Abstract

Traceability di pertanian modern menghadapi tantangan besar pada aspek integritas data dan risiko manipulasi, yang dapat berdampak pada kualitas serta kepercayaan konsumen. Penelitian ini berhasil merancang dan mengimplementasikan sistem traceability berbasis IoT menggunakan microcontroller, sensor suhu dan kelembapan, backend, dan algoritma SHA-256 untuk menjaga keamanan serta keaslian data lingkungan secara otomatis. Secure Hash Algorithm 256 atau yang biasa disingkat SHA-256 adalah algoritma hashing kriptografis yang dirancang untuk menciptakan sidik jari digital unik dari data input. SHA-256 menghasilkan output tetap sepanjang 256-bit. Hasil pengujian menunjukkan sistem mampu mengirim dan menyimpan data sensor dengan tingkat keberhasilan 98,98% tanpa error kritis, serta mempertahankan validitas data melalui mekanisme hash SHA-256. Pengujian validasi hash membuktikan bahwa setiap perubahan data sekecil apa pun langsung terdeteksi dan ditandai invalid secara otomatis oleh sistem. Pengujian collision pada lebih dari 5.000 data membuktikan tidak ditemukan hash ganda (collision), sehingga SHA-256 terbukti sangat aman digunakan untuk traceability lingkungan hidroponik. Dengan demikian, sistem traceability yang dikembangkan terbukti efektif meningkatkan keamanan, keaslian, serta transparansi data IoT pertanian, dan sangat potensial dijadikan acuan pengembangan smart farming di masa depan.

Traceability in modern agriculture faces significant challenges regarding data integrity and the risk of manipulation, which can affect both product quality and consumer trust. This research successfully designed and implemented an IoT-based traceability system utilizing ESP32, DHT22 sensors, a FastAPI backend, and the SHA-256 algorithm to automatically ensure the security and authenticity of environmental data. Secure Hash Algorithm 256, commonly known as SHA-256, is a cryptographic hashing algorithm designed to create a unique digital fingerprint from input data. SHA-256 produces a fixed output length of 256 bits. Testing results demonstrated that the system was able to transmit and store sensor data continously with a success rate of 98.98% and no critical errors, while maintaining data validity through the SHA-256 hash mechanism. Hash validation tests proved that any slightest change in data was immediately detected and marked as valid by the system. Collision testing on more than 5,000 data entries showed no duplicate hashes (collisions), thus confirming the high security of SHA-256 for environmental traceability in hydroponics. Therefore, the developed traceability system has proven effective in enhancing the security, authenticity, and transparency of IoT data in agriculture, and holds strong potential as a reference for the future development of smart farming.
