Full text linkTomato plants are one of the many agricultural commodities needed by the community. Most farmers grow tomatoes in conventional ways in the fields, fields or plantations without the control and measurement relying on experience and habitual factors, so the need for pH and temperature of the planting space of tomato plants cannot be given according to their needs, while the pH requirements of tomato plants range 6.5 and the planting room temperature is 28 °C, and soil moisture is 70%, using the hydroponic planting method which is automatically controlled by the Arduino-based microcontroller with the application of fuzzy mamdani making it easy to do pH setting of planting media using soil pH sensor as input and temperature of planting room using LM35 temperature sensor, and soil moisture sensor using humidity sensor fc28, as the system output fan and selenoid valve are used. To find out plant nutrition, one of the indicators is the pH value of soil media, room temperature and humidity of the planting medium
Pembuatan Trainer Tempat Sampah Otomatis Guna Menyiasati Masalah Sampah Di Lingkungan Masyarakat: Making Automatic Trash Trainer To Get Rid of Waste Problems in the Community Environment
Full text linkNgadirejo Village is a safe and comfortable village with the majority of the population working in agriculture and animal husbandry. However, on the other hand, public awareness and concern for handling waste is still lacking. Concerns about the waste problem can be reduced by increasing public awareness to treat waste properly and correctly. Therefore, the author tries to make a tool that is an Automatic Trash Place so that the community members are not reluctant to throw garbage in the trash. They do not need to touch the lid of the trash, to open it only need to hold hands and automatically the trash can will open. Trash cans are made by modifying existing bins. Swivel-covered bins are connected by servo motors and ultrasonic and infrared sensors which are controlled by the Arduino Uno microcontroller kit. This trash can can function properly and be used properly by the community. The results of this research are that the trash can can respond to garbage that is 20 cm away quickly and the trainer is used by students of the electrical engineering study program at Balitar Islamic University as a learning medium
Prototype Sistem Deteksi Partial Discharge Pada Isolasi Kabel Menggunakan Sensor Microphone: Prototype Of Partial Discharge Detection System In Cable Isolation Using Microphone Sensor
Full text linkThe phenomenon that often arises in a substation is the problem of partial discharge in outgoing cable insulation. Partial discharge is a jump of positive and negative ions that are not supposed to meet so that it can cause a spark jump. If a partial discharge is left too long it can cause insulation failure, the sound of snakes like hissing and the most can cause a flashover on the outgoing cable. Then a partial discharge detection prototype was made in the cable insulation in order to anticipate the isolation interference in the outgoing cable. Can simplify the work of substation operators to check the reliability of insulation on the outgoing side of each cubicle. So it was compiled as a method for measuring sound waves caused by partial discharge in the process of measuring using a microphone sensor, the Arduino Mega 2560 module as a microcontroller, the LCD TFT as a monitoring and the MicroSD card module as its storage. The microphone sensor is a sensor that has a high sensitivity to sound, has 2analog and digital readings, and is easily designed with a microcontroller. Basically the unit of measure measured at partial discharge is Decibels. The results of the prototype can be applied to the cubicle and the way it works is to match the prototype to the outgoing cubicle cable then measure from the cable boots connector to the bottom of the outgoing cable with a distance of 1 meter. Then the measurement results will be monitored on the TFT LCD screen in the form of measurement results, graphs and categories on partial discharge. In this design the measurement data made by the microphone can be stored with microSD so that it can make an evaluation of partial discharge handling in outgoing cable insulation

Sistem Kontrol Governor Menggunakan Pid Yang Dioptimasi Dengan Metode Cuckoo Search Algorithm (Csa): Governor Control System Using Pid Optimized With the Cuckoo Search Algorithm (Csa)
Full text linkIndonesia has enormous potential for the Hydroelectric Power Plant (PLTA). Considering that PLTA is an environmentallyfriendly power plant, the components of this plant are worthy of further development. One of them is the development of the hydropower governoor control system. The PID controller is a control system that is often used in the control of theGovernoor System in a hydropower plant because of its simple controller. At present hydro power plants still use theconventional method of PID control trial-error on average. For this method it is difficult to adjust parameters and it takes a long time and the accuracy of controls is not good. Therefore a smart method is needed to overcome this problem.In the past few years, researchers have used many intelligent methods (Artificial Intelligent) to determine the DC PIDparameters. One of them is Cucckoo Search Algorithm (CSA) which is inspired by the behavior of cuckoo birds in placingtheir eggs. By using the CSA method, it is expected to provide a better system response than using the old system PIDcontrol (trial-error). The final goal of the PID control system used in the hydro generator is to regulate the movement ofthe turbine guide vane, which will affect the electrical power produced by the generator. Here the Guide Vane blade settingscan be likened to adjusting the angle of a DC motor. In this study a miniature prototype system governor will be createdthat is controlled by using a PID controller optimized using the Cuckoo Search Algorithm method. In experiments withthe trial error method, the Kp = 3, Ki = 1 and Kd = 10 values with the magnitude of the control parameters obtainedthe average settling time for set point 4 to set point 8 of 24.2 second. Furthermore, the CSA method is used for tuning the PID. After being tuned to the CSA method the values of Kp, Ki and Kd are different for each set point. For set point 4,Kp = 0.99, Ki = 1.00 and Kd = 0.99, while the average settling time is also better than PID trial error, which is 18.8 second
