Abstract

Landfills generate methane gas (CH₄) as a result of the anaerobic decomposition of organic waste. This gas has the potential to serve as a renewable energy source if managed properly. This study aims to analyze the methane gas emission potential from the Sekoto landfill using the Landfill Gas Emission Model (LandGEM) and convert it into electricity and LPG. Annual waste generation data from 2021 to 2026 was used as input for the LandGEM model to estimate methane gas emissions. The modeling results indicate that peak methane production will occur in 2027, with a total of 4,247,951 m³/year. The potential electrical energy generated from this methane gas reaches 349,421,156.64 kWh per year, equivalent to 39,888.26 MWh. Additionally, the potential conversion of methane gas to LPG is estimated at 1,954,057.46 kg of LPG per year or approximately 5,353 kg per day. Utilizing methane from the Sekoto landfill as an alternative energy source not only contributes to renewable energy supply but also reduces greenhouse gas emissions that impact global warming. With a more efficient gas harvesting system and adequate processing infrastructure, methane gas can be converted into a more beneficial energy source for the community. This study confirms that optimizing landfill gas management can enhance energy sustainability while mitigating the environmental impact caused by methane emissions.

Abstract

The plastic recycling industry generates wastewater that poses a potential threat to aquatic environments if not managed optimally. Performance evaluation of Wastewater Treatment Plants (WWTP) is typically conducted partially by comparing outlet parameters against effluent standards, often failing to depict water quality conditions holistically. Therefore, this study employs the Water Quality Index (WQI) approach using the Canadian Council of Ministers of the Environment (CCME) method to evaluate the performance of PT X's WWTP in East Java. This research utilized secondary data from inlet and outlet wastewater quality tests over 23 months (January 2024–November 2025), covering 10 parameters. Analysis was conducted by calculating removal efficiency and determining factors F1 (scope), F2 (frequency), and F3 (amplitude) as the basis for the WQI-CCME calculation. The results indicate that the WWTP achieved high efficiency (>80%) in reducing dominant parameters such as TSS, TDS, BOD, and COD. However, violations of effluent standards were still observed in certain parameters. The obtained WQI-CCME value was 69,30, categorized as "Fair" with a moderate level of violation. These findings demonstrate that although the WWTP meets regulatory standards, the WQI-CCME approach provides a more comprehensive assessment of performance. Optimization of advanced treatment units is recommended to improve effluent quality and sustainable WWTP performance.

Abstract

Malang Regency is known as a strategic location with considerable potential as a tourism destination in Indonesia. According to data released by the Central Bureau of Statistics, Malang Regency has recorded 267 tourist destinations spread across 33 districts. This study uses data from one water tourism destination, referred to as Tourism Site X, which focuses on the management and development of recreational areas, including swimming pools, bathing facilities, water attractions, artificial lakes, as well as the management of recreational parks and family facilities such as playgrounds, seating areas, and recreational and educational facilities. Tourism Site X is located in Pakis District, Malang Regency. The reuse of treated wastewater as a non-potable water source for irrigating green open spaces represents a crucial strategic approach to conserving water resources, particularly in water tourism areas such as Tourism Site X, which require substantial water supplies. In practice, the wastewater generated in Tourism Site X mainly originates from domestic sources, including activities such as cleaning swimming pool areas and animal enclosures, toilet usage, and food court operations. This study aims to assess whether the quality of treated wastewater from the wastewater treatment process at Tourism Site X complies with the required standards for green open space irrigation, in accordance with the Regulation of the Minister of Environment/Environmental Control Agency of the Republic of Indonesia Number 11 of 2025 concerning Wastewater Quality Standards and Wastewater Treatment Technologies for Domestic Wastewater, as well as to identify parameters that need to be reduced or eliminated.

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.
