The purpose of this study was to determine the profile of students’ science literacy on landslides disaster mitigation in Semarang City. This research method is a quantitative description with one shot case study. The sample of this research was the 10th grade students of SMA N 7 Semarang who were taken by using purposive random sampling technique. Data collection techniques used written tests, questionnaires and interviews. For data analysis using data triangulation technique in order to obtain qualitative descriptive data. The results showed that students’ ability to mitigate landslides from the aspects of scientific literacy which included aspects of knowledge, context, competence and attitudes was still low.
Modeling of time lapse microgravity anomaly have done. The modelling was done with two ways are first gravimetri position on the earth’s surface, and second position at a height of 25 cm from it. The first model shows for 30 % rock porosity than any change in groundwater within depth 1 meter causes gravity change 12,579 μGal. The second model show that reduction of groundwater wil reduce time lapse microgravity vertical gradient (TLMVG) anomaly. Reduction of groundwater will provide TLMVG negative value (-) and reverse groundwater give positive value (+). It was concluded that in the Kota Lama during the range of March to September there was no subsidence, but there was a decrease in groundwater level of 1.449 m
The purpose of this study was to monitor the subsidence that occurred in the Kota Lama. The method used is the micro gravity method. Measurements were carried out 2 times in the period May and September 2017. The anomalous data obtained time lapse microgravity anomaly which were the weight difference between the period of September and May. This anomalous data still contains anomalous sources of groundwater leve changes which are then corrected with rainfall data for that time interval. Finally anomaly data were obtained which were the target of the study in the form of microgravity anomaly data due to subsidence. After being converted with a constant free air correction resulted in a maximum subsidence of 0.3 cm or 3 mm occurred in the north and south of the Kota Lama.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
