<![CDATA[Currently the Indonesian community was rife with long-distance communication must be use the internet facility. By using fasilitan via the Internet, hence more easy communication between each user, one of the connecting bridge that has been using social networking allows the user to communicate a lot like Facebook, Friendster, and Twiter. With many social networking facilities, then this study will provide an assessment in choosing among the three forms of social networking above and be an alternative choice. In assessing the third among alernatif social networking can be measured by several criteria such as level Popularities, Features, and Security, so that the results obtained from the analysis of the normalization of eigen value vector that can be obtained from each of the criteria can be described as follows: For the criterion level of popularity gained eigen value vector (0.4742), whereas the criteria associated with the eigenvalues obtained Features vector (0.1494), and for the safety criterion obtained eigenvalues vector (0.3764). With the basic use of the Random Index (RI) using a number n, then it can be searched value consistency Index (CI) and consistency ratio (CR) of the three social networks are as follows: In terms of criteria Popularity CI value (-1.1915) and CR (-2.0544), while the views of the criterion Features CI value (-1.1915) and CR (-2.0544) and visits from security criteria CI value (-1.1915) and CR (-2.0544).From the analysis of each value of consistency ratio (CR), it is concluded that this decision was acceptable, because the value of CR in the rules Analytic Hierarchical Process (AHP) must be worth less than 0.1 or a negative value. Keywords: analytic hierarchy process, eigen vector, consistency index, consistency ratio, decision making.]]>
