Abstract

PT Pertamina Hulu Mahakam (PHM) is an oil and gas exploration and production operator in the Mahakam block, East Kalimantan, and conducts drilling operations for development and exploration wells using five offshore rigs. Mudlogging services are crucial for real-time geological monitoring and operational safety in offshore drilling. Mudlogging plays a crucial role in maintaining well integrity and enhancing drilling efficiency. From 2019, these services have been delivered through two major contracts, one awarded to PTGI and the other to a consortium between PTEN and PTGS. However, the second period (2022-2024) saw a sharp decline in performance, resulting in an estimated USD 350,000 in rig standby costs. This research aims to identify the root causes of the decline in mudlogging performance and propose practical improvement strategies to restore operational reliability and minimize non-productive time (NPT). A mixed-method approach was adopted, combining structured interviews with key stakeholders, and Likert-scale questionnaires were collected from the stakeholders and expert. Qualitative data analysis, utilizing root cause methodologies, fishbone diagrams, and current reality trees (CRTs), revealed that the absence of clear governance structures and role clarity led to weak coordination, delayed decisions, ineffective communication, and inadequate technical oversight. Insufficient training, high turnover, and limited motivation among contracted personnel in one of the consortium company were also identified as contributing factors in this research. The analytic hierarchy process (AHP) was applied to prioritize improvement strategies, with restructuring the consortium scoring highest and training enhancement being the most impactful levers for restoring performance.

Abstract

The persistence of manual weighing practices in coal transportation has led to significant revenue losses at PT Borneo Indobara, with a recorded discrepancy of -1.218% in coal tonnage reconciliation during Q4 2023—exceeding the company’s ±0.5% threshold. This research aims to identify the root cause of this issue, evaluate alternative solutions, and propose a strategic implementation plan to eliminate manual weighing. Employing the Current Reality Tree (CRT) method, the study found that the core issue was the absence of prior investigation into weighing alternatives. Using both primary (interviews, FGDs, observations) and secondary data (company reports, standards), three alternatives—Weighbridge, Low-Speed Weigh-in-Motion (LS-WIM), and High-Speed Weigh-in-Motion (HS-WIM)—were assessed using the Analytic Hierarchy Process (AHP) based on accuracy, productivity, and investment cost. The LS-WIM alternative emerged as the most optimal, scoring 0.37, due to its high productivity and moderate cost, despite slightly lower accuracy. Implementation is planned through a structured PDCA-based approach, covering proposal development, tendering, construction, and commissioning. With LS-WIM's expected accuracy of ±2%, the study projects a reversal of revenue loss into a gain of approximately USD 314,963.27, illustrating the business value of replacing manual weighing. This research contributes a novel integration of CRT and AHP methodologies in the coal logistics context and provides an actionable, stakeholder-informed roadmap for technology implementation. Future studies are encouraged to explore long-term performance, hybrid system integration, and cross-industry applicability of weigh-in-motion technologies.

Abstract

Indonesia’s growing coal production has increased pressure on port logistics, particularly tugboat operations that are vital for barge maneuvering. PT PIT, the sole tug service provider for PTBA, currently operates with only two tugboats, resulting in limited capacity and increasing delays in coal shipments. This study aims to develop a decision support framework to optimize tugboat capacity expansion at PT PIT’s dual-port operations (Kertapati and Kramasan). A mixed methods approach is employed, combining quantitative modeling (queuing theory, financial feasibility, and project scheduling) with qualitative insights from stakeholder discussions. The analysis finds that expanding the fleet from two to four tugboats raises daily barge throughput from three to nearly ten, improves turnaround times, and increases PT PIT’s annual net revenue by approximately IDR 19.9 billion. Three procurement alternatives new purchase, operational lease, and financial lease are evaluated using the Analytical Hierarchy Process (AHP), with operational leasing emerging as the most viable due to its flexibility and lower risk. Risk assessment, following ISO 31000:2018 guidelines, identifies 15 critical risks, including capacity shortfalls and mechanical failures, with mitigation strategies proposed. The project is scheduled using PERT and Gantt methods, providing a roadmap for implementation by 2026. This integrated framework supports scalable, cost-efficient, and risk-mitigated logistics performance to meet Indonesia’s rising coal export demands.

Abstract

Coal unloading operations at Kertapati Port face persistent inefficiencies due to the adhesive nature of low-rank coal, which frequently sticks to the inner surfaces of train carriages, causing delays, increased operational costs, and reduced unloading performance. This study aims to formulate a feasible and effective strategy to mitigate the issue of sticky coal during the unloading process to support the achievement of production and transportation targets. Using a mixed-methods approach, the study integrates the Current Reality Tree (CRT) to identify root operational bottlenecks, the Analytic Hierarchy Process (AHP) to prioritize technical solutions, the Critical Path Method (CPM) and PERT for project scheduling, and financial feasibility analysis through NPV, IRR, and Payback Period. The results indicate that applying a stainles steel lining to the interior of boat-type train carriages is the most effective solution to reduce coal adhesion. Financially, the proposed investment is attractive, yielding an IRR of 66%, an NPV of IDR 29.1 billion, and a payback period of two years. The project is scheduled to begin on August 1, 2025, and complete by November 14, 2025. Continuous risk management measures are also planned throughout implementation. This integrated solution not only addresses the immediate operational inefficiencies but also supports long-term improvements in coal handling reliability and port logistics performance.

