Abstract

The data distribution mechanism of internet protocol (IP) technology is inefficient because it necessitates the user to await a response from the server. Named data networking (NDN) is a cutting-edge technology being assessed for enhancing IP networks, primarily because it incorporates a data packet caching technique on every router. However, the effectiveness of this approach is highly dependent on the router's content capacity, thus requiring the use data replacement mechanism when the router capacity is full. The least recently used (LRU) method is employed for cache replacement policy; yet, it is considered ineffective as it neglects the content's popularity. The LRU algorithm replaces the infrequently requested data, leading to inefficient caching of popular data when multiple users constantly request it. To address this problem, we propose a segmented LRU (SLRU) replacement strategy that considers content popularity. The SLRU will evaluate both popular content and content that has previously been popular in two segment categories, namely the probationary and protected segments. Icarus simulator was used to evaluate multiple comprehensive scenarios. Our experimental results show that the SLRU obtains a better cache hit ratio (CHR) and able to minimize latency and link load compared to existing cache replacement policies such as First In, First Out (FIFO), LRU, and Climb.

Abstract

Load balancing adalah mekanisme untuk membagi beban komputasi ke beberapa server. Load balancing ini bertujuan untuk mengoptimalkan resource dan meningkatkan throughput agar server tidak mengalami overload. Software Defined Network (SDN) adalah teknologi jaringan komputer yang memisahkan fungsi Data Plane dan control plane. Protokol OpenFlow digunakan untuk mengontrol/mengelola arus lalu lintas, tetapi OpenFlow ini telah ditentukan dan tidak dapat diubah atau dimodifikasi. Untuk mengatasi masalah di atas, Programming Protocolindependent Packet Processors (P4) adalah bahasa pemrograman untuk pemrograman top-down yang dapat menentukan bagaimana pipeline pada switch bekerja dan bagaimana paket-paket ini dapat diproses. P4 ini dapat mengatasi kelemahan OpenFlow yang kurang fleksibel dalam mengontrol/mengatur arus trafik dan memungkinkan berjalannya proses load-balancing. Pada Tugas Akhir ini telah dilakukan simulasi dan analisis load balancing pada infrastruktur jaringan yang dapat diprogram berbasis bahasa P4. Algoritma round-robin dengan P4 memiliki nilai throughput rata-rata 127,61 KB/s. Algoritma hash IP dengan P4 memiliki nilai throughput rata-rata 127,50 KB/s. Algoritma round robin memiliki nilai response time rata-rata 3,13 ms; pada algoritma hash IP, nilai rata-ratanya adalah 12,16 ms. Nilai response time sistem berbasis P4 dengan algoritma round robin lebih baik daripada algoritma hash IP, dan request loss kedua sistem dapat mendistribusikan request dengan baik sehingga request loss sebesar 0%.Kata Kunci—load balancing, data plane, P4, round robin, IP hash

Abstract

The coastal area of Medan Marelan District in Medan City, North Sumatra Province, has extensive mangrove forests that have not been fully utilized. LKP Walidayna supports the empowerment program for productive communities in the coastal areas of Medan City. Currently, LKP Walidayna has provided training on processing mangrove fruits to the community, turning them into various processed food products such as Mangrove Pudding, Mangrove Syrup, Mangrove Jam, and Mangrove Dodol. The vocational training institution (LKP) is one form of non-formal education that communities can utilize to enhance quality, skills, and productivity. However, LKP Walidayna faces limitations, including the lack of effective information media to market its products more widely. Therefore, the proposed solution is the creation of a website and e-commerce platform to promote LKP Walidayna's mangrove products using effective and attractive marketing techniques. The e-commerce platform would contain information about activities, especially the processing of mangrove products. Based on feedback from participants in the product design and marketing strategy training for processed mangrove products through the website, it is concluded that the conducted training activities align with the needs of LKP Walidayna. LKP Walidayna expressed satisfaction with the visually appealing and user-friendly website.

Abstract

Abstract. This community service program aims to accelerate the digitalization of education in Pesisir Barat Regency, Lampung Province, through the implementation of Content Delivery Network (CDN) technology using Starlink services and the Learning Management System (LMS) Moodle. The 3T areas (frontier, outermost, and underdeveloped) in this region face infrastructure challenges that hinder stable and fast internet access, which is crucial to support technology-based learning processes. This program involves the installation of network devices, such as Starlink for stable internet access, gigabit switches, and the integration of the Moodle-based e-learning system. Additionally, intensive training is provided to teachers, administrators, and students on using Moodle as a digital learning platform and managing technology-based educational content. The program's success is measured through several parameters, including internet stability and speed, the improvement of digital skills among teachers and students, and the adoption and utilization rates of LMS Moodle in the learning process. Speed test results show a significant improvement. Survey results indicate a substantial impact on teachers' digital literacy. Based on questionnaires distributed to a total of 30 training participants, 60% (18 participants) reported being very satisfied with the alignment of the training materials with their needs. Regarding the delivery of the materials, 63.33% (19 participants) were very satisfied, 26.67% (8 participants) were satisfied, 6.66% (2 participants) were neutral, and 3.33% (1 participant) were very dissatisfied. Direct observation during the implementation showed that teachers could effectively utilize Moodle LMS to manage digital classes. They were trained to create and organize teaching materials, assign tasks, and monitor student progress. This evaluation also highlights the potential for replicating and sustaining the program in other schools within similar regions. Through this evaluation approach, the program is expected to have a tangible impact on improving the quality of learning, expanding digital access, and serving as a model for implementation in other 3T areas across Indonesia.

Abstract

The rapid advancement of 5G technology has accelerated the development of vehicular networks, where reliable Vehicle-to-Vehicle (V2V) communication is essential for intelligent transportation systems. This study evaluates the performance of Cellular Vehicle-to-Everything (C-V2X)-based V2V communication using a trace-driven simulation approach in a semi-enclosed environment. A realistic mobility model is generated using Simulation of Urban Mobility (SUMO) based on OpenStreetMap data and integrated with the WiLabV2Xsim simulator implementing the 3GPP C-V2X Mode 4 standard. The evaluation is conducted using Packet Reception Ratio (PRR), Channel Busy Ratio (CBR), and packet delay under varying vehicular densities. The results show that increasing vehicle density leads to a significant degradation in PRR while increasing CBR and delay, indicating higher channel congestion and communication interference. Increasing bandwidth improves communication reliability, whereas higher transmission power provides limited benefits in dense scenarios. These findings highlight the importance of efficient resource allocation and congestion-aware mechanisms to ensure reliable V2V communication in 5G-enabled vehicular networks. However, this study is limited to simulation-based evaluation and does not consider real-world deployment constraints. The study contributes to understanding the scalability and performance behavior of C-V2X systems in realistic vehicular environments.
