In a variety of software development methods and their models of the activity process, no one does not have testing activities in their application. System testing is the last phase of testing that done by the developer in the internal work- space. However, phase of testing is not the end of the whole testing phase, since there is another stage to pass before the product deployment process, it is the acceptance testing. A popular method to perform the user acceptance testing is the usability testing, which in this method, the result provides the indication of the essential quality for the client to decide whether to approve or to deny the product. In this research of paper, we are going to do the usability testing by utilizing the System Usability Scale technique and the Net Promoter Score technique to measure appropriateness of the population information systems in the city of Tegal while we are also finding optimum testers required using the sampling technique. The result we earn trough this research is according to the Usability Testing result the proposed system developed by researchers is better than the current running system and the total testers participating on system testing is able to optimize using the sampling method.
