Abstract

This research presents the development of a real-time attendance system utilizing facial recognition, which incorporates three main components: the MobileNet Convolutional Neural Network (CNN) for classification, Multi-task Cascaded Convolutional Networks (MTCNN) for face detection, and Contrast Limited Adaptive Histogram Equalization (CLAHE) for image preprocessing. The model was trained on a curated subset of the Labeled Faces in the Wild (LFW) dataset, containing 20 categories with 50 images each, and evaluated using a locally captured dataset. Training was conducted on Google Colab using a pre-trained MobileNet model that was fine-tuned with 800 images, while 200 images were used for validation. System performance was assessed through several metrics, including accuracy, precision, recall, F1-score, and a confusion matrix. The model achieved a validation accuracy of 86% and an average F1-score of 0.85, reflecting high classification accuracy. To enhance usability, the system was implemented within a Python-based graphical user interface (GUI), which automates attendance tracking and records data directly into Excel spreadsheets. This study highlights the potential of integrating lightweight CNN architectures with effective preprocessing techniques and real-time GUI applications to create a reliable, efficient, and practical biometric attendance system

Abstract

Shopee is one of the most popular online marketplaces in Indonesia, with more than 103 million users in 2023. Most users consider factors such as customer reviews, ratings, prices, and free shipping promotions before making a purchase. Analyzing user reviews is essential to understand consumer perceptions of services, identify satisfaction or dissatisfaction, and detect potential issues that need to be addressed. However, sentiment analysis faces challenges in processing text with diverse language styles, structures, and informal expressions. To overcome these challenges, this study applies machine learning algorithms—Support Vector Machine (SVM) and K-Nearest Neighbors (KNN)—for classifying sentiment in Shopee user reviews. Data labeling using the Lexicon InSet method produced 9,509 positive reviews (47.55%), 7,686 negative reviews (38.43%), and 2,805 neutral reviews (14.03%). Based on the Confusion Matrix results, SVM outperformed KNN, particularly in classifying negative and neutral sentiments with higher accuracy. These findings indicate that SVM is a more effective and efficient model for sentiment analysis of user reviews on the Shopee platform.

Abstract

Spices and herbs are biological resources that have long played an important role in human life. In the current pandemic where our bodies have an immune system that can manage the body's power, but the factors of age, lifestyle and regular use of drugs can affect the level of body power, therefore this spice has been considered to provide health and this has led to the demand for spices. high enough. The continuous use of spices, both from the household sector to the industrial sector, makes consumers have to find or buy these spices every day to the market or to spice collectors for industrial consumers. To meet market needs and consumer needs directly, therefore the proposed solution to overcome this problem is to use e-commerce media. The system development model used in making this information system is the SDCL (System Development Life Cycle) waterfall (Waterfall) or classic life flow. The stages that are passed in the system analysis and design process include: system requirements analysis, design, code generator, testing and support. From the results of this study, it is hoped that the existence of this spice sales information system can help farmers, especially spice producers, in terms of increasing the selling power of their agriculture, making it easier to carry out promotions, sales transactions to produce sales reports.
