AT PT JAYASEGAR BERKAT MANDIRI, AUTOMATIC KEY SYSTEM BASED ON Arduino UNO

Abstract

Security is a very important thing that must be owned by everyone including a company to protect assets and data owned. However, the conventional security sistem is still a security sistem that is still widely used even though this sistem has a very low level of security and is considered less practical, including PT Jayasegar Berkat Mandiri which still uses conventional security sistems. On the other hand, technology is developing very rapidly in all fields, including in the field of security, this is evidenced by the many security sistems that use microcontrollers and passwords have been found. From these problems the author tries to create a security sistem using a microcontroller as a data processor and is also equipped with a keypad to enter passwords and also this sistem will be equipped with Liquid Crystal Display as an interface to make it easier for users. Selenooid doorlock is used as an output of this sistem which allows it to open and lock electrically. This sistem was created with the aim of increasing security at PT Jayasegar Berkat Mandiri which makes a more effective and efficient security sistem and it is hoped that in the future this sistem can be used for other security needs