Abstract

This study addresses operational challenges at Kertapati Port, where barge delays, poor stakeholder coordination, and lengthy administrative processes hinder efficiency. Using the Current Reality Tree (CRT) analysis, the research identifies root causes that reduce jetty throughput and extend vessel waiting times, leading to higher operational costs. To overcome these issues, three solutions were proposed: (1) developing integrated Standard Operating Procedures (SOPs) for berthing/unberthing and administration, (2) adding standby tugboats to ensure smoother berthing operations, and (3) decentralizing administration through an operational office at the jetty. The Analytical Hierarchy Process (AHP) was applied to prioritize these alternatives, while financial feasibility was evaluated using Net Present Value (NPV) and Internal Rate of Return (IRR). Results indicate that implementing integrated SOPs is the most effective solution, significantly reducing idle time and enhancing loading and unloading processes. A 2025 field trial of draft SOPs improved coal loading efficiency to an average of 500 MT/hour, with potential for notable annual throughput growth. Cost simulations suggest savings of thousands of USD per month, mainly by lowering demurrage costs. Furthermore, a real-time digital monitoring system has improved coordination, administrative speed, and schedule accuracy. The study recommends continuous evaluation using Key Performance Indicators (KPIs) and the Theory of Constraints (TOC) to sustain improvements and foster future innovations.

Abstract

Effective inventory management can reduce costs, minimize waste, and ensure product availability, directly impacting a supermarket’s revenue and operational efficiency. This study aims to investigate and improve inventory management policies for perishable items at H Supermarket, located in Riau. The research addresses fluctuating revenue and the gap between target and actual profit by optimizing inventory management through different policies. It specifically addresses the challenges of managing inventory for bread and fruits, which contribute significantly to the supermarket's revenue but are prone to high levels of waste and stockouts due to their short shelf lives. The research employs both qualitative and quantitative methods, including interviews with key stakeholders and analysis of three years of sales data, to identify root causes of inventory inefficiencies. Two distinct inventory policies were analyzed: a continuous review system for bread and a periodic review system for fruits. The continuous review system allows for real-time inventory monitoring, enabling more responsive restocking processes. In contrast, the periodic review system schedules inventory checks at regular intervals, optimizing the balance between freshness and stock levels. The results indicate that the continuous review system significantly reduces total annual costs for bread by approximately 61.4%, while the periodic review system, with a five-day review period, effectively manages fruit inventory, reducing annual costs by 19.1%. The research underscores the importance of tailored inventory management strategies for different types of perishable items. It highlights the need for accurate inventory tracking systems and comprehensive staff training to ensure precise inventory records. The findings suggest that implementing these optimized inventory policies can substantially enhance operational efficiency and reduce waste.

Abstract

This research aims to develop a strategic plan for power infrastructure to support the expansion of production capacity at CVM CORP, with a particular focus on the Eastern Block. The implementation of Eco Mechanized Mining has encountered several key obstacles, including insufficient power supply capacity, high operational electricity costs, slow response to power outages, and significant delays in the development of a new Switching Station (SS), which has been under planning since 2018. Through Current Reality Tree (CRT) analysis, the main root cause was identified as the overreliance on SS TEU as the sole power source for the entire operational zone. To address these issues, the proposed strategy includes the development of a new Switching Station near the company’s PLTU (steam power plant), determination of the optimal site using the Analytic Hierarchy Process (AHP), project scheduling via the Critical Path Method (CPM), cost-efficiency evaluation using full costing and the Levelized Cost of Electricity (LCOE), and investment feasibility analysis utilizing IRR, NPV, and Payback Period metrics. Additionally, the load distribution between SS TEU and the proposed new SS has been redesigned to enhance power efficiency and lower electricity expenses. The results show that a hybrid electricity supply model (PLN–PLTU) substantially reduces electricity costs and helps achieve production targets. The investment also demonstrates strong financial viability, with an IRR of 1398%, a Net Present Value (NPV) exceeding IDR 4.47 trillion, and a payback period of just one year. Project implementation is targeted to start by July 19, 2025, and be completed before October 21, 2026, with continuous risk mitigation throughout the execution phase. This comprehensive strategy ensures greater reliability of the power system and strengthens long-term operational resilience for CVM CORP.
