The Process of Establishing and Activities of the Anak Krakatau Mountain
No full textAnak Krakatau is one of the legendary mountains which was the result of the eruption of Mount Krakatau in 1883. The Krakatau area was divided into three regions, Krakatau Island, Sertung Island, and Mount Anak Krakatau. The activity of Mount Anak Krakatau in 1929 tended to be active, because in a year Anak Krakatau could experience eight eruptions. This can be seen in visual observations starting from 1929-2000 experiencing a fairly rapid development. At the end of 2018, Anak Krakatau erupted again, where the eruption caused a landslide to part of the mountain's side. As a result, the debris from the landslide, made the waters of the Sunda Strait unstable, thus forming a tsunami wave. Eruption did not only happened in 2018, Recently, Anak Krakatau became active again in 2020 by releasing its volcanic ash. The activity of Anak Krakatau which underlies the purpose of this study, namely knowing the formation process and activities of Mount Anak Krakatau. So that in the future further research can be carried out related to disaster mitigation efforts from the eruption of Mount Anak Krakatau in the area around the mountain. The analysis process used is a literature study using related journal articles and data on the cataclysmic events of the Anak Krakatau volcano eruption

The Result of Second Field Test of Cellulose Degrading Bacteria from Mangrove Soil Microbiology Handout
Get PDFLearning media is one of the most important component in a learning process, both inside or outside a classroom. In order to provide proper learning for students based on the researcher’s prior research, at least, three different field tests are needed. This research is a quasi-experiment, which is provide result of the second field test of cellulose degrading bacteria from mangrove soil microbiology handout both in cognitive and psychomotor ability. The research aims are to describe effect of this microbiology handout on student’s cognitive achievement and gain data about inappropriate laboratory written instruction in this handout. Data gained by conducting learning activities using developed handout which were 2 times in class theory and three times of practical activity using instuctions written in the handout. In the end of class theory activity, students did a posttest to confirm their improvement of cognitive ability while their practical ability was observed using observation sheet along with their activities. Results showed that handout which being tested could improve student cognitive at average level (n gain 0,419). In contrast, several parts of laboratory written instruction need to be fixed to make better microbiology handout.Â
Development of Mathematics Learning Design through Problem Posing Approach for Developing Mathematical Reasoning Ability
No full textThis study aims to produce a mathematical learning design through a problem-posing approach that improves student's mathematical reasoning abilities with valid, practical, and effective criteria. This type of research is research and development. The subject of this development trial is students of grade VIII-9 of SMP Negeri 1 Bau-Bau. The devices and instruments that have been compiled are validated, and the validation results show that they meet the validity requirements. The practicality of the design is shown by the average percentage of achievement from the observation of teacher activities, which meets the practicality requirements. Learning design meets the requirements of effectiveness, namely the average achievement of student activities with good criteria, reasoning abilities of high category students with an average of 78,3, and the average student response to learning and worksheets is positive. Based on the result, it can be concluded that the learning design of mathematic through the problem-posing approach to improving student's mathematical reasoning ability were valid, practice, and effective
Geometric Reasoning Ability Based on Van Hiele Theory by Geogebra Software
No full textThe difficulty of students in solving geometric reasoning problems which are based on Van Hiele’s levels is still low so that the right alternative solution is needed. For that reason, this research aims to answer those three main objectives. First, this study determines the difficulty experienced by the students. At second, this research identified the factors which cause the difficulty experienced by students in solving geometric reasoning problems based on van Hiele theory by GeoGebra software. At third, this research tried to determine the steps which are required to be taken to overcome the students’ difficulties in solving geometric reasoning problems based on van Hiele theory by GeoGebra software. The type of study is a descriptive study with a qualitative approach. The results showed that students’ geometrical reasoning ability was still in the low category; the causal factors are the students were rarely trained in geometric reasoning and lack of self-confidence. The step that should be done is by using van Hiele theory to detect the difficulty experienced by the students, including technology media such as GeoGebra software
