This potentially causes interference between the two systems. This study aims to analyze the interference that occurs between satellite earth stations and 5G access points (AP), and between 5G AP and satellite sky stations. The analysis is carried out based on simulations using the Spectrum Engineering Advanced Monte Carlo Analysis Tool (SEAMCAT) software, with two scenarios. The first scenario is to analyze interference between the 5G AP and the FSS sky station. With the C/I interference criterion of 40.2 dB, the simulation results show that the 5G AP will not interfere with the FSS sky station. The second scenario is the interference simulation between FSS earth station and 5G AP. The simulation is carried out by varying the distance between the earth station and the 5G AP, the height of the earth station, and ...

Sistem penitipan barang konvensional pada umumnya membutuhkan proses yang memakan waktu seperti mencari loker yang kosong, memasukkan kunci, dan membuka kunci loker. Radio Frequency Identification (RFID) bekerja dengan mendekatkan antara tag dan reader sehingga sistem dapat bekerja secara otomatis, menjadikannya sebagai suatu solusi pilihan. Pada penelitian ini dikembangkan suatu sistem kunci loker otomatis yang dibuat dengan output berupa solenoid lock door yang berfungsi untuk membuka dan menutup loker otomatis dengan Raspberry Pi tipe B (RAM 512) dan pengiriman data berbasis RFID. Melalui pengujian dengan beberapa kondisi diperoleh catatan waktu di bawah 1 detik yang berarti sistem ini memberikan efisiensi dari segi waktu untuk membuka dan menutup kunci loker secara otomatis.

Indonesia berencana untuk menerapkan sistem televisi digital menggantikan sistem televisi analog dan untuk itu perlu disusun rencana pengkanalan frekuensi untuk setiap wilayah layanan guna menghindari masalah interferensi frekuensi antar pemancar televisi. Jumlah total kanal frekuensi yang digunakan untuk penyusunan rencana pengkanalan ini adalah 18 kanal yang dibagi dalam 3 group frekuensi untuk sistem re-use frekuensi. Perhitungan luas wilayah cakupan untuk suatu pemancar televisi digital menggunakan metode prediksi kuat medan berdasarkan Rekomendasi ITU-R P.1546-2 dan parameter teknis yang digunakan dalam perhitungan ini adalah parameter teknis DVB-T berdasarkan rekomendasi ITU-R BT.1368-3. Perhitungan kuat medan untuk setiap wilayah layanan televisi digital dilakukan untuk wilayah Sumatera, Jawa, Bali dan Nusa Tenggara. Sistem televisi digital dapat menghemat penggunaan frekuensi dari 41 kanal yang diperlukan untuk sistem televisi analog menjadi cukup 18 kanal saja. Hal ini berdampak frekuensi yang tidak digunakan lagi untuk keperluan televisi dapat digunakan untuk keperluan lainnya yang memerlukan frekuensi seperti telekomunikasi bergerak seluler ataupun untuk layanan data pita lebar lainnya. Kata kunci : televisi digital, kanal frekuensi, penyiaran

Beberapa faktor yang dapat mempengaruhi kinerja dari sel surya adalah temperatur dan shading effect. Perancangan dalam penelitian ini terdiri dari panel sel surya, solar charger, aki 12V, driver pompa, driver motor, sensor cahaya, sensor suhu, sensor tegangan, sensor level ketinggian air, limit switch, media komunikasi wifi, dan mikrokontroler. Pengaplikasian antena omnidirectional 17 dBi juga diharapkan dapat memperluas jarak jangkauan pemancar SMS dan WiFi serta mendapatkan keandalan jaringan yang lebih baik. Pemantauan panel sel surya dilakukan melalui website yang diakses melalui link AP dan IP address WiFi. Berdasarkan hasil pengujian pada alat diperoleh hasil sesuai perencanaan. Panel sel surya akan dibersihkan apabila suhu lingkungan melebihi 33 0 C dan tegangan charging aki kurang dari 12 V. Brgitu pula kuat sinyal dan reliabilitas jaringan yang diperoleh menggunakan antena omnidirectional 17 dBi pada pemancar menunjukkan hasil yang diharapkan sesuai rencana.

During the process of VM, some problems might occur. The issues, such as a heavy load of memory, a large load of CPU, a massive load of a disk, a high load of network and time-defined migration, might interrupt the business processes. This paper identifies the migration process among hosts for VM to overcome the problem within the defined time frame of migration. The introduction of VMs migration in a timely manner is to detect a problem earlier. There are workload parameters, such as network, CPU, disk and memory as our parameters. To overcome the issue, we have to follow the Model named Fuzzy rule. The rule follows the basic of tree model for decision-making. The application of the fuzzy Model for the study is to determine VMs allocation from busy VMs to vacant VMs for balancing purposes. The result of the study showed that the use of the fuzzy Model to forecast VMs m...

However, apart from quality, there are many other factors believed to influence users’ experiences of video streaming services in the era of 5G. The question then arises: what will determine the UX of streaming video services in the 5G era? This study aimed to discover what factors would influence 5G UX by using a conceptual framework involving measures of users’ predictive judgements of 5G combined with users’ measurements of current 4G UX, considering that there is no specific standard for measuring UX. Our case study is Indonesia, the world’s fourth-largest market, so the predictions may later become a reference for the priorities of implementing 5G technology. Our conceptual framework utilised the structural equation model (SEM) approach, based on the primary data of a 254-respondent sample of the Indonesian market. The questionnaire assesse...

Although many online learning facilities is available, the access requires adequate internet connection and supporting devices. This limited internet connection is a problem often faced by the students. The Internet connection can be made using a data package from a smartphone; however, lack of knowledge in using the features in a smartphone causes difficulties to share access and the solution taken is each smartphone is subscribed to an individual data packet. The lack of knowledge on sharing internet access using smartphones is the issue faced by teachers and parents at TPA Ziyaadatul Hasanah, Duren Sawit, East Jakarta. There is an alternative solution to overcome the problem by using Tethering and Hotspot technology to share the internet access using a single data package. Its application requires correct procedures so that the internet connection can be shared properly. Thi...
