Abstract

The COVID-19 pandemic has increased inflation and poverty rates in many cities, thus requiring considerable attention from the government as a policymaker. Therefore, this study aims to cluster regencies/cities that need mitigation priorities from the Indonesian government based on inflation and poverty rates in 2021. Four machine learning methods, namely k-Means (KM), Partitioning around medoids (PAM), Ward, and Divisive analysis (Diana) are utilized and compared to achieve that purpose. Clustering 90 regencies/cities in Indonesia produced five optimal clusters. Furthermore, the clustering results were validated using the Silhouette width (SW) and Dunn index (DI). The results showed that the k-means method produced the most compact cluster. Hence, this study's results can be utilized as a reference for the government in determining the steps and priorities of economic policy in Indonesia.

Abstract

Manual assessment of coconut ripeness is often subjective and causes post-harvest losses of up to 25% in Indonesia, the world's largest coconut producer. This study aims to develop a CNN VGG-19 model for automatic classification of three ripeness levels (immature, medium, mature) with accuracy >95%. The quantitative experimental method uses supervised learning with a dataset of 900 original images (300/class) from local plantations in South Sumatra, augmented to 3000 images. Instruments include Python/TensorFlow on Google Colab, preprocessing (rembg background removal, resizing 224x224), training 10 epochs of the Adam optimizer. Analysis uses a confusion matrix, accuracy, precision, recall, and F1-score. The results show a progressive accuracy from 14% (40 test data/class) to 98% (200 test data/class). Conclusion: VGG-19 transfer learning with data augmentation is effective for local coconut ripeness classification, potentially integrating into mobile applications for the processing industry.

Abstract

Advances in image processing and deep learning technology enable more accurate handwriting analysis, including the detection of interword spacing, which exhibits high complexity due to variations in writing styles. This study aims to implement a Convolutional Neural Network (CNN) algorithm using the You Only Look Once version 11 (YOLOv11) framework to detect and classify interword spacing zones into three classes: Narrow Word Spacing (NWS), Medium Word Spacing (MWS), and Wide Word Spacing (WWS). The dataset comprises 150 handwritten images with a total of 4.117 annotated interword spacing objects. The research methodology involves testing the model across variations of learning rates (0.1, 0.01, 0.001, and 0.0001) and data split ratios (70:30, 80:20, and 90:10). Model performance was evaluated using Precision, Recall, F1-Score, and mean Average Precision (mAP) metrics. Based on 12 experimental trials, the best configuration was achieved with a learning rate of 0.001 and a 90:10 data split. This configuration produced an mAP@50 of 0.455, an mAP@50–95 of 0.261, and an F1-Score of 0.49. These results indicate that the YOLOv11 model is capable of detecting interword spacing zones with reasonably good performance, despite remaining classification errors due to visual similarities between classes.

Abstract

Manually identifying graduates can slow down the procession and increase the risk of misidentification. This study evaluates a real-time facial recognition system using VGG-Face for feature extraction and Cosine Distance for matching. Faces are detected using OpenCV's Haar Cascade and represented as 4096-dimensional embeddings via the VGG-Face model (accessed through DeepFace). Identity is determined based on the minimum Cosine Distance value using a 0.6 threshold and validated by consistent detection across three consecutive frames. Testing involved 20 individuals (10 registered graduates and 10 unregistered individuals) across four conditions: distances of 50 cm, 100 cm, and 100–150 cm, as well as a 50 cm distance with the subject wearing glasses. Out of 885 recorded recognition events, the results yielded 416 True Positive s, 440 True Negatives, 22 false Positive s, and 7 false Negatives. Evaluation metrics showed an accuracy  of 96.7232%, precision of 94.9772%, recall of 98.3452%, and an F1-score of 96.6318%. The average system latency was 0.6877 seconds. For the registered group, varying the distance up to 150 cm resulted in minimal changes to the recognition rate, whereas wearing glasses reduced the recognition rate to 95%. The findings indicate that the system supports rapid graduate identification in semi-controlled environments, however, the rejection of unregistered faces and robustness against occlusion require further improvement.
