Abstract

Increasing the need for pure hydrogen in the industry is growing. One of its roles is in purification of petroleum industry. High purity hydrogen (99.99%) was obtained from methane using the steam methane reforming method in the hydrogen plant unit. Hydrogen is a very dangerous chemical element with its flammable properties. This research is conducted especially on purification system. Quantitative analysis is used to determine the frequency of hydrogen leakage, consequence modeling, and risk estimation that will be generated. The results of the analysis show that the highest frequency occurs in unignited release events. The jet fire scenario produces the longest fire length in the HPU about 27 meters. The jet fire scenario impact produces the farthest secure distance in the case of a leak in the HPU section of 60 meters. The flash fire produces the farthest distance loss in a leakage case in the HPU of 80 meters, and explosion at a radius of 200 meters will have a blast overpressure 7.62 psig with 22% fatality estimation of the population.

Abstract

Noise and heat has become a problem for worker in animal food processing company.  The aim of this study was to investigate the influence of noise and heat to stres. Noise and heat data were collected as primary data and stres was collected by questionnaire and analyzed by multiple regression. The result showed relationship between noise, heat and stres (sig 0,003<0.05). A moderate correlation between noise, heat and stres was also observed (r=0,561). No differences between two groups of age, gender and status were found with t test. Reducing noise and heat by engineering and administrative control were necessary execute. There is no need for different treatment to reduce stres between group of gender, age and status.

The result showed a relationship between noise, heat, and stress (sig 0,003<0,05). A moderate correlation between noise, heat, and stress was also observed (r=0,561). No differences between the two groups of age, gender, and status were found with t-test. Reducing noise and heat were necessary to be executed through engineering and administrative control. There was no need to differ the treatment to control the stress between a group of gender, age, and status.
