Laundry wastewater contains high organic matter and detergent residues that may degrade the receiving water quality if discharged without treatment. This study investigated the performance of coconut-shell activated carbon for reducing chemical oxygen demand (COD), biochemical oxygen demand (BOD), and detergent concentration in laundry wastewater, using batch and continuous fixed-bed adsorption systems. Four activation treatments were evaluated at the batch stage: no activation, NaOH 0.2 N, HCl 0.1 N, and sequential NaOH 0.2 N–HCl 0.1 N. The best activator was then applied in a continuous upflow column with adsorbent thicknesses of 15, 20, and 25 cm. HCl 0.1 N produced the highest batch removal efficiencies, reaching 73.30% for COD, 71.53% for BOD, and 75.73% for detergent. Adsorption equilibrium for all parameters was better described by the Freundlich model than by the Langmuir model, indicating adsorption on a heterogeneous carbon surface. In the continuous system, the 25 cm bed showed the highest concentration-based removal, reaching 97.12% for COD, 97.03% for BOD, and 99.66% for detergent, and provided the longest breakthrough delay. However, the 20 cm bed yielded the highest average pollutant-load reduction, indicating a more balanced operational performance. Hydraulic conductivity decreased from 0.000058 to 0.000036 m/s during operation, suggesting progressive pore blockage and adsorbent saturation. These results demonstrate that coconut-shell activated carbon has good potential as a simple and practical adsorbent for decentralized laundry wastewater treatment.

This study developed cellulose acetate-zeolite mixed matrix membrane adsorbers (CA-zeolite MMMAs) using cellulose acetate synthesized from OPEFB as the polymer matrix and natural mordenite zeolite as the adsorptive inorganic filler. The membranes were fabricated to enhance ammonia-nitrogen removal from synthetic ammonia solution and palm oil mill effluent (POME). Zeolite incorporation improved several membrane properties, including pure water flux, swelling degree, and porosity, compared with pristine cellulose acetate membranes. However, tensile strength and elongation decreased after zeolite addition, indicating a trade-off between adsorption-related properties and mechanical flexibility. The optimum adsorption performance was achieved using the CA-zeolite MMMA with 30% zeolite loading and a contact time of 70 min, producing an ammonia adsorption capacity of 1.051 mg/g under the selected operating conditions. Adsorption kinetic analysis showed that the pseudo-second-order model provided a better fit than the pseudo-first-order model, with an R² value of 0.9104. The adsorption equilibrium was better represented by the Langmuir isotherm model, with an R² value of 0.9247. The optimized membrane also showed regeneration potential, with first-cycle regeneration efficiencies of 83.37% using NaCl and 73.52% using HCl. When applied to actual POME, the membrane reduced ammonia concentration from 173.93 mg/L to 50.161 mg/L in batch adsorption and 52.136 mg/L in filtration, corresponding to removal efficiencies of 71.16% and 70.02%, respectively. Although the treated effluent remained above the regulatory discharge limit of 20 mg/L, the results demonstrate that OPEFB-derived CA-zeolite MMMAs have potential as pretreatment or polishing materials for ammonia-nitrogen removal from POME.

Post-disaster temporary shelters in Indonesia often generate significant construction waste because of their single-use nature. This study aims to map reusable and reconfigurable concepts as the foundation of Temporary Modular Shelter (TMS) material design and to analyse their contributions to environmental sustainability. A Systematic Literature Review (SLR) following the PRISMA 2020 protocol was conducted on peer-reviewed articles and indexed proceedings published between 2015 and 2025, retrieved from Scopus, ScienceDirect, and Google Scholar. Of 412 records initially identified, 87 peer-reviewed studies met the inclusion criteria. Thematic analysis was performed using NVivo 12 with a hybrid deductive–inductive coding approach. The findings show that reusable–reconfigurable principles are operationalised through modular systems and reversible dry connections that allow shelter components to be potentially reused or adapted for permanent housing construction. Five main material components were identified: frames, wall panels, roofs, flexible elements, and flooring/base modules. The approach is reported in the reviewed literature to support construction waste reduction, circular economy practices, lower embodied carbon, and improved resource efficiency, although the magnitude of these benefits varies with material type, transport distance, and the number of reuse cycles. This study contributes an integrative sustainability-based framework linking reusable–reconfigurable principles with post-disaster TMS material systems. Remaining challenges include module standardisation, local human resource capacity, comprehensive Life Cycle Cost analysis, and socio-economic integration. The framework provides a reference for policymakers, researchers, and practitioners developing adaptive and sustainable temporary housing in disaster-prone regions.

Flood inundation mapping is a critical tool for urban flood risk assessment in tropical cities. This study investigates flood inundation extent in Medan Maimun Sub-district, Medan City, one of the most flood-prone areas in North Sumatra, Indonesia, where flood depths of approximately 3 meters were reported in February 2022 and December 2023. The study aims to: (1) determine design rainfall through frequency analysis and calculate design flood discharge for return periods of 2, 5, 10, 25, 50, and 100 years using the Nakayasu Synthetic Unit Hydrograph (SUH Nakayasu) method; (2) simulate flood routing using two-dimensional hydraulic modeling; and (3) map the resulting flood inundation extent for each return period. Rainfall frequency analysis used annual maximum rainfall data from two stations for the period 2014–2023, with the Log Pearson III method selected based on Chi-Square goodness-of-fit testing. Design flood discharges ranged from 383.403 m³/s at the 2-year return period to 555.149 m³/s at the 100-year return period. Flood routing and inundation mapping were performed using HEC-RAS version 5.0.7 integrated with RAS Mapper. Total inundation area increased from 110.982 ha at the 2-year return period to 126.581 ha at the 100-year return period, covering approximately 41.6% of the sub-district area at the 100-year return period. The model was not formally calibrated or validated against observed flood data; results should be interpreted as indicative of relative flood risk patterns rather than precise predictions. The flood inundation maps produced provide a useful scientific basis for flood mitigation planning in Medan city, Indonesia.

