Abstract

Background: Indonesia accounts for 42% of global palm oil production, generating 60 million tons of biomass waste per year, mainly empty fruit bunches and palm kernel shells that have strong potential to be converted into hydrogen (H2) through biomass gasification as a renewable energy transition. This is relevant given that national hydrogen demand is projected to reach 6,282 TWh by 2060. Integrated chemical looping gasification technology with steam reforming using oxygen carrier NiFe2O4 shows promise for green hydrogen production from palm oil waste. Methods: This study was conducted through a literature review for comprehensive analysis and simulation data fulfillment. Process simulations were performed and analyzed using Aspen Plus, and sensitivity analysis was conducted for process optimization. Findings: Simulation results hydrogen production reaching 82.77 kg/hour at a gasification temperature of 700℃ and a steam-to-biomass ratio of 0.9 with H2 selectivity reaching 54.43%. Assessment of raw material quality and H2 production quality revealed a material utilization rate of 12.08 tons per ton of H2 produced. This simulation confirms the importance of optimizing the gasification temperature and steam-to-biomass ratio to produce high-quality syngas. PESTEL analysis shows that the use of palm oil waste for hydrogen has high economic value and creates a positive social impact. From a legal and environmental perspective, this conversion is in line with emission reduction regulations, making it feasible and highly implementable. Conclusion: Hydrogen production from palm oil waste using chemical looping gasification and steam reforming processes has significant potential for renewable energy in Indonesia. Novelty/Originality of this article: This study contributes by integrating technical, environmental, and socio-economic aspects in the analysis of hydrogen production from palm oil waste. Unlike most literature that focuses solely on process performance or technical aspects, this study combines Aspen Plus-based process simulation with PESTEL evaluation to assess the overall feasibility of the technology.

Abstract

Background: The increasing demand for sustainable and low-cost energy storage systems has encouraged the development of sodium-ion batteries as an alternative to lithium-ion batteries. However, the low electronic conductivity and slow Na⁺ diffusion kinetics of Na₂MnPO₄F remain major limitations for its cathode performance. Methods: In this study, Na₂MnPO₄F/C cathode materials were synthesized using a solid-state method with carbon coating derived from citric acid and coconut shell charcoal at concentrations of 0, 3, 5, and 7 wt.%. Findings: Structural characterization confirmed the successful formation of the Na₂MnPO₄F phase, where citric acid at 7 wt.% produced the highest phase purity (99.9%), while coconut shell charcoal achieved the highest purity at 3 wt.% (90.066%). SEM-EDX analysis revealed that increasing carbon concentration influenced particle morphology, elemental distribution, and surface porosity, while FTIR analysis confirmed the presence of Mn–O, PO₄, and C–C bonding within the composites. Electrochemical characterization using EIS demonstrated that carbon coating significantly improved charge-transfer behavior, with the 7 wt.% citric acid sample exhibiting the lowest resistance and the best electron transport capability. Conclusion: These findings indicate that carbon coating, particularly using citric acid, effectively enhances the structural stability and electrochemical performance of Na₂MnPO₄F cathodes, highlighting its potential for sustainable sodium-ion battery applications. Novelty/Originality oh this article: The use of carbon coating derived from citric acid and coconut shell charcoal at concentrations of 0, 3, 5, and 7 wt.% on Na₂MnPO₄F/C cathode materials successfully improved charge-transfer behavior, structural stability, and electron transport capability, particularly in the 7 wt.% citric acid sample which exhibited the lowest resistance and the best electron transport capability.

