Abstract

The rapid advancement of information technology has shifted the paradigm of tourism and culinary exploration towards mobile platforms. However, local culinary searches in Medan City are currently still conventional and random. Scattered culinary information across various social media without a comprehensive summary often confuses customers and complicates the promotion of micro-culinary businesses (UMKM) in the digital era. Existing commercial platforms often burden local sellers with high platform taxes. This research aims to design and implement an Android-Based Mobile Application for Local Culinary Recommendations as an effective solution to these problems. This application is built natively using the Java programming language for the Android client side, integrated with a PHP Application Programming Interface (API) and MySQL relational database. The system design involves a Client-Server architecture and includes three distinct access rights: User, Culinary Admin, and Super Admin. Implemented features include dining place search, interactive reviews, ratings, popularity levels based on view counts, and Google Maps API integration for precise culinary navigation routes. The result of this research is a self-managed mobile application that accelerates navigation access for users while assisting business owners in managing their stalls independently, objectively, and expanding their promotional reach without internal transaction fees.

Abstract

The rapid development of cloud storage services within cloud computing technology offers significant convenience for storing and managing digital data. However, this development also raises serious data security challenges, including risks of data leakage, theft, and unauthorized access. One widely used solution to address these issues is the implementation of cryptographic techniques, particularly the Advanced Encryption Standard (AES) algorithm with a 256-bit key length. This study aims to analyze the implementation of the AES 256-bit algorithm in enhancing data security in cloud storage services through a literature review approach. The study reviews ten relevant national and international journal articles discussing the application of AES-256 in digital storage systems and cloud computing environments. The results indicate that the AES 256-bit algorithm is effective in maintaining data confidentiality and integrity during both storage and transmission. The 256-bit key length provides a high level of security and strong resistance to cryptanalytic attacks. However, several studies also identify challenges related to processing time efficiency and encryption key management. Therefore, it can be concluded that AES 256-bit is a reliable solution for improving data security in cloud storage services, provided that its implementation is adapted to system requirements and supported by effective key management.

Abstract

Digital image security is an important issue in this era of increasingly massive multimedia-based data exchange, especially for sensitive information that requires a high level of protection. This study aims to analyze the performance of the Rivest Shamir Adleman (RSA) asymmetric cryptography algorithm in the digital image encryption process based on the Mean Squared Error (MSE) and Peak Signal-to-Noise Ratio (PSNR) parameters, as well as encryption and decryption times. The method used is a quantitative experiment on 30 digital images with varying resolutions (256×256, 512×512, and 1024×1024 pixels) and two RSA key lengths (1024-bit and 2048-bit). The test results show that the MSE value ranges from 0.001068 to 0.002620 and the PSNR value ranges from 75.08 to 78.34 dB, indicating that the decrypted images are of very high quality and close to the original images. However, the computation time increased significantly with increasing resolution and key length, with RSA 2048-bit taking almost twice as long as RSA 1024-bit. These findings show that the RSA algorithm is very effective in maintaining the integrity of digital images, but has limitations in terms of computational time efficiency, especially for high-resolution images. Therefore, a balance between security and performance is needed in practical implementation.
