The implementation of titanium dioxide (TiO2) as a photocatalyst material in hydrogen (H2) evolution reaction (HER) has embarked renewed interest in the past decade. Rapid electron-hole pairs recombination and wide band gap of a photo-sensitive material of TiO2 are detrimental toward the targeted catalytical reaction. In this study, we present the rational design, fabrication, photocatalytic performance of TiO2-Cu/CuO/Cu2O heterostructures (CuTi) using viable chemical reduction method. The Z-scheme and S-scheme are succesfully generated across the TiO2/CuO/Cu2O interfaces, while the Schottky junction arises on the Cu perimeters. This is evidenced from the blue shifted about 0.3 eV of Cu 2p core level determined by using X-ray photoemission spectroscopy (XPS), in combination with the formation of inverse V-shape of the Mott-Schottky plots. In addition, we find that Cu/CuO/Cu2O facilitates photon absorption range up to the visible region. The multiple heterojunction and the large number of OHsurface enhanced charge carrier transfer are associated to the suppression of photoluminescence (PL) intensity, high surface hydroxyl (OHsurface) density in CuTi probed by XPS, and fast electron transfer based on the electrochemical measurements. The presence of OHsurface inhibits the recombination of electron. A significant H2 photogeneration rate enhancement is achieved when an optimized 5 wt% Cu/CuO/Cu2O concentration is used on TiO2 to achieve 7,157.19 μmol·g−1 (1,789.30 μmol·g−1·h−1). Based on this finding, zero emission energy innitiative could be materialized under multiple heterojunctions in photocatalytic process is beneficial for enhancing the H2 production. © 2025 The Authors

Surface-enhanced Raman spectroscopy (SERS) has been widely utilized for the detection of disease biomarkers, pesticides, and environmental pollutants due to its exceptional sensitivity, real-time responsiveness, and unique interactions between adsorbates and substrates. Here, we present a composite metal/semiconductor material comprising TiO₂ nanosphere substrates integrated with in-situ-grown Au or Ag nanoparticles (NMNPs@TiO₂). These composite nanospheres are assembled by an electrophoretic self-assembly process to form a photonic crystal structure with three-dimensionally ordered periodic geometric features and show remarkable sensitivity and stability for SERS detection, achieving a detection limit as low as 10^-9 M for Rhodamine 6G. Beyond merely enhancing SERS signals by generating uniformly distributed metal plasmonic “hot spots” on TiO₂ substrates, similar to traditional semiconductor substrates, this photonic crystal substrate also exhibits advanced light absorption and localization capabilities. The absorbed light drives the defect excitation of TiO₂, facilitated by its multicrystalline structure. Excited electrons from the TiO₂ nanospheres contribute to the enhancement of localized surface plasmon resonance through charge transfer to noble-metal nanoparticles. Additionally, the synthesis of NMNPs@TiO₂ nanospheres avoids the use of toxic reagents, and substrate assembly is achieved through a simple electrodeposition process. This approach simplifies fabrication while enabling the production of SERS detectors with exceptional spatial and temporal signal stability. With increasing demands for higher detection sensitivity, signal uniformity, and detector durability for SERS detection applications, the NMNPs@TiO₂ nanosphere-based photonic crystal substrate underscores its potential to significantly improve the SERS detection efficiency, making it ideal for ultrasensitive che

Indonesia's geographical condition, which consists of 70 percent ocean territory, holds the potential for utilizing offshore wind turbines to provide cleaner energy. In this study, economic calculations were conducted for offshore wind turbines to generate green electricity and green hydrogen. The chosen ocean area for this endeavor is around the Papa offshore platform in the Java Sea. This area has experienced an economic decline, making it viable for repurposing as a sub-station for a powerhouse and an electrolyzer plant. Based on meteorological data analysis results, the area around the Papa offshore platform exhibits an average at height of 119 m;the wind speed is 5.5 m/*** prevailing wind direction is East Southeast (ESE), with a frequency of 25.2%. Further analysis of wind farms aimed at generating a capacity of 100.8 MW revealed an optimal potential energy generation of approximately 141,656.9 MWh per year. For scenario 1 (electricity production), the cost is $0.192/kWh. The levelized cost of hydrogen (LCOH) for scenario 2 (offshore electrolyzer) and scenario 3 (onshore electrolyzer) is $9.44/kg and $10.1/kg, respectively. To assess investment feasibility, a Net Present Value (NPV) analysis was conducted. This analysis yielded a selling price of electricity at $0.0271/kWh for the first scenario. For the second scenario, the selling price of hydrogen was calculated at $17.11/kg, and for the third scenario, it was $16.99/kg. Considering its flexibility and potential response to restrictions, the third scenario was deemed the most suitable for offshore utilization to produce clean energy. © Published under licence by IOP Publishing Ltd.

In the Fiscal Year 1996 National Defense Authorization Act, Congress amended the Clean Water Act to provide the Department of Defense and the Environmental Protection Agency authority to jointly establish standards for incidental discharges from Armed Forces' vessels. The uniform national standards would apply to discharges from vessels of the Navy, Military Sealift Command, Army, Marine Corps, Air Force, and Coast Guard to the navigable waters and contiguous zone of the U.S. and its territories. Uniform National Discharge Standards (UNDS) will require control of discharges, by either a technology or management practice. UNDS will facilitate the Armed Forces' ability to better design and build future vessels to be environmentally sound and to maintain the operational flexibility of Armed Forces' vessels both domestically and internationally. The development of standards for Armed Forces' vessel discharges may have greater impact on naval engineering requirements for future vessels than any other single environmental issue, These standards are expected to stimulate the development of innovative vessel pollution control technologies, which on be used for both Armed Forces' vessels and commercial shipping vessels. This paper provides an overview of UNDS development, summarizes the results of UNDS Phase I, provides a summary overview of the preliminary approach for accomplishing UNDS Phase Il, and discusses implications for future naval engineering efforts.

