Abstract

The emission factor (EF) describes the relationship between pollutants released into the atmosphere and associated activities. Developing specific EFs is essential for accurate emission calculations in the industrial sector, particularly in coal-fired power plants (CFPPs), a major source of emissions in Indonesia. This study aims to develop specific CO2 EFs for CFPPs in Indonesia by analyzing the influence of power plant characteristics, such as technology type and age, on the EF values. The EFs, expressed in tons of CO2 per unit of energy produced (t TJ-¹), are based on data from 153 units across 66 CFPPs in Indonesia. Five technology types were included in the analysis: ultra-supercritical, super-critical, subcritical-pulverized coal combustion, subcritical-fluidized bed combustion and subcritical–stoker. The study compares the resulting CO2 EFs with the IPCC-2006 default value for sub-bituminous coal and Indonesia’s national EF for medium-quality coal. The average CO2 EF for Indonesian CFPPs was 100.16 t TJ-1, higher than the IPCC-2006 default value (96.1 t TJ-1) but slightly lower than Indonesia’s national EF (100.575 t TJ-¹). A statistical test revealed significant differences between technology and age groups, but post-hoc analysis showed no strong correlation was found between these characteristics and the EF values within specific groups. This indicates that the EF, based on fuel characteristics, is not directly influenced by these plant characteristics. It is hoped that the CO2 EF values obtained from this study will better represent actual conditions, provide a more accurate emission calculations and supporting the development of better emission inventories for cleaner energy generation.

Abstract

Eco-enzyme represents a biological solution derived from the fermentation of organic materials, evaluated for its effectiveness in industrial wastewater treatment. This study examines  to investigate the effectiveness of eco-enzymes in improving the quality of industrial wastewater by analyzing their impact on four specific types of liquid waste: landfill leachate, tofu wastewater, batik wastewater, and laundry wastewater. Samples were treated with eco-enzyme at specific concentrations and incubated for 5 days, followed by chemical analysis. Eco-enzyme reduced ammonia levels in landfill leachate by 57% to 8.83 mg/L, though COD and BOD values rose to 18,114.6 mg/L and 46,709 mg/L, respectively, exceeding effluent standards. In tofu wastewater, COD and BOD decreased by 72% and 75% to 4,189.68 mg/L and 2,395.3 mg/L, respectively, but remained above regulatory limits. Batik wastewater showed increases in most parameters, with COD and BOD reaching 6,838.85 mg/L and 3,193.5 mg/L. For laundry wastewater, surfactants decreased by 55% to 12.97 mg/L, but BOD and TSS increased. These findings indicate that while eco-enzyme can reduce specific pollutants like ammonia and surfactants, its application can also elevate COD and BOD levels in some cases. Additional treatment processes, such as aeration or coagulation, are required to achieve effluent standards. Despite its limitations, eco-enzyme holds potential as an environmentally friendly option for industrial wastewater management when integrated with complementary technologies.

Abstract

The cement industry is one of the sectors that produces carbon dioxide (CO2) emissions due to its raw material processing and energy requirements. CO2, as a greenhouse gas (GHG) emission, contributes to global warming, leading to environmental, health, and economic losses. To address these issues, Indonesia is committed to reducing GHG emissions in the industrial sector by 2050. To effectively plan for the reduction of GHG emissions generated by companies, this study aims to quantify emissions from a cement company, representing the cement industry in Indonesia, to understand the current state of the company's carbon footprint and identify feasible mitigation measures. The cement industry utilizes a GHG quantification system to calculate emissions from raw material processing, thermal energy consumption, and electricity purchases. The calculation results from a cement company are used for system dynamics modeling with Vensim PLE software for the period from 2021 to 2050, under business-as-usual (BAU) conditions with various emission reduction strategies. The results show that GHG emissions under BAU conditions with emission reduction strategies do not achieve carbon neutrality by 2050. More intensive adoption of decarbonization technologies, research on process optimization, and government policies such as carbon taxes and carbon trading are required to achieve carbon neutral goals.

