Abstrak Cashless Payment merupakan suatu metode pembayaran non-tunai. Metode pembayaran tersebut sudah diterapkan pada aplikasi perdangan elektronik (e-commerce). Dalam aplikasi e-commerce dapat menerapkan cashless payment dengan integrasi payment gateway. Payment Gateway adalah suatu jalur pembayaran non tunai yang dimana melakukan transaksi secara online dalam aplikasi. Selain aplikasi e-commerce, payment gateway dapat diintegrasikan pada aplikasi pembayaran lainnya seperti pembayaran keterlambatan pengembalian buku di Open Library Telkom University . Proses pembayaran denda saat ini masih memilki kendala yaitu peminjam tidak bisa melakukan secara cash melainkan cashless. Dengan aplikasi yang sudah terintegrasi payment gateway, peminjam dapat melakukan bayar denda secara mandiri atau disebut dengan self payment. Self payment tersebut dilakukan tanpa kontak secara langsung dengan admin. Sebagai konfirmasi ketika sudah selesa i melakukan pembayaran dengan dikirimkan email kepada user melalui Simple Mail Transfer Protocol (SMTP), selain itu transaksi yang sudah dilakukan oleh user akan tersimpan dalam database sebagai riwayat pembayaran. Aplikasi pembayaran keterlambatan buku dilakukan pengujian nilai delay dari client menuju server pada payment gateway dan utillization resource dalam penggunaan CPU, Memory dan Network. Pengujian aplikasi terhadap delay menghasilkan 15.43 ms pada satu device dan 101.29 ms pada dua device, nilai pengujian sudah memenuhi ITU-T G.1010 dalam proses transaksi. Sedangkan utillization resource CPU sebesar 7%, Memory 10% dan Network I/O 151.5 Kbps Kata kunci : Cashless Payment, Payment Gateway, SMTP, Open Library, Delay, Utillization Resource Abstract Cashless Payment is a non-cash payment method. This payment method has been applied to electronic trading applications (e-commerce). In e-commerce applications, cashless payments can be implemented with payment gateway integration. Payment Gateway is a non-cash payment channel which make online transactions in the application. In addition to ecommerce applications, payment gateway can be integrated into other payment applications such as late payment for returning books at the Telkom University Open Library.The process of paying fines still have obstacles, when patron canâ€™t transaction via cash, but cashless. With an application that has an integrated payment gateway, patrons can pay fines independently , which is known as self payment. Self payment not made directly interacting with admin. As confirmation when the payment has been completed by sending an email to the user via the Simple Mail Transfer Protocol (SMTP), and transactions that have been made by the user will be stored in the database as payment history.The book delay payment application has been testing for delay from the client to the server on the payment gateway and resource utilization in CPU, Memory and Network usage. Application testing for delay produces is 15.43 ms on one device and 101.29 ms on two device the value of testing has met the ITU-T G.1010 standard of delay in process transactions. Meanwhile value of utilization resource for CPU is 7%, Memory 10% and Network I/O 151.5 Kbps. Keywords: Cashless Payment, Payment Gateway, SMTP, Open Library, Delay, Utillization Resourc

Abstrak Wireless Body Area Network (WBAN) merupakan jaringan nirkabel dengan penggunaan sensor untuk tubuh manusia. WBAN dapat diterapkan untuk pemantauan kesehatan. Berbeda dengan Wireless Sensor Network (WSN) yang memiliki penggunaan lebih luas. WBAN masih berkembang dan memiliki masalah pada efisiensi energi dengan tetap memperhitungkan performansinya. Sehingga, diperlukan algoritma routing yang dapat meminimalisir masalah tersebut. Cluster based routing sudah diuji pada WSN, yang populer adalah Low Energy Adaptive Clustering Hierarchy (LEACH), sementara pada WBAN, routing Anybody sudah pernah diimpelementasikan. Pemilihan Cluster Head (CH) pada Anybody dilakukan berdasarkan kepadatan tiap node, sementara pada LEACH, CH dipilih secara acak dan bergantian setiap round. Dengan perbedaan tersebut, maka Anybody dan LEACH adalah algoritma routing berbasis cluster yang akan digunakan pada penelitian ini. Dari hasil simulasi WBAN menggunakan Castalia OMNeT++, routing Anybody dan LEACH dapat diimplementasikan, dengan jumlah hop tidak lebih dari 2 hop. Routing overhead Anybody lebih kecil dibanding LEACH. Packet Delivery Ratio (PDR) Anybody lebih besar 14% dibandingkan LEACH. Sehingga throughput dan packet loss juga lebih baik. Namun, LEACH lebih efisien hampir 55% dalam konsumsi energi dan network lifetime 55% lebih lama. Jadi, untuk mementingkan kehandalan pengiriman dapat menggunakan routing Anybody. Apabila mementingkan masalah efisiensi energi, dapat menggunakan routing LEACH. Kata kunci : WBAN, Cluster based routing protocol, Anybody, LEACH Abstract Wireless Body Area Network (WBAN) is a wireless network with the use sensors for the human body. WBAN can be applied to healthcare monitoring. Unlike the Wireless Sensor Network (WSN) which has wider usage. WBAN is still developing and has problems with energy efficiency while still calculating performance. Routing algorithm is needed that can minimize the problem. Cluster-based routing has been tested on WSN, which popular is Low Energy Adaptive Clustering Hierarchy (LEACH), while in WBAN, Anybody routing has been implemented. Selection of Cluster-Head (CH) Anybody is based on density of node, while in LEACH, CH is chosen randomly and alternately each round. With these differences, Anybody and LEACH is cluster-based routing algorithm will use in this project. From the WBAN simulation results using Castalia OMNeT++, Anybody and LEACH routing can be implemented, with no more than 2 hops. Anybody routing overhead is smaller than LEACH. Packet Delivery Ratio (PDR) Anybody 14% greater than LEACH. So that throughput and packet loss are also better. However, LEACH is 55% more efficient in energy consumption and network lifetime is 55% longer. So, to prioritize reliability of delivery data can use routing Anybody. If concerned with energy efficiency issues, can use LEACH routing. Keywords: WBAN, Cluster based routing protocol, Anybody, LEACH

