Abstract

One area in Indonesia that is prone to disasters is the Flores Sea area, which has the potential for earthquakes to trigger tsunamis. This is due to the location of Flores, which is in a subduction zone that originates from the collision of the Indo-Australian (South) and Eurasian plates. Inaccuracies in earthquake locations are influenced by differences in residual travel time values, mathematical solutions to location problems, and inaccuracies in the seismic velocity model used. The accuracy of determining the hypocenter of an earthquake influences the location of the earthquake source, which will later be used as a reference in appropriate earthquake disaster mitigation planning. Based on this, an analysis of earthquake hypocenter data is needed, so it is important to carry out research. This research aims to relocate the hypocenter using ObsPy with a single station. The results obtained show that the Python package, namely ObsPy, can carry out data retrieval commands through filtering, detrending, normalisation, and determining data request parameters, such as the start and end times of the desired data, location, network, and data type. This research contributes to the field of seismology because the process of determining the hypocenter requires a relatively short time. Apart from that, the accuracy obtained also provides accurate values.

Abstract

The problems faced by Islamic Religious Education Teachers in managing post-Cocid-19 learning at SD Inpres Jongaya 1 are behavior and character, such as students' lack of discipline in attending lessons, and lack of a culture of shame, namely shame if they break the rules. For example: embarrassed to come late, ashamed not to picket, ashamed not to do homework, and so on. 2). Supporting and inhibiting factors for Islamic religious education teachers in managing learning at SD Inpres Jongaya 1, namely: (a) supporting factors are, such as the school providing a Wi-Fi network, good teacher relations, and adequate school facilities. And (b) the inhibiting factor is that the teacher is not too able to know the characters of each student, the assessor that underlies the needs of students has not been conveyed in the learning process and lacks infrastructure. 3) The teacher's efforts in overcoming problems in managing post-Covid-19 learning at SD Inpres Jongaya 1, namely searching for and digging up information through training or by using search media to get updated information regarding how to manage learning and the development of the learning curriculum at SD Inpres Jongaya 1 the.
