Abstract

The increasing presence of heavy metals (dense metallic elements, such as iron, which can be toxic at high levels) in industrial wastewater poses a substantial threat to environmental and human health, requiring the development of effective, sustainable treatment solutions. This study analyzes the potential of Pistia stratiotes L. (also known as Kiambang, a floating aquatic plant) as a phytoremediation agent (an organism that removes pollutants from the environment) for extracting Iron (III) (the trivalent, oxidized form of iron) from synthetic wastewater (water with artificially added contaminants). The experiment was conducted in batch reactors (containers where reactions occur in set amounts) under controlled conditions, with modifications to the number of plants and contact length (the duration plants are exposed to contaminated water) to evaluate the effectiveness of iron removal. Iron concentrations were monitored spectrophotometrically (by measuring the amount of light absorbed by sample solutions) over time, and the phytoremediation kinetics (the rate and mechanism of pollutant removal) were investigated using zero, first, and second-order kinetic models (mathematical approaches to describe how quickly reactions occur). Results indicated that Pistia stratiotes L. was highly effective at reducing Fe (III) levels, achieving removal efficiencies exceeding 99% under optimal conditions-specifically with 10 plants and 5 days of contact time. Kinetic analysis indicated that the second-order model provided the best fit, suggesting a chemisorption-dominated process (removal primarily involves chemical bonding between the plant and iron ions). These findings emphasize the potential of Pistia stratiotes L. as a green and efficient solution for Fe (III) removal from wastewater and offer significant insight into optimizing phytoremediation system design for industrial applications.

Abstract

The rapid growth of industry in Indonesia has led to an increase in Hazardous and Toxic Waste (B3), including liquid waste with complex chemical characteristics that pose high environmental risks. Treatment facilities for B3 wastewater can generate significant impacts such as Global Warming Potential (GWP), Human Toxicity Potential (HTP), and Freshwater Aquatic Ecotoxicity Potential (FAETP). This study evaluates the implementation of treated water recycling using the Life Cycle Assessment (LCA) method with the CML-IA Baseline approach. The functional unit applied was 1 m3 of treated wastewater. Results show that under the baseline scenario, GWP reached 102.89 kg CO2 eq, HTP 62.92 kg 1,4 DB eq, and FAETP 10.11 kg 1,4-DB eq. Applying recycling scenarios of 30%; 50%; and 80% consistently reduced impacts across all categories. Each 10% increase in recycling volume reduced environmental burdens by approximately 10%. These findings highlight recycling as an effective and measurable strategy to reduce environmental impacts while supporting sustainable production and consumption principles.

Abstract

Laboratory waste represents a growing global concern due to its potential impacts on environmental quality, human health, and safety when improperly managed. At IPB University, laboratory activities generate up to 5 tons of wastewater per month, emphasizing the need for effective and sustainable waste management strategies. This study proposes a structured gap-to-roadmap framework for independent chemical waste management in testing and calibration laboratories. The framework integrates criteria-based gap analysis, a literature-derived waste minimization checklist, and phased implementation planning. Data were collected through semi-structured interviews and literature review and analyzed using a qualitative, criteria-based approach. The results indicate that the PPLH IPB Laboratory generates approximately 100–481 L of chemical waste annually. While several minimization practices have been implemented, key gaps remain in standard operating procedures, labeling systems, temporary storage, and recovery and recycling practices. The checklist analysis further identifies feasible strategies, including solvent recycling and inter-laboratory chemical exchange, with significant potential for waste reduction and improved resource efficiency. The proposed framework translates identified gaps into targeted actions and assigns them into short-, medium-, and long-term implementation phases. This approach provides a practical and replicable tool for laboratories seeking to transition toward independent, compliant, and environmentally sustainable waste management systems, particularly in resource-constrained settings.

