Abstract

Waste water from the nickel mining process has the potential to contaminate the environment due to the presence of hazardous metals such as chromium (Cr) in the form of Cr(VI) and Cr(III), iron (Fe), nickel (Ni) and other heavy metals. These substances are of great concern because of their toxicity, which can have adverse effects on ecosystems and human health. This study was conducted to investigate the effects of UV-C lamp light intensity, contact time and RIPT-ZnO weight on the removal of hexavalent chromium (Cr(VI)) from nickel wastewater. The method used in this research involved immobilisation of photocatalysts on resin with RIPT concentrations of 5g, 10g and 15g and variations in UV-C lamp light intensity of 8W, 18W and direct sunlight. The contact times tested were 0 minutes, 30 minutes, 60 minutes, 120 minutes and 180 minutes, with the focus of the analysis on the Cr(VI) concentration. The results showed that increasing RIPT dosage resulted in higher Cr(VI) removal percentages. The highest Cr(VI) removal was achieved with a 15 gram RIPT dosage, especially when ZnO was used. The optimum contact time for maximum Cr(VI) removal was 180 minutes, indicating that the longer the wastewater is exposed to RIPT, the higher the removal rate. The study found that the use of ZnO in the RIPT technology achieved the highest Cr(VI) removal efficiency, reaching 96%.

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

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

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.

Abstract

Greenhouse gas (GHG) emissions from the industrial sector have a significant impact on global climate change. To assess the overall environmental impact, an analysis capable of mapping emissions from various operational activities is required. This study aims to analyze GHG emissions in a manufacturing company that focuses on turbocharger system assembly and services using the Life Cycle Assessment (LCA) method. The analysis was conducted with reference to the 2006 IPCC Guidelines and openLCA software, with the scope of research covering the transportation and energy sectors within the company. The inventory results show that the energy sector is the main contributor to emissions, with the largest impact category being climate change (GWP 100a). Next, a scenario analysis was conducted, namely real conditions, the use of solar panels, the use of diesel fuel, and a mixture. A comparison of the scenarios showed that the use of renewable energy in the form of solar panels could significantly reduce GHG emissions compared to the current conditions. This study confirms that the application of LCA can provide a quantitative picture of the potential environmental impact and serve as a scientific basis for formulating GHG emission management strategies in the industrial sector.
