Abstract

PT X merupakan perusahaan yang bergerak di sektor perkebunan dan pengolahan kelapa sawit. Dalam proses produksi minyak sawit mentah (CPO) dan minyak inti kelapa sawit (CPKO), perusahaan ini menghasilkan emisi NO₂, PM₁₀, dan SO₂ dari kegiatan pembakaran yang terjadi di dalam boiler dan genset. Emisi ini berpotensi memengaruhi kualitas udara ambien di sekitar area perusahaan dan dapat menimbulkan risiko kesehatan bagi masyarakat setempat. Penelitian ini bertujuan untuk menganalisis konsentrasi dan pola dispersi polutan NO₂, PM₁₀, dan SO₂, mengevaluasi tingkat risiko kesehatan, dan merumuskan strategi pengelolaan kualitas udara. Pendekatan yang digunakan melalui analisis hasil model dispersi AERMOD dan risiko kesehatan. Hasil simulasi menunjukkan bahwa rata-rata konsentrasi NO₂, PM₁₀, dan SO₂ di sekitar area perusahaan masih berada di bawah batas ambang yang ditetapkan dalam PP No. 22 Tahun 2021. Namun, hasil ARK dengan notasi Risk Quotient (RQ) mengindikasikan adanya risiko kesehatan non-karsinogenik yang signifikan bagi populasi yang terpajan. Oleh karena itu, beberapa strategi pengelolaan kualitas udara yang dapat dilakukan antara lain melakukan pemantauan berkelanjutan terhadap emisi melalui sistem Continuous Emission Monitoring System (CEMS), penggunaan teknologi pengendalian emisi pada boiler dan genset, penggunaan bahan bakar ramah lingkungan, dan mengimplementasikan program tanggung jawab sosial perusahaan (CSR) yang berfokus pada edukasi dan pengelolaan lingkungan.

Abstract

Yogyakarta City, as a cultural and tourism hub, experiences a high level of transportation activity, particularly in its historical and strategic areas. This results in an increase in emissions, such as sulfur dioxide (SO₂) and nitrogen dioxide (NO₂), which have a negative impact on public health and the environment. This study aims to analyze the spatial dispersion of SO₂ and NO₂ pollutants from transportation sector activities using the AERMOD model. The results of the emission inventory on 10 research roads indicate that the highest SO₂ emission load is found on Jalan KH Ahmad Dahlan, at 8,315.31 g/hour. In contrast, the highest NO₂ emission load is observed on Jalan Brigjen Katamso, at 704.50 g/hour. The type of diesel-fueled motorized vehicles, although relatively fewer in number, has a much greater contribution to SO₂ and NO₂ emissions than gasoline-fueled vehicles, especially motorcycles. The modeling results using AERMOD showed that the maximum concentrations of SO₂ and NO₂ reached 53.1 μg/m³ and 118 μg/m³, respectively, with the distribution pattern influenced by the dominant wind direction from the northwest and relatively low wind speed (0.5–2.1 m/s). The spatial pattern of the simulation results showed a decrease in concentration as the distance from the emission source to the sensitive receptors increased, such as the Malioboro and   Alun-Alun Kidul tourist areas. Validation of the model against actual monitoring data (Impinger instrument measurement results) yielded an average RMSPE value of 24% for the SO₂ parameter, which remained within the model validation tolerance limit. However, the RMSPE value for the NO₂ parameter reached 59%, indicating that the model's concentration estimate tended to overestimate the actual value.

Abstract

Access to clean water remains a critical issue in urban-fringe areas where population growth, inadequate sanitation infrastructure, and behavioral patterns intersect. This study investigates the role of psychosocial factors based on the Risks, Attitudes, Norms, Abilities, and Self-regulation (RANAS) model in influencing household water management behavior in Kelurahan Tahunan, Umbulharjo District, Yogyakarta. Using a cross-sectional design and multistage random sampling across representative neighborhoods, data were collected from 97 households and analyzed through multiple linear regression. Results show that perceived risk (β = 0.229, p = 0.035), social norms (β = 0.229, p = 0.028), and abilities (β = 0.321, p = 0.003) significantly affect household behavior in managing clean water, while attitudes and self-regulation were not statistically significant. The findings underscore the importance of integrating behavioral interventions with structural improvements, particularly in areas with limited sanitation infrastructure. This study advocates for targeted community education, infrastructure development, and policy interventions that prioritize social norms and capacity-building to foster sustainable water practices.
