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

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