Abstract

Authentication security is a crucial aspect of web application development, particularly in login systems that function as the primary gateway to an application or web service. The authentication process plays a vital role in ensuring that only authorized users can access the system, thereby preventing data breaches, information misuse, and potential system damage. Traditional login methods that store passwords in plain text or rely solely on session IDs are vulnerable to theft and session hijacking. This research proposes the implementation of JSON Web Tokens(JWT) with Base64 encoding, integrated through Web Service technology, to enhance login system security. JWT is a JSON-based token standard used for secure information exchange between clients and servers. The token consists of three parts—header, payload, signature—each encoded using Base64URL. Base64 is an encoding method that converts binary data into ASCII text, making it safe for transmission over HTTP protocols. In this implementation, the bcrypt algorithm is utilized for password hashing, ensuring that the original password is never stored directly in the database. The Web Service acts as an intermediary for communication between the client and server without the need to store session data on the server. During login, the system verifies credentials, generates a JWT token, and sends it to the client for subsequent authenticated requests. Testing results demonstrate improved security, as tokens can be verified without maintaining server-side sessions, while Base64 encoding ensures safe data transmission. This implementation is expected to serve as a practical solution and reference for future advancements in web application security.

Abstract

The traditional New Student Admissions (PPDB) procedure is frequently plagued by major issues, such as administrative responsibilities, data entry mistakes, and a lack of actual real-time public transparency (Rosmiati, 2020). By concentrating on the design and implementation of a responsive, web-based PPDB information system, this study seeks to resolve these challenges. The underlying technological solution involves using the Bootstrap framework (Susanto & Permata, 2020) to guarantee that the system's interface is strong, user-friendly, and performs at its best across all platforms. a range of user gadgets (Wijaya & Hadi, 2023). The system is developed using the Waterfall methodology, which includes a thorough needs analysis, system design, implementation using PHP and MySQL, and extensive testing (Setiawan & Cahyono, 2020). According to the research, the integrated system was successful in optimizing the registration process, which is a critical component of increasing administrative efficiency (Purnomo & Wibowo, 2024). Additionally, the use of Bootstrap resulted in a uniform and contemporary user interface, which greatly enhanced the experience for potential students (Pratama et al. , 2022). In conclusion, the web-based PPDB system that has been developed and is supported by the responsive capabilities of the Bootstrap framework provides a practical, open, and scalable solution for today's needs. instructional establishments. The integration of a document verification component utilizing machine learning should be the subject of future research.

Abstract

This study aims to analyze the influence of social media and marketplaces on consumers' purchase intention toward online football shoes products in Indonesia. The research employed a quantitative approach with a causal descriptive design. The sampling technique used was purposive sampling, resulting in 102 respondents who had searched for or purchased football shoes through social media and marketplace platforms. Data were collected through a Google Form questionnaire and analyzed using multiple linear regression with SPSS version 25. The validity test showed that all 24 questionnaire items had correlation coefficients higher than the critical value (r > 0.361), while the reliability test indicated Cronbach’s Alpha values above 0.70, confirming that the instrument was valid and reliable. The regression equation obtained was Y = 4.614 – 0.045X₁ – 0.096X₂, with a coefficient of determination (R²) of 0.010. The partial t-test results revealed that social media (Sig. = 0.666) and marketplace (Sig. = 0.347) had no significant effect on purchase intention. Likewise, the simultaneous F-test showed that both variables did not significantly affect purchase intention (F = 0.507; Sig. = 0.604). Nevertheless, descriptive analysis indicated high mean scores for social media (4.015), marketplace (3.983), and purchase intention (4.051), suggesting that respondents held highly positive perceptions of digital marketing for football shoes products. The insignificant inferential results were likely influenced by data homogeneity and a ceiling effect, which limited the variability of respondents’ answers.

Abstract

Offshore gas production piping systems operate under high-pressure and elevated-temperature conditions, requiring accurate stress analysis to verify code compliance and ensure reliable structural performance. This study investigates the stress behavior of a piping system connecting a production well to a test manifold using analytical calculations and CAESAR II simulations in accordance with ASME B31.3. Engineering data, including piping geometry, material specifications, operating conditions, and support configurations, were obtained from project design documents. Sustained and thermal expansion stresses were first estimated using simplified analytical calculations and subsequently verified using CAESAR II simulations. The maximum sustained stress occurred at Node 9100, with analytical and numerical values of 124.00 MPa and 96.70 MPa, respectively, corresponding to a deviation of 28.24%. For the thermal expansion load case, the maximum stress was observed at Node 9320, yielding analytical and numerical values of 2.89 MPa and 2.44 MPa, respectively, with a deviation of 18.45%. These deviations are primarily attributed to the simplified assumptions adopted in the analytical calculations, differences in boundary condition representation, and the more detailed three-dimensional pipe flexibility modeling incorporated in CAESAR II. All calculated stresses remained below the allowable stress limits specified by ASME B31.3 (177.20 MPa for sustained loading and 206.84 MPa for thermal expansion loading). Therefore, the investigated piping system satisfies the code allowable stress requirements under the evaluated sustained and thermal expansion loading conditions. The findings demonstrate that simplified analytical calculations can provide a practical independent engineering verification of numerical simulations during preliminary piping design, while CAESAR II remains essential for comprehensive code-compliance evaluation.
