Abstract

In the development of information technology that is increasingly high and increasing, as well as sophisticated times like this, tools are needed to send messages, including many media such as chat, line or the like so that we can send messages quickly and vice versa. Of all the conveniences that will certainly be very influential when we will send messages whose contents only certain people who have the right to know the contents. One that must be really vigilant and careful is a message that is confidential because if the message is spread it will have a bad impact on ourselves or others. Beberapacara can be used, one of them by securing information data by using cryptographic concepts related to information security aspects, the integrity of a data. The cryptography algorithm that will be used to solve the problem of securing information or data is by using RSA method and Blowfish algorithm method. Encryption results from the word UPI YPTK obtained results by using the RSA method that is obtained decimal results: 98 135 98 0 113 9 9 84 98 34 98 0 98 49 113 135, and the result of the encryption process using the Blowfish algorithm is Ü|*œ / 9".

Abstract

Gastroesophageal Reflux Disease (GERD) is a condition of reflux of stomach contents into the esophagus which can cause typical symptoms such as heartburn (burning in the epigastric region), acid regurgitation (bitter taste in the mouth), nausea, and dysphagia which can result in damage to the esophageal mucosa and in the long term can cause complications such as Barrett's esophagus. Based on data on patients with GERD disease in 2020-2023, there were 521 patients obtained at Bidadari Binjai General Hospital, with differences in prevalence caused by socioeconomic and lifestyle changes that can increase the incidence of GERD. The purpose of this study is to obtain the results of the combination between item-sets on the behavior patterns and lifestyles of GERD sufferers which are expected to help the agency in processing data on GERD sufferers into more effective information to determine the behavior patterns and lifestyles of GERD sufferers with the Apriori Algorithm method. From the research conducted, the results obtained rules that meet the value of 30% support and 100% confidence, if unhealthy eating patterns are often late eating, then unhealthy lifestyles are often done sleeping after eating and smoking.
