Abstract

Atomic Theory was one of learning materials delivered by discussion method. Discussion method was not make students more active in the learning process that caused student had low Minimum Completeness Criteria (KKM). One of learning strategies that could improve student activity was Teams Games Tournament (TGT) learning model type. This study aims to reveal the application of TGT learning model could increase percentage of student KKM in atomic theory in class XI IPA Development High School Padang. This type of research is an experiment by comparing the percentage of learning completeness with discussion method and with TGT. The population of this study was all students of class XI IPA Development High School Padang in the 2011/2012 academic year and the research sample was class XI IPA as an experimental class. Learning completeness by using TGT was 51.2% higher than discussion method that has 33.3% learning completeness. Therefore, there was an increase of learning completeness by 17.9% TGT. It means that learning chemistry using the Teams Games Tournament could increase the percentage of students' Minimum completeness criteria (KKM) on the atomic theory in class XI Padang Development High School.

Abstract

The identification of heavy metals Hg, Pb and Cd in the Batang Kuantan River, Kuantan Singingi Regency has been carried out successfully. Heavy metals are measured not only from their heavy metal content such as Hg, Pb and Cd but also from the pH level of the river flow itself. The research location is at the Batang Kuantan River, which is measured from 3 points. Changes in Data Observed / Measured are the quality levels of heavy metals in the waters. The research model used includes field research using survey and laboratory methods. The research design was analyzed using the Atomic Absorption Spectometer (AAS). The water sample was given HNO3 until it was acidic and filtered so that there was no sedimentation, then analyzed by AAS. Heavy metal analysis result data technique is compared with quality standard of government regulation no 82 of 2001 regarding water pollution control and water quality management. Pb did not have a problem because the levels were not found. Whereas for Cu and Cd in the category of concentration threshold for reasonableness, which ranged from 0.158-0.1598 ppm and 0.0233-0.2769 ppm.

Abstract

Limbah cangkang bekicot (Achatina fulica) memiliki potensi untuk dikembangkan sebagai sumber Kalsium Oksida (CaO). Limbah cangkang bekicot (Achatina fulica) memiliki kandungan mineral kalsium karbonat (CaCO3) yang tinggi. CaCO3 dapat didekomposisi menjadi CaO pada pemanasan suhu tinggi. Dalam penelitian ini, CaO disintesis dari Limbah cangkang bekicot (Achatina fulica) dikalsinasi 900 °C selama 10 jam (LCB-900-10) dan kemudian CaO yang dihasilkan dari proses kalsinasi dikarakterisasi menggunakan X-Ray Diffraction (XRD) dan XRay Fluorocense (XRF). Dari hasil difraktogram XRD senyawa CaO dari LCB-900-10 terdapat puncak lime yang berturut-turut beserta nilai intensitas relatif yang cukup besar di antaranya adalah pada 2θ = 32,1767°(37,9%); 37,3224°(100%); 53,8253°(55,42%); 64,1206° (15,76%); 67,3433° (16,32%); 79,6249° (5,08%); 84,7873° (0,22%); 88,4925° (5,35%); 91,4306° (14,88%), dengan kandungan CaO dilihat dari karakterisasi menggunakan XRF sebesar 98,629%.Limbah cangkang bekicot (Achatina fulica) memiliki potensi untuk dikembangkan sebagai sumber Kalsium Oksida (CaO).

Abstract

This study aims to determine student learning outcomes in Hydrocarbons material in class XI MIPA SMA Negeri 1 Cerenti. This research as a quantitative research type of quasi-experimental designwith posttets-only control design experimental design. The sample in this study were students of class XI MIPA 4 as an experimental class and class XI MIPA 1 as a control class. The sampling technique was cluster random sampling. This study used the Kolmogorov-Smirnov test. In this study usung the “t” test that is independent sample t-test. Based on the results o the final hypothesis test which was analyzed using thee independent sample test, the significance value (2-tailed) was obtained is 0,000<0,05. Because thi study uses 1-tailed, the significance value is 2-tailed = 0,000<0,05 so that H0 is rejected. The final test results obtained Sig (1-tailed) is 0,000 < 0,05 which mean H0 was rejected. It can be concluded that the learning outcomes of chemistry using the Jigsaw learning model was better which do conventional learning.
