INFLUENCE OF OCCUPATIONAL HEALTH SAFETY (OHS) CULTURE, COMMITMENT MANAGEMENT, OHS TRAINING ON OHS PERFORMANCE IN OIL & GAS CONTRACTORS COMPANY IN BATAM ISLAND

Indonesia has very promising oil and gas potential to be exploited, including in Riau Islands province, which has 15 oil and gas companies operating, and 4 of them are already in production. Batam Island is part of the Kepulauan Riau province, and there are oil and gas fabrications in it that are exported out from Batam Island. This fabrication is closely related to occupational safety and health. This study was obtained from 261 employees who work in the fabrication company or oil and gas contractor. Data were processed using Statistical Package for Social Science (SPSS) version 24. The research of this method used non-probability sampling, where sampling techniques do not provide equal opportunities for each member of the population to be selected as a sample. This study illustrated that OHS culture and management commitment significantly positively affect occupational health safety performance, but OHS training does not have a significant effect.

The statement from Minister of Manpower of the Republic of Indonesia in daily tempo.com, dated January 12, 2020, said: "Today, innovation, automation, supercomputers, artificial intelligence and flexibility in work patterns have brought economic changes to the digital-based. With the industrial revolution 4.0 based on information technology, do not let OHS problems have pay attention when the victims fall when victims fall, or accidents happen. Do not let us care about OHS when there is a lawsuit from the community or the families of the victims "(Ida Fauziah, Minister of Manpower of the Republic of Indonesia, 2020. Tempo.com). As we know, there have been 157,313 work accident cases in 2018, and from January to September 2019, there have been 130,923 cases, which shows that there has been a decrease in work accident cases by 26. 40% Ananda (, 2020). Of course, reducing work accidents is a significant concern that we must do in preventing work accidents from ensuring the employees can work safely.

Literature Review Occupational Health Safety Culture
In the fabrication and exploration of the oil and gas industry, the safety culture or OHS culture plays an important role. Oil and gas workers realize that what is no less important is the availability of place and time to communicate about OHS issues (Hong et al., 2018). Communication is part of a safety culture; when a work accident occurs, communication is needed. Communication can prevent workplace accidents; as mentioned in several previous studies, communication from safety culture is essential because it can increase KPI (Key Performance Indicator) and the opposite.
Culture is a habit that is a fundamental way of thinking where group studies and uses it to solve problems with external and internal approaches that are strong and helpful so that people in a group accept it and feel there is a relationship to problems which are solved by that habit (Schein, 2010;Helen Lingard et al. (2017). OHS culture is a habit that thinks safety at work is the main thing. Work shall be done with good habits such as not being willing to work before the OHS meeting first or known as toolbox talk safety meeting.

Management Commitment
Management commitment is the foundation of an effective safety management system (Latief et al., 2017). Previous studies have described that one of the factors affecting occupational safety and health is the management commitment from a company. Top management's policies will be very easily understood by subordinates and carried out because there is a commitment from the management to obey them, and work accidents can be avoided in the workplace. Based on daily activities, commitment, awareness, communication, and supervision from top management are management commitment scope (Sarkam et al., 2018).
Previous research using management commitment variables affects OHS performance in terms of safety compliance and safety participation (Hong et al., (2018). This research shows that the management committed to OHS shall make every effort through internal control, resources, and practice it then the employees feel it. According to Khdair (2011), this variable states that leadership as part of management commitment has a positive effect on OHS performance. Another researcher, Chen et al., (2018), explained that management commitment needs a development time frame and that differences in concepts, beliefs, and values affect OHS performance effectively. Another researcher, Sarkam et al. (2018), explained a significant positive relationship between OHS performance and management commitment. This variable is also used by Romuty (2017) with the results of research which explains that safety leadership as part of management commitment, Chong (2018) has a significant positive effect on the OHS performance variables.

Occupational Health Safety Training
OHS training is an essential element of an OHS management system; the training is conducted to increase the awareness of potential hazards and risks (Chong, 2018). OHS training is also a branch of psychology called educational psychology, where the learning and education process is studied (McGraw, 1953). A person who works in the oil and gas world can only reduce work accidents by fulfilling the OHS requirements by attending various safety training. Workers who are attending the training will have more knowledge on OHS and proficiency in preventing workplace accidents. According to Law No. 1, the year 1970 concerning Occupational Safety and Health, companies must provide instructions, training, and supervision necessary to ensure the safety and health of workers/ laborers.
The OHS training will affect OHS performance in oil and gas fabrication, as seen from the key performance indicator (KPI) written in company statistics. Workers in oil and gas fabrication can identify hazards, assess risks and determine controls because the workers have been trained. Participation in OHS (safety participation) through training obtained in the OHS training program within the company and this implementation is carried out before undertaking an oil and gas project. OHS analysis is known as the Job Safety Analysis (JSA), aims to reduce workplace accidents. Workers doing work already know the dangers of the work and are carried out safely because of JSA. This affects OHS performance by reducing the number of work accidents. Conduct safety training in the workplace and comply with OHS requirements (safety compliance) and labor laws.

Conceptual Framework
Based on the explanation above, the conceptual framework proposes as below figure 1 to show the OHS performance as below : The hypothesis is a temporary answer to the formulation of the research problem, where the formulation of the research problem has been stated in the form of a question sentence. In this study, there are three hypotheses proposed, and the truth is still to be tested. Based on the research model described above, the following hypothesis is formulated: H1: OHS Culture has a significant effect on OHS Performance. H2: Management commitment has a significant effect on OHS Performance. H3: OHS training has a significant effect on OHS Performance.

