Kata Kunci: Aerodinamika, Airship, Computational Fludia Design Abstract This research is motivated by the traffic congestion problem in Indonesia, specifically in Jakarta. According to data from the Central Statistics Agency (BPS), the population of Jakarta as of September 2021 is estimated to be 10.61 million people per year. This is an increase of 0.45% compared to the previous year, which had a population of 10.56 million. Road users in Jakarta are divided into four types of motor vehicles: passenger cars, buses, trucks, and motorcycles. According to data collected by the BPS, there are 21.7 million vehicles in Jakarta. Referring to previous research titled "The Potential of Using Airships to Support Development in an Efficient and Environmentally Friendly Manner" (Subagyo, 2011), the authors aim to explore the potential of using airships as a solution to mass transportation congestion. Currently, researchers are looking for solutions to the congestion in Jakarta. In this paper, the authors aim to contribute to finding the best solution to the current problem by providing input on the use of air accommodation using balloons. Specifically, the authors are using the Airlander 10 type balloon being developed in Hamburg. In order to achieve this goal, this research aims to conduct an analysis of the aerodynamics of the platform design using computational fluid dynamics. In order to achieve this goal, this research uses a quantitative method as a calculation of the aerodynamics of the airship combined with the Parent Design Approach method. This approach produces the characteristics of the airship currently in operation. Therefore, the authors would like to present this research to the city of Jakarta as an alternative solution to the traffic congestion problem itself.

Abstract

Abstrak Desain bus bertenaga listrik pada sistem transportasi sebuah kota dapat menjadi prospek mengganti bus berbahan bakar fosil konvensional dengan bus listrik yang didukung oleh energi matahari dan listrik yang disediakan oleh PLN. Untuk tujuan ini, kami mendesain dan menyelidiki lima wacana berbeda untuk memanfaatkan tenaga surya yang tersedia: (1) panel surya dipasang di atap halte bus, (2) panel surya dipasang di ruang terbuka yang tidak terpakai di ruang publik, dan (3) jalan surya, yaitu jalan yang dibangun dengan bahan fotovoltaik (PV). (4) Panel surya dipasang diatas danau, sungai ataupun laut. (5) Panel surya dipasang di atas bus. Analisis kelayakan awal menunjukkan bahwa lima skenario berkontribusi untuk memenuhi permintaan transportasi bus listrik, secara proporsional dengan ukurannya skenario (5) menyajikan biaya modal terendah dalam kaitannya dengan pembangkitan energi. Oleh karena itu, kami mengeksplorasi lebih lanjut skenario ini dengan melakukan simulasi operasi hariannya termasuk tindakannya dalam membeli dan menjual energi ke jaringan PLN, bila ada surplus energi. Secara keseluruhan, hasilnya menunjukkan bahwa, meskipun biaya modalnya tinggi, skema transportasi bertenaga surya menghadirkan alternatif yang layak untuk mengganti bus konvensional. Kata Kunci: Bus, Tenaga Surya, Analisis Kelayakan, Transportasi Alternatif Abstract The design of an electric-powered amphibious bus in a city's transportation system can be a prospect of replacing conventional fossil fuel buses with electric buses powered by solar energy and electricity provided by PLN. To this end, we designed and investigated five different discourses for utilizing available solar power: (1) solar panels installed on roofs of bus stops, (2) solar panels installed in unused open spaces in public spaces, and (3) roads solar, i.e., roads built with photovoltaic (PV) materials. (4) Solar panels are installed above lakes, rivers, or seas. (5) Solar panels installed on top of the bus. Preliminary feasibility analysis shows that the five scenarios contribute to meeting demand for electric bus transportation, in proportion to their size scenario (5) presents the lowest capital cost in relation to energy generation. Therefore, we explore this scenario further by simulating its daily operations including its actions in buying and selling energy to the PLN grid, when there is an energy surplus. Overall, the results show that, despite the high capital costs, solar-powered transport schemes present a viable alternative to conventional buses.

Abstract

The optimization of multilayer ceramic–polymer–natural fiber composite design has become a critical focus in the development of lightweight armor systems with high energy absorption efficiency and enhanced ballistic resistance. Recent studies have highlighted the synergy between ceramic front layers, polymer interlayers, and natural fiber backings that can effectively dissipate impact energy while maintaining optical transparency and structural integrity. This review consolidates 20 recent studies that analyze material selection, layer configuration, and hybridization methods for improving the mechanical and ballistic performance of composite systems. The results indicate that the integration of ceramic strike faces such as alumina (Al₂O₃) or boron carbide (B₄C), coupled with polymer matrices like epoxy or UHMWPE reinforced with natural fibers (kenaf, curaua, jute), yields an optimal balance between lightweight design, high energy absorption, and structural resilience. The review also discusses computational optimization approaches such as finite element modeling (FEM) and analytical hierarchy process (AHP) for predicting multilayer performance.

