Abstract

Stunting is a condition where growth and development of children under 5 years of age is impaired due to chronic malnutrition. Data mining with classification techniques on the nutritional status of stunting toddlers can be performed to help identify toddlers experiencing stunting and provide objective measurements of their nutritional status. There are several classification methods, but this research will compare the performance of the C4.5 decision tree algorithm, which is included in the decision tree approach, and naive Bayes, which uses a probability-based approach of class occurrence in classifying nutritional status of stunting toddlers, with discretization performed in the preprocessing stage. The data used in this research was obtained from Jagir Health Center, Surabaya, in the form of secondary data on toddler nutrition in 2021, totaling 2,801 records. The labeling of stunting or normal in the dataset uses the reference of child anthropometric standards in Indonesia as stated in the Republic of Indonesia Minister of Health Regulation number 2 of 2020. The best method based on the AUC (Area Under the Curve) value was the C4.5 decision tree with a value of 86% (good classification), while naive Bayes achieved 77% (fair classification) using a 70:30 training and testing data ratio.

Abstract

The management of incoming and outgoing correspondence in government institutions such as the Palesanggar Village Office is still carried out manually, leading to various problems such as delayed recording, difficulty in retrieving archived letters, and potential data loss. This study aims to develop a web-based Incoming and Outgoing Mail Information System to improve administrative efficiency and facilitate the archiving and reporting processes. Data were collected through direct observation, interviews with village officials, and literature review. The system development method used in this research is the Agile model, which consists of requirement analysis, system design, implementation, and testing phases. The result of this study is a web-based information system capable of recording, storing, and displaying data on incoming and outgoing letters in a structured manner and accessible to village staff. System testing shows that the application functions properly and is well received by users. The conclusion of this research is that the developed information system successfully addresses the issues of manual mail management and provides convenience and speed in archiving letter data at the Palesanggar Village Office.

Abstract

Prediksi harga saham berperan penting meminimalisir kerugian akibat fluktuasi harga saham. Penelitian ini bertujuan untuk meningkatkan akurasi prediksi harga saham PT Aneka Tambang Tbk (ANTM) menggunakan model Gated Recurrent Unit (GRU) dengan optimasi hyperparameter melalui metode Grid Search. Model GRU dipilih karena mampu mengatasi permasalahan vanishing gradient dan efektif dalam mempelajari pola ketergantungan jangka panjang pada data deret waktu walaupun dengan arsitektur yang sederhana. Sementara itu, Grid Search digunakan karena memiliki keunggulan dalam menjelajahi ruang hyperparameter secara menyeluruh, sehingga setiap kombinasi parameter dapat diuji dan memungkinkan diperolehnya konfigurasi terbaik. Proses Grid Search dilakukan dengan ruang pencarian hyperparameter yang mencakup jumlah units, jumlah epoch, ukuran batch, serta variasi optimizer. Keunggulan utama penelitian ini terletak pada penerapan optimasi hyperparameter yang mampu meningkatkan efektivitas model GRU dalam menemukan konfigurasi terbaik, sehingga menghasilkan prediksi harga saham yang lebih akurat dan stabil. Evaluasi kinerja model menggunakan metrik RMSE, MAE, MAPE. Hasil penelitian menunjukkan bahwa model GRU dengan optimasi Grid Search menggunakan optimizer Adam memberikan performa yang optimal dengan nilai evaluasi RMSE sebesar 67.8805, MAE sebesar 45.6501, dan MAPE sebesar 2.2309%. Temuan ini membuktikan bahwa optimasi hyperparameter melalui Grid Search mampu meningkatkan akurasi prediksi model GRU pada data harga saham.

Abstract

Integrity and honesty are fundamental aspects of education, including the implementation of the Computer-Based Written Examination (UTBK). Conventional exam supervision is considered less effective in monitoring participants’ behavior due to the limitations in human observation capabilities and consistency. This study develops a real-time cheating-detection system based on camera input by integrating the YOLOv8 algorithm with Farnebäck optical flow. The YOLOv8 algorithm identifies participants’ body poses and activities directly from video footage, while Optical Flow analyzes the direction and motion patterns between frames over time. The system is designed to recognize various suspicious poses such as head-turning, bowing, and cheating-related gestures that indicate potential dishonesty. All detection results are automatically recorded in an SQLite database, complete with timestamps and visual evidence. Experimental results show that the system achieves 94.3% accuracy in detecting suspicious movements. The combination of both methods also helps maintain detection stability when keypoints are not consistently captured in some frames. Additionally, the system is equipped with a graphical user interface (GUI) to facilitate easier monitoring and analysis. These results demonstrate that a pose-and-motion analysis-based approach offers an intelligent and efficient solution for enhancing digital supervision of UTBK examinations.

Abstract

Keamanan informasi merupakan aspek penting dalam penerapan sistem layanan berbasis teknologi informasi di lingkungan perguruan tinggi. Sistem layanan UPA PKK UPN Veteran Jawa Timur berperan dalam mendukung kegiatan pengembangan karier dan kewirausahaan mahasiswa serta alumni sehingga memerlukan pengelolaan risiko keamanan informasi yang terstruktur. Penelitian ini bertujuan untuk menganalisis risiko keamanan informasi menggunakan metode NIST SP 800-30. Tahapan penelitian meliputi identifikasi ancaman, identifikasi kerentanan, analisis pengendalian, penilaian tingkat kemungkinan dan dampak, serta penentuan tingkat risiko. Hasil penelitian menunjukkan bahwa risiko keamanan informasi pada sistem layanan UPA PKK berada pada kategori rendah, sedang, hingga tinggi, dengan risiko dominan berada pada tingkat sedang hingga tinggi, terutama pada aspek keamanan akses sistem dan pengelolaan data. Rekomendasi pengendalian difokuskan pada penguatan mekanisme autentikasi, pembaruan sistem secara berkala, serta peningkatan prosedur keamanan. Metode NIST SP 800-30 terbukti memberikan pendekatan yang sistematis dalam pengelolaan risiko keamanan informasi pada sistem layanan UPA PKK.

Abstract

Cancer is one of the deadliest diseases in the world. This is because patients often do not realize the presence of cancer in their bodies, leading to delayed treatment and the cancer becoming aggressive. Early diagnosis of cancer in women is necessary since the majority of cancer patients are women. One of the markers that can be used to diagnose cancer is the anti-Mullerian hormone, accompanied by other indicators such as lifestyle, BMI, and others. Early diagnosis can utilize the Multi-Layer Perceptron (MLP) algorithm, which is currently a rapidly developing technology. By using the MLP algorithm, an accuracy of 84% is achieved on the training data and test data, with a training-to-testing data ratio of 65:35.
