Abstract

Peningkatan kualitas kesehatan melalui perbaikan kondisi lingkungan merupakan tanggung jawab banyak pihak. Pengetahuan masyarakat menjadi salah satu faktor penting dalam proses pengolahan sampah. Pengabdian ini menggunakan pendekatan partisipatif dengan melibatkan masyarakat setempat. Metode yang digunakan meliputi sosialisasi dan penyuluhan secara langsung kepada masyarakat dari dua pedukuhan, yaitu Pedukuhan Bintaran Kulon dan Payak Cilik di Kelurahan Srimulyo, Kecamatan Piyungan, Kabupaten Bantul dengan jumlah sampel sebanyak 33 orang, serta pembuatan alat pirolisis sederhana dari drum bekas sebagai prototype. Instrumen yang digunakan adalah kuesioner untuk mengukur tingkat pengetahuan peserta tentang pengelolaan sampah sebelum dilakukan sosialisasi. Analisis data dilakukan secara deskriptif terhadap hasil kuesioner, dengan pengelompokan data dalam kategori tingkat pengetahuan rendah, sedang, dan tinggi berdasarkan persentase jawaban benar. Masyarakat telah memiliki tingkat pengetahuan mengenai jenis-jenis sampah dan konsep pemilahan sampah masyarakat berada dalam tingkat yang cukup baik. Namun, sarana dan prasarana pemilahan dan pengolahan sampah masih perlu ditingkatkan. Pengenalan alat baru untuk pengolahan sampah dengan menggunakan pirolisis diharapkan menjadi upaya inovasi pengolahan sampah untuk mengurangi tumpukan sampah di Tempat Pengelolaan Sampah Terpadu Piyungan yang telah mencapai kapasitas maksimal dan telah ditutup, serta mengurangi volume sampah yang dibuang ke TPST Piyungan.

Abstract

Rapid population growth in the Babelan and Sukatani areas of Bekasi Regency has significantly increased the demand for clean water, posing a challenge for PDAM Tirta Bhagasasi in maintaining a reliable and sustainable drinking water supply. This study aims to evaluate the performance of the existing water distribution network and propose an optimized development plan to meet projected demand through 2041. The methodology includes population and water demand projections, evaluation of Water Treatment Plant (WTP) capacity, hydraulic simulation using EPANET 2.0, and cost estimation for network development. The results show that by 2041, the population in Babelan and Sukatani is projected to reach 418,390 and 149,700 people respectively, with corresponding water demands of 481.8 L/s and 172.5 L/s. The existing WTP capacities are insufficient, particularly in Sukatani, which currently operates at only 44 L/s. Hydraulic simulation indicates that a looping distribution system is more effective than a branching system in improving water pressure and reducing losses. However, implementing a looping system requires a higher investment, estimated at approximately IDR 15 billion, compared to IDR 10 billion for a branching system. Given these findings, the study recommends that PDAM Tirta Bhagasasi prioritize increasing WTP capacity and adopt a looping-based distribution network to ensure long-term service reliability, particularly in high-growth areas. This approach offers both technical and economic benefits for future water supply planning and can serve as a model for other regions facing similar challenges.

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.
