Abstract

Pertumbuhan kendaraan di wilayah perkotaan menimbulkan permasalahan keterbatasan lahan parkir dan waktu pencarian tempat parkir yang lama. Penelitian ini bertujuan untuk merancang dan menerapkan sistem yang dapat secara otomatis mendeteksi dan memantau ketersediaan lahan parkir dengan memanfaatkan algoritma YOLOv5 serta citra yang diambil dari kamera drone. Metode yang digunakan mencakup akuisisi data citra melalui rekaman drone dari dua sudut pandang berbeda (atas dan samping), pelabelan data, pelatihan model deteksi objek, serta klasifikasi status slot parkir (kosong atau terisi). Evaluasi sistem dilakukan dengan mengukur precision, recall, accuracy, dan mAP@0.5. Hasil pengujian menunjukkan bahwa sudut pandang memengaruhi akurasi deteksi: pada sudut pandang samping, sistem memperoleh precision 100%, recall 75,86%, dan mAP@0.5 sebesar 75,86%, sedangkan pada sudut atas recall dan mAP@0.5 turun menjadi 35,29% dan 35,00%. Visualisasi Confusion Matrix dan Precision-Recall Curve mendukung hasil ini. Sistem yang dibangun terbukti mampu mendeteksi dan memantau ketersediaan lahan parkir secara real-time dengan visualisasi pada dashboard digital. Pemanfaatan kamera drone memberikan kemampuan untuk menjangkau area yang lebih luas dan fleksibel dibandingkan dengan penggunaan kamera statis. Dengan demikian, sistem ini memiliki potensi untuk menjadi solusi praktis dalam pengembangan smart parking berbasis deep learning di ruang publik.

Abstract

Digital transformation has posed new challenges for retail companies in understanding consumer behavior due to the increasing volume of data and continuously changing preferences. This study aims to uncover purchasing patterns among retail customers and to provide data-driven marketing strategies through customer segmentation using the K-Means Clustering algorithm. This research adopts a quantitative exploratory approach using 3,900 synthetic entries from the Kaggle platform, representing retail transactions. The analysis focuses on variables such as age, gender, product category, location, purchase amount, and transaction frequency. The analytical process includes data preprocessing, dimensionality reduction using PCA, and segmentation with the K-Means algorithm. The optimal number of clusters was determined using the Elbow Method and Silhouette Score, while the quality of the clustering was evaluated using internal metrics, namely the Calinski-Harabasz Score (491.47) and the Davies-Bouldin Score (2.02). These values indicate a well-structured and reliable clustering result. Our findings reveal five distinct customer segments with varying characteristics, ranging from teenagers with small and periodic purchases to high-value adult customers who transact infrequently. These insights serve as the foundation for developing marketing strategies such as loyalty programs, seasonal promotions, and exclusive approaches.

Abstract

Manual fruit sorting typically relies on workers' visual observation to assess ripeness. This assessment is heavily influenced by individual experience and lighting conditions, often leading to inaccuracies. Furthermore, manual methods are time-consuming, increase the risk of misclassification, and reduce operational efficiency. Our research aims to develop a color-based Fuji apple ripeness classification application using the K-Nearest Neighbor algorithm that combines RGB and HSV features. Our research is developmental research using the Waterfall model, consisting of requirements analysis, design, implementation, testing, and maintenance. We used 240 fuji apple images sourced from images taken in the Kudus area. Our findings are an automatic classification application capable of classifying apple images into three ripeness levels: unripe, semi-ripe, and ripe. The evaluation results showed an accuracy of 93.75% with balanced precision, recall, and f1-score across all classes, confirming the system's stable performance without any indication of bias. Testing results using the black-box method in three scenarios opening the application, uploading an image, and reclassifying proved that all features performed as expected. The implication is that this application is ready for use in camera-based sorting in horticultural production lines and can be developed for other fruit classifications, supporting widespread post-harvest digitalization.

Abstract

Traffic congestion caused by the rapid increase in motor vehicles without proportional infrastructure development demands a more efficient and accurate vehicle identification system. One crucial component is the Vehicle Registration Number (TNKB), which serves as the official identifier. License Plate Recognition (LPR) technology provides a Smart Mobility solution that enables automatic reading of TNKB from digital images. This study aims to develop an automatic license plate recognition system in the "K" region of Kudus City using YOLO object detection and EasyOCR-based Optical Character Recognition (OCR). YOLO is used to detect license plate regions in both images and video in real time, while OCR is applied to recognize the characters. Previous studies have shown that YOLOv4 and YOLOv8 models achieve detection accuracies above 90% and can operate on low-resource devices under poor lighting conditions. This system is expected to improve the efficiency of vehicle data recording, reduce manual errors, and support the integration of smarter transportation systems. In conclusion, the implementation of LPR using YOLO and OCR shows strong potential for application in local traffic environments such as Kudus City.

Abstract

Urban traffic congestion is a persistent issue in medium-sized cities like Demak, leading to delays and potential accidents. This study presents the development of a real-time vehicle density and anomaly detection system using YOLOv8, combined with OpenCV for video analysis, to monitor traffic flow at strategic entry points of Demak City. The system classifies vehicles into four categories (cars, motorcycles, trucks, buses) and determines their direction by detecting crossing lines. A key feature is the recognition of vehicle patterns, particularly the detection of stopped vehicles, flagging anomalies after 30 seconds of stoppage, with tolerance for temporary detection losses. Traffic data is stored in CSV format, enabling periodic analysis and visualization via an interactive graphical user interface (GUI). Evaluation results show the YOLOv8n model achieves 92.5% precision, 88.3% recall, and 89.7% mean average precision (mAP@0.5), demonstrating improved accuracy and speed over previous YOLO versions. Additionally, the vehicle counting accuracy reaches 94.2% when compared with manual annotations. The proposed system provides a reliable solution for real-time traffic monitoring and early anomaly detection, supporting intelligent transportation systems (ITS) and enabling data-driven traffic management decisions. This research contributes to the advancement of real-time video analytics and pattern recognition for urban traffic control and serves as a scientific reference for the development of smart city infrastructures. Furthermore, this study strengthens the application of pattern recognition in intelligent anomaly detection, providing new insights for researchers in the fields of computer science and informatics.

Abstract

The increasing popularity of digital reading platforms in Indonesia, such as Fizzo Novel, has generated many user reviews that can be analyzed to understand their satisfaction. This study analyzes user sentiment toward Fizzo Novel using the SEMMA (Sample, Explore, Modify, Model, Assess) framework, and compares the performance of the Support Vector Machine (SVM) and Naïve Bayes algorithms. A total of 139,759 reviews were collected from the Google Play Store through web scraping. The data was then processed through normalization, tokenization, lexicon-based sentiment labeling, and feature extraction using TF-IDF. To address class imbalance, the SMOTE technique was applied. The results showed that SVM achieved the highest accuracy, exceeding 96%, with a consistent F1-score across all sentiment classes. In contrast, Naïve Bayes recorded lower accuracy (75.82% before SMOTE and 73.63% after SMOTE), along with a decline in performance for the neutral class. SVM proved more reliable in handling large and imbalanced text data. Practically, the results of this study can help application developers such as Fizzo Novel in automatically understanding user opinions. With an accurate sentiment classification model, developers can monitor reviews in real-time, identify issues such as excessive advertising or an unpopular chapter division system, and design feature improvements based on real user needs. This research also provides a foundation for algorithm selection in future large-scale sentiment analysis projects and recommends SVM as the more appropriate choice in this context.
