Safety culture and safety climate consist of three layers covered in the organizational culture model from Shein (1992). A lower accident rate consistently has a higher maturity level than a high accident rate. Lack of knowledge and concern for operational supervisors and co-workers resulted in many accidents in the X Coal Mining Industry. This research aims to evaluate the existing maturity level conditions and accident data in the Coal Mining Industry X, identify safety culture variables based on departments and management levels, identify and analyze safety climate dimensions based on respondent characteristic factors, evaluate and provide recommendations for improving organizational culture in the Coal Mining Industry X. This research uses a mixed method with questionnaires, interviews, observations, and document analysis to improve the safety management system and reduce unsafe acts. The variables used to improve the safety management system are information, organizational learning, involvement, communication, and commitment, with internal factors in the form of demographics for high-risk workers and safety experts, namely department, age, length of work, last education, and management level. Meanwhile, the variables used to reduce unsafe acts are workers' perceptions of the management system and their coworkers with internal factors in the form of demographics for high-risk workers, namely department, age, length of work, and latest education. Validity and reliability tests were carried out before distributing the questionnaire. The safety culture questionnaire uses the Filho framework with 18 questions. It is divided into five dimensions, measured on 66 workers for safety climate, measured using NOSACQ-50 with a total of 50 questions, and divided into seven variables measured on 65 high-risk workers. The results of the questionnaire on safety culture will be analyzed using percentages and averages to determine the level in the company. The choice of conditions in the safety culture questionnaire is used in interviews to strengthen and support the survey results. The results of the questionnaire on safety climate will be analyzed using IBM SPSS Ver 24 to see the average, Kruskal Wallis test, and Mann Whitney test. Based on the results of the existing conditions in the X Coal Mining Industry, it shows a moderate level with a result of 42% and unsafe acts and unsafe conditions accidents occur almost every month with many incidents. Safety culture in the Coal Mining Industry The highest mean dimension value is in the organizational learning dimension, and the lowest is in the communication dimension. In the safety climate of high-risk workers, there are significant differences in the characteristics of respondents' length of work and latest education in the variables of safety communication, learning, and trust in the safety competence of co-workers, as well as the characteristics of respondents' latest education in strengthening safety management. The length of work and education factors influence the improvement of the safety management system and determine workers' unsafe behavior at work. Organizational culture can assess the maturity level in the X Coal Mining Industry by identifying risks and management as well as supporting the improvement of internal controls and processes. The recommendations include creating a program for workers by providing training, competency, teamwork, awareness, communication, and trust to improve the safety management system and behave safely in the Coal Mining Industry X
