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

This study investigates the persistent delays in procurement lead time for Agreed Stock Items (AGSI) within the Procurement Division of PT Alami Mandala Indonesia (AMI). AGSI refers to repeat-order materials that are already agreed upon in specification and usage, and therefore, ideally should be processed swiftly. However, data revealed that the actual PR to PO lead time consistently exceeds the company's OKR target of 14 days, creating operational inefficiencies, potential equipment downtime, and financial losses. This issue is especially critical in the context of AMI's mining operations, which are highly dependent on timely and uninterrupted supply of materials to sustain production activities. A mixed-methods research approach was adopted, combining qualitative insights from semi-structured interviews with procurement personnel and quantitative analysis of historical procurement data from SAP ERP systems spanning 2023–2024. Through this approach, the study identified key bottlenecks including repetitive manual bidding processes for the same items, incomplete or unclear material specifications, limited supplier pools, and logistical difficulties stemming from the company's remote mining sites. These issues were further structured and analyzed using a Fishbone Diagram and Current Reality Tree (CRT) to identify root causes and systemic weaknesses. To address these challenges, a set of alternative solutions was developed and evaluated using a weighted scoring method based on four criteria: potential for lead time reduction, implementation effort, cost implications, and impact on material availability. Among these, the implementation of Long Term Agreements (LTAs) with key suppliers was identified as the most feasible and impactful solution.

Abstract

A long standing English language school in Indonesia called ITTR English Course has seen flat profits even though student numbers have remained steady, which suggests there are deep problems with the quality of its services. The goal of this research is to assess current service standards and develop strategic improvements that will boost student satisfaction, increase retention, and lift the institution's financial performance. Using a sequential explanatory mixed-methods approach, this research combined quantitative SERVQUAL surveys analyzed through Structural Equation Modeling (SEM) with qualitative NVivo analysis to pinpoint service issues. Problems were diagnosed using Fishbone and Current Reality Tree (CRT) methods, ranked through Analytic Hierarchy Process (AHP), and addressed by developing action strategies with the House of Quality (HOQ) and the Plan–Do–Check–Act (PDCA) framework. Based on the study, student satisfaction is most heavily influenced by the reliability and assurance aspects of service quality. Satisfied students then become loyal customers, which directly supports the institution's bottom line. The author recommends focusing on teacher training, classroom facilities, and communication speed, alongside implementing scheduled feedback systems. In conclusion, managing service quality effectively is demonstrated to be the best way to secure ongoing student fulfillment, retention, and profitability.

Abstract

Background: Following organizational restructuring, Procurement and Contract Management (PCM) functions across Subholding entities in Indonesia’s upstream oil and gas sector show variation in Service Level Agreement (SLA) achievement linked to differences in work method, personnel allocation, and coordination practices; external factors such as regulatory requirements and digital system transformation may further shape these outcomes. Objective: This study analyzes SLA performance variation across Subholding entities and examines how work method, personnel allocation, and coordination influence procurement and contract management performance, extending operations-management literature on work specialization beyond single-sector confirmation toward context-specific evidence from a regulated, project-based industry. Methods: Using a convergent parallel mixed-method design (Creswell & Plano Clark, 2018), quantitative data from six Subholding entities (2024) were analyzed together with qualitative data from interviews and FGDs; the two strands were collected concurrently and merged during interpretation to provide complementary explanatory depth. Results: Split work methods achieved 45% faster SLA completion than end-to-end methods. Contract Assignment Ratio showed a weak negative but statistically insignificant correlation with SLA Compliance (Pearson r = -0.251, p = 0.631; n = 6), indicating limited statistical power from only six regional observations and suggesting that process coordination, execution quality, and capability differences, rather than personnel volume alone, more strongly explain SLA variation. Conclusion: Split work methods improve SLA performance through role specialization and coordination, while personnel allocation alone does not determine outcomes. Findings offer practical guidance for procurement governance, SLA monitoring, and capability development; generalization beyond a single industrial sector and a small regional sample remains limited.
