Abstract

The challenge faced by the batik industry in the industrial era 5.0 is the adaptation to technology in the production process. One way to overcome this challenge is to start from the basics in the batik industry, namely the creative process of designing batik patterns. It is important to pay special attention to this process to enhance digital transformation in the batik industry. The purpose of this paper is to present the design and creation of batik patterns using the L-System-based fractal approach. Previous research has shown that the L-System can be used to model plant growth in 2D and 3D contexts. In a similar way, the L-System is used in this study to create batik patterns. Experiments were conducted through three stages, namely Data Acquisition, Data Identification, and Modeling. The experiment results in a dataset of batik motifs that can be used as parameters to replace line segments in the L-System. The design and creation of batik patterns using the L-System only needs to be done once, so that from one pattern, a variety of different motifs can be produced easily by simply changing the parameters. This shows that the design and creation of batik patterns using L-System is more efficient and practical. In addition, the fractal dimension calculation is used to understand and describe the fractal properties of the resulting objects. In this study, it was found that there are four motifs without ornaments that have higher fractal dimension values than motifs with equivalent ornaments.

Abstract

In today's digital era, websites have become a key component of various digital services, from government and education to business. However, many security incidents occur due to undetected source code vulnerabilities, such as vulnerabilities, bugs, and code smells, which can degrade system performance and reliability. Therefore, a systematic approach is needed to detect and prevent these issues as early as possible. This study aims to implement and evaluate the effectiveness of the Static Code Analysis (SCA) method in identifying security and code quality issues in web applications. The tool used was SonarQube, which was then implemented in the SIMAK Universitas Siliwangi. Evaluation and testing were conducted on the tool's ability to detect various types of problems, its level of accuracy, and its ease of integration into the software development process. In this study, the evaluated aspects were bugs, code smells, and vulnerabilities. The results of this study found 23,241 issues, consisting of 2,356 bugs and 20,885 code smells, without any vulnerabilities found. With a problem ratio of 3.84% of the total code lines of 605,130, and a severity classification dominated by issues at the Critical and Major levels, these results provide an overview of the technical condition of the code used in SIMAK Universitas Siliwangi. This research is expected to provide practical contributions for software developers and security teams in continuously improving the quality and security of web applications. The outcomes of this study are expected to offer substantial and actionable contributions toward advancing the overall quality, robustness, and security of software systems. By strengthening these foundational aspects, the research is projected to positively influence the reliability, continuity, and long-term sustainability of academic service delivery within higher-education environments.
