In this research, we introduce the combination of two Blockchain methods. Ripple Protocol Consensus Algorithm (RPCA) and Practical Byzantine Fault Tolerance (PBFT) are applied to cryptospatial coordinates to support cultural heritage tourism. The PBFT process is still used until the preparation process to ensure a maximum error of 33%. After this process, data will be entered into the RPCA node and calculated using the equation to minimize errors with a maximum limit of 20%. After this process, the data would be sent to the commit process to store data to all connected nodes in the Blockchain network, we call this combination of two methods as R-PBFT. Combining the two methods can enhance data processing's security and speed because it still uses the PBFT work combined with the speed of RPCA. Besides, this method uses a fault tolerance value from the RPCA of 20% to enhance data processing's security and speed.
