Abstract

Based on the BMKG report on Wednesday, July 29, 2018, at 05.47 WIB, an earthquake with a magnitude of 6.4 SR occurred at the epicenter at a depth of 24 km and was 47 km northeast of the island of Lombok. They are allegedly originating from the Back Arc Thrust Flores, the interaction between the Indo-Australian Plate and the Eurasian plate. This study aims to analyze the subsurface structure of the island of Sumbawa and Flores sea based on the distribution of density values. The analysis was carried out by modeling the subsurface structure based on regional gravity field anomaly data. The data used is secondary data downloaded from the topex.ucsd.edu page 18,400 measuring points. Data processing consists of data correction, separation of anomalies, determination of the Second Vertical Derivative (SVD) value, and 3D and 2D inversion modeling. The data corrections performed are Bouguer correction and terrain correction to produce the total gravity anomaly value. Upward continuation is used to separate regional anomalies and residual anomalies. Analysis of the Second Vertical Derivative (SVD) value was carried out to identify rock contact positions and fault structures. The 3D inversion modeling is done by making a mesh model, and to get a 2D cross-section, six slices are used in the 3D model. The results of the 3D model and 2D cross-section, namely the island of Sumbawa to the Back Arc Thrust zone of Flores, consists of 3 main layers comprised of the upper crust with a density of 2.29 gr/cc - 2.63 gr/cc, the middle crust with a density of 2.64 gr/cc - 2.90 gr/cc, and the lower crust with a density of 2.91 gr/cc - 3.14 gr/cc, and based on the model and SVD value, it shows that the Flores back fault, the reverse fault type, starts at a depth of ± 26 km

Abstract

This study aims to improve students' social skills through a collaborative learning model in Basic Biology courses. This is a research and development (R&D) study. This research consists of six stages, namely: (1) a preliminary study which is evaluative and explorative in nature toward the previous learning model, (2) designing a conceptual model, (3) validating the model, (4) testing the conceptual model, (5) ) revising the results of trials model in order to obtain a final model, and (6) composing the research reports. The development of a collaborative learning model can improve students' social skills. The increasing of students’ social skills can be seen from the skills of students while working in groups, respecting each other's opinions, helping each other in completing assignments and reminding each other in making notes in each other's books and the distribution of tasks during presentations so that each group member has the opportunity to speak

Abstract

Low levels of 'ocean literacy' has been identified in many countries and can be a barrier for citizens to engage in environmentally responsible behavior even though improving public awareness about the ocean can benefit society and the environment. This study assessed the level of knowledge, attitude, and behavior towards the ocean of students grades 10-11 (ages 15-17) in Tanjungpinang, Indonesia, a region with strong connections with the sea. A survey was used in a public school and a private school, with a total of 200 students participating in a test about ocean knowledge and a survey about ocean attitude and behavior. Many test questions were aligned with the SOLE (The Survey of Ocean Literacy and Experience) based on 'Ocean Literacy Principles' established by the Ocean Literacy Campaign in the United States. Overall, respondents possess a moderate level of knowledge, a highly positive attitude towards the ocean environment, and a moderate level category on behavior. There are significant differences: the level of behavior in terms of class level, the level of knowledge, and attitudes in terms of subject interest. There is no significant difference in knowledge between private and public schools. There is a correlation between attitude and knowledge and also between attitude and behavior
