Abstract

Nutritional health in cockatoo maintenance is still a major problem that has not been resolved properly. Common causes of this problem include a lack of variation in food, drinking and vitamins which can affect both the physical and mental health of cockatoo. Another factor is that the keeper is not always around the cage, so that the pattern of nutritional intake is not properly monitored. In this final project research designed an automatic feeding and drinking device based on IoT, which aims to control the variation of bird feed and provide feeding remotely. Automatic feeding and drinking equipment is designed using Arduino mega2560, weight sensor (Load Cell), servo motor, relay, mini water pump, NodeMCU and RTC (Real Time Clock). The weight sensor (Load Cell) aims to check the mass of the feed, vitamin and drink containers. NodeMCU will communicate the hardware interface with the operational system automatically with the On-off control system to open the valve. The bird's dietary habit will be in accordance with the wishes of the keeper which is set in the system program on the Arduino Mega2560. Testing the whole system that works automatically gets data that there is a difference between the reference mass value of 35 grams and the results of the circuit test. The average percentage of these errors is container A of 5.11%, container B of 1.57%, container C of 2.1%, and container D of 0.05%. The data resulting from the amount of food will be sent to the BLYNK application as a monitoring system. With this IoT technology, breeder can provide food, drink and vitamins remotely.

Abstract

Generator set (Genset) is a device that can convert mechanical energy into electrical energy. In a generator et that operates to supply electricity to a load, the amount of electric current that occurs will cause an increase in heating that occurs in the engine and if not maintaeined it may cause overheating. This paper discusses the automatic generator set temperature control system to prevent overheating conditions on the generator set while operating. The control system used is the ESP-32 microcontroller with algorithm Proporsional Integral and Derivative (PID). The DS18B20 temperature sensor is used to detect the actual temperature on the generator set. As an actuator in regulating the tempreture of generator set, a 12 Volt dc fan is used. The way the temperature control works starts at the ds18b20 temperature sensor detects the temperature on the data is processed with the PID algorithm by the ESP-32 microcontoller to produce a PWM value which will be fed to the 12 Volt dc fan as an actuator. Based on tests that have been done by giving variables to Kp, Ki, Kd in order to produce a stable system response, it is obtained with the variable value Kp=2, Ki=5, Kd=1 set point 57 oC, the value of the rise time is 35 seconds, overshoot 2.19 oC, settling time 109 seconds and steady state error of 0.44 oC. In another test at the setpoint of 70 oC with variable values Kp=3, Ki=2, Kd=2, the value of rise time is 47 seconds, overhoot 2.06 oC, settling time 114 seconds, steady state error 2.31 oC.

Abstract

In this paper examines the power generation tool using piezoelectric sensors to produce electrical energy sourced from kinetic energy, where the parameters observed are controlled voltage, power, and MPPT design that is made. This study aims to determine the MPPT system commonly used in solar cells to be able to work on different systems using piezoelectric sensors. The system consists of piezoelectric sensor, rectifier circuit, DC-DC converter, PWM, and microcontroller. The discussion of the problem is focused on making renewable energy using kinetic energy through piezoelectric sensors whose voltage will be controlled using the Maximum Power Point Tracking (MPPT) method. Based on the system designed, a piezoelectric output voltage is obtained which is very small, and storage is carried out on the capacitor to obtain a voltage of 3 volts. From this voltage, the MPPT method can’t be done because the voltage on the piezoelectric has decreased dramatically when connected to the DC-DC converter. To get a 3 volt voltage at a mass load of 50 kg it takes 482 seconds with a change in voltage increase of 0.0062 per 1 second, at a load mass of 60 kg it takes 453 seconds with a change in voltage increase of 0.0066 per 1 second, and at a mass of 70 kg it takes 345 seconds with a change in voltage increase of 0.008 per 1 second.

Abstract

The use of conventional water taps for ablution is still very common, although there are many deficiencies in it. One of the drawbacks is that the valve opening on conventional faucets cannot be adjusted automatically so that the water that comes out of the faucet becomes inefficient. In this final project, a water discharge control device is designed in an automatic ablution faucet system using a microcontroller to make water use more efficient during ablution. Control of water discharge in the automatic ablution faucet system uses the HC-SR04 ultrasonic sensor which functions to read the distance of human hands / feet from the ultrasonic sensor. The way the water flow control works in this automatic ablution faucet system is that the valve opening can be adjusted automatically based on the reading of the ultrasonic sensor on the human hand / foot, then the distance detected by the ultrasonic sensor will be sent to the microcontroller which then gives commands to the servo faucet motor. Based on tests that have been carried out 15 times the process of ablution, this automatic ablution faucet system uses 24.05 liters / second of water while the conventional ablution faucet system uses 34.8 liters / second of water. So that the water efficiency obtained in the automatic ablution faucet system against the conventional ablution faucet system is 30.4%.
