Abstract

Pada artikel ini, penulis mengembangkan kerangka analisis kausal peristiwa kritis dalam penelitian studi kasus. Peristiwa penting didefinisikan sebagai peristiwa kontinjensi yang mempunyai dampak sebab akibat terhadap hasil suatu kasus tertentu. Penulisan ini menggunakan analisis teori himpunan untuk memberikan definisi dan alat pengukuran untuk menguji kontingensi dan signifikansi kausal dalam penelitian studi kasus. Seperangkat alat tersebut terdiri dari pedoman untuk menyimpulkan tingkat kontinjensi kejadian dengan menggunakan ekspektasi teoretis. Perangkat lainnya adalah pedoman untuk menggunakan kasus-kasus kontrafaktual guna menentukan sejauh mana peristiwa-peristiwa tertentu diperlukan dan cukup untuk menghasilkan hasil tertentu dalam kasus-kasus tertentu. Menyadari bahwa situasi akses jaringan menjadi sangat lambat. Praduga ada aktivitas yang tidak biasa terjadi di jaringan, dan aktivitas serangan mungkin telah terjadi. Untuk mengetahui penyebabnya, menganalisis hasil sniffing trafik menggunakan Wireshark. Dua kali penggalian data dilakukan pada waktu dan kesempatan yang berbeda. Menyelidiki kejadian tersebut dengan melakukan analisis pada data PCAP pada File Attack a.pcap atau Attack a.pcap. Hasil analisa dibahas dengan mengamati trafik yang dihasilkan pada jaringan dengan menangkap file PCAP.

Abstract

Image compression is a crucial research topic in today's information age, especially to meet the demand for balanced data compression efficiency with the quality of the resulting image reconstruction. Common methods used for image compression nowadays are based on autoencoders with deep learning foundations. However, these methods have limitations as they only consider residual values in processed images to achieve existing compression efficiency with less satisfying reconstruction results. To address this issue, we introduce the Attention Block mechanism to improve coding efficiency even further. Additionally, we introduce post-filtering methods to enhance the final reconstruction results of images. Experimental results using two datasets, CLIC for training and KODAK for testing, demonstrate that this method outperforms several previous research methods. With an efficiency coding improvement of -28.16%, an average PSNR improvement of 34%, and an MS-SSIM improvement of 8%, the model in this study significantly enhances the rate-distortion (RD) performance compared to previous approaches.

An automatic door model based on IoT using VLC has been successfully assembled for user security at home. This communication, with a wavelength of 650 nm in red light, was tested for 20 cm. The photodiode receiver activates the servo motor to open the door with a maximum rotation angle of 120 degrees. The open door process consists of 6 different conditions displayed on the LCD and transmitted via the internet to the website. In a comprehensive evaluation, the system operates optimally. In addition, VLC was also tested as a carrier signal to examine the voltage sent by the laser. Based on the experiment, the data sent can still be received well, even though there is a voltage change up to 1.5% at the photodiode receiver.Keywords: Visible Light Communications (VLC), Internet of Things, automatic door, security, carrier signal

Abstract

Untuk mebuat jaringan yang handal, dikembangkan lah berbagai teknik khusus, seperti teknik subnetting dan penggunaan hardware yang lebih baik (antara lain switch dan router) maka muncullah konsep VLAN (Virtual Local Area Network). Agar antar VLAN dapat berkomunikasi dibutuhkan suatu jembatan yang berada pada lapisan OSI layer 3 yaitu router. Dengan menggunakan konfigurasi router “Router on a stick”, yang mana sebuah interface physical me-routing traffic antara beberapa VLAN pada satu network. Router interface dikonfigurasikan untuk beroperasi sebagai link trunk dan terhubung dengan sebuah port switch dalam mode trunk. Router menunjukkan inter-VLAN routing dengan menerima traffic VLAN yang telah di tag pada interface trunk dari switch dan secara internal merutekan antar VLAN menggunakan sub-interface.. Implementasi VLAN Router on a Stick dapat meningkatkan performansi jaringan computer dalam perkembangan jaringan computer kedepannya.

Abstract

The EfficientDet method, which is implemented on the Raspberry Pi for real-time detection in resource-constrained contexts, is the basis for the smart home security system presented in this study.  The system integrates CCTV cameras, motion sensors, and detectors to identify and classify objects, sending notifications via WhatsApp via the Twilio API.  The EfficientDet-D0 model achieves an accuracy of 94.8%, an average processing time of 45 ms, and a memory usage of about 850 MB.  When compared to moving individuals or non-human things, testing shows that stationary human items have a higher detection accuracy.  Notifications are transmitted roughly every three seconds, with an average latency of 1.4 to 1.8 seconds.  The suggested method provides object recognition, real-time monitoring, and configuration flexibility in contrast to traditional IoT-based systems.  These results highlight the potential of EfficientDet as a reliable and adaptable solution for home security.  Future improvements include improving accuracy in a variety of environmental conditions and implementing adaptive learning.

Abstract

Brain tumor classification is an essential step in medical image analysis, contributing to timely diagnosis and effective treatment planning. This study introduces a brain tumor classification model that integrates EfficientNet with Dual Path Networks (DPN) and a Multi-Head Self-Attention (MHSA) mechanism. The model is applied to classify three major types of brain tumors—glioma, meningioma, and pituitary—using MRI images. The integration of DPN allows the model to leverage both residual and dense connections for enhanced feature representation, while the MHSA module refines global and local contextual information. Experimental evaluation demonstrates that the proposed model achieves an overall accuracy of 97.82%, sensitivity of 97.83%, specificity of 98.41%, precision of 98.34%, and F-score of 98.08%. These results indicate competitive performance compared to widely used architectures such as CNN, ResNet, and DenseNet, suggesting that the combined use of EfficientNet, DPN, and MHSA can provide a robust approach for brain tumor classification.

Abstract

Advances in computer network technology and increased use of Internet information have reduced IPv4 offerings. This requires a computer network protocol that can replace the role of IPv4 which is currently limited/loose. Also known as Internet Protocol Verses 6 (IPv6), it aims to improve on IPv4 and does not represent a fundamental change from IPv4. Features that are available in IPv4 are also available in IPv6, but features that do not work in IPv4 are available in IPv4. IPv6 is no longer used. A transition mechanism is required to forward IPv6 packets to an existing IPv4 network and vice versa. One of the available mechanisms is automatic tunneling (abbreviated as Tunneling). The EVE-NG simulator is used to implement and study the routing protocol (OSPFv3) on IPv6 networks. To check the results, use the traceroute, ping command. The Juniper platform is implemented in this small virtual network to test the OSPFv3 protocol on an IPv6 network. This research explains how to assign IPv6 addresses on Juniper routers and end devices as well as their configuration. The Internet protocol layer is responsible for receiving and sending data packets within the network. In the virtual environment simulation mode, Juniper packets are analyzed and packet forwarding via IPv6 on OSPFv3 is used to make decisions for protocols in the IPv6 environment that are faster, and more secure.
