The chair painting process in the furniture industry often requires operators to work in unnatural postures, such as bending over and reaching excessively. This condition is caused by workstations that are not designed according to the dimensions of the operator's body, thus having a high potential to cause musculoskeletal disorders (MSDs) and reduce productivity. This study aims to design an ergonomic jig and fixture to assist in the chair painting process, thereby creating a safer, more comfortable, and more efficient work system. The design method was carried out using a participatory ergonomic approach through the collection of anthropometric data from 30 operator samples. Seven key dimensions of the body relevant to work activities were measured, including Standing Elbow Height (SEH), Standing Shoulder Height (SSH), Forward Reach (FR), Standing Hip Height (SHH), Standing Knee Height (SKH), Standing Thigh Height (STH), and Standing Lower Back Height (SLBH). Seven key body dimensions relevant to work activitiesâ€”including Standing Elbow Height (SEH), Standing Shoulder Height (SSH), Forward Reach (FR), Hand Width (HW), Grip Diameter (GD), Standing Eye Height (SEH), and Shoulder Width (SW)â€”were measured and statistically processed to obtain the 5th percentile (P5), 50th percentile (P50), and 95th percentile (P95) values. These percentile values were then used as quantitative references in determining the technical specifications of each component of the designed assistive device. The result of this research is a conceptual design for a grip and clamp with superior ergonomic features. The main specifications of this design include: (1) A height adjustment mechanism that can be adjusted within a range of 95.5 cm (P5 TSB) to 109.7 cm (P95 TSB) to accommodate various operator postures; (2) A 360Â° rotation mechanism that allows the operator to reach the entire surface of the chair without having to change position; and (3) A locking lever design with a diameter of 4.6 cm (P50 DG) placed within a maximum reach radius of 61.3 cm (P5 JTD) from the operator. With the implementation of this assistive device design, the operator's working posture can be significantly improved, thereby minimizing the risk of injury due to repetitive work. This design has the potential to not only improve occupational health and safety, but also the efficiency of the painting process by reducing unnecessary movements

Air pollution on roads and indoors has a bad impact on human health, Since air pollution may lead to a number of illnesses, a device that is useful to track this quality of this air utilizing Arduino, MQ2 sensor, DHT11 sensor and MQ135 sensor as well as the Blynk program, a tool designed to facilitate our ability to see from our cell phones. This test used 3 experiments using lighter gas, perfume and burnt smoke with each value on the resulting gas sensor being different. For pre- trials on lighter gas and perfume when conducting experiments, these two experiments can activate the buzzer with an average value on the mq135 and mq2 sensors of 60-200 ppm. For smoke that is burned, the buzzer is not activated because the gas level received is below 10 ppm.

ANALISIS RISIKO KESELAMATAN DAN KESEHATAN KERJA (K3) DI LINGKUNGAN SEKOLAH DASAR DENGAN MENGGUNAKAN METODE HAZARD IDENTIFICATION RISK ASSESSMENT AND DETERMINING CONTROL (HIRADC)

Occupational Health and Safety (OHS) is a crucial aspect in creating a safe and productive environment. Occupational Health and Safety (OHS) issues have traditionally focused on the industrial sector, yet schools, as venues for educational processes, also pose potential hazards that can threaten the health and safety of students. This study aims to analyze potential hazards in elementary schools using the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) method. The study was conducted at MI Tazkirunnas, East Jakarta, using a quantitative descriptive approach. Data were collected through observation, interviews, and documentation of school activities and facilities. The analysis showed that 56% of areas/activities were categorized as medium risk, 25% as high risk, and 19% as low risk. The most common hazards included poorly maintained electrical installations, slippery floors, unsafe sports facilities, and the lack of emergency evacuation routes. Recommendations for control include improving physical facilities, implementing OHS SOPs, providing safety signs, and training teachers and students. These findings demonstrate the importance of implementing OHS early in schools to build a safety culture and prevent accidents.

PENTINGNYA WATER SPRINKLER UNTUK MENINGKATKAN EFEKTIVITAS PENCEGAHAN KEBAKARAN DI BANGUNAN ASRAMA TOWER POLITEKNIK PENERBANGAN INDONESIA CURUG

Fire is one of the disasters that can cause significant losses, both in terms of material damage and threats to human safety, especially in multi-story buildings such as dormitories. The Tower Dormitory of the Indonesian Aviation Polytechnic Curug currently lacks an active fire protection system in the form of a water sprinkler, which should be mandatorily installed in accordance with the provisions of the Minister of Public Works Regulation Number 26 of 2008. This study aims to analyze the importance of installing a water sprinkler system to improve the effectiveness of fire prevention in the building. The research method used is descriptive qualitative, with data collection techniques including observation, interviews, and documentation. The results show that the presence of a water sprinkler is highly important to automatically respond to fires at an early stage, thereby controlling the spread of flames, minimizing casualties, reducing building damage, and providing additional time for occupants to evacuate. Moreover, water sprinklers also serve to meet the safety standards of multi-story buildings. Therefore, the installation of this system is recommended as a priority in efforts to improve fire protection systems within the Tower Dormitory of the Indonesian Aviation Polytechnic Curug.

Pemanfaatan Thermoelectric Generator (TEG) untuk Penyimpanan Energi Panas dari Limbah Industri

2025-12-19T11:19:08+08:00

The increase in industrial activity in Indonesia has resulted in a large volume of waste heat that is often discarded without being utilized. One promising solution to convert this waste heat into electrical energy is the use of a Thermoelectric Generator (TEG). This study examines the utilization of the TEG type SP1848-27145 to harness industrial waste heat within a temperature range of 150–250 °C, as well as to evaluate the potential of the generated energy for storage applications. The utilization of industrial waste heat energy is an efficient strategy to support clean energy transition and industrial sustainability. This study aims to analyze the potential of TEG type SP1848-27145 in storing heat energy from industrial waste within a temperature range of 150–250 °C.
