ABSTRAK Informasi diperkirakan lebih dari 80% tersimpan dalam bentuk teks tidak terstruktur. Oleh karena itu, dibutuhkan sistem pengelolaan teks yaitu dengan metode text mining yang diyakini memiliki potensial nilai komersial tinggi. Salah satu implementasi dari text mining yaitu klasifikasi teks. Tidak hanya dokumen, pemanfaatan klasifikasi juga digunakan pada surat. Peneliti mengkaji Multinomial Naive Bayes Classifier untuk mengklasifikasi surat keluar sehingga dapat menentukan nomor surat secara otomatis. Sistem klasifikasi didukung dengan confix-stripping stemmer untuk menemukan kata dasar dan TF-IDF untuk pembobotan kata. Pengujian diukur dengan menggunakan confusion matrix. Dari hasil pengujian menunjukkan bahwa implementasi Multinomial Naive Bayes Classifier pada sistem klasifikasi surat memiliki tingkat accuracy, precision, recall, dan F-measure berturut-turut sebesar 89,58%, 79,17%, 78,72%, dan 77,05%.  ABSTRACT The information estimated that more than 80% is stored in the form of unstructured text. Therefore, it takes a text management system, namely text mining method is believed to have high potential commercial. One of text mining implementation is text classification. Not only documents, the use of classification is also used in official letter. Researcher examined Multinomial Naive Bayes Classifier to classify the letter so it can determine the letters classification code automatically. The classification system is supported by confix-stripping stemmer to find root and TF-IDF for term weighting. The test used by confusion matrix of a classified as a measure of its quality. The test results showed that the implementation of Multinomial Naive Bayes Classifier on letter classification system has a level of accuracy, precision, recall, and F-measure respectively for 89.58%, 79.17%, 78.72% and 77.05%.How to Cite : Setianingrum, A.

Tingginya minat siswa untuk melanjutkan sekolah ke jenjang yang lebih tinggi berpengaruh pada tingginya jumlah mahasiswa yang terdaftar di Indonesia. Kesulitan dalam menyelesaikan perkuliahan menjadi masalah yang sering terjadi, salah satu penyebabnya adalah ketidak-sesuaian potensi diri dengan program studi yang dipilih. Penelitian ini menjadikan FIK Universitas Amikom Yogyakarta sebagai tempat studi kasus untuk mencari tahu korelasi potensi diri dengan IPK mahasiswa, mencari potensi diri terbaik pada masing-masing program studi serta mencari tahu akurasi metode naive bayes dalam mengklasifikasi potensi diri mahasiswa. Responden yang digunakan dalam penelitian ini berjumlah 50 orang yang terdiri dari mahasiswa minimal semester 4, alumni dan 1 pakar. Pengumpulan data menggunakan metode wawancara dan koesioner, sedangkan pengolahan data menggunakan metode naive bayes classifier, confusion matrix untuk pengujian, dan korelasi pearson product moment untuk mencari tahu ada tidaknya korelasi. Penelitian ini mendapatkan hasil bahwa potensi diri kemampuan logika, visual dan interpersonal berpengaruh terhadap tingginya IPK mahasiswa dimana nilai signifikansi logika=0.043<0.05, interpersonal=0,029<0.05 dan visual=0,05<0.05. Kemampuan logika cenderung akan berdampak baik pada IPK mahasiswa prodi S1-SI, S1-IF, serta S1-TK, sedangkan kemampuan visual berdampak baik pada program studi S1-TI, D3-MI dan D3-IF. Naive bayes juga diketahui memiliki tingkat akurasi sebesar 90,625% dalam mengklasifikasikan mahasiswa berdasarkan potensi diri. Kata Kunci — bayes, IPK, mahasiswa The high interest of students to continue their education has an effect on the high number of students in Indonesia. Difficulties in completing lectures become a problem that often occurs, one of the reasons is incompatibility study program and student talents. This research made FIK Amikom University Yogyakarta as a case study to find out the correlation of Grade Point average (GPA) and student talents, best talents that’s needed in each study program and the accuracy of naive bayes in classifying students' talents, 50 people consisting of students at least semester 4, alumni and 1 expert as respondents. Data collection uses interview and questionnaire methods, while data processing uses the naive bayes classifier, confusion matrix for testing, and Pearson product moment correlation to find out whether there is correlation. This study found that the self-potential logic, visual and interpersonal abilities influence the high GPA of students where the significance value of logic=0.043<0.05, interpersonal=0.029<0.05 and visual=0.05<0.05. Logical ability tends to have a good impact on the GPA of S1-SI, S1-IF, and S1-TK study program, while visual abilities have an impact on S1-TI, D3-MI and D3-IF. Naive Bayes is also known to have an accuracy rate of 90.625% in classifying students based on their talents. Keywords — bayes, GPA, students