Research Method
The population in this study were employees who worked at oil and gas companies in Batam Island, both onshore and offshore. The fabrication company or oil and gas contractor, such as PT. McDermott Indonesia, PT. Citra Tubindo Engineering, PT. Dwi Sumber Arca Waja (DSAW) and several oil and gas fabrication companies onshore and offshore in Batam Island with 261 respondents.
The questionnaire consists of 28 statements containing descriptive statistical values using a scale of 1 to 5, and the data will be analyzed using SPSS version 24.
Determination of data sources in this study was carried out using non-probability sampling, which did not provide equal opportunities to members of the population to be selected as samples Sugiyono (, 2017). This sampling technique is carried out by purposive sampling method, which means that it is carried out with specific considerations; in this case, the researcher considers only people who work in the oil and gas industry with expertise in this industry are determined to be the source of the data.
OHS performance is the dependent variable in this study. OHS performance plays a significant role in determining a company's reputation or business because it is one of the critical performance indicators sold to prospective clients. Previous research has described occupational safety and health, which is predicted to affect OHS performance itself. OHS performance can also be likened to what is done by workers in the workplace, and this is included as part of safety compliance and safety participation (Gao et al., 2016).

Figure 2. P-P Plot Normality Test Results
Based on Figure 2 above, it is clear that the Normal P-P Plot chart dependent variable occupational health and safety performance provides information about the normal distribution. This is known by observing that the distribution data from bottom to top always follows a diagonal line. This description is evidence that the occupational health safety performance has a normal distribution.  The distribution data in figure 3 above shows the points spread randomly. There is no particular shape or pattern so that it can be concluded there is no heteroscedastic symptom or visually the assumption of homoscedasticity is fulfilled in that model.

Hypothesis Test
This research describes the hypothesis test results using multiple regressions, which consists of the results of the F test, the t-test results, and the coefficient of determination test results. The results of the F test can be explained in table 3 below: In table 3 above, the results of the F test obtained a probability level of 0.000. Based on this information with 0.000 <0.05, this research model can predict the dependent variable (occupational health safety performance). Another part of the hypothesis test results is the t-test, where each independent variable is used to see the level of significance of the affected variable. The results of the test can be seen in Table 4 below: The t-test results above show that the significance level of the relationship between OHS culture and occupational health safety performance is smaller than the value of 0.05 (0.000). The result concluded that there is a significant effect of safety culture on occupational health safety performance. The results of this study are consistent with previous studies conducted by Chen (Hong et al., 2018). Table 4 above shows that management commitment as an independent variable has a significant effect on occupational health safety performance. This is indicated with a value less than 0.05 (0.000). The results of this study are consistent with the results of previous studies, including Chong et al. (2018), Gao et al. (2016Christina et al. (2012);Singh et al. (2018), Khdair, Shamsudin, andSubramanim (2011);Sarkam Shaharuddin, Zaki, Maskdek (2018); Romuty, Chandra (1017); but inconsistent with Chen et al., (2018), Zina et al., (2016), Rafidah, et al. (2014. The data processing results in table 4 above show one of the independent variables has a value greater than 0.05 (0.000), with a value of 0.146. The independent variable is OHS training means the OHS training variable does not have a significant effect on occupational health safety performance. The results of this study are consistent with the results from previous research conducted by Subramaniam (2016).
The other result studies which state that OHS training does not affect OHS performance are Chen et., Al (2018); Chong et., Al (2018), but it is different with Alolah et al. (2014) which the result is inconsistent because, according to his research, OHS training affects OHS performance. Another researcher who said the OHS training affects OHS performance is Mash et., . According to this researcher, OHS training has a positive effect on OHS performance. Other researchers who explain that OHS affects OHS performance are Mash, Subramaniam, Johari (2016); Zina, Ramalub, Hassana (2016).
Observing the three independent variables above, it is clear the commitment management has the most outstanding contribution to improving the OHS performance with a value of 0.353 or 35.3%, followed by OHS culture with a value of 0.279 27.9%. The lowest value is the OHS training variable, with a value of 0.039 or 03.9%. Therefore, the standard coefficient can be concluded that every time there is an increase in the value per unit in commitment management, it will increase the work health safety performance by 0.613, each increase in the value per unit in the safety culture of 0.196 on the performance of occupational health safety. The safety training variable did not show an increase in occupational health safety performance in this study. Understanding of this process, the standard coefficient shows consistent results where management commitment has a significant influence, namely 0.613.
The coefficient of determination test is one part of the results of hypothesis testing, and the results of the coefficient of determination can be seen in the information in table 5 below. The results of the Adjusted R2 test below illustrated that the independent variable such as OHS culture, management commitment, and OHS training affected the dependent variable OHS performance of 64.1%. In comparison, the remaining 35.9% is influenced by other variables.

Conclusion
The results of this study were conducted based on the phenomena that occur in oil and gas fabrication companies related to the performance of occupational health and safety. The problem of occupational health and safety has been formulated, so the research aims to find out the answers to the problems of the factors that affect occupational health and safety in oil and gas fabrication companies in Batam Island. The results of this study can be concluded that commitment management and OHS culture have a significant positive effect. However, it is different with the independent variable OHS training does not significantly affect OHS performance. Researchers suggest that the following researchers focus on other variables that can affect OHS performance in oil and gas fabrication companies.
