Ketersediaan suku cadang merupakan salah satu syarat untuk menjaga keandalan industri. Oleh karena itu, prosedur pengadaan suku cadang perusahaan harus berhasil dan efisien. Namun, kejadian risiko yang berdampak buruk dalam jangka pendek maupun jangka panjang tetap mungkin terjadi meskipun aktivitas rantai pasok proses pengadaan suku cadang rumit, yang melibatkan banyak pihak, dan ketidakpastian yang muncul akibat perubahan dinamis yang sangat cepat. Menemukan risiko operasional dalam pembelian suku cadang MRO dan mengidentifikasi strategi lain untuk memitigasi risiko ketidaktersediaan suku cadang merupakan tujuan utama studi ini. Untuk mengidentifikasi kejadian risiko dan agen risiko, serta merumuskan tindakan mitigasi agen risiko prioritas berdasarkan nilai Aggregate Risk Potency (ARP) yang dapat menghambat pembentukan agen risiko, studi ini menggunakan metode House of Risk (HOR). 26 kejadian risiko dan 25 penyebab risiko diidentifikasi dari hasil studi. Nilai ARP terbesar digunakan untuk memilih agen risiko prioritas. Metode analisis Pareto digunakan untuk menghasilkan 14 agen risiko, yang memiliki dampak sebesar 81,32% terhadap munculnya peristiwa risiko. Munculnya risiko agen dalam rantai pasokan proses pengadaan suku cadang MRO dapat dikurangi dengan menerapkan 9 strategi mitigasi.

Abstract The availability of spare parts is one of the most important factors in maintaining manufacturing reliability. Consequently, the company's spare parts procurement procedure needs to be successful and efficient. The creation of risk events with detrimental effects in the short and long term may result from the intricacy of supply chain operations in the spare parts procurement process, which involves numerous parties and uncertainties that arise in quick dynamic changes. Finding operational hazards in the purchase of MRO spare parts and identifying other strategies to mitigate the risk of spare parts shortages are the main objectives of this study. In order to identify risk events and risk agents, as well as to develop mitigation measures for priority risk agents based on their Aggregate Risk Potential (ARP) values in order to limit or suppress the formation of risk agents, the House of Risk (HOR) technique was employed in this study. According to the study's findings, there were 25 risk agents and 26 risk events. The greatest ARP value was used to determine priority risk agents, and the Pareto analysis method produced 14 risk agents that were responsible for 81.32% of risk event emergence. The emergence of risk agents in the supply chain process of MRO spare parts procurement can be reduced by using 9 mitigation measures.
