Abstract

Informasi produk yang akurat dan dapat diverifikasi merupakan hak konsumen yang sering terabaikan, terutama pada produk UMKM pangan dengan masa simpan terbatas seperti yoghurt. Pelaku UMKM kerap belum memiliki mekanisme yang memadai untuk menjamin keaslian dan keterbacaan informasi kedaluwarsa pada kemasan. Vtaya Yoghurt, usaha pengolahan yoghurt di Kuningan, Jawa Barat, selama ini mengandalkan stempel tinta sebagai metode pelabelan yang hasilnya kerap pudar dan sulit terbaca. Berdasarkan kuesioner terhadap 30 responden, 86,7% menyatakan kesulitan membaca informasi kedaluwarsa dan 86,6% menyatakan perlunya mekanisme verifikasi digital. Penelitian ini bertujuan merancang dan membangun aplikasi berbasis web untuk memverifikasi tanggal kedaluwarsa dan informasi produk yoghurt Vtaya menggunakan algoritma AES-128 dan QR Code. Data kode produksi dan tanggal kedaluwarsa dienkripsi menggunakan AES-128, kemudian di-generate ke dalam QR Code yang dicetak pada kemasan. Saat konsumen memindai QR Code, sistem melakukan dekripsi untuk menampilkan informasi produk secara langsung. Sistem dikembangkan menggunakan metode Prototype dengan PHP, framework Laravel, dan MySQL. Pengujian menggunakan Black Box Testing, White Box Testing, dan User Acceptance Testing. Hasil UAT memperoleh skor 93,33% dari responden admin dan 90,91% dari 33 responden konsumen, menunjukkan bahwa aplikasi berhasil diterima dan dinilai mampu mempermudah proses verifikasi informasi produk yoghurt Vtaya oleh seluruh pengguna.

Kata Kunci: AES, Qr Code, Tanggal kedaluwarsa, Verifikasi Yoghurt

Accurate and verifiable product information is a consumer right frequently overlooked among small-scale food businesses, particularly those producing perishable products such as yoghurt. Many lack adequate mechanisms to ensure
the authenticity and legibility of expiration date information on their packaging. Vtaya Yoghurt, a yoghurt producer in Kuningan, West Java, has relied on ink stamps for labeling, a method prone to fading and illegibility. A survey of 30 respondents found that 86.7% experienced difficulty reading expiration dates and 86.6% expressed the need for a digital verification mechanism. This study aims to design and develop a web-based application to verify expiration dates and product
information of Vtaya Yoghurt using AES-128 and QR Code. Production codes and expiration dates are encrypted using AES-128 and embedded into a QR Code printed on the packaging. When consumers scan the QR Code, the system performs decryption to display product information directly. The system was developed using the Prototype method with PHP, Laravel, and MySQL. Testing was conducted through Black Box, White Box, and User Acceptance Testing. UAT results yielded 93.33% from admin respondents and 90.91% from 33 consumer respondents, confirming the application was accepted and considered effective in simplifying the verification of Vtaya Yoghurt product information.
