Abstract

Industri manufaktur komponen presisi dan alat bantu pengujian memiliki karakteristik proses yang menuntut akurasi tinggi, interaksi langsung antara operator dan mesin, serta kestabilan proses yang baik, sehingga berpotensi menimbulkan risiko kecelakaan kerja sekaligus penyimpangan kualitas proses dan hasil produksi. Penelitian ini bertujuan untuk mengidentifikasi potensi bahaya dan penyimpangan pelaksanaan kerja, menentukan tingkat risiko kecelakaan kerja serta potensi dampaknya terhadap kualitas proses dan hasil produksi, menganalisis variabilitas kinerja pada setiap fungsi kerja, menganalisis tingkat variasi nilai risiko berdasarkan penggabungan metode, serta menentukan prioritas perbaikan pada fungsi atau aktivitas kerja kritis. Metode yang digunakan dalam penelitian ini adalah penggabungan Failure Mode and Effect Analysis (FMEA), Functional Resonance Analysis Method (FRAM), Triangular Fuzzy Number (TFN), dan Monte Carlo Simulation (MCS). Hasil penelitian menunjukkan bahwa mesin bubut konvensional merupakan objek dengan tingkat risiko tertinggi, dengan total nilai Risk Priority Number (RPN) sebesar 1409. Pada analisis FRAM teridentifikasi 17 fungsi kerja dan 21 coupling pada proses pembubutan. Hasil simulasi pada 20 skenario operasional dengan 1000 iterasi menghasilkan nilai ambang global P90 sebesar 7,2 dan P95 sebesar 10,2. Coupling kritis yang paling dominan adalah F9→F12, F9→F13, dan F8→F11, yang menunjukkan bahwa aktivitas monitoring, penyesuaian proses, penggantian pahat, dan pengukuran sementara merupakan titik paling sensitif terhadap penyebaran variabilitas. Oleh karena itu, prioritas perbaikan difokuskan pada stabilisasi fungsi-fungsi kritis melalui penguatan monitoring proses, standar penggantian pahat, pengukuran yang lebih aman dan akurat, serta pemeriksaan kondisi mesin dan parameter kerja, sehingga dapat menurunkan risiko kecelakaan kerja sekaligus mendukung peningkatan kualitas proses dan hasil produksi

The precision component and testing tool manufacturing industry involves high-accuracy processes, direct interaction between operators and machines, and the need for stable production performance, creating the potential for occupational accidents as well as deviations in process quality and production results. This study aims to identify workplace hazards and deviations in work execution, determine the level of occupational accident risk and its potential impact on process and product quality, analyze performance variability in each work function, assess the variation in risk values through an integrated method, and determine improvement priorities for critical work functions or activities. The methods applied in this research were the combination of Failure Mode and Effect Analysis (FMEA), Functional Resonance Analysis Method (FRAM), Triangular Fuzzy Number (TFN), and Monte Carlo Simulation (MCS). The results showed that the conventional lathe was the object with the highest risk level, with a total Risk Priority Number (RPN) of 1409. The FRAM analysis identified 17 work functions and 21 couplings in the turning process. Simulation results for 20 operational scenarios with 1000 iterations produced global threshold values of P90 = 7.2 and P95 = 10.2. The most dominant critical couplings were F9→F12, F9→F13, and F8→F11, indicating that process monitoring, process adjustment, tool replacement, and in-process measurement were the most sensitive points for variability propagation. Therefore, improvement priorities should focus on stabilizing these critical functions through better process monitoring, clearer tool replacement standards, safer and more accurate measurement practices, and improved machine condition and parameter checks, in order to reduce occupational accident risk while supporting improvements in process quality and production results.
