This study reported the leakage current and resistance value in Silicone Rubber (SiR) insulation material mix Silicone dioxide (SiO2) filler by applying voltage of 220 V, 500 V, and 1000 V. Test samples were sheet form with dimensions of 50 × 25 mm and thickness 1 mm. Test are carried out using an Aluminum tape electrode system glued on both sides of the object with a gap distance of 20 mm. Th…
The study focuses on advancing dissimilar metal welding techniques. The intense heat during welding leads to thermal expansion or contraction of the metal upon cooling, resulting in residual stresses in the weld area. Post Weld Heat Treatment (PWHT) is employed to alleviate these residual stresses. The research investigates the impact of PWHT on the mechanical and physical properties of joints …
The development of sustainable construction has been the subject of research recently. due to the significant range of carbon dioxide emissions involved in the production of regular Portland cement. Therefore, in order to support sustainable material, another material must be found. A different approach is to use an alternative material, such as fly ash, in place of the cement. Alkaline activat…
The research designs a fuel cell based on Natural Uranium Metal (U-10%wtZr) with the addition of minor actinide such as Am-241, Np-237 and Cm-244. The coolant used is Helium and the cladding is Stainless Steel (SS316). This fuel cell is pin shaped with a diameter of 1,4 cm. The fuel cell was tested with 5% enrichment without minor actinide and then minor actinide was added alternately. Calculat…
Baterai lithium-ion telah digunakan sebagai media penyimpan energi listrik portabel karena memiliki densitas energi tinggi dan siklus hidup yang panjang. penyimpanan energi pada baterai lithium-ion disebabkan oleh polimer elektrolit. Polimer elektrolit yang digunakan biasanya adalah solid polymer elektrolyte. Solid polymer electrolyte memiliki polimer inang. Salah satu polimer yang sering digun…
Telah dilakukan pembuatan komposit anoda TiO2 fasa anatase-rutile yang menggunakan metode solid state reaction dengan bahan baku TiO2. Pembuatan komposit dilakukan dengan variasi penambahan bahan TiO2 fasa anatase dan TiO2 fasa rutile. Prekursor TiO2 fasa anatase dioven pada suhu 80oC selama 4 jam, sedangkan prekursor TiO2 fasa rutile disinter pada suhu 800oC selama 4 jam. Karakterisasi yan…
