Abstract

This study investigates the impact of solar charge controller (SCC) type on battery charging in solar-powered electric scooters (e-scooters). The research compared maximum power point tracking (MPPT) and pulse width modulation (PWM) controllers by monitoring average output power, current, and voltage every 10 minutes. Results showed that under stationary conditions, MPPT controllers delivered higher efficiency, generating 5.87 W of power compared to PWM's 5.05 W. This advantage persisted even during scooter operation, with MPPT controllers producing 4.91 W versus PWM's 4.31 W. Overall, the findings demonstrate that MPPT SCCs offer a more efficient solution for charging e-scooter batteries.

Abstract

The installation and training of CCTV security systems at Pondok Pesantren Putra Baitul Qur'an Al-Khusyu Malang aimed to improve both security and the technical skills of students. The training covered the basics of CCTV technology, including installation methods, system components, and maintenance procedures, enhancing students' knowledge and preparing them for the job market. The hands-on approach proved effective, as participants were actively involved in the installation and configuration of CCTV systems. Before the training, only a small percentage of students were familiar with CCTV technology, but post-training assessments showed a significant increase in knowledge. This program not only contributed to a safer environment within the pesantren but also provided valuable technical skills that students could use in their careers or entrepreneurship. Despite challenges such as limited resources and infrastructure, the training successfully empowered the students with skills relevant to modern security needs. This initiative sets a model for other educational institutions to integrate technical training with religious education, fostering a more skilled and competitive generation

Abstract

This study investigates the impact of adding Zinc Oxide (ZnO) nanoparticles to radiator coolant to enhance the heat transfer performance of automotive cooling systems. The research explores the optimal concentration of ZnO nanofluids and examines operational conditions such as flow rates (7-11 lpm) and fluid temperatures (60°C, 70°C, and 80°C) to determine their effect on heat transfer performance. The results demonstrate that ZnO nanoparticles significantly improve the heat transfer coefficient, with the highest performance observed at a concentration of 0.35% ZnO and a temperature of 70°C. The optimal combination of flow rate (10 lpm) and temperature (70°C) resulted in a 62.86% increase in heat transfer compared to conventional coolant. This study provides valuable insights into selecting the optimal nanofluid concentration and operational conditions for improving vehicle radiator performance.
