Dalam dunia kesehatan, penyakit jantung merupakan penyakit yang mendorong angka kematian yang cukup tinggi, sehingga banyak penelitian yang dilakukan sebelumnya untuk memprediksi penyakit jantung. Dalam penelitian ini dilakukan perbandingan metode data mining yaitu algoritma neural network, k-nearest neighbordan C4.5 yang diaplikasikan pada data pasien baik yang sehat dan sakit. Dari hasil pengujian dengan mengukur kinerja ketiga metode tersebut menggunakan cross validation, confusion matrix dan kurva ROC, diketahui bahwa neural network memiliki nilai akurasi yang paling tinggi yakni sebesar 86,06%, diikuti oleh metode algoritma C4.5 dengan nilai akurasi 82.92%, kemudian metode k-nearest neighbordengan akurasi 77,58%. Nilai AUC untuk metode neural network menunjukan nilai tertinggi yakni 0,913 dan yang terendah adalah metode C4.5 yaitu 0,857.Kata Kunci: data Mining, algoritma neural network, k-nearest neighbord dan C4.5

Heart disease is the occurrence of partial or total blockage of a blood vessel over, as a result of the self peyumbatan deep chemical energy supply to the heart muscle is reduced, resulting in impaired balance between supply and needs .Research in predicting heart disease have been carried out by several previous investigators. In this study will be done for heart disease prediction algorithm using C4.5 and improved the performance of C4.5 algorithm using Adaboost method is implemented on the data of heart disease patients. From the test results by measuring method using a C4.5-based Adaboost, confusion matrix, and the ROC curve, it is known that C4.5 algorithms yield accuracy values 86,59%, AUC values obtained after 0.957 and optimized by using the method to be 92,24% Adaboost, the AUC to 0.982. by looking at the accuracy and AUC values after the optimizations, the algorithmbased C4.5 classification Adaboost into the category of groups is very good, because AUC values between 0.90 – 1.00

There is a change in the curriculum as well as the increasing number of students from year to year, many criteria are used in determining student majors according to the interests of students talent and desires. With these constraints it will affect the calculations process, so that the results obtained later do not rule out the possibility of non-objective selection. Therefore, the process of majoring in sma negeri 1ungaran which is still done manually need to switch digitization, namely by making a Decision Support System which will later be more effective, efficient and determined according to exixting criteria. This research was designed and developed using the PHP and MYSQL programming languages as the database and using the Simple Additive Weighting (SAW) method to perform weighted summation calculations containing ceveral criteria. From the results of testing using blackbox shows that this program can work according to its function, namely being able to input data and perform calculations for determining student majors. As well as accuracy testing which produces a fairly good level of accuracy of 80% from 100%. From the results of this study, it can be concluded that this system can determine students majors according to their academic interests and talents. And provide effectiveness and efficiency of teachers in helping majors.
