Abstract

Inverter material is one of the essential materials in power electronics courses. An inverter is an electronic device that converts direct current (DC) into alternating current (AC). This concept is the foundation of electronics. Because the power electronics course is a practicum course, a practicum module is required as an intermediary teaching medium; this practical module discusses 3-phase inverter material, which uses the pulse width modulation (PWM) and sinusoidal pulse width modulation inverter (SPWM) switching methods. Through Tinkercad software, the circuit is assembled, and the output wave results from the two methods used are seen in designing the 3-phase inverter practical module using the Research and Development method. This research uses media and material validation sheet instruments to determine the feasibility of the 3-phase inverter practicum module. The research results showed that the percentage of media experts was 94%, material experts were 81%, and language experts were 84%. Hence, the 3-phase inverter practicum module is very suitable for use and can make it easier for students to understand inverters. Thus, developing a 3-phase inverter practicum module can effectively increase students' understanding of inverter material and interest in learning. It can also be an alternative for lecturers in teaching.

Abstract

This study aims to see whether the electrical lighting installation at the Regional Drinking Water Company (Indonesian, abbreviated as PDAM) of Tomohon City follows the General Requirements for Electrical Installations (abbreviated as PUIL) or vice versa. Using the analysis approach, direct observation was performed at the research site, and after performing the study, it was discovered that many electrical lighting installation requirements did not satisfy PUIL. Following the measurements and calculations, it was found that none of the lighting in building A met PUIL standards, while for building B, there was only 1 room whose lighting met PUIL standards. Furthermore, there were several rooms where the lights were not installed. Of course, this can affect the daily activities in the room. From the results of the study, it is inevitable that the electrical lighting installation in the PDAM building in Tomohon City must be repaired immediately and should follow the applicable PUIL.

The development of Tomohon City as a tourism hub in North Sulawesi has accelerated significantly, triggering a surge in economic activities and consequently increasing the demand for electrical energy. This study aims to analyze the relationship between economic growth and electricity consumption in Tomohon City, identifying the implications for energy infrastructure planning. A descriptive survey method was employed, using secondary data sourced from the Central Statistics Agency and PT PLN. Data on electricity supply and economic indicators such as Gross Regional Domestic Product (GRDP) were presented in tables, graphs, and diagrams to illustrate growth patterns from 2010 to 2021. Findings reveal that both electricity consumption and installed capacity have increased steadily, with electricity sales rising from 38.4 GWh in 2014 to 48.3 GWh in 2020 and customer numbers increasing from 24,575 to 29,770 over five years. Economic indicators such as GRDP also showed consistent growth, particularly in the tourism, trade, and accommodation sectors. The average annual growth in electricity production was 4.68%, highlighting the need for proactive energy planning. The study concludes that the economic development of Tomohon City is positively correlated with rising electricity demands. It recommends that stakeholders, including PT PLN and local government bodies, develop anticipatory infrastructure strategies to ensure sustainable energy supply, particularly as tourism continues to expand. This research provides critical insight into aligning energy provision with regional economic development priorities.
