Abstract

The main requirements in the application of survival analysis are the starting time and the ending time of an event. Thus, the duration of visiting time in the Library of Syiah Kuala University (Unsyiah) Banda Aceh could be analyzed by using survival analysis. This study obtained primary data through an interview with the visitors of Unsyiah’s library. Total Samples were 105 visitors collected from three different floors of the library that is 35 visitors from each floor. The analysis was divided into two main steps. The first step was estimating the probability distribution of the visit time duration data through graphical analysis. The second step was calculating the probability density function (PDF), cumulative density function (CDF), survival, and hazard function of the data based on the appropriate distribution in the first step. Visitor behavior could be seen from the function of probabilities, survival and hazard of their visiting time duration. The PDF showed that the visitors tended to have smaller probabilities for being at the library when their visiting time duration increased, as well as their probabilities for staying after spending time of t hours that indicated with the survival function. On the other hand, they could leave the library anytimewith the same rate at 0.5259 according to the hazard function. In additional, the median estimation of visiting time duration based on the exponential distribution was really closed to the sample median that is 2.5 hours.
