BP-algebra is a nonempty set with binary operation which satisfies the axioms (BP1) , (BP2) , (BP3) for each . In this research, the concept of - -derivation dan - -derivation in BP-algebra are defined along with its properties. Based on the concepts and - -derivation in B-algebra the properties of -derivation in BP-algebra are constructed. In the final part, the properties of the general…
