Effect of Applying Strong Column Weak Beam to the Laboratory’s Artificial Lighting System

Abstract

Abstract Lighting is one of the crucial experiment factors in the laboratory. Laboratory’s lighting system that follows the Indonesian National Standard (SNI) can improve visual comfort during experiments. This research aims to determine the effect of strong column weak beam (SCWB) on illuminance in the laboratory according to SNI 6197:2011. The results were expected to provide recommendations for the implementation of SCWB in the laboratory so that the laboratory lighting system was more optimal. Digital Electronics Laboratory, E8 Building, Universitas Negeri Semarang had dimensions of 12m x 7m x 4m. The measurement of illuminance used general measurement and task measurements according to SNI 7062-2019. Illuminance data retrieval was carried out in two ways, namely observation and simulation. Measurement of laboratory’s illuminance by observation has been carried out for 10 days with repetition 10 times. The simulation of illuminance measurement used Dialux 10. Based on the results of observations and simulations, it can be seen that the Digital Electronics Laboratory did not follow SNI 6197:2011 with an illuminance of 31.3 – 137 lux. The simulation used the modifying lamp layout and applying TL LED (Philips Master LEDTube HO) so that the illuminance distribution of the Digital Electronics Laboratory followed SNI 6197: 2011 of 500 – 769 lux. The simulation results of the SCWB dimension variation showed that the recommended thickness of the SCWB was between 10 cm – 30 cm to obtain a more optimal illuminance.
