Abstract

Data security is an important priority, as it relates to privacy, integrity, authentication, confidentiality, and customer and sales data. The confidentiality and security of customer and sales data is the most important thing in conducting business in the industrial 4.0 era, which is now all-digital. Therefore, the research objective in this paper is to secure customer data using the RSA (Rivest Shamir Adleman) cryptographic algorithm implementation. The strength and security of the RSA algorithm lie in the level of difficulty in factoring numbers into prime factors. The research in this paper uses customer data and car sales at PT. Sutan Indo Various Cars Pematangsiantar. Based on these data, a decryption encryption application will be built using the RSA algorithm. This RSA cryptographic algorithm uses a key length of 1024 bits and plaintext in the form of files with the extension Microsoft Office. The first step is to convert the plaintext and the key into hexadecimal form. The results showed that the length of the file used would affect the encryption and decryption process time. The longer the file size, the longer it will take for the encryption and decryption process. So it can be concluded that the RSA algorithm is effectively used to secure data that is not too large in file size.

Abstract

A baby swing is one of the objects commonly used by mothers to help put their babies to sleep. Starting from mothers who live in big cities to remote villages, they are familiar with baby swings. Usually, babies fall asleep quickly when sleeping in a swing. Another reason is that the baby can sleep longer, so the mother can do other unfinished activities. This research aims to design the design of an automatic baby swing system using the Arduino Uno R3 microcontroller Atmega 328. The assembly process of this tool uses a combination of the Arduino Uno R3 microcontroller with sound sensors, servo motors, led lights, and several supporting components such as jumper cables, boards, and others. Based on the experimental results, this tool can be used as a control system for the baby's swing, so that the swing will automatically move on its own when the baby cries, so that the baby can fall back asleep. So it can be concluded that with this automatic baby swing, it will help ease the work of a mother who wants to do other work.
