Abstract

Algoritma A* yaitu salah satu algoritma untuk mencari rute yang komplit dan optimal. Algoritma A* menggabungkan nilai g(n) dan h(n) untuk mencari bobot terendah dalam menemukan Solusi. Di Indonesia, terutama di kota-kota besar maupun Kawasan tempat orang-orang bekerja, salah satunya di PT Yamaha Music mengalami beberapa kendala seperti kemacetan. Selain itu, pengendara cenderung memakai jalur alternatif untuk dapat mencapai tujuannya dengan cepat. Pada penelitian ini, dibuat system yang dapat menentukan rute alternatif untuk para pengendara. Penelitian ini menggunakan metode Algoritma A* yang dapat menentukan rute secara optimal. Penelitian ini juga menggunakan nilai heuristic yang digunakan sebagai dasar pertimbangan. Heuristic adalah kriteria metode atau prinsip untuk menentukan pilihan sejumlah alternatif untuk mencapai tujuan dengan efektif dengan menggunakan nilai g(x). Maka dari hasil penelitian dapat menghindari kemacetan dengan rute yang efektif.

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.
