Abstract

Unbalanced data classification is a crucial problem in the field of machine learning and data mining. Data imbalances have a poor impact on classification results where minority classes are often misclassified as a majority class. Conventional machine learning algorithms are not equipped with the ability to work on unbalanced data, so the performance of conventional algorithms is always not optimal. In this study, ensemble learning using SMOTEBagging method was applied to classify 11 unbalanced datasets. SMOTEBagging performance is also compared with three types of conventional classification algorithms namely SVM, k-NN, and C4.5. By applying the 5 cross-validation scheme, the AUC value generated by SMOTEBagging is higher at 10 datasets. The mean values of the lowest to highest AUC were obtained by SVM, k-NN, C4.5 and SMOTEBagging algorithms with values 0.638, 0.742, 0.770 and 0.895. By applying Friedman test it was found that the performance of AUC SMOTEBagging differed significantly with the other three conventional methods SVM, k-NN and C4.5ENSEMBLE LEARNING DENGAN  METODE  SMOTEBagging PADA KLASIFIKASI DATA TIDAK SEIMBANG

Abstract

Mathematics is one of the subjects that tend to be less favored by students, especially the students of grade 1 primary school. The students prefer to draw or other mathematics that are visual compared to mathematics. Therefore, in this research try to combine the mathematical material in the form of visual which is animation and also use the character of drawing which is liked by the children, so that the student is more interested in the learning process of mathematics. Selection of programming in writing this research using macromedia flash application. With the help of information technology and programming languages, especially animation, there will be many benefits that can be obtained. In this case the teacher is easier in delivering the material and students more easily in absorbing the material delivered so that the learning process can run more effectively and efficiently. And with the role of this learning media can overcome the problem of lack of interest in learning students of mathematics subject matter and of course increase the value of students in exercises or exams conducted in schools. Keywords: Role; Media; Learning; Math

Abstract

Dalam penyelenggaraan ibadah di gereja, sebagian besar informasi termasuk materi ibadah disampaikan kepada jemaat melalui penggunaan proyektor atau layar lebar berteknologi LED. Namun, banyak juga gereja yang belum memiliki kemampuan finansial untuk pengadaan media tersebut. Di sisi lain, gereja juga mendukung praktek ramah lingkungan, khususnya dalam mengurangi penggunaan kertas dengan beralih ke sistem digital. Artikel ini akan membahas solusi alternatif untuk mengatasi persoalan di atas, yang berupa pengembangan sistem informasi gereja berbasis web yang dinamakan iGreja, yang berfungsi membantu jemaat khususnya dalam hal penyediaan informasi digital, misalnya: teks liturgi, data kehadiran yang dibedakan atas jenis kelamin, daftar petugas beserta penugasannya, nama pendeta dan tema kotbah, nilai total persembahan untuk suatu tanggal dan waktu penyelenggaraan dapat diakses melalui dashboard yang tersedia. Sementara itu, teks liturgi, materi renungan dan berita gereja dapat dilihat dan/atau diunduh dari halaman web.

Abstract

ABSTRAKAlgoritma Round Robin merupakan salah satu algoritma penjadwalan proses yang digunakan secara luas didalam penjadwalan CPU. Algoritma Round Robin menggunakan sistem time sharing  dengan static quantum time untuk setiap proses yang akan dieksekusi CPU. Algoritma ini tergantung pada ukuran quantum time yang diberikan. Jika quantum time terlalu besar, maka respons time untuk proses-proses terlalu tinggi. Sebaliknya, jika quantum time terlalu kecil, maka dapat mengakibatkan overhead pada CPU dimana context switching dari proses menjadi lebih besar. Pada penelitian ini, untuk meningkatkan performa CPU dengan memperkecil waiting time dan turnaround time dilakukan modifikasi terhadap algoritma Round Robin dengan menggunakan dynamic quantum time serta sorting proses secara ascending. Dilakukan pengujian terhadap antrian proses dan hasilnya dengan menggunakan algoritma Round Robin yang dimodifikasi ini didapat average waiting time dan average turnaround time yang lebih kecil dibandingkan menggunakan algoritma Round Robin Klasik. Kata kunci: Quantum Time, Static Quantum Time, Dynamic Quantum Time, Ascending,     Average Waiting Time, Average Turnaround Time
