Abstract

This study aims to find out the feasibility of developing physics comic media on Newton's Law material so that it can be applied to the learning process. The research was conducted at St. Gabriel Maumere Catholic High School Class X MIA which totaled 22 students. According to the findings of the observations, it appears that learning in class still uses teaching materials in the form of books and various facilities such as projectors, LCDs, so most students feel less attractive in the interest in learning. This is due to the fact that educators are less developing learning media, this is a limitation of knowledge. In order to generate a certain product and evaluate its efficacy, a research approach known as research and development (R & D) or research and knowledge (if translated into Indonesian) is employed. Based on the findings of the data analysis, the product was validated by two experts, namely media and material specialists, and received scores of 80% and 91.1% in the 'Very Good' category. Furthermore, the product was tested to 22 students by obtaining 87% results included under the "Very Good" heading. Thus, it can be said that creating Fiska comics based on information about Newton's Law is thought to be doable and applicable in the upcoming educational process.

Abstract

A method that does not require a main earthquake (master event) that can be used simultaneously to relocate a very large number of earthquakes with wide hypocenter separation is called the double-difference method. A method used to relocate the aftershocks in Seririt Singaraja on November 14 2019 with coordinate positions 113.478 – 115.181 East Longitude and 8.357 – 7.894 South Latitude. The earthquake data used in this research was accumulated from 85 BMKG seismic stations. Data analysis uses cross-correlation time differences which can increase the accuracy of travel time between the receiving station and the earthquake, thereby reducing errors in calculations. The double difference method used to relocate the earthquake in the Seririt Singaraja area showed that there was a shift in the location of the earthquake hypocenter before and after it was relocated. Horizontally and vertically, the distribution of earthquake hypocenters before and after being relocated occurs when there is a collection of location shifts. The results of this research were able to relocate 152 aftershocks properly. The main earthquake after being relocated was at a depth of 17 km, while the distribution of aftershocks was at a depth of around 6-25 km, so that it can more accurately describe the position of the earthquake source and is able to show clearer and easier to interpret structural patterns.
