Abstract
In recent times, the supply chain has developed into a large ecosystem. Various products moving from party to party require cooperation between stakeholders in managing the data generated. The problem is that every company has its own transaction records that can be inconsistent and their storage is centralized and not integrated between companies. This makes transaction records easy to falsify. Efficient data management is needed from the producer to the store so that consumers can trust the product. Therefore, the authors designed a product tracking system using blockchain by implementing proof of work (PoW) as the consensus algorithm, SHA-3 256 as data security, Mongo database as cloud-based data storage and QR Code as the output. As a result, transaction data from producers, distributors to retail stores are stored completely in MongoDB which is a cloud-based database, then the resulting QR Code can be used to view details of producers, distributors to retail stores that sell them. The simulation and trial results show the product tracing system design is successful as expected.

Summary
Rantai pasokan saat ini berkembang menjadi ekosistem yang besar[1]. Berbagai produk yang bergerak dari satu pihak ke pihak lain yang membutuhkan kerja sama antar pemangku kepentingan dalam mengelola data yang dihasilkan. Teknologi blockchain memberikan potensi yang sangat blockchain untuk melaksanakan sertifikasi dari produk baik dalam mengatasi isu tersebut karena adanya fitur ini dengan penelusuran keseluruhan rantai pasokan dari seperti kekebalan, transparansi dan desentralisasi. Berbagai pendekatan dimasukan dalam aturan dalam penelitian ini dalam membangun implementasi penggabungan dari IoT berbasis blockchain untuk teknologi blockchain pada rantai pasokan penelusuran mendapatkan solusi dan tingkat penyebaran dari produk komputer dengan menggunakan konsensus blockchain untuk memvalidasi identitas individu dan proof of work dan hashing SHA-3 256 dimana data dari aset [1]. Berdasarkan permasalahan tersebut, dibuatlah suatu sistem yang dapat digunakan untuk menyimpan catatan transaksi terdesentralisasi dengan memasukan detail produk saat produk berada di produsen, distributor dan retailer dimana penggambarannya dapat dilihat pada Gambar 1
