Abstract

Enim river flows within several sub-districts in Muara Enim Regency, including Semendo Darat Laut, Semendo Darat Tengah, Semendo Darat Ulu, Tanjung Agung, Lawang Kidul, and Muara Enim. This study examines changes in the water quality of the Enim River due to domestic wastewater discharges and the presence of the coal mining industry and household industries. Water samples were taken from 4 sampling stations along the Enim River in 2018 and 2023. Data consisted of results of physical, chemical, and microbiological parameters. The status of river water quality was assessed from the pollution index. The results of Enim River surface water quality measurements showed that the parameters of total suspended solids, Dissolved Oxygen, iron (Fe), copper (Cu), oil, and grease concentrations had breached the criteria set for Class II water quality, referring to Government Regulation of the Republic of Indonesia Number 82 of 2001. The results showed that there has been a change in the water quality status of Enim River from 2018 to 2023. The river water pollution index was (1.43-2.47) in 2018 and (1.49-3.85) in 2023 (lightly polluted). Comprehensive water treatment and preventive measures are necessary to manage and mitigate additional pollution in the Enim River.

Abstract

In the sixth assessment report, the IPCC indicates that global temperature increased by 1.11 (±0.13) degrees Celsius in 2019 due to 6.5 gigatons of CO2eq of greenhouse gas emissions into the atmosphere. The power sector is a major global greenhouse gas emitter, particularly in Indonesia. Indonesia’s electricity sector emitted 149.90 million tons of CO2eq greenhouse gas in 2020, which is expected to increase to 158.30 million tons of CO2eq in 2021. Indonesia has committed to reducing greenhouse gas emissions according to the Paris Agreement. The Paris Agreement has been ratified into national law, accommodating Indonesia’s roadmap to net zero by 2060. The emissions reduction target was published in 2022 through the enhanced Nationally Determined Contribution (NDC). This study aims to analyze the impact of climate policy in Indonesia’s electricity sector to meet the net zero emissions target by 2060. Projection and calculation in this study were conducted using the Low Emissions Analysis Platform (LEAP). Data from 2020, including electricity demand, existing capacity, energy production, energy intensity, lifetime, and capacity factor, were used to support LEAP analysis. The data were obtained from the PLN statistical book, PLN sustainability report, Indonesia’s statistical book, and climate change mitigation and adaptation reports in Indonesia. This study developed three climate scenarios, including business as usual (BAU), sustainable development (SD), and low-carbon development (LCD). These scenarios draw upon current climate policies that have various impacts on electricity generation in Indonesia. Based on LEAP analysis, by 2060, energy demand is expected to increase to 300.36 MTOE (BAU), 200.93 MTOE (SD), and 76.97 MTOE (LCD). Consequently, each climate scenario requires an increase in installed capacity to 821.82 GW (BAU), 727.06 GW (SD), and 334.58 GW (LCD). The renewable energy mix is projected to be 21% (BAU), 69% (SD), and 100% (LCD). Each scenario requires investment to develop capacity to meet energy demand. The investment cost is estimated to be 1,671.58 million USD (BAU), 1,537.64 million USD (SD), and 816.51 million USD (LCD). GHG emissions are projected to rise to 1,746.31 million tons of CO2eq (BAU) and 264.39 million tons of CO2eq (SD). However, the LCD scenario expects to achieve net zero emissions by 2060.

Abstract

Urbanization is the result of persistent population increase, which turns formerly agrarian areas into industrial and service-based hubs. This change prompts concerns about environmental degradation, including flooding, declining agricultural output, and air pollution, as well as a rise in demand for residential real estate, a limited resource. Goal 11 of the Sustainable Development Agenda, ”Building Inclusive, Safe, Resilient, and Sustainable Cities and Communities” addresses these problems. However, a comprehensive LSA incorporating local climate aspects has not been conducted for Serang Regency, an area with significant population growth and diverse land characteristics. This study aims to map the spatial distribution of suitable residential land in Serang Regency; evaluate the suitability of current residential areas; and assess the alignment of settlement plans with suitability criteria in the spatial plan. Findings reveal that 65.5% of Serang Regency is suitable for residential use, while 32% is unsuitable. Currently, 71.2% of settlements are in suitable areas, and 28.2% are in unsuitable ones. Future settlement plans show 90.7% alignment with suitable areas. These results indicate that, while spatial planning in Serang Regency has generally guided appropriate residential development, some areas still require attention for sustainability. This study provides valuable insights for policymakers aiming to foster sustainable, safe, and comfortable living environments.

