Binary Search Tree is one of the most useful fundamental data structure for dynamic datasets. It can be used to sort numerical data, character string and any other data in a sophisticated way. However, the performance in term of processing time for Binary Search Tree increases when a data become large, especially for data mining and detecting pattern in DNA sequences. To increase speed performance of Binary Search Tree, there are several strategies were applied such as using super computing or conducting parallel programming. In this research we applied parallel programming by using Message Passing Interface (MPI) to sort numerical data. This method is more efficient and less cost compare with using super computing. The basic idea of parallel programming is dividing root into sub-root and executing sub-root simultaneously on multiple cores. MPI provides a set of send and receive function that allow data to be processedon multiple cores. This method is very useful to find and delete data faster than in a sequential way, but the consequence is the coding time takes little bit longer than usual.
Key word : Binary search tree, Message passing interface,  Parallel Programming.
