Abstract

Video streaming is a technology play video files directly without having to download it. LTE (Long Term Evolution) is a mobile telecommunications technology as the evolution of HSDPA technology. LTE has the ability to transmit data at high speed. LTE network technology used in duplex mode FDD (Frequency Division Duplex) and TDD (Time Division Duplex). This study aims to determine the performance of video streaming on LTE network by using a TDD. The performance is analyzed include delay, packet loss, and throughput. The simulation results prove that the distance between UE and eNodeB with utilization factors influence the end-to-end delay, packet loss, and throughput in streaming video transmission. On the same data packet length, the greater the distance between the eNodeB with the EU, the greater the value of end-to-end delay. While the throughput of the smallest is 352 200 kbps which occurs when the distance between the eNodeB and UE is 10000 m with a utilization factor of 0.9.  Key-word : Video Streaming, LTE, TDD, jarak eNodeB ke UE, faktor utilisasi, delay end to end, packet loss, throughput

Abstract

Pembiasaan Pola Hidup Bersih dan Sehat Guna Memutus Mata Rantai Penularan Covid-19 adalah sebuah kegiatan pengabdian kepada masyarakat yang dilaksanakan oleh Program Studi Broadband Multimedia Jurusan Teknik Elektro PNJ. Kegiatan ini dilandasi oleh kenyataan bahwa saat ini sedang mewabah virus Covid 19 yang sangat cepat penyebarannya. Salah satu penyebab cepatnya penyebaran adalah kebiasaan buruk di masyarakat kita yang belum terbiasa membiasakan Pola Hidup Bersih dan Sehat sebagaimana yang disyaratkan oleh Kementerian Kesehatan RI. Seperti diketahui, virus covid 19 dapat masuk dan menjangkiti manusia adalah melalui mulut, hidung dan mata. Anggota tubuh manusia yang sering menyentuh bagian tersebut adalah tangan. Covid 19 menyebar menjangkiti manusia melalui droplet yang dikeluarkan penderita ketika ia berbicara, bersin atau batuk. Droplet tersebut bisa saja menempel pada benda-benda yang sering disentuh oleh tangan. Tanpa mencuci, apabila tangan yang tidak sengaja menyentuh droplet tersebut digunakan untuk makan atau menyentuh bagian mulut, hidung dan mata, maka kemungkinan besar ia akan tertular. Oleh karena itu sangat perlu untuk dilakukan program pembiasaan pola hidup bersih dan sehat diantaranya adalah mencuci tangan dengan sabun. Untuk mendukung program tersebut maka pada kegiatan pengabdian kepada masyarakat kali ini telah dilakukan pelatihan pembuatan sabun cuci tangan, pemberian tempat cuci tangan portable beserta sabun cuci tangan serta pembagian masker.

Abstract

Private 5G represents a promising wireless network technology that offers a wide range of opportunities for mobile operators. It enables them to meet the increasing data demands of their customers and provide enhanced capacities and user experiences. However, before deploying Private 5G, it's crucial to prepare the foundation properly, especially when choosing the right antena and Radio Frequency (RF) band. This research project focuses on evaluating the implementation of 4x4 MIMO and 8x8 MIMO antenas in the Greater Jakarta industrial area, covering a 35 km2 area, operating at a frequency of 2300 MHz with a 40 MHz bandwidth. The study involved data rate measurements and determined the number of required sites based on different modulation schemes. The findings revealed that using an 8x8 MIMO antena resulted in a data rate twice as high as that achieved with a 4x4 MIMO antena and required only a quarter of the sites. Additionally, simulation results demonstrated that the 8x8 MIMO antena provided better SS-RSRP and SS-SINR values compared to the 4x4 MIMO antena, with values of -91.51 dBm and 8.52 dB

Abstract

Excessive exposure to free radicals can cause skin to look dry and thin. Avocado seeds are a part of the fruit that is very rarely used and is even considered waste by society. Avocado seeds are known to contain good antioxidant activity to ward off free radicals. Topical preparations that are widely used to protect the skin from exposure to free radicals, one of which is lotion preparations with natural ingredients that contain antioxidants. This research aims to determine the antioxidant activity of avocado seed extract with different concentrations, formulate avocado seed extract lotion, distribute avocado seed extract lotion preparations, and determine the antioxidant activity of avocado seed extract lotion. The method used in this research is the in vitro 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. Each avocado seed was extracted with ethanol 50 %; 70 %; and 96 %. The best antioxidant results are made into cream preparations in 3 formulas, namely F1 0.01 %; F2 0.05 %; and F3 0.1 %. The best antioxidant test results were obtained from avocado seed extract with ethanol 70 % and an IC50 of 20.68 ppm with very strong antioxidant intensity. The three lotion formulations met the evaluation requirements for topical preparations and provided an antioxidant value of F1 of 128 ppm, F2 of 72 ppm, and F3 of 55 ppm. The conclusion of this research is that the highest antioxidants in avocado seed extract are found in the 70 % ethanol extract and in the formula 3 lotion preparation.
