Abstract

The impact of global climate change has changed the cropping pattern system and the quality of carrying capacity and environmental capacity in accordance with current dynamics. Increased sea temperatures and the El-Nino and La-Nina phenomena cause changes in environmental conditions that affect monthly rainfall, thus disrupting the pattern and production of agricultural products. This study was conducted to ensure that the policy on carrying capacity and environmental capacity becomes a reference in all development planning documents in Central Java Province. The research objectives are analyzing the benefits and urgency of carrying capacity and environmental capacity in Central Java. And provide policy recommendations to integrate the carrying capacity and capacity of the environment in order to improve the achievement of the target indicators of sustainable development goals from the environmental sector as a basis for formulating sustainable development scenarios. The result of the study concluded that Central Java Province has not optimally implemented the carrying capacity and capacity policy in development planning so the negative impact of development in the form of environmental damage is still a priority issue in achieving sustainable development goals.

Abstract

This study analyzes community participation and environmental quality in supporting sustainable water-based tourism management at Umbul Brintik, Klaten Regency, Indonesia. The research aims to assess the level of community participation across management stages, evaluate water quality as an indicator of environmental sustainability, and examine the integration between social participation and environmental governance in a community-managed tourism destination. An explanatory mixed-methods approach was employed, combining questionnaire surveys of local residents analyzed using a non-compensatory Community Participation Index (CPI), water quality assessment using the STORET method and the Water Quality Index (WQI), and in-depth interviews with key stakeholders. The findings indicate that community participation is generally high, with very high levels observed at the implementation, benefit-sharing, and evaluation stages, while participation at the planning stage remains comparatively lower. Water quality analysis shows that all physical, chemical, and biological parameters meet national standards, with STORET results indicating good water quality and WQI values classified as excellent. The integrated analysis reveals that although strong community participation coexists with favorable environmental conditions, environmental governance remains largely informal and lacks institutionalized mechanisms such as routine monitoring and formal environmental management procedures. This study demonstrates that high participation levels do not automatically ensure long-term environmental sustainability and highlights the need to strengthen participatory planning and institutionalize preventive environmental management to sustain community-managed water-based tourism destinations.

Abstract

Cilegon City is an industrial city with an area of 175.51 km2, approximately 43.6% of which is comprised of coastal and marine areas. Industrial activities, ports, and even household waste can produce pollutants that flow into the sea. One of the pollutants entering the waters is heavy metals. Common heavy metals found are Cadmium (Cd), Copper (Cu), and Lead (Pb). This research was conducted in February 2022 in the waters of Cilegon. Heavy metal concentration measurements were conducted at an ISO 17025:2017 accredited laboratory. One liter of seawater samples was from the surface (0-50 cm), filtered, and HNO3 preservative was added to a pH of 2 in polyethylene bottles. Measurements of aquatic environmental quality parameters, including temperature, salinity, and pH, were conducted in situ. Dissolved heavy metal concentrations were analyzed descriptively and compared with seawater quality standards in accordance with Government Regulation Number 22 of 2021 concerning the implementation of environmental protection and management. Water quality assessment was conducted by calculating the Pollution Index in accordance with the Decree of the Minister of Environment Number 115 of 2003. The results of the water temperature measurements ranged from 28.8 to 30.4°C, salinity ranged from 29 to 31 ppm, and the water pH obtained was 7.7 to 8.4, which stated that the environmental parameters of the waters met the quality standards. The concentration of dissolved Cd was <0.00003 at all stations. The concentration of dissolved Cu obtained ranged from <0.006 to 0.0129 mg/l; two stations obtained results exceeding the quality standards. The concentration of dissolved Pb obtained ranged from <0.00012 to 0.017 mg/l; two stations exceeded the quality standards. The results of the water pollution index calculations stated that all research stations were in a slightly polluted condition.

Abstract

Artisanal and Small-Scale Gold Mining (ASGM) activities in Ai Mual Village, Lantung Sub-district, Sumbawa Regency, have the potential to degrade environmental quality, as indicated by analysis results showing that cyanide concentrations and pH levels in water near the mining area exceed the water quality standards for Class I and II, as stipulated in Government Regulation No. 22 of 2021. The methodology employed includes spectral analysis based on vegetation indices (NDVI, ENDVI, GNDVI) and iron oxide indices, which serve as preliminary identification or anomaly visualization. These results are subsequently analyzed in more detail and validated using laboratory data on physical, chemical, and biological parameters. The results indicate that low NDVI values (≤ 0.1) and high Fe-oxide index values are distributed across active ASGM zones, suggesting substantial environmental stress on vegetation. Laboratory analysis revealed that several locations contained cyanide concentrations ranging from 0.02 to 0.06 mg/L, exceeding the quality standards set by Indonesian Government Regulation No. 22 of 2021. The low pH value (2.17) recorded at site SWL-2 indicates symptoms of acid mine drainage (AMD), which further enhances the mobility of heavy metals into aquatic systems. Biologically, SWL-1 recorded fecal coliform counts of 16,000 MPN/100 mL and total coliform at 160,000 MPN/100 mL up to 32 times the allowable limits. Conversely, SWL-2 showed low coliform levels, possibly due to acidic conditions that inhibit bacterial survival. The findings were visualized through thematic maps and spatial overlays, highlighting high-risk zones covering approximately ±65.33 hectares located in Ai Mual Village, Lantung Subdistrict .

