Evaluation of the lighting system in drawing studio at the E12 building, Faculty of Engineering UNNES

Abstract

A room can be said to be a good one if the lighting following the requirements of needs depends on the function of the room. The room studied in this study was a drawing studio room in E12 Building, Faculty of Engineering UNNES. This room has a condition where the spread of light entering from the window is uneven so during the day the lights must always be turned on. The purpose of this study is to measure and evaluate the lighting intensity of the drawing studio space. This research was conducted using descriptive and evaluative methods. The data obtained is sourced from the results of direct light intensity measurements on the object of research conducted in the morning, afternoon, and evening for three days using a lux meter and measurements made referring to SNI 16-7062-2004 about measuring the intensity of lighting at work. The results of the measurement of lighting intensity in the image studio room will be compared with the SNI recommended standards. According to SNI 03-6575-2001, the standard requirement for a lux studio drawing space is 750 lux. The result, both when the lamp is turned on and the lamp turns off the measurement results do not meet the standards. It is recommended to increase the intensity of artificial lighting (lights) in the drawing studio until it meets the SNI 750 lux standard. From the results of calculations with the lumen method, it is recommended to replace each lamp with a lamp that has a light current of 9360 lumens.
