Abstract

The food and agro supply chain that occurs during the pandemic is the amount of supply available but is constrained by distribution due to a shortage of fleets and resource resources. Perishable agricultural products are wasted, or prices go down due to reduced quality. In this study, the smart contract design that was built was to propose a single wallet specifically for users who could find out all transaction activities carried out by inbound stakeholders, namely produc- tion, logistics, and sales in the sugar supply chain at the XY factory. The transactions in the user wallet come from the hash code when the Transaction occurred and the smart contract hash code or algorithm. Because it is a single wallet consisting of several transactions between divisions within the company, the origin of the hash only comes from the user. Meanwhile, inputting the date and volume according to the product, whether it comes from sugar cane or raw sugar, can be traced according to each process such as production, logistics, and also sales by generating a unique smart contract code in the form of a hash. Blockchain-based sugar volume traceability system records all transaction distri- bution history in an unaltered ledger through smart contract collaboration. An application design presents a transaction response mechanism in verifying the distribution of data entered using a user wallet. All data transaction distribution events are recorded and permanently stored in the Blockchain with a user wallet login. However, all nodes in the supply chain, which are under the supervision of one factory, can participate transparently and reliably.
