Many MSMEs in Indonesia are unable to maintain or develop their businesses due to limited business capital. These MSMEs do not have transaction records so they can not make business capital loans to the bank. The existing transaction recording applications mostly use a centralized system architecture which raises data integrity problems. A centralized system cannot ensure that the data that has been stored in the system cannot be changed, damaged, or even used by the owner of the centralized system. There are also applications that take advantage of a distributed system, namely blockchain such as Tokoin. In blockchain, data is stored in more than one storage and data that has been stored cannot be changed anymore. However, the system created by Tokoin has drawbacks, it cannot ensure that the input data by the user is valid a transaction data. The transaction recording system will be implemented with the Hyperledger Fabric, which is a permissioned blockchain and also has a smart contract in it. The system is able to meet functional needs, the system provide functionality such as data input of goods, buying goods, seeing a list of available, sold, and purchased goods. The system also fulfills non-functional requirements, such as data integrity, that is, stored data cannot be changed or damaged by unauthorized party or undesired manners.