Abstract

Background: This study is situated in the context of increasing agricultural waste generation and the continued reliance on open burning practices in rural farming areas, which contribute to air pollution, greenhouse gas emissions, and occupational exposure risks. The aim of this study is to design and examine a transitional engineering solution in the form of an Internet of Things (IoT)-based Burner-Wet Scrubber system to support controlled biomass combustion and emission mitigation in agricultural waste processing. Previous studies have primarily focused on composting and agricultural waste reuse, with limited attention to practical solutions for small-scale farming. Methods: This study applies an engineering-experimental approach consisting of reverse engineering analysis, system design, prototype development, and pilot testing under controlled biomass combustion conditions. Data were collected through IoT sensor monitoring of combustion temperature and exhaust flow behavior, accompanied by observational assessment of particulate dispersion and functional performance of the wet scrubber unit. Findings: The proposed system is capable of processing 100 to 875 kg of agricultural waste per cycle while producing a char yield of 25 to 35% under controlled pyrolysis with an electrical power consumption of approximately 1200 W. The results show that the system operates effectively as an integrated combustion and filtration unit, characterized by more stable combustion conditions inside the burner chamber and a visible reduction in particulate dispersion compared to open burning conditions, while the monitoring interface facilitates transparent process observation and operational evaluation. These findings support the theoretical position of the system as an engineering intervention that aligns environmental mitigation objectives with practical field conditions. Conclusion: The study concludes that an IoT-based Burner-Wet Scrubber system has the potential to serve as a feasible, adaptive, and community-scale emission mitigation alternative for agricultural waste combustion. Novelty/Originality of this article: The novelty of this study lies in integrating a controlled burner, wet scrubber, and real-time IoT monitoring for smallholder agricultural applications.

Abstract

Background: The production of sustainable aviation fuel and bio gasoline from refined bleached degummed palm oil (RBDPO) has attracted increasing attention as a strategy to support low-carbon energy development. However, due to the complexity of the liquid product composition, determining the dominant reaction pathways and evaluating the technical and economic feasibility of the process remain challenging. This study aims to evaluate the techno-economic feasibility of hydrodeoxygenation of RBDPO under atmospheric to intermediate pressure conditions. Methods: The process technology was developed based on mass and energy balances and financial modelling. Atom mass balance combined with error minimization was applied to identify the dominant reaction pathways, Process simulations were performed using Aspen HYSYS, while laboratory data were used as the basis for economic evaluation. Equipment costs were estimated using Aspen Capital Cost Estimator to determine the total capital investment. Findings: The results indicate that several reactions occur during biofuel (bioavtur and bio gasoline) production, including hydrodeoxygenation, hydro decarboxylation, cracking, and polymerization. A standalone bioavtur plant requires a capital expenditure (CAPEX) of approximately USD 87,775,899 and an operating expenditure (OPEX) of USD 6,487,559, assuming an exchange rate IDR 15,500 per USD. The financial analysis yields an Internal Rate of Return (IRR) of 12.59% and a Net Present Value (NPV) of IDR 685,679,000,000. In comparison, a bio gasoline plant requires a lower CAPEX of USD 75,256,210 and an OPEX of USD 5,944,681 under the same exchange rate. Furthermore, it demonstrates better financial performance, with an IRR of 15.46% and a NPV of IDR 346,690,000,000. Conclusion: The results demonstrate that hydrodeoxygenation of RBDPO is technically feasible and economically viable under atmospheric to intermediate pressure conditions. These findings provide a practical basis for developing commercially competitive bioavtur and bio gasoline production systems. Novelty/Originality of this article: This study combines reaction pathways analysis and techno-economic evaluation of RBDPO hydrodeoxygenation for sustainable biofuel production.

Abstract

Background: Conventional mechanical locks are vulnerable to key duplication and manipulation, while existing IoT-based smart locks often lack multi-layer authentication, real-time monitoring, and energy efficiency considerations. Furthermore, energy efficiency considerations in smart lock systems have received limited attention despite their importance for sustainable engineering. These limitations necessitate the development of more robust security architectures that integrate biometric verification with cloud-based access management to enhance system reliability and scalability. Methods: This study implements a dual-layer smart lock system integrating fingerprint authentication (AS608 sensor) with cloud-based remote control via Blynk IoT platform. The system uses Arduino Mega 2560 for local control and Wemos D1 Mini (ESP8266) for cloud communication. Performance was evaluated based on authentication accuracy (FAR/FRR), power consumption, battery endurance, and notification reliability. Findings: The system achieved FAR = 0% and FRR = 2.5% over 40 attempts, with 100% cloud notification delivery under stable Wi-Fi. Power consumption measured 4.5 W (standby) and 15.6 W (active). Battery endurance reached 19.54 hours (standby) and 5.64 hours (continuous active). Total system cost was IDR 753,635, significantly lower than commercial alternatives. Conclusion: The developed prototype successfully integrates biometric authentication with cloud-based monitoring, resulting in a secure, scalable, and energy-efficient access control solution suitable for residential and commercial applications. This research contributes a reproducible engineering blueprint for dual-controller IoT lock systems with explicit energy performance characterization. The system exhibits enhanced reliability, accessibility, and operational efficiency. Novelty/Originality of this article: This research contributes a complete engineering blueprint for dual-layer IoT lock systems with explicit energy performance characterization, component-level power allocation, and cost analysis—features typically absent in existing smart lock literature.

