Abstract

Abstract The teaching and learning process will be more effective and efficient if supported by the right media. Research has been conducted to see the learning outcomes of students in class XI of SMA 14 by using cassette recording media as an alternative learning media in environmental chemistry material with the subject matter of the subject of environmental pollution. This research is a classroom action research (CAR) which is carried out in class XI students. Data collection techniques used are observation, tests and documentation. The data analysis technique is in the form of qualitative data and quantitative data. The results of data analysis show that classical completeness in the first cycle is 70%. While classical completeness in cycle II is 95%. This means that student learning outcomes from cycle I to cycle II increased by 25%. Based on the results of these studies it can be concluded that the application of cassette recordings as an alternative media can improve student learning outcomes in environmental chemistry subject matter of environmental pollution in Padang 14 High School. Keywords: Teaching Media, Cassette Records, Children's Learning Habits and Learning Outcomes and Environmental Pollution.

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

Vitamin C is one of the vitamins that the body needs to increase immunity in warding off all forms of disease. One of the fruits that contain vitamin C is srikaya fruit. Srikaya fruit is a plant belonging to the genus Annona originating from the tropics. Srikaya fruit is analyzed for its vitamin C content in order to increase the immunity of the community during the COVID-19 pandemic. The method used is a laboratory experiment with the iodometric method. The result is that srikaya fruit contains a fairly high amount of vitamin C, with the average vitamin C levels in the srikaya fruit sample being 2.58%, 2.503% and 2.66%, respectively, while the average vitamin C content in the srikaya fruit sample is 2.581%. And during this pandemic, we should consume a lot of food and fruit with vitamin C to increase the body's immunity, so that it can be developed to the next stage of further and more effective research.

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

The purpose of this study was to find out which student learning outcomes were better between using snowball throwing cooperative learning models assisted by power point media or using conventional learning models on hydrocarbon compound material in class XI MIPA SMA Negeri 1 Benai. The type of research used is a quasi experimental design with a posttest only group design. The sampling technique is cluster random sampling through drawing. Then it was found that the sample of class XI MIPA 4 studentas an experimental class and class XI MIPA 5 as a control class. The trial instrument used was content validity that was judged by 3 experts, item analysis (level of difficulty, differentiation, deseption effectiveness) and reliability of the questions processed by the help of ANATES. The test used was an objective written test of 20 questions. To test thenormality of the data used the Kolmogorov Smirnov test, the homogeneity test uses the Statistical Levene test and the hypothesis test uses the “t” test, namely the independent sample t test. The research hypothesis test showed that the value of sig. (1-tailed) was 0,000 < 0,05 then H0 was rejected. So that it can be concluded that student learning outcomes using cooperative learning models snowball throwing type assisted by power point media are better than student learning outcomes using conventional learning models.
