Abstract

Komunikasi adalah sesuatu yang sangat penting saat ini. Komunikasi berupa voice saat ini tidak hanya berupa melalui jaringan tradisional telepon biasa yaitu melalui POTS atau jaringan circuit switch tetapi sudah dapat melalui jaringan paket yang dikenal dengan VoIP (Voice Over Internet Protocol). Komunikasi VoIP dengan SIP (Session Initiation Protocol) paling sering berupa client dan server dimana client jika ingin melakukan koneksi VoIP maka harus mendaftar melalui server VoIP dan baru kemudian melakukan hubungan ke user VoIP lain yang terdaftar di server tersebut. Mengingat dari pengertian SIP sendiri adalah komunikasi peer-to-peer yang dimungkinkan untuk tidak menggunakan server. Maka model komunikasi secara peer to peer dilakukan dimana sekumpulan user VoIP SIP yang ingin melakukan komunikasi mengadakan komunikasi satu sama lain tanpa menggunakan server VoIP. Komunikasi VoIP antara user SIP satu dengan user yang lain dapat menggunakan P2PSIP (Peer-to-Peer Session Initiation Protocol). Dalam komunikasi peer-to-peer sangat erat dengan algoritma DHT (Distribution Hash Table) untuk pengaturan penyambungan dan pemisahan maupun routing client dalam sebuah jaringan peer-topeer.Hasil yang diperoleh yang paling baik dilihat dari parameter QoS (Quality of Service) layanan untuk delay, PDD, dan MOS adalah Peer-to-Peer SIP. Sedangkan untuk nilai throughput, jitter, dan packet loss adalah Client-Server SIP.Kata kunci : Peer to Peer, P2SIP, SIP, Distribution Hash Table

Abstract

In this study, weproposed compressive sampling for MRI reconstruction based on sparse representation using multi-wavelet transformation. Comparing the performance of wavelet decomposition level, which are level 1, level 2, level 3, and level 4. We used gaussian random process to generate measurement matrix. The algorithm used to reconstruct the image is l_1 norm. The experimental results showed that the use of wavelet multi-level can generate higher compression ratio but requires a longer processing time. MRI reconstruction results based on the parameters of the peak signal to noise ratio (PSNR) and structural similarity index measure (SSIM) show that the higher the level of decomposition in wavelets, the value of both decreases.

Abstract

Software defined network (SDN) is a new paradigm in network engineering, where control plane and data plane are separated. Data plane is carried out on each node, while a control plane is centrally located. In conventional networks, the planes are implemented in the firmware of the router. In this paper, we implemented multimedia services on SDN using exterior and interior routing protocols, such as open shortest path first (OSPF), border gateway protocol (BGP) and routing information protocol (RIP), measured the quality of service (QoS), and analyze the measurement results. The test results showed that the greater the background traffic provided, the smaller the throughput. Traffic on the network will be congested, so the available bandwidth is also increasingly used up so that the number of bits sent every second decrease. Mean opinion score (MOS) test results are 4 showing good categories based on ITU-T standards.

Abstract

ABSTRAKPada makalah ini, kami membandingkan protokol routing proaktif Optimized Link State Routing (OLSR) dan protokol routing reaktif Ad-hoc on-demand distance vector (AODV) dan Dynamic Source Routing (DSR) pada model propagasi Shadowing dan pergerakan pada mobile adhoc network (MANET). Terdapat dua skenario pengujian, yaitu dampak dari kecepatan pergerakan pengguna dan variasi waktu jeda pengguna dengan mobilitas Random Way Point (RWP). Hasil simulasi menunjukkan bahwa semakin besar kecepatan maka kinerja throughput akan menurun, sedangkan delay dan Normalized Routing Load (NRL) akan meningkat. Semakin lama waktu jeda, semakin lama topologi berubah, akibatnya parameter throughput meningkat sedangkan delay end-to-end dan NRL menurun. OLSR proaktif menunjukkan kinerja terbaik dibandingkan dengan protokol lain berdasarkan parameter throughput, sedangkan AODV reaktif mengungguli penundaan end-to-end dan parameter NRL.Kata kunci: Protokol perutean, shadowing, Mobility, MANET ABSTRACTIn this paper, we compared the proactive routing protocols Optimized Link State Routing (OLSR) and the reactive routing protocols Ad-hoc on-demand distance vector (AODV) and Dynamic Source Routing (DSR) in shadowing propagation and mobility model on mobile adhoc network (MANET). There are two test scenarios, such as the impact of user movement velocity and variations in user pause time with Random Way Point (RWP) mobility. In user velocity testing, the greater the speed, the throughput performance will decrease, while the delay and Normalized Routing Load (NRL) will increase. The pause time test describes the dynamics of changing network topology. The longer the pause time, the longer the topology changes, as a result, the throughput parameter increases while the end-to-end delay and NRL decrease. The proactive OLSR shows the best performance compared to other protocols based on throughput parameters, while the reactive AODV outperforms for end-to-end delay and NRL parameters.Keywords: routing protocol, shadowing, Mobility, MANET

Abstract

The industrial revolution 4.0 greatly impacts the learning curriculum, especially at the vocational and higher education levels. They are required to play an active role in the success and acceleration of the implementation of industry 4.0. Higher Education becomes a kind of place for preparation or training for human resources (HR) to provide skills that are directly related to the application and development of applications that support industry 4.0. In order to support the government's efforts, the community service team at Telkom University and the Telkom Jakarta Institute of Technology actively participated in collaborating with SMK Nagrak Purwakarta. This community service focuses on bridging productivity between departments in Nagrak Vocational School such as the Food Crops and Horticulture Agribusiness (ATPH) department and the network computer engineering department (TKJ) so as to produce the right cultivation, namely Internet of Things (IoT) based aquaponics. This activity consists of making modules and video tutorials for students and teachers, designing sensors and devices, and making monitoring applications on smartphones to monitor aquaponic plants. The sensor designed consists of a PH detection sensor in the air and an oxygen sensor installed in the school's aquaponics garden. The students and teachers were enthusiastic in participating in workshops regarding IoT materials. Not only getting material, students and teachers then do direct practice to make aquaponics and monitor temperature. Based on a survey of the results of this community service implementation, teachers and students are very satisfied and enthusiastic about and hope that community service activities can be carried out on an ongoing basis.

Abstract

Technological developments in the Internet of Things (IoT) are growing rapidly, especially in agriculture. The lack of understanding of the development of IoT is the basis for the service team to conduct training for students and teachers. The service is carried out by the socialization method to students regarding IoT for agriculture. In practice, community service utilizes hydroponics that has been built in the SMK Yasti Cisaat Sukabumi area. After evaluating the implementation of community service, it can be seen that students have succeeded in understanding IoT based on artificial lighting and successfully implementing IoT tools in the school's hydroponic home. At the end of the activity, feedback is given as an effort to evaluate this community service activity. There are 5 statements in the questionnaire with an average result of 94.8%. These results show that the community service partners are very satisfied with the IoT training and hydroponic implementation.
