9 Coal Preparation, Environmental, Safety Technology Dissemination Training Outline :

 In fiscal year 2018, has conducted lectures in 10 places of mining faculties and colleges (total participants were 424 people)

 Regarding the content of the training, it is mostly good, and the reason for participating in the training is the desire to improve the participants' own abilities.

 More than half of the graduates of that participated in the training are going to coal and mining private companies, and it is highly likely that the knowledge gained through this training project will be utilized. 〇 Training location, schedule, number of participants 〇 Evaluation in five level of each training subject, training time, text content, etc. as seen by trainees No TRAINING LOCATION NUMBER OF TRAINEE 1 Mining Faculty of STTIND Padang (Padang Industrial Technology College) (Padang) 42 2 Mining Faculty of Jambi University (Jambi) 40 3 Coal Faculty of Akamigas Polytechnic () 52 4 () 40 5 Mining Faculty of (Jakarta) 47 6 Mining Faculty of Lambung Mangkurat University (Banjarbaru) 35 7 Mining Department of Engineering Faculty of Bandung Islamic University (Bandung) 50 8 Palangkaraya University (Palangkaraya) 40 9 Mining Department of Engineering Faculty of UPN Veteran Yogyakarta (Yogyakarta) 45 10 Yogyakarta National Institue of Technology (Yogyakarta) 33 Total 424 〇 Reason for choosing this training

Comment from the director of the 〇 university who participated in the Employment status of university graduates who participated in the training training There are many students who want to participate, so I hope that this training will be held next year. (Lambung Mangkurat University) Through the dissemination of safety technology at the mine in the training held in collaboration with HRDCGMC with JOGMEC, this is one step to reduce and eliminate accidents at mines and coal mines in the province of Central Kalimantan.
