PENGEMBANGAN TRAINER WALLNET SEBAGAI MEDIA BELAJAR DALAM MEMPERSIAPKAN UJI KOMPETENSI KEAHLIAN JURUSAN TKJ DI SMK NEGERI 1 SAWIT
Get PDFABSTRAK Uji kompetensi keahlian merupakan ujian berbasis praktik yang digunakan sebagai tolak ukur kelulusan di jenjang SMK jurusan TKJ. Untuk mempersiapkan ujian tersebut, sering digunakan media pembelajaran berupa aplikasi simulator jaringan komputer. Namun penggunaan simulator pada pembelajaran uji kompetensi keahlian tidak benar-benar memberikan pengalaman kerja secara nyata karena tidak adanya interaksi langsung dengan perangkatnya jaringan secara riil. Berdasarkan permasalahan tersebut, maka dikembangkan sebuah media pembelajaran berbasis trainer yang bernama trainer WallNet. Desain trainer WallNet dibuat dalam bentuk rangkaian perangkat jaringan yang membentuk topologi jaringan beserta dengan gambar logo perangkat jaringan yang biasa digunakan pada simulator. Trainer WallNet dirancang agar siswa dapat mempelajari berbagai jenis topologi jaringan seperti topologi LAN, MAN, dan WAN. Tujuannya memberikan pengalaman interaksi lebih nyata secara langsung dengan perangkat jaringan sebernarnya. Penelitian ini dikembangan untuk mengetahui uji kelayakan dari trainer WallNet dalam mempersiapkan uji kompetensi keahlian jurusan TKJ. Berdasarkan hasil dari pengujian dapat disimpulkan bahwa (1) trainer WallNet berhasil dikembangkan sebagai sebuah media pembelajaran yang memberikan pengalaman belajar secara praktik dengan spesifikasi yang dapat memenuhi kebutuhan dalam mempersiapkan uji kompetensi keahlian jurusan TKJ di SMK Negeri 1 Sawit, (2) trainer WallNet masuk kategori Sangat Layak dengan presentase aspek kelayakan materi sebesar 86.7%, presentase aspek kelayakan media sebesar 82.7% dan presentasi aspek kepuasan pengguna sebesar 84.4%. Keywords: media pembelajaran, trainer, uji kompetensi keahlian, jaringan komputer. ABSTRAC The expertise competency test is a practice-based test that is used as a benchmark for graduation at the TKJ Vocational School level. To prepare for the exam, learning media are often used in the form of computer network simulator applications. However, the use of simulators in learning competency test expertise does not really provide real work experience because there is no direct interaction with the network device in real terms. Based on these problems, a trainer-based learning media was developed called the WallNet trainer. The design of the WallNet trainer is made in the form of a series of network devices that form a network topology along with the logo image of a network device commonly used in simulators. WallNet trainers are designed so that students can learn various types of network topologies such as LAN, MAN, and WAN topologies. The goal is to provide a more tangible interaction experience directly with the actual network device. This research was developed to find out the feasibility test of WallNet trainers in preparing competency tests in the TKJ majors. Based on the results of the test it can be concluded that (1) WallNet trainers have been successfully developed as a learning media that provides practical learning experience with specifications that can meet the needs in preparing competency tests of TKJ majors in SMK Negeri 1 Palm Oil, (2) WallNet trainers are in the category of Very Eligible with a percentage of aspects of material eligibility of 86.7%, percentage of aspects of media eligibility of 82.7% and presentation of aspects of user satisfaction of 84.4%.

ANALISIS DAN IMPLEMENTASI VIRTUALISASI DATA CENTER DI ICT CENTER FKIP UNS
No full textFaculty of Teaching and Education Science ( FKIP ) UNS , as one unit at the Universitas Sebelas Maret, have some information systems for electric data proccesing. This information system was entrusted to their ICT Center whose have responsible under the FKIP bureaucracy. The needs for information systems applications is increasing, but the growth of the information system is not proportional to the availability of existing server hardware. We need a solution to overcome the limitations of hardware resources in FKIP UNS. In this research, we use hypervisor virtualization to overcome limitations of server hardware, hypervisor virtualization choosen because it has a lower overhead and better performance than other types of virtualization. While the hypervisor software is using Proxmox VE. In this research, we tested the performance of the web server, then we compare its with other environment (eg: physical web server and virtualized web server). In order to deliver the same configuration and fair result, before the performance comparison we replicate the web servers from physical servers to virtual servers. The results of performance measurements on this web server interpreted that web server that runs in a virtualized environment is still able to serve users as well as web server running on the physical environment. Some statistics show a decrease in performance, but the performance degradation is still acceptable because the average performance degradation is only 7.8 % than web server running on physical environment. In addition, the ICT Center FKIP UNS financing will save server and network devices by as much as 48.11% and 35.134% when using virtualization in the data center infrastructure
ANALYSIS OF WIRELESS NETWORK SIMULATION BASED ON OPENWRT AND PFSENSE WITH QUALITY OF SERVICE INDICATORS ON LOW-COST NETWORK INFRASTRUCTURE
Get PDFThe need for high network traffic in Indonesia with the challenge of geographical topology that is difficult to reach makes the majority of internet network users access via wireless networks with limited budgets, resulting in poor internet QoS in Indonesia. An available solution to optimize low-cost network quality is to use the OpenWRT, open source router operating system with a focus on ease of application implementation in network projects. Another solution is pfSense, which is an open source router operation with a firewall network security focus to prevent intrusion. These two operating systems have different comparison methods in performance testing, making it difficult to make decisions about the performance differences between the two operating systems. This study aims to analyze the difference in performance and significance of open source operating systems with different development focuses on low-cost wireless network services. Analysis obtained from the quality of service measurement method on OpenWRT and Pfsense router operating systems on users that connected to a simulated wireless network topology. Data was collected by sending data between a number of users to the server and vice versa using iperf3 and mtr tools. The data consisted of QoS parameters: troughput, delay, jitter, and packet loss. The data shows that there are significant differences in several QoS parameters in the service of a number of users between the OpenWRT and PfSense operating systems. The results of this study show the limitations of each operating system in its implementation in low-cost wireless networks

Comparative analysis of PoS and PoA consensus in Ethereum environment for blockchain based academic transcript systems
Get PDFMany educational institutions worldwide now use blockchain to verify electronic document, often relying on Ethereum 1.0, which uses proof of work (PoW) or proof of authority (PoA). However, Ethereum 2.0, launched in 2022 by Ethereum Foundation operates on proof of stake (PoS). This study provides comparative analysis of PoS and PoA consensus in Ethereum environment specifically focusing on performance and scalability in the context of academic transcript databases. To demonstrate this, a student academic reputation information system was developed using two different blockchain technologies: Ethereum 1.0 with PoA and Ethereum 2.0 with PoS. This setup was used to obtain comparative analysis data for the two blockchain systems by measuring the throughput and latency. We observed how these platforms responded to an increasing number and frequency of transactions with Hyperledger Caliper. Results indicates that in performance testing, both consensus mechanisms exhibited. Scalability tests revealed that both consensus mechanisms experienced increased latency with higher loads. However, PoA system was superior in average throughput and latency than PoS system except in high transaction of data addition. The experiment result show that PoA system better than PoS system in context of academic transcript databases, making it more suitable to be implemented on that context
