Abstract

In this paper, the efficiency of photovoltaic panels is improved by adding two solar tracking systems. The solar tracking system is used to track the sun so that the photovoltaic always faces the sun. This system uses a dual axis consisting of a horizontal rotation axis and a vertical rotation axis. The motion of the horizontal axis of rotation follows the sun's azimuth angle from north to south. The motion of the vertical axis of rotation following the sun's azimuth angle from east to west is the vertical axis motion. Both types of movement are controlled using PID and Fuzzy controllers which are optimized with an artificial intelligence approach, namely Ant Colony Optimization (ACO). Experiments with PID control approach and CES control were optimized using the ACO method (Hybrid PID-CES-ACO method).   In this research, PID-CES-ACO was the best model, obtained on the horizontal axis of overshot 1328 pu, the smallest undershot was 0.116, and the fastest settling time was 0.183 s, on the vertical axis the smallest overshot was 1.246 pu, the smallest undershot was 0.044, the fastest settling time was 0.163 s

Abstract

The control of rat pest in rice nurseries to obtain increased production continues to be done. In an effort to overcome the problem of rat pest various alternative controls have been carried out, both in technical culture, physical mechanics, and chemically. To reduce the undesirable effects of using chemicals to control rat pets, it is necessary to use other alternative rat pets control. Based on these problems, this study conducted various test to create a design that could be used to repel rat pests. The method used includes electrical and systematic design. The steps taken include the sate of literature study then designing, manufacturing hardware and software integrating the system and testing and analyzing the system. Considering these theories, it can find out the programming of microcontrollers, LDR sensors, Cameras, Internet Networks, NE555, Solar Panels, and Accu.This study uses several tests, including testing the LDR sensor, Camera, Internet Network, NE555, Solar Panel and Accu. LDR sensor is functions to detect rat objects, cameras to take video directly, internet network to send video from the microcontroller to the user, NE555 to emit ultrasonic soungd waves to repel rat pests, solar panels as a source of electrical energy, and accu as electrical energy storage that produced solar panels. From all of test above we get results when the LDR Sensor detects a rat then the NE555 will emit ultrasonic waves, then the camera sends video via iot to usser.

Abstract

Safety is a necessity in any case, as is driving. Many motorists today ignore safety in driving. Based on this innovation is needed in driving safety, automatic steering cars can be one of the driving safety solutions. This is because the automatic steering car uses a technological approach from various aspects ranging from deep learning, computer vision, sensor fusion, localization, control, unit path planning. In this discussion, the implementation of the line detection algorithm uses the hough transform and power steering methods. The results of the application of this method require a method to recognize the road markings with other things that are symmetrical in shape like a line, can be a shadow of a pole, a road divider, and so forth. Because the parameters of this method can only be used in ideal conditions. The overall application of this method successfully detects road markings with an accuracy of 75%

Abstract

To save energy nowadays is recommended to switch to renewable energy sources. In Indonesia, solar energy is abundant, so PLTS is made. The supply of PLTS is expected to reach maximum use. However, solar panels have many obstacles such as variations in temperature and sunlight intensity, MPPT systems are needed to find the maximum power point of the solar panels. Unfortunately, in Indonesia, the sunlight of short duration with the ideal irradiation time that can produce electricity from solar panels is 4 to 5 hours per day, so a PLN supply is still needed to support the continuity of the power supply. Because two sources are used, there is a problem where the load needs high continuity during power switching, so STS (Static Transfer Switch) is used for very fast power switching. Simulation results, when using EMR (Electromechanical Relay) the power transfer process takes 50ms or 5 cycles while STS takes 2ms or ¼ cycles. With very fast response to STS, sensitive equipment is kept safe from power quality disturbances such as voltage sag and voltage swell.

Abstract

As a security for land traffic in the area of railroad crossing in general, a crossing is required. Increasingly busy traffic, the number of railroad crossings today, to prevent accidents either due to human error or the lack of compliance by motorists with traffic regulations, a controller that can regulate the flow of traffic at the railroad crossing is needed. The research objective was to design an automatic railroad crossing controlled by Arduino with the C language programming command. This research will make a prototype of the Automatic Crossing Gate using the halls effect A3144 sensor as an on and off switch by detecting the presence of a magnetic field (Lorentz force) on a passing train. The stages of the research method are: Provide the necessary components, namely Arduino, bread board circuit board, buzzer, A3144 sensor, LED, servo motor as a latch dynamo, Make programming tests on the Arduino for each buzzer, LED, A3144 sensor, servo motor as a latch dynamo, Assembling the overall components on the bread board as a model, Make overall programming on the Arduino from the circuit, and test the circuit on the bread model board,  Assemble the prototype clearly with a mini train accompanied by a rail with a loop in the form of a track, Test the maximum distance, the effective distance between the A3144 half effect sensor and the train.
