Abstract

Abstract: Technological developments also affect the progress and motivation to read the book. One technology developed in the field of electronics is an effort to increase interest in reading. With the tool Design Building Page Flipper Automatic Book Using Microcontroller ATmega328P then can make an alternative to open the book sheet. In addition, this tool is also appropriately utilized by people with special needs or have physical limitations (hand disability). With this tool can make it easier for someone to read a book because it is designed using an automated system. The automatic book page flipper tool uses an ATmega328P Microcontroller 4 servo motors where the servo motor 1 moves 100° to lower the lever on the drive wheel with a time delay of 1 second along with the operation of servo 2 which is marked by the movement of the wheel rotating 100° so that the book sheet or file is slightly attracted by the 1 second delay, then servo 3 moves which functions as a hold for the book or file sheet with a 100° movement, with a time delay of 1 second and servo 4 moves 180° as the thrower of the book sheet or file. And the sound sensor functions to give commands to the ATmega328P microcontroller which will later give orders to the ATmega 328P microcontroller which will later drive all the servo motors when getting commands.   Keywords: Microcontroller, sensor, servo motor

Abstract

Fire is something that occurs as a result of a fire that is not handled properly and quickly. This incident is very dangerous considering the potential to cause material losses and loss of life. Various fire detection systems have been developed to detect and prevent fires. So far, many kinds of research on fire detection use fire and smoke sensors, and others, but that alone is not enough. It takes a tool that can detect a fire at the same time and know-how the conditions are when a fire occurs. With the development of technology, the use of computer vision is used to detect fires in real-time. Besides being able to detect fires, the system can also provide an overview of the current state of the fire through the camera. In this study, a computer vision-based fire detection was designed. Where it uses the You Only Look Once (YOLO) algorithm to detect fires and is accompanied by telegram notifications and buzzers. In the fire detection test, 4 different fire sources were used, namely small torch candles, large torches, and coconut fiber. From the test data for fire detection in various backgrounds, the accuracy value is 0.8, precision is 1 and recall is 0.8 during the day. While at night, the accuracy is 0.96, precision is 1 and recall is 0.96. The level of accuracy and recall values ​​in testing various distances results in a fire detection system that will decrease as the distance between the fire and the camera is far away. The precision value produces a value of 1 at various distances during the day and night. That means the accuracy of the classification results is 100%. The stable precision value is influenced by fire detection readings, where the system never detects other objects as fire.

Abstract

This automatic water filling and bottle closing system can usually be used in the industrial world, because it can facilitate and save processing time. For this reason, an automatic water filling machine was made to produce packaged drinks that are practical and easy to obtain. In this machine, there are components that play an important role in the operation of this automatic machine, including the Programmable Logic Controller (PLC) which is a control device that can be programmed logically, accepts input, and provides output. In the manufacture of this automatic water filling and bottle closing device, 4 sensors and 1 limit switch are used, each sensor has its own function. The 4 (four) sensors include: conveyor sensor, rotation sensor, bottle closing sensor and reset sensor. The limit switch on this tool functions as a stop motor rotation when the bottle is closed. After several experiments, it took 13 seconds to fill a bottle with a capacity of 600 ml.
