Abstract

The occupational safety and health (K3) conditions of companies in Indonesia are estimated to be quite low, this can be seen from the high risk of accidents that can occur in a company. Work accidents occur due to workers, work tools and the work environment, so it is necessary to implement occupational safety and health (K3) in carrying out mining activities. Safety and health factors are very important because they have a big influence on employees, society and also company assets. The aim of this research is to look at the implementation of Occupational Health and Safety in coal transportation at PT Lematang Coal Lestari. The method used in this research was field observation in the form of visits and direct field observations as well as data collection in the form of interviews or surveys. The research results showed that from the 8 questionnaire questions given to 5 respondents, PT Lematang Coal Lestari (LCL) employees received very good responses. Keywords: Occupational Health and Safety, Transportation, Coal.

Abstract

This study aims to evaluate the productivity and work compatibility of loading and hauling equipment in overburden stripping activities at Pit PE of PT Priamanaya Energi, Lahat Regency, South Sumatra. The loading equipment used was a Komatsu PC 1250 excavator, while the hauling equipment consisted of Komatsu HD 785 dump trucks. The research method employed field surveys by collecting primary data in the form of cycle time for both loading and hauling equipment, supported by operational and field condition data. The analysis was conducted by calculating equipment productivity and match factor values. The results showed that the actual match factor was 0.78, indicating an imbalance in the working system and the presence of waiting time for the loading equipment. An evaluation was carried out by adding one hauling unit, resulting in an increased match factor of 0.98, which is close to the ideal condition. Factors affecting productivity include mining front conditions, haul road conditions, and loading patterns. Proper equipment matching can improve efficiency and productivity in overburden removal operations.Keywords: Productivity, Loading Equipment, Hauling Equipment, Match Factor, Overburden
