Abstract

Encryption and Decryption Application for QR Code using Rivest-Shamir-Adleman method and Advanced Encryption System method is an application using cryptography system, security network. Cryptography is technique-based on mathematics for dealing with information security like secrecy, integrity data and authentication data. In this system consist of plaintext, cipher key, cipher text, encryption algorithm and decryption algorithm. Plaintext is a message or data that can be read. Cipher key is input key that determine the output from encryption process. Cipher text is output from encryption process. This application using features of QR Code as an object to hide the message, using Advanced Encryption System and Rivest-Shamir-Adleman. Besides that, this application also can generate QR Code output with the plaintext inside it, then can translate the value inside QR Code with QR Encoder and processing data in QR Code to transform the plaintext into QR Code with cipher text value. Decryption process can be done until the input of the cipher key is correct so that the cipher text inside the QR Code can be restore to original. The results point that the encryption and decryption application for QR Code is fulfilling its purpose because the application can produce good results that the encrypt output is random and can be decrypt back too and also can be implemented using QR Code features.

Abstract

MSMEs in the snack food sector face dual pressures: competition with large-scale national brands on one side, and the requirement to meet modern retail standards on the other. This Community Service activity was conducted at Jiddah Krenyes, a home-industry potato chips MSME in Jakarta affiliated with the Jakarta Entrepreneur community, using a Participatory Action Research approach with four cycles: plan, act, observe, and reflect. The intervention focused on marketing transformation toward modern retail penetration through Bright Store Pertamina via six sequential phases: audit and planning, visual identity and branding optimization, digital content strategy development, Bright Store penetration through fulfillment of seven retail requirements, integrated promotion activation, and monitoring and evaluation. Reflective evaluation confirms substantive changes in the partner's business capacity: gradual fulfillment of modern retail legality requirements, consistent brand identity strengthening, more structured digital content strategy, establishment of a Bright Store pilot outlet partnership, and more effective omnichannel integration. This activity contributes to the validation of PAR integration with modern trade marketing and omnichannel strategy frameworks for Indonesian snack food MSMEs.
