The DC-DC boost converter is a crucial component in power management systems, functioning to step up the DC voltage from a lower to a higher level. However, the effectiveness of the converter is often hindered by power losses and suboptimal efficiency. This study presents a performance analysis of three control methods applied to the Boost Converter: Conventional PWM, PWM with Modified Duty Cycle Switching (MDCS), and a Proportional-Integral (PI) Controller. Simulation results indicate that the Conventional PWM method exhibits low efficiency (88%) along with significant overshoot and steady-state error. The MDCS method demonstrates improved efficiency (91.7%) and a faster response time; however, it tends to experience substantial voltage fluctuations, indicating instability during transient conditions. In contrast, the PI controller delivers the most optimal performance, achieving the highest efficiency (94%) and a stable output voltage without significant fluctuations. The PI technique effectively maintains the reference voltage with minimal steady-state error and overshoot, making it an ideal solution for applications requiring high stability and efficiency. In conclusion, the PI controller is recommended for power conversion applications that demand stability, while the MDCS method is more suitable for systems requiring fast response with consideration for stability. The Conventional PWM method should be avoided in applications that require high efficiency

Occupational Safety and Health (OSH) is a fundamental aspect to ensure the security and continuity of academic activities, especially in technical laboratory environments that are highly prone to fire hazards. The Electrical Engineering Laboratory of the Faculty of Engineering, University of Mataram, is identified as a high-risk area due to the use of high-voltage electricity, electronic devices, and flammable materials. According to the fire triangle theory comprising fuel, heat, and oxygen fires can be prevented by eliminating one of these elements. A primary preventive effort in this context involves the use of fire extinguishers (APAR) and adequate training on their proper use. This study aims to evaluate the effectiveness of APAR training and awareness campaigns among active laboratory students. The training method applied an andragogical approach with the PASS technique (Pull, Aim, Squeeze, Sweep), accompanied by pre- and post-tests, simulated fire suppression, and participatory observation. Results showed a significant improvement in students’ understanding, with the average score increasing from 18.75% to 88.38% and the standard deviation decreasing from 9.22 to 6.16, indicating more uniform comprehension among participants. A paired t-test revealed a highly significant difference (p < 0.0001), and one-way ANOVA supported that the training had a measurable effect on all evaluated aspects. Beyond cognitive gains, students also demonstrated positive affective and psychomotor responses through active participation and practical suggestions, such as improving extinguisher placement and adding usage instructions. These findings indicate that the APAR training program not only enhances technical knowledge but also cultivates a culture of safety within the academic environment. It is recommended that such training be institutionalized as part of the laboratory's integrated OSH management system
