Abstract

The fertilizer industries in East Java Province has increased in scale of production, area and human resources in line with the increase in fertilizer demand in Indonesia by 5.67%. It causes increased emissions into the atmosphere which will affect health and the environment. Therefore, an air dispersion simulation was carried out to determine the maximum level of emissions released. This study uses a modeling approach with Aermod View software to simulate the process of dispersion of CO2, NOX, and TSP air emissions in the distribution of emissions. The results of the dispersion distribution model for SO2, NOX, and TSP emissions are at a distance of 500 - 600 m from the emission source. The dispersion simulation results of the SO2 show the highest concentration of 7.34 µg/m3. The dispersion simulation results of the NOX show the highest concentration of 9.791 µg/m3. Also, the results of the TSP show the highest concentration of 1.22 µg/m3. Based on Republic of Indonesia Government Regulation no. 22/2021 Appendix VII concerning Ambient Air Quality Standards for the SO2 of 150 µg/m3, the NOX of 200 µg/m3, and the TSP of 230 µg/m3, each emission parameter still meets the established emission quality standards.

Abstract

The drainage system is critical infrastructure for managing stormwater runoff in densely built urban areas, including higher education institutions. This study aims to evaluate the capacity performance of the existing drainage channels in the UPN "Veteran" Jawa Timur campus area. The evaluation was conducted through two main stages: hydrological analysis using the rational method to estimate the design runoff discharge for a 10-year return period, and hydraulic analysis using Manning's equation to calculate the channel cross-sectional capacity in accordance with Permen PU No. 12 of 2014. Based on the assessment of 43 drainage channels, the results showed that 33 channels (76.7%) are still functioning optimally and capable of accommodating the design discharge. Conversely, 10 channels (23.3%) were identified as having insufficient capacity. This capacity deficit was triggered by initial designs that did not accommodate the 10-year return period flood discharge, increased runoff coefficients due to massive pavement development, and effective cross-section narrowing caused by sedimentation. To mitigate inundation issues, this study recommends redesigning the failing channels using an economical hydraulic cross-section, accompanied by periodic normalization and dredging for functional channels. The findings of this study are expected to serve as technical guidelines for the optimal and sustainable management of campus drainage infrastructure.
