Abstract

Physical comfort in the learning environment relies on the use of good electrical equipment, which significantly supports the learning process. To enhance comfort, it is essential to maximize the use of electrical appliances, although this can lead to increased energy consumption. Most of the primary energy for power generation comes from non-renewable sources, which contribute to pollution. In Indonesia, not all regions have access to electricity that meets desired comfort standards. One such area is SDN Rancagong 1 and 4, where the use of power tools to support the learning process is still minimal. Measurements of comfort standards revealed that the air temperature exceeded the SNI 03-6572-2001 standard by 4°C, while humidity levels surpassed the same standard by 9%. Additionally, illumination levels were less than a third of the SNI 6072-2020 lighting standard. Qualitative feedback from room occupants supports these findings. To address these issues, the proposal includes the use of renewable energy sources such as solar energy. To avoid losses and ensure effective implementation, simulations were conducted using PVSyst software. The results indicated a power generation potential of 7,829.33 kWh per year, with a performance ratio of 49%, a solar fraction of 100%, an SOW cycle of 98.4%, and a static SOW of 90%. With this power output, it is anticipated that electricity can be provided for equipment that enhances comfort standards, such as air conditioning and additional lighting.

Abstract

Humans spend most of their time doing activities inside a room. Room comfort becomes one of the important factors to support human activities. The lack of comfort can trigger sick-building syndrome for room occupants which leads to nausea, irritation, loss of concentration and other types of sickness. Thus, a study is conducted in the Physics Engineering laboratorium to measure the physical comfort based on temperature, relative humidity, and illuminance using CEM DT-8820 environment meter. A quantitative descriptive method is used. In addition, a survey is made to collect sick-building syndrome occurrence data by laboratorium occupants. It is obtained that temperature is lower than 24?-27?, relative humidity in accordance (by 55% - 56%) and illuminance under 500 lux as the standard for laboratory. Based on questionnaire results, sick-building syndrome that appears on respondents are dry throat by 23,3%, dry lips by 40,0%, drowsiness by 66,7%, poor concentration by 33,3%, etc. which correlates to temperature by -0,0156 (very low negative correlation), relative humidity by -0,1297 (low negative correlation) and illuminance by -0,4393 (moderate negative correlation).
