In magnet world learning, the discussion of the µ magnetic permeability concept has not yet been addressed specifically. The magnetic permeability often discussed is the µ0 vacuum permeability whose value is 4p x 10-7 Tm/A. In fact, the permeability value of objects is not the same as the vacuum permeability. Therefore, it is necessary to conduct experiments on this in order to obtain an adequate understanding of its concepts. The experimental devices include Logger Lite devices, solenoids, computer, power supply, and two types of ferromagnetic materials i.e. steel and white metal which are precisely similar in both lengths. The deciding of the material permeability is done by placing the materials on the solenoid varying electric current (i) which flows in the solenoid and records the induction field produced (B). Then, based on the data set of I towards B, it’s done a linear regression. The material permeability is determined from the slope of the graph.Based on the experiment, the permeability value of vacuum results mo = (4p ± 0,34) x 10-7 Tm/A. Whereas, for each experimented material it shows that the steel is is m = (8.24 ± 0,008) x 10-6 Tm/A and the white metal is m = (1.85 ± 0,002) x 10-5 Tm/A. Based on the experiment, it’s obvious that the permeability concept seems more and more tangible.

This study aims to determine the differences in student physics learning outcomes using comic learning media with learning module media on the recitation method. This research was conducted at Gunung Putri 2 High School in the second semester of the 2017-2018 school year. The population of this study was taken as many as 60 students from a population of 65 students. The sampling technique used is simple random sampling technique. This study uses a quantitative approach with a quasi-experimental method. The results showed that in the experimental group I obtained normality test Lhitung = 6.062 <7.81 = Ltabel and experimental group II obtained Lhitung = 0.70 <7.81 = Ltable at the significance level α = 0.05 and n = 30, then it can be concluded that the two groups are normally distributed. For the homogeneity test, it was found that Fcount = 1.211 <1.87 Ftable, it can be concluded that the variance between the two groups is the same, meaning that the sample comes from a homogeneous population. Hypothesis testing using t-test obtained by t count = 5.01> t table (α = 0.05; db = 58) = 1.643 and t count = 5.01> t table (α = 0.01; db = 58) = 2.66 , then H0 is rejected. Thus, H0 is rejected which states that there is a difference between student physics learning outcomes using comic learning media with learning module media on the recitation method.

Abstract – Laboratory demonstration tools is learning medium that teachers use as an alternative to improve students’ understanding. Founded that students understand the concept that is taught but some students still have difficulty in solving the problem. This study aims to describe the profile of students' thinking processes presented through laboratory equipment by analyzing student behavior as learning takes place based on information processing theory. This research is a naturalistic qualitative research in which the research takes place naturally and not conditioned. Subjects in this study were 2 students of SMKN in Salatiga with high and low academic category. The result of the students' thinking process descriptions show that subjects with high academic categories are able to process the stimuli in selective attention more fully from subjects with low academic categories, the two subjects perform a perception process against the stimulus correctly, the rehearsal process performed by subjects with high academic categories stimuli more frequently than subjects with low academic categories, subjects with high academic category are able to perform the encoding process well while the subject with low academic category were not, and subjects with high academic category can perform the process of retrieval smoothly while subjects with academic low category have difficulty difficulties. The lack ability to process information can decrease the ability to solve problems. The suggestion for educators is that they must provide a complete record of learning outcomes and provide conceptual application for learning objectives to be achieved.

Abstract – This study aims to: (1) Determine the feasibility of developing a CORE-based Physics handout. (2) Determine students' responses to the use of CORE-based Physics handouts. (3) Knowing the increase in students' HOTS after the use of a CORE-based Physics handout in the learning process. The type of research carried out is research and development, using the ADDIE development model. The stages include, analyze, design, development, implementation and evaluation. Product trials were conducted for students of class X MIPA program in SMA Negeri 1 Pejagoan. To get the interpretation of the data obtained, data analysis is performed by changing the score from a scale of four into a percentage. Then calculate the value of the Percentage Agreement (PA) to determine the reliability of the implementation of learning. As well as normalized gain to determine the increase in HOTS of students from the results of pre-test and post-test. The results of the validation test, the average of the three validators was 3.48. So that this CORE-based Physics handout is in the "good" category and is appropriate for use in learning Physics. Student response test produces a score of 2.96 with the category "Enough". This CORE Based Physics Handout can improve high order thinking skills on the cognitive aspects of high school students in class X SMA N 1 Pejagoan with a normalized gain of 0.6981 in the "Medium" category. These results indicate that the CORE Based Physics Handout can be an alternative teaching material for high school physics learning.

Abstact - Research has been conducted to develop a Model-Eliciting Activities (MEAs) handout with multiple representations that are feasible and able to improve students' mathematical modeling abilities. The research design refers to ADDIE namely analysis, design, development, implementation, and evaluation. This research was conducted in SMA Negeri 2 Purworejo with research subjects in a limited trial of 10 students, and 32 students in the application phase. Product trials using a posttest-only control design. Data collection techniques using observation, questionnaires and tests. The results of data analysis namely the quality of handouts can be seen from the aspects of validation, the implementation of learning, students' responses to the handouts and completeness of learning outcomes. The results of the MEAs handout validation with multiple representations of three validators, namely two expert lecturers and physics teachers with an overall assessment score of 3.52 (very good). The percentage of the learning outcomes of the four meetings was 90.39% (very good). Students' responses to the handout obtained a percentage of 84.51% (good). The percentage of completeness of learning outcomes using handouts in the experimental class was 78.13%. Increasing or not the ability of mathematical modeling using hypothesis testing with t-test statistics obtained t-count of 4.548 where the magnitude of t table is 2,000 with a significant level of 0.05. H0 is rejected if the test criteria in the hypothesis test are t_count> t_table = 4,548> 2,000 then the use of Model-Eliciting Activities (MEAs) handouts with multiple representations can improve mathematical modeling abilities. The assessment results indicate that the developed handouts have good quality and can improve mathematical modeling abilities.

This study aims to find the Effect of Discovery Learning with Problem Based Learning to Result of Study in terms of Student Activity. The method used in this study is the True Experimental Design method. Based on the results of hypothesis testing using Two Path ANAVA, the first hypothesis obtained a value of Fhitung= 12.56 > Ft(α=0.05)= 4.06 ; Ft(α=0.01)= 7.24, while for the second hypothesis Fhitung=26.40 > Ft(α=0.05) = 4.06 ; Ft(α=0.01) = 7.24. Then for the third and fourth hypotheses can be calculated using the t-Dunnet test, the value thitung= 9.05 > tt(α=0.05)= 1.678 ; tt(α=0.01)= 2.411 and thitung= 5.64 > tt(α=0.05)= 1.678 ; tt(α=0.01)= 2.411. So from the results of this study it can be concluded that there is an Effect of Discovery Learning with Problem Based Learning to Result of Study in terms of Student Activity.
