<p align="justify">In open pit coal, overburden stripping is one of the most important things in open pit mining method. Overburden material is usually dump at waste dump. Dozer is usually used for dozing the waste material at waste dump to spread or remove the muck pile. PT Bukit Makmur Mandiri Utama (BUMA) is a mining service company for overburden removal and coal mining. Dozer D155A and D375A are used to dozing waste material at waste dump in Pit Paringin, PT Adaro Indonesia. The purpose is to calculate the needs of bulldozers and their combinations. The research methods are literature study (Performance Handbook Komatsu 27th Edition), observation in the field (Pit Paringin), and collection data from the company. As informed from the company, the amount of waste material in June is 3,235,300 m3. By using the dozing productivity equation and finding match factor to the production target overburden material per hour is close to 1, as the results 4 units of D375A or the combination of 3 units of D375A and 2 units of D155A are being used.<p align="justify">
