This research is based on the low level of mathematical creative thinking ability of MAN 1Pesisir Barat students and less optimal learning result, and there are still many teachers who apply conventional learning and also the weakness of the use of language in mathematics book and illustration which is not communicative and interactive so that does not succeed The core message of the book.Based on these issues, it is necessary to develop a mathematics learning that can provide flexibility of learners to learn to think actively and creatively in solving problems encountered, one of which learning by using modules. This research was conducted with the aim to develop a mathematics module with strategic solving to measure the level of mathematical creative thinking ability of grade XI MA students on statistical materials. The research that the writer do is a module development research with several stages of product analysis phase that will be developed, initial product development stage, expert validation stage and test and revision phase, at revision stage that is to improve the module that has not met the module feasibility test standard, Ideas and suggestions from experts. In product trials, data collection is obtained by using test instruments with statistical materials, inscribed essay-form tests ability level of students' mathematical creative thinking. Based on the results of research and data processing obtained the results of pre-test learning value with an average value of 20.0645, while the value of learning post-test has an average value of 39.6774, seen from the value known that there is an increase in student learning outcomes by the difference Class of 19,6129. So that the mathematics module with strategic problem solving with statistical material can measure the level of students' mathematical creative thinking ability.
Tujuan penelitian ini adalah untuk mengetahui apakah ekstrak daun binahong dapat menghambat pertumbuhan bakteri Propionibacterium acnes. Penelitian ini merupakan penelitian eksperimental laboratorium dengan menggunakan Rancangan Acak Lengkap (RAL) dengan lima perlakuan. Perlakuan diulang sebanyak 3 kali dengan berbagai macam konsentrasi dari 20%, 40%, 60%, 80%, dan 100%, serta klindamisin sebagai pembanding dan aquades sebagai kontrol. Ektrak daun binahong diperoleh dari maserasi daun binahong dengan pelarut metanol dan dipartisi dengan menggunakan pelarut etil asetat, kemudian dilakukan uji aktivitas antibakteri terhadap bakteri Propionibacterium acnes. Parameter yang diamati adalah diameter zona hambat pertumbuhan bakteri Propionibacterium acnes. Analisis data menggunakan ANOVA (Analysis of Variance). Hasilnya diketahui bahwa ekstrak daun binahong memiliki kemampuan menghambat pertumbuhan bakteri Propionibacterium acnes terlihat dengan adanya zona hambat yang terbentuk. Konsentrasi yang paling efektif menghambat pertumbuhan bakteri Propionibacterium acnes adalah pada konsentrasi 100% sebesar 9,00 mm pada waktu 24 jam dan 11,20 mm pada waktu 48 jam.
This research is a qualitative research with the qualitative descriptive method. The technique of research subject taking in this research use purposive sampling technique. The subjects of this study amounted to 9 students. Data collection techniques used were questionnaire perception and disposition of students' mathematical creative thinking, observation, interview and documentation of mathematics learning. Data analysis techniques, namely data reduction, data presentation, and conclusions. The validity of data in this study using the content validity, construct validity and reliability and triangulation techniques. According to the results of the study and discussion, the conclusion of this study is Based on the gender and disposition of mathematical creative thinking, the perception of mathematics learning that is produced, that is for high DBKM and positive perception is only found in male students, for high DBKM and medium perception, Male and female students, for medium DBKM and medium perception, female students tend to be more than male students, for medium DBKM and negative perceptions of male students tend to be more than female students, for low DBKM and perception is being Only in boys, and for low DBKM and negative perceptions are only found in female students. The disposition of high mathematical creative thinking and positive perception is very influential on learning mathematics because students who have high DBKM and positive perception will be better in learning mathematics than students who have DBKM and perceptions other than high DBKM and positive perceptions of mathematics learning.
The purpose of this research were to find out the difference in effectiveness between WEE model with QSH strategy and conventional learning, the difference between high, medium and low Self Regulation, and the interaction between learning model and Self Regulation towards the student's ability of understanding mathematical concept. This research was Quasy Experiment, population were all of Class X Science SMAN 14 Bandar Lampung academic year 2018/2019. The sample class used were two classes by using technique Cluster Random Sampling. Hypothesis testing using two-way ANOVA with .The results of this research were: (1)WEE model with QSH strategy more effective than conventional model learning towards the student's ability of understanding mathematical concept. (2)The ability to understand mathematical concept with high Self Regulation is better than medium and low Self Regulation, whereas there was no difference between medium and low Self Regulation. (3)There was no interaction between learning model and Self Regulation towards the student's ability of understanding mathematical concept.
