Abstract

Measurement of magnetic data has been done in the area of oil seeps in the village of the Alue Punoe, with 121 measurement points as a grid within 500 m x 500 m area where each grid is approximately in 250 m2. The total magnetic field measurement has been examined by using Proton Precession Magnetometer (PPM). Upward continuation correction was applied to obtain residual magnetic field anomaly. Residual magnetic field anomaly data are mapped using the Surfer software, while subsurface models are made using the Mag2DC software. Based on the models that have been sliced from the local magnetic anomalies along the cross section of A-B and C-D from which then obtained a shallow structure which is a fault whose an approximate depth from 30 to 100 meters and three stratified media. The stratified media of the study area are interpreted as an alluvial deposit, alternating sandstone and clay and igneous rocks. Interpretation of subsurface models shows that there exists a shallow structure assumed as a fault. Expected fault has an adjacent to the manifestations which are about 50 to 70 m. It strengthens the case that the fault is strongly related to as the pathways of oil seepsfrom possibly existed petroleum system below subsurface of unknown strata

Abstract

Misconception is one of the obstacles in the achievement of physics learning and must be immediately corrected so that there is no retention of misconceptions in subsequent knowledge. One way to prevent and reduce misconceptions that occur is with the teachers skill of Technological Pedagogical and Content Knowledge (TPACK). Teachers who integrate TPACK in learning can prevent misconceptions and find solutions to overcome the misconceptions. This study aims to determine the TPACK skill of teachers in overcoming misconceptions and the appropriate TPACK components to reduce misconceptions based on concepts on the three tier test of FCI (Force Concept Inventory). The research method used is mixed method with concurrent embedded design. The main data in this study is TPACK which is qualitative data and supporting data is students misconception which is quantitative data. The results showed a decrease in misconceptions after being given an understanding of the concept using the teacher's TPACK skill. The components used during the teacher's reduction of misconceptions based on the concepts in the FCI three tier test of FCI  are TPACK and PCK components. So it can be concluded that the teacher's TPACK skill can reduce the misconceptions that occur in the three tier test of FCI

Abstract

Physics learning needs to emphasize science process skills (KPS) in students. In fact, from the results of a case study conducted at SMAN 2 Banda Aceh, it was found that the LKPD used by teachers was still conventional and there were no aspects of KPS. The purpose of this study was to determine the results of the application of physics LKPD based on the STEM approach in improving the KPS of high school students. This study used a quantitative approach of experimental type Non-Equivalent Control Group Design. The samples used in this study were X4 and X6 class students totaling seventy people taken by purposive sampling. The instrument in this study was the KPS test. Data analysis of this study used the average test, N-gain test and t-test. The results showed the average value of the experimental class KPS N-gain of 0.70 was in the high category and the control class N-gain of 0.63 was in the medium category. Based on the results of the t-test, it can be concluded that there are differences in the improvement of students' KPS in physics learning taught with the STEM approach and those taught using the direct learning model.

Abstract

This study aims to identify students' misconceptions on the material of Kinetic Gas Theory in physics learning. This study uses a qualitative approach and the type of research used is descriptive research. The subjects of this research were 20 students of class XI. The data was collected by means of a diagnostic test technique equipped with CRI (Certainty of Response Index) and free-guided interviews. The results of data analysis show that the average Lucky Guess level is 13%, concept understanding is 39%, not understanding concept is 20%, and average percentage of misconceptions are 28%. Based on the identification results, the highest misconceptions in students appear in the indicator of the question of calculating the ideal gas equation by 55%. The results of the analysis and interviews that have been carried out, misconceptions occur due to the students themselves because they do not understand the concept as a whole and the lack of interest of students to repeat the lesson.
