Abstract

Surfactants are generally produced from petroleum and natural gas derivatives while petroleum reserves are depleting and cannot be renewed. This has the potential to cause an energy crisis on a global scale in the future. To solve this problem, alternative renewable raw materials are needed that can help make surfactants that are environmentally friendly, namely raw materials sourced from vegetable oil. One of the anionic surfactants that can be made from plant materials and is renewable is Methyl ester sulfonate. The purpose of this study was to determine the effect of the mole ratio, temperature and percent of the catalyst and the duration of the sulfonation reaction using NaHSO3 reactants on the resulting MES. The production process of the MES surfactant is carried out by reacting the methyl ester with the sulfonation reagent in the form of NaHSO3 and CaO catalyst in the sulfonation reactor. The results showed that MES had the best characteristics with an optimum state in the ratio of 1: 1.5 mole ratio with 1% CaO catalyst and a temperature of

Abstract

AbstrakInfrastruktur energi merupakan struktur kebutuhan sistem fisik publik dan swasta yang digunakan untuk produksi, transformasi, konversi, transportasi atau distribusi energi. Dalam hal teknologi energi, banyak terjadi pengembangan teknologi energi seperti, PV, smart-grid dan sebagainya. Dalam infrastruktur energi untuk militer diperlukan infrastruktur yang memiliki efisiensi tinggi dan andal. Pada penelitian ini, penulis membandingkan teknologi saat ini yang digunakan dalam infrastruktur militer dan proyeksi teknologi infrastruktur energi masa depan berdasarkan literature review. Sistem distribusi sumber energi berbasis generator sel bahan bakar, hidrogen, dan sistem penyimpanan energi diprediksi akan menjadi energi untuk militer masa depan berdasarkan jaringan smart-grid.Kata Kunci: Energi, Infrastruktur, Mikrogrid, Militer, Teknologi. AbstractEnergy infrastructure is a structure of the needs of public and private physical systems used for the production, transformation, conversion, transportation or distribution of energy. In terms of energy technology, there is a lot of development of energy technology such as, PV, smart-grid and so on. In the energy infrastructure for the military is needed infrastructure that has high efficiency and reliability. In this study, the authors compared the current technology used in military infrastructure and projections of future energy infrastructure technologies based on literature review. The distribution system of energy sources based on fuel cell generators, hydrogen, and energy storage systems is predicted to be energy for the military of the future based on smart-grid networks.Keywords: Energy, Infrastructure, Microgrids, Military, Technology.
