Abstract
Hingga tahun 2021, Indonesia memiliki 613 anjungan terpancang lepas pantai, dan sebanyak 100 di antaranya (16,3%) telah berhenti beroperasi. Sebanyak 335 anjungan (54,6%) telah berumur di atas 20 tahun dan berada dalam kondisi yang berpotensi membahayakan integritas struktur dan lingkungan sekitarnya. Padahal biaya decommissioning per anjungan dapat mencapai USD 6–7 juta, dengan estimasi total biaya nasional mencapai Rp 13 triliun. Kompleksitas pengambilan keputusan meningkat karena keterlibatan multi-stakeholder dengan kepentingan yang saling bertentangan, seperti perusahaan migas, kontraktor, regulator, dan masyarakat pesisir. Penelitian ini membangun model pengambilan keputusan multi-stakeholder berbasis pendekatan kuantitatif untuk menentukan strategi decommissioning yang optimal. Pengumpulan data dilakukan melalui survei kepada 21 responden ahli dari industri hulu migas didapatkan 3 faktor utama yaitu: risiko lingkungan dan kesehatan (A1, A7, B9, C1, D2, dan D6), kesiapan teknis dan infrastruktur (B8, E3, dan E4), serta lingkungan eksternal dan kebijakan (C2, C3, dan C4). Penelitian menunjukkan bahwa berdasarkan value-based perbandingan biaya dan fungsi, alternatif leave in place memperoleh value paling tinggi (1,366). Tahap akhir menggunakan cooperative game theory untuk menjawab permasalahan multi-stakeholder dan didapatkan hasil nilai pay-off tertinggi untuk alternatif partial removal dengan skor koalisi gabungan sebesar 1,042, yang menunjukkan tingkat kepuasan dan konsistensi tinggi antar stakeholder.

As of 2021, Indonesia has 613 offshore docks, and as many as 100 of them (16.3%) have ceased operations. A total of 335 platforms (54.6%) are over 20 years old and are in conditions that have the potential to endanger the integrity of the structure and the surrounding environment. In fact, the cost of decommissioning per platform can reach USD 6-7 million, with an estimated total national cost of Rp 13 trillion. The complexity of decision-making increases due to the involvement of multi-stakeholders with conflicting interests, such as oil and gas companies, contractors, regulators, and coastal communities. This study builds a multi-stakeholder decision-making model based on a quantitative approach to determine the optimal decommissioning strategy. Data collection was carried out through a survey of 108 expert respondents from the upstream oil and gas industry, 3 main factors were obtained, namely: environmental and health risks (A1, A7, B9, C1, D2, and D6), technical and infrastructure readiness (B8, E3, and E4), and external environment and policies (C2, C3, and C4). The research shows that based on the value-based comparison of costs and functions, the leave in place alternative obtained the highest value (1.366). The final stage used cooperative game theory to answer multi-stakeholder problems and obtained the highest pay-off value for partial removal alternatives with a combined coalition score of 1.042, which shows a high level of satisfaction and consistency between stakeholders.
