Abstract

Anaerobic Baffled Reactor (ABR) systems have only been utilized to reduce pollutant compounds in wastewater. Anaerobic conditions in ABR can double as an anode chamber in Microbial Fuel Cells (MFCs) which require anaerobic conditions. This study aims to test the ability of COD and TSS removal in tofu wastewater and the potential electricity generated from a combination unit of ABR and MFCs. The experiment was conducted on a laboratory scale using a continuous system for 96 hours. ABR reactor was made consisting of 5 compartments, where the second compartment was installed anode for MFCs. The cathode chamber of the MFCs system was made separate from the ABR reactor and filled with electrolyte solution. The anode chamber in the ABR and the cathode chamber are connected by a salt bridge. Electrodes used in MFCs are zinc as anode and copper as cathode. The removal of pollutants in tofu wastewater reached 55.85% for COD and 88.68% for TSS. The electrical potential of MFCs increases along with the increase of organic matter removal in wastewater. The electric voltage generated reached 0.94 V and electric current 0.40 mA. The power density generated in this MFCs system reached 94 mW/m².

Abstract

The increase in operational activities at one of the airports in East Java has led to elevated noise levels in the surrounding areas, particularly in residential zones. This study aims to analyze the conformity of noise levels with environmental quality standards using a spatial modeling approach. The method applied is descriptive quantitative, employing spatial analysis based on secondary data obtained from the Environmental Management and Monitoring Plan (RKL-RPL) documents. Noise data were examined from five monitoring points and visualized through maps using GIS software. The results indicate that most observation points recorded noise levels exceeding the threshold limits stipulated by Ministry of Environment Decree No. 48 of 1996 and were also found to be inconsistent when compared to area classifications based on the WECPNL method. The implications of these findings highlight the necessity for evaluating the effectiveness of RKL-RPL implementation, strengthening supervisory roles, and formulating mitigation strategies, such as the development of green open spaces and the adoption of environmentally friendly flight paths, to minimize noise impacts on surrounding communities.

Abstract

River basins are the most fundamental thing in managing natural water resources in Indonesia. Based on the Regulation of the Minister of Public Works and Public Housing No. 4/PRT/M/2015 concerning standards and ratification of river basins, Indonesia is divided into 128 river basins. The division of East Java is divided into 5 River Basins, namely the Madura Islands WS, Welang - Rejoso WS, Bondoyudo - Bedadung WS, Pekalen-Sampean WS, and Baru - Bajulmati WS. The condition of the river basin is increasingly causing various problems. The methods applied include a qualitative approach. The quantitative approach is carried out through the use of questionnaires filled out by participants followed by conducting a literature review. The results obtained from 48 respondents that the problems in the East Java river basin occurred due to flooding with a percentage of 66.67%, garbage 14.58%, waste 16.67%, and erosion 2.08%. From these problems there are solutions using biotechnology, river ecosystem restoration, wastewater management, dam construction with good infrastructure, the need for river basin monitoring sensors. Other essential factors in the socialization of education and community involvement are NGOs and government regulations.

Abstract

This study aimed to evaluate the performance of PVDF and PVC ultrafiltration membranes coated with Al2O3 in removing total dissolved solids (TDS) from Sungai Jagir river water after a pre-treatment adsorption using Granular Activated Carbon (GAC). The adsorption process was conducted for 10 minutes before the water was filtered through the membranes under various operating pressures (1, 1.5, and 2 bar) and operation times (0.1–0.5 h). The results showed that both membranes exhibited an increase in TDS rejection efficiency with longer operation time, while pressure had a limited effect. The PVDF membrane demonstrated consistently higher TDS rejection compared to PVC, suggesting that membrane surface properties influence solute removal efficiency. Statistical analysis using three-way ANOVA revealed that operation time had a significant effect on TDS rejection, whereas pressure did not show a notable impact. These findings indicate that contact duration between water and membrane plays a crucial role in reducing TDS in river water through ultrafiltration.

Abstract

Klotok landfill is a final waste processing site in the City of Kediri that has been operating since 1992 to manage waste in the Kediri City and its surroundings. Waste management activities at the Klotok TPA generate emissions from the waste pile and heavy equipment activities. This study aims to determine the air quality at the Klotok Landfill through direct measurements to obtain results with a more accurate approach. The measurement results will then be modeled with AERMOD software to determine the distribution of these pollutants to the area around the TPA. In this study, air quality measurements were carried out at three points in the Klotok TPA to determine the level of pollution that occurred. Air quality is measured directly using a High Volume Air Sampler (HVAS), Impinger, and Sound Level Meter. Air pollutant parameters measured included Nitrogen Dioxide (NO2), Total Suspended Particulate (TSP), Sulfur Dioxide (SO2), Oxidants (O3), Carbon Monoxide (CO), Lead (Pb), Non-Methane Hydrocarbons (NMHC), Particulate Matter 2.5 (PM2.5), PM10, Ammonia (NH3), and noise. The measurement results show that the CO parameter exceeds theambient air quality standards of PP No. 22 Year 2021 at the weighbridge and the landfill 3 with values of 13,750 and 18,750 µg/Nm3 respectively,while other parameters still meet the quality standard. The model with AERMOD software shows the dispersion of CO nearby the landfill area occurs quickly so that since the first 100 meters the CO concentration has been dispersed to below 10 µg/Nm3. CO concentrations at a distance of more than 1 km from the Klotok TPA are generally below 1 µg/Nm3.

Abstract

The Jagir River has experienced a decline in water quality due to domestic and industrial activities, with pollutant parameters such as TDS, turbidity, and total coliform exceeding the quality standards. This study aims to analyze the effect of operating time and pressure variations of PVC- TiO2 ultrafiltration membranes on the removal capability of TDS, turbidity, and total coliform parameters as well as the flux rate of the membrane. The addition of TiO2 aims to increase the flux rate of the UF membrane. This research method involves adsorption pre-treatment using granular activated carbon (GAC) before the ultrafiltration process with varying pressures (1; 1.5; 2 bar) and operating time (15 – 75 minutes). The results showed that adsorption pre-treatment was able to reduce turbidity (95.45%), total coliform (59.93%), and TDS (18.89%). The combination of 2 bar pressure with an operating duration of 75 minutes resulted in the highest removal efficiency for all three parameters, namely total coliform (100%), turbidity (96.90%), and TDS (18.84%). TiO2 coating increases the membrane flux rate at the start of operation, especially at high pressures, but over time it decreases drastically due to fouling.
