Indonesia is one of the ten largest coal producing country in the world. Mining characteristics which complicated and surrounded with high technology make the risk of workplace accidents in mining industry unavoidable which occur due to many factors. The purpose of this study is to describe the immediate causes and basic causes of occupational accidents on surface coal mining activities in Mining Operation Division PT X in 2015. This study refers to Domino and Loss Causation Model theory. The design uses a mixed methods research. The quantitative data using secondary data from the accident investigation reports to get the accident causes distribution, then followed by a qualitative study which analyzing occupational accident causes of property damage and lost time injury incidents. The research tools use SCAT and in-depth interview. The results show that the most contributing factor as a direct cause are improper decision making, violation, and hazardous environmental conditions. While the basic causes include: inappropriate aggression, fatigue and inadequate identification of critical safe behaviors. Improvement behavior is now performed by operators by obey the work procedures. Supervisors will upgrade supervision intensively and management will do the refreshment of working procedures to prevent similar accidents happen again in the next day.

The safety performance of a company shows how well the company is in protecting employee safety and reducing losses due to work accidents (Sullivan, 2000). Safety performance in a company or organization is influenced by various factors, one of which is the human factor. In the loss causation model, (Bird & Germain, 1996) explains that there are five elements as factors that cause accidents, namely lack of control due to inadequate programs, program standards and compliance with standards, basic causes consisting of personal factors and work factors, causes direct actions consisting of non-standard acts and conditions, and the resulting harm to people, property and processes. PT. X is a Mining Service Company engaged in blasting. From the data of safety accidents that occurred at PT. X over the past 10 years, it was found that 60% of the main causes of these accidents were due to the human factor. The research in this thesis aims to determine the effect of human factors on the safety performance of PT.X and to analyze the most influential human factors in improving the safety performance of PT. X as measured by the level of work accidents. Based on the loss causation model and the basic causes of work accidents at PT. X period 2009-2013, there were six (6) human factors studied, namely competence, fitness to work, compliance with procedures, safety communication, safety awareness, and safety behavior. The result of the research is that competence and communication are the most influential human factors in improving the safety of PT. X.
Occupational accident cases in the cement industry, especially the packer area, are a serious problem that can have an impact on many things including productivity, safety, and worker welfare. Data shows that occupational accidents in the Packer area of the PT X Cement Industry in 2024 have increased compared to 2023, making it the area with the highest accident frequency in 2024. Occupational accident investigations and corrective actions have been conducted, but accidents continue to recur. This may be due to the absence of human factor analysis during the investigation process. Therefore, this study was conducted to determine contribution of human factors specifically latent conditions and active failures to occupational accidents that occurred in the PT X packer area during 2023-2024. This study was conducted using a descriptive analytical method using the Human Factor Analysis Classification System (HFACS) method. The results of the study showed that latent conditions contributed more to occupational accidents than active failures. The latent condition factors that contributed the most to occupational accidents included organizational climate, organizational process, resource management, and inadequate supervision. Meanwhile, the active failure factor that contributed the most was decision error. PT X needs to improve latent conditions at the organizational level and implement control to mitigate active failures in the packer area.
One of the main purpose of accident investigation is to create recommendations for corrective actions in order to prevent the recurrent accident in the future. Some reccurent accidents at PT.X indicating that the previous accident investigations have not done effectively. One of the main factors in accident investigation is the quality of investigators, because investigators conduct the whole steps of accident investigation. Based on an early interview with some of the investigators, they said that they‟ve never been trained about accident investigation. Thus, this qualitative study aims to assess the quality of accident investigators at PT.X. The aspects of quality that will be assessed in this study are competency, consistency, and the ability of investigators to be open minded. The method used in this study is descriptive qualitative with in-depth interviews, observations, and secondary data. The result showed that the overall quality of accident investigators at PT.X is categorized not good, in which the competency aspect is poor, consistency aspect is good, and the ability of investigators to be open minded aspect is good enough.

Karyawan musiman atau kontrak merupakan permasalahan dalam penerapan sistem manajemen di perusahaan. Sifatnya yang dipekerjakan dalam waktu tertentu dan merupakan pekerja kasual merupakan hambatan dalam penerapan SMK3, hal ini dibuktikan dengan kecelakaan kerja yang terjadi di perusahaan. Tesis ini mengembangkan penelitian terhadap investigasi kecelakaan untuk mencari faktor-faktor yang menyebabkan terjadinya kecelakaan pada karyawan musiman atau kontrak. Penelitian dilakukan untuk mencari kesalahan-kesalahan aktif maupun laten sehingga tindakan yang sistemik dapat ditentukan. Penelitian ini bersifat deskriptif analitik dengan. Hasil penelitian ini menyarankan tindakan perbaikan pada elemen-elemen sistem manajemen keselamatan dan kesehatan kerja untuk mengurangi atau menghilangkan kesalahan-kesalahan baik aktif maupun laten sehingga akan memperkuat ketahanan sistem terhadap terjadinya kecelakaan.
Temporary or contract worker has an issue on implementing safety management system in the company. The type of their employment with short term/temporary basis and as casual worker become a burdain on implementing safety management system, this shown on the safety accident that happened in the company. This Thesis developed a research on the incident investigation to find the factors of accident that caused an injury to the temporary or contract worker. The research is to identify active and latent failure, so the systemic improvement action plans could be developed. The research type is in depth analysis with descriptive qualitative as a result. The result of the research propose improvement on the safety management system elements to minimize or eliminate active or latent failure and so, develop strong defense to accident to.