The reality in modelling the power system transition of an archipelagic country lies in the substantial investment required for interisland transmission lines and the uneven distribution of electricity demand. Approximately 72–75% of Indonesia's electricity demand is centered on Java, where the substantial population density constrains the land availability for renewable energy. Therefore, the spatial aspect in modelling Indonesian power system becomes important. This study assessed the differences in the decarbonisation of the Indonesian power system using single- and multi-region optimisation models and compared the isolated and interconnected power systems using the Integrated MARKAL–EFOM System (TIMES) Indonesia. The findings indicated that the isolated multi-region approach exhibited lower penetration of renewable energy compared to the single-region approach. Introducing interconnected power system enhanced the renewable energy mix by 2.5 times, reduced the overall system cost, CO2 storage capacity, and coal consumption by building 115 GW of interisland grid and importing 62% of electricity in Java from Sumatra, Kalimantan, and NT, which resulting in more distributed investment. However, due to the considerable distance, an interconnected power system is not considered a cost-effective solution for Papua, Sulawesi, and Maluku. Decarbonisation under coal phase-out plan helps reduce the interisland transmission system by 8.3%. © 2023, The Authors. All rights reserved.

The present study aims to investigate the effect of CaO and MgO as catalyst in pyrolysis of Indonesian sugarcane bagasse (SCB) for biofuel production. Prior to being used as raw material, SCB underwent acid washing to remove its inherent Ca and Mg content. Catalytic and non-catalytic pyrolysis experiment were performed in a fixed-bed reactor within a temperature range of 20-480 o C. Thermogravimetric Analysis was used to describe the mechanism of pyrolysis and one-step global model was employed to determine the reaction kinetics. Pyrolysis stage comprised of a rapid decomposition zone (260-340 o C) and slow decomposition zone (340-480 o C). TG curve confirmed that the endothermic cellulose decomposition and volatilization was more dominant than exothermic polymerization and aromatization of lignin. Moreover, CaO provided the highest reaction kinetics with the lowest reaction order compared with catalytic pyrolysis with MgO and non-catalytic process, both in rapid and slow zone. Differential Thermal Analysis (DTA) and Differential Thermal Gravimetric (DTG) corresponded to this by showing that the energy for decomposition in non-catalytic process and using MgO and without catalyst was higher than SCB0-Ca which gave the highest conversion rate. Hence, this study shows that the addition of CaO as catalyst can improve the kinetics of SCB pyrolysis.

Biofuel has been considered as an option to substitute petroleum fuels and reduce dependence of fossil fuel importation and greenhouse gasess emissions. Current Indonesia's biofuel blending mandates are cannot achieved due to technical, price and financial aspects. The objectives of the study are to obtain the optimum fuel supply mix by considering the fuel quality standard, production capacity and resource availability. Long-term fuel system optimization by minimum total system cost up to 2050 is carried out using TIMES-VEDA. The results showed that if goverment does not upgrade the quality of diesel up to EURO 4 and adapted EURO fuel specification with adjustment, the optimal fuel supply mix are FAME 50%-Diesel 50% in 2020-2030 and mix of FAME 47%-HVOSMR 53% in 2035-2050. For adapted EURO specification with adjustment except the sulphur content has fuel supply mix of HVOSMR 30%-Diesel 70% in 2020, FAME 20%-Diesel 80% for 2025-2030 and FAME 47%-HVOSMR 53% for 2035-2050. For gasoline, the optimum supply mix is Ethanol 5%-Gasoline 95% in 2020 and Ethanol-Ethanol2G 20%-Gasoline 80% in the 2025-2050. The utilization of biofuels can reduce the diesel and gasoline consumption for about 67-79% and 19% and reduce carbon intensity by 65-78% and 27%, respectively.

There is a great deal of emphasis currently in the Navy on the issues of reliability and maintainability. If a system or component is out of commission, it obviously cannot perform its mission. Thus, systems and components must be reliable, with low failure rates, and maintainable, with short repair times when the system does become inoperable. To be effective, these attributes must be incorporated into new ship systems early in the design stage. The Rankine cycle energy recovery (RACER) system is a heat recovery steam cycle designed to recover energy from the exhaust of an LM2500 gas turbine for augmentation of a ship's propulsion system. The RACER system provides several advantages to a gas turbine powered ship, one of which is improved fuel efficiency for significant annual fuel savings. This saving does not come free, however, since, in general, any additional system installed in the ship will have some maintenance requirements. In keeping with the Navy's current emphasis, a key philosophy in the design of the RACER system has been to minimize this maintenance burden. After a brief description of the RACER system and its design philosophy, the techniques being used during the design phase to minimize the maintenance burden on the fleet are presented. Trade-off studies concerning acquisition versus life-cycle costs, including fuel and maintenance costs, are discussed. Innovations incorporated into this state-of-the-art system are reviewed with an emphasis on design for affordability.