The mining industry faces significant challenges in maintaining sustainable operations due to geological uncertainty, environmental degradation, and increasing demands for effective environmental management. Geological hazards such as slope instability, landslide potential, groundwater inflow, mine drainage problems, erosion, and waste rock instability may directly affect environmental quality and operational sustainability. This study examines the relationships among Geological Risk Assessment (GRA), Environmental Management Practices (EMP), and Sustainable Mining Operations (SMO) using survey responses from 150 mining professionals in Indonesia, covering coal, nickel, copper, and gold mines. A cross-sectional survey design and Structural Equation Modeling–Partial Least Squares (SEM-PLS) were applied to assess the associations among GRA, EMP, and SMO and to evaluate the mediating role of EMP. The results indicate that GRA is positively associated with EMP (β = 0.718) and SMO (β = 0.402), while EMP positively affects SMO (β = 0.424). EMP also partially mediates the relationship between GRA and SMO, with an indirect effect of β = 0.305. These findings suggest that geological risk assessment contributes to sustainable mining by strengthening environmental management practices, particularly in relation to mine water management, erosion control, land reclamation, waste management, and environmental impact monitoring. The study provides a conceptual SEM-PLS model linking geological risk, environmental management, and sustainable mining performance, offering practical insights for improving environmentally responsible mining operations in Indonesia.

Sekolah Alam Bogor (Bogor Nature School) provides a relevant case for examining school-based circular waste management in Indonesia. Although the school applies reduce, reuse, and recycle (3R) principles, their implementation remains suboptimal due to the absence of systematic flow mapping and quantitative evaluation. This study aims to quantify waste generation and composition, map material flows, and evaluate the Waste Diversion Rate (WDR) of the school’s circular waste management system. A mixed-method case study was applied, combining field observation, in-depth interviews, and direct weighing of waste over 14 effective school days across five source units: Pre-School, Elementary School, School Kitchen, Middle School, and School of Makers, The results show an average waste generation of 165.15 kg/day, dominated by organic waste (71.23%), with inorganic waste accounting for 28.77%. Salam Permaculture composts organic waste, recyclables are channeled to Bank Sampah Salam Aid, and residues are incinerated. The system achieved an internal Waste Diversion Rate (WDR) of 76% (77.79% when community-contributed recyclables from the Dropzone program are included), indicating substantial waste diversion. However, approximately 24% of the waste (39.70 kg/day) remains as residue treated through incineration, whose emissions and ash quality were not assessed and require further evaluation. These findings indicate that systematic flow mapping and data-driven evaluation are essential for strengthening source-based waste management in educational institutions.

Lake Sentani is the largest lake in Papua and serves as an important source of raw water, fisheries, and livelihoods for communities in Jayapura. Increasing anthropogenic pressures from settlements, agriculture, aquaculture, and tourism have raised concerns regarding the deterioration of its water quality. This study compared the water quality status of Lake Sentani using five assessment methods: Pollution Index (IP), STORET, CCME-WQI, BC-WQI, and NSF-WQI. Water samples were collected from five stations representing littoral, limnetic, and human-activity-influenced zones. The analyzed parameters included physical (temperature, TDS, TSS, turbidity, and Secchi depth), chemical (pH, dissolved oxygen, BOD₅, COD, nitrate, phosphate, ammonia, and sulfate), and biological (total coliform) indicators. The results indicated IP values ranging from 3.95 to 6.43 (lightly to moderately polluted), STORET scores from –20 to –44 (moderately to heavily polluted), CCME-WQI values from 47.3 to 71.2 (marginal to fair), BC-WQI values from 44.7 to 68.5, and NSF-WQI values from 46.1 to 70.3. Station S3 (Sentani Town) consistently exhibited the poorest water quality, whereas Station S4 (Ayapo) showed the best condition. Elevated BOD₅, phosphate, ammonia, and total coliform were identified as the principal parameters contributing to water quality degradation. The five assessment methods produced generally similar spatial patterns across the sampling stations, with Pearson correlation coefficients ranging from 0.89 to 0.97, although these correlations should be interpreted cautiously given the limited number of monitoring stations. Among the evaluated approaches, CCME-WQI provided a balanced assessment by integrating the scope, frequency, and magnitude of water quality exceedances, making it a suitable framework for routine monitoring of tropical lake ecosystems under the conditions examined in this study.

The building subsector is the largest contributor to greenhouse gas emissions in Indonesia’s energy sector, with approximately 90% of its emissions stemming from electricity consumption. The implementation of green building concepts is one of the efforts to improve energy efficiency and reduce these emissions. This study aims to evaluate the energy efficiency and conservation (EEC) score in the GREENSHIP rating system and compare it with energy savings estimates using the excellence in design for greater efficiencies (EDGE) Building App at the Rectorate Building of the University of 17 August 1945 in Surabaya. The study employed a quantitative descriptive method based on electricity consumption data and observations of electricity usage for the GREENSHIP evaluation, as well as calculations of the Window-to-Wall Ratio (WWR) and building characteristics for energy performance simulations using the EDGE Building App. The results show that the GREENSHIP EEC score reached only 7 out of a total of 36 points, while the EDGE simulation indicated a potential energy savings of 26.37%. These results indicate that EDGE focuses on the percentage of energy savings compared to a baseline building, whereas GREENSHIP evaluates the implementation of energy management, efficiency, and conservation strategies more comprehensively. Therefore, a high level of energy savings does not necessarily result in a high GREENSHIP score without the comprehensive application of energy efficiency criteria.
