Siwabessy Multipurpose Reactor Facility (RSG-GAS) at BRIN Serpong is used for research, isotope production, and nuclear technology development and occupational health and safety (OHS) is a very important aspect of the facility. Although there has never been a nuclear accident at the RSG-GAS nuclear facility, to anticipate this, the first study on the possibility of employees making errors at the RSG-GAS facility has been conducted. The aim of this research is to analyze the effectiveness of health, safety and culture of employees working at the Safety division of the reactor RSG-GAS. A mixed method approach with two main perspectives of the workforce and the Institution has been carried out. Data collection and empirical facts that demonstrate the urgency of implementing an OHS/K3 system have been implemented using mix-method. A study of workers' awareness, compliance, and perceptions of OHS implementation, including the application of SOPs in daily operations, was conducted. The results indicate that the effectiveness of OHS implementation at the RSG-GAS BRIN Serpong facility is currently mostly supported by the strength of the regulatory system. The OHS implementation going forward depends not only on adding regulations or improving safety technology, but also on strengthening safety culture consistent training, and a focused, sustainable management commitment. The good implementation of OHS at RGS-GAS BRIN Serpong then makes Indonesia a pioneer in implementing OHS, especially in ASEAN, because the RSG-GAS Reactor is currently the largest nuclear reactor in the Region.</p> Umi Rusilowati Hamsinah B.

The research aims to analyze the individual and combined effects of these variables in improving students’ ability to understand, manage, and utilize digital economic technologies effectively. A quantitative survey method was employed. The population consisted of Economics Education students in South Tangerang who had participated in project-based courses and were enrolled in at least the third semester. Using purposive sampling, a minimum of 200 students from Universitas Pamulang were selected as respondents. Data were collected through observations, interviews, and structured questionnaires. The research instruments were tested for validity and reliability before data collection. Furthermore, classical assumption tests, including normality, multicollinearity, and heteroscedasticity tests, were conducted prior to multiple linear regression analysis. The findings indicate that project-based immersive learning has a positive and significant effect on students’ digital economic literacy. Digital financial experience also positively and significantly contributes to improving digital economic literacy. Students with greater exposure to digital financial services tend to demonstrate higher levels of digital economic literacy. Moreover, the simultaneous influence of project-based immersive learning and digital financial experience significantly enhances students’ digital economic literacy. These findings suggest that integrating project-based learning with practical digital financial experiences can effectively strengthen students’ competencies in navigating the digital economy and adapting to ongoing digital transformation.</p> Ambar Widya Lestari Citra Eliyani Purwati Yuni Rahayu ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 2026-07-20 2026-07-20 10 1 13 24 10.33753/mandiri.v10i1.411
