Abstract

Background: A pier is an essential infrastructure in maritime transportation and inter-island connectivity. However, conventional piers are often less flexible, environmentally harmful, costly, and require regular maintenance, making them inefficient for remote islands. As an alternative, HDPE floating docks offer advantages in cost, installation speed, durability, and ease of maintenance. Southeast Sulawesi has around 651 islands, 86 of which are inhabited and have great potential in the fisheries and tourism sectors. Unfortunately, many piers in this region are unusable due to budget limitations and difficult construction access. HDPE floating docks can serve as a solution and even be utilized as platforms for water sports and recreation, supporting tourism development. Despite their potential, the application of floating docks remains limited. This study aims to design a floating dock made of HDPE as an alternative pier for islands with limited access. Methods: The design approach is based on technical analysis of local water conditions, including bathymetry, wave characteristics, and vessel activity loads. Findings: The HDPE structure has proven to be superior to concrete piers, mainly due to its modular and flexible form that allows for easy expansion. This makes HDPE floating docks an effective and practical solution for improving accessibility in remote island regions. Conclusion: This study finds that HDPE floating docks are a cost-effective, durable, and adaptable solution for improving inter-island connectivity. The Liwungan Island case demonstrates their technical feasibility and positive impacts on fisheries and tourism. Aligned with Blue Economy and Smart City initiatives, HDPE floating docks offer a scalable and sustainable alternative for small island maritime infrastructure. Novelty/Originality of this article: This article presents a site-specific HDPE floating dock design tailored to the hydro-oceanographic conditions and accessibility constraints of remote islands, integrating technical feasibility with fisheries and tourism functions as a scalable alternative to conventional piers.

Abstract

Background: Energy demand continues to rise in line with global population and industrial growth. In Indonesia, approximately 87.3% of total energy supply is still generated from fossil-fuel-based power plants, leading to high CO₂ emissions and environmental degradation. Despite its abundant renewable resources, such as hydropower, solar, and wind, the national transition toward clean energy remains slow. This study aims to examine strategic pathways to accelerate renewable energy development and establish a renewable energy–based society in Indonesia. Methods: This research employs a quantitative approach using secondary data derived from previous studies and official national statistics to evaluate Indonesia’s greenhouse gas (GHG) emission profile and renewable energy potential. Analytical techniques include the driver pressure state impact response (DPSIR) framework to assess causal relationships between human activities and environmental impacts, complemented by logical framework analysis (LFA) to identify the root causes hindering the adoption of renewable energy technologies. Findings: The study reveals that Indonesia possesses sufficient renewable energy resources to substitute existing coal-fired power plants entirely through the optimization of hydropower, solar, and wind energy systems. However, the transition process is hindered by multiple challenges, including technical limitations, financial constraints, and inconsistent policy implementation. The findings also emphasize the importance of community awareness, sustainable urban planning, and electrification of transportation systems to support nationwide decarbonization efforts. Conclusion: The development of a renewable energy society integrating energy efficiency, environmental awareness, and policy reform constitutes a critical step toward achieving a sustainable and climate-resilient future for Indonesia. Novelty/Originality of this article: This study introduces a holistic framework for establishing a renewable energy society in Indonesia by combining the DPSIR and LFA analytical methods. The proposed framework not only identifies systemic barriers but also outlines practical and policy-based strategies to accelerate the national energy transition while maintaining social, economic, and environmental sustainability.

