Abstract

A microgravity investigation on bedrock topography was conducted at Maluri Park in Kuala Lumpur, Malaysia. The study characterized the subsurface structure to delineate soil structure for the geotechnical application. Cross-section modelling of the residual anomaly generated the Maluri Bouguer Anomaly model for test site. The 2D microgravity models produced the contour map, displaying the characterization due to density contrast in rock types while mapping the subsurface geological structure at different depths. Moreover, a synthetic model was initiated with the assumption of lateral distance on the left and right sides taken at 50 m and a depth of 60 m. The results of modeling confirmed that the soil and rock type composition on models test site, i.e: topsoil (1.1 g/cm3), soil (1.8 g/cm3), clay (1.63 g/cm3), gravel (2.0 g/cm3), sand (1.7 g/cm3), shale (2.40 g/cm3), sandstone (2.76 g/cm3) and limestone (2.9 g/cm3). The 2D gravity synthetic model show a good match with the observed microgravity data.

Abstract

The objective of this study is to describe the relationship between teacher performance and learning outcomes in high school students in Kendari. The research method used is descriptive correlative with the sampling technique using proportionate stratified random sampling. The research instrument is using a questionnaire of physics teacher for grade XII high school and the results of national exam the 2018/2019 academic years, by respondents consisting of 15 teachers and 692 students. Data analysis uses pearson product moment correlations. The results are showed that teacher performance has a linear correlation of student learning outcomes with a correlation value (r) of 0.533 or 53.33% and 46.67% determined by other factors such as: the hierarchical relationship between the head master by teachers and staff, who are not established yet. On the other hand, management of school organization is not optimal. The results of this study can be used as a basic for policy making for the Education and culture office in Kendari city to apply the relationship patterns of  teacher performance and student learning achievement.

Abstract

The aim of study is to investigate the impact whatsapp-blended learning implementation of SMKN 2 Kendari student’s understanding of electricity learning. The study is quantitative research with pre-experimental way while using one group pretest-posttest design of research. Moreover, a research sample is taken by the method of probability sampling which is kind of simple random sampling. A technique of data collecting uses to test and non-test (questioner). A technique of data analysis uses descriptive statistic and inferential statistic. The results of this study show that the average value of student’s abilities to understand the physic concept on pre-test which is representatively 43.72, while in the post-test it is 88.00 while in the post-test it is 88.00 with an average n-gain of 0.78. The study shows that blended learning application generally takes a great response of students, which stood on 64.48% of the average scores.
