"[ABSTRAK
Aplikasi Fajr merupakan aplikasi mobile yang memiliki konten islami dengan
fitur utama yaitu Fajr Cards. Namun, Fajr Cards belum mampu menarik
perhatian pengguna dengan minimnya jumlah pengguna fitur ini. Fajr Cards
sebagai fitur yang berbasiskan kepada konten dapat ditingkatkan dengan
memberikan konten yang relevan dengan pengguna. Twitter sebagai media sosial
memiliki data real-time dan jumlah yang banyak sehingga dapat menjadi sumber
data aktual untuk dianalisa. Data Twitter dapat dianalisa dengan menggunakan
text mining. Salah satunya yaitu text classification atau klasifikasi teks Tujuan
penelitian ini adalah untuk menentukan metode klasifikasi apa yang terbaik untuk klasifikasi tema konten Fajr Cards. Metodologi yang digunakan menggunakan tahapan preprocess Text Mining dan
penggunaan metode Text Mining yaitu Text Classification. Hasil yang diharapkan adalah gambaran bagaimana data Twitter diproses untuk proses klasifikasi dan metode klasifikasi apa yang terbaik untuk klasifikasi tema konten Fajr Cards.

Those data can be used as an actual source data for analyze. Text mining such as text classification will be used to analyze the data. The purpose of this research is to get what classification method that suited best for this classification. Methodology that used in this research is Text Mining including preprocess and Text Classification. The expected results is to know what classification method that suited best for Fajr Card?s theme classification.;Fajr application is a mobile application that contains Islamic contents for moslem

"Kanker merupakan penyakit penyebab kematian terbesar kedua di dunia. Menurut prediksi WHO 2015 kasus kematian akibat kanker akan meningkat menjadi 21,6 juta kasus pada tahun 2030. Salah satu usaha untuk mengurangi penyebaran kanker dengan menggunakan machine learning adalah melakukan pendeteksian jenis kanker dengan memanfaatkan microarray data. Pada umumnya, microarray data kanker terdiri dari banyak fitur. Namun, tidak semua fitur yang ada pada data kanker memiliki informasi penting. Oleh karena itu, fitur-fitur tersebut akan diekstraksi menggunakan metode Principal Component Analysis PCA. Kemudian dipilih fitur-fitur yang paling informatif dari data hasil ekstraksi PCA. Fitur-fitur terpilih dari data hasil ekstraksi akan dibentuk dalam data baru. Data sebelum dan data setelah dilakukan pemilihan fitur akan diklasifikasi menggunakan metode Fuzzy Support Vector Machines FSVM. Akurasi dari proses klasifikasi dua tahap tersebut akan dibandingkan. Pendekatan one versus one akan digunakan pada masalah klasifikasi multikelas data kanker leukemia. Dengan pendekatan tersebut akan terbentuk sebanyak k k-1 /2 masalah dua kelas, di mana k menunjukkan jumlah kelas. Hasilnya, tanpa melakukan pemilihan fitur, diperoleh akurasi tertinggi sebesar 87.69. Setelah dilakukan pemilihan fitur, diperoleh akurasi terbaik dengan menggunakan 60 fitur dengan akurasi sebesar 96,92.

Cancer is the second leading cause of death globally. According to WHO prediction 2015 cases of cancer deaths will increase become 21.6 million cases by 2030. One of the effort to reduce the spread of cancer by using machine learning is to detect the types of cancer. We can use microarray data to detect the types of cancer. In general, microarray cancer data consist of many features. However, not all features in cancer data have important information. Therefore, these features will be extracted by using Principal Component Analysis PCA method. Then, we select the most features who have important information of data extraction. The selected features of extracted data will be formed in the new data. Data, before and after selection will be classified using Fuzzy Support Vector Machines FSVM method. The accuracy of the classification process will be compared. The one versus one approach will be used on multiclass leukemia cancer data. This approach will formed the multiclass problem into k k 1 2 binary class problems, where k denotes the number of classes. The results, without doing feature selection, the highest accuracy is 87.69. After doing feature selection, the best accuracy is obtained by using 60 features with the accuracy is 96.92.

"ABSTRAK
Kanker merupakan salah satu penyebab kematian terbesar di seluruh dunia. Secara khusus, kanker otak adalah kanker yang terjadi pada sistem saraf pusat. Salah satu hal yang dapat dilakukan untuk penelitian kanker otak menggunakan machine learning adalah melakukan pendeteksian jenis kanker otak dengan memanfaatkan microarray data. Permasalahan tersebut merupakan masalah klasifikasi multikelas. Dengan menggunakan pendekatan one versus one, akan terbentuk sebanyak k k-1 /2 masalah dua kelas, di mana k menunjukkan jumlah kelas. Karena data kanker otak memiliki fitur yang sangat banyak, perlu dilakukan seleksi fitur. Pada penelitian ini, akan diimplementasikan metode Multiple Multiclass Support Vector Machine Recursive Feature Elimination MMSVM-RFE sebagai metode seleksi fitur, dan Twin Support Vector Machine TWSVM sebagai metode klasifikasi. Pada metode MMSVM-RFE dilakukan pelatihan SVM-RFE pada setiap masalah dua kelas, sehingga setiap masalah dua kelas memiliki pengurutan fitur masing-masing. Sebagai metode klasifikasi, TWSVM memiliki tujuan untuk mencari hyperplane masing ndash; masing kelas sedemikian sehingga data kelas satu sedekat mungkin terhadap suatu hyperplane namun sejauh mungkin dengan hyperplane lainnya. Rata-rata akurasi tertinggi pada simulasi menggunakan kernel linear pada MMSVM-RFE dan kernel linear pada TWSVM adalah 95,33 dengan menggunakan 200 fitur. Rata-rata akurasi tertinggi pada simulasi menggunakan kernel linear pada MMSVM-RFE dan kernel RBF pada TWSVM adalah 87 dengan 70 fitur. Sedangkan apabila proses validasi juga dilakukan pada seleksi fitur, rata-rata akurasi tertinggi yang diperoleh adalah 90,67 dengan menggunakan 90 fitur.

ABSTRACT
Cancer is one of main causes of death worldwide. Brain cancer is a type of cancer which occurs at central nervous system. Taking advantage from microarray data, machine learning methods can be applied to help brain cancer prediction according to its types. This problem can be referred as a multiclass classification problem. Using one versus one approach, the multiclass problem with k classes can be transformed into k k 1 2 binary class problems. The huge amount of features makes it necessary to use feature selection. In this research, Multiple Multiclass Support Vector Machine Recursive Feature Elimination MMSVM RFE method is implemented as the feature selection method, and Twin Support Vector Machine TWSVM method is implemented as the classification method. The main concept of MMSVM RFE is to train SVM RFE at each binary problem so that each binary problem will have their own arrangements of feature. As a classification method, TWSVM is trained to find two hyperplanes, each representative of its own class. The data of one class must be as near as possible from its representative hyperplane while also must be as far as possible from the other hyperplane. In the simulation which uses linear kernel on MMSVM RFE and linear kernel on TWSVM, the highest average accuracy is 95,33 , using 200 features. In the simulation which uses linear kernel on MMSVM RFE and RBF kernel on TWSVM, the highest average accuracy is 87 , using 70 features. In the case where the feature selection process is included in doing validation, the highest average accuracy is 90,67 , using 90 features."