Abstract

This study conducts a cross-case analysis of compost-related technical cooperation projects implemented by the Japan International Cooperation Agency (JICA) in Southeast Asia, applying the six OECD/DAC evaluation criteria (relevance, coherence, effectiveness, efficiency, impact, and sustainability). The analysis covers six projects in Indonesia, Malaysia, Thailand, and Vietnam. First, publicly available ex-post evaluation reports were analysed through close reading of report narratives and cited evidence. Second, semi-structured interviews with stakeholders were used to triangulate documentary evidence and validate interpretations of the evaluation results. The findings suggest that project performance and sustainabilityare driven less by the technical sophistication of composting systems per se than by institutional fit and the design of local participation. As a comparative reference, the study also examines three cases under the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ)’s ProSoil programme. The comparison indicates that GIZ’s strategic combination of standardised ‘ready-made’ equipment and a long-term programme framework contributed to higher scores on efficiency and sustainability, whereas selected JICA projects demonstrated relative strengths in contextual adaptation and communityengagement. Overall, the results imply that effective compost technology cooperation requires project designs that explicitly integrate institutional conditions and an appropriate support horizon, in addition to technical content.

Abstract

Soil contamination by zinc (Zn) derived from landfill leachate poses significant ecological risks, particularly in regions with limited waste management capacity such as Indonesia. The Jatibarang landfill in Semarang has reported soil Zn concentrations exceeding the Ecological Soil Screening Level, highlighting the need for sustainable remediation strategies. This studyevaluated the stability of vetiver (Chrysopogon zizanioides)-based phytoremediation under varying plant densities and compost amendment in leachate-contaminated soil. A two-month greenhouse experiment was conducted using a 2 × 2 factorial completely randomised design with two planting densities (one and three plants per polybag) and two compost treatments (with and without compost). Parameters observed included soil Zn concentration, removal efficiency, bioconcentration factor (BCF), translocation factor (TF), plant biomass, and soil pH, analysed using two-way ANOVA (? = 0.05). All treatments significantly reduced soil Zn concentrations from 174.41 mg/kg to 49.33-52.17 mg/kg, corresponding to removal efficiencies of 70.09-71.72%, with no statistically significant differences among treatment combinations. Zinc accumulation occurred predominantly in the roots, reflected by higher root BCF values and TF values generally below one, confirming phytostabilisation as the dominant remediation mechanism. These findings indicate that vetiver-based phytoremediation provides a stable and reliable strategy for controlling Zn mobility in landfill leachate-contaminated soils, supporting its application as a sustainable soil management approach.

Abstract

Groundwater is a vital water source for many communities, especially in rural areas, but its quality often fails to meet clean water standards due to contaminants such as heavy metals, organic compounds, and unsuitable pH, TDS, and EC levels. This study examines an integrated water treatment system combining adsorption and ultrafiltration technologies. The process begins with adsorption using zeolite and coral ginger stone to remove contaminants through ion exchange and Van der Waals interactions. The pre-treated water is then filtered through an ultrafiltration membrane to eliminate suspended solids and microorganisms based on pore size exclusion. The novelty of this study lies in the variation of adsorbent compositions, namely 100 g zeolite, 100 g coral ginger stone, and a 50:50 g mixture. Results indicate that the 50:50 combination provides the highest efficiency in improving groundwater quality. Under optimal conditions, TDS decreased to 38 ppm, EC to 76 µS/cm, temperature reached 29.8 °C, and pH approached neutral at 6.28, meeting clean water standards.

Abstract

This study evaluates the sustainability of a communal wastewater treatment plant (CWWTP) in Pohjentrek Village, Pasuruan City, Indonesia, by integrating across five dimensions, technical, social, economic, environmental, and institutional using Multi-Dimensional Scaling (MDS), complemented by leverage and Monte Carlo analyses to identify critical attributes and validate model robustness. The results show that the social and environmental dimensions achieved a very sustainable status, with index values of 82.71 and 82.40, respectively. These findings reflect strong community acceptance of the communal wastewater treatment system and recognition of its environmental benefits, particularly in reducing potential groundwater contamination in densely populated residential areas. In contrast, the technical (67.38), economic (74.02), and institutional (72.10) dimensions were classified as sufficiently sustainable, indicating that the system remains operational but exhibits several structural vulnerabilities. Technical sustainability is constrained by effluent quality that has not yet consistently met regulatory standards and by the absence of routine effluent monitoring. While economic sustainability remains highly dependent on limited household contributions due to the absence of other funding source. Institutional sustainability largely relies on the commitment of local managers. The reliability of the sustainability assessment is supported by low stress values (0.14–0.15), high coefficients of determination (R² = 0.94–0.95), and Monte Carlo deviations below 5%, indicating a stable and statistically robust MDS configuration. Importantly, the sustainability classification reflects the aggregated performance across multiple dimensions rather than relying solely on individual indicators such as effluent compliance. This study contributes to the literature on sanitation sustainability by providing a validated, attribute-level sustainability diagnosis that integrates system performance with multidimensional analysis. The findings highlight the identification of sensitive attributes and priority interventions, enabling more targeted and effective management strategies for improving the sustainability of communal wastewater treatment systems.

