Abstract

Employeeshabits that working in offices are spend more than two-thirds of their working hours sitting in front of their desks and give little attention to good body position at work. This condition can cause health problems for themselves such as increasing the risk of hemorrhoids, heart disease, diabetes, obesity, and damage to joints, muscle, and posture. Sometimes the worker does not realize and never count how long they have been sitting. So, one of the efforts to avoid the risk of health problems caused by sitting too long is to make an instrument to warn the effect of long-term sitting with the temperature parameters. LED consists of three colors, which is green which means safe, yellow indicating a near to dangerous state, and red color meaning dangerous and workers are advised to stand for a while until the LED shows the green color. The results of testing show people who have a weight of approximately 70 KG takes 172 minutes to pass the temperature of 37oC, and people who have a weight of approximately 110 KG takes 155 minutes to pass temperature 37oC. Woman's body temperature faster increased by 0.31oC compared to males based on sitting time. Bargraph as an indicator showing green color when body temperature less than 36oC, yellow bar graph active when body temperature is between 36oC to 37oC, and red bar graph is active when temperature the body is more than 37oC. The buzzer active if the body temperature has dangerous level when the temperature is above 37oC.
