DATA SECURITY SCHEME WITH A COMBINATION OF ADVANCED ENCRYPTION STANDARD (AES) AND RIVEST SHAMIR ALDEMAN (RSA) ALGORITHMS

2024-11-15T09:15:15+07:00

The rapid development of data drives the need for security in the data transmission process, with the aim of preventing access by unwanted parties to view the contents of the data sent. In order to achieve an optimal level of security, one of the strategies used is the application of cryptography. Cryptography using the Advanced Encryption Standard (AES) and Rivest Shamir Adleman (RSA) algorithms separately has often been used to protect the security of messages, whether in the form of text or digital images. This research will utilize a combination of the AES and RSA algorithms. This merger aims to ensure that the RSA algorithm can play a role in encrypting secret keys, while the AES algorithm is used to secure the original text (plaintext). The sender will receive the private key, encrypted secret key, and ciphertext. The recipient decrypts the secret key first using the RSA algorithm, and after obtaining the secret key, decrypts the ciphertext using the AES algorithm along with the previously decrypted secret key. It is hoped that this research will provide better security for sending information because the process of reading the contents of a secret message must go through both combination algorithms.

DESIGNING UI/UX DESIGN OF MOBILE APPLICATION AT SOLARIA RESTAURANT USING LEAN UX METHOD

2024-11-15T09:13:55+07:00

The rapid development of information technology encourages companies in various sectors to adopt mobile applications to improve customer experience and operational efficiency. Solaria, a leading fast food restaurant in Indonesia, needed to design an optimal user interface (UI) and user experience (UX) for its mobile application. This research aims to design the UI/UX of the Solaria app using the Lean UX method. The research method involves several stages: customer interviews and questionnaires to understand user needs, wireframes and initial prototypes, testing and iteration based on user feedback, and final evaluation of the refined prototype. The result of this research is a relevant and user-friendly design. This research is expected to serve as a reference for mobile application developers to be able to make a full application.

APPLICATION OF DIJKSTRA'S ALGORITHM IN DETERMINING THE SHORTEST ROUTE TO MRICAN LANDFILL

2024-11-15T09:30:18+07:00

This research explores the implementation of Dijkstra's Algorithm to determine the shortest route in waste management, particularly from Temporary Disposal Sites (TPS) to the Mrican Final Processing Site (TPA). With advancements in information technology, determining an efficient waste collection route is crucial for reducing operational costs, travel time, and fuel consumption. This study utilizes historical data and current road conditions to simulate routes, addressing challenges such as traffic congestion and unpredictable road conditions. Dijkstra's Algorithm has been proven effective in previous studies in transportation and logistics contexts, and is thus adopted in this study. The results show that applying this algorithm can enhance waste transportation efficiency, providing practical solutions for TPA Mrican management to optimize collection routes, reduce operational costs, and improve collection time efficiency.

SENTIMENT ANALYSIS ABOUT UNHAN RI THROUGH TWITTER SOCIAL MEDIA

2024-11-15T14:02:54+07:00

This study aims to determine public opinion regarding Universitas Pertahanan Republik Indonesia (UNHAN RI). As a new university, responses regarding public opinion need to be carried out so that the university can provide better services and educational programs. To see the public response to UNHAN RI, a Machine Learning method is used, namely Naïve Bayes. This Naïve Bayes modeling can help to classify public sentiment analysis towards UNHAN RI. By Naïve Bayes modeling, an accuracy value of 60.78% was obtained with three classification results, namely positive, negative, and neutral. The largest classification results were obtained in the positive class of 60.8%, the neutral class of 33.3%, and the negative class of 5.9%..

APPLICATION OF THE LARAVEL FRAMEWORK IN THE DEVELOPMENT OF A WEB-BASED INFORMATION SYSTEM FOR BIOPHYSIO PHYSIOTHERAPY CLINIC

2024-11-21T16:31:44+07:00

Healthcare services particularly in the field of physiotherapy, play a crucial role in the recovery of patients with movement and functional impairments. The Biophysio Physiotherapy Clinic faces challenges in managing patient data, scheduling therapy sessions, and tracking patient progress as the number of patients increases. To address these issues, this study developed a web-based information system using the Laravel Framework, known for its flexibility. The Rapid Application Development (RAD) method was employed in the development of this system, involving iterative user feedback. The testing results demonstrate excellent system performance in terms of speed and responsiveness, with a 95% score on Google PageSpeed Insights, and effective handling of workload as evidenced by load testing results. In the load testing, the average response time for login requests was 6483 ms, while for admin requests, it was 1803 ms. The throughput reached 0.06 requests per second for login requests and 1.42 requests per second for admin requests. With stable response times and no errors during testing, this system is ready for implementation and is expected to improve the operational efficiency of the clinic while providing a better user experience. The Biophysio Physiotherapy Clinic's Web-Based Information System successfully passed both performance testing and load testing

ANALYSIS OF USER ACCEPTANCE TESTING ON A SHIPPING APPLICATION TO DETERMINE THE QUALITY OF THE SYSTEM

2024-11-21T16:47:14+07:00

An application is a type of software or program that runs on a system. It can be either a computer or mobile device[1]. Applications should be tested all the way to the end user in order to have a clear understanding of the actual user and their experience with a product through feedback from customers who have had first hand experience with the product[2]. Also, it is necessary to include user acceptance testing as it brings end users of the system to test functions within the system as to whether there is proper working of the features and if the user’s needs are catered for[3]. Therefore, the aim of this study is to evaluate the testing of the developed goods delivery system application among its end users with special focus on user acceptance testing. User acceptance testing is applied in this case using open beta testing. The searching aim is to test the interface of the goods delivery system application using user acceptance testing and later establish the accuracy of the testing of the system application. The data collection method was performed using interviews, observations, literature study and documentation which enabled effective data collection. The research was done through questionnaires which were sent to the end users with a sample size of 50 respondents. The dissemination of questionnaires is necessary as the first task of any testing activity using the User Acceptance Testing. The research on application testing processes using the User Acceptance Testing method and its aspects achieved a per cent accuracy level of 85% and testing decision resultant as “Agree” of 213.5.
