| Summary: | One of the efforts to implement good and clean governance is through
transparency and accountability, among others, through the application of the
electronic official documents which aims to improve work effectiveness and
productivity as well as orderly administration within government agencies. In
general, the electronic official documents system is designed with a centralized
system and managed by each government agency, so that data and records of
official documents process activities are stored in a centralized database and
managed by an organizational unit. However, there are some disadvantages of
this centralized system, especially in the workflow of official documents that
involve more than one organizational unit. i.e. dependence on third parties which
is the sole authority of the official documents data management. If there is a
system failure there is a certain period of time, it will increase the activity cycle
time and decrease activity time efficiency in the official documents business
process.
The blockchain-based solution described in this research is to avoid the
occurrence of delay times during the activity cycle time in business processes
when a system failure occurs which can cause a decrease in activity time
efficiency. Blockchain makes the official documents system become “Trusless
Operation” with each participant of different organizational unit having a copy of
transaction data through a consensus mechanism. In this study, the stages of
designing a blockchain-based data storage system are explained starting from the
general architectural design. In addition, the smart contracts algorithm is
designed according to the business logic of the official documents, and the
implementation of Byzantine Fault Tolerance (BFT) based consensus mechanism.
The simulation results show that our system can reduce time delay in activity
cycle time during a system failure as long as the number of faulty peers within the
tolerance limit so that it can increase the activity time efficiency.
