The development of information technology these days allows tourists to get information about tourist destinations very easily. One of the ways to get information about tourist destinations is from a guidebook. The purpose of this study is to evaluate the Kampung Heritage Kajoetangan's e-book application using the System Usability Scale method. The data was collected using a questionnaire. The respondents of this study are 40 people. The results show that the respondents considered the Kajoetangan travel guide e-book is already good and acceptable. However, looking at the NPS, the respondents tend to behave as promoters. Therefore, it is necessary to provide education and introduction of the application to the users (e.g. tour guides and the public). Thus, the problem of the lack of experience in trying the Kajoetangan travel guide e-book can be solved. In addition, developers, in this case, the researchers, must also improve the application, particularly regarding the complexity of the application so the public and tour guides, as the target users, can easily use it.

The focus of this research is RW 1, 9 and 10 Kauman Village, Klojen District. This study aims to identify the potential for historical tourism in Kajoetangan Village. This study uses a qualitative approach using in-depth interviews, documentation and observation. Then the collected data were analyzed descriptively. The results showed that Kajoetangan Village has a large enough historical tourism potential. Thus, it is possible to re-branding from the center of the economy to become a historical tourist spot. There are several things that become obstacles in its development, including the low level of literacy of the people of Kajoetangan Village towards historical tourism. Therefore, in this study a recommendation can be made that efforts to increase community literacy and resource conservation are needed to save the potential of historical tourism resources from further damage.
