Abstract

Operating systems for mobile devices are growing. Android is a mobile operating system that is now very popular and widely used by people. For the purposes of the security aspect, Android has also provided specifically for cryptographic functions, such as encryption, decryption, and so on. Insecure message delivery can occur because when sending, the message sent is in the form of an original message so that if a message is taken from the delivery line, the message will be known by unauthorized parties. So we need a security on a message data. Encryption and decryption can be used to make messages so that they cannot be read or understood by other people who do not have access rights. The technique of securing data and information is known as cryptography. The use of the Triple Transposition Vigenere Cipher (TTVC) algorithm has been carried out on SMS security (Short Message Service) in order to maintain the integrity and security of the message content and cover gaps in SMS security. The message sent will be encrypted using the Triple Transposition Vigenere Cipher first so that the contents of the message can be read by the sender and recipient. Based on what has been discussed above the author will design a Text Message Security Application Using a Combination Algorithm of Triple Transposition Vigenere Cipher and One Time Pad Based on Android Studio to provide security for messages from unauthorized parties.

Abstract

Posyandu services as part of community -based health efforts still face challenges in data management in posyandu activities that are mostly carried out manually, such as recording toddler data, immunization schedules, and monthly reports that result in data irregularities, information duplication, and delays in services. This has an impact on time efficiency, accuracy of recording, and difficulties in reporting and monitoring children's growth and development. This study aims to develop a web -based health monitoring monitoring system and growth and development of children at the Medan Johor Puskesmas UPT. The importance of this research is based on the need for information systems that are efficient, accurate, and can be accessed in real-time by Posyandu cadres, heads of puskesmas, and parents of toddlers. The main objective of this study is to design and implement a web -based system that can help the registration process, growth and development, as well as digital recording of immunization. This study uses the Rapid Application Development system development method because it is fast, iterative, and greatly involves users in the development process. The results of this study indicate that the system that was built can increase cadre working time efficiency, reduce the risk of data loss, and facilitate access to information for parents.

Abstract

The tourism sector has become a vital component of the economy, contributing significantly to the income of both regions and countries. In South Nias Regency, there are various unique tourism assets, such as the traditional Lompat Batu (Stone Jumping) ritual, distinctive traditional house architecture, colorful traditional costumes, and a series of breathtaking beaches that attract a large number of visitors. The region's strategic geographical location further enhances the potential for developing its tourism sector. However, despite the rich cultural and natural assets, the tourism sector in South Nias Regency faces challenges such as limited access to comprehensive and up-to-date information about tourist destinations. The need for an improved information system has become more urgent, as the current tourism data is fragmented, not fully integrated, and lacks interactive features. This makes it difficult for potential travelers to access accurate and reliable information regarding the region's attractions, accommodations, and travel tips. Therefore, this study proposes the development of a web-based Tourism Information System that utilizes a User-Centered Design (UCD) approach. The UCD methodology ensures that the system is developed with the end user in mind, focusing on user needs, ease of use, and efficient interaction at every phase of the design process. The proposed system aims to be responsive and user-friendly, providing travelers with a convenient platform to access accurate and geographically relevant tourism data. Through the system, users can easily explore various tourist spots, rate destinations, and read user reviews, which will improve their overall travel experience. The system also features an interactive map that allows visitors to visually locate attractions, accommodations, and other points of interest.
