Abstract

This study aims to model the dispersion of air emissions (NOₓ and SO₂) from the flarestack at the Onshore Receiving Facilities (ORF) of PT X using AERMOD software. Wind patterns affecting the emission distribution were analysed using WRPLOT View software. The modelling results were verified with ambient air quality measurements to ensure accuracy and reliability. The windrose analysis showed that wind directions shifted between semesters: west-to-east in semester I and east-to-west in semester II of 2023, affecting the dispersion patterns. Isopleth maps showed that NOₓ and SO₂ concentrations remained stable, with maximum concentrations of 0.28 µg/m³ and 0.028 µg/m³, respectively. Concentrations of both pollutants complied with Indonesia's air quality standards (Government Regulation No. 22/2021). However, actual ambient measurements showed higher concentrations due to external sources not included in the model. These results highlight the important role of meteorological factors in emission dispersion and the need for comprehensive pollution control strategies.

Abstract

This research aims to analyze ambient air quality in the city of Surabaya, with a focus on four main locations: industry, transportation, offices and residential areas during two different periods, the dry season and the rainy season in 2023. This analysis is important for assessing the influence of urbanization and industrial activity. to the environment and public health. The method used is descriptive and comparative observational, where measurements are made of main pollutant parameters such as SO2, CO, NO2, O3, Pb, NMHC, PM10, PM2.5, and TSP. Sampling was carried out twice at each location, in accordance with SNI 19-7119.6-2005 and PPRI No. 22 of 2021 standards. The research results showed that the concentrations of all pollutants were below the specified threshold, indicating the effectiveness of existing air control policies. However, there are differences in pollutant concentrations between locations and significant seasonal changes, requiring more dynamic and tailored pollution management strategies. The study's conclusions suggest the importance of continuous monitoring, increased green space, public education about pollution, as well as stricter policies to control pollutant emissions. This research provides valuable empirical data for policy makers to develop effective strategies for managing air quality and reducing health risks in Surabaya..

Abstract

Canteen wastewater is a type of domestic effluent generated from cooking and dishwashing activities, typically containing high levels of organic matter such as fats, oils, food residues, and key pollutants like Total Suspended Solids (TSS) also Chemical Oxygen Demand (COD). This study evaluates the effectiveness of sweet orange peel (Citrus sinensis)-based bio-coagulant in removing TSS also COD from canteen wastewater. Orange peel was selected due to its bioactive compounds like a pectin, flavonoids, also organic acids, that contain hydroxyl and carboxyl functional groups vital for coagulation-flocculation processes. Treatment was conducted using the jar test method with variations in pH, dosage, and settling time. The results showed that the optimum condition was achieved at pH 3, a dosage of 2 g/L, also a settling time of 45 minutes, resulting in TSS removal efficiency of 30.48% and COD removal of 29.29%. These findings confirm the potential of orange peel as an eco-friendly natural coagulant for canteen wastewater treatment.

Abstract

This study aims to analyze the Total Dissolved Solid (TDS) levels at Water Treatment Plant 2 (IPA 2) of PT Hanarida Tirta Birawa which uses the Pelayaran River as a source of raw water. The results of the analysis show that the TDS value of raw water tends to be high at 01.00 and 07.00 compared to 13.00. After the processing process, most of the values ​​still meet the quality standards, but there is an increase in TDS. The increase in TDS values ​​after processing can occur due to the use of coagulant doses that may be too high. It is recommended to optimize the water treatment process by reducing the coagulant concentration to increase the efficiency of TDS removal. It is expected that the quality of the processed water can be improved and meet drinking water quality standards better.

Abstract

Environmental pollution conditions caused by the increasing accumulation of waste have occurred a lot in Indonesia, including in the hero city of Surabaya. Based on data analysis from the Surabaya City Environmental Service, the total waste generation in Surabaya City reaches 1600 tons per day which goes into the Benowo Final Disposal Site (TPA). One of Surabaya City's efforts to reduce and manage waste is by implementing the Zero Waste Village concept. This study focuses on data on facilities and infrastructure in RW 13, Mojo Village, Surabaya to reduce the waste generated. This area was chosen because it has the potential to implement the zerowaste village program to minimize and optimize waste. The amount of waste generation in the RW 13 area of Mojo Village is 140.6 kg/day with an average waste generation per person of 0.052 kg/day. This figure is still below the SNI 8632:2018 standard concerning Procedures for Planning Operational Engineering for Urban Waste Management, namely 0.65 – 0.70 kg/person/day for household waste sources.
