Abstract

The system created to compare the most efficient method among Frequent Pattern Tree method, SQL Based Pattern Mining method and conventional data storage for storing List of Participants Course (DPMK) Information Technology Faculty of Tarumanagara University (FTI Untar). Frequent Pattern Tree method is a method that forming a pattern of courses taken by students using a tree structure. Based Pattern Mining SQL method is a method that forming a pattern of courses by combining the data DPMK becomes a itemsets and take advantage of the features found on the Structured Query Language (SQL) to improve its performance. Conventional data storage is storing DPMK without forming a pattern of courses. The results of the three storage methods are used to form Student Attendance List report and Student Study Cards report. The results show SQL-Based Pattern Mining method is the most efficient method when viewed from the data needed to store and the length of upload time compared to Frequent Pattern Tree method and conventional data storage. However the data call duration used in forming Student Attendance List report and Student Study Cards report using conventional data storage method are  faster than method that use a pattern of courses. Key wordsDafta Peserta Mata Kuliah, Frequent Itemset, Frequent Pattern Mining, Frequent Pattern Tree, SQL Based Pattern Mining

Abstract

An application of exams and courses scheduling is made using Vertex Graph Colouring, Particle Swarm Optimization, and Constraint Based Reasoning method to produce a valid and optimal exam and course schedule which can also fulfill the demands of special schedule and room needs. FTI Untar is used as a study case in this development.  The results of the tests done for the courses scheduling of even semester of 2010 / 2011 till odd semester of 2012 / 2013, without collision of special preferences, show that on average there’s no hard-constraints (constraints that must be satisfied) violation, only 13% of soft-constraints (constaints that are attempted to be satisfied) violations between each course and 6% soft-constraints violation due to the poor preference score of the room or time used.  Whilst, the results of the tests done for the exams scheduling of odd semester of 2011 / 2012 and 2012 / 2013 show that on average there’s no hard-constraint and soft-constraint violation between each course although there is still 1% soft-constraints violation due to the poor preference score of the room used. The development was tested to the Secretariat of Informatics Department in FTI Untar and obtain a positive response because of the user-friendly user interfaces and can help to accelerate the process of course, practicum, and exam schedule’s report making.

Abstract

Class offers and scheduling application is made by using k-medoids and alternative graph coloring approach. This application optimizes the offers of class scheduling. The sample case is Faculty of Information Technology at Tarumanagara University. k-Medoids is used to acquire the number of classes that need to be offered on new semester and alternative graph coloring approach is used to acquire the class that has been adjusted with lecturer’s time and room availability. The results still indicate the violation of soft constraint. The most frequent violation of soft constraint is the mismatch schedule to lecturer’s time availability. Key wordsAlternative Graph Coloring Approach, Fakultas Teknologi Informasi Universitas Tarumanagara, k-Medoids, University Course Timetabling Problem

Abstract

The system created are used to predict the length of study period required for students to complete their studies based on their grades. The system created also have online consultation features that students use with their academic lecturer for academic consultations. To find the model tree with good accuracy, the system will use k-fold cross validation in the process of making model tree. Testing prediction system using students data from 2008 to 2012 who have completed their studies. The value data used is all mandatory courses  in the Faculty of Information Technology except for thesis courses. Based on the tests performed, the system can already run and used in accordance with the design made. The test is to compare the accuracy of the selected tree model from different k values in the k-fold cross validation process. The results obtained show that if the value of k the greater, then the accuracy obtained better.

Abstract

E-commerce is currently widely used by companies to offer and provide information that can be in the form of products or services to quickly and accurately. In addition to quick and accurate, the information which stored in database must can be accessed anywhere and anytime. With the growth development of technology, the database can be accessed through mobile devices such as devices with Android operating system via Internet. In accessing the database from another device via Internet needed an interface or bridge that can be used and accessed by a wide variety of programming languages. Bridge or a interface is called a web service. With the existence of these technologies, e-commerce can be evolved into mobile e-commerce. Therefore  2 applications are made to support e-commerce which is web application and mobile application. Both applications show the products in accordance with the database of the company

Abstract

Class, laboratory, and substitute class application is made by using Iterative Forward Search. This application will deliver optimized schedule of class, laboratory, and substitute class scheduling. The sample case is Faculty of Information Technology at Tarumanagara University. Iterative Forward Search is used to deliver schedule of class, laboratory, and substitute class with consideration of part time lecturer’s time availability, no violation of hard constraint, and as few as possible violation of soft constraint. The results still indicate the violation of soft constraint and the mismatch schedule to part time lecturer’s time availability. The most frequent violation of soft constraint is when two classes; one class is in year x and the other one is in year (x-2) or year (x+2); were scheduled in the same timeslot. The mismatch schedule to part time lecturer’s time availability is caused by violation of hard constraint in the pointed timeslot. Key wordsIterative Forward Search, Fakultas Teknologi Informasi Universitas Tarumanagara, University Course Timetabling Problem
