Abstract

Melalui proses pemanasan, boiler mengubah air menjadi uap. Proses tersebut tentu mempunyai potensi bahaya. Salah satu faktor penyebab terjadinya bahaya adalah faktor manusia dan kegagalan instrumen. Analisis ini dilakukan pada faktor manusia terhadap kegagalan instrumen. Dengan menggunakan data maintenance instrumen dan observasi pekerja melalui kuesioner, maka didapatkan Mean Time To Failure (MTTF), laju kegagalan, serta Probability Failure on Demand (PFD) setiap instrumen. Metode regresi digunakan untuk menentukan hubungan kedua variabel tersebut, yaitu faktor manusia dan kegagalan instrumen yang diwakili oleh nilai PFD. Dari hasil perhitungan, didapatkan bahwa kegagalan instrumen dipengaruhi oleh faktor internal dan faktor eksternal manusia. Untuk faktor internal diantaranya adalah kepercayaan diri, perhatian, kemampuan, penyelesaian masalah, bekerja di bawah tekanan, kelalaian, dan stres pekerjaan menumpuk. Dan faktor eksternal yaitu informasi maupun standar yang diberikan oleh perusahaan (procedures), pendidikan dan pelatihan, komunikasi, waktu, serta evaluasi terhadap kegagalan instrumen di boiler PT. Pertamina (Persero) Unit Pengolahan IV Cilacap. Besar pengaruh (penyimpangan) faktor manusia terhadap kegagalan instrumen dapat ditunjukan melalui nilai U. Faktor yang paling berpengaruh dari manusia terhadap kegagalan instrumen pada boiler di PT. Pertamina (Persero) Unit Pengolahan IV Cilacap adalah task load stress yang mempunyai nilai U paling kecil di antara faktor yang lainnya yaitu sebesar 0,0866. Hal ini selaras dengan faktor internal yang mempunyai nilai U yang lebih kecil dari pada faktor eksternal yaitu sebesar 0,0953. ================================================================================================ Through the heating process, boiler converts water into steam. The process certainly has the potential dangers. One of factors contributing to the danger is the human factor and instrument failure. The analysis was performed on the human factor to the instrument failure. By using the maintenance data of instrument and observation workers through the questionnaire, the Mean Time To Failure (MTTF), the failure ratee, and Probability Failure on Demand (PFD) of each instrument are obtained. Regression method used to determine the relationship between the two variables, namely the human factor and the instrument failure which represented by the PFD value. From the calculation, it was found that the instrument failure is influenced by internal factors and external factors of human. For internal factors include selfconfidence, attention, skill, problem solving, working under pressure, omission, and the task load stress. And external factors include the information that is provided by the company's standards (procedures), education and training, communication, time, as well as an evaluation of instrument failures in boiler PT. Pertamina (Persero) Refinery Unit IV Cilacap. Large effect (deviation) of the human factor to the instrument failure can be indicated by the value of U. The most influential factor of human to the instrument failure in the boiler at PT. Pertamina (Persero) Refinery Unit IV Cilacap is the task load of stress that has the smallest value of U among other factors is equal to 0.0866. This is consistent with the internal factors that have a U value that is smaller than the external factor is equal to 0.0953.
