculating both the internal problems (i.e., raw materials, sales, utility, labor, employee, fixed cost, variable cost, and production capacity) and the external issues (i.e., taxes and subsidiaries). The engineering analysis provided the information that CR and CPR projects are prospective for being able to be done using commercial apparatuses. The economic analysis from GPM, PBP, BEP, CNPV, and PI showed the positive results, while IRR and ROI showed the negative ones, indicating that the projects are acceptable for large-scale production, but it seems to be less attractive for industrial investors. The analysis also confirmed that the CR process was more prospective than the CPR process. This work has demonstrated the important of the projects for further developments.

Abstract

Education in Indonesia continues to face challenges, particularly the mismatch between graduates’ skills and labor market demands, alongside increasing social and moral issues. This study seeks to integrate Paulo Freire’s principles of conscientization, humanization, and dialogue with Islamic values of social justice, drawing on the hadith concerning the liberation of Badr War prisoners as a conceptual basis. Using a qualitative approach, the research applies content analysis of Freire’s works and classical hadith sources, supported by field studies at SMK Syahida Tasikmalaya. Findings show that the application of this transformative model in vocational schools encourages active student participation through critical discussions, social reflection, and contextual learning relevant to daily realities, including skills that strengthen family economies. Teachers report that the model assists in adapting lessons to students’ needs, particularly for those who lag behind, though challenges remain in administrative burdens and structural limitations. Students generally respond positively, describing the approach as more interactive, engaging, and socially relevant. This study concludes that integrating Islamic values with Freire’s critical pedagogy provides a strong foundation for vocational education grounded in social justice. Policy implications include strengthening teacher training, making curricula more flexible, and adopting evaluation methods that emphasize social contribution.
