Abstract

Coal-fired power plants will emit several types of pollutants into the ambient air such as particulates and gases. One way to estimate the extent of the impact distribution of these pollutants is by using air quality modeling. The model used in this study is Calpuff, where this model is a non-steady state model and is influenced by variations in meteorological factors. The research location is PLTU Pangkalan Susu (2x200 MW) with SO2 and NO2 parameters. The purpose of this study was to calculate the concentrations of SO2 and NO2 with Calpuff, to validate modeling with field observations and to simulate the distribution of impacts. The results showed that the concentration of SO2 model obtained was 0.32 - 3.57 µg/m3 and NO2 was 0.51 - 5.15 µg/m3. Meanwhile, the observation results showed that the SO2 concentration was 27 - 39.88 µg/m3 and NO2 was 19.77 - 29.73 µg/m3. The simulation results of the distribution of SO2 and NO2 concentrations with the Calpuff model show that the impact distribution area is in the direction of the wind in the windrose and the affected area is in the southwest of the PLTU Pangkalan Susu. The results of model validation for the values ​​of d = 0.97, r = 0.616 - 0.665 and FB = -1.719 - -1.849, which means that the Calpuff model is quite valid and can be applied to predict the impact distribution area at PLTU Pangkalan Susu.

Abstract

Fasilitas sanitasi yang layak berperan penting dalam menciptakan lingkungan belajar yang sehat dan nyaman. Namun, SD Negeri 060955 di Medan menghadapi berbagai kendala sanitasi, seperti toilet yang rusak, minimnya tempat sampah, dan fasilitas cuci tangan yang tidak berfungsi dengan baik. Keterbatasan anggaran menjadi tantangan utama dalam upaya perbaikannya. Melalui program pengabdian masyarakat ini, dilakukan perbaikan toilet, penyediaan tempat sampah terpilah, serta perbaikan fasilitas cuci tangan guna meningkatkan kualitas sanitasi sekolah. Sebagai bagian dari edukasi lingkungan, siswa diberikan pembelajaran mengenai Perilaku Hidup Bersih dan Sehat (PHBS) untuk menumbuhkan kesadaran akan pentingnya menjaga kebersihan dan kesehatan lingkungan sekolah. Kegiatan ini dilaksanakan melalui survei awal untuk mengidentifikasi permasalahan, renovasi fasilitas, serta sosialisasi bagi siswa dan tenaga kependidikan. Hasil evaluasi menunjukkan bahwa seluruh toilet kini berfungsi baik, fasilitas cuci tangan kembali operasional, dan tempat sampah telah tersedia sesuai standar pemilahan. Selain itu, siswa menunjukkan antusiasme serta partisipasi aktif selama edukasi lingkungan berlangsung, yang mengindikasikan adanya peningkatan kesadaran terhadap kebersihan lingkungan sekolah.
