Abstract

Bitung district was an active seismic area in North Sulawesi Province. This is because of platetectonic activity, among other things, subduction of West Molucca Sea and subduction of NorthSulawesi Trench that can cause earthquake disaster. Earthquake is an unpredictable disaster thatcan pose a danger to a region. So the purpose of the research is to minimize the impact of theearthquake disaster. The study conducted with study of the earthquake hazard analytics usingprobability approaches with 500-year-old return period, probability exceeded 10% in 50 years ofbuilding age in condition T= 0 second, T= 0.2 second and T= 0.1 second. PSHA’s calculation in theBitung region were obtained at PGA value of the same amount 1.4g – 1.8g, SA value T= 0.2 secondis 1,7g-2,1g and SA value T= 1,0 second is 0,5-0,6g. as for the turbulence of the result of teconversion of the PGA value being on the VIII-IX MMI scale which means it can cause a seriousrisk of damage to the building.

Abstract

In this study, we determined the accurate hypocenter location of November 15, 2019, the Molucca Sea earthquake aftershocks using the Modified Joint Hypocenter Determination (MJHD) method. This method calculated the hypocenter and seismic station correction simultaneously using the seismic wave travel time inversion. The P and S wave arrival time at each station from the BMKG database was used in this study. After relocated, most of the aftershocks hypocenter categorized as shallow and medium depth earthquakes with the range of focal depth between 25-150 km.

Abstract

The primary characteristics of 21st-century learning emphasize the importance of digital literacy in preparing individuals to manage information, collaborate, and adapt to rapid changes in the digital society. A project-based digital literacy learning model is crucial as it equips students with necessary skills to navigate effectively in an increasingly interconnected digital world through authentic projects integrating digital technology, enabling them to learn, innovate, collaborate, and communicate effectively in a continually evolving global context. This development study aims to produce a valid, practical, and effective "SCIENCE" Digital Literacy Learning Model based on project approaches. The research method employed is the 4D R&D model (Define, Design, Development, Dissemination). This study was conducted at SMP Advent 5 Kairagi Weru, Grade VIII, Second Semester of the Academic Year 2023/2024. Research instruments used include interviews, observations, questionnaire surveys, and achievement tests. Data analysis techniques utilized descriptive statistics. Based on the research findings, the validity test results of the project-based "SCIENCE" digital literacy learning model were categorized as valid with a percentage of 88.89%. Practicality assessment based on teacher questionnaire responses indicated a very practical category with a percentage of 91.67%, while student questionnaire analysis also indicated a very practical category with a percentage of 94.46%. The effectiveness test results were categorized as highly effective with a percentage of 88%. In conclusion, it can be inferred that the "SCIENCE" Digital Literacy Learning Model meets the criteria of being valid, practical, and effective.
