Abstract

Accurate fertile-infertile egg classification is crucial to improve hatching productivity and sorting efficiency. This study proposes MobileFusionV3, a MobileNetV3 architecture enriched with CBAM (Convolutional Block Attention Module) and Hybrid Texture Fusion (LBP and GLCM) to combine deep and texture features to be more robust to candling illumination variations. A dataset of 1,275 candling images (675 fertile, 600 infertile) was subjected to preprocessing (resizing, normalization, background enhancement) and realistic data augmentation (rotation, brightness/contrast changes, Gaussian noise, illumination variations). The model was trained using transfer learning, early stopping, and an evaluation scheme based on accuracy, precision, recall, F1-score, and AUC. The test results showed an accuracy of 97.2%, precision of 96.8%, recall of 97.5%, F1 of 97.1%, and AUC of 0.99, surpassing previous designs that did not use attention mechanisms and texture fusion. Grad-CAM++ analysis confirms the model's focus on physiologically relevant regions (embryonic shadow and air-cell), thus improving the reliability of interpretation. These findings indicate that lightweight, efficient designs based on attention and texture fusion have the potential to be implemented in smart hatchery systems and edge/mobile devices while maintaining high accuracy.

Abstract

Improving the competitiveness of local products in the digital era requires micro, small, and medium enterprises (MSMEs) to be able to utilize information technology in their marketing processes. However, many local business actors still rely on conventional promotional methods and have not yet optimized the use of digital media. This Community Service Program (PKM) aims to assist partner MSMEs in increasing their product visibility through website creation and social media management as promotional tools. The program was carried out in several stages: identifying partner needs, training in the creation and management of websites using WordPress, training in content design and marketing strategies via social media (Instagram, Facebook, and WhatsApp Business), and mentoring in content creation and account management. During the program, partners were equipped with basic skills to build a simple online store website, copywriting techniques, product photography using smartphones, and the use of free design tools such as Canva. The results of the activity show that partners who previously had no online presence now have active websites displaying product catalogs, business profiles, and contact information. In addition, the partners’ social media accounts became more active and strategically managed, featuring consistent and engaging promotional content. This activity also increased partners’ understanding of the importance of digital identity and content-based marketing strategies. The PKM provided direct impact in the form of increased consumer trust in local brands, enhanced sales potential, and better preparedness of MSMEs to compete in the digital market. Moving forward, this training can be replicated in various local business communities as part of a technology-based community economic empowerment effort.

Abstract

SQL Injection (SQLi) attacks are a major threat to web application security, with attackers frequently attempting to modify query patterns repeatedly to evade detection. This research aims to develop a method for detecting repeated SQL Injection attacks in Apache logs using a semantic embedding approach. The method employed includes preprocessing log data using Natural Language Processing (NLP) techniques, generating vector representations through semantic embedding, and classifying using machine learning algorithms. The novelty of this research lies in the application of semantic embedding on Apache log queries to identify recurring and polymorphic SQL Injection attacks based on contextual similarity rather than exact syntactic matching. Experimental results show that the Support Vector Machine (SVM) model achieved the best performance with an accuracy of 94.5%, precision of 92.0%, recall of 91.0%, and F1-score of 91.5%, outperforming conventional rule-based detection methods.. The results show that the proposed approach is capable of recognizing semantic similarities between queries despite syntactic differences, thereby improving detection accuracy and reducing false positive rates compared to rule-based methods. Therefore, this method is effective for large-scale log analysis and is capable of detecting repeated and polymorphic SQL Injection attack pattern in web application environments.

Abstract

Digital transformation in higher education is driving the uptake of online tests, which require academic integrity, security, and robust user experience. In the context of authentication of users, deep learning based face recognition, in particular the Convolutional Neural Network (CNN) architectures, such as MobileNetV2, combined with intermediate filter, promises to deliver a consistent performance across a wide range of devices and imaging environments. However, there are limited comprehensive studies evaluating the final integration of the median filter and MobileNetV2 in high-value test scenarios. This study contributes by proposing an effective end-to-end Face Authentication Pipeline, assessing the median impact of filtering on MobileNetV2 performance, and validating it with a prototype application. The authentic face dataset was collected using the Teachable Machine, preprocessed with cropping, resizing, and median filtering, and then augmented through rotation, shift, shear, zoom, reversal, and brightness adjustment. The MobileNetV2 model was trained with Adam in a stepwise manner, starting with 0.001 and then 0.0001 for 20 epochs in a batch size of 32, and was evaluated for accuracy, precision, recall, and F1 score. Results show that the accuracy curve has remained stable at almost 95 percent during the 20th epoch; most grades achieved 1.00 in both precis, recall and F1, with some classings showing a limited decrease due to facial similarity or expression differences. These findings confirm that MobileNetV2 median filtering can be the basis for an effective, accurate and ready to integrate face recognition in online testing applications on a wide range of devices.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) play a vital role in strengthening the national economy; however, many still face challenges in managing and analyzing sales data effectively. This study aims to classify product sales results at UMKM Kangen Kripik Mang Acep by applying the Decision Tree algorithm as a data classification method based on machine learning. A quantitative experimental approach was employed to evaluate the model’s performance using one-year sales data, including attributes such as product variants, sales volume, sales channels, and marketing regions. Data processing was conducted using RapidMiner software following the Knowledge Discovery in Databases (KDD) framework, which includes data selection, preprocessing, transformation, data mining, and model evaluation. The results indicate that the Decision Tree algorithm successfully classified sales regions (Garut, Bandung, and Sumedang) with an accuracy rate of 96.48%, identifying “Units Sold (pcs)” as the most influential attribute for distinguishing marketing areas. These findings demonstrate that the Decision Tree method is not only effective in improving data analysis efficiency but also provides valuable strategic insights for data-driven business decision-making in MSMEs
