Analysis of Antenna Types on the Effect of GSM Module Signals as Remote Vehicle Safety
The National Police revealed that in 2018 there were 165,918 cases of crime in Indonesia, with 19,380 cases of theft due to the lack of additional safety in vehicles. Thus, remote vehicle safety is needed to turn off the vehicle in the event of an act of theft. However, this remote security is still difficult to work if the signal quality from the BTS is weak. Because it needs a signal amplifier in the GSM module. The purpose of this paper is to analyze the effect of the GSM module signal on the injector response time as an android-based long-distance vehicle safety. The signal booster is useful so that this long-distance vehicle safety can work properly when the signal quality from the BTS is weak. The research method used is the two-way Anova method. There are two independent variables, namely: (1) BTS signal quality; (2) the antenna material is copper and aluminum. The dependent variable uses the injector response time. The test results show that in testing the BTS signal quality, copper antennas have the fastest response time compared to aluminum antennas. -60 dBm is 4.402 second and -113 dBm is 5.472 second. The conclusion of this study is that copper antennas respond faster than aluminum antennas, because copper has a higher conductivity than aluminum.
