Thermal Analysis of Discharge Valve Overheating in the Make-Up Side of Compressor 200-C-1-A/B Djeli Satrijo Toni Prahasto Ojo Kurdi Immanuel Simanjuntak Ian Yulianti Volume 2, Issue 5, Pages 1-6, May 2025 Reciprocating compressors are essential in the oil and gas industry for their ability to deliver high-pressure gas and maintain process stability under varying loads. At PT Kilang Pertamina Internasional Refinery Unit II Dumai, the 200-C-1-A/B reciprocating compressor plays a vital role in regulating vessel pressure in Unit 200 Area HSC by supplying compressed mixed gas. During operational m... Read More Article DOI: doi.org/10.47001/CJESR/2025.205001
Effect of Talc Addition on the Mechanical Properties of RTV Silicone Rubber: Comparative Study of RTV 497, RTV 52, RTV 10A, and RTV 00A Susilo Adiwidyanto Yusuf Umardani Agus Suprihanto Fernando Pandiangan Volume 2, Issue 5, Pages 7-12, May 2025 This study explores the influence of talc as a reinforcing filler on the mechanical properties of four types of RTV silicone rubber—RTV 497, RTV 52, RTV 10A, and RTV 00A. Specimens were fabricated with varying talc contents (5%, 10%, 15%, 20%, 25%, and 30% by weight) and subjected to tensile and compressive testing in accordance with ASTM standards. The mechanical performance, particularly ... Read More Article DOI: doi.org/10.47001/CJESR/2025.205002
Aerodynamic Analysis Airfoil on an Airplane Wing Using Computational Fluid Dynamic Yusuf Umardani Ojo Kurdi Djoeli Satrijo Aditya Daffa Pambudi Ian Yulianti Volume 2, Issue 5, Pages 13-18, May 2025 Analysis of the aerodynamic performance of an airfoil cross-section is very necessary to determine the maximum lift force that occurs and the forces acting on the airfoil cross-section such as Drag Force and Lift Force. In this study, a series airfoil cross-section design, a symmetrical airfoil, was tested using Fe software with input of fluid velocity, viscosity and density so that the distr...
