Abstract

Kegiatan magang mandiri di PT SUCOFINDO Cabang Surabaya dilaksanakan untuk mengaplikasikan ilmu teknologi rekayasa kimia industri dalam sektor pengujian, inspeksi, dan sertifikasi. Tugas khusus dalam pelaksanaan magang ini difokuskan pada analisis keselamatan dan kesehatan kerja (K3) melalui penilaian risiko operasional fasilitas industri. Berdasarkan analisis pembobotan potensi bahaya, Departemen Hot Annealing Pickling Line (HAPL) diidentifikasi memiliki tingkat kontribusi bahaya tertinggi sebesar 48,12% yang termasuk dalam kategori Prioritas I (Sangat Tinggi). Untuk memitigasi risiko tersebut, dilakukan pemodelan simulasi worst-case scenario menggunakan perangkat lunak ALOHA (Areal Locations of Hazardous Atmospheres) guna menganalisis dispersi gas beracun Hydrogen Fluoride (HF). Hasil simulasi ALOHA menunjukkan bahwa zona ancaman fatal (AEGL-3) mencapai radius 1.026 yard (sekitar 1 km) ke arah timur laut, yang memerlukan prosedur evakuasi ketat dan deteksi dini. Selain kajian lingkungan kerja, dilakukan pula evaluasi keteknikan pada proses produksi Ferronickel. Evaluasi ini mencakup penyusunan neraca massa dan neraca energi pada unit Rotary Kiln, serta pelaksanaan Hazard and Operability Study (HAZOP) pada unit Rotary Dryer. Kajian HAZOP mengidentifikasi sejumlah deviasi krusial terkait suhu dan laju alir, serta merumuskan rekomendasi perbaikan instrumen pengendalian untuk menjaga agar operasi tetap berada pada batas aman (ALARP). Melalui pelaksanaan magang ini, rekomendasi komprehensif diberikan untuk pembaruan Dokumen Pengendalian Potensi Bahaya Besar, optimasi sistem pengaman, dan kesiapsiagaan medis untuk meminimalkan dampak kecelakaan kerja.

The independent internship program at PT SUCOFINDO’s Surabaya Branch was conducted to apply knowledge of industrial chemical engineering technology in the testing, inspection, and certification sectors. Specific tasks during this internship focused on occupational safety and health (OSH) analysis through the assessment of operational risks at industrial facilities. Based on a weighted analysis of potential hazards, the Hot Annealing Pickling Line (HAPL) Department was identified as having the highest hazard contribution rate at 48.12%, which falls under Priority I (Very High). To mitigate these risks, a worst-case scenario simulation was conducted using ALOHA (Areal Locations of Hazardous Atmospheres) software to analyze the dispersion of the toxic gas hydrogen fluoride (HF). The ALOHA simulation results show that the fatal hazard zone (AEGL-3) extends to a radius of 1,026 yards (approximately 1 km) to the northeast, requiring strict evacuation procedures and early detection. In addition to the workplace environmental assessment, an engineering evaluation of the ferronickel production process was also conducted. This evaluation included the preparation of mass and energy balances for the Rotary Kiln unit, as well as the implementation of a Hazard and Operability Study (HAZOP) for the Rotary Dryer unit. The HAZOP study identified several critical deviations related to temperature and flow rate, and formulated recommendations for improving control instruments to ensure operations remain within safe limits (ALARP). Through this internship, comprehensive recommendations were provided for updating the Major Hazard Control Document, optimizing safety systems, and enhancing medical preparedness to minimize the impact of workplace accidents.
