Abstract

This study analyzes the lighting system of XYZ Building based on the lighting standard SNI 6197:2020. Based on the measurement results, the majority of rooms have light intensity below the established standard. The primary contributing factors include the use of inappropriate lamp types, an insufficient number of lighting points, dark-colored walls that absorb light, and a lack of proper lamp maintenance. The analysis indicates that although the lighting power per square meter is relatively efficient, visual comfort is not achieved. Recommended improvements include replacing old lamps with high-intensity LED lights, adjusting the lamp layout, and changing wall colors to enhance light reflectivity. The implementation of these recommendations is expected to improve lighting quality, ensuring compliance with the established standards. This study provides a crucial foundation for improving lighting systems in similar buildings to enhance energy efficiency and user comfort.

Abstract

This study aims to analyze power consumption and evaluate the potential energy savings of the lighting system in the DEF Building, which has various room functions including offices, laboratories, meeting rooms, and libraries. The study was conducted with a descriptive quantitative approach based on field measurement data. Data collection includes measuring lighting intensity (lux), inventory of types and number of lamps, and power consumption (watt). The measurement results were compared with the Indonesian National Standard SNI 6197:2020 to assess the minimum lighting level and maximum power limit. In addition, a simulation of replacing conventional lamps with LED lamps was carried out using Dialux Evo software. The results showed that most rooms had power consumption per square meter that was still efficient (<12 W/m²), but many rooms did not meet the minimum lighting standards. The simulation of replacing lamps with LEDs resulted in significant power savings, with a total reduction in energy consumption of 928.93 kWh per month or equivalent to electricity cost savings of around Rp1,362,997.48. Replacing lamps was also able to improve the quality of lighting in rooms that previously did not meet the standards. This study shows that effective lighting system management through LED lamp retrofitting can be an important strategy in supporting building energy efficiency.

Abstract

Solar Power Plant is a power plant by utilizing sunlight. In this study, the focus is on the use of off-grid solar power systems. The purpose of this study is to determine the effect of luminous intensity, humidity, and temperature on the output voltage of a solar power plant. The research method used is experimental. The maximum output voltage of the solar panel is 19.2 V obtained at 01.00 pm. During these conditions, the luminous intensity value is 121000 lux at an air humidity of 52.4% with a temperature of 40.50C. The results showed that (1) the greater the luminous intensity, the greater the output voltage of the solar panel. (2) If the greater the humidity, the smaller the output voltage of the solar panel. (3) If the greater the temperature, the greater the output voltage of the solar panel.

Abstract

Increasing energy efficiency is one of the most important functions for reducing energy costs as well as production costs. One way to reduce the use of electrical energy consumption is by saving energy. This study aims to determine how much energy savings at PT ABC through an energy audit. An energy audit is carried out with two main activities, namely identifying the profile of patterns of electricity use and analysis of power quality. The results of the analysis are then expected to be the basis for knowing the potential for energy savings and energy conservation in the industry. The method used in this study begins with field observations, measurements of electrical systems, and measurements of production machines and production support equipment. Based on some data, both primary data and secondary data, an analysis is carried out through calculations to determine potential energy-saving opportunities. The main energy source used at PT. ABC is from PLN with 1 subscription to a 3-phase system with an installed power of 197 kVA. Energy use or consumption for a year is 804,279.97 kWh. Opportunities for energy savings through energy audits that have been carried out are expected to have an impact on the company, namely energy cost savings of IDR 137,344,162 per year
