This paper chiefly deals with the performance of DSTATCOM as a load compensator. For enhancing the power quality and so as to mitigate harmonics it is employed on the load side. The reactive power is absorbed or generated by DSTATCOM by regulating the bus voltage. The most reason for occurring of the power quality issues is because of the non-liner loads that were employed by the consumers. DSTATCOM works as inductive or capacitive modes basing on the system voltage. The analysis is performed on the issues in the distribution side by employing the DSTATCOM compensation in this paper. In this paper,we had adopted Instantaneous Symmetrical Compound Theory (ISCT) controller to mitigate harmonics on the source side. The harmonics are due to the increase in the usage of non-linear loads by the consumers. The DSTATCOM regulates the bus voltage by absorbing or generating reactive power. The results are extracted using extensive digital simulation performed in MATLAB/SIMULINK environment.

Objectives of this study were analyze fish auction participant satisfaction to auction services in TPI Morodemak, analyze attributes effect, services that fit to service quality measurement, and analyzed fish auction participants perception to performance and importance for fish auction house Morodemak services. Used descriptive method and purposive sampling with 49 respondents consists of commercial fishmongers, traditional fishmongers, purse seine owners, and boat lift net owners as fish auction participant. Satisfication measurement used Customer Satisfication Index (CSI), Importance and Performance Analysis (IPA) and gap analysis. Results from this study were value CSI 20% (0.2) indicate the auction participants dissatisfied with the services provided, IPA show there are four attributes should be develop, two elements have not been completed based on measurement requirements of service satisfaction, gap value average -0.05 means the auction participants were not satisfied with the performance of TPI services because the performance value was lower than the importance value.

The Tax Payer obidience in fulfiling their taxation obligation will be influenced a lot by the satisfaction level toward the service fiscus. The aim of this observation is to know the response of Tax Payer toward service quality through importance and performance. The population which become the object of this observation is the personal Tax Payer registered in Bogor Tax Service Office and the number of respondents taken as the sample are 100 respondents with Slovin formula. The analysis method used is descriptive analysis and importance-performance analysis.   The result of this observation will be able to be used as one of the input to Bogor Tax Service Office in improving the quality service and for the following observation, especially those who take the same object as the observation in order to improve the quality service to the Tax Payer based on the service of its working way which is felt less. Otherwise it is important for The Tax Payer, maintaining the good work or balancing the service quality based on the working way which is evaluated less important by The Taxe Payer, but has been done reasonably well or very well by The Service Office
