Abstract

Corn farming on the island of Java plays a crucial role in meeting the nation's food needs. However, variations in land conditions across provinces in Java result in differing production levels. This disparity affects the supply of corn in the market, and the selling price often does not align with farmers' expectations. Therefore, this article aims to determine the optimal timing for distributing corn, particularly on the island of Java, using the Euclidean algorithm. The Euclidean algorithm is used to calculate the greatest common divisor (gcd), which in turn is applied to determine the least common multiple (lcm). The lcm results can serve as a reference for identifying the best time to sell corn to prevent price declines. Additionally, a comparison of production levels across provinces is presented to help corn farmers understand when and where to distribute their produce to achieve maximum profit.

Abstract

This article combines a simple cryptographic algorithm, Caesar Cipher, with a more complex algorithm, RSA, in order to increase the security of encrypted text messages. Text messages are first encrypted with the Caesar Cipher algorithm, which is then re-encrypted using the RSA algorithm. By utilizing number theory, specifically about integers and modulo arithmetic in the RSA algorithm, a public key and a secret key are obtained that will increase the security of the encryption process in this article. Due to the increased security of the text message, uninvolved parties cannot read the actual text message.
