Abstract

The employee data management at PT Bersih Sukses Sejahtera is still carried out using Microsoft Excel in spreadsheet form, which has the potential to cause recording errors, data duplication, delays in information retrieval, and increase the risk of employee data leakage and loss. This study aims to design an integrated web-based employee information system by implementing the Advanced Encryption Standard (AES)-256 security algorithm to improve data management security. The method used is Waterfall which includes the stages of planning, requirement analysis, design, implementation, testing, deployment, and maintenance. Data collection techniques are carried out through observation, interviews, and literature studies, while the research data includes employee data, positions, departments, training, and educational history. The system was developed using the PHP programming language and MySQL database. The results of the study show that the system is able to integrate employee data management in one platform, while the implementation of the AES-256 algorithm successfully secures URL parameters in the employee data module through encryption and decryption processes. Testing using the Black Box Testing method on 15 features obtained a 100% success rate, so that all system functions run according to user needs. Thus, the developed system is able to support structured personnel data management while increasing information security and confidentiality through the application of the AES-256 algorithm.

Abstract

The development of information technology encourages companies to implement digital systems to support administrative management, including employee attendance processes. PT Mitra Perkasa Ekatama still uses fingerprint machines that have limitations in monitoring the attendance of employees who work outside the office or project locations and do not yet support attendance location validation. This study aims to design a web-based employee attendance system by implementing the Haversine Algorithm as a method for calculating the distance between the user's location and the company's location to validate attendance. The system development method used is Waterfall which includes the stages of planning, needs analysis, design, implementation, testing, implementation, and system maintenance. The system was built using PHP, HTML, CSS, JavaScript, MySQL, and utilizes Global Positioning System (GPS) technology. The Haversine Algorithm is used to calculate the distance based on latitude and longitude coordinates so that the system can determine whether the user is within the permitted attendance radius. The results of the study show that the system successfully integrates login features, employee data management, positions, departments, attendance entry, attendance departure, permit applications, leave applications, and attendance recapitulation in one web-based application. Testing using the Black Box Testing method shows that all system functions run well with a success rate of 100%. The resulting system is able to help companies in automatically validating attendance locations and improving the management of employee attendance data in an integrated manner
