Low Back Pain (LBP) is a leading cause of disability worldwide, which places a significant economic burden on the healthcare system. Nonspecific low back pain Low back pain (LBP) is defined as low back pain that is not caused by a recognized and recognized specific pathology. Low back pain does not cause death, but causes individuals who experience it to become unproductive so that it will cause a very large economic burden for individuals, families, communities, and governments. Promising physiotherapy measures for the treatment of LBP myalgia are extracorporeal shock wave therapy and laser. The purpose of this study was to determine the effect of radial shock wave therapy and laser therapy on pain in low back pain myalgia patients at EMC Hospital Cikarang in 2022. This research method was experimental with a quasi-experimental approach, namely research by conducting experiments to determine the symptoms or effects that arise. as a result of a certain treatment or experiment with a one group pretest posttest design, with the aim of knowing the effect of radial shockwave therapy and laser therapy on pain in low back pain myalgia patients at EMC Hospital Cikarang in 2022. The number of samples from this study was 12 people. who is an employee of EMC Cikarang Hospital in 2022 with complaints of LBP myalgia. Respondents will be measured the value of pain using Verval Analogue Scale (VAS) before and after being given radial shockwave therapy and laser therapy. The test used to analyze the data is the Wilcoxon test. The results of data analysis using the Wilcoxon test obtained a significance value (p-value) of 0.001 which is smaller than 0.05 (p<0.05), which means that there is a difference in the value of pain before and after giving radial shock wave therapy and laser therapy to pain in patients. low back pain myalgia. The conclusion is that there is an effect of giving radial shock wave therapy and laser therapy to reducing pain in low back pain myalgia patients at EMC Hospital Cikarang in 2022
It is necessary to have an LAPAN-TUBSAT (Lembaga Penerbangan dan Antariksa Nasional/ National Institute of Aeronautics and Space) (Technische University of Berlin Satellite) satellite data receiving system that is low cost and can be placed in various parts of Indonesia. This system will later spear head the data receiver and this meets all areas detected by the earth surveillance method in real time and can be recorded at the Earth Station. By using a helical antenna that is engineered independently with the rules of the S band at 2.22 GHz, it will be able to control the Indonesian region. The construction of this receiving antenna uses a helical antenna, a receiver antenna system that combines helix asa feed horn on a parabolic antenna is designed to be able to work at a center frequency of 2,220 MHz, a bandwidth of 27 MHz, LHCP polarization, and a minimum gain of 10 dB. With a Parabolic shaped reflection antenna with Prime Focus. With motor antenna is a full motion antenna with a perstep movement of 0.25 degrees on Azimuth and elevation. The Design will be acquisition the data from satellite, and with the helical antenna. The Helical that by requirement of the 2,22 GHz design. With the LHCP (Left Hand Circular Polarization) and with the a bandwidth of 27 MHz. for the antenna parabola as a catcher of signal from satellite we use type of Primefocus wichis the point focal in the central face of parabola and we will put feed Horn that include inside is the Helical feed antenna. Antenna have a spesification Movement is 0,25 degrees per second With the successful engineering of the development of Helical antenna, it can also later apply it to various other satellites with adjustments to the dimensions of the antenna only and the receiving system.
