Abstract

This study aimed to classify the nominal value of Rupiah banknotes using image processing and classification methods. The research design was conducted by collecting a dataset of Rupiah banknotes consisting of 30 classes, each with 100 images. This research uses image preprocessing by using Canny Segmentation to create the edges of objects and clarify image details. The Hu Moments method, which describes the pixel distribution and shape of objects, was used to extract special features from images. Furthermore, classification modeling was carried out with Decision Tree and Random Forest to classify banknotes based on extracted characteristics. Model evaluation was carried out by measuring accuracy, precision, recall and f1-score performance and using cross-validation with k-fold = 5. The results showed that the Random Forest method was able to classify Rupiah banknotes well. In performance evaluation, the Random Forest method achieved an accuracy of 0.93 and good precision, recall, and f1-score scores for several banknote classes. The Decision Tree method also achieved good results, with an accuracy of 0.86. The results of the classification evaluation showed that the Random Forest method was better than the Decision Tree in classifying the banknotes.

Abstract

This study explores the application of a Random Forest Classifier for the automated detection of Cardiomegaly from chest X-ray images, utilizing a dataset processed and derived from the NIH Chest X-ray Dataset. Given the crucial need for accurate and timely diagnosis of Cardiomegaly to inform appropriate treatment decisions, this research aims to determine the efficacy of machine learning models in augmenting diagnostic processes. Employing image pre-processing techniques such as Sobel filtering for edge detection and Hu Moments for feature extraction, the study enhances the input features for the model. The performance of the classifier was evaluated using a 5-fold cross-validation approach, yielding results with average accuracy, precision, recall, and F1-scores ranging approximately between 52% and 54%. These findings suggest a moderate level of reliability and consistency, indicating the potential utility of ensemble machine learning methods in medical imaging analysis. However, the variability in performance across different data subsets highlights the challenges and necessitates further optimization. This research contributes to the ongoing discourse on integrating machine learning into clinical settings, demonstrating the potential benefits and current limitations. Future research is recommended to expand the dataset variety, integrate advanced deep learning methodologies, and rigorously test these models in clinical environments. The findings hold significant implications for the development of automated diagnostic tools in healthcare, potentially leading to enhanced diagnostic accuracy and efficiency.

Abstract

Banyak upaya yang dapat dilakukan untuk membantu proses pembelajaran. Transfer pengetahuan akan optimal jika didukung dengan media pembelajaran yang tepat. Sekolah Dasar Inpres Marinding dalam proses pembelajaran selama ini belum dapat memanfaatkan teknologi terkini yang sesuai untuk meningkatkan pemahaman siswa tentang suatu mata pelajaran. Padahal pesatnya perkembangan teknologi informasi dapat dimanfaatkan sebagai media tambahan untuk mendukung pembelajaran yang merangsang imajinasi, interaktif dan menumbuhkan minat belajar sehingga proses belajar mengajar menjadi lebih baik lagi.Demi menunjang proses pembelajaran di SDN 294 Inpres Marinding, siswa diharapkan memiliki banyak buku yang berisi satu tema tertentu sebanyak jumlah tema yang ada. Akan tetapi, pembelajaran masih berpusat pada buku tersebut dan tidak ada alat peraga khusus tentang Flora. Siswa tidak dapat melihat objek Flora secara langsung, hanya melalui gambar di buku dan kurang detailnya informasi tentang objek tersebut. Akibatnya, pembelajaran cenderung monoton, dan kurang kreatifitas.Solusi yang diusulkan adalah memberikan pelatihan untuk implementasi aplikasi Augmented Reality Pengenalan dengan tujuan untuk meningkatkan pengetahuan guru dan siswa dalam pemanfaatan teknologi informasi untuk media pembelajaran alternatif melalui Augmented Reality khususnya pembelajaran Flora.Tercapainya tujuan kegiatan telah menghasilkan luaran berupa modul dan aplikasi yang dapat menjadi alternatif media pembelajaran, publikasi pada media online dan jurnal yang diterbitkan di ILKOMAS.
