Abstract

Central Java has several estuaries which highly populated in their area, generating high load of waste water discharge. Research conducted on two of the estuaries, Comal estuary in Pemalang and Garang estuary in Semarang. Waste water discharge from population around upstream river of Comal and Garang pollute both estuaries, which are in north coast of Central Java. The aim of this research is to determine the amount of pollutants which enter the estuary and become sediment in Comal and Garang river estuary. The amount of pollution has been analyzed by QUAL2Kw program which then the result would be input data for sediment analysis using MIKE 21 ECOLab program. The result of research state that Comal estuary has BOD concentration of 4.26 mg/L on west season and 4.21 mg/L on east season. While Garang estuary has BOD concentration of 18.21 mg/L on west season and 4.73 mg/L on east season.

Abstract

The risk of air pollution originating from the transportation sector constitutes a primary concern in this study. Terminal Jombor Yogyakarta, a Type B public transportation terminal with high vehicular activity serving Intercity–Interprovincial (AKAP), Intercity–Intraprovinical (AKDP), and Trans Jogja routes, has the potential to contribute significantly to ambient air pollution due to vehicle emissions. This study focuses on identifying carbon monoxide (CO) concentrations and analyzing the spatial distribution of CO levels within the Terminal Jombor area. A quantitative approach was employed through direct observation and measurements at three monitoring points. The results indicate that the highest CO concentration was recorded at Point 1 on the third day of observation (weekday), reaching 10,883.2 µg/Nm³, exceeding the ambient air quality standard of 10,000 µg/Nm³. Meanwhile, the highest average CO concentration was observed at Point 3, with a value of 2,446 µg/Nm³. This point is located near the terminal exit area, where vehicles tend to idle before accelerating, thereby increasing CO emissions. Furthermore, CO concentrations on weekdays were found to be higher than those recorded on weekends. Spatial distribution analysis revealed that Points 2 and 3 fall into the moderate to high concentration categories. These findings indicate the need for intervention by relevant authorities to mitigate potential health impacts associated with carbon monoxide exposure in the Terminal Jombor area.
