Abstract

Abstract: The characteristic of the material of environmental pollution requires the real object from surrounding as learning resources. Hence, it demands the students move in or out of the classroom activity. Therefore, it is required to develop a student’s worksheet based on experiments that are expected to explain the theory about nature that can be revealed by experimental activities, especially on the material of environmental pollution. This study was Research and Development from the thiagarajan model of 4 D (Define, Design, Development and Disseminate). However, this study was conducted until the development stage only without the disseminate stage, because this study did not use it for a large scale. The instruments used in this study were validation sheets and respondent questionnaires for student’s worksheets based on experiments. The result of this study showed that the validity percentage based on the value of three expert validators with an average of 93,52 % included the very valid category. Meanwhile, the average percentage results of the respondent questionnaire included very applicable category from the first and the second tryouts were 90,98 % and 89,16 %, respectively. In conclusion, student’s worksheet based on experiments can be stated as the teaching materials which has been validated and very applicable to be used in the learning process. Keywords: Student’s worksheet based on experiments; Environmental pollution; Development

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

A thin layer of tin oxide with doping Fluorine was synthesized using the sol-gel spin coating method. The synthesis aims to determine the quality of thin layers formed based on temperature variations and the number of layers. The basic material used is SnCl2.2H2O, while the doping material used is NH4F with variations in concentrations of dopants 0, 5, 10, 15, 20 and 25%. The substrate used is glass with a size of 10 x 10 x 3 mm. The synthesis of the thin layer includes substrate preparation, sol-gel making, thin film making, and heating process. At this stage SnO2:F is deposited on a glass substrate with sol-gel spin coating technique at the concentration of sol 1 M with doping levels of Fluorine 0, 5, 10, 15, 20 and 25%, and treated with maturation for 24 hours. Making a thin layer using a spin coater at a speed of 2000 rpm for 3 minutes. The layer made consists of one layer, two layers, three layers and four layers. The resulting layer shows that the higher the doping percentage, the higher the transparency of the layer. In addition, the more the number of layers, the lower the transparency level. Keywords: Thin Film, Tin Oxide, Fluorine, Sol-gel, Spin Coating

Abstract

Abstract: This study aims to find out how misconceptions experienced by high school students on work and energy material. The method used is a mixed-research method. Data collection was carried out on 288 science students of grade XI at State Senior High School 8 in the City of Jambi using instruments in the form of four-tier diagnostic tests and interviews. The results showed that the average misconceptions experienced by students in the work and energy materials are classified in the low category because the average percentage obtained is 24%. The sub-concept sequences identified were the misconceptions of which had the highest percentage, namely: effort and potential energy (80%); the relationship between kinetic energy, potential energy, and mechanical energy (43%); and positive and negative efforts (23%). Keywords: Identification; misconception; effort and energy

Abstract

This research was conducted to find out the capabilities of endophytic bacteria isolated from flowers of the clove plants in inhibiting the growth of bacteria Streptococcus mutans, Staphylococcus aureus, Klebsiella pneumoniae and Escherichia coli and to identify endophytic bacteria that potensial to produce an antibacterial. Stages of this research include the isolation of endophytic bacteria from flowers of the clove plants, antibacterial test, and molecular identification based on 16S rRNA. Isolates of endophytic bacterial of clove plants flower produce 5 isolates, 4 isolate inhibited the bacteria S. aureus. Based on 16S rRNA molecular identification, endophytic bacterial isolates of clove plants flower which have inhibitory closely related to Bacillus amyloliquefasiens, Staphylococcus epidermidis 1034 MPA and Bacillus cereus JL.

Abstract

This research aims to determine the effect of cooperative learning on cognitive learning outcomes in terms of students' academic abilities. This study was aquasi-experimental research design with non-equivalent pretest-posttest control group design with 2x4 factorial design. The study population was a student of biology education STKIP Bima semester IV, total of 8 classes with a number of 336 students. Samples were obtained through a simple random sampling technique, of which there are 8 classes taken 4 classes as the sample with 168 students.The research instrument is a cognitive achievement test. The data were analyze dusing statistical techniques Anacova two paths. The results showed that 1) There is influence of cooperative learning model type STAD, Jigsaw II, and the TGT to the cognitive achievement of students (p <0.05), 2) There is influence of academic ability on the cognitive achievement of students (p <0.05) , 3) There is no influence to interaction effect between cooperative learning model type STAD, Jigsaw II, and TGT with academic ability of the student cognitive learning outcomes (p> 0.05), 4) Different test results show that the cooperative learning model TGT significant differences in their effects oncognitive learning outcomes, compared with Jigsaw II, and STAD (coefficient positively and sig. <0,05).

Abstract

One of the fundamental problems for students is the low motivation to learn. The reason is the learning approach used by lecturers in the classroom is less attractive. Therefore this study about the use of contextual approaches based on e-learning to help student motivation. This type of research is quantitative research, with descriptive statistical analysis and inferential statistics to describe motivation data for learning simple harmonic wave material Students of Physics Education Study Program at University of Flores use a contextual approach based on e-learning. Data collection techniques used in this study were non-test techniques. From the results of descriptive analysis shows that the average student learning motivation is 78.90 in the sufficient category. While the results of inferential statistics show the t value of 5.453, sig (2-tailed) 0.000. Because the sig (2-tailed) value of 0,000 is smaller than 0.05, this shows that the contextual approach based on e-learning (Zoom Cloud Meeting) influences student learning motivation
