After that, Fishbone Diagram is used to analyze the consequences by finding and describing the factors that cause existing problems. Then, improvement proposals are given and submitted by PDAM to be followed up by PDAM Kab.Banggai. The results of the Service Quality analysis of the quality of service of PDAM Kab. Banggai obtained a negative Gap in the Reliability dimension at attribute B5 (-1.200), in the Responsiveness dimension obtained a negative Gap at attribute C1 (-1.140), at attribute C2 with a negative Gap (-1.120) and in the Assurance dimension with a negative Gap (-0.560). The results of the analysis using Importance Performance Analysis obtained 4 attributes that are included in the top priority for improvement, namely the attributes contained in quadrant I. For further research, it is expected to conduct research to implement the proposed improvements given and analyze the quality of service after implementing the proposed improvements given by the author so that the effectiveness of the services that have been implemented can be known.]]>
