Integrating CodeBERT for Enhancing Security in the CI/CD Pipeline During Cloud Application Deployment
No full textThe digital transformation and widespread adoption of cloud computing have driven
the use of Continuous Integration/Continuous Deployment (CI/CD) methods in modern
application development. However, conventional CI/CD practices often lack
comprehensive security testing, focusing primarily on functional validation. This study
proposes the integration of the CodeBERT artificial intelligence model into the CI/CD
pipeline to enhance application security before cloud deployment. CodeBERT is utilized
to automatically detect code vulnerabilities, including severity levels and vulnerability
types, through a multi-task learning approach. A CVE-based dataset is used to fine-tune
the model. The system is implemented using GitHub Actions and Firebase for
development and deployment. Test results show that CodeBERT achieves an accuracy
of 80.6% for severity classification and 76.0% for vulnerability type classification. This
research demonstrates that AI integration—such as CodeBERT—into the CI/CD
pipeline can proactively and efficiently strengthen security in cloud-based DevOps
workflows.100 PagesSkripsi Sarjan
Synthetic Chitosan Microcapsules-Purple Leaf Extract (Graptophyllum Pictum L. Griff) With Ionic Gelation Method And Its Characteristics
No full textBackground: Indonesia boasts a rich biodiversity, including a variety of plants that produce secondary metabolites. These compounds play a crucial role in plant maintenance and adaptation mechanisms and are widely used in traditional medicine. One such plant is the purple leaf (Graptophyllum pictum L. Griff). Purple leaf is a plant commonly used as a traditional medicine. It is often found growing wild in rural areas or planted as a hedge or ornamental plant. Purple leaf possesses various pharmacological activities, including antioxidant, anti-inflammatory, anti-diabetic, analgesic, photoprotective, immunomodulatory, nephroprotective, anti-hemorrhoidal, and antibacterial properties. These pharmacological activities stem from the presence of active compounds such as flavonoids, tannins, steroids, alkaloids, polyphenols, and saponins. However, these compounds are sensitive to environmental conditions such as light, temperature, air, and salinity.
Purpose: Therefore, a method is needed to maintain the stability of these compounds by microencapsulation with the ionic gelation method.
Method: The method used in this study is the manufacture of microcapsules with the ionic gelation method. The gelation method is carried out by mixing purple leaf extract with a natural polymer in the form of chitosan. To find out whether the ionic gelation method is suitable for microencapsulation, morphology and particle size tests were carried out and the total phenol content and efficiency percentage were also calculated.
Results: The results of the characterization of purple leaf microcapsules using the ionic gelation method were with the highest total phenol content of 0.125, the highest efficiency percentage was 26.93%, the shape was in the form of microcapsules and the average particle size obtained was 0.65159 m.
Conclusion: The ionic gelation method is effective in maintaining compound stability because it does not require high temperatures in the processing process.
Keywords: Purple Leaf, Ionic Gelation, Microcapsules, SEM Test, Particle Size60 PagesKertas Karya Diplom

The purpose of this study was to determine and analyze how much influence food price perceptions have on food purchasing decisions directly or indirectly through purchasing power, price considerations, and product quality on consumers in Binjai City. This research uses quantitative methods with accidental sampling techniques and the number of respondents is 100 people. The data analysis method used is path analysis with the help of SPSS 30.
The results showed that directly, the perception of food prices had a significant effect on food purchasing decisions with a magnitude of 30.2%. Indirectly, the effect of perceived food prices on food purchasing decisions through purchasing power is 9.24%, through price comparison is 7.62%, and through product quality is 11.37%. From the Sobel test results, the indirectly significant path is only through purchasing power, while through price consideration and product quality is not significant. This shows that despite price increases, consumers continue to purchase food because food is a basic need that is inelastic. However, consumer purchasing power remains an important factor mediating purchasing decisions.109 PagesSkripsi Sarjan
