Abstrak - Kurikulum 2013 dirancang untuk memberikan kesempatan kepada siswa belajar berdasarkan minat siswa. Selain memilih mata pelajaran dalam suatu peminatan tertentu, siswa juga diberi kesempatan untuk mengambil mata pelajaran lintas minat.  SMA Negeri 1 Anyer salah satu sekolah yang telah menerapkan program lintas minat. Dalam proses penentuan kelas lintas minat disekolah tersebut masih mengalami kendala yaitu tidak terspesifikasinya siswa yang memiliki minat pada mata pelajaran tertentu, dan pada proses pemilihan lintas minat ditentukan oleh pihak sekolah. Penelitian ini bertujuan untuk  mengklasifikasi siswa berdasarkan minat dan bakat siswa pada mata pelajaran tertentu. Metode yang digunakan yaitu Decision Tree dan algoritma C4.5. Pada penelitian ini didapat nilai akurasi sebesar 82,82%. Penelitian menghasilkan sebuah sistem penentuan kelas lintas Minat. Model klasifikasi ini dapat membantu siswa dalam menentukan lintas minat dan dapat digunakan sebagai alternatif referensi bagi guru BK untuk dapat mengelompokkan siswa berdasarkan minat dan bakat siswa.   Kata Kunci : Algoritma C4.5, Decision Tree, Klasfikasi, Lintas Minat

C4.5 Decision Tree

Abstract The aim of this project is to compare some of the state-of-the-art machine learning algorithms on the classification of steers finished in feedlots based on performance, carcass and meat quality traits. The precise classification of animals allows for fast, real-time decision making in animal food industry, such as culling or retention of herd animals. Beef production presents high variability in its numerous carcass and beef quality traits. Machine learning algorithms and software provide an opportunity to evaluate the interactions between traits to better classify animals. Four different treatment levels of wet distiller’s grain were applied to 97 Angus-Nellore animals and used as features for the classification problem. The C4.5 decision tree, Naïve Bayes (NB), Random Forest (RF) and Multilayer Perceptron (MLP) Artificial Neural Network algorithms were used to predict and classify the animals based on recorded traits measurements, which include initial and final weights, sheer force and meat color. The top performing classifier was the C4.5 decision tree algorithm with a classification accuracy of 96.90%, while the RF, the MLP and NB classifiers had accuracies of 55.67%, 39.17% and 29.89% respectively. We observed that the final decision tree model constructed with C4.5 selected only the dry matter intake (DMI) feature as a differentiator. When DMI was removed, no other feature or combination of features was sufficiently strong to provide good prediction accuracies for any of the classifiers. We plan to investigate in a follow-up study on a significantly larger sample size, the reasons behind DMI being a more relevant parameter than the other measurements.

C4.5 Decision Tree

Stock selection rules are extensively utilized as the guideline to construct high performance stock portfolios. However, the predictive performance of the rules developed by some economic experts in the past has decreased dramatically for the current stock market. In this paper, C4.5 decision tree classification method was adopted to construct a model for stock prediction based on the fundamental stock data, from which a set of stock selection rules was derived. The experimental results showed that the generated rules have exceptional predictive performance. Moreover, it also demonstrated that the C4.5 decision tree classification model can work efficiently on the high noise stock data domain.

In current, there are complex relationship between the assets of information security product. According to this characteristic, we propose a new asset recognition algorithm (ART) on the improvement of the C4.5 decision tree algorithm, and analyze the computational complexity and space complexity of the proposed algorithm. Finally, we demonstrate that our algorithm is more precise than C4.5 algorithm in asset recognition by an application example whose result verifies the availability of our algorithm.Keywordsdecision tree, information security product, asset recognition, C4.5

Abstract In general, Zakat Information Systems is established to manage the zakat services, so that the data can be well documented. This study proposes the existence of a feature that will determine the amount of zakat received by Mustahik automatically using C4.5 Decision Tree algorithm. This feature is expected to make the process of determining the amount of zakat be done easy and optimal. The data used in this study are the data taken from Masjid An-Nur, Pancoran, South Jakarta. The experiment results show that the proposed feature produces an accuracy rate over 85%.