Abstract

Community-based waste management in the PT. Bukit Asam Township, Tanjung Enim, is essential. This study involved 67 respondents residing in the Township. A mixed-method approach was used, including interviews, observations, and SWOT analysis. The results indicate that residents are actively engaged in waste containment, with most households (85%) disposing of all waste without sorting. Only a small percentage reuse items (5%) and compost (2%). The average waste generated per socioeconomic group exceeds the standards set by SNI 3242-2008. Community-based waste management at PT. Bukit Asam has the potential for success due to active participation and company support. The SWOT analysis reveals strengths in participation, company support, education, and a structured system but weaknesses in dependence on participation and funding, and limitations in human resources and infrastructure. Opportunities include government support, new technologies, and collaboration with NGOs, while threats arise from policy changes, social issues, regulations, environmental impacts, and disasters. Improvement strategies include initial assessments, stakeholder mapping, awareness enhancement, facility provision, supervision, monitoring, incentives, periodic evaluations, and continuous innovation. With these strategies, the program is expected to be effective and sustainable, address waste issues, create new economic opportunities, and serve as a model for other communities.

Abstract

The growth rate in agro-industrial sectors has both positive and negative effects on technological, social, and economic development. Agro-industry production generates substantial volumes of wastewater, primarily from the aqueous discharges of its manufacturing processes. Some of this wastewater contains harmful pollutants that endanger human life, health, and the sustainability of the environment and ecosystem. For example, wastewater from the bioethanol industry contains high concentrations of organic pollutants and recalcitrant compounds, with COD and BOD values exceeding 50,000 mg/L and 30,000 mg/L, respectively. The Fenton process is an oxidation method that generates hydroxyl radicals through the reaction between H2O2 and Fe2+ ions. These hydroxyl radicals are highly effective at breaking down recalcitrant compounds. In this study, a comparative analysis of recalcitrant wastewater treatment using Fenton and photo-Fenton oxidation processes was conducted. The effects of dilution factors, or initial concentrations of recalcitrant wastewater (1:25, 1:50, and 1:75), were examined. Higher dilution ratios enhanced the degradation of COD and BOD levels in wastewater, with the optimal dilution factor for both processes being 1:75. Under optimal conditions, the removal efficiencies for COD, BOD, potassium, and phenol were in the range of 72.29-99.99%. The photo-Fenton process demonstrated higher removal efficiency compared to the Fenton process. The conclusion from this study suggests that the photo-Fenton process could be successfully employed as an advanced treatment method for effectively breaking down recalcitrant wastewater. These findings could be useful for adapting these processes to field-scale applications.

Abstract

This study investigates the synthesis and characterization of ZnAl-layered double hydroxide (ZnAl@LDH) composites modified with Eucheuma cottonii (EC) for the adsorption and regeneration of congo red (CR) dye. The ZnAl@LDH was synthesized using a co-precipitation method, and the composite with EC was prepared via hydrothermal techniques. The structural properties of the composites were analyzed using XRD and FTIR. Adsorption experiments were conducted to determine the effects of pH, contact time, concentration, and temperature on dye removal. The adsorption kinetics followed the pseudo-second-order (PSO) model, while the isotherm data best fitted the Freundlich model, indicating multilayer adsorption. The ZnAl@EC composite demonstrated superior adsorption capacity (243.902 mg/g at 40 °C) compared to ZnAl@LDH and EC. Thermodynamic studies revealed that the adsorption process was spontaneous and endothermic for ZnAl@LDH and EC but exothermic for ZnAl@EC. The regeneration study showed that ZnAl@EC retained significant adsorption capacity even after seven cycles, indicating its potential for practical applications in wastewater treatment.

Abstract

This study explores the conversion of Areca fruit peel into carbon-based materials biochar (BC) and hydrochar (HC) for use as adsorbents in synthetic dye removal from wastewater. Conversion was achieved through pyrolysis for BC and hydrothermal carbonization (HTC) for HC. X-ray diffraction (XRD) analysis confirmed carbon formation, with both HC and BC showing an amorphous characteristics. FTIR analysis identified hydroxyl, carboxyl, acid, and ester functional groups in BC, HC and Areca fruit peel materials that are essential for adsorption. BET surface area measurements showed 82.584 m2/g for BC and 77.618 m2/g for HC. Adsorption experiments demonstrated CR removal capacities of 40.515 mg/g for HC and 40.616 mg/g for BC, significantly surpassing the 23.168 mg/g capacity of untreated Areca fruit peel. Over three regeneration cycles, both BC and HC retained structural integrity, highlighting their potential as reusable adsorbents for dye removal. These results suggest that Areca fruit peel-derived BC and HC are promising, sustainable adsorbents for wastewater treatment, particularly in mitigating environmental impacts from industrial dyes.

