Abstract

This research aims to determine the influence of cognitive style on students' critical thinking abilities. This research uses a quasi-experimental method with a factorial design research design. The research subjects consisted of class XI MAN 1 Central Lombok students who were divided into experimental classes and control classes. The experimental class uses the PBL model, while the control class uses a conventional learning model. Research instruments include critical thinking ability tests and the Group Embedded Figures Test (GEFT) cognitive style test. Before the critical thinking ability test instrument is given, a test of the instrument is first carried out, namely a validity and reliability test. level of difficulty, and distinguishing power. The research results show that the significant level value is 0.001 which is smaller than α which is equal to 0.05 (0.000<0.05). These findings indicate that there is an influence of cognitive style on students' critical thinking abilities.

Abstract

The purpose of the research to determine the effect of Project Based Learning (PjBL) model on student learning outcomes in optical instruments. The sampling technique used purposive sampling, obtained class XI MIPA 4 as experimental class and XI MIPA 5 as control class. The research design used was a nonequivalent control group design. The experimental class will be given treatment using the Project Based Learning (PjBL) model, while the control class will use the expository model (conventional learning). Learning outcomes abilities measured in the cognitive domain include: C1) remembering, C2) understanding, C3) applying, C4) analyzing, C5) evaluating, and C6) creating. The instrument used was 10 multiple choice questions. Data were analyzed using parametric statistics, namely Manova. The results showed a sinificance value of 0.000 < 0.05 and a value of Rcount > Rtable where 0.359 > 0.350, so H0 was rejected and Ha was accepted. So can be concluded that there is an influence of the Project Based Learning (PjBL) model on scientific literacy and student learning outcomes in optical equipment material.

Abstract

A tensimeter is an instrument works with concept of physics used to measure blood pressure. The measured blood pressure is the relative pressure between the pressure inside the blood vessels compared to the pressure of the atmosphere. Blood pressure measurements using a digital tensimeter are much more acurate than measurements using a aneroid tensimeter. Measurements with an aneroid sphygmomanometer at a hospital in the city of Mataram showed a measurement error up to 20 mmHg compared to a digital sphygmomanometer. Source of error consist of two main factors ie. Instrument error and human error. From this research it was found that measurements using a digital sphygmo-manometer are more accurate, so the use of this type of sphygmomanometer is highly recommended for clinical measurements in hospitals and health hospitals.
