Abstract

Energy demand in Indonesia continues to rise in line with population and economic growth. Using Jakarta city of Indonesia, as a representative case, energy consumption in the transportation sector has risen significantly from year to year. This escalation contributes to deteriorating air quality and poses adverse impacts on public health. To prevent similar condition in the new capital city (Ibukota Nusantara - IKN), this study examines green hydrogen production to support Fuel Cell Electrical Vehicle (FCEV)-based transportation. The objective of this research is to evaluate the technical, economic feasibility and environmental benefit of a solar PV -power-driven Proton Exchange Membrane Water Electrolyzer (PEMWE) system for large-scale hydrogen generation in IKN. A dynamic PEMWE model was developed and simulated using MATLAB/Simulink/Simscape under operating temperatures of 60 °C, 80 °C and 100 °C at a current density of 1.2 A/cm2. Key performance indicators evaluated include membrane water diffusion flux, electro-osmotic drag, hydrogen production rate and system efficiency.  Result show that operation 80 °C achieves the optimal performance. Scaled-up calculations indicate a hydrogen output of 3,006.62 kg/day with an electricity demand of 143,617 kWh, resulting in specific energy consumption of 47.9 kWh/kg outperforming the commercial PEMWE range 51-55 kWh/kg. This production capacity can fuel approximately 1,500 FCEVs corresponding to a potential CO2 emission reduction of 13,112.7 kg CO2-eq/day. Economic analysis using the Levelized Cost of Hydrogen (LCOH), with a 6% WACC and 20-years project life, yields an annualized CAPEX of roughly MUSD 31 and electricity dominated OPEX of KUSD 577 per year. The resulting LCOH od USD 3.0/kg H2 aligns with projected 2030 green hydrogen cost target. In conclusion, Solar PV -powered PEMWE development in IKN is demonstrates holistic feasibility in term of technical viable, economically competitive and environment impactful.

Abstract

The oil palm plantation industry continues to expand rapidly, positioning Indonesia as the world’s largest producer, followed by Malaysia and Thailand. However, this growth is accompanied by a rising prevalence of musculoskeletal disorders (MSDs) among oil palm farmers, primarily due to heavy physical workloads and non-ergonomic postures during harvesting activities. A systematic search was conducted using PubMed, ScienceDirect, ResearchGate, and Google Scholar to identify studies published between 2020 and 2025 that examined MSD complaints, ergonomic risk factors, and work postures among oil palm workers. Nine articles met the inclusion criteria and were analyzed. The findings show that the most common MSD complaints occur in the neck, shoulders, wrists, lower back, feet, and knees. These issues arise mainly from manual harvesting tasks, such as cutting fronds and fresh fruit bunches (FFB) using egrek and dodos tools, as well as transporting harvested fruit. Key risk factors include awkward postures, repetitive movements, long working hours, heavy physical loads, age, and years of service. Beyond individual ergonomic factors, the studies reviewed highlight the significant impact of environmental conditions uneven terrain, slippery soil, extreme heat, dense vegetation, and varying land contours which increase biomechanical stress and force workers into compensatory postures, elevating MSDs risk. The interaction between tool design and challenging field conditions underscores that ergonomics and environmental management are closely interconnected. Recent advances in wearable technologies, including Electromyography (EMG) and Inertial Measurement Units (IMU), offer more accurate real-time assessments of posture, muscle activity, and environmental influences, supporting data-driven prevention strategies. While mechanical harvesting tools show potential to reduce MSD risk, their success depends on ergonomic design, field adaptability, and worker acceptance. Recommendations include designing environment-sensitive ergonomic tools, improving field accessibility, providing training on safe techniques, and implementing early sensor-assisted health monitoring.

Abstract

Water is an important element in human survival, ironically the benefits of water are often not seen by people who have access to very abundant water. Factor ecology is a determinant of water availability in an area, as is the case in the village of Geneng, Bulukerto, Wonogiri, Central Java. The preservation of the forest, which was initiated by a figure named Mbah Sadiman around the village, who planted Ficus Benjamina, is allegedly a factor in the availability of water in the village is very abundant compared to a few decades ago after forest fires that cause water shortages during the dry season. Forest spring water sources are able to produce an average discharge of 71.78 liters/s. The discharge can generate electrical energy with a Micro-hydro Power Plant of 4.5668 kW, which can generate a cash flow of IDR 57.7 million/year. The Net Present Value (NPV) obtained is IDR 224 million with a project life of 20 years. The economic value generated by forest environmental services in the form of water resources has significant economic value, and this value is obtained only from the use of electrical energy.

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

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

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.
