Abstract

Data is an essential asset that must be protected due to its strategic role in maintaining the continuity of information systems. Therefore, data security becomes a crucial aspect in information management. One of the approaches to ensure data security is through the application of cryptographic techniques. Two commonly used classical cryptographic algorithms are the Rail Fence Cipher and the Vigenere Cipher. However, the use of a single algorithm has weaknesses, as it remains vulnerable to brute-force attacks. This study aims to combine two cryptographic methods, namely the transposition technique (Rail Fence) and the substitution technique (Vigenere), to enhance resistance against brute force attacks. The research employs an experimental method by implementing the combined algorithms using the Python programming language. Testing was conducted on three scenarios: encryption using Rail Fence, Vigenere, and their combination. The results show that the combined algorithm increases key space and produces more complex character distribution patterns, thereby improving security against brute-force attacks.

Abstract

Due to its manual reliance on conventional promotional techniques such as distributing flyers and posters, PT Lestari Inti Properti faces challenges in selling subsidized housing products. In the digital era, this situation limits promotional reach and reduces marketing effectiveness. The goal of this project is to create a web-based marketing information system that can manage the company's sales and administration data in an integrated manner and function as a digital promotional tool. Using the Unified Modeling Language (UML) methodology, prototyping techniques are applied through the phases of rapid design, testing and feedback, prototyping, and requirements communication. The result of this study is the design of a prototype housing marketing information system that includes a login module, housing data management, ordering procedures, and transaction reports. Use case structures, activity diagrams, and class diagrams are used in the design of this system to fully explain how users interact with business operations. This system can increase marketing reach, speed up administrative procedures, and reduce data input errors, according to the design results. Therefore, PT Lestari Inti Properti can improve operational effectiveness and competitiveness in the digital market by using a web-based marketing information system.

Abstract

The web-based promotion and ordering information system is designed to facilitate users in ordering photography packages online. This website makes it easy for users to find information about Demahouse Studio and conduct promotions, simply through the website. This system also simplifies data management for administrators, including package data, order data, gallery data, and transaction data. Prior to this website, Demahouse Studio still used manual ordering and data management, resulting in no valid order data storage. Users seeking photography services had to book directly with the studio. By utilizing information technology, the website is expected to simplify user access and compete with other studios. To facilitate this, attractive and up-to-date promotional media and information are also needed on the website.

Abstract

This research focuses on developing a web-based office information system for Dwigital.id (CV. Klik Anugerah Ciptareka) using the CodeIgniter framework to enhance internal work efficiency and accelerate customer interaction through WhatsApp API integration. The research employs a qualitative approach with the Waterfall development model, consisting of stages such as requirements analysis, system design, implementation, testing, and maintenance. The system includes main features such as CRUD Withdraw, CRUD Sales System, and Monitoring System integrated with WhatsApp for direct communication with customers. The testing process uses the Black Box Testing method to evaluate the functionality an reliability of each module. The results show that the system runs effectively and meets user needs, improving administrative performance and real-time customer engagement. The developed system is declared feasible for operational implementation and contributes to improving Dwigital.id digital service management.

Abstract

The quality of public service is a crucial factor for companies such as the Regional Water Company. The main challenges often faced are the slow handling of customer complaints, difficulty in accessing billing information, and the bureaucratic process of new connection registration. This research aims to design and build an integrated web and mobile-based customer service information system. The research method used is the Waterfall model, which includes the stages of requirements analysis, system design, implementation, and testing. The result of this research is the customer service application, which consists of three platforms: (1) A back office web for administrators, supervisors, and superadmins to manage master data, monitor, and delegate complaints and reports; (2) An Android Mobile Application for Customers, featuring online complaints, complaint tracking, new connection registration, bill checking, self-service meter reading, and news information; (3) An Android Mobile Application for Field Officers, which functions to receive and update the status of complaint work orders. The implementation of this system has successfully transformed manual business processes into digital ones, thereby increasing response speed, data transparency, and customer satisfaction one of them is PERUMDA Air Minum Tirta Mayang.