Abstract

Oil and gas industrial activities have caused serious water pollution and adverse health effects on human, animals, plants, and aquatic organisms. Biofilms have significant potential for remediation of polluted water. This study aimed at evaluating the efficiency of bacterial biofilm in bioremediation of crude oil polluted mangrove forest water of Gbaramatu Kingdom of Warri South-West, Delta state, Nigeria. The total petroleum hydrocarbon (TPH) was determined by gravimetric while total hydrocarbon content (THC) and total oil and grease (TOG) were estimated using Fourier Transform Infrared (FTIR) spectroscopic technique. The screening of bacterial isolates for biofilm formation was conducted using microtitre plate assay and tube method. The crude oil degradation capacities of the bacterial isolates and bacterial biofilms were determined by gravimetric technique and GC-MS analysis. The mangrove water contains significant (p < 0.05) amount of THC (823.05 mg/L), TPH (1132.11 mg/L), and TOG (333.99 mg/L). The result showed that Pseudomonas isolates exhibited high significant (p < 0.05) growth intensity (80.94 %) compared to the Bacillus (75.04 %) and Micrococcus (53.20 %) isolates. The Pseudomonas (1.070 OD) and Micrococcus (0.818 OD) produced maximum significant (p < 0.05) amount of biofilm compared to the Bacillus (0.082 OD). The bacterial biofilms displayed more significant (p < 0.05) crude oil degradation efficiency compared to the mixed bacterial isolates. More number of peaks, each represents different petroleum components were observed in the untreated water sample. The water sample treated with the bacterial biofilm showed disappearance of these peaks with few peaks of low intensity. Total degradation of short-chain hydrocarbons and low molecular weight PAHs coupled with partial degradation of long-chain hydrocarbons and high molecular weight PAHs by the biofilm was observed. The bacterial biofilms are highly effective in degradation of crude oil components than the bacterial isolates indicating that the biofilms are significant agents for bioremediation of crude oil polluted environment.

Abstract

This study visualizes worldwide study patterns on human-elephant conflicts (HEC) and sustainable cultivation management across the last three decades using a thorough bibliometric assessment. The analysis, which uses VOSviewer to combine descriptive statistics, network visualization, and content-based clustering, is based on 342 Scopus-indexed documents published between 1995 and 2025. The results show a significant increase in research output following 2015, underscoring the growing interest in conserving biodiversity in plantation-driven landscapes within scientists and policymakers. Four main thematic clusters were found through co-citation and keyword analyses: policies supporting sustainable land management, community-based conservation and collaborative governance models, conflict mitigation and crop protection strategies, and ecological investigations on elephant behavior and habitat use. The findings point to a paradigm shift toward data-driven, interdisciplinary approaches that include climate adaptation tools, machine learning-based conflict prediction, and remote sensing. This research provides a fresh viewpoint and lays a solid basis for cooperative solutions combining ecological, technological, and socioeconomic aspects by connecting HEC studies with environmentally friendly plantation practices. To promote human-elephant coexistence while maintaining plantation output, future research should fill geographic understanding gaps, enhance cross-border collaborations, and broaden predictive analytics, especially in Southeast Asia.

Abstract

The annual electricity consumption at the Gunung Mergi Mining Office, which reaches ±55,000 kWh, incurs significant operational costs, necessitating a more efficient and sustainable energy supply alternative. To address this need, a technical simulation was conducted using Helioscope software to determine the appropriate rooftop solar power system configuration based on the roof conditions and solar radiation potential at the location. An economic analysis was performed using the Payback Period, Net Present Value (NPV), and Profitability Index (PI) methods to assess the feasibility of the investment. The simulation results show that a roof area of 474.41 m² can accommodate 54 solar modules with a capacity of 550 Wp, with an energy production of ap-proximately ±46,000 kWh per year or capable of meeting 84-85% of the office's electricity needs, and has the potential to save IDR 40-46 million per year. The financial analysis resulted in a positive NPV of IDR 20,076,884, an IRR of 1.078, and a Discounted Payback Period of 22.1 years, which is still within the technical lifespan of solar panels. From an environmental perspective, supplying most of the office’s electricity from rooftop solar can substantially reduce Scope 2 emissions associated with PLN electricity use, thereby lowering the carbon footprint of non-productive mining facilities. These findings indicate that the implementation of rooftop solar power plants is feasible and supports cost efficiency and the transition to clean energy in the mining sector.

