Abstract

One of the KRI fields is the Indonesian Football Robot Contest (KRSBI). In a match the robot does not know when the ball from the robot in one team is ready to be kicked into the opponent's goal. The kicking robot has an important role in creating goals against the opponent's goal. At the KRSBI solenoid kicker, Jambi University, using a booster converter zvz 390 to charge a capacitor bank which has a capacitance of 3900 F with a high voltage of 387 V, takes 6.34 seconds. However, 387 V is the maximum booster converter voltage. To minimize the occurrence of damage, a voltage of 310 V is set as the setpoint voltage for charging the capacitor bank with a charging time span of 4.3 seconds. Then the automatic control system for charging capacitor banks has a maximum error of 1.9%

Abstract

The use of smarthome technology to monitor and control homes is growing recently. The smarthome system requires the integration of several sensors to determine the conditions in the house. In a centralized smarthome system, all sensors are connected to a single node to perform data processing and communication which can result in system failure if this node is broken. In this study, we use a distributed model for the smarthome system. The designed system consists of three nodes, which are kitchen instrument, room instrument, and door instrument. These three instruments are equipped with RFID sensors, temperature sensors, gas sensors, and reed switch sensors to perform security features of the smarthome that can be accessed remotely via smartphones or computers. The results show that the system has been able to work well and can overcome the problem of failure on some instruments without causing the whole system to collapse. This smarthome system has an average delay of 2.21 seconds.

Abstract

Stripping the betel nut using a machine is considered to be more effective than manually, based on this I designed an automatic betel nut peeler control device using Arduino Mega as a mechanical and electrical system controller. In the design of this tool using a hollow iron frame material with 40X40 mm, with a length of 130 cm and a width of 30 cm. Furthermore, this tool is planned to be able to work with a capacity of 20 Kg/hour. After all components are completed, it will proceed to the tool development process to be able to perform performance tests. After testing, stripping using the manual method takes a relatively longer time, which is 11 minutes. While using the machine only takes 6 minutes. In this test, 1 kg or 74 young betel nut, yellow areca nut, dry areca nut, and wet old areca nut were used.

Abstract

This research aims to design a measuring device for the speed and strength of kicks and punches in martial arts so that the quality of kicks and punches can be measured objectively. The types of taekwondo kicks that were tested were ap chagi and yeop chagi as well as yeop jireugi and momtong jireugi punches. This research was conducted in several steps, namely: literature study, preparing tools and materials, designing and modeling, making tools and testing and analyzing data. The way this tool works, the respondent kicks or punches the foot boxing pad that has the FSR sensor installed. At the same time the time is started by pressing the start button. After making a kick or punch, the time will be stopped by pressing the stop button. The pressure and time will be read by the NodeMCU ESP32, the data will be sent via bluetooth to the Blynk application and displayed with the TM1637. The results of the research "designing a measuring device for measuring the strength and speed of kicks and punches in martial arts with a force sensing resistor (fsr) sensor and NodeMCU ESP32" are: The average kick speed of ap chagi and yeop chagi is 0.10625 m/s and 0.0786 m/s. Meanwhile, the average speed of yeop jireugi and momotong jireugi are 0.1667 m/s and 0.0917 m/s, respectively. The average athlete has a kick power of ap chagi, yeop chagi, yeop jireugi and momtong jireugi is medium.
