SUMMARY. Nursyifaulkhair et al., in their paper, investigate the welding of American Society for Testing Materials (ASTM) A36 steel plates using shielded metal arc welding (SMAW) and evaluate the effect of welding parameters on mechanical and microstructural properties. Fa’alih et al., in their paper, analyze the techno-economic feasibility of a hybrid microgrid system designed to support commercial green tourism infrastructure on Kei Kecil Island, Southeast Maluku. Budiono et al., in their paper, developed a portable laser engraving system that integrates an APM32F103 microcontroller, external flash memory (25Q128JV), and an FSC-BT986 Bluetooth module with an Android-based engraver application. Syaripuddin et al., in their paper, conducted hard-facing with a single layer using an HV 800 electrode with a 1G weld position using various currents. After welding, the sample was quickly immersed in distilled water. Setiawan (a) et al., in their paper, investigate the wait time associated with decreased productivity, which is the longest component of the installation process. Subeno et al., in their paper, investigate the effectiveness of the epoxy coating system on NEW773CAT heavy equipment unit operating in a mining environment. Wahyudi and Ismail, in their paper, characterize and compare Indonesian AISI 316L stainless steel with two commercial femoral stem implants used by patients, namely XYZ products from the United States and ABC products from India. Setiawan (b) et al., in their paper, design and analyze a coconut milk pressing machine, employing a counter-rotating two screw shafts configuration as an alternative to commonly used single-screw systems.
