Abstract

Automatic dependent surveillance-broadcast (ADS-B) is an equipment of a radar system to reach difficult areas. For radar applications, an ADS-B requires a low noise amplifier (LNA) with high gain, stability, and a low noise figure. In this research, to produce an LNA with good performance, an LNA was designed using a BJT transistor 2SC5006 with DC bias, VCE = 3 V, and current Ic = 10 mA, also a DC supply with VCC = 12 V, to achieve a high gain with a low noise figure. The initial LNA impedance circuit was simulated using 2 elements and then converted into 3 elements to obtain parameters according to the target specification through the tuning process, impedance matching circuit was used to reduce return loss and voltage standing wave ratio (VSWR) values. The LNA sequence obtains the working frequency of 1090 MHz, return loss of -52.103 dB, a gain of 10.382, VSWR of 1.005, a noise figure of 0.552, stability factor of 0.997, and bandwidth of 83 MHz. From the simulation results, the LNA has been successfully designed according to the ADS-B receiver specifications.

Abstract

The need for information exchange that encourages the development of telecommunications technology that can be a medium for delivering information to connect various places on the earth's surface or called terrestrial telecommunications. In wireless communication, the use of radio waves as a medium for propagation of information is considered more effective than physical media such as cables. A high radio frequency value such as X-Band will result in a smaller dimensional device. The use of microstrip type antennas has advantages in terms of small dimensions, inexpensive fabrication, and simple design but has low gain. Therefore, the design of a microstrip antenna with the array method becomes a solution that can be used in applications in terrestrial telecommunications. In this research, a microstrip antenna with a biquad-shaped patch has been designed and realized with a 4×1 array method that operates in the X-Band frequency band. This antenna works at a frequency of 11.96 GHz with a return loss of -23.51 dB and a VSWR of 1.13.

Abstract

Problems that often occur with electricity distribution network quality, continuity and availability services consumers. Study aims evaluate reliability of the 20 kV medium-voltage electricity distribution system at the Suci ULP Garut Kota feeder, where 2021 Suci feeder experienced 14 disturbances duration 791 minutes (13.1 hours), including a medium-voltage overhead line that broke 2 Phase. Determining the reliability index value electricity distribution system of the Kudus ULP Garut City feeder, mathematical calculations were carried out using RIA-section technique predetermined formula and simulated using ETAP software with study case reliability assessment. Based on the results of the study, improvement was made that the reliability value feeder was stable. Repairs were carried out 2 times, first repair, 2 fuse cutouts were installed and 4 transformers were moved, while the second repair was to divide the Suci feeder into 2 parts, namely the western Suci feeder and the eastern Suci feeder. So making these improvements the reliability index Suci feeder becomes stable and meets what has been SPLN 68-2: 1986, which is below SAIFI 3.3 times/customer/year and SAIDI 21.9 hours/customer/year.

Abstract

Chelonioidea or Sea turtle is an animal that is currently on the verge of extinction. Smart THEM prototype is designed to be able to maintain temperature of the sand medium in male mode (27–29oC) and female (29–32oC) using DS18B20 temperature sensor, and maintain the humidity of the sand medium (37.5%–50.2 %) using a capacitive soil moisture sensor with an indicator of the remaining water in the tank using an ultrasonic sensor. Turtle eggs incubated at high temperatures will give birth to female turtles, and at low temperatures, male turtles. This tool also utilizes internet networks for remote monitoring through the Blynk application by using a Mega+Wi-Fi microcontroller. In the test, Smart THEM is able to maintain the temperature in the male mode, which is 27.87–28.19 0C, and in the female mode, which is 30.19–30.31oC. Smart THEM is also able to maintain humidity between 45%-48%. The response time needed to increase temperature by 0.5oC is 20 minutes, and the humidity by 20% is 3 seconds. Blynk application is able to acquire temperature and humidity, and remaining water data in the tank from Smart THEM via internet.