Abstract

Background: The rising global carbon dioxide CO2 emissions necessitate efficient and sustainable carbon capture solutions, particularly for Indonesia’s industrial sector. This study explores the potential of Aceh serpentinite, a local mineral resource, as a raw material to produce magnesium oxide (MgO) for use as a reactive adsorbent in carbon capture, utilization, and storage (CCUS) technology. Unlike other methods that use expensive imported materials, this research utilizes domestic natural resources through an economical chemical and thermal activation process. Methods: The research methodology involved the preparation of serpentinite samples, which were thermally activated at 700 ℃ for 2 hours to remove hydroxyl groups and enhance mineral reactivity. This was followed by acid leaching using 1M hydrochloric acid (HCl) and precipitation with sodium hydroxide (NaOH) to extract the MgO. Findings: The findings demonstrated that thermal activation led to a mass loss of 9.63% (Loss on Ignition), indicating successful dehydroxylation of the mineral structure. Mass balance calculations estimate that approximately 3.54 grams of MgO could be produced from 13.19 grams of raw rock, representing a process efficiency of 72.8%. Conclusion: The findings confirm that Aceh serpentinite contains sufficient reactive magnesium to be a viable and cost-effective material for CCUS applications, offering a sustainable alternative for industrial emission reduction. Novelty/Originality of this article: The novelty of "REFINE" lies in the strategic use of common local minerals through a simplified and economical chemical path to replace expensive imported carbon capture materials, turning natural resources into high-value environmental products.

Abstract

Background: The palm oil industry faces increasing pressure to address its environmental impacts, particularly greenhouse gas (GHG) emissions from operational activities. This study conducts a comprehensive analysis of GHG emissions from palm oil operations using ISO 14064-1 standards at PT. X in Muaro Jambi, Indonesia. The research is particularly relevant given Indonesia's ENDC target of 31.89% unconditional emission reduction by 2030, to which the palm oil sector can contribute through methane capture and energy efficiency measures. Methods: The research employed a case study design with complete enumeration of emission sources, combining primary field measurements and secondary data. Emission calculations followed ISO 14064-1 integrated with IPCC 2006 guidelines, covering Scope 1, 2, and 3. Primary data included fertilizer usage (278.99 tons N/year), POME volume (113,667 m³/year), COD measurements (25,653.59 mg/L inlet), and fuel consumption (476,661 liters/year). MAC analysis was conducted using a 9.1% discount rate, with uncertainty qualitatively assessed. Findings: Total gross emissions reached 23,616 tCO₂e annually, dominated by Scope 1 (89.8%). POME fugitive emissions constitute the largest source (72.6%), followed by fertilizer (10.1%) and mobile combustion (6.9%). The POME system achieved 96.58% COD removal but generated 17,138.75 tCO₂e from methane. LULUCF sequestration (-48,866.69 tCO₂e) resulted in net emissions of -25,250.74 tCO₂e. MACC analysis identified three economically beneficial options with negative MAC: route optimization with biofuel (-125,210 Rp/tCO₂e), methane capture (-82,398 Rp/tCO₂e), and solar PV installation (-61,986 Rp/tCO₂e). These three options collectively achieve 88.9% of total abatement potential. Conclusion: This study provides the first ISO 14064-1 compliant GHG inventory for an Indonesian palm oil mill. However, the single-case design limits generalizability to other mills with different operational characteristics. Future research should include multi-site studies and quantitative uncertainty assessment. Findings support targeted emission reduction strategies and sector-specific policy development for climate mitigation.Novelty/Originality of this Study: This study integrates ISO 14064-1 GHG inventory with MACC analysis to identify cost-effective emission reduction strategies that support sustainable energy transition in the palm oil industry.
