Abstract

The aim of this study was evaluated heats source at work using Wet Bulb Globe Temperature (WBGT) in ABC oil and gas company located in Semarang, Indonesia. This study relies on thermal comfort responses from 153 questionnaires collected from November to December 2020 and objective measurements using WBGT parameter such as natural wet-bulb temperature, globe thermometer temperature, dry-bulb temperature and humidity. Then the clothing insulation and metabolic rate are also included in the determination of the WBGT value. There are 4 areas that not meet for Threshold Limit Value by American Conference of Governmental Industrial Hygienists (ACGIH) due to the WBGT results on moderate work shows more than 28 ºC. It was found that several areas are not meet the humidity requirements due to the humidity value is above 60%.  In addition, heat source mapping is carried out to determine heat source radiation in the workplace. It is concluded that the heat source is at several points are detected. According to the responses on the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) seven-point sensation scale “neutral” had most of the votes. The purpose of the study is also to provide recommendations for workers to avoid heats stress at work.
