Abstract
This study aims to analyze the influence interaction of bureaucratic culture, innovative culture, and supportive culture with job satisfaction on the performance of public service employees in the city of Kupang. The sample was determined as many as 100 people with a formula developed by Isaac and Michael at an error rate of 5%. Data analysis used path analysis techniques. The results showed that the interaction of bureaucratic culture, innovative culture and supportive culture with job satisfaction is not a good fit in predicting employee performance, so it can be said that job satisfaction is not a moderating variable. Without interaction, bureaucratic culture and supportive culture have a significant effect on the performance of public service employees, but innovative culture has no significant effect. The dominant cultural dimension describing the Kupang city government environment is the bureaucratic culture. So that people's expectations for a culture that is suitable for creative and innovative work environments as the dynamics of society are constantly changing are still far from reality.