Abstract

This study evaluated the reduction of chemical oxygen demand (COD) and total dissolved solids (TDS) in domestic wastewater using water jasmine (Echinodorus palaefolius) in a free water surface constructed wetland (FWS-CW) system. We characterized the influent wastewater, assessed the acclimatization of E. palaefolius to undiluted domestic wastewater, and quantified the effects of plant density and observation time on COD and TDS removal. The experimental campaign comprised wastewater sampling, reactor fabrication, plant acclimatization, batch treatment, and analyses of COD and TDS. Removal efficiencies were computed and the data analyzed by two-way ANOVA followed by Tukey’s HSD post-hoc test. The initial wastewater contained 275.88 mg/L COD and 286 ppm TDS. Echinodorus palaefolius adapted successfully to the wastewater and reached maximum removal efficiencies of 86.04% for COD and 12.41% for TDS in the 12-plant reactor on Day 12. The two-way ANOVA showed significant main effects of plant density and observation time on both parameters (p < 0.05), and Tukey’s HSD indicated that the presence of E. palaefolius significantly improved TDS removal compared with the unplanted control, although differences among the 4-, 8-, and 12-plant reactors were not statistically significant. These findings indicate that even moderate plant densities are effective for reducing COD and TDS in tropical domestic wastewater treated with FWS-CWs.

Abstract

The growth of Indonesia’s manufacturing industry has the potential to increase greenhouse gas (GHG) emissions. Therefore, this sector needs to become a key focus of emission control programs, aligned with the United Nations Sustainable Development Goals. The limited research comparing the contributions of manufacturing subsectors to national GHG emissions motivated this study. This research aims to (i) estimate projected GHG emissions from fuel consumption across medium- and large-scale manufacturing subsectors in Indonesia from 2025 to 2060 and (ii) determine the energy matrix with the lowest-emission scenario approaching the NZE-2060. GHG emissions are projected using LEAP software under four scenarios: business as usual (BAU), emission reduction (ER), clean transition 1 (CT-1), and clean transition 2 (CT-2). The projection results show that GHG emissions in 2060 will reach 593,520.08 Gg CO2eq (BAU), 320,734.36 Gg CO2eq (ER), 125,835.03 Gg CO2eq (CT-1), and 72,834.14 Gg CO2eq (CT-2). The CT-2 scenario produces the lowest emissions closest to the NZE-2060 target, while the ER scenario represents the most realistic pathway considering Indonesia’s renewable energy potential, but has to be complemented by other decarbonization efforts such as CCU/CCS technologies and biomass certification to achieve NZE-2060.

Abstract

This study aimed to evaluate the efficiency of microplastic removal using filtration media composed of coconut shell biochar and polyurethane sponge, as well as to assess the potential toxicity of the filtered water on feed consumption efficiency in Oreochromis niloticus and microplastic bioaccumulation by fish. The filtration system had a diameter of 10 cm, employed an upward flow configuration, and operated at a flow rate of 30 mL/min. Optimization was conducted using an artificial solution containing microplastics through two series-connected filtration columns with a media thickness of 40 cm. Toxicity tests on the filtered water were performed on Nile tilapia using feed efficiency and the fish’s bioaccumulation capacity of microplastics as parameters, with fish sized 4-5 cm. Results showed that the highest microplastic removal efficiency for the first and second filter averaged 79% and 93%, respectively. Toxicity tests based on feed efficiency showed favorable percentages in experiments using the effluent from the second series column filter compared to the first series, even though the fish feed efficiency of both water effluent decreased on day 14. The highest microplastic accumulation was observed in the digestive tract, followed by the fish gill and fish muscle, respectively. The bioaccumulation factor (BAF) value of microplastic in fish was less than 1, indicating a low level of bioaccumulation. This study demonstrates that the combination of coconut shell biochar and polyurethane sponge in two series of filtration has strong potential as an effective, economical, and accessible solution for microplastic filtration in water treatment.
