Schools with diverse student backgrounds need to take strategic steps in managing learning to get optimal learning outcomes. Good learning designs and techniques can motivate students' interest in learning. The teacher's role is very important in managing learning to create an effective teaching and learning process. Data Mining or also known as Knowledge Discovery in Database (KDD) is the process of extracting knowledge from large data to find new patterns to get new knowledge and information. Data Mining technology is used to explore existing knowledge in the database. One of the methods used in data mining is clustering with the K-Means algorithm. This study aims to conduct student clustering to obtain a balanced class composition in order to improve the quality and student learning outcomes as seen in the increasing in the class average score. The data processed in this study came from the main school data as many as 90 students of the XI class of Computer Network Engineering Skills Competency at SMKN Negeri 2 Padang Panjang in the 2020/2021 school year. The variables used in data processing are student scores, parents' income and the distance from where students live to school. The student clustering calculation using K-Means succeeded in grouping 90 students into 3 clusters where cluster 1 totaled 47 students, cluster 2 totaled 10 students and cluster 3 totaled 33 students. Each member of the cluster will be divided evenly into 3 groups studying to get a balanced class composition. This research can be used as a basis for decision making by schools in clustering student placements to improve learning outcomes. By the increasing in the grade point average, the school average score will also increased.</p> Yusma Elda, Sarjon Defit, Yuhandri Yunus, Raemon Syaljumairi Copyright (c) 2021 Jurnal Informasi dan Teknologi http://creativecommons.org/licenses/by/4.0 https://jidt.org/index.php/jidt/article/view/130 Thu, 30 Sep 2021 00:00:00 +0700 Prediksi dan Klasifikasi Buku Menggunakan Metode Backpropagation https://jidt.org/index.php/jidt/article/view/116 <p>Students of SMP Negeri 2 Lengayang have different interests in determining the books they are interested in, so that the library often has difficulty determining the books that are most entered by students, this is because they have not used the right system in determining the type and number of books, only based on the estimated number. Students and subjects only, as a result school students stock books of the books they want to borrow. Based on the above, a method is needed to predict and classify the amount of book stock in the future. The data used is a recap of monthly book lending, from 2018 to 2020 in the third month, with a total of 1653 transactions and 5 types of books processed, then the data is analyzed using the Backpropogation method. The results obtained are using a 5-3-1 pattern with a learning rate of 0.01, a goal of 0.01, the number of input units for the Weapon layer 5, the number of units in the hidden layer and the number of output layer units that are placed on 1 layer, and to carry out training using two phases namely feedforward and backpropagation phases. It is removed from this research that the backpropagation method can provide a classification prediction of the number of books that must be provided in the following year based on the number of data entered or the number of data entered.</p> R Rahmiyanti, Sarjon Defit, Yuhandri Yunus Copyright (c) 2021 Jurnal Informasi dan Teknologi http://creativecommons.org/licenses/by/4.0 https://jidt.org/index.php/jidt/article/view/116 Thu, 30 Sep 2021 00:00:00 +0700 Akurasi dalam Identifikasi Penyakit Sapi Pesisir Menggunakan Metode Forward Chaining https://jidt.org/index.php/jidt/article/view/117 <p>Coastal cattle are livestock that have economic value, such as selling beef and cattle breeds.
