Abstract

The development of environmentally friendly propellant technology has become a primary focus in the defense industry. Composite propellants, which have traditionally relied on Ammonium Perchlorate (AP), offer high performance but pose environmental concerns due to the emission of corrosive chlorine compounds. This study aims to evaluate the potential use of green oxidizers such as Ammonium Dinitramide (ADN), Hydrazinium Nitroformate (HNF), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) as alternatives to AP. A qualitative literature review method was employed, drawing from various national and international scientific sources. Findings show that ADN and HNF offer promising performance and are more eco-friendly due to no chlorine emissions. However, challenges like thermal stability, hygroscopicity, and high production costs remain. This research highlights the potential of green oxidizers to reduce pollution and enhance national defense industry sustainability.

Abstract

Indonesia aims for 23% renewable energy by 2025 and a 29% reduction in greenhouse gas emissions by 2030 under the Paris Agreement. B35 biodiesel, a blend of 35% palm oil-based biodiesel and 65% diesel, is a key strategic solution for this energy transition. This study, using a mixed method approach with regression analysis, analyzed data from the Ministry of Energy and Mineral Resources and Indonesian palm oil industry reports. It aimed to quantify B35's contribution to the renewable energy mix and project outcomes for a potential B40 policy. An in-depth analysis was conducted to identify the success factors and challenges of biodiesel implementation. Results show B35 biodiesel significantly contributes to Indonesia's renewable energy goals, reaching 38% in 2023 and 38.75% in 2024. Its implementation also led to substantial savings of IDR 120.54 trillion in 2023 and IDR 123 trillion in 2024 by substituting fossil fuel imports. Regression projections suggest that B40 biodiesel could further increase renewable energy contributions to 40.7% with a 15.62 million kL production target in 2025. Additionally, biodiesel usage reduces CO₂ emissions by 8-11% compared to conventional diesel. In conclusion, B35 biodiesel plays a vital role, contributing nearly 40% to Indonesia's national renewable energy. For successful B40 implementation and to optimize biodiesel's role in achieving 2025 targets, a stable Crude Palm Oil (CPO) supply, a USD 4.1 billion infrastructure investment, consistent policy frameworks, feedstock diversification, carbon tax implementation, and strong inter-ministerial collaboration are essential.
