Abstract

The Griyo Mulyo Jabon Landfill (TPA) in Sidoarjo has the potential to emit hydrogen sulfide (H₂S) and ammonia (NH₃) gases due to the anaerobic decomposition of organic waste. The release of these gases may contribute to ambient air quality deterioration, unpleasant odors, and reduced environmental comfort for surrounding communities. Furthermore, meteorological conditions significantly influence the transport and dispersion behavior of landfill gas emissions in the atmosphere. This study aimed to determine H₂S and NH₃ concentrations in ambient air, assess their compliance with applicable air quality standards, and evaluate the dispersion patterns of these gases around the Griyo Mulyo Jabon Landfill using atmospheric dispersion modelling. A quantitative approach was applied using the Gaussian dispersion model AERMOD. Ambient air sampling was conducted at four monitoring locations, including two points within the landfill area and two points outside the landfill boundary. Hydrogen sulfide (H₂S) concentrations were measured according to SNI 8605:2018, while ammonia (NH₃) concentrations were analyzed based on SNI 19-7117.6-2005 using the impinger method. Meteorological parameters, including wind direction, wind speed, air temperature, and humidity, were incorporated as model inputs. Model performance was evaluated using the Mean Absolute Percentage Error (MAPE) and Index of Agreement (IOA). The results showed that H₂S concentrations in the old and new landfill zones were 0.03 ppm, while NH₃ concentrations were 2.10 ppm and 2.27 ppm, respectively. The highest concentrations occurred in the active waste disposal area. The dispersion simulation demonstrated that gas movement followed the dominant east-southeast wind direction, with concentrations decreasing as the distance from the emission source increased. The low MAPE values (0.4% for H₂S and 0.3% for NH₃) indicated excellent model accuracy in representing field conditions.

Abstract

Rumah sakit menghasilkan limbah padat, cair, dan gas yang berpotensi mengandung mikroorganisme penyebab penyakit, bersifat infeksius, serta mengandung bahan kimia berbahaya maupun zat radioaktif dalam kadar kecil yang berdampak negatif terhadap kesehatan manusia dan lingkungan. Pengolahan limbah berperan penting dalam mengurangi sifat berbahaya serta memastikan kualitasnya sesuai standar sebelum dibuang ke lingkungan. Penelitian ini bertujuan mengevaluasi sistem operasional serta pemeliharaan Instalasi Pengolahan Air Limbah (IPAL) Rumah Sakit X, berdasarkan Buku 3 Pedoman SOP UPTD Pengelola Air Limbah Domestik Tahun 2018 dan Peraturan Gubernur Jawa Timur No. 72 Tahun 2013. Metode yang digunakan adalah dengan cara melakukan observasi, wawancara dengan pengawas operator dan juga melakukan dokumentasi unit pengolahan di IPAL. Hasil evaluasi menunjukkan bahwa sistem pengolahan limbah telah berjalan sesuai prosedur, di mana efisiensi penyisihan parameter pencemar untuk kadar BOD, COD, TSS, dan mikroorganisme patogen memenuhi baku mutu. Pengelolaan IPAL secara rutin dan pencatatan parameter harian juga telah dilakukan dengan baik. Kesimpulannya, hasil evaluasi menunjukkan bahwa tingkat kesesuaian operasional IPAL terhadap Peraturan Gubernur Jawa Timur Nomor 72 Tahun 2013 mencapai 100%. Berdasarkan dengan Buku 3 SOP Aset Operasi UPTD, tingkat kesesuaian operasional tercatat sebesar 93,3% dengan 28 dari 30 parameter terpenuhi, sedangkan tingkat kesesuaian pemeliharaan sebesar 89,65% dengan 26 dari 29 parameter terpenuhi.

Abstract

Indoor air quality in office buildings plays a crucial role in human life as it directly impacts the health and productivity of building occupants. This study aims to assess indoor air quality and compare it with Ministry of Health Regulation No. 48 of 2016, examine the relationship between temperature and humidity on indoor air pollutants, and map the distribution of CO, CO2, PM10, and VOC concentrations in staff rooms. The analytical methods used include descriptive analysis, quantitative analysis using the Spearman correlation test, and spatial analysis using Surfer 16. The results of the study indicate that several parameters, such as temperature, humidity, light intensity, CO₂, and PM10, do not meet quality standards at most points. However, for CO and VOCs, concentrations were found to be significantly below quality standards. The Spearman correlation test showed a significant relationship between temperature and VOCs with a p-value of 0.021<0.05 and a correlation coefficient of -0.467, indicating a negative relationship with a moderate level of strength. The distribution mapping results are shown in red for areas with high concentrations or those not meet quality standards, while green indicates areas with concentrations below quality standards. This is an important step in evaluating and developing ventilation and lighting systems, as well as maintaining indoor air quality in accordance with established standards.