Abstract

Global warming, largely driven by rising CO₂ levels, poses a serious environmental threat. Meanwhile, the decline of green spaces, especially in cities, reduces natural CO₂ absorption. In response to this issue, this true experimental research introduced an innovative approach called Smart Microalgae Reactor, which utilizes Spirulina Sp. as an alternative CO₂ absorber to produce oxygen. This study aimed to evaluate the effectiveness of microalgae Spirulina Sp. in capturing CO₂ through three experimental setups: Reactor 1 (2000 mL Spirulina Sp.+ 2 L/min CO₂), Reactor 2 (1500 mL + 2 L/min CO₂), and a Control (2000 mL, no CO₂). CO₂ was injected daily for 1 minute, and key parameters Dissolved Oxygen (DO), Optical Density (OD), and growth rate (μ) were measured over 13 days. The results showed Reactor 2 had the highest DO increase (12.6 mg/L, 63.64%) and fastest early growth (0.0904 day⁻¹), while Reactor 1 achieved the highest OD (1.550, 111.48%) but slower growth. The control performed weakest, confirming that added CO₂ boosts photosynthesis. The study proves that smart microalgae reactor is an effective, sustainable solution for urban CO₂ reduction, offering a viable alternative where traditional greenery is limited.

Abstract

High-ratio biomass co-firing has emerged as a practical pathway for reducing emissions from small coal-fired power plants in remote island grids. This study evaluates the environmental performance of palm kernel shell (PKS) co-firing at 50%, 75%, and 100% blending ratios in a stoker-fired boiler at PLTU Tidore, Indonesia. Direct stack measurements and fuel characterization were used to quantify the effects of PKS substitution on sulfur dioxide (SO₂), nitrogen oxides (NOx), particulate visibility, and ash characteristics, while also assessing the stabilizing role of a redundant baghouse filtration configuration. The strongly reduced sulfur and ash content of PKS, as detailed in the fuel analyses, led to substantial declines in SO₂ emissions. Concentrations decreased from 182.95 mg/Nm³ under coal-only operation to 16.53 mg/Nm³ during 100% PKS firing. NOx levels remained within an operationally stable range (303.87–452.14 mg/Nm³) despite non-linear fluctuations associated with fuel–temperature interactions. PKS firing also resulted in progressively lighter stack plumes and the production of finer, less clinker-forming ash. Throughout all tests, the redundant bag filter system maintained uninterrupted particulate control and prevented opacity excursions, ensuring the reliability of the environmental measurements. These results demonstrate that PKS co-firing, supported by robust filtration redundancy, provides a feasible and cost-effective approach for improving air quality performance in isolated coal-dominated grids. The findings highlight a replicable strategy for integrating biomass into small-scale thermal plants while maintaining emission stability and operational continuity.

Abstract

Indonesia’s commitment to achieve Net Zero Emissions (NZE) by 2060 requires substantial decarbonization of its electricity sector, including the phase-out of diesel-based isolated power systems in remote and underdeveloped regions (3T regions). While de-dieselization programs have been widely promoted as a technically and economically feasible solution, their environmental performance remains uneven. This study examines Indonesia’s de-dieselization program implemented by PT PLN (Persero) through the lens of Multi-Level Governance (MLG), focusing on how governance dynamics shape the realization of emission reduction benefits. Using a qualitative research design, this study integrates document analysis, in-depth interviews with national, corporate, regional, and community-level actors, and secondary data-based carbon emission estimation. The findings reveal persistent governance failures manifested as policy misalignment, overlapping mandates, and accountability gaps across governance levels. These failures delay project implementation, prolong diesel operations, and generate a systemic “environmental performance gap,” where planned emission reductions are not fully realized. Carbon estimation indicates that delayed or incomplete de-dieselization results in the loss of significant mitigation opportunities, amounting to hundreds of thousands of tons of CO₂ annually. The study contributes to the energy transition literature by conceptualizing emission reduction as a governance-dependent outcome rather than an automatic result of technology substitution. Policy implications emphasize the need to embed environmental performance indicators explicitly into governance frameworks and to strengthen cross-level accountability to ensure that de-dieselization delivers tangible climate benefits in isolated power systems.
