Abstract

This research aims to examine of finding best choice type of contract for supporting critical engines operation and performance (including for maintenance and repairment). The researchers used Multi Criterion Decision-Making method with tool of Analytical Hierarchy Process, which data gather from survey and sampling from practitioners. They also used simplification of contract types from critical variable of contract such as price, quality, and delivery criterion. Criterion acquired from Forum Group Discussion with Subject Matter Expert. The research discovered that existing contracts vary and still many cases of unplanned shutdown lack of support from spare parts and other supports as a product form existing contracts.

Abstract

This paper proposes a comprehensive solution to enhance embankment stability assessment in mining company's tailings management operations through the implementation of Fiber Optic instrumentations. The current monitoring solutions lack real-time capabilities, hindering timely assessment and mitigation of embankment stability issues. Fiber Optic cables provide sensing capabilities to detect vibrations and measure temperature variations, enabling early detection of structural issues within embankments. Real-time monitoring allows continuous assessment and immediate identification of potential risks. Implementing fiber optic cable instrumentations enhances embankment stability assessment, ensuring safety and minimizing failures. Data-driven decision-making is empowered through accurate and real-time data, enabling efficient resource allocation. The implementation follows a DMAIC (Define, Measure, Analyze, Improve, Control) approach, ensuring a comprehensive analysis and step-by-step plan. In conclusion, fiber optic cable instrumentations offer valuable enhancement to embankment stability assessment in mining's tailings management operations. Real-time monitoring, accuracy, and precision contribute to proactive measures and improved decision-making. Implementing this solution strengthens embankment stability practices, safeguards surrounding areas, and maintains regulatory compliance, fostering resilience and sustainability in mining operations.

Abstract

This study aims to examine how business process reengineering accompanied by the implementation of an ERP system (Odoo) can improve the efficiency and accuracy of internal processes in a multi-unit SME in Indonesia. The background to this study is the challenges of cross-unit business coordination, manual process inefficiencies, and lack of data visibility that impact internal supply chain performance. This research employs a qualitative approach through in-depth interviews and field observations, verified through business process modeling and simulation using Bizagi Modeler.The research findings indicate that the business processes prior to the redesign, with ERP implementation, were characterized by fragmented coordination of raw materials, slow approval processes due to manual procedures, and inaccurate data recording. Projected results indicate that process time can be reduced by up to 75%, inventory discrepancies can be reduced by 15% to 3-5%, and cross-unit miscommunication can be significantly reduced. Simulation results using Bizagi show that the total number of lots that can be produced over 60 days increases from 980 to 991 lots. The average time for internal production can be reduced from 3 days and 5 hours to 2 days and 17 hours as recording accuracy improves through the ERP system. These findings emphasize the importance of in-depth process analysis, top management commitment, and structured change management strategies for the successful implementation of ERP systems.
