Abstract

At this time, almost all Public Street Lights (PJU) still use the type of mercury and SON-T lamps, even though the mercury and SON-T lamps absorb a considerable amount of electricity. Public street lighting is usually on almost all nights, and this is a waste of electricity. Public street lighting is usually on most nights and thus is a waste of electricity. Usually, when it is past midnight, the streets are quiet, so the street lighting should be reduced in intensity to save electricity.  Based on this problem, this research uses an experimental method (Experiment) to create a design to make efforts in saving electricity. The method used includes electrical and systematic design. The steps taken include the stage of literature research, designing, manufacturing hardware and software, integrating the system, and testing and analyzing the system. Considering these theories, we can know the programming of the microcontroller ATMega 328, Photocell Sensor, PIR Sensor, LED Lights, and Power Supply. This research using several tests, including testing Photocell Sensor, PIR Sensors, LDR Sensors, and LED Lights. Photocell sensor to detect conditions day or night. PIR sensor functions to detect movement, LDR sensor to detect movement, LED lights are used to increase and decrease light intensity. For all the tests above, the results obtained when the PIR and LDR sensors have not detected any movement will dim the intensity of the LED lights. After the PIR and LDR sensors have detected the movement of the LED lights, they will turn automatically bright.

Abstract

The use of electric power is significant to supply water pumps which are usually obtained from PLN electricity. The utilization of electricity from new renewable energy such as solar panel electricity and water turbines has not been used too much to cultivate hydroponic plants. Therefore, combining electric power (hybrid) between solar cells and water turbines is needed to supply electricity on hydroponic technology in conserving electrical energy for the future. Based on these problems, this study conducted various tests to create a design that could be used for energy use in hydroponic plants. The method used includes electrical and systematic design. The steps taken include the stage of literature study, designing, manufacturing hardware, integrating the system, and testing and analyzing the system. These theories can discover solar panels, solar chargers, battery endurance, thief joule circuits, and water turbines. This study uses several tests, including solar panels, solar chargers, battery endurance, thief joule series, and water turbines. Solar panels function to capture sunlight, solar chargers to store electrical voltage to batteries, battery endurance functions to find out how many batteries can store electricity, a series of thief joules to increase voltage, and water turbines to produce voltage. From all data tests, solar panels and water turbines are a source of voltage that the battery will store via a solar charger, and then from the battery, it will be supplied to the hydroponic circuit as a source of voltage.

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.
