This study aims to describe students' STEM skills after the implementation of the Project Based Learning (PjBL) model in welding teaching materials at the Mechanical Engineering Education Study Program, Faculty of Teacher Training and Education, Universitas Sriwijaya. The study used a descriptive quantitative method with a total sampling technique involving 85 students taking the TIG-MIG Weldin…
This study aims to analyze the effect of Selective Laser Melting (SLM) process parameters on the microhardness and microstructure of Ti-6Al-4V Grade 23 titanium alloy. This material is widely used in biomedical and aerospace applications due to its high strength-to-weight ratio, good corrosion resistance, and excellent biocompatibility. However, laser-based additive manufacturing processes ofte…