Abstract

Communal wastewater treatment plants (WWTPs) have been established in the Province of Aceh, mostly in Banda Aceh City as the capital and other parts of the province, to address significant environmental risks posed by wastewater originating from domestic activities. However, limited coverage, poor effluent quality, and insufficient community involvement persist. This research assesses public participation and willingness to engage in wastewater management practices. A quantitative survey was conducted with 148 Banda Aceh and Aceh Barat respondents, selected through multi-stage random sampling. The first stage in respondent selection is based on area. Banda Aceh City, the provincial capital, was chosen as the initial location for the respondents’ residence, followed by Meulaboh as the regency capital. The second stage involves respondents who have household businesses (which generate domestic waste, in this case, owners of laundry and vehicle washing businesses) and those who do not have businesses. The survey explored respondents' perceptions of environmental pollution, awareness of wastewater regulations, and their readiness to participate in management efforts. The findings reveal that 77.7% of respondents are willing to join in wastewater management initiatives, with 52.21% expressing a willingness to attend community meetings and 18.14% agreeing to pay fees for communal WWTP services. Key factors influencing participation include awareness of environmental issues, positive perceptions of communal WWTPs, and the belief that the government should provide wastewater treatment infrastructure. The study concludes that increasing public awareness and involving communities in policy formulation is crucial for improving wastewater management in Aceh. These insights can guide local governments in developing effective regulations and fostering sustainable community engagement in environmental protection efforts, potentially leading to a healthier and more sustainable environment for the people of Aceh.

Abstract

Groundwater in DKI Jakarta is subject to microbiological contamination. Approximately 32% of the population in DKI Jakarta relies on groundwater as an alternative source of clean water, highlighting the urgent need to address and prevent contamination. This study aims to investigate the effect of the separation distance between septic tanks and wells on the levels of Total coliform (TC), Escherichia coli (EC), and organic parameter contamination in shallow groundwater. Groundwater quality data, including TC, EC, and organic parameters from 265 monitoring points in DKI Jakarta, was obtained from the Jakarta Environment Agency in 2022. A quantitative descriptive approach, incorporating spatial mapping of bacterial and organic contamination using Geographic Information System (GIS) tools, was employed. MANOVA analysis using SPSS 26 was conducted to determine the relationship between septic tank distances and shallow water contamination levels. Results indicate that the separation distance between septic tanks and wells significantly influences TC and EC contamination in Jakarta Pusat, Jakarta Timur, and Jakarta Barat. Organic contamination, however, is significantly affected only in Jakarta Pusat and Jakarta Timur. In contrast, Jakarta Utara was identified as the most contaminated region, with 84% of groundwater samples showing TC contamination, 55% exhibiting Escherichia coli (EC) contamination, and 69% affected by organic pollution. However, these contaminations were not proven to be influenced by the proximity of septic tanks. This is likely due to the area's coastal location, where hydrogeological conditions and diverse pollution sources play a more significant role in groundwater contamination. Improvements in sanitation infrastructure could significantly enhance groundwater quality, particularly in highly vulnerable areas such as Jakarta Utara.

Abstract

Peat water is water produced from decaying trees and plants that contain Fe metal with a high content of organic substances. Therefore, effective and efficient peat water treatment is needed to make it suitable for consumption. Bentonite is a natural source of adsorbent but has a fairly low adsorption activity, so bentonite needs to be activated to increase its adsorption ability. Thermal activation was chosen due to its environmentally friendly process and can increase the surface area and adsorption ability of bentonite. This study was conducted to see the effect of bentonite thermal activation with temperatures of 200, 300, 400 and 500˚C in reducing Fe metal content, organic matter, TDS and pH of peat water. The results show that thermal activation of bentonite can reduce the content of these compounds. Thermal activation of bentonite at 500˚C reduced Fe metal content with 66% efficiency and 0.08 mg/g adsorption capacity, 89.6% organic matter with 24,60 mg/g adsorption capacity and TDS 27 mg/l.
