Abstract

Energy transportation and distribution are crucial components in the national energy system, serving as the main link between energy sources and consumers. The efficiency of both systems is crucial to maintain the stability of energy supply and minimize energy loss during the distribution process. This study aims to explore the importance of energy transportation and distribution in the context of national energy security and the geographical and energy infrastructure challenges in Indonesia. Using a literature study method, this study collects and analyzes literature from various academic sources and relevant reports. The results show that an efficient energy transportation and distribution system plays a major role in reducing the energy gap between regions, expanding energy access to remote areas, and supporting sustainable economic development. In addition, Indonesia's geographical challenges as an archipelagic country, such as the distance between islands and population inequality, widen the energy infrastructure gap between the western and eastern regions. Investment in energy infrastructure development, especially in disadvantaged areas, and the integration of renewable energy are important steps in strengthening national energy security. This study concludes that in order to achieve better and more equitable energy security, inclusive and sustainable energy infrastructure development policies and strategies are needed.

Abstract

According to research published in the Journal of Applied Phycology, algae have the ability to produce biofuels with five times higher energy efficiency compared to soybean plants, making it a highly efficient and sustainable option for renewable fuels. The goal of this research is to use biotechnology to create biofuels from algae as a renewable energy. This study used a laboratory experimental design with a quantitative approach. Population: Microalgae or green algae that have high potential in lipid production, such as Chlorella vulgaris or Spirulina platensis, which are commonly used in biofuel research. Sample: Several species of algae were selected to test their effectiveness as biofuels, including genetically engineered species and natural species as a comparison. The results of the ANOVA analysis showed significant differences in lipid levels between treatment groups. The results of the T/Post-hoc test confirmed that the genetically engineered species had higher lipid levels, supporting the efficiency of biofuels. The regression results showed a strong positive correlation (R² = 0.68), which supports other studies that found that microalgae can produce biomass in a relatively short time with a controlled environment, making it efficient for large-scale biofuel production. The conversion efficiency of lipids to biofuels reached 85.5%, indicating that the transesterification method used in this study is very effective in converting algae lipids to biodiesel. The use of biotechnology in the production of biofuels from algae has great potential as an efficient and sustainable renewable energy source.

Abstract

The global transition toward low-carbon energy has positioned hydrogen (H₂) as a key renewable fuel, particularly for applications in fuel cells that require ultra-high purity. Ensuring hydrogen quality is essential to prevent catalyst poisoning and system degradation, as defined in ISO 14687:2019 standards. This study presents a simulation-based analysis of hydrogen purity using a Gas Chromatography–Mass Spectrometry (GC–MS) modeling approach to evaluate three production pathways: green hydrogen (from electrolysis), grey hydrogen (from steam methane reforming), and a fuel cell–grade feedstock.The simulation predicts impurity profiles such as O₂, N₂, CO, CO₂, CH₄, sulfur compounds, and water vapor, comparing each with ISO threshold limits. Results indicate that green hydrogen generally complies with ISO standards, while grey hydrogen exceeds CO₂ and sulfur limits. The fuel cell–grade sample shows near-complete conformity due to simulated purification processes such as pressure swing adsorption.These findings highlight that analytical modeling can effectively predict hydrogen quality and compliance potential across different production routes. The study emphasizes that advancing hydrogen technology requires not only cleaner production methods but also reliable analytical simulations to support quality assurance and sustainability in future hydrogen economies.

Abstract

Perovskite solar cells (PSCs) are a promising next-generation photovoltaic technology due to their high power conversion efficiency (PCE) and facile fabrication. However, structural instability, environmental sensitivity, and operational degradation limit their practical applications. This study investigates the effects of compositional and interfacial engineering on PSC performance and stability. Three perovskite types mixed-cation, interface-modified, and anti-perovskite were fabricated and characterized in terms of crystallinity, morphology, optical absorption, and electrical performance. Mixed-cation perovskites exhibited superior crystallinity, homogeneous morphology, broad optical absorption, the highest PCE (21.0 ± 0.3%), and 86.7% efficiency retention after 500 hours. Interface-modified PSCs enhanced Voc and fill factor, whereas anti-perovskites showed the lowest performance due to poor crystallinity and secondary phase formation. These findings indicate that combining cation/anion compositional engineering with interface modification is an effective strategy for developing high-performance and stable PSCs, offering insights for next-generation photovoltaic device optimization

Abstract

Solid-state batteries (SSBs) have gained strong attention for their higher safety, greater energy density, and improved electrochemical stability compared to liquid-electrolyte lithium-ion batteries, although challenges remain in optimizing ionic conductivity, interfacial resistance, and cycling stability. This study investigates the synthesis, structural characteristics, and electrochemical performance of the argyrodite solid electrolyte Li₆PS₅Cl (LPSC), produced via high-energy mechanical milling and integrated into a prototype SSB using a Li-metal anode and NMC811 cathode. XRD analysis confirmed the formation of the cubic argyrodite phase, while SEM revealed a homogeneous particle morphology conducive to efficient ion transport. Electrochemical impedance spectroscopy (EIS) showed an ionic conductivity of 1.87 × 10⁻³ S/cm at 25°C, which increased to 3.41 × 10⁻³ S/cm after annealing at 550°C. Galvanostatic cycling at 0.1C demonstrated stable capacity retention of 92.5% after 50 cycles, indicating strong interfacial contact between the LPSC electrolyte and NMC811 cathode. Comparative evaluation with recent SSB literature shows that the optimized LPSC electrolyte achieves performance levels comparable to state-of-the-art sulfide-based electrolytes due to improved crystallinity and reduced grain-boundary resistance. These results highlight the potential of mechanically milled LPSC as a promising solid electrolyte for next-generation SSB applications.
