Abstract
Telah dilakukan penelitian untuk mendeteksi bahaya pada unit
sulfur handling pabrik III PT. Petrokimia Gresik dimana pada sulfur
handling terjadi proses pencairan sulfur padat. Sulfur cair memiliki
bahaya seperti mudah terbakar dan dapat beracun, oleh karena itu
diperlukan adanya analisis bahaya. Analisis bahaya dalam penelitian
ini dilakukan menggunakan analisis HAZOP. Node yang dipakai adalah
melter dan storage tank yang merupakan komponen utama penyusun
sulfur handling. Guide word dan deviasi ditentukan berdasarkan
control chart yang dibentuk oleh data proses masing-masing komponen
selama bulan November 2014. Estimasi likelihood dilakukan
berdasarkan data maintenance PT. Petrokimia Gresik selama 5 tahun,
sedangkan estimasi consequences dilakukan secara kualitatif
berdasarkan kriteria risiko yang ditimbulkan. Hasil perkalian likelihood
dan consequences dengan risk matrix menghasilkan kriteria risiko dari
komponen. Berdasarkan hasil analisis, diperoleh hasil bahwa
komponen yang memiliki risiko bahaya paling besar adalah
temperature indicator storage tank dengan risiko bernilai extreme pada
deviasi high temperature dengan kategori consequences yang
menyebabkan kebakaran dan berakibat pada penurunan rate dan
kualitas produksi kemudian kriteria likelihood bernilai 3 dimana
kegagalan dapat terjadi lebih dari tiga kali dalam kurun waktu lima
tahun. Untuk menurunkan risiko, maka dilakukan perawatan dan
kalibrasi secara rutin, serta penambahan safeguard.

This study has been done to detect hazard from sulphur handling
unit where its function is to melt solid sulfur. Liquid sulfur has hazards
such as flammable and can be toxic, therefore it is necessary to analyze
the hazard. Hazard analysis in this study was conducted using HAZOP
analysis. Nodes used in this study are melter and storage tanks which is
the main component constituent for sulfur handling. Guideword and
deviation is determined based on the control chart which is formed by
the data of the respective components during November 2014. The
estimated likelihood be based on data maintenance PT. Petrokimia
Gresik for 5 years, while the estimated Consequences conducted
qualitatively based on the criteria of the risk posed. The result of
multiplying the likelihood and Consequences with risk matrix
generating risk criteria of the component. Based on the analysis, the
result that the component that has greatest hazard is storage tank
temperature indicator with extreme-value risk with high temperature
deviation, consequences criteria that can lead to fire, and likelihood
criteria C where the equipment failure may occur more than three times
within a period of five years. To lower the risk, it is necessary to
maintenance and calibration of the instrument on a regular basis, as
well as adding additional safeguards.
