Abstract

This study aims to determine the best location for relocating PT Pertamina Patra Niaga's High Sulfur Fuel Oil (HSFO) Supply Point in East Java to improve distribution efficiency and reduce logistics costs. The research method used is the Fuzzy Analytical Hierarchy Process (F-AHP) approach, which combines quantitative and qualitative analysis through expert interviews and focus group discussions (FGDs) to assign weights to factors and subfactors influencing location selection. The results indicate that location accessibility has the highest weighting of 0.614, surpassing financial factors at 0.386. The market location subfactor is the top priority, with a weighting of 0.420, as proximity to HSFO consumption centers provides significant distribution efficiency. Based on the F-AHP analysis, TBBM Tuban was selected as the most optimal location with a score of 0.567, surpassing Camplong Madura, Malang, and Madiun. The study concludes that relocating the Supply Point to Tuban is a strategic move that can increase cost efficiency by up to 25%, accelerate distribution, and strengthen the company's competitiveness and operational sustainability.   Keywords: HSFO, Location Selection, Fuzzy AHP, Accessibility, Distribution Efficiency

Abstract

With the increasing demand for road durability driven by rapid economic development, innovative and sustainable approaches are essential to improve the strength and service life of road pavements. This study investigates the use of teak wood powder waste (TWPW) as a cost-effective and environmentally friendly filler material in Hot Rolled Sheet – Wearing Course (HRS-WC) asphalt mixtures. Utilizing bio-waste not only supports circular economic principles but also offers economic benefits by reducing reliance on conventional, more expensive fillers. The research evaluates various TWPW concentrations (0%, 0.3%, 0.6%, and 0.9%) and their effects on key Marshall test parameters, including stability, flow, Marshall Quotient (MQ), Voids in Mineral Aggregate (VMA), Voids in Mix (VIM), and Voids Filled with Asphalt (VFA). Samples were prepared using both dry and wet methods in accordance with Bina Marga (2018) specifications. The results indicate that the optimum filler content was 0.9% for the dry method (stability: 1042.68 kg) and 0.6% for the wet method (stability: 1161.14 kg). SEM analysis confirmed that filler dispersion significantly influences the internal structure and porosity of the mixture. At 0.3% and 0.6%, the filler was more evenly distributed, leading to improved compaction and mechanical performance. Conversely, agglomeration at 0.9% increased voids and reduced compaction quality. This study demonstrates that TWPW can serve as a viable low-cost filler alternative, maintaining pavement performance while reducing material costs and environmental impact. The findings support the adoption of sustainable waste utilization practices in road construction.

Abstract

Objectives: This study aims to identify the criteria that must be considered in selecting alternative solution for the Tower Intersection Point (TIP) 182 issue on Buru Island, Maluku. The problem emerged after a landslide at the foundation of TIP 182 caused the leg C foundation to sink and the surrounding ground to crack. The research seek to analyze the best alternative solution using the Analytical Hierarchy Process (AHP) method and evaluate the sensitivity of the selected criteria to ensure the robustness of the chosen alternative.Methodology: Data were collected through Focus Group Discussion (FGD) to formulate relevant criteria and alternative solutions, as well as questionnaires to determine the weight of each criterion. The Analytival Hierarchy Process (AHP) was employed to prioritize and rnk the alternatives based on the established criteria. Sensitivity analysis was conducted to assess the stability of the selected alternative under change in criteria weighting.Findings: The FGD identified three alternatives; relocation of the TIP 182, redesign of TIP 183 and cutting slope. Five main criteria were analyzed in depth; technical aspects, resources, cost, duration and risk. The AHP results indicate that the redesign TIP 183 alternatives is the most optimal solution for addressing the problem at TIP 182 on Buru Island. Sensitivity analysis further confirms that variations in the weights of the technical, resources, cost, duration and risk criteria do not significantly alter the ranking position of the redesign TIP 183 alternative as the most superior option.Conclusion: The study concludes that redesign TIP 183 is the most appropriate and robust alternative solution for resolving the TIP 182 issue. The application of AHP provides a structured and objective decision-making framework that supports effective project completion and practical implementation on the field, while also offering a foundation for future related research.
