High accuracy value is one of the parameters of the success of classification in predicting classes. The higher the value, the more correct the class prediction. One way to improve accuracy is dataset has a balanced class composition. It is complicated to ensure the dataset has a stable class, especially in rare cases. This study used a blood donor dataset; the classification process predicts donors are feasible and not feasible; in this case, the reward ratio is quite high. This work aims to increase the number of minority class data randomly and synthetically so that the amount of data in both classes is balanced. The application of SOS and ROS succeeded in increasing the accuracy of inappropriate class recognition from 12% to 100% in the KNN algorithm. In contrast, the naïve Bayes algorithm did not experience an increase before and after the balancing process, which was 89%.

Pada era sekarang kebutuhan akan informasi sangat tinggi, sehingga diperlukan pemprosesan data yang cepat, akurat, dan tepat. Informasi yang dihasilkan harus berkualitas sehingga dapat digunakan ?untuk pengambilan keputusan. Algoritma Simple Multi Attribute Rating Technique (SMART) adalah algoritma yang digunakan untuk pengambilan keputusan dengan menggunakan multi kriteria, ?setiap kriteria memiliki nilai dan diberikan kepada setiap alternatif sehingga menghasilkan jumlah peringkat pembobotan untuk mendapatkan alternatif terbaik. Penggunaan algoritma SMART tidak dapat menentukan hasil secara spesifik, tetapi hanya berdasarkan peringkat tertinggi, untuk mengatasi hal tersebut penelitian dikombinasikan dengan algoritma Forward Chaining. Proses algoritma Forward Chaining mensinkronkan fakta-fakta yang ada dengan rule yang telah ditetapkan dengan cara penelusuran secara runtut maju melalui penalaran logika IF-THEN. Kombinasi kedua algoritma tersebut telah menghasilkan sebuah sistem pendukung keputusan yang digunakan tidak hanya untuk penyeleksian calon anggota sebuah organisasi tetapi sistem dapat memberikan rekomendasi posisi atau jabatan kepada anggota tersebut.

Preprocessing is an essential task for sentiment analysis since textual information carries a lot of noisy and unstructured data. Both stemming and stopword removal are pretty popular preprocessing techniques for text classification. However, the prior research gives different results concerning the influence of both methods toward accuracy on sentiment classification. Therefore, this paper conducts further investigations about the effect of stemming and stopword removal on Indonesian language sentiment analysis. Furthermore, we propose four preprocessing conditions which are with using both stemming and stopword removal, without using stemming, without using stopword removal, and without using both. Support Vector Machine was used for the classification algorithm and TF-IDF as a weighting scheme. The result was evaluated using confusion matrix and k-fold cross-validation methods. The experiments result show that all accuracy did not improve and tends to decrease when performing stemming or stopword removal scenarios. This work concludes that the application of stemming and stopword removal technique does not significantly affect the accuracy of sentiment analysis in Indonesian text documents.

Work on student assignments and assessments are done manually so that evaluation cannot be done objectively because many tasks are similar or even the same as other student assignments. Copying other people's work is unlawful; students lack an understanding of the definition of plagiarism. Therefore education about this is done early, especially for the world of knowledge, which incidentally really appreciates the work of others. Making plagiarism software is needed to answer these challenges; this service activity provides training to teachers in managing online-based student assignments and checking assignment documents using plagiarism software. This activity can make it easier for teachers to offer assignment assessments and provide students with an understanding of the originality of a work.

Salah satu cabang ilmu komputer yaitu pembelajaran mesin (machine learning) menjadi tren dalam beberapa waktu terakhir. Pembelajaran mesin bekerja dengan memanfaatkan data dan algoritma untuk membuat model dengan pola dari kumpulan data tersebut. Selain itu, pembelajaran mesin juga mempelajari bagaimama model yang telah dibuat dapat memprediksi keluaran (output) berdasarkan pola yang ada. Terdapat dua jenis metode pembelajaran mesin yang dapat digunakan untuk analisis sentimen: supervised learning dan unsupervised learning. Penelitian ini akan membandingkan dua algoritma klasifikasi yang termasuk dari supervised learning: algoritma K-Nearest Neighbor dan Support Vector Machine, dengan cara membuat model dari masing-masing algoritma dengan objek teks sentimen. Perbandingan dilakukan untuk mengetahui algoritma mana lebih baik dalam segi akurasi dan waktu proses. Hasil pada perhitungan akurasi menunjukkan bahwa metode Support Vector Machine lebih unggul dengan nilai 89,70% tanpa K-Fold Cross Validation dan 88,76% dengan K-Fold Cross Validation. Sedangkan pada perhitungan waktu proses metode K-Nearest Neighbor lebih unggul dengan waktu proses 0.0160s tanpa K-Fold Cross Validation dan 0.1505s dengan K-Fold Cross Validation.

Background: Hate speech is an expression to someone or a group of people that contain feelings of hate and/or anger at people or groups. On social media users are free to express themselves by writing harsh words and share them with a group of people so that it triggers separations and conflicts between groups. Currently, research has been conducted by several experts to detect hate speech in social media namely machine learning-based and lexicon-based, but the machine learning approach has a weakness namely the manual labelling process by an annotator in separating positive, negative or neutral opinions takes time long and tiringObjective: This study aims to produce a dictionary containing abusive words from local languages in Indonesia. Lexicon-base is very dependent on the language contained in dictionary words. Indonesia has thousands of tribes with 2500 local languages, and 80% of the population of Indonesia use local languages in communication, with the result that a significant challenge to detect hate speech of social media.Methods: Abusive words surveys are conducted by using proportionate stratified random sampling techniques in 4 major tribes on the island of Java, namely Betawi, Sundanese, Javanese, MadureseResults: The experimental results produce 250 abusive words dictionary from 4 major Indonesian tribes to detect hate speech in Indonesian social media by using the lexicon-based approach. Conclusion: A stratified random sampling technique has been conducted in 4 major Indonesian tribes to produce 250 abusive words for hate speech detection using the lexicon-based approach.
