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.

Die Reduzierung der Unfallzahlen und berufsbedingten Erkrankungen, die Stärkung des Arbeits- und Gesundheitsschutzes genießen in Sachsen einen hohen Stellenwert, da sichere und gesundheitsgerechte Arbeitsbedingungen in den Schulen auch zur nachhaltigen Entwicklung des Freistaates beitragen. Um diesen Anspruch in den sächsischen Schulen dauerhaft zu sichern, entwickelt die Professur Arbeitswissenschaft und Innovationsmanagement der Technischen Universität Chemnitz das Arbeitsschutzmanagementsystem Schule »AManSys«. Einen wichtigen Teil der Systementwicklung bildet dabei das Handbuch zum »AManSys«, eine Handlungsanleitung und zukünftig digitales Hilfsmittel für den Schulleiter, um die Durchführung und Dokumentation der Prozesse in der Organisation im Arbeits- und Gesundheitsschutz regelkonform zu managen und damit seiner Unternehmerverantwortung gerecht zu werden.:1 Das Arbeitssystem Schule 1.1 Rechtliche Einordnung 1.2 Regelungen im Arbeitsschutz- und Unfallversicherungsrecht 1.3 Arbeits- und Gesundheitsschutz im Freistaat Sachsen 2 Chronologische Entwicklung von Arbeitsschutzmanagementsystemen 3 Entwicklung des »AManSys« aus dem OHRIS-Konzept 4 Entwicklungsstand »AManSys« 5 Literatur

New automated vehicles have the chance of high improvements to road safety. Nevertheless, from today's perspective, accidents will always be a part of future mobility. Following the “Vision Zero”, this thesis proposes the quantification of the driving situation's criticality as the basis to intervene by newly integrated safety systems. In the example application of trajectory planning, a continuous, real-time, risk-based criticality measure is used to consider uncertainties by collision probabilities as well as technical accident severities. As result, a smooth transition between preventative driving, collision avoidance, and collision mitigation including impact point localization is enabled and shown in fleet data analyses, simulations, and real test drives. The feasibility in automated driving is shown with currently available test equipment on the testing ground. Systematic analyses show an improvement of 20-30 % technical accident severity with respect to the underlying scenarios. That means up to one-third less injury probability for the vehicle occupants. In conclusion, predicting the risk preventively has a high chance to increase the road safety and thus to take the “Vision Zero” one step further.:Abstract Acknowledgements Contents Nomenclature 1.1 Background 1.2 Problem statement and research question 1.3 Contribution 2 Fundamentals and relatedWork 2.1 Integral safety 2.1.1 Integral applications 2.1.2 Accident Severity 2.1.2.1 Severity measures 2.1.2.2 Severity data bases 2.1.2.3 Severity estimation 2.1.3 Risk assessment in the driving process 2.1.3.1 Uncertainty consideration 2.1.3.2 Risk as a measure 2.1.3.3 Criticality measures in automated driving functions 2.2 Operational motion planning 2.2.1 Performance of a driving function 2.2.1.1 Terms related to scenarios 2.2.1.2 Evaluation and approval of an automated driving function 2.2.2 Driving function architecture 2.2.2.1 Architecture 2.2.2.2 Planner 2.2.2.3 Reference planner 2.2.3 Ethical issues 3 Risk assessment 3.1 Environment model 3.2 Risk as expected value 3.3 Collision probability and most probable collision configuration 4 Accident severity prediction 4.1 Mathematical preliminaries 4.1.1 Methodical approach 4.1.2 Output definition for pedestrian collisions 4.1.3 Output definition for vehicle collisions 4.2 Prediction models 4.2.1 Eccentric impact model 4.2.2 Centric impact model 4.2.3 Multi-body system 4.2.4 Feedforward neural network 4.2.5 Random forest regression 4.3 Parameterisation 4.3.1 Reference database 4.3.2 Training strategy 4.3.3 Model evaluation 5 Risk based motion planning 5.1 Ego vehicle dynamic 5.2 Reward function 5.3 Tuning of the driving function 5.3.1 Tuning strategy 5.3.2 Tuning scenarios 5.3.3 Tuning results 6 Evaluation of the risk based driving function 6.1 Evaluation strategy 6.2 Evaluation scenarios 6.3 Test setup and simulation environment 6.4 Subsequent risk assessment of fleet data 6.4.1 GIDAS accident database 6.4.2 Fleet data Hamburg 6.5 Uncertainty-adaptive driving 6.6 Mitigation application 6.6.1 Real test drives on proving ground 6.6.2 Driving performance in simulation 7 Conclusion and Prospects References List of Tables List of Figures A Extension to the tuning process
