Abstract

Indonesia is a country located at the confluence of the Indo-Australian and Eurasian plates, which collide with each other, one of which is off the west coast of the island of Sumatra. This situation carries a significant risk of triggering a tsunami disaster. To minimize these risks, it is necessary to provide disaster awareness to all groups, especially students. This study aims to produce an e-booklet on integrated wave material for tsunami disaster mitigation on the outermost islands of Sumatra's west coast. The study employs a research and development methodology. The research instruments were questionnaires, interview guides, validation sheets, and questions. We conducted descriptive, quantitative, and qualitative data analysis. The research results led to the production of an integrated e-booklet for tsunami disaster mitigation, tailored to the region's potential in mitigation efforts. The level of disaster preparedness after using the e-booklet is included in the high preparedness category. The relationship between knowledge and level of disaster preparedness is linear. So that this e-booklet can be used as teaching material to provide disaster preparedness on the outermost islands of the west coast of Sumatra.

Abstract

This research was carried out in September-October 2023 at the Bengkulu University ex-situ turtle conservation area, aiming to provide comprehensive knowledge about roaming patterns, active times, and movement areas in artificial habitats so that they can be used to develop effective conservation strategies for maintaining the preservation of C. amboinensis in the ex-situ turtle conservation area, Bengkulu University. This study observed 11 individual turtles (4 females and 7 males). This research uses literature study methods and direct observations in the field. The results obtained showed that C. amboinensis had: high mobility because all artificial areas were explored. The active time of C. amboinensis is in the morning and evening. The range of movement of males is greater than that of females. Mounting activity occurs spontaneously or directly when male C. amboinensis and female C. amboinensis meet in a certain area. The roaming pattern of C. amboinensis occurs randomly and the range of movement between male and female C. amboinensis is very different.

Abstract

The aim of this study was to determine the motivation of science teachers and students towards science after participating in the activity of assembling, simulating, and recording line follower robots as an effort to motivate middle school students and teachers towards science in Bengkulu Province. The research was done by direct practicing, where 60 students and 15 teachers of three junior high school (SMP): SMP Negeri 06 Seluma, SMP Negeri 02 Kota Bengkulu, and SMP Negeri 8 Rejang Lebong, were involved as the research subjects. The research activity concluded that the schools are ready to prepare simple electronics/robot laboratories for the three research subjects and the science teachers and students were motivated to learn science. It was seen from the score of 3.95 (scale of 1 to 5) for students, and for the science teacher, the score was 3.83 (scale of 1 to 5). The science teachers will follow up on robotics activities so that students will be interested in learning science at home and school.