Toxic comments are comments made by social media users that contain expressions of hatred, condescension, threatening, and insulting. Social media users who are on average still teenagers with a nature that still cannot be controlled completely becomes a matter of great concern when they comment, their comments can be studied as text processing. Sentiment analysis can be used as a solution to identifying toxic comments by dividing them into two classifications. Where the data used amounted to 1,500 taken from social media Facebook in the private group Arena of Valor community. The dataset is divided into 2 classes: toxic and non-toxic. This research uses Naive Bayes with TF-IDF transformation and Information Gain feature selection and use distribution ratio 80:20. It will be compared the results of the evaluation where Naive Bayes without transformation, using TF-IDF transformation, and TF-IDF using Information Gain feature selection. The results of the comparison of evaluations from confusion matrix that have been carried out obtained the best classification model is to use the ratio of training and testing data 80:20 with TF-IDF transformation resulting in an accuracy of 75%, precision of 63%, recall of 67%, and F-measure of 64%.

Based on Indonesia's health profile in 2008, Diabetes Mellitus is the cause of the ranking of six for all ages in Indonesia with the proportion of deaths of 5.7% under stroke, TB, hypertension, injury and perinatal. This is reinforced by WHO (2003), Diabetes Mellitus disease reached 194 million people or 5.1 percent of the world's adult population and in 2025 is expected to increase to 333 million inhabitants. In particular, in Indonesia, people with Diabetes Mellitus are increasing. In 2000, Diabetes Mellitus sufferers have reached 8.4 million people and it is estimated that the prevalence of Diabetes Mellitus in 2030 in Indonesia reaches 21.3 million people.This allows researchers and practitioners to focus their attention on detecting/diagnosing diabetes mellitus and to prevent it because the disease can cause complications. The method used in this research was problem identification, data collection, pre-processing stage, classification method, validation and evaluation and conclusion. The algorithm used in this research was CART and Naïve Bayes using dataset taken from UCI Indian Pima database repository consisting of clinical data ofpatients who detected positive and negative diabetes mellitus. Validation and evaluation method used was 10-crossvalidation and confusion Matrix for the assessment of precision, recall and F-Measure. The result of calculation has been done, got the accuracy result on CART algorithm equaled to 76.9337% with precision 0.764%, recall 0.769%, and F-Measure 0.765%. Whilethe diabetes dataset was tested with the Naïve Bayes algorithm, got an accuracy of 73.7569% with precision 0.732%, recall 0.738%, and F-Measure 0.734%. From these results it can be concluded that to diagnose diabetes mellitus disease it is suggested to use CART algorithm.

AbstractHoax news in Indonesia spread at an alarming rate. To reduce this, hoax news detection system needs to be created and put into practice. Such a system may use readers’ feedback and Naïve Bayes algorithm, which is used to verify news. Overtime, by using readers’ feedback, database corpus will continue to grow and could improve system performance. The current research aims to reach this. System performance evaluation is carried out under two conditions ‒ with and without sources (URL). The system is able to detect hoax news very well under both conditions. The highest precision, recall and f-measure values when including URL are 0.91, 1, and 0.95 respectively. Meanwhile, the highest value of precision, recall and f-measure without URL are 0.88, 1 and 0.94, respectively.
