Dalam penelitian ini, model fuzzy c-means akan digunakan untuk menentukan dosen pembimbing tugas akhir sesuai dengan bidang keahliannya. Penelitian ini dilakukan tidak sampai pada tahap pengujian, hanya sebatas perancangan perhitungan algoritma fuzzy c-means. Dari hasil analisis perancangan yang dilakukan dapat diketahui beberapa syarat dalam menentukan dosen pembimbing.

Therefore, in this study, a comparative analysis of the feasibility of students to be able to receive scholarship assistance will be carried out using the Moora and Topsis methods. Moora method is one of the methods in a decision support system where the way it works is by creating a normalization matrix and calculating the optimization value of each attribute, resulting in a ranking that is done by reducing the maximum and minimum values. While Topsis method is a method that produces rankings by making alternative preferences and comparing the results of the best alternatives. The variables used in the simulation of the eligibility analysis of scholarship recipients are the Grade Point Average (GPA), ...

It is intended that the information sent by the sender can be fully accepted by the recipient without interference from parties who are not interested in the information. Steganography techniques can be used to secure secret massages. Steganography is a method for hiding information on a media. Can be in the form of image, sound or video media. The most important aspect of steganography is the level security in hiding information, which refers to how much the third party is unable to detect hidden information. The goal is to avoid suspicion. Steganography commonly used is the hiding of text information on image media. The method used is Diversity. From the results of the trial, it is known that with Diversity insertion and extraction of massages can be done well.

Every year this college receives many registrations from students who have completed their education at the school stage. The large number of incoming student data makes it difficult for the admin to select new students who will register. In this study using the C4.5 algorithm data mining method to map the pattern of student admissions selection in the field of Engineering and computers. The attributes used are the average value of report cards (high, enough, low), basic academic ability tests (very high, high, medium, low, very low), basic computer knowledge tests (very high, high, enough, low, very low) and interviews (good, bad). Data mining is a mathematical calculation process that uses algorithms and requires large data. While the C4.5 algorithm is an algorithm that processes data by calculating entroph...
