This study aims to examine the results of implementing strategies in developing tourism after the Covid-19 pandemic in Sibolga City. In previous studies, a model of tourism development strategy after the Covid-19 pandemic in the Lake Toba Region has been examined using the theory of the basic components of tourism consisting of tourist objects and attractions, accommodation, transportation / tourist transportation, tourist facilities and facilities, and tourism infrastructure (promotion, marketing and policy). Lake Toba and Sibolga are marine tourism destinations. This research applies the tourism development strategy found in previous research to Sibolga City. After the implementation, an evaluation was carried out through the Customer Satisfaction Index (CSI) questionnaire method, the Importance Performance Analysis (IPA) method and also interviews with tourists and tourism stakeholders involved in Sibolga City tourism. The results obtained from the calculation of the CSI value are 68.57%, in the range of 0.66% – 0.80%. The meaning of this value is that tourists are satisfied with the attributes measured by their satisfaction level. The average conformity score is 83.46%, meaning that the performance achieved and the importance of attributes according to travellers have shown excellent results. Through the FGD, it can be seen that the implementation of tourism development strategies from previous research in the Lake Toba Area is also appropriate
