Often car owners keep an eye on their cars parked in public places. The car is equipped with a security system from the manufacturer but it is only local or only in the form of an alarm in the car, so it cannot be heard from afar by the car owner. So we need a car security that can tell the car owner if there is a thief or break the glass where the car owner is. This IoT-based car safety device uses experiments, namely by conducting trials if there is a car thief in front of the car door. This tool uses a PIR sensor to detect human movement in front of the car door and a vibration sensor to detect vibrations at the car door. Both sensors are used to detect thieves or break cars. The microcontroller used is the Node MCU ESP8266 which will process the second input and send a message to telegram if there is a car thief. Buzzer is used as a local alarm if there is a car thief. PIR sensor can detect humans within a range of 1 meter more than 1 meter does not detect humans. While the vibration sensor will be high if there is a vibration on the car door. The response time of the MCU Node sending a message to the owner's cell phone via telegram is 6.05 seconds.

Waste is often referred to as industrial waste, some consider it as crop residue. As indicated by PP No. 82 of 2001, liquid waste is the result of an action as a fluid. Liquid waste depends on its temperament, in particular the actual and total properties, metals, inorganic non-metals, natural totals, and microorganisms. Currently the world is facing a water crisis due to polluted waste. Some organizations are not rESPonsible for dumping their waste into the sea or waterways, depriving the oceans and rivers of their capacity. Waste that pollutes waterways can destroy the clarity of the water, thus making the water concentrated and polluted with various harmful microscopic organisms from the waste. Even the river cannot be used properly because it has been polluted by waste. So that wastewater does not pollute the environment and can still be reprocessed, it is necessary to monitor the level of acidity and the amount of dissolved minerals in the liquid waste.

The survey conducted by the author shows that not all parents will see a doctor to check their child's growth and development because they are busy working and will only go to the doctor when their child is in an unhealthy condition. From the survey data in the form of questionnaires collected, some parents also do not know what symptoms affect their child's growth and development. If a child has a developmental disorder and parents rarely consult to find out how high the level of the disorder is, it will worsen the growth and development of the child so that the number of developmental disorders in children will increase. Based on the problems above, an Early Childhood Development Expert System application was built using the Forward Chaining Method and the Backward Chaining Method, the reason for using both methods is to be different from previous research and the search process can be more varied. The forward chaining method looks for disorders based on the symptoms selected by the user. The backward chaining method is used to determine the level of disorders that occur in children based on the symptoms and disorders selected by the user. The application is built using the PHP programming language and the Unified Modeling Language (UML) modeling tool. The results of the implementation of this scientific work are able to produce an early childhood development expert system application that can detect symptoms or disorders using the Forward Chaining and Backward Chaining methods. This application is ready and suitable for users to detect symptoms or disorders.</p> Sofyana Ibrahim, Debby Paseru, Vivie Deyby Kumenap Copyright (c) 2021 Hak cipta pada setiap artikel adalah milik penulis.

The training provided has a level of complexity and difficulty that is adjusted to the current conditions of understanding of the teachers through a short survey conducted at the beginning of the training where teachers will be asked to provide an overview of knowledge about Microsoft PowerPoint in a form. After that the training team will carry out training exercises from the training that will be given to the teachers and separate several training sessions to follow the progress of the results of the teachers.