Abstract

Hospital wastewater contains a high concentration of ammonia that exceed the predetermined quality standards and can cause pollution to the environment. Therefore, the treatment of hospital wastewater is required prior to being released to the environment. Effective ammonia removal process has been developed by using a combination of sponge filtration pretreatment, followed by adsorption using activated carbon from waste of tea leaves, and nanofiltration using ceramic membrane as the final process. Experiment results show the highest effectiveness of ammonia removal of 70% by using filtration only. Effectiveness is increases up to 95% by a combination of filtration and adsorption. A maximum effectiveness of 100% is achieved when using a combination of filtration, adsorption, and nanofiltration. This combination produces an optimal condition for the ammonia removal by using 3 L/min flowrate, adsorbent mass 140 g, and operating time 15 minutes at which the ammonia concentration is 0.08 mg/L. This concentration is below the standard of allowable ammonia concentration of 0.1 mg/L.

Abstract

The contamination of wastewater with synthetic dyes, particularly anionic dyes, poses a significant environmental challenge due to their persistence and difficulty in removal. Traditional adsorbents are often expensive or inefficient, driving the need for sustainable, eco-friendly alternatives. In response to this problem, this study explores the use of Eucheuma cottonii, a fast-growing and widely available macroalgae, as a raw material for producing hydrochar through hydrothermal carbonization (HTC). The goal is to develop a renewable and effective adsorbent capable of selectively removing anionic dyes from contaminated water. Hydrochar was synthesized at two different HTC temperatures, 150°C and 250°C, and its surface properties were characterized using FT-IR and BET analyses. Adsorption experiments were conducted on four anionic dyes-Congo Red (CR), Direct Yellow (DY), Methyl Orange (MO), and Direct Green (DG)-under varying pH, contact time, dye concentration, and temperature conditions. The hydrochar produced at 250°C (HC-250) demonstrated the highest surface area and pore volume, leading to superior adsorption performance, particularly for DY. Kinetic studies revealed a chemisorption-driven mechanism, while thermodynamic analysis confirmed the adsorption process to be spontaneous and endothermic, with both chemisorption and physisorption contributing to dye removal. The adsorption behavior followed the Langmuir isotherm model, indicating monolayer adsorption, with minimal interaction between adsorbed molecules. Regeneration tests confirmed that Eucheuma cottonii hydrochar could be reused over multiple cycles with minimal efficiency loss. Future work could optimize the HTC process by adjusting pressure, heating rates, and pre-treatment methods to improve adsorption properties. Incorporating nanomaterials or metal oxides could enhance adsorption for a wider range of pollutants, while machine learning could predict adsorption behavior under different conditions. Additionally, exploring the hydrochar’s use in energy storage or as a catalyst offers promising applications. Life-cycle assessments (LCAs) and techno-economic analyses (TEAs) will be vital for assessing scalability and environmental impact, positioning Eucheuma cottonii hydrochar as a sustainable, multifunctional material for industrial applications.

Abstract

This paper examines waste management’s impact on environmental sustainability in Afghanistan against the backdrop of global waste management challenges. Globally, unsustainable waste management practices contribute significantly to environmental degradation, with 1.3 billion tons of food wasted annually-one-third of global production exacerbating hunger for one in seven people. Global waste production has reached 2.01 billion tons annually, with construction contributing 35%. Packaging and paper waste account for 40-65% of waste treatment costs in Europe, and tourism adds 35 million tons of solid waste annually. Plastic waste production has risen to 300 million tons per year, threatening marine life with projections of sea pollution surpassing fish populations by 2050. In Afghanistan, financial and technical constraints lead to significant food loss and improper waste disposal, creating unsanitary environments and health hazards. Household waste mismanagement ranges from 20% to 80%, with Kabul generating 3,300 tons of waste per day by 2025, 70% of which is organic. Data from 127 respondents reveal a positive correlation (0.265) between waste management and sustainability, accounting for 26.5% of the variation, with a 0.249 coefficient confirmed at the 1% significance level.
