Abstract

Air pollution is an environmental issue that has a broad impact on human health and ecosystem balance. PT PLN Nusantara Power UP Nagan Raya as a coal-fired steam power plant (PLTU) has the potential to produce exhaust emissions that can reduce air quality in the surrounding area. This study aims to assess the impact of exhaust emissions on ambient air quality in organizations around the PLTU. The study uses a quantitative descriptive approach by measuring several air pollutant parameters, namely SO₂, NO₂, CO, O₃, NMHC, PM₁₀, PM₂.₅, and Pb at the UA-1 observation point located east of the PLN Nusantara Power, then compared with ambient air quality standards based on PP No. 22 of 2021. The measurement results show that all pollutant parameters are still below the national air quality standard threshold, including SO₂ <33.438 μg/m³, NO₂ <6.143 μg/m³, CO 2298.91 μg/m³, PM₁₀ 22.80 μg/m³, and PM₂.₅ 16.11 μg/m³. This indicates that at the time of the measurement, coal burning activities at the PLN Nusantara Power had not had a significant impact on air quality in surrounding organizations. However, continuous monitoring is still needed to ensure air quality remains safe and prevent potential long-term health risks.

Abstract

In the era of globalization, industrial development requires companies to maintain efficient and sustainable production systems. One of the critical components in palm oil processing is the thresher machine, which functions to separate fruits from fresh fruit bunches (FFB). This study aims to analyze the maintenance mechanism of the thresher machine at PT. Beurata Subur Persada using a qualitative descriptive approach. Data were collected through interviews, direct observations, and literature studies. The results show that the thresher machine plays a vital role in ensuring the continuity of the production process, and its performance is highly dependent on proper maintenance practices. The company implements a preventive maintenance system consisting of routine, weekly, monthly, and annual activities, including inspection, cleaning, repair, and component replacement. These maintenance practices have proven effective in improving machine reliability, extending component service life, and minimizing unexpected failures. However, several challenges remain, such as component wear, potential leakage, and insufficient maintenance documentation. Therefore, improvements in maintenance management, including systematic recording, enhanced monitoring, and workforce training, are necessary to optimize machine performance. Overall, effective preventive maintenance contributes significantly to operational efficiency and sustainability in palm oil production.
