Abstract

Penelitian ini menganalisis perubahan mikrostruktur dan sifat mekanik material riser walltube GB5310 20G yang mengalami kegagalan akibat long term overheating. Fokus penelitian ini adalah pada pengamatan mikrostruktur menggunakan Scanning Electron Microscope (SEM) serta pengukuran kekerasan material. Hasil uji SEM mengungkap adanya pertumbuhan butir signifikan dan presipitasi karbida pada batas butir yang berperan penting dalam memicu kegagalan material. Uji kekerasan menunjukkan adanya penurunan kekerasan material akibat pelunakan yang dihasilkan dari overheating jangka panjang. Temuan ini dapat membantu dalam memahami penyebab kegagalan pada material riser walltube dan memberikan wawasan penting untuk pemeliharaan dan desain material boiler.

Abstract

RM Riung Gunung Malino, located in Gowa, faces a major challenge in inventory management, as stock recording of raw materials and products is still carried out manually, making it difficult to monitor inventory accurately. This issue leads to overstocking or stock shortages, which reduce operational efficiency. This community service program was implemented to provide solutions through intensive assistance in structured and applicable inventory management training. The solutions offered include the implementation of a digital stock recording system using the inventory module in the Odoo application, the development of a more systematic manual format based on the concepts of safety stock, Reorder Point (ROP), and Economic Order Quantity (EOQ), as well as regular stock monitoring training. The results of the program show an improvement in the partner’s understanding and skills in managing inventory, as evidenced by the ability to create more organized stock records, calculate raw material needs, and determine reorder points accurately. The implemented recording system has proven effective in reducing the risk of stockouts and overstocking, thereby increasing operational efficiency. In addition, the partner has become more confident in managing their business sustainably. Thus, this program provides a tangible contribution to enhancing the competitiveness of culinary MSMEs while promoting business sustainability through effective and measurable inventory management.
