The problem of cutting raw materials to fulfill the size of demand using certain cutting pattern is called Cutting Stock Problem (CSP). CSP aims to find the optimal cutting pattern with the minimum trim loss. In this research, all possible cutting patterns were generated by pattern generation algorithm where the materials were cut based on the length on the first stage and the width on the rest stage. All patterns were modeled to  N -Sheet model and solved using Branch and Cut method. Based on the results, it showed that the  N -Sheet model ensured as minimum a possible trim loss to fulfill the demands.
