In this research the method that will be used is Aggregate Function.Aggregate Function is used to combine the results of the three criteria. The implementation of the Aggregate Function is done by calculating the average value of each concentration from the results of each criterion. The results of the first criteria are obtained using the User Based Collaborative Filtering method based on the Adjusted Cosine Similarity Algorithm. The results of the second criteria are obtained by calculating the average value of the certain mandatory courses that have been taken by the user.
