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

Missiles are strategic defense equipment that have a high deterrent effect in the national defense system because they have high destructive power, high precision, and can be launched remotely. With the above characteristics, the missile is a high-tech product, and it still needs a lot of engineering effort to master the technology, especially the propulsion / propulsion system technology which is mostly in the form of turbojet engines. With the above background, this study designs and analyzes one of the main components of the missile propulsion system, namely the compressor impeller. This study analyzes the pressure ratio and mass flow rate of compressor air whose values are used to obtain the impeller design of a small turbojet engine compressor on a surface-to-surface cruise missile propulsion system. The method used is analytical method. The conclusion of the study is that the combination of a compressor pressure ratio of 4 and an air mass flow rate of 2.5 kg/s can produce a target thrust of 1,300 N, and the diameter of the turbojet engine  is smaller than the maximum allowable space diameter of 270 mm.

Abstract

Aircraft engine maintenance strategies have evolved from schedule-based approaches toward condition-driven systems that emphasize actual component health conditions. The TPE331 turboprop engine used on the CASA 212-200 aircraft is critical in supporting both military and civil aviation operations. However, its maintenance process faces challenges related to high operational intensity, diverse operating environments, spare part availability, and turnaround time. This research was conducted at PT Nusantara Turbin dan Propulsi (NTP) to analyze the existing maintenance system and to propose the implementation of Condition-Based Maintenance Plus (CBM+) as an optimization strategy. The research employed a qualitative descriptive approach using maintenance records, engine performance parameters, and operational cost data. The results show that CBM+ implementation has the potential to reduce unexpected downtime, improve cost efficiency by approximately 8–12%, and enhance fleet readiness through early detection of component degradation. This research demonstrates that CBM+ provides not only technical benefits but also strategic value in supporting the transformation of the national MRO industry toward data-driven maintenance practices.

Abstract

Teknologi Swarm drone merupakan inovasi penting dalam operasi militer perkotaan yang kompleks dan dinamis. Penelitian ini menganalisis efektivitas, tantangan, dan implikasi strategis implementasi Swarm drone dalam konteks militer Indonesia. Metode yang digunakan adalah studi literatur kualitatif dengan pengumpulan data melalui pencarian sistematis di database akademik terpercaya dari 2020 hingga 2025. Hasil penelitian menunjukkan bahwa Swarm drone meningkatkan efektivitas operasional melalui koordinasi otonom dan adaptasi formasi di lingkungan perkotaan yang padat. Namun, implementasi menghadapi tantangan teknis, regulasi, dan integrasi kecerdasan buatan. Penelitian menekankan kebutuhan akan roadmap nasional dan kerangka regulasi yang adaptif untuk mendukung pengembangan teknologi ini secara optimal. Implikasi strategis meliputi perubahan paradigma dari operasi berbasis platform tunggal ke sistem jejaring terintegrasi yang menuntut pengembangan strategi counter-Swarm dan kebijakan pertahanan adaptif. Kesimpulan menyoroti perlunya pendekatan holistik yang menggabungkan kemajuan teknologi, aspek etika, regulasi internasional, dan kesiapan sumber daya manusia untuk memastikan operasi militer yang efektif dan berkelanjutan dengan teknologi Swarm drone.
