The Handling of Missing Data At Nurul Bayan Geomagnetic Station, Lombok

---

The geomagnetic data processing as required in earthquake prediction studies is
currently being interesting discussions, particularly in Lombok island. For good quality data
processing, it is very important to consider the quality of the data recorded at the geomagnetic
stations, whether they were recorded continuously in the order of time sequence or not. The time
sequence data are essential in the processing of geomagnetic data, so that data does not lose their
histories and make them as valid data. The Nurul Bayan Geomagnetic Station has been operated
since April 2018, designated for earthquake mitigation in the Lombok regions. However, the
obtained recorded data at this station have gaps or emptiness and they are not written well, so
the data do not match the time sequence (one-minutes or-seconds). In this study, 24 hours of
one-second geomagnetic data were taken from Nurul Bayan station from August to November
2018. We tackled the missing data using the interpolation method, and then we validated them
using k-means clustering. This clustering method we used to see whether the filling gaps give
an improvement in data processing. The result is the filling missing data was proved to have a
benefit to increase the accuracy in data processing using k-means clustering
