Abstract

Heart disease remains a leading cause of mortality worldwide, including in Indonesia, and is often difficult to detect at an early stage. One of the main challenges in the Indonesian healthcare system is the lack of fully digitalized data management and the issue of imbalanced patient datasets, which reduce classification accuracy. This study developed a web-based information system designed to manage patient records and automatically classify heart disease risk. The system was implemented using the CodeIgniter framework with a MySQL database, and applied an Artificial Neural Network (ANN) in combination with the Synthetic Minority Over-sampling Technique (SMOTE) to address data imbalance. A total of 60 secondary patient records were processed through preprocessing, data balancing, model training, and cross-validation. Experimental results demonstrated that the application of SMOTE improved model sensitivity, with performance metrics of 87.4% accuracy, 85.2% precision, 88.6% recall, and an AUC-ROC of 0.94. These findings confirm that integrating ANN and SMOTE into a web-based system enhances classification reliability and supports faster medical decision-making. However, the study also acknowledges certain limitations, including the restricted dataset size and the absence of validation in real clinical environments. Future work should expand the dataset, test the system in healthcare facilities, and compare performance with other algorithms such as Random Forest or SVM to identify the most optimal predictive model.

Abstract

This research introduces a mobile-based system for real-time identification of ornamental rose varieties using the YOLOv8 deep learning algorithm. Motivated by the growing interest in ornamental plants during the COVID-19 pandemic and the high penetration of smartphone users in Indonesia, the study aims to create an efficient and accessible flower recognition tool. A dataset of 813 labeled rose images—red, white, yellow, orange, and pink—was collected from the Roboflow platform and processed using data augmentation techniques to improve model generalization. The YOLOv8 model was trained with 100 epochs, a batch size of 16, and the SGD optimizer, then converted to TensorFlow Lite for mobile deployment through the Flutter framework. Experimental results achieved a mean average precision (mAP50–95) of 0.581, with strong detection performance across most classes. The system successfully operated offline, delivering real-time classification accuracy despite dataset imbalance, particularly in the orange rose class. These findings demonstrate that YOLOv8 can be effectively adapted for mobile horticultural applications, offering practical benefits for flower sorting, crop management, and educational use. Future studies are recommended to expand dataset diversity, enhance environmental testing, and explore cloud-based integration for scalable deployment.

Abstract

system pengolahan File data (RT)  dengan organisasi kependudukan yang diatur sebuah negara yang memakai peraturan mendasarkan sebuah daerah di desa atau di kota yang ada di Indonesia. Organisasi Rukun Tangga (RT) berfungsi menambahkan aktifitas, bentuk pelayanan, kesejahteraan, dan partisipasi masyarakat. RT juga sebuah organisasi tingkat bawah dan sangat dekat dengan masyarakat serta memahami semua kondisi dan permasalahan yang dihadapi masyarakat di daerah dalam pemerintahan RT tersebut. Hal ini sangat sering terjadi secara umum di daerah kekuasaan  Ketua RT 004 masih menggunakan system manual  dengan pencatatan dikertas atau sebuah buka secara tradisional ,sehingga pengolahan pemberitahuan informasi ke pada masyarakat tidak terlalu efektif. dalam masalah yang ada maka kami melakukan sebuah penelitian. Penelitian ini bertujuan untuk membantu memajukan proses system pengolahan data lebih cepat ,dengan Web Apk/Aplikasi RT 004 Berbasis Web. Penelitian dilakukan dalam tahap-tahap: identifikasi/pengenalan masalah, proses pendataan data, studi literature, dan mempercepat proses sistem dengan menggunakan metode  mudah yaitu Waterfall, lalu dengan tahap berurutan: Penerimaan, Update fitur, implementation, verification dan maintance. Dengan adanya web Apk ini Ketua RT 004 serta Staf tidak harus lagi menggunakan cara tradisional dalam proses pendataan ataupun mengnge cek data penduduk yang selama ini masih menggunakan kertas.
