Abstract The fresh fish demand increase in the Sidoarjo district can be seen from the fish production amount increase which could be found in the fish market. The fish market became a fresh fish distribution center from fish farmers to customers. To keep the qualities of fish and its distribution services, designing the system design of fish distribution is need to be conducted. The aim of this research is to design a system design of fish distribution by integrating physical distribution service quality (PDSQ ) methods and lean six sigma methods at a fish market in Sidoarjo. This research is conducted to give a suggestion for fisheries and maritime department of Sidoarjo in providing services to public. This research began by measuring the quality of service by using the PDSQ method, then the highest of negative gap value would be identified to find “the waste” by lean method during the distribution process from producer to consumer which affects the quality of service, and than measured capability process using the six sigma method. By using both methods in implementing the system design improvement of fish distribution in Sidoarjo, the results show that the quality of services has increased the distribution of fish by the presence of some improvements facilities. These can be seen from the value of fish qualities which has increased in the reckoning of customer satisfaction from the gap value of each dimensions namely timeline of -2.08 becomes -0.81, availability dimension of -3.36 becomes -1.7, and condition dimension of -1.96 becomes -1.17, and scores of process capabilities of 4.11 becomes 4.43. The improvement of system design from this existing condition is by involving integrated service unit (UPT) of fish market as a control of the quality of fish and its distribution process to increase the customer satisfaction.

Abstract The goal of lean six sigma method is to solve the problems of waste, especially defect. The goal of failure mode and effect analysis (FMEA) method is to be able to identify potential failures in the production process of e.g. liquid soap bottle in order to reduce production failure and to have reference from FMEA highest risk priority number for corrective actions. The goal of fuzzy method is to improve priority risks of FMEA method. By using fuzzy method the priority risks with the same value can be eliminated so that only one highest value can be used as a reference for corrective action. Result of lean six sigma method are four types of critical defects i .e. dirty black, lines in the wall of the bottle, neck narrowed / clogged, and uneven surfaces. One result of the FMEA calculation with the highest risk priority number (RPN) is dirty black defect.This is due to less attention to the composition of the material and contamination / burnt crust. The highest score of RPN is 48 and ranked as the first priority for actions. While result of fuzzy calculations is the highest fuzzy risk priority number (FRPN) with value of 3.327831. This is caused by dirty black defect due to less attention to the composition of the material. Therefore from these results of the highest causes of defects can be used as a reference for corrective action.
