A Validation of the Analytical Hierarchy Process (AHP) for Ranking Geothermal Potential for Next PLNs Project: An Academic Expert Perspective

Abstract

The study evaluates the geothermal potential of Indonesia using the Analytical Hierarchy Process (AHP). AHP was employed to rank geothermal sites for development, considering criteria such as resource potential, infrastructure readiness, economic feasibility, and socio - cultural impacts. Academic expert judgment, while inherently subjective, is incorporated to provide structured comparisons among multiple geothermal fields. This study highlights the application of AHP in providing transparent, objective rankings for geothermal site prioritization, which is essential for strategic planning in Indonesia’s energy transition. The results suggest that economic feasibility and resource potential are key drivers in geothermal field selection, particularly for the Ulumbu and Tulehu fields that owned by PT PLN (Persero). These findings have direct implications for future geothermal investments and policy decisions in Indonesia. The study highlights the potential of AHP method in guiding policy and investment decisions for geothermal energy development PLN’s geothermal fields for further study.
