Abstract
The objective of this research was to discern the differences between the Concept Attainment Model and the Treffinger model on students’ learning outcomes of the cognitive and affective domains. The sample of the research consisted of XI Science 5 and XI Science 4 students collected by employing the random sampling technique. The researcher managed using a quasi-experimental design. The obtained data were analyzed using normalized-gain through Microsoft Excel 2010 to know the increase in students’ academic achievement. The data of the Pre-test and Post-test was statistically examined by administering a normality test, homogeneity test, and t-test. The average cognitive domain on concept attainment class showed that N-gain was 0.37 and 0.58on Treffinger class. The statistical examination further showed that tobserved>tcritical which meant H0 was rejected and H1 was accepted. The average effective domain was 82.87% for concept attainment class and 84.90% for the Treffinger class. Treffinger model, according to the results of N-gain and the percentage, was better at the outcome comparing to the concept attainment model. Referring to the result of the t-test, it also indicated that there was a significant comparison between the Treffinger model and the concept attainment model towards academic achievement especially the cognitive domain showed by tobserved>tcritical.

Published: March 2020

Abstract
The purpose of this research was to compare the diameter of the fiber produced using the electrospining method and scaling law model. The electrospinning process is a simple technique in producing nanofibers from the incorporation of various polymers. The polymer material used is Poly (vinylpyrrolidone) (PVP) with Cellulose acetate (CA) solvent. Cellulose acetate (CA) solvents using different concentrations were 6% (PC 1), 10% (PC 2) and 17% (PC 3). The process parameters used electrospinning voltage is 10 kV, the needle tip to collector distance is 13 cm and flowrate used is 3.2 µL/hour. The product of nanofibers was morphologically characterized using a digital microscope and the fiber diameter size was predicted using a scaling law model. The scaling law model predicts electrical conductivity in PC 1, PC 2, PC 3 samples are 0.004298 S/m, 0.001289 S/m, and 0.000374 S/m respectively. The results of the logarithmic comparison of Q/K to the diameter of the nanofiber produce a linear graph pattern with a decrease in the value of K resulting in the diameter of the nanofiber-based on the results of experiments that have been carried out.

AbstractThis study aims to identify the creative thinking skills of vocational school students with Malay ethnicity in solving problems regarding Archimedes law. Creative thinking skill is skill that students must have in the 21st century. Therefore, this skill must be trained through the learning process. This research was conducted on 21 students of class X DPIB with 12 men, 9 women and 15 of them are ethnic Malay, the rest are settled migrants. This research is a case study research. The data obtained were analysed with Rasch Analysis Model (RAM). From the analysis results it was found that the ability of Malay students’ creative thinking was still low. The reliability person is weak and the reliability item is good. The tendency of respondent’s ability to work on problems is smaller than the level of difficulty of the questions. There are differences in the level of creative thinking ability of Malay ethnic and non-Malay ethnic students.