Abstract

Background: In 2024, the Meteorology, Climatology, and Geophysics Agency reported that the average global temperature had exceeded the threshold of 1.5°C compared to the pre-industrial era. The rate of global warming is caused by the greenhouse gas (GHG) effect, which is dominated by carbon dioxide. The increase in atmospheric temperature is caused by CO2 from carbon emissions from the use of fossil energy sources, land conversion, and deforestation. This study examines technologies that can be used to optimize air quality and the types of renewable energy that can be integrated into air quality optimization technology designs. Methods: The methodological approach chosen in this study is a Systematic Literature Review (SLR). Data searches were conducted on several websites using the keywords “global warming,” “CO2 levels in Indonesia,” and “power generation technology.” Findings: Based on these issues, AQUANOVA was developed as an innovative air purification technology that can absorb CO2 in the atmosphere and be integrated with OTEC, PRO, and air purifiers to reduce carbon emissions in the air. Conclusion: This study developed the AQUANOVA innovation as a technology that can reduce CO2 emissions based on ANFIS-Fuzzy Logic management as an effort to achieve SDG points 7 and 15 in producing affordable renewable energy and restoring ecosystems. Novelty/Originality of this article: The integration of two electricity-generating technologies and the ANFIS-Fuzzy Logic automation system has created an innovative automatic and energy-efficient air purifier technology.

Abstract

Background: Indonesia’s energy landscape currently pivots between two bifaceted issues: the stagnation of the national energy transition and the inefficiencies of decentralized waste management. Despite East Java producing 9.27 million tons of dry-milled rice (GKG) in 2024, the resulting 1.85 Mt of rice husk remains an underutilized bio-resource. This wasted potential coincides with a sluggish renewable energy trajectory, where the 15.25% share by mid-2025 significantly trails the 23% national target. Methods: A data-driven framework integrating feedstock characterization, experimental data, and literature benchmarks was applied to evaluate catalytic fast pyrolysis and upgrading pathways for rice husk. Machine-learning-assisted correlation analysis and multi-objective optimization (NSGA-II) were used to benchmark key process variables, product yields, and fuel quality trade-offs. Findings: The technical foundation, built on detailed feedstock characterization, reveals that the CFP process yields ~46.9 wt% bio-oil, which is further refined to a 32.2 wt% biodiesel-equivalent yield. To enhance operational precision, various ML algorithms were evaluated; the Extra Trees model coupled with Non-dominated Sorting Genetic Algorithm II (NSGA-II) demonstrated superior predictive performance with an R2 of up to 0.96 and an RMSE <1 MJ/kg for calorific value prediction, showing strong accuracy for O/C ratio and CO2 fraction estimation. Techno-economic assessment confirms the framework's viability for pilot-scale implementation, projecting a positive NPV of IDR 50.4 million, an IRR of 23.78%, and a 2.93-year payback period. While sensitivity analysis highlights exchange rate volatility as a key financial risk, the model successfully positions farmers as active stakeholders in the value chain. Conclusion: The integrated CFP–ML framework demonstrates technical and economic viability for decentralized rice husk valorization, positioning farmers as active stakeholders in the renewable energy value chain and offering a scalable, bottom-up solution to support Indonesia’s energy transition in agricultural regions. Novelty/Originality of this article: By synthesizing mechanistic process design with data-driven decision support, this study provides a scalable, bottom-up pathway for decentralized waste-to-energy systems in agricultural regions.

Abstract

Background: Indonesia's industrial sector contributes 36% to national carbon emissions with 30-60% of thermal energy wasted as residual heat, while 68.5 million tons of waste per year, 60-70% of which is inorganic waste, is not managed optimally. Methods: This study used a literature review method with a systematic approach to examine and analyze the circular energy integration system. The literature sources used included Scopus and Web of Science indexed international journals, accredited national journals, reference books, and policy and regulatory documents related to waste and energy management in Indonesia. Findings: This system combines three main components, namely the production of RDF pellets from inorganic waste, the recovery of residual heat from industrial processes, and a real-time emission monitoring system to ensure environmental compliance. The integration of these three components creates synergies that not only reduce waste volume and greenhouse gas emissions but also produce alternative energy that can substitute fossil fuels in industrial applications. Conclusion: This study suggests that system integration can assist in implementing industrial decarbonization. Novelty/Originality of this article: The innovative aspect presented is the integration of RDF Pellets as co-firing with the utilization of residual heat in boilers so that it can be fully utilized.
