Abstract

Image-based malware detection has become an area of further research in dealing with image-based malware attacks. Various deep learning models have been used to improve detection accuracy. One popular architecture is VGG16, a convolutional network widely used in image classification. In this study, we explore the impact of hyperparameter tuning on the optimization of the VGG16 model for image-based malware detection. The hyperparameter experiments conducted in this study are optimizer, and the number of epochs. Through 6 experiments with parameter variations, we evaluate the performance of the VGG16 model using several SGD, and Adam optimizers and the number of epochs consisting of 100, 250 and 500 epochs. The experimental results show that the selection and tuning of the optimizer can affect the performance of the model in terms of accuracy and training efficiency. The optimized Adam optimizer gives the best results, with higher detection accuracy than the SGD optimizer. The results show that the Adam optimizer has the highest accuracy reaching 85%.

Abstract

This community service program aimed to support environmental sustainability education by implementing a Smart Trash Bin system based on Internet of Things (IoT) technology at Sekolah Alam Indonesia, Cibinong. The initiative followed a structured Participatory Action Research (PAR) approach consisting of five stages: engagement, co-development, implementation, evaluation, and feedback. A technical team developed the system from Politeknik Negeri Jakarta. It integrated ultrasonic and load-cell sensors with ESP32 microcontrollers and wireless data transmission to enable real-time monitoring of waste volume and weight. In parallel, the Environmental and Forestry Agency (DLHK) of Depok City delivered a seminar on waste ecosystem management to improve knowledge among teachers and staff. Evaluation through pre- and post-test questionnaires showed that participants' knowledge scores enhanced from 13.78 to 15.61 (out of 17), while their environmental attitudes remained consistently high. This project demonstrates a scalable model for integrating technology and environmental education in schools

Abstract

A data center is a center for managing, storing and processing important data which includes sensitive information, business applications and technology infrastructure. Due to the importance of data centers in supporting organizational operations, their vulnerability to information security threats such as cyber attacks, unauthorized access has a serious impact on daily operations. The implementation of IDS is currently not optimal because in-depth analysis is difficult and requires experts to observe it. For this reason, an effective security monitoring system is needed on an Intrusion Detection System (IDS) based on Security Information and Event Management (SIEM) using the Wazuh platform. IDS plays an important role in detecting network security threats, while SIEM provides the ability to integrate and analyze security data from various sources. This research designs and implements Wazuh integration with SIEM to strengthen detection and response capabilities against security threats. Experimental methodology is used to evaluate the performance of the developed system, with a focus on intrusion detection, log analysis and security event management. The research results show that the integration of Wazuh with SIEM provides significant improvements in monitoring capabilities and response to security threats, which will be a valuable contribution in ensuring the security of networks and sensitive data.

Abstract

Indonesia is known as a country with very high biodiversity, one of which is reflected in the many bird species spread across various regions. The high public interest in birds presents challenges, in the form of increased bird trade practices, especially protected species. The main obstacle often faced by the public is the lack of information regarding the identification of protected bird species. Therefore, an application that can identify protected birds is needed. This study developed a web-based application using the Transfer learning approach in the classification of bird species in Indonesia. Five machine learning models were compared in this study: CNN, MobileNetV3Small, MobileNetV3Large, VGG16, and InceptionV4. The birds-525-species-image-classification dataset was used in the training process, then filtered to 54 bird species found in Indonesia. Model performance was evaluated using accuracy, precision, recall, and F1-score metrics. The developed web application uses React as the frontend and FastAPI as the backend and provides image upload and camera capture features to detect bird species directly. Test results show that MobileNetV3Large provides the most optimal performance and was selected for implementation in the system. In system testing through Black Box Testing, User Acceptance Test (UAT), System Usability Scale (SUS), and Net Promoter Score (NPS), it was shown that the application built had a good level of acceptance and ease of use
