Abstract

The development of fifth-generation cellular technology, commonly referred to as "5G" networks, is believed to be able to maximize data speed access needs. In order to maximize the utilization of the existing 5G network in Indonesia, Telkomsel providers are using a frequency of 2.3 GHz with a bandwidth of 50 MHz. So we need an antenna amplifier that is easy to fabricate and place anywhere to maximize the signal capture range. A microstrip antenna is a suitable antenna for this amplifier. The advantage of this antenna is that it has a light mass and is easy to fabricate. while the drawbacks come in the form of narrow bandwidth and small gains. Therefore, an antenna design with an artificial substrate and array technique was made to overcome this. The design of this microstrip antenna was made in the CST Studio Suite 2019. The design was carried out by entering the antenna dimension values to be simulated and seeing the parameters; if they are not suitable, then they need to be optimized again, and when they are appropriate, the design results are fabricated and printed. In testing the signal capture power using the Xirrus WiFi Inspector, this antenna was able to capture the signal beam, which was 105 meters or 40 meters further than not using the antenna. In addition, from testing, it is known that this antenna has a gain of 16.15 dBi. While in the simulation, it is also known that this antenna has the following characteristics: return loss: -32,353 dB (S11), -32,737 dB (S22), -33,974 dB (S33), -34,423 dB (S44), VSWR: 1,049 (VSWR 1), 1,047 (VSWR 2), 1.040 (VSWR 3), 1.038 (VSWR 4), impedance: 50.7 -111 MHz.

Abstract

This research focuses on efforts to increase customer satisfaction at tutoring institutions, especially at LBB Ganesha Operation Pacitan City. The focus is to analyze the impact of service quality, price, also location on student satisfaction. The research method used was a quantitative approach, with 80 LBB Ganesha Operation students in Pacitan City as the sample selected using a purposive sampling method. Analysis was done using multiple linear regression techniques with SPSS 22 for Windows. The test results show service quality influences 0.315, price -0.111, also location 0.444. The F test value shows these three variables jointly influence student satisfaction (F count 67.532 > F table 2.72, with a significance level of 0.000 < 0.05). The t-test shows service quality also location have a significant partial influence on customer satisfaction (t count 3.551 also 4.819 respectively > t table 1.990). In contrast, price does not have a significant partial influence (t count -1.812 < t table 1.990). The coefficient of determination shows 71.6% of the variation in customer satisfaction can be explained by service quality, price, also location, while the remaining 28.4% is influenced by other factors. It was concluded service quality also location had a positive also significant influence on student satisfaction at LBB Ganesha Operation Pacitan City, but the price did not have a significant influence.
