Abstract

The investigation of bimetallic CuPt Nanoparticles (CuPt NPs) with average diameters in the 196.7±98 nm range have been prepared by the Liquid phase deposition methods and synthesized directly on an indium tin oxide (ITO) substrate. CuPt NPs with  high surface defect grown on (ITO) surface were prepared via a simple immersion of the substrate into a solution contains 1 mM Potassium Hexachloro Platinate (K2PtCl6), 0.2 mM Anhydrous Copper (II) Sulfate (CuSO4) anhydrous, 0.01 M Sodium dodecyl sulfate (SDS) and 10 mM Formic acid for 4 h at room temperature. The modification of Cu2+ ion precursor play a role to determine the nanoparticles geometry obtained. The simultaneous reduction of metal ions leads to either a surface enriched with one component or an alloy type of structure depending on the bimetal composition. The bimetallic CuPt NPs dispersions are characterized by FESEM, EDX Mapping, XRD, HRTEM and XPS analysis.Key words: CuPt, Liquid phase deposition, Bimetallic CuPt NPs

Abstract

This study aims to see the effect of the gallery walk method application to the attitudes and activeness of the students. The research data was obtained through quasi-experimental research by using randomized subjects posttest only controlled group design. This research was conducted at VIII grade students of MTsS Darussalam Sitiung 1 Islamic Boarding School Dharmasraya Regency which consisted of 2 classes with a population of 50 students. Samples were selected by simple total sampling technique, where the experimental and the controlled class were selected by lotting method. Data collection was carried out using observation and data analysis techniques through statistical tests consisting of normality, homogeneity and hypothesis tests with a significance level of 5%. Data from the hypothesis using the t test shows that the tcounted for the formation of attitudes, and activeness is 3.21 and 2.16, respectively with v = 48. Based on these values it is known that tcounted> ttable for the attitudes and activeness of students, namely (3.21> 1.677), and ( 2.16> 1,677) at the 5% significance level. Thus the hypothesis Ho is rejected and H1 is accepted, where the formation of the attitudes and activeness of students using the gallery walk method is better than using conventional learning with a certainty of 95%.

Abstract

This study aims to produce free fall practicum tools by utilizing phototransistor sensors to record the travel time of objects that fall from the starting point to the end point. Dealing with free falling equipment (GJB), equipment in schools is generally still very simple that is using a stopwatch. This type of research is a research and development using 4-d model (define, design, develop and disseminate), which is limited to the stage of development to practicalization activities. Data were collected through validation and responses toward  administered questionnaires.  Data analysis were conducted by analyzing validation sheet and quantitative response questionnaire by finding percentage of each item on the validation sheet. Then the data validation results are analyzed by descriptive technique to describe the quality of the developed product. The result of calibration of free fall practicum by using phototransistor sensor at 40 cm, 50 cm, and 70 cm distance obtained the average travel time of each object is 0.28 s, 0.32 s, and 0.37 s. These results indicate that the practicum tool has been calibrated. Validation of practicum tool is 72,39% and validation of questionnaire response of practican is 75%, indicating tool categorized valid. Furthermore, this tool is tested in class X.MIA and XI.MIA MAN 3 Payakumbuh which consisted 23 students in the science laboratory of MAN 3 Payakumbuh with the questionnaire response practicality are 87.75% and 84.41% respectively which are categorized very practical.
