Permata Hati Duri Hospital is the largest private hospital in Duri City which also conducts monthly performance appraisals for employees. This study aims to create a performance appraisal system for Permata Hati Hospital employees that can make it easier for the hospital to assess employee performance. The criteria for employee performance appraisal used are competence, professionalism, communication, management and friendliness. The method used in this research is the fuzzy inference system Tsukamoto method. By using 100 employee data and using performance appraisal criteria from the hospital for one month, this study was able to produce an employee performance appraisal system by implementing the web-based fuzzy Tsukamoto method using the PHP programming language and MySQL as the database server. The number of rule bases used in the Tsukamoto fuzzy work step depends on the large number of criteria used. The final result obtained in the system is the employee value ranking that can be used for decision making for the hospital. The accuracy of this employee performance appraisal system is calculated by comparing the system output with the results of the direct score from the hospital assessment. The test results using 100 employee appraisal data indicate that the system built produces an accuracy of 84%. The result of this research is an employee performance appraisal system which is expected to facilitate the employee performance appraisal process, especially at Permata Hati Duri HospitalenEmployee Performance AppraisalTsukamoto Fuzzy Inference SystemArticle
