The expensive lobster selling value is inversely proportional to the income received by fishermen, the problems faced are influenced by several factors, namely whether, fishing regulations, and technology used, lobster sales will increase if the sales process if fishermen can sort and sort lobster sized large, which has a very high export value, the problems faced by fishermen currently sell directly to the fish market or buyers without going through the grading process. The grading system can be done manually but this causes the lobster to become not fresh because of the fairly long sorting process. The sorting and grading system method is a must so that a sold lobster possesses export value and quality, some large fishermen use a very large and fairly expensive sorting tool and are only owned by
