Abstract

Fish farming in general is a cultivation that is in great demand by Indonesian people. Discussing actions that can facilitate the maintenance of fish cultivators, for now fish feed is still mostly done directly by fish owners. Late feeding can affect the pond ecosystem, the appearance of cannibalism in fish and abnormal fish weight. The application of IoT technology is expected to make it easier for fish farmers, especially for pond areas and ponds, to provide feed when outside the city. The technology that will be applied is an automatic fish feeder that can be adjusted according to the fish feeding schedule automatically and can also monitor feed conditions through the Blynk application on a smartphone. The electronic components used are the ESP8266 as a data processor, the MG996R Servo Motor as the feed tap driver, the SG90 Servo Motor as the Potentiometer drive, the Potentiometer as the active control of the Blower, the Blower as the spreader of fish feed, the Ultrasonic Sensor HY-SRF05 as monitoring of feed conditions, the Power Supply as 12 V voltage input, Buzzer as an alarm notification and the Blynk application on a smartphone. The test results show that the built tool can function properly, setting the feed schedule and monitoring the feed runs normally according to the instructions set in the Blynk application.

Abstract

The availability of data loggers as data acquisition is still limited to sensor levels and the data loggers have not been produced in Indonesia. This makes it difficult for monitors to obtain data such as water pressure and water discharge data. The solution to this problem is to reduce the import cost of purchasing data loggers from abroad by developing data loggers that are able to take data on water level, water pressure. This study aims to determine how the design and performance of data logger system substitution products flow and water pressure using LoRa WAN communication. The test results show that the Water Flow and Pressure Data logger System functions according to the design that has been made with error readings from the itron cyble sensor of ?? and a pressure sensor reading error of 20.66%. The Packet Loss value of sending data from the data logger device is directly proportional to the distance where the smallest packet loss value is 13% at a distance of 50m and 80% at a distance of 2800m.

Abstract

As time goes by, agricultural land in urban areas has decreased. Aquaponics can be an option for agricultural development in urban areas. However, in the field, there are obstacles where the condition of the fishpond water is uncertain in providing nutrients for the plants. To respond to this condition, this research developed a system by implementing an IoT system that is integrated with a rule-based control system to control and monitor nutritional quality by the needs of aquaponic-based plants. This technology includes controlling pH levels, water temperature, and TDS (total dissolved solids) produced by fish waste in the aquaponic system to be used as nutrition for plants. This system requires several sensors and main components, including a ph meter sensor, TDS, and temperature sensor, which are integrated and processed via the ESP32 microcontroller. The system measurement results are controlled and sent to the IoT Cloud database connected by an internet connection. This IoT-based aquaponics system can be monitored in real-time. The test results on the system show that the sensors used have a small reading error, namely the temperature sensor showing an error value of 1.5%, the PH sensor 0.7%, and the TDS sensor 0.9%. In this way, the level of accuracy when using sensors can be guaranteed. The research results show that the control and monitoring system design works according to needs, where the system that is controlled and integrated with the website system can run with a 100% success rate, which can facilitate the care and maintenance of plants and fish by farmers.

Abstract

Horizontal axis wind turbines will generate voltage if the turbine rotates due to wind gusts. The bigger the wind blows, the faster the turbine spins and the greater the voltage generated. The braking system is needed for wind turbine protection when it receives very large wind speeds. This system is built using PID control based on microcontroller with reference to the output voltage. There are 2 units resistor designed as voltage sensors to the wind turbine output voltage. In testing, the wind turbine is rotated using artificial wind which is generated through a blower measuring 1.3 x 1.3 x 0.3 m, with a maximum wind speed is 11 m/s. The sistem uses PID kontrol which is used to brake wind turbine rotation and regulate its output voltage. Determination of constant parameters for proportional constant (Kp), integral constant (Ki), and Derivative constant (Kd) were obtained for Kp = 0.139, Ki = 0.715, and Kd = 0.006 respectively. The output voltage of the wind turbine can reach 60 volts and then controlled up to 24 volts according to the battery voltage requirements. In the test results, the control system managed to regulate the wind turbine voltage at 24 volts with a steady state error of 6.62%

Abstract

Traffic jams have become a serious problem in many countries, including Indonesia. Traffic management is a challenging task, especially in developing countries. One of the causes of traffic jams is long lines of vehicles at intersections because the traffic light signals are on at the same time without paying attention to the number of vehicles queuing. The computer vision approach can be applied as a solution by minimizing waiting time for drivers by adjusting the length of time the green light signal is on based on the number of vehicles in each lane. To carry out this approach, a vehicle detection system was built using the YOLOv8 (You Only Look Once 8th version) algorithm, which operates in real-time. The data used comes from CCTV installed at every traffic light at intersection four. The YOLOv8 algorithm shows high accuracy and efficiency in object detection in various studies. To find out to what extent the YOLO model that has been built can predict the data correctly, it is necessary to evaluate the model by calculating accuracy, recall and mAP50 score. This research aims to build an intelligent traffic light management system using YOLOv8, based on computer vision and the OpenCV library. The results obtained from this system calculation are an accuracy value of 0.689, a recall value of 0.578, and an mAP50 score of 0.65.

Abstract

To ensure the continuity of electrical energy distribution when using an Off-Grid PV system, overcoming the challenges posed by its intermittent nature is necessary. This requires the use of more than one source of electrical energy. This involves the use of more than one source of electrical energy. A device known as ATS and AMF facilitates switching between energy sources. This research aims to design an ATS equipped with AMF to transfer three electricity sources: Photovoltaic system, PLN, and Genset for a single-phase system, with the main control device being PLC. The test results found that the transfer time from the PV system to PLN is 39ms, while the transfer time from the PV system to the Genset or from PLN to the Genset is 5s. This transfer time includes the process of starting and warming up the generator. In this system, if the Genset is displaced to PLN or PLTS, the transfer time is 39ms. The starting of the generator set is limited to three attempts. If the generator set fails to start or is not voltage detected, the system will consider it a starting failure, indicated by the active Buzzer.
