Abstract

This research aims to determine the effect of inquiry training learning model using PhET simulation media to student learning outcomes on static fluid subject matter. This research is quasi-experimental design with two control group pretest-posttest. With random cluster sampling technique by taking two classes of seventh grade is class X MIA-1 as the experimental class and class X MIA-5 as the control class with each numbered 32 people. The research instruments used in the form of test results in cognitive learning form description consists of 8 questions that have been validated and observation sheet to assess the activities. The result showed an average value 34.9 pretest experimental class and control class pretest 33.1. After the treatment si given experimental class with inquiry training learning model using PhET simulation media dan control class with conventional learning the data obtained with the posttest average yield experimental class dan control class was 68,5 and 61,1. Development activity of experimental class gained an average categorized as very active, and control group gained an average growth of activity in the category of active. Based on the results of hypothesis testing using different test (t-test) obtained the influence of inquiry training learning model using PhET simulation media on student learning outcomes in a static fluid material in the second half of class X SMA Negeri 1 Raya.

Abstract

SINTESIS NANO ZEOLIT ALAM MENGGUNAKAN METODE BALL MILLING. Telah disintesis nanozeolit alam Pahae dengan metode ball milling. Penelitian ini dilakukan untuk meningkatkan nilai jual sumber daya alam Sumatera Utara khususnya zeolit. Zeolit digerus sampai halus, lalu diayak dengan ukuran 200 mesh. Zeolit kemudian diaktivasi secara kimia dengan menggunakan HCl untuk membersihkan zeolit dari pengotor, dan secara fisis dengan kalsinasi pada suhu 600 oCselama 2 jam untuk mengurangi kadar air. Selanjutnya, serbuk zeolit yang sudah diaktivasi tersebut dimasukkan ke dalamball miling dan diaduk selama 10 jam untuk mendapatkan serbuk nanozeolit. Hasil X-Ray Diffraction (XRD) menunjukkan dua fasa dominan yaitu calsium aluminium silicate hydrate (CaAl2Si10O24.7 H2O) dan aluminium oxide (Al2O3). Dengan persamaan Scherer diperoleh ukuran kristal rata-rata zeolit adalah 74 nm. Hasil X-Ray Fluorescence (XRF)menunjukkan kandungan zeolit alam Pahae terdiri dari senyawa Na2O (1,03%), MgO (0,82%), Al2O3 (17,29%), SiO2 (71,06), K2O (4,63%), CaO (1,92%), TiO2 (0,51%) dan Fe2O3 (2,75%).
