Muara Bangkahulu District is one of Bengkulu Province Subdistricts, which is used as a place for higher education service centers, government office centers, and community residential areas. Muara Bangkahulu has the risk of being affected by an earthquake caused by its geological conditions. To avoid the potential damage due to earthquake, the PGA parameters, seismic vulnerability index, ground shear strain, and thickness of sediment layer (h) were analyzed in Muara Bangkahulu District as an effort to mitigate earthquakes. The purpose of this study is to describe the potential damage caused by the earthquake in Muara Bangkahulu District as a disaster mitigation effort. This research was a qualitative descriptive study using the literature study method. The results of the literature study which showed the value of PGA produced between 184.22 gal to 532.92 gal. Distribution of seismic vulnerability index values between 0.56 to 7.95. Distribution of ground shear strain values between 5.14 x10-5 to 7.42 x10-4. The thickness of the sediment layer (h) ranged from 8.13 meters to 61.31 meters. The largest PGA, IKS, GSS and h values are in Kualo Beach which is estimated to have a high level of risk for earthquake disasters with a correlation more than 74%. Thus, it can be concluded that the vicinity of Kualo Beach is the most potential and prone to earthquake damage.

Natural Science subject learning materials emphasize the observation of natural phenomena and their application in daily life. This research aims to foster students' concern for the environment through a learning unit book on the interaction of living things. The type of research was a "research and development method" with the design of 4-D model development research. The learning unit book was made based on the results of insect inventory on Amorphophallus titanum. The learning unit book was presented to the 8th-grade students of SMP Negeri Rejang Lebong, Bengkulu. The subject in this study was class VIII B on a limited trial. The subject was selected using the purposive sampling method. The data from the study was obtained by providing a questionnaire on environmental concerns. Analysis used test-n-Gain, and small-scale test results of environmental concern found an average score of 77.24 that are well categorized.

The aims of this study were to determine the level of feasibility of the modules developed and to increase students' creative thinking skills in the Organic Chemistry of Natural Products subject. Module development was carried out with the 4D model, namely Define, Design, Develop, and Disseminate. The feasibility of the module could be determined through the validation test with expert judgments. The ability to think creatively by students was measured using descriptive questions based on creative thinking indicators, fluency, flexibility, and elaboration. Measurements were made by comparing the results of the pretest and posttest. Next the results were tested for normality and hypothesis testing using the SPSS 20 program through the One Sample Kolmogorov-Smirnov Test. Based on the validation test by expert judgments, the modules that have been prepared have a module level of eligibility which was very valid or very feasible. The average for each indicator of creative thinking at pretest and posttest has increased. The pretest and posttest values on fluency indicators were 15.31 and 35.62 with N-gain 0.78 high category, flexible thinking (20.62 and 62.81 with N-gain 0.88 high category, and elaboration) 33.43 and 61.24 with N-gain 0.73 in the high category. After the normality test, and the hypothesis test, it was concluded that there was an increase in students' creative thinking abilities in the Organic Chemistry of Natural Products course with the use of modules.

This study aims to explain the potential of liquefaction in Padang Lekat Village and Pasar Ujung Village Kepahiang District, explaining the feasibility of developed learning packages, and explaining students' critical thinking skills after learning the wave material through the learning package "Strain Liquidity Learning". The type of study used was research and development which aims to develop digital-based physics learning packages that are integrated with disaster mitigation education on the basic competencies of waves in high school education units. This research was conducted using ADDIE development research procedures. The results of research on the analysis of liquefaction potential based on microtremor data using the Ground Shear Strain method, zoning indication of liquefaction potential due to geological conditions and seismic potential, generally Padang Lekat Village and Pasar Ujung Kepahiang Village are areas that have no potential to experience liquefaction. However, there are a number of locations indicated by potential liquefaction, although not significantly. Learning Package Book "Learning Liquid Strain" compiled based on the analysis of liquefaction potential based on expert validation is appropriate to be used as a learning medium for seismic and liquefaction waves. In its application with distance learning, the compiled learning package book has been able to improve critical thinking skills in students even though the N-gain improvement obtained is still in the low and medium categories.

The research aims to determine how to implement an online learning model to increase learning outcomes of learners. This type of research is class action research (PTK). The subject in this study was a student of class IX.7 Junior High School Number 1 Bengkulu City school year 2020/2021 amounting to 33 learners. The data was collected by using the final cycle concept comprehension test form using the google form feature. The results showed that the application of online learning models during the Covid-19 pandemic through the Cloud X application and using power point media and learning videos could improve student learning outcomes. The increase in student learning outcomes can be seen from the average scores of students from cycle I to cycle II is: 76.90; 81.12 and classical learning completeness of students is 36.36%; 78.79%.

The purpose of this study is to improve learning activities and understanding mathematical concepts by applying the Group Investigation of cooperative learning model in class VIII.6 SMP Negeri 4 Bengkulu City. This research was a Classroom Action Research. The instrument used was the student’s activity observation sheet and the student’s concept understanding test sheet. Improved learning activities can be done by: using props at each meeting, reminding students how to measure appropriately, distracting students' attention by provoking students’ ideas, and lazy group members will be designated as presenter groups. Increased student’ learning activities in the first cycle with an average of 21.5 (quite active), and the second cycle increased by an average of 28.75 (active). An increase in understanding of mathematical concepts can be done by: each student notes the important things presented by the presenter group, and is given practice questions at the end of each meeting. Increased students’ understanding of mathematical concepts seen from the average test results of students' understanding concepts in the first cycle that was 60.61 and in the second cycle increased to 76.62. The percentage of mastery learning classically in the first cycle was 39.39% and in the second cycle was 63.64%.
