Abstract

[Title: The Effect of Thinking Aloud Pair Problem Solving Learning Model Toward Student Physics Science Learning Outcomes]. This research aims to know the effectiveness of the learning problem based learning model assisted work sheet for the critical thinking ability of physics students of grade X SMAN 1 Lingsar inacademics year 2016/2017. This was an experiments research that using design research Posttest-Only Control group Design. The population in this research were the whole grade X SMA Negeri 1 Lingsar in academics year 2016/2017. Sampling taken with using cluster random sampling technique with the students of class X. MIA. A as experiments class and grade X. MIA. D as controls class. Research hypothesis was analysis with the t-test for one party (the party right). Based on the hypothesis test results obtained tcount> ttable at significance level of 5%, then it can be inferred that the model of learning problem based learning assisted work sheet effective for critical thinking ability of physics students SMAN 1 Lingsar.

Abstract

[Title: The Effect of Contextual Teaching and Learning (CTL) Model with Student Worksheet Assistance toward Physics Learning Outcomes of Attohiriyah Bodak High School Students]. This research aims to determine the influence of Contextual Teaching and Learning model with student worksheets toward student’s physics study result at SMA Attohiriyah Bodak in academic year 2015/2016. The type of this research was quasi-experiment with nonequivalent control group design.  The population in this research were all students in X grade SMA Attohiriyah Bodak with amount student 149 spread out into 6 class. The sample of this research is XB as experiment class and XE as control class were drawn by purposive sampling. The study result obtained was analysis with t-test separated varians, and the results showed tcount = 3.78 and ttable = 2.01 in significant standard 5% and released standard 5. Because Ho rejected and Ha accepted. So, we can conclude that contextual teaching and learning model with student worksheets positive influence toward student’s physics study result at SMA Attohiriyah Bodak academic year 2015/2016

Abstract

[Title: Chitosan/PVA Composite Nanofiber Biocompatibility Test as a Wound Wrap]. This study aims to make chitosan-based nanofiber from NTB local crab shells. The manufacture of nonofiber is intended for application in the medical world as wound dressing. Wound dressing was developed from the basic ingredients of chitosan from NTB local crab shells. This research was conducted using the electrospining method, namely by making fibers from nano-sized chitosan. The resulting wound dressing was analyzed using FTIR. The results of this analysis show that chitosan has an area of absorption or transmittance in some chitosan groups so that it shows a positive alloy on chitosan and PVA as antibacterial in wound dressing.

Abstract

[Title: The Effect of Inquiry-Based Active Learning (ABI) on Students' Critical Thinking Ability]. The critical thinking ability is the ability to learn and analyze information through skills: interpretation, analysis, evaluation, inference, explanation and self-regulation. Inquiry-based active learning model (ABI) is a learning model that accumulates active and inquiry learning which aims to develop students critical thinking ability through phases: 1) introduction and establishing sets; 2) presenting cognitive conflicts; 3) submitting the hypothesis; 4) collecting data (experiment) for hypothesis testing; 5) formulate explanations and/or conclusions; 6) reflection. This research aims to determine the effect of inquiry-based active learning model (ABI) on students’ critical thinking ability. This research is quantitative research (quasi-experiments), this experimental research uses pretest-posttest control group design. This research is used cluster random sampling. The sample in this research amounted to 37 students as experimental class and 34 students as control class. The inferential analysis is used to test the influence of inquiry-based active learning model (ABI) in a review of improvement of students’ critical thinking ability. Hypothesis test results also show t-test value lower than t-table value, so it can be stated that the Inquiry-Based Aktive Learning Model (ABI) has a positive effect on critical thinking ability of X-GEO at SMKN 3 Mataram school year 2017/2018.

Abstract

[Title: The Effect of Thinking Aloud Pair Problem Solving Learning Model Toward Student Physics Science Learning Outcomes]. This study aims to determine the effect of learning model Thinking Aloud Pair Problem Solving on the results of science learning Physics Class VIII SMPN 6 Praya Timur. This research is a quasi-experimental research with Posttes -Only Control Design research design. The samples of this research are taken using Purposive Sampling technique with class VIIIc as the experiment class is 24 students and VIIId as the control class is 24 students. The instrument used in the form of test description in the form of 10 questions that are tailored to the learning indicators. The result of data analysis obtained using t-test at 5% significant level shows that the value of tcount> ttable (tcount = 0.634 & ttable = 0201) then Ha in receipt. so it can be concluded that the learning model Thinking Aloud Pair Problem Solving can affect the results of science learning Physics Student.

Abstract

[Title: The Effect of Thinking Aloud Pair Problem Solving Learning Model Toward Student Physics Science Learning Outcomes]. This study aims to test mechanical on membrane composite membrane based crab shell and poly vinly Acetat (PVA). A mechanical test was performed to test the young modulus of the membrane in maintaining pore size using the "Tensilon" machine. The results show that chitosan / Poly Vinly Acetate composite membrane with preparation of comparison 25% -75%, 50% -50% and 75% -25%. For sample 25% -75% experience drying process faster than other sample. On the mechanical test of chitosan membrane / Poly Vinly Acetat showed the biggest value that is equal to 9.84 Mpa on comparison preparation 50% -50%. 25% -75% and 75% -25% preparations decreased by 4.68 MPa and 1.37Mpa.
