Background: VO2 max measurement method for physical fitness test using QCST method has been widely used. VO2 max measurement is important for workers to determine the appropriate loading. There are several factors related to a person's ability to carry out physical fitness tests, including body posture, pulse, BMI, gender. Purpose: analyze factors related to the ability to conduct tests with the QCST method. Method: This research was analytic observational type which was conducted cross-sectional on 46 respondents taken randomly on 48 third-year D3K3 students in the Faculty of Vocational Studies of Universitas Airlangga. The independent variable consisted of gender, resting pulse rate and BMI. Dependent variable is the ability to complete the QCST test for 3 minutes. The relationship between variables was tested using the Fischer and Chi-square test with a significance of 5%. Results: The results showed that most respondents were unable to complete the QCST test for 3 minutes. There is no relationship between the ability to perform the QCST test with gender (p=0,365); resting pulse (p = 0,351) and BMI (p =0,187). Conclusion: QCST test for 3 minutes is too heavy for respondents. It is necessary to modify the QCST test that is appropriate for Indonesians.

The presence of Globally Harmonized System (GHS) in the world can not be separated from the element of risk and danger of the chemicals which are used both for humans and for the environment. PT. Petrokimia Gresik is one of companies which use a wide various of hazardous chemical elements. In the process of production and the products themselves, as found in Production Process Urea Unit. PT Petrokimia Gresik start to implement GHS in 2009 based on the regulations of the Minister of Industry No. 87/M-IND/PER/9/2009 about Globally Harmonized System of Classification and Labels On Chemicals. This study aimed to Evaluate of the implementation of the GHS as an illustration of condition of GHS application on PT. Petrokimia Gresik factory 1 unit urea. This research is descriptive study. Subjects in this study is a variety of work related to the implementation of the GHS in the urea unit and the object of this research is the implementation of the GHS. This study variables include the application of GHS such as dangers, and SDS / LDK. The results of the study showed that the GHS of PT Petrokimia Gresik had been adequately implemented (66%), because it only fulfills 2 variables from 3 variables tested. Keywords: evaluate, globally harmonized system, illustration

Background : Safety behaviour is an act worker to minimize the possibility of accidents in workplace. Based on the Antecedents-Behaviour-Consequence (ABC) theory, safety behaviour of worker related with the antecedent and consequence factors. Purpose : The purpose of this research was to study the association between antecedent and consequence factors with safety behaviour of workers in Ring Frame Unit Spinning II PT. X. Methods : This was an observational descriptive research with cross sectional approach. Sample size was the total population 24 workers. The variables studied were level of knowledge, motivation, perception, private problem, OSH regulation, availability of safety facilities, frequency of OSH training, controlling, positive reinforcement (reward), and negative reinforcement (punishment). The strength of relationship between variables dependent and independent were analyzed by using Contingency Coefficient (C). Results : The results showed that there were strong association between motivation, private problem, frequency of OSH training, positive reinforcement (reward), and negative reinforcement (punishment) with safety behaviour (C = 0.622, C = 0.508, C = 0.702, C = 0.669, dan C = 0.707, respectively). There were very strong association between knowledge, perception, OSH regulation, and controlling with safety behaviour (C = 0.763, C = 0.797, C = 0.768, dan C = 0.797, respectively). Conclusion : the higher the knowledge and motivation to work safely the higher the safety behaviour of the workers would be. Workers who have not personal problem, have already participated in OSH training, feeling supervised and given reward and punishment applied higher safety behaviour.

Background : Noise was one of the dangerous factors at a workplace which causes various effects on workers. Purpose :  The purpose of this research was to described the activity stages, identified the noise danger, and assessed the risk and its level at Air Separation Plant of PT. X. Methods : This research was a descriptive research with a cross sectional approach. The object of the research was the noise danger potential and the noise risk level assessment at Air Separation Plant of PT. X. Results : The result of this research showed that there were 12 identified noise danger points. These results consisted of 5 (42 %) noise risks with low category, 2 (16 %) with middle category, and another 5 (42 %) with high category. The highest noise intensity measurement result was found on Recycle Nitrogen Compressor (RNC) machine, which was 116,5 dBA.  Conclusion :  Based on this data, it can be concluded that there were 12 identified noise danger points and the highest noise intensity measurement result was found on Recycle Nitrogen Compressor (RNC) machine, which was 116,5 dBA. It is suggested for the related company to execute controls mostly in diminishing the noise sources.

Background : High absenteeism rate affect productivity.In turn, low productivity makes the company suffer loss. In Indonesia there are rarely researches on the issue although actually it needs much attention. Purpose :  The aim of this research was to analyze the correlation between individual factors with   absenteeism  among workers of Ring Frame (Spinning I)PT. X in 2013. Methods : This was an observational descriptives research with cross sectional approach of absenteeism during 2013. The population were workers who experienced absent in 2013 (43 peoples). The variables were individual factor (age,sex, workers status,married status,work span, and education level) and the absenteeism rate such as GAR (Gross Absence Rate),ASR (Absence Severity Rate), AFR (Absence Frequency Rate), Day lost, Spells and the control measures. Results : The results showedthat the days lost were 130 days/years, with frequency absenteeism of 85 spells. The absenteeism rate were : GAR 0,3 % ; ASR 1,1 days and AFR 0,65 spells.GAR, ASR, and AFR were in the normal limit, the highest rate of day lost in category < 3 days and the highest rate of spells in category 1-2 spells. The highest rate of case group found in : age group 25-35 years, women, persistent workers, married, has a work span of 5-14 years and the education level in senior high school.  Conclusion :  there were no significant correlation between individual factors and absenteeism.
