Abstract

This paper examines why the maintenance cost per barrel at a deepwater gas field operating under a cost-recovery production-sharing contract rose 161% in a single year, climbing from USD 0.41/BOE in the prior year to USD 1.07/BOE, even though plant availability stayed above 97%. A risk-based life-cycle cost (LCC) framework is applied to four maintenance strategy alternatives over an eight-year residual contract horizon (2025 to 2032) using primary operational records for 2021 to 2024, supplemented by sensitivity analysis and the Analytic Hierarchy Process (AHP). The deterministic Net Present Cost (NPC) ranking favors contract restructuring as the least-cost option (A2, USD 72.37M, 10% real discount rate). The multi-criteria evaluation, which integrates risk-cost exposure under the safety, efficiency, flexibility, and cost criteria (weights 0.557, 0.286, 0.100, 0.056, CR 0.003), supports condition-based monitoring investment as the recommended strategy (A3, NPC USD 74.51M, AHP composite 0.438). An expected-value analysis estimates that a CBM-enabled 30% reduction in unplanned-event frequency avoids approximately USD 5.9M of production-loss exposure against a USD 2.14M premium over the cheapest alternative, a ratio of roughly 2.8 times. The recommended strategy targets a return to USD 0.85 to 0.90/BOE within the 2026 to 2028 planning horizon. The findings show that under cost-recovery fiscal structures, the cost-cheapest option is not the value-best option once risk-cost exposure is properly weighted.

Abstract

PT National Gas Company Tbk (NGC), as Indonesia’s Subholding Gas under One Energy Group, faces a structural inflection point. Although revenue remained broadly stable, the company’s full-year net profit fell by about 37 percent year-on-year, from approximately USD 340 million in 2024 to USD 215 million in 2025. This margin compression reflects a structural mismatch between maturing upstream pipeline supply in western Indonesia, the company’s growing reliance on LNG to backfill domestic demand, and the price ceilings imposed by the Specified Natural Gas Price regulation on certain industrial sectors. To re-anchor growth, NGC’s Gas Supply & LNG Trading (GSLT) division has begun engaging in international LNG trading, however, the company’s initial 2023–2024 entry under early counterparty arrangement has produced volatile financial outcomes and material legal exposure. An unstructured trading posture is therefore unsustainable, and a structured analytical evaluation of business model alternatives is required. This research addresses three interconnected questions: (1) what factors influence a company’s ability to engage effectively in LNG trading; (2) how common LNG trading business models differ in their key characteristics and trade-offs; and (3) which business model represents the most suitable strategic fit for NGC given its internal capabilities, external risks, and corporate planning constraints. The study adopts a combine qualitative and quantitative methodology, anchored in the Kepner–Tregoe Decision Analysis logic and operationalised through an integrated analytical framework combining Resource-Based View and VRIO for internal analysis, PESTEL and Porter’s Five Forces for external analysis, business model archetype mapping, and Multi-Criteria Decision Analysis (MCDA) using the Analytic Hierarchy Process to rank alternative business models. Primary data come from semi-structured interviews with 12 respondents: 6 internal NGC stakeholders and 6 external stakeholders. Secondary data include NGC’s RJPP (Long-Term Corporate Plan) 2025–2035 LNG Trading projection, FY 2024 and 2025 financial disclosures, regulatory instruments, and industry reports. The internal analysis identifies NGC as fundamentally asset-strong but capability-constrained, physical infrastructure and the embedded role as Indonesia’s national gas aggregator are valuable, rare, and difficult-to-imitate resources, whereas trading capability, front-to-back-office structure, financial-risk hedging, and shipping control are underdeveloped. The external analysis identifies a mixed environment of opportunity and constraint. The MCDA evaluation, weighted by managerial-judgement criteria of strategic fit, financial robustness, risk exposure, capability requirement, implementation complexity, policy alignment, and time-to-market, ranks the hybrid asset-backed portfolio model as the most suitable strategic posture for NGC, ahead of utility/single-buyer, asset-backed integrated, pure portfolio, and merchant-trader archetypes. The ranking is robust under three sensitivity scenarios (One Energy Group–NGC novation completion, restrictive LNG export–import permits, and base-case continuity). The research recommends a phased implementation, a 0–12-month foundation phase to consolidate trading governance and front-to-back-office structures, a 1–3-year anchor build-out integrating novated One Energy Group LNG cargoes and securing shipping and regasification optionality, and a 3–5-year regional scale-up serving Southeast Asia’s emerging. The framework is intended as a decision-support tool to be revisited as market conditions, regulatory frameworks, and NGC’s capability base evolve.

Abstract

This study develops a SMART-based decision-making framework to prioritize Energy Efficiency initiatives in an Indonesian retail company. PT Prima Retail Lestari (PT PRL) is a retailer which faces budget and operational constraints, while several Energy Efficiency initiatives are available and have different financial, ESG, feasibility, and risk implications. An applied case study method will be used. The data will be gathered through semi-structured interviews, questionnaires, and document analysis. Situational Appraisal and Kepner-Tregoe Problem Analysis will be used to clarify the decision making gap, while the SMART method will be used to compare five initiatives: Refrigerant Transition, Rooftop Solar Panel Implementation, LED Lighting Transition, Water Loop Refrigeration System, and HVAC Efficiency Improvement. The result shows that ESG contribution and financial impact are the most important criteria with normalized weights of 0.30 and 0.28, respectively. Rooftop Solar Panel Implementation gets the highest weighted score of 4.00, followed by LED Lighting Transition with 3.92 and Water Loop Refrigeration System with 3.86. The study recommends prioritizing rooftop solar, implementing LED transition in parallel, and preparing water loop refrigeration as a long term initiative.

Abstract

Heavy-equipment delivery by Landing Craft Tank (LCT) is critical to mining operations in Indonesia’s archipelagic regions, yet routing decisions are often made without structured analytical support. This study develops a decision-making framework for optimizing LCT delivery at a mining-logistics company that relies predominantly on single-origin–single-destination (SOSD) voyages. Using a quantitative-dominant single-case design, 55 LCT voyages from 2025 (498 equipment-unit movements) were analysed through voyage-level key performance indicators—load factor, cost per ton, and cost per nautical mile. The Analytic Hierarchy Process (AHP) structured the choice between SOSD and multi-origin–multi-destination (MOMD) routing across six criteria, complemented by thematic analysis of seven expert practitioners and Failure Mode and Effects Analysis (FMEA). The fleet recorded a low mean load factor of 27.7%, with 54 of 55 voyages below 50%. The multi-stop voyages observed in practice were not cheaper than SOSD, indicating that consolidation alone does not guarantee savings. AHP ranked SOSD first (global priority 0.540 versus 0.460). The study contributes a managerially usable, data-driven framework integrating performance measurement, multi-criteria evaluation, and risk assessment to guide LCT routing decisions.
