M. Fauzan Edy Purnomo — 2023-03-20

Microstrip antennas are used in various dimensions and shapes of microstrip antennas according to needs. In this use it allows bending of the microstrip antenna which changes the characteristics or parameters. In this research a microstrip antenna is designed with 24 star and 12 star patches and a staircase-shaped ground plane working at a frequency of 2.4 GHz. Design and simulation were carried out on the CST Studio Suite 2018 software and measurements were carried out with the ARINTS VNA. The simulation results show that bending causes yield degradation in the microstrip antenna parameters which include Return Loss, VSWR, Gain, Directivity, and Efficiency. the measurement results show that there is degradation in the Return Loss, VSWR, and Gain parameters. the smaller the bending radius that is done so that the antenna bends more, the performance quality value of the antenna parameters decreases.

Rainfed rice fields are agricultural areas whose irrigation systems depend on the rainy season. In the dry season, agricultural areas are not planted. The villagers make a living in the agricultural area. During the rainy season, some people cultivate crops, and during the dry season, some people turn to entrepreneurs or work in cities. This went on for years, and to deal with it, farmers built wells and used fossil fuel engines to pump the water. According to the case found in Duri Village, Slahung-Ponorogo District, the right technology is needed, namely hybrid electric water pump technology. A solution to the problem of irrigating rainfed rice fields. Engineering a solar power plant using hybrid electricity is an alternative option that can be implemented. Based on the results of the evaluation of this solar panel design, it produces 200 Wp of energy with an optimum voltage of 21.1 volts and a maximum current of 9.0 A. The optimum average solar cell voltage is 20.42V when it is hot and the charging voltage is 14.3V DC current. On cloudy days, the average voltage is 19.20 volts, and the charging voltage is 13.60 volts. Sunlight capacity is 8 hours per day, with normal full exposure of about 5 hours/day. Based on the review of the findings, it is necessary to increase the power supply capacity to a greater extent.. fossil fuel engines, water pump technology

Perancangan Antena Metamaterial Patch Circular Untuk Teknologi 5G Dengan CSRR Pada Frekuensi 3.5 GHz

Kenita Tri Cahyani — 2023-03-20

The development of 5G technology at this time has a much faster speed, capacity and latency in accessing data compared to 4G technology. 5G technology has several components that are influential in the application of 5G technology, one of which is the antenna. Microstrip antennas are antennas that have simple materials, smaller antenna dimensions, so that production costs are cheaper, affordable and the performance of microstrip antennas is quite good. Microstrip antenna has several drawbacks, namely low gain and not wide bandwidth. In this study a circular patch microstrip antenna was designed using FR-4 material using a relative dielectric constant of 4.4, a loss tangent of 0.02 and a substrate thickness of 1.6 mm. The microstrip antenna that will be added to the groundplane section uses a metamaterial structure, namely the Complementary Split-Ring Resonator (CSRR) which operates at a frequency of 3.5 GHz. The addition of the CSRR metamaterial structure aims to increase antenna bandwidth and miniaturization. The simulation results of a microstrip antenna without CSRR can work at a frequency of 3.5 GHz with a return loss of -15.71 dB, a VSWR of 1.39, a gain of 2.121 dBi, a bandwidth of 120 MHz and the resulting radiation pattern is unidirectional. While the antenna that has been added CSRR at a frequency of 3.5 GHz has a return loss of -19.50 dB, a VSWR of 1.23, a gain of 1.454 dBi, a bandwidth of 410 MHz, the resulting radiation pattern is bidirectional and the antenna undergoes miniaturization at a groundplane width of 18%. That way the antenna using the CSRR method can increase bandwidth and miniaturization.

The implementation of the New Normal is carried out in all aspects of community activities, to keep the body healthy it is necessary to do regular exercise. Futsal is one of the sports that is currently trending and is carried out in a sports hall, so that the futsal field building also needs to reach a new normal. In order to maintain the function of the futsal field as a healthy place, a system is needed to maintain air circulation in the futsal field. Air circulation in the futsal field needs to be controlled in order to maintain the air temperature at a certain temperature and minimize the impact of the spread of the covid19 virus by limiting the number of people in the futsal field building. The system built to realize this is by implementing air circulation control using fuzzy logic with temperature parameters and counting the number of people on the futsal field. The sensors used in this study are DHT22 which functions to measure temperature and IR (InfraRed) sensors which function as a counter for the number of people. The ESP32 module is used for sending data collected from sensor readings via the wifi network to android via the blynk application. The results of the research that has been done is that the Fuzzy control can work well, because it can maintain a temperature of no more than 31.97^oC, whereas if you don't use the temperature control it will read 32.84^oC and will continue to increase

Rancang Bangun Mesin Penetas Telur Burung Love Bird Otomatis Berbasis Arduino Uno R3

Ratna Hartayu — 2023-03-20

Caring for birds is in great demand among bird lovers both in terms of maintenance and maintenance which is quite easy, just pay attention to diet and cleanliness of the place. Birds that enter the adult mass will experience overheat, which is a sign that they are ready to be bred and ready to breed. However, problems arise when the bird does not want to incubate its eggs due to certain factors. A fully automatic bird egg incubator using Arduino UNO is needed, which is a tool that functions to incubate bird eggs automatically and perfectly without having to be incubated by the parent, with the aim of reduce the failure rate in raising birds and increase the process of hatching the eggs. This machine regulates the temperature and humidity levels as well as egg rotation so that the resulting temperature can be evenly distributed automatically without having to touch the eggs during the hatching process as a substitute for the natural incubation process by the mother. The temperature needed to incubate the eggs ranges from 37.5°C to 40°C and humidity ranges from 35% to 60%.
