Abstract

Management of feeding and drinking is the key to the successful development of laying hens. Food left in the coop will be damp and a source of viruses so that the chicks can contract the disease. Lack of drinking can disrupt the growth of chicks because the amount of drinking determines the amount of food consumed. The feeding system is carried out at the same time every day, namely at 07.00, 15.00 and 21.00. Feeding is also given according to the needs of the chicks based on the age of the chicks. Meals are weighed using a loadcell sensor which is located where the chicken feed container is in the cage. The actuator used in the feeding system is a servo. The drinking system is carried out when the water in the container in the cage runs out. To detect the water level in the container in the cage, the HC-SR04 sensor is used. The actuator used in the drinking system is a DC water pump with a relay as an automatic switch. Water in the cage is provided throughout the day. All systems are controlled using the ESP32 microcontroller. Keywords: Laying Chicks, Feed, Drink, Loadcell, HC-SR04

Abstract

Yogurt is a food product that is widely consumed. The manufacturing process is by mixing the Lactobacillus bulgaricus and Streptococcus thermophilus bacteria into milk and proceed with the incubation stage. In the incubation process, the temperature of the milk must be carefully maintained with a normal time of around 16 hours in order to produce a good product. This makes yogurt producers quite difficult because they still use manual methods. Therefore, a water temperature control tool was made in this yogurt incubation process. This tool works by placing milk that has been treated with bacteria in a container surrounded by water. The water temperature will be maintained so that the temperature of the yogurt is maintained. Temperature control is carried out using the PI control method to make it easier for yogurt producers to carry out the production process. The ziegler-nichols method is used to obtain Kp and Ki parameters. Based on the test results, the PI control can control the water temperature well with the parameters Kp = 49.87 and Ki = 0.033. The response of the testing system for controlling water temperature in the yogurt incubation process with a yoghurt temperature setpoint of 45°C obtained that the water temperature reached steady state at 12771 seconds with an overshoot of 4.8% and a steady state error of 1.6%. For the yogurt temperature value to reach steady state occurs in the 6594th second with a steady state error of 4.1%. In the yogurt incubation process which lasted for ± 10 hours, it was found that the temperature difference between the water and yogurt was an average of 1.63°C. Keywords: yogurt, temperature, PI control, ziegler-nichols

Abstract

Combining Solar power plants electricity sources with PLN electricity sources is expected to save electricity bills because electricity needs are met by two electricity sources, can anticipate the lack of Solar power plants electricity supply, and can anticipate blackouts from PLN electricity sources. For this reason, an automatic control system is needed to switch electricity sources. The control system is the Automatic Transfer Switch (ATS). ATS is equipment that can transfer loads from PLN electricity sources to Solar power plants electricity sources or vice versa automatically if there is a disturbance in one of the electricity sources. This research designs an ATS that is equipped with synchronisation of two power sources using the zero-crossing detector method. The components used are Arduino Mega 2560 Pro Mini as a microcontroller, a voltage detector to detect the voltage of the power source, and 4 10A relays as switches for switching power sources. The result of this research is that there is no delay and wave difference in the load when there is a switch from the PLN power source to the inverter or vice versa. Another condition is that when the PLN power source goes out, the ATS will move the power source automatically to the inverter by only requiring a delay of less than 7 ms to reconnect the power source with the load. Keywords: PLN power source, Solar power plant, ATS, synchronisation.

Abstract

Aeroponics is a method of growing plants in a hanging root position and providing water and nutrients by misting the roots of the plants. In this research the authors designed a system that can condition the environment in a greenhouse using aeroponic growing media with parameters of air temperature, air humidity, and light intensity. In this design, the DS18B20 sensor is used as a temperature detector, the DHT11 sensor as a humidity detector, and the LDR sensor as a light intensity detector. The results of the DHT11 sensor test compared to the HTC-2 thermometer obtained an average error of 2.77%, the DS18B20 sensor test compared to the HTC-2 thermometer obtained an average error of 3.34%, the LDR sensor test compared to the AS803 luxmeter obtained errors that vary each test. The measurements results from the sensor will be processed by Arduino Uno and Single Board Computer to control the actuator connected to the relay. In this system to condition the environment, there are air temperature parameters controlled using a DC fan, air humidity controlled using a mistmaker and lighting controlled using an LED grow light. This environmental conditioning system is capable of lowering the temperature by 0.5°C with an average length of time of 2:18 minutes, increasing the air humidity by 5% RH with an average length of time of 4:20 minutes, and turning on the LED growlight when the light intensity is low. of 50lux according to the program. The automatic watering system in the form of mist uses an Arduino Uno timer with a water pump and a 0.3mm nozzle. From the results of sensor testing and the results of testing the environmental conditioning system, it shows that the designed system can work well according to the expected design. Keywords: Aeroponics, greenhouse, lighting, temperature, humidity, watering

Abstract

Electricity is an energy that is highly demanded by all of mankind. In Indonesia, the consumption of electricity increases every year. Therefore, there is a need for power plants that can supply the increasing electricity demand year after year. In 2020, out of the 65,236 MW generated by power plants in Indonesia, a total of 90.75% of the electricity in Indonesia was still supplied by fossil fuel power plants. In 2021, PLN (State Electricity Company) experienced a coal supply crisis due to extreme weather conditions in coal mining areas, delays in the coal procurement process, and the impact of coal export prices. This coal supply crisis resulted in20 coal-fired power plants with a capacity of 10,850 MW being at risk of blackouts. This highlights the importance of renewable energy power plants to reduce dependence on fossil fuels. The government is also striving to achieve a 25% utilization of renewable energy by 2025, including solar power plants. In electricity production, solar power plants rely heavily on solar radiation that can be captured by solar panels. Solar radiation on the surface of solar panels is a fundamental parameter for designing a well-integrated photovoltage (PV) system, both for load requirements and determining the amount of electricity produced by the panels, as well as for accurate operational simulations. Therefore, AI is expected to be used to assist in theanalysis of solar radiation. AI has advantages in certain tasks, making it possible for computers to make accurate decisions that result in more efficient operations. AI is highly suitable for processing solar radiation data in a particular location, especially considering the years of collected solar radiation data that form big 2 data. The use of artificial intelligence and big data can analyze the data and provide faster insights compared to conventional mathematical calculations. By employing various deep learning algorithms such as vector autoregression (VAR) and long-short term memory (LSTM), the prediction of solar radiation can become more accurate, facilitating optimal analysis in the design of solar power plants for households and industries. The AIalgorithm used for solar radiation prediction in this study is a combination of VAR and LSTM algorithms. The accuracy rate achieved by the combination of VAR and LSTM algorithms in this research exceeds 90%, indicating that this combination is highly suitable for predicting future solar radiation. Keywords: solar power plant, artificial intelligence (AI), solar radiation prediction.
