Abstract

The textile industry's wastewater is mainly comprised of synthetic dyes. Synthetic dyes are complex organic compounds that offer significant resistance to environmental conditions and highly harmful to ecological systems. The decolourization process can be enhanced by biological agents. The brown rot fungus, Aspergillus niger, is a biological agent with potential for the decolorization of synthetic colours. This article discusses information and literature review of investigations on the decolorization capacity of synthetic dyes by Aspergillus niger fungi. The literature review involved the analysis of qualitative data, observation, and the derivation of conclusions from previous research journals. The study's results demonstrate Aspergillus niger fungi significant potential of synthetic dye removal can up to 90% via simultaneous biodegradation and biosorption processes. Many variables effect the removal procedure, including pH, agitation settings, temperature, initial dye concentration, and nutritional content.

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.

Abstract

This study aims to evaluate the efficiency of the electrocoagulation method in reducing TDS and hardness levels, as well as to analyze the effects of inter-electrode distance (1; 1.5; and 2 cm), applied voltage (15; 20; and 25 V), and contact time (20; 40; 60; and 80 minutes). The initial concentrations of brackish water samples were measured prior to treatment, and the samples were subsequently processed using an electrocoagulation reactor. The highest TDS removal efficiency was achieved at an inter-electrode distance of 1.5 cm, reducing the concentration from an initial 5526 mg/L to 1225 mg/L (77.83%). Under the same condition, hardness decreased from 580 mg/L to 164 mg/L (71.72%). Regarding voltage variation, the greatest reduction in TDS and hardness was observed at 25 V, reaching 1090 mg/L (80.28%) and 176 mg/L (69.66%), respectively. The optimal treatment time was 60 minutes, resulting in a TDS reduction to 1100 mg/L (80.09%) and a hardness reduction to 186 mg/L (67.93%). Inter-electrode distance, applied voltage, and contact time were found to have a significant effect on the electrocoagulation process in reducing TDS and hardness levels, as confirmed by ANOVA analysis.

Abstract

Plastic recycling industries generate wastewater with complex characteristics requiring effective treatment systems to meet environmental quality standards. This study aimed to evaluate the performance of Wastewater Treatment Plant (WWTP) at plastic recycling facilities (PRF) through analysis of wastewater physicochemical parameters. Sampling was conducted at four sampling points: pump it (PI), floating clarifier 1 (FC1), floating clarifier 2 (FC2), and floating clarifier 3 (FC3) under two different operational conditions. The physicochemical parameters measured included COD, TSS, temperature, turbidity, TOC, and pH. The investigated WWTP consisted of three main units: tube flocculator, electrocoagulation (EC), and moving bed biofilm reactor (MBBR). Results showed that tube flocculator had the best performance with removal efficiency of TSS 94.7%, turbidity 97.3%, and COD 82.4%, while successfully neutralizing pH from 11.84 to 7.24. EC unit showed variable performance between operational and non-operational conditions, with BOD removal efficiency of 42.9% and turbidity 40.9% under operational conditions. MBBR with HRT 14.5 hours showed BOD removal efficiency of 41.7% and COD 13.8%. However, the final effluent quality did not meet the standards set in Minister of Environment Regulation No.5 of 2014, particularly for BOD and COD parameters which still exceeded the permitted limits. This study provides comprehensive evaluation of WWTP performance in plastic recycling facilities and identifies the need for further optimization to improve wastewater treatment effectiveness.

Abstract

Carbon dioxide (CO₂) emissions from the energy sector are a major contributor to global warming, thus becoming a serious challenge in achieving sustainable development. Most industrial areas in Indonesia still rely on electricity supply from natural gas-fired Steam Power Plants (PLTU) which contribute to carbon emissions. Based on these problems, this study aims to: (1) evaluate the existing conditions of the integration of Solar Power Plants (PLTS) with Private Power Generation systems, (2) calculate the potential CO₂ emission reduction from the use of PLTS, and (3) analyze the Economic Value of Carbon (NEK) based on national policies. The method used refers to the 2006 Intergovernmental Panel on Climate Change (IPCC) guidelines with a Tier 2 approach, as well as NEK calculations based on the Regulation of the Minister of Energy and Mineral Resources (Permen ESDM) No. 16 of 2022. The results of the study show that the current PLTS integration uses an On-Grid system with a capacity of 30% of the connected capacity. This condition causes the emission reduction achieved to be still limited due to regulatory restrictions. To achieve optimal emission reductions, a transition to an off-grid system is necessary. The economic value of carbon from solar power plant utilization shows a surplus of IDR 812,463,000 per year. Further research is recommended to examine hybrid system scenarios, long-term economic analysis, and the impact of carbon incentive policies on accelerating renewable energy adoption in the industrial sector.

Abstract

Chromium (Cr) is a heavy metal that is toxic, persistent, and potentially carcinogenic. Cr is widely produced from industrial activities such as leather tanning, textiles, and metal plating, making its presence in liquid waste a serious concern. This study aims to investigate the efficiency of reducing Cr concentrations in water using a sugarcane bagasse-based adsorption method, as well as to determine the effect of adding humic acid on enhancing adsorption effectiveness. The study was conducted in batch mode at the Water Quality Laboratory of the Environmental Engineering Program at the University of Islam Indonesia. The parameters varied included pH, contact time, and initial Cr concentration, while the adsorbent characterization was performed using FTIR and SEM. In this study, sugarcane bagasse was used as an adsorbent that had been carbonized at 350°C and sieved to a 50-mesh size. Cr concentration was anlyzed using SSA. Characterization result showed the presence of hydroxyl (-OH), carbonyl (C=O), and aromatic groups in sugarcane bagasse, as well as a porous surface morphology that supports the adsorption process. Optimal conditions were achieved at pH 3, contact time 1440 minutes, and Cr concentration 5 mg/L. The addition of humic acid was found to increase adsorption efficiency by 22,5%. The apporpriate ishoterm model is Langmuir with a maximum adsorption capacity of 1,52 mg/g, while the adsorption kinetics follow the pseudo second order model with rate constant K of 0,0496 g/mg·min.

Abstract

Domestic activities at the ITERA TB 2 student dormitory generate greywater containing significant levels of Chemical Oxygen Demand (COD) and Total Suspended Solids (TSS), alongside specific pH levels. The direct discharge of this untreated wastewater poses a severe threat to local ecosystems. To address this issue, this study investigates electrocoagulation—an electrically-driven coagulation process—as an alternative treatment method to mitigate pollutant concentrations. The research evaluated the reduction of COD and TSS (dependent variables) across varying applied voltages (10, 20, and 30 V) and contact times (30, 60, and 90 minutes) as independent variables. The results indicated that the optimum treatment occurred at 30 V with a 90-minute contact time. Under these conditions, COD was successfully reduced from 115 mg/L to 11.5 mg/L, and TSS decreased from 103 mg/L to 9.5 mg/L, accompanied by a pH shift from 7.11 to 9.3. These findings demonstrate the efficacy of the electrocoagulation method in significantly reducing greywater pollutants.
