Most of mining operations in Indonesia use open pit mine methods, with truck and shovel system and a large amount of manpower. The mining industry plays an important role contributed to the national economy and development in Indonesia, otherwise the mine accidents become as sensitive issue or problem. The main cause of mine accidents is still dominant of the low safety awarenesses and accountabilities, and also improperly cost spent on the occupational health and safety (OSH) programs. This thesis describes the concept behind the return on prevention and workers‟ perception descriptive analyses of the occupational health and safety in relation to improve safety performances. The proactive action plan related to accidents prevention is as an essential step of the risk management processes. Participation and intervention for all employees are important and urgent, especially for the frontline workers, which are crucial in achieving good safety performances with financial support properly. The main objective of this study evaluates of the workers‟ perception and cost spent on the occupational health and safety program at the companies in relation to accident prevention efforts. In general, the several objectives are described to evaluate of the mine accident rates, the validity and reliability tests of the questionnaires, workers relationships and suggestions, interviews, observations, and the OSH cost effectiveness. The methods of this study are assessed by the descriptive statistical analysis approaches of the return on prevention with the microeconomic model of the net present value, internal rate of return, and cost benefit analysis to justify the benefits return and the break even point and interventions directly according to the workers‟ perception through questionnaire, interview, and observation. The methodology is assessed by the gathering data obtained from the companies through the surveys of the questionnaire, interview, observation, and the money expenses in the occupational health and safety for the workers. The valuation methods are used by the degree of significance of 95%, margin of error 5%, with total number of respondents are 1,600 persons as sampling which representation of the four surface coal mine companies in Indonesia. The seven elements are a basic assessment approached of the training and education, personal protective equipment, preventive medical check up, employment injury insurance, improvement existing technology, signalization, and organization. The result shows the advantages using these analyses which described the importance of the money invested on OSH and effectiveness of interventions by worker‟s perception in order to prevent accidents at workplace. The effectiveness of interventions to the environment working conditions and workers mindsets directly. The OSH cost invested for workers, in general, will triggers the work performances to be better, and then the occupational health and safety in a strong position to achieve the goals of the company. Improvement safety awareness and accountability of workers shall reduce or prevent accidents at work, and the company should be invested money in the OSH program with the minimum amount is US $ 207.17 per employee or US $ 0.12 per ton of coal produced. The investment of the people and money properly shall give significant impacts in preventing accidents to achieve zero accident vision in order to protect people, property, process and profit of the company for short or long term benefits, and will also give a good images for sustainable in mining business.
