This study aims to determine the relationship between heat stress index and fatigue that affects the risk of work accidents. This research is a quantitative research using the cross-sectional method. In this study, the sample consisted of all project staff, whose data was collected via a questionnaire, and the ambient temperature was measured for environmental thermal monitoring. The results of this study explain that there is a significant relationship between the heat stress index and the fatigue experienced by workers in cases of work accidents. The analysis found that fatigue was the most dominant variable because it had the highest odds ratio value of 72.8 (95% CI: 10.318 612.895). This shows that tired workers have more atterrated of experiencing work accidents than workers who are not tired after being controlled by the variables of air temperature, airflow humidity, workload, airflow, BMI, and sleeping time. In addition, worker factors such as a high BMI (obesity tendency) and a high pulse rate are the causes of the number of accident cases at the Project in 2021
PT. XY Dump Truck service company, a cement subsidiary in the limestone mining sector, at PT. XY has had a accident, so an accident analysis using the HFACS-MI method needs to be done. This research to analyze the factors that contribute laten and active failures to accidents in dump truck operations based on the HFACS-MI framework. This research uses a case study research design with a semi-quantitative method with a descriptive approach. The population in this study is accident report data in the form of investigation results from the operation of DT as many as 27 cases of work accidents in 2019-2021. The results showed that the category of HFACS-MI that contributed the most was organizational influences as many as 429 related to the lack of work safety analysis. Then followed by 370 Unsafe leadership related to inadequate work supervision. There are 289 preconditions for unsafe acts related to slippery road surface conditions. As many as 247 unsafe acts are related to failure to recognize hazards. And the smallest contributing category is the outside factor as much as 1 related to workshops outside the company. It is concluded that the HFACS-MI framework on latent failures that contributes a lot is organizational influences and on active failures that contributes a lot is unsafe act, then the suggestions for corrective actions in each HFACS-MI category are on repairing latent and active failures with an emphasis on the category of organizational influences.
Accident investigation is a systematic process in analyzing an accident based on data and facts collected through a thorough examination of the factors that contribute to the accident and cause of the accident. This research discusses the accident investigation system at PT. X compared with research, government regulations, and standards from several institutions such as OHSA, HSE Executive, ILO, and ILCI. A comparison is conducted by comparing the elements that exist in the accident investigation system at PT. X with the synthesis of elements to identify the plus and delta of the implemented system. The research is using the qualitative method and the analysis units used are procedures, training material, investigation reports, and interview results. The results showed that PT. X already has a management commitment to support the investigation process by providing procedures, human resources, facilities and infrastructure to support the investigation, training the investigation team, and appointing sponsors as representatives of the company's highest leadership to ensure that the investigation process is carried out appropriately. The following are several things that can be improved from the accident investigation such as providing an opportunity for the investigation team to be released from daily work, giving feedback to the RCA Facilitator 18 related to the analysis of causes, and the validation process is carried out consistently and recorded so it can be accounted for. The conclusion of this research is that PT. X has a good accident investigation system compared to the synthesis of elements. Implementation of the investigation system at PT. X has several plus and delta that can still be improved thus increasing the quality of the investigation.
The focus of this research is to analyze all occupational accidents of lifting activities on land rig operations in PT ‘X’ using the Human Factor Analysis and Classifications System (HFACS) method in 2014 - 2018. The type of research methodology is qualitative research with a descriptive design. The final result shows that the unsafe act layer is the most ineffective layer that contributing to almost all occupational accident cases which is 45 of 49 total cases of occupational accidents. Error is the sub-layer of unsafe act which has the highest number of contributions to occupational accident cases with total 39 cases. On the other side, the organizational influences layer is the second layer that has high contribution to accident which is 26 of 49 total cases of occupational accidents. The organizational process is the sub-layer of organizational influences which contributing to 23 cases of occupational accident. The third layer which has contribution to accident is unsafe supervision. The unsafe supervision has contribution to accident which is 16 of 49 total cases of occupational accidents. Inadequate supervision and planned inappropriate operation are the sub-layer of inadequate supervision which contribute to the accident cases for 10 cases equally. The layer of preconditions for unsafe actions is the effective layer which has contribution to occupational accident cases which is 8 of 49 total cases of occupational accidents. Personnel factor is the sub-layer of preconditions for unsafe actions which contribute to 7 cases of occupational accidents. According to the result, researcher recommend that corrective action must be taken at each layer of HFACS as the safety protection system, both latent failures and active failures with the emphasis on improvement, which start from the organizational influences layer, followed by the unsafe supervisions layer, and then unsafe actions layer, while the improvement on the layer of precondition for unsafe actions becomes the last improvement. Improvement to organizational influences layer, unsafe act layer, and unsafe supervisions layer will have a positive influence on the layer of precondition for unsafe actions.
Introduction: Workers are one of the vulnerable groups for drug abuse. Drugs use by workers can lead to loss of productivity, workplace accidents and injuries, the increase of employee absenteeism, the decrease in morale and health problems. The purpose of this study was to determine the demographic and psychosocial determinants of drug abuse among workers in Indonesia. Methods: This study was an analysis of secondary data from the 2017 National Survey on Drug Abuse in the Working Group with a total of 34,397 respondents. Data analysis was performed using logistic regression. Results: The multivariate test showed that drug abuse behavior among workers was related to demographic characteristics (education), psychological characteristics (the agreeable attitude towards drug abuse, smoking behavior, drinking behavior, risky sex behavior and doing high-risk/dangerous work), and social characteristics. (drug-prone home environment, easy access to drugs, family consuming drugs, coworkers consuming drugs, friends consuming drugs, conflict within the family, conflict with the co-workers, age at the first time working less than 15 years and rarely/never doing religious activities). Conclusion: Many factors influence drug abuse among workers, therefore there is a need for comprehensive efforts to encourage the creation of a drug abuse prevention programs for workers in Indonesia.
Safety climate is the shared perception of employees about policies, procedures and practices related to safety in their work environment. Safety climate is related to safe behavior and occupational accidents in the workplace. The purpose of this study was to measure the maturity level of the safety climate at PT X and to analyze its relationship with safety behavior. This research is descriptive quantitative using a questionnaire method with a total of 200 respondents. A structured questionnaire was used to capture the socio-demographic characteristics of the respondents, safety climate, and safety behavior. Respondents participated in this study by answering questionnaires distributed online and offline. The findings of this study indicate that the maturity level of the safety climate at PT X is at the fair level, there is a very strong relationship between the subdimensional variables and the safety climate, and a fairly strong relationship between the safety climate and safety behavior. The study emphasizes that an increase in the level of safety climate can increase safe behavior therefore it is effective in reducing the incidence of work accidents.
