Abstract

The aims of research were to analize: (1) Student’s skill proccess science by using inquiry training learning model better than direct intruction learning model; (2) Student’s skill process science who had under average better than above average category in scientific knowledge; and (3) the interaction between learning model and the level of scientific knowledge in fluencing student’s skill process science. The research was quasi-experimental research. The population of this research is all of thenth grade students of SMAN 3 Gunungsitoli. The sample of this researchconsist of grade with was taken by cluster random sampling were X2 and X3 class.The research instrument consisted of skill process science essay test and criticalthinking skills test data be analysed by using Two–way ANAVA. Result of theresearch showed that kill of the student science process (1) between inquiry training and direct intruction, where inquiry training better than direct intruction, (2) between group of student in the group of the students scientific knowledgeupon and under of mean, where scientific knowledge upon of mean better then scientific knowledge under of mean, (3) no interaction between inquiry training and scientific knowledge increased skill of student science process.

Abstract

This research is aimed to know and describe the students Achievement using problem based learning and conventional learning about static fluid topic . This research employed a quasi experimental pretest and posttest with control design. The populations were 60 students grade Xl-science in SMAN 2 Lintongnihuta academic year 2015/2016. The samples consist of two classes, one class with 30 students as experiment class and one class as control class with 30 students, while the sampling technique used purposif sampling. Research instrument used essay test. The data obtained in the study were analyzed by the computer program Ms.Excel. From the research the pre-test average value of outcomes experiment class 26.66 and control class 27.83, after giving the treatment the post-test with the average value of outcomes experiment class 59.66 and control class 49.50. The result of t test Uunt = 3.158 while ttabie= 1.661. Because tc<>unl>ttabie(3.158> 1.661) so Ho rejected. The result showed that students achievement in experiment class had been treated with problem based learning model have significantly different from control class which had been treated with conventional learning. In addition, the improvement of PBL in experiment class was greater than in control class. This meant implementation problem based learning has a significant effect toward student achievement.

Abstract

ZnS nanoparticle has been syntesized from zinc asetat andthiorea 0.2 M using copresipitation method. The structure of the ZnSnanoparticle are wurtzite with hexagonal and blende (sphalerit) withcubic shape with average size of 39.56 nm. The elements of the ZnSmeasuring using EDS it was found that Zn has a mass of sebesar52.20% with disperse energy of 8.630 keV and S element of 18.92%with disperse energy of 2.307 keV.
