Combination of case-based reasoning and nearest neighbour for recommendation of volcano status

Abstract

Reasoning by relying on old data or commonly known as the Case-Based Reasoning has been implemented in many cases. Case-Based Reasoning is one method by utilizing previous cases to produce a solution. This study implements a combination of Case-Based Reasoning and Nearest Neighbor for the determination of the status of the volcano. There are 5 features that serve as a criterion for determining the status of the shallow volcanic, deep tectonic, deep volcanic, earthquake blow and previous mountain status. While the recommended status of the form of Normal, standby and alert. From the test results with 20 data as a case base and 30 test data obtained on average accuracy of the system amounted to 80,91%.