Abstract

Heavy metal contamination in water sources has become a growing environmental concern due to industrial, mining, and domestic waste activities. Metals such as Pb, Cd, Cr, Cu, and Fe are toxic, non-biodegradable, and tend to accumulate in living organisms. One effective method for removing heavy metals from water is adsorption, a process where metal ions adhere to the surface of solid materials. This method is favored for its efficiency, low cost, and ability to utilize natural materials. This literature review examines fifteen recent studies (2020–2025) focusing on the performance of natural and modified adsorbents derived from agricultural biomass, fishery waste, and natural minerals. The analysis emphasizes the influence of pH, contact time, and metal concentration on adsorption capacity and efficiency. The findings show that optimum conditions generally occur at pH 4–6 with contact times of 30–120 minutes, and higher metal concentrations increase adsorption capacity until surface saturation. Chitosan- and activated carbon-based materials achieved efficiencies exceeding 90%. The study highlights the potential of natural adsorbents as sustainable and eco-friendly materials for water treatment

Abstract

Molten Salt Reactors (MSRs) are among the most promising Generation IV nuclear reactor technologies due to their high thermal efficiency and inherent safety. However, their long-term operation is significantly challenged by the severe corrosiveness of molten fluoride salts, particularly FLiBe (Li₂BeF₄), which can degrade structural materials under high-temperature conditions. This study aims to compare the corrosion resistance of four candidate coating materials, namely High-Entropy Alloy (HEA), ODS NiMo–Y₂O₃, silicon carbide (SiC), and pyrolytic carbon (PyC), through a comparative literature review approach. The collected data were evaluated based on corrosion rate, surface morphology evolution, and the protective mechanisms developed at temperatures ranging from 650 to 750 °C. The analysis indicates that SiC and PyC exhibit the highest corrosion resistance, with nearly negligible corrosion rates owing to the formation of chemically inert passive layers. Meanwhile, ODS NiMo–Y₂O₃ demonstrates the best performance among metallic coatings due to the formation of a stable dual protective layer consisting of Cr₂O₃ and YOF. Although HEA provides relatively good corrosion resistance, its performance remains strongly dependent on the redox condition of the molten salt. Overall, the corrosion resistance ranking is determined as SiC ≈ PyC ODS NiMo–Y₂O₃ HEA Hastelloy-N. These findings provide a scientific basis for the development of hybrid coating materials with superior chemical stability and thermomechanical durability for structural applications in next-generation molten salt reactor systems.

Abstract

The development of Small Modular Reactor (SMR) technology demands innovative neutron absorber materials that are efficient, thermomechanically stable, and resistant to long-term irradiation. Boron carbide (B₄C) exhibits a high thermal neutron absorption cross-section, while hafnium (Hf) offers superior structural stability  and does not generate helium gas; however, studies integrating both materials remain limited. The main research gap lies in the lack of a comprehensive analysis comparing and combining the neutronic and thermomechanical characteristics of B–Hf materials for SMR control systems. This study aims to conduct a systematic literature review on neutron absorber materials based on boron, hafnium, and their composites to identify key parameters affecting neutron absorption efficiency, thermal stability, and irradiation resistance. Using the Systematic Literature Review (SLR) method applied to 15 Scopus-indexed journals from 2019–2024, the results indicate that Hf–B₄C composites provide an optimal balance between neutron absorption efficiency (≥90%), thermal conductivity (28–35 W·m⁻¹·K⁻¹), and structural stability up to 900 °C, making them a promising candidate for adaptive neutron control systems in next-generation SMRs.

Abstract

Sugapa District, Intan Jaya Regency, Papua, is a region prone to military conflict, with its highland, hilly topography and extreme climate. Temperatures can reach 9.2°C with high rainfall. These conditions demand robust, durable military equipment that provides maximum protection for Indonesian National Armed Forces (TNI) personnel engaged in military operations. One such area is Field Service Equipment (PDL) footwear. PDL footwear must meet the criteria for protection, high grip, abrasion resistance, and optimal insulation from temperature and water. However, the current standard TNI PDL footwear does not meet the criteria for the Sugapa theater of operations, Papua. This research was conducted to examine and characterize a Kevlar-based composite material with a polyurea coating as an innovative raw material for TNI PDL footwear. Kevlar is a material that has been proven to be superior anti-ballistic, with a very high tensile strength of approximately 3620 MPa and high resistance to impact and punctures. Furthermore, polyurea, an elastomer with a deformation elongation of 400-500%, is considered an appropriate material for enhancing the waterproof properties and chemical resistance of Kevlar. The research method used a systematic literature review to examine published research data on Kevlar, polyurea, military equipment, and the conditions in Sugapa District, Papua. Data analysis was conducted using a descriptive-qualitative method to address the urgent need for Kevlar-polyurea composite materials. The material analysis results showed that a Kevlar coating with a polyurea layer with a thickness variation of 0.2 mm on the front layer was the most optimal material configuration. This configuration provided the highest Ballistic Velocity Limit (Vbl) of 143.5 m/s, with a 58% increase in protection compared to plain Kevlar (90.8 m/s). Furthermore, the specific energy absorption efficiency also reached the highest value at 51.1 J.m2/g. The front-side coating has proven superior as a buffer layer, effectively absorbing impact energy and altering the fiber failure mode. In addition to the material used, the right outsole design is also crucial for slip control in the wet, muddy Sugapa operating terrain. The lightweight and flexible design demonstrates superior anti-slip performance. The combination of 0.2 mm Kevlar PU composite material with an optimal outsole design creates an effective surgical shoe in the Sugapa operating terrain.
