Abstract

Automatic doors are generally developed by RFID cards or use cards with barcode labels. According to [1] the weakness of RFID is that the reading distance of the RFID Card is around 5 cm. According to [2] cards with barcode labels still have weaknesses such as barcode labels that are scratched, so that it cannot be identified. From RFID and barcode labels weaknesses, then an automatic door was designed using Arduino Uno with the Bluetooth module and controlled using an application on a smartphone instead of a card. Automatic doors with Android-based smartphone locks have several advantages, namely the ease, practically and relative security of losing keys. This technology is not yet commonly used by the people of Indonesia and is expected to be an alternative going forward as a solution in applying the concept of housing with smart technology. The purpose of this study is to design an automatic door using a Bluetooth signal connection and analyze the signal strength connected with a smartphone. The Bluetooth module used is the HC-05 module which operates at 2.4GHz frequency. According to [7] to produce a good Bluetooth connection, it is necessary to control and filter noise. The method in this research is to design an automatic door and then analyze the signal strength and signal range from the smartphone to the door. Smart home-based door systems with Android smartphone door locks can be used normally up to 9 meters and are considered sufficient for the size of a house in general.Keywords: automatic door, RFID card, Arduino Uno, bluetooth, smart home

Abstract

The problem faced by the Annuqayah Vocational School curriculum is the same schedule and is taught by the same teacher. Such problems are quite complex problems because they relate to the number of teachers available. The lesson schedule is presented in the form of day and class hours tables. The subject can be seen that every day schedule divided into time slots. Each time slot has a list of subjects taught by the teacher in a particular room. To optimize the lesson schedule in Annuqayah Vocational School, Genetic Algorithm is used. This algorithm is a computational approach to the principle of natural selection, Charles Darwin's theory of evolution and the theory of Mendel's inheritance [1]. The optimization process in Genetic Algorithms includes individual generation, evaluation of fitness values, determination of probability values, Roulette Wheel selection, crossover, mutations, and new individual generation. Scheduling optimization using the Genetic Algorithm approach was declared successful because it was able to find the right combination of scheduling with optimal fitness values in 10 attempts, and no violations of the established rules from the curriculum were found so that it could assist in the preparation of subject schedules in Annuqayah Vocational High School.Keywords: curriculum, Vocational High School, scheduling, Genetic Algorithm, optimization.
