Abstract

In the current industrial era, there are many uses for utilizing AC (Alternating Current) motors which have 2 types, namely synchronous and induction. Where induction motors are often relied on in the industry for now with 3-phase induction motors. With the above problems, this article discusses the solution for instigating Star-Delta motors using automatic and manual techniques that are widely used in industry with PLC media. As for the following component specifications, such as for pushbutton ON two, special specifications are needed where the pushbutton has one NO contact and one NC contact as shown below For the main contactor (KU) requires 1 NC contact with the notation 21-22 and 2 NO contacts with the notation 13-14 and 43-44. Meanwhile, the Delta (Triangle) contactor requires one NO contact (13-14) and one NC contact (21-22). This chapter focuses on explaining the automatic and manual star delta circuits in the cx programmer and cx designer. Manual star-delta in this series the star to delta transfer is manual or you could say the change is using the action of the user. PLC CP1E is a type of PLC that is prioritized by having a low price but is still efficient by having analog input/output and being able to measure temperature. Starting the motor requires a Star-Delta circuit on the Starting Motor current. This starting is useful for reducing surge currents and also torque when starting. The Star-Delta series is equipped with interlock protection designed to overcome the possibility of “Human Error” due to negligence. Keywords: Control manual, automatic, star-delta circuit

Abstract

Flooding is a natural disaster that often occurs in Indonesia. Floods are often caused by the inability of rivers to accommodate water discharge, which is exacerbated by the handling of riverbank areas, resulting in an increased risk of natural disasters such as floods. Flood risk management is an urgent need considering the potential and pattern of disaster cycles in Indonesia that recur within a certain time interval. Flood risk management technology, both in terms of risk management technology and post-flood handling, is important for almost all regions in Indonesia. One of the technologies that can help with disaster risk management is an early warning system, which is an integrated system between hazard monitoring, disaster risk assessment, communication, and disaster preparedness that allows individuals, communities, and governments to take appropriate action in order to minimize the impact of disasters. By utilizing telecommunication networks and a simple and clear formulation of information, the dissemination of disaster information can be done quickly and precisely. A flood notification system is a system that serves as a warning and alert system in the event of a flood disaster. This system gives us a flood warning based on the water level. The brain of the prototype is the ESP8266 Nodemcu-based Wi-Fi module. In this system, it uses an SRF05 ultrasonic sensor and a water level float sensor to detect the water level. In this study, a prototype of a flood notification system that can be monitored with telegram commands was developed. Thus, access to flood information is easier and clearer. This system's information will be a warning of danger signs, allowing users to anticipate disasters, particularly flood disasters.This alert information is based on the water level.

Abstract

Technology as a means to facilitate human activities is currently being applied in various fields of activity due to its rapid development. The implementation of technology has also penetrated the field of sports as a physical activity and as a solution for human physical health. Sports progress is based on the optimal state of human resources, facilities and management. With technology in the world of sports, more advanced sports are also in harmony with existing technological developments. In other sports, technology has been utilized to support and optimize the course of the sport, for example, in football with VAR and badminton with hawk-eye. Therefore, the sport of petanque, which was first popularized in Indonesia at the Sea Games in Palembang, has the potential to develop various improvements through the use of technology. The urgency faced is at the stage of measuring the distance of the ball to decide on awarding points to the team that is entitled to a Petanque match. The measuring devices and methods used are still conventional and have the potential to produce inaccurate distance values and decisions. The accuracy of the distance measurement results obtained using conventional tools and methods is questionable and raises doubts due to various factors. With the existence of distance measurement technology, it will help the referee's performance as a Petanque match court in making point decisions. The use of the VL53L0X time-of-flight (ToF) sensor has great potential because it has the advantage of good accuracy and is not affected by noise that affects the measurement results. By using the Arduino Uno R3 as a regulatory and process microcontroller and a KY-008 laser to direct and indicate the ToF sensor right at the target object. From the tests carried out, it was found that the maximum accuracy value of the prototype reached 98.45% with a standard deviation of 3.01.
