Abstract
ABSTRAK PT MNJ merupakan perusahaan manufaktur yang bergerak dalam industri tekstil, khususnya pada proses produksi menggunakan mesin circular knitting. Dalam aktivitas operasionalnya, perusahaan sering menghadapi permasalahan berupa tingginya frekuensi kerusakan mesin yang berdampak pada meningkatnya downtime serta menurunnya output produksi. Kondisi ini menunjukkan bahwa perusahaan belum memiliki sistem manajemen risiko yang terstruktur untuk mengidentifikasi, menganalisis, dan memitigasi risiko pada mesin produksi. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis risiko kerusakan mesin circular knitting serta menentukan strategi mitigasi yang tepat guna meminimalkan dampak risiko. Metode yang digunakan adalah House of Risk (HOR) dan Root Cause Analysis (RCA). Metode HOR digunakan untuk mengidentifikasi risk event dan risk agent, serta menentukan prioritas risiko berdasarkan nilai Aggregate Risk Potential (ARP). HOR terdiri dari dua tahap, yaitu HOR fase 1 yang berfokus pada identifikasi dan penilaian risiko, serta HOR fase 2 yang berfokus pada penentuan aksi mitigasi. Selanjutnya, metode RCA digunakan untuk mengidentifikasi akar penyebab dari risiko dominan. Hasil penelitian menunjukkan bahwa terdapat 18 risk agent yang teridentifikasi, dengan 10 risk agent dominan sebagai prioritas utama berdasarkan diagram Pareto yang berkontribusi terhadap 79,70% total risiko kerusakan mesin. Agen risiko prioritas utama adalah "Program preventive maintenance dan cleaning belum terjadwal sistematis" dengan nilai ARP sebesar 1113. Strategi mitigasi yang diusulkan diharapkan mampu meningkatkan efisiensi operasional dan output produksi secara signifikan. Dengan demikian, penerapan metode House of Risk (HOR) dan Root Cause Analysis (RCA) dapat menjadi pendekatan yang efektif dalam mengelola risiko kerusakan mesin serta meningkatkan kinerja operasional perusahaan. Kata Kunci: Manajemen Risiko, House of Risk, Root Cause Analysis, Circular Knitting, Mitigasi Risiko ABSTRACT PT MNJ is a manufacturing company operating in the textile industry, specifically focusing on production processes using circular knitting machines. In its operational activities, the company frequently faces issues regarding high machine breakdown frequency, which leads to increased downtime and decreased production output. This condition indicates that the company lacks a structured risk management system to identify, analyze, and mitigate risks associated with production machinery. This study aims to identify and analyze the risks of circular knitting machine breakdowns and determine appropriate mitigation strategies to minimize risk impact. The methods employed are House of Risk (HOR) and Root Cause Analysis (RCA). The HOR method is used to identify risk events and risk agents, as well as to determine risk priorities based on the Aggregate Risk Potential (ARP) value. The HOR framework consists of two phases: Phase 1, which focuses on risk identification and assessment, and Phase 2, which focuses on determining mitigation actions. Furthermore, the RCA method is used to identify the root causes of dominant risks. The research results show that there are 18 identified risk agents, with 10 dominant risk agents prioritized based on the Pareto diagram, which contribute to 79.70% of the total machine breakdown risk. The primary risk agent is "Preventive maintenance and cleaning programs are not systematically scheduled," with an ARP value of 1113. The proposed mitigation strategies are expected to significantly improve operational efficiency and production output. Thus, the application of House of Risk (HOR) and Root Cause Analysis (RCA) provides an effective approach for managing machine breakdown risks and enhancing the company's operational performance.
