Abstract

Identification of the size of the evidence file conversation can be one of the tools for various purposes such as in the police world. Determining the class of the room from the recording can be an additional clue in case processing.  One way for the police to identify the class of a room is by creating a room class detection system. The class of the room can be determined by measuring the reverberation time using the LPC algorithm by extracting the characteristics of the training data in the form of audio. After obtaining the characteristics, the system will store these characteristics in the form of a dataset for testing. Then, the test data for which the room class is not yet known is inputted into the test system. KNN will classify the test data based on the previously trained dataset. The last process of the system will issue the value of accuracy and computational time from system testing. This study uses MATLAB calculation software as a calculation and simulation process, using 63 training data and 18 test data.  The  accuracy of  the  system  test  for detecting room class based on reverberation time using the LPC and KNN methods has resulted in a number with the largest accuracy value of 83.33% and computation time along 4,94657 seconds with a K value of 3, LPC order of 12, number of frames 240, and the Hanning window.

Abstract

Breast cancer remains one of the leading causes of cancer-related deaths worldwide, highlighting the need for accurate and efficient diagnostic tools. This study focuses on implementing machine learning models, particularly Artificial Neural Networks (ANN), to classify breast cancer types based on genomic data. Using the METABRIC RNA Mutation dataset, the system combines a cloud-based backend with Supabase and an intuitive frontend built with Streamlit. To ensure data compatibility with the models, preprocessing steps such as standardization, label encoding, and one-hot encoding are applied. TensorFlow is used to load models saved in .h5 format, with two approaches tested: a 30-feature model achieving 99% accuracy and an average prediction time of 80 milliseconds, and a 6-feature model achieving 100% accuracy with a faster prediction time of 42.25 milliseconds. Prediction results are stored securely in Supabase, complete with timestamps for tracking and exported as PDF reports for easy documentation. Data security is prioritized through the use of API keys, JWT tokens, and Streamlit secret management to safeguard sensitive information. The integration of Supabase for backend processing, Streamlit for real-time visualization, and GitHub for CI/CD automation results in a scalable, reliable, and efficient system. This study presents a robust solution for breast cancer classification, providing real-time predictions, secure data handling, and a user-friendly interface suitable for clinical and research applications. Keywords— breast cancer classification, artificial neural network, genomic data, Supabase, Streamlit, real-time prediction, data security.

Abstract

Cyberbullying merupakan fenomena sosial yang se- makin meningkat seiring dengan meningkatnya penggunaan media sosial, dan seringkali menyebabkan dampak psikologis serta emosional yang merugikan, terutama melalui hate com- ments. Penelitian ini bertujuan untuk mengevaluasi kinerja model IndoBERT dan Cendol dalam mendeteksi komentar kebencian yang berhubungan dengan cyberbullying. Survei terhadap 328 partisipan menghasilkan 64 kata kunci terkait cyberbullying. Proses penelitian mencakup pengumpulan dataset yang berisi kata kunci tersebut, serta pengujian kedua model menggunakan metrik evaluasi seperti akurasi, presisi, recall, dan F1-Score. Hasil eksperimen menunjukkan bahwa model Cendol unggul dengan akurasi sebesar 90,5% pada konfigurasi batch size 15, epoch ke-4, dan learning rate 10-3, sementara IndoBERT hanya mencapai akurasi 36% pada konfigurasi batch size 5, epoch ke- 4, dan learning rate 10-3. Meskipun kedua model menunjukkan potensi dalam mendeteksi ujaran kebencian, model IndoBERT menunjukkan performa yang lebih rendah pada dataset yang digunakan, kemungkinan disebabkan oleh keterbatasan dalam menangani konteks lokal. Penelitian ini memberikan kontribusi signifikan dalam pengembangan teknologi deteksi ujaran keben- cian berbasis bahasa Indonesia, yang dapat diimplementasikan pada berbagai platform media sosial seperti X, Facebook, Insta- gram, dan TikTok untuk mengurangi dampak negatif dari hate comments. Kata Kunci: Cyberbullying, Hate Comments, IndoBERT, Cen- dol, NLP.
