Abstract

This research was conducted to determine the quality of antidiabetic traditional medicines from beans and bitter melon after 6 months of storage. Beans and bitter melon contain bioactive compounds such as flavonoids, beta sitosterol, stigmasterol, alkaloids, saponins, and phenols which function as antidiabatic. However, environmental factors such as production processes, and environmental temperatures affect the storage process. So we need to test the quality of antidiabetic drugs after 6 months of storage. The tests are pH test, total plate number test, mold and yeast number test. Based on the test the following results are obtained. The pH obtained was 4.75, the plate number was 0.002 colonies / g, mold number and yeast 0.01 x103 colonies / g. Based on these results, the quality of antidiabetic traditional medicines from beans and bitter was kept in quality after 6 months of storageKeywords: Quality of storage, traditional medicine, beans, bitter melon

Abstract

Research on student creativity at The Study Program of Physics Education FKIP Universitas Mataram for Wave and Optics course was conducted. This study aims to describe student creativity in the creativity of solving problems related to wave and optical matter. Tests were given to 21 students as samples with a test format following the principle of multi-representation on wave and optical questions. This test emphasizes the creativity of students' cognitive thinking which includes fluency, flexibility, originality, and elaboration. The results of cognitive thinking creativity in problem solving creativity showed that 38% were good and 68% were quite. Thus the mapping of the level quality of cognitive thinking creativity the students of Physics Education at FKIP Unram in the odd semester of the 2018/2019 academic year is generally at the level of being quite creative.Keywords: cognitive thinking creativity,  multi-representation

Abstract

Producing active charcoal to be absorbent for ion Fe2+ and Co2+ had been done by using waste of bagasse. The objective of study was to utilize waste of bagasse to be active charcoal, so it can be used for absorbent. Initially, it was carbonized by using pyrolysis at temperature of 300-400oC for 5 hours. Then, it was activated by solving to ZnCl 2 10% for 24 hours, filtered and washed by using distilled water. Wet active charcoal was drained in oven for 9 hours at temperature of 110oC. After that, the analysis stage was started by inserted the absorbent into 10 mL samples which are contained various concentration of ion Fe2+ and Co2+ with variation of 1 gram, 2 grams, and 3 grams for 10 ppm solution. The, it was stirred by contacted time of 10, 20, and 30 minutes. By the previous treatment, it was indicated that the best contacted time for Fe2+ is 30 minutes with 3 grams absorbent which is showed by color change from yellow to colorless with a removal percentage of 95%. For the same case, Co2+ has removal percentage of 98% for 3 grams absorbent with contacted time of 30 minutes which is showed by color change from pink to faded.

Abstract

Lack of understanding of concepts and facts in the Evolution subject leads to low activity and student learning achievement. That are caused students simply expect information from lectures who are still using regular discussion. The purpose of this research is to improve the activity and student learning achievement at the Evolution course. Learning activities that are studied, among others asking, answering questions, the moderator, presenter on discussions, and taking note of the lecturer. This type of research is a class action research in the class that may have activity and low learning achievement. Learning achievement assessed is cognitive aspect only the cognitive. Increasing of activity and student learning achievement will be done by using the method of group learning plenary discussion. It a method in which all participants can be used to describe a particular topic or concept so the understanding of the participants are expected to be the same. Application of the method plenary discussion on the course of evolution can improve the activity and student learning achievement of Biology education students of STKIP PGRI of West Sumatra

Abstract

This research aims to know the effect of group investigation learning on student’s science process skill based on their IQ in SMAN 1 Mataram for eleventh grade students. This is a quasi experimental study using pretest postest control group design design. Pretest was taken to get data of student’s IQ. Posttest was also conducted to measure student’s science process skill. Sample was taken using nonprobability sampling from the population of eleventh grade student in SMAN 1 Mataram.The sample was two group of student each from two class, class XI sains 6 and as experimental group and class XI sains 5 as control group. The average os Student’s IQ on experimental group and control group were equal, both at 112. Learning processes were 12 x 45 minutes long in total. The experimental group showed better average score on posttest where they scored 82.40 on average, while control group only scored 74.83 on average. This value is statistically significant, at p = 0.007, less that 0.005. This result shows that implementation of group investigation can increase student’s science process skill.Keywords: Group investigation, science process skill, intelligence Quotient (IQ)ABSTRACT
