Based on observations and interviews at SMAN 1 Rambatan, it was found that the teaching materials used by teachers were only textbooks and worksheets on material, formulas, and there were no practicum materials which were improved the 2013 curriculum. This caused the students have not found their own concepts. Therefore, this study aims to create a CTL based learning module to achieve valid HOTS, and practically can assist student in solving physics material, specifically for material harmonious vibration. This type of is research development or research with 4-D research models. which are donated : approved, developed, and disseminated. The CTL learning-based module for achieveing HOTS goals in physics learning designed about seven lessons, named : constructivism, asking questions, inquiry, learning communities, modeling, reflection, and authentic assessment which are studying LOT...

This research is quasi-experimental research. As the population of this study were all students of class X consists of nine classes taken at random, taken two classes will be assigned as the control class and experimental class. The sampling technique using simple random sampling when members of the population considered to be homogeneous, measures of sampling there are four phases: (1) collecting the value of daily tests of students, (2) test of normality (3) to test the homogeneity (4) analyzing the variation, Results of the study were taken from 33.33% yield cognitive learning, 33.33% affective domain of learning outcomes, 33.33% psychomotor learning outcomes. Obtained an average of learning outcomes experimental class and control class 68.49 73.19 hypothesis testing performed using t-test...

As a result, it is necessary to develop a constructivism-based electronic physics module. The objective of this research is to know the validity of constructivism-based electronic physics module for 1st student in Senior high school. This research is research and development research. Feasibility tests of the electronic module are carried out through the validation. Validation was carried out by three validators. Based on validation, it showed that constructivism-based electronic physics module that was developed is very valid with a percentage of 89.08%.AbstrakKeterbatasan pada modul cetak serta kurangnya ketersediaan media pembelajaran yang berbasis teknologi menyebabkan kurangnya motivasi siswa dalam mempelajari fisika.

The performance of such devices is strongly depending on the nanostructures of the thin films used. In this paper reports the effect of growth temperature during synthesis of one-dimensional (1-D) anatase ZnO nanorod arrays through hydrothermal process facing their structure, morphology, and optical properties. The ZnO nanorod was first synthesized use the solution concentration and time fixed at 0.04M and 1 hour. The growth temperature were varied from 70, 80, 90 and 100 °C. The effect of growth temperature on the structural, morphology, and optical absorption of ZnO nanorod were studied by using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and UV–vis spectroscopy. The regularity, diameters, heights, and surface densities of the ZnO nanorods were increased with the growth temperature.The optimum results of FESEM characterizations showed tha...

The graphite oxide was first synthesized by using modified Hummers method and spin coated on quartz substrate to form graphene oxide film. X-ray diffraction, field emission scanning electron microscopy, UV–Vis spectroscopy and four point probe measurement were used to characterize the resultant multilayer graphene. The transmittance and sheet resistance decreased with the thermal reduction temperature. The lowest sheet resistance of 91.6 ± 0.3 kΩ/sq was obtained at temperature of 500 °C, showing almost 100 times improvement compared to that prepared at 200 °C.
