Abstract

Aquaponics is an agricultural system that combines fish and plant cultivation in one closed system. In an aquaponics system, the water used for fish cultivation is also used to irrigate plants with rice aquaponics as one example. However, monitoring and controlling aquaponic systems is still done manually, which has many shortcomings, including requiring a relatively long time and accuracy that is not guaranteed, especially in large-scale aquaponics management. Implementing the fuzzy algorithm in the rice aquaponics control system aims to make it easier for farmers to monitor the condition of the rice and control the water change system in the pond in real time via the Blynk application on their smartphone. This system combines ESP-32 technology, fuzzy algorithms, and the Internet of Things (IoT) to monitor and control the rice aquaponics system. The results of data collection from the implementation of the fuzzy algorithm in the rice aquaponics control system show that the tool functions well. This tool can monitor the condition of rice and control the water change system in the pond in real time using the Blynk application. The level of accuracy of implementing the fuzzy algorithm for monitoring rice conditions was 99.61% and the accuracy of implementing the fuzzy algorithm for pump control of the water change system was 98.95%.

Abstract

Robotic-based sorting systems offer an innovative solution to enhance efficiency and accuracy in the logistics industry. This research aims to design and implement a robotic system capable of automatically sorting goods by integrating barcode scanning technology and line tracer navigation. The system is built using an Arduino Mega 2560 as the main controller and is equipped with Stepper motors, DC motors, mecanum wheels, a GM65 barcode scanner, and various supporting actuators.Experimental results show that the GM65 sensor can optimally read barcodes at distances ranging from 15 to 55 cm. The servo motor demonstrates an accuracy rate of over 98%, while the Stepper motor performs optimally at a minimum voltage of 9.0 V. Additionally, line sensor calibration yields a threshold range between 528 and 573, ensuring accurate line detection. The system also exhibits stable movement with consistent speed and minimal travel time variation, indicating efficient operational performance.By integrating these technologies, the developed robotic sorter system significantly improves productivity, accuracy, and reliability in automated goods sorting processes. The implementation of this system is expected to support automation in the logistics sector and provide a practical solution to distribution management challenges in the era of Industry 4.0.

Abstract

The wind is one of the new renewable energy sources that can be used as a source of electrical energy. But the wind in nature has a speed that varies greatly with each time and place. This can be overcome by using the DC-DC Converter tool with a fuzzy method to produce a stable electrical voltage so that it becomes usable electrical energy. This tool uses a series of converters connected to the Arduino microcontroller. The DC-DC converter circuit in this study also uses a voltage sensor as feedback for the Fuzzy method to maintain the stability of the circuit output which varies from 2V-5V, so that it can maintain a voltage of 6.5V which is used as a 6V battery charging. This circuit has an average efficiency of 60% for the open-loop system and 63% for the closed-loop system.

Abstract

Indonesia is a country that has two seasons, namely the summer and the rainy season, when the rainy season arrives, the rainfall will be very high which can cause flooding. This can be overcome by technological innovation in the form of tools that can work in real-time to detect the condition of water flow in rivers so that losses due to flooding can be minimized. This tool uses a level sensor with the float magnetic level gauge method which is connected to the ESP32 microcontroller module as a sensor data controller and sends the sensor measurement data values ​​to the IoT platform. The sensor measurement results correspond to the water level in centimeters and are sent to the IoT platforms, namely Blynk and Telegram in real-time. The results of sending data to the Blynk and Telegram applications have an average error value of 1.5%.

Abstract

Garbage is a material left over from human activities which is an environmental issue and causes environmental pollution. Humans themselves are lazy to throw garbage in its place or are accustomed to littering, causing garbage to be scattered everywhere which in turn can cause garbage pollution, unpleasant odors and in the end can cause flooding. In this study, we will make a tool to sort organic and inorganic waste along with an Arduino-based SMS notification, namely by making a tool to sort out the types of organic waste and inorganic waste types which will later be classified separately and collected in their own place so that the waste is not mixed. To distinguish organic and inorganic waste using a capacitive proximity sensor as a separator of organic waste, an inductive proximity sensor as a separator of inorganic waste, arduino nano as a microcontroller to run all the work of the tool system. Servo motor as a sorting drive. GSM SIM 800l module as a sender of SMS notification of garbage that has been successfully sorted.

Abstract

Robotic arms are a type of robot that is currently developing rapidly in industry, this has caused robotics technology to become one of the mandatory subjects taught in universities. In the Undergraduate Department of Electrical Engineering, Faculty of Engineering, Tadulako University, the robotics course is a mandatory subject studied by students, especially students who take the weak current concentration (TEN). This research aims to provide students with an understanding of how to control a robot arm. The design of a robot arm system with 4 degrees of freedom is made using several types of control such as control using Arduino IDE software, push buttons and potentiometers. The results of testing the robot arm trainer after controlling it with three types of control were successful. In the first control using the Arduino IDE software control it shows that the direction of rotation of the motor rotates according to the program target given, in the second control using a push button it shows that the speed and acceleration are directly proportional to changes in motor degrees, then in the third control using a potentiometer it shows that the degree mapping on the potentiometer is directly proportional to the degree of the stepper motor. However, in the test there were differences in degree values ​​when the motor rotated which caused the resulting data to be inaccurate. This is due to a mismatch in tooth size between the belt and the stepper motor gear, causing wear on the belt.

Abstract

Electrical energy is a primary need in modern life that continues to increase along with the rapid development of technology and the use of portable electronic devices. Dependence on conventional power plants sourced from fossil fuels is considered unable to meet energy needs when outside the conventional electricity grid. Therefore, a more flexible and easy-to-produce renewable energy alternative is needed. One solution that can be offered is the use of piezoelectrics, which are capable of producing electrical energy only through mechanical pressure without relying on weather conditions such as solar power plants or wind power plants. This study aims to design and test a portable power generator based on piezoelectrics. The piezoelectric circuit is designed with a series-parallel configuration of 30 piezoelectric pieces, which are connected to rectifier diodes, elcos, storage batteries, and step- down modules for voltage adjustment to electronic devices. The test results show that the device can produce an output voltage of up to 32.47 VAC. Then, the highest DC voltage is 87.3 VDC. The voltage stored in Elco is 24.92 VDC, with the final output on the battery being 13.69 VDC and a current of 1 A within 2 minutes. Meanwhile, the time required to charge 1% on a mobile phone is 9 minutes, indicating the potential effectiveness of the device with further pressure increases.
