The dissemination of personal data through digital media has increased significantly alongside the growing use of Quick Response (QR) Codes for various purposes, such as electronic tickets, certificates, and digital identities. Conventional QR Codes are open and can be easily scanned, copied, or manipulated by unauthorized parties. The personal data referred to in this study includes sensitive information such as full name, identity number (NIK/National ID), date of birth, address, phone number, and email address. This research proposes a layered security system that combines the Advanced Encryption Standard (AES) cryptographic algorithm with steganography using the Discrete Cosine Transform (DCT) method. The process begins with encrypting personal data using AES, converting the encrypted result into a QR Code, and embedding the QR Code into a digital image using DCT, hiding it in the image’s frequency domain. The digital images used are of fixed size and formats that preserve visual quality. System evaluation is carried out by testing the visual quality of the stego image, the success rate of QR Code extraction, and the integrity of the encrypted data. The results are expected to conceal sensitive information visually while maintaining its confidentiality, with potential applications in electronic ID cards, digital certificates, e-tickets, and other confidential documents.

The development of audiovisual media in the digital era provides a significant opportunity for conveying information, particularly regarding social and cultural issues. One interesting phenomenon is the acculturation of Peranakan Chinese cuisine in Indonesia, which is currently becoming less well-known among the younger generation. This study aims to represent this acculturation process through a documentary film entitled "Jejak Rasa" (Traces of Taste), using a naturalistic visual approach. The method used is a qualitative approach with field observation, interviews, and documentation strategies, integrated with a community organizing process. The research subjects included Peranakan Chinese culinary practitioners in Bandung, such as culinary business owners and museum guides. The production process consisted of three main stages: pre-production, production, and post-production. The naturalistic approach was implemented through the use of predominantly eye-level camera angles, minimal camera movement, and the use of natural lighting to produce authentic visuals. The results of the study indicate that documentary films can be an effective medium for representing cultural values, history, and culinary identity as part of the acculturation process. Thus, this work serves not only as a medium of information but also as an effort to preserve culture relevant to the development of modern media.