Virtualization technology is slowly being used to build network infrastructure called Network Function Virtualization (NFV). It takes network functions such as firewall, load balancer, IPS out of its hardware then uses its software to be run on high specification server. It helps to reduce vendor lock-in and creates a multiplatform network function environment for telecommunication or Internet Service Provider (ISP) company. It has a lot of benefits compared to a traditional network. One of them is reducing the number of hardware that is used in the telecom industry. This technology runs on the hypervisor that is used for the hardware management. One of the important components from NFV is Virtualized Network Function (VNF). In NFV, network devices are run on a server so that a firewall is needed. If an attack occurs on the network, it will interfere the existing network components. This paper focuses on analyzing the performance of two firewall systems: pfSense, and FortiGate. Both firewalls run on the VMware ESXi hypervisor. It compares the firewall performance in normal conditions without attacks and under SYN DoS attacks. Besides, firewall failover capabilities are evaluated. Based on the overall testing results, FortiGate has better performance than pfSense. It has better ability in handling DoS SYN attack because of lower throughput performance degradation and better FTP performance. It is concluded that FortiGate has best performance if it is compared to pfSense.

A smart grid aims to integrate alternative and renewable energy sources. NDN has the advantage of being better than IP networks and can optimize the delivery of information. The concept of Named Data Networking (NDN) is designed for smart grid systems. This study aims to implement the NDN concept on a smart grid system and analyze forwarding and caching strategies. The implementation of the system strategy is supported using the NDN network topology, which is based on IEEE 39. The author evaluates network performance by paying attention to parameters such as delay and cache hit ratio. From the data the author obtained, it can be concluded that the best route-LRU and client control-LRU systems are better choices to be implemented in a smart grid communication system than the best route-FIFO and client control-FIFO systems. In other words, the LRU caching override method is superior to the FIFO caching override method. Meanwhile, the forwarding method does not show significant graphical results. This happens because the forwarding method that the authors use has the same route determination. Something that differentiates between the best route and client control is only the control of selecting the path. The best route is controlled by the producer, and client control is controlled by the consumer.

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.

Named Data Network (NDN) is a next-generation network architecture that shifts the traditional data communications paradigm Unlike conventional networks that rely on IP addresses, NDN delivers content based on data names rather than specific locations. In NDN, consumers express their requests by sending interest packets containing content names. These names are then propagated through the network nodes, which forward them to the appropriate destinations. The forwarding strategy in an NDN network plays a crucial role in ensuring efficient data delivery. This strategy includes a set of rules that determine the next hop for each interest packet. These rules are designed to optimize the forwarding process, minimizing delays and improving network efficiency. However, if the forwarding strategy is implemented without accurately identifying the appropriate face (i.e., the network interface) to forward interests toward the producer or the nearest cache node, it can lead to significant delays and packet drops. This, in turn, negatively impacts Quality of Service (QoS) parameters and the overall performance of the NDN network. This study applies supervised learning to classify consumer-requested interests to overcome this issue. This technique leverages several related variables to accurately classify these interests. The outcomes of the conducted research demonstrated that raw data from the mini-NDN output can be processed and transformed into a usable dataset. This data is then utilized to train a classification model with supervised learning. In a scenario with 9 NDN nodes and varying numbers of interests, distributed both uniformly and according to Zipf's law, the Random Forest model performs effectively, achieving an accuracy rate of 86.2% with an error rate of 14.8%.
