In addition, the opinion of the respondents with the lowest value, regarding the events of culture in the village of Silalahi caused by lack of publication that circulates through a variety of media. We recommend organizing done periodically to be promoted widely and systematically. Then a bad response on support facilities is the lack of a number of environmental hygiene facilities that make uninteresting. Should the number of on-site cleanliness can be improved for the cleanliness of tourist sites. In addition, the difficulty of finding a place of worship (small mosque) in Silalahi is caused by non-Muslim majority. See the increasing tourist visits, planning small mosque should be immediately planned. A bad response is also given, that there are no souvenir shops along the village Silalahi. But souvenir shops is an attraction tourism destination. In addition, the lack of a marker Board needs the right amount of tourists because it helps in communicating with people who read it. Auxiliary facilities component that gets a bad response is a central information and supporting equipment that requires a development plan, as it will make it easier for tourists to travel tourists and also benefit local communities the village Silalahi.
