Abstract

 ABSTRACTThis research was carried out due to the student’s low learning achievement in mathematics in class VIII of SMPN 3 Bonjol. This research was aimed at revealing whether the mathematics conceptual understanding of the student’s taught by using TTW cooperative learning was better than that of student’s taught by using conventional learning. This was an experimental research which used random toward the subject design. Based on the result of data analysis it was found that the two sample classes were normally distributed and homogenous. Furthermore, the result of t-test indicated that the value of tcalculated (7,23) was higher than ttable (1,67) in which α was 0,05. This result showed that the mathematics conceptual understanding of the students taught by using TTW cooperative learning was better than that of student’s taught by using conventional learning in class VIII SMPN 3 Bonjol registered in academic year 2013/2014.

Abstract

This research was backgrounded by students understanding on mathematic concepts was low. This research was aimed to see what is the students understanding on mathematic concept by using Sucker Ball game better than the students understanding on mathematic concept by using conventional learning at Eighth grade students of SMPN 33 Padang academic year 2013/2014. This study was experimental research by random selecting group of sample. The technique of data nalysis used t-test by using MINITAB. Refering to the data analysis that had been clone it was found P-value = 0,042 was lower than α = 0,05. It can be summarized that the student understanding on mathematic concept using Sucker Ball game better than the student understanding on mathematic concept using conventional learning.

Abstract

ABSTRACT This research was designed for revealing whether the mathematic conceptual understanding of the students taught by using Snowball Thorowing active learning model was better than that of students taught by using conventional learning. This was an experimental research. The Population of this research was the students in class IX of  SMPN 17 Padang. In collecting the data, an essay post-test that consisted of six items on the conceptual understanding was administered to the sample classes. The data collected was analyzed by using normality test, homogenity test and t-test. Based on the result of data analysis, it was found that the average score of the students in the experrimental class was 83,04 and in the control class was 69,41. This result had indicated that the mathematics conceptual understanding of the students taught by using Snowball Thorowing active learning model was better than that of students taught by using conventional learning in class IX of  SM N 17 Padang.

Abstract

ABSTRACTThis research was based on the students’ low understanding of mathematical concept. This resulted in the students’ understanding of mathematical concept embedded optimally yet one good alternative to overcome these problems in mathematics learning strategies used The Power Of Two. This study aims to determine whether students understanding of mathematical concept by using active learning strategies The Power Of Two with quiz was better than the students understanding of mathematical concept using conventional learning in class VII SMPN 5 Padang. The design used was random against subject. With population of all VII grade students SMPN 5 Padang. Sample were taken at random. VII4 classroom experiments and VII5 selected as the control class. Research instruments are quizzed and final test in the form of an essay. From the analysis of test data and the understanding of concept normally distributed homogeneously. Based on the analysis result, the average student learning outcomes experimental class 98.42 higher than the control class is 82.81. From the hypothesis done t table obtained was less than the calculed. So it can be concluded that the students understanding of mathematical concept by using active learning strategies The Power Of Two with Quiz was better than the students understanding of mathematical concept using conventional in class VII SMPN 5 Padang.

Abstract

There is a value of Riemann integral from a function that cannot becalculated. In this case, approximate method can be used to interpret the value.One of the approximate method of integral Riemann is tangent line method that isa compound method between the sum of Riemann and trapezoid method. Thetangent line method uses the tangent line approach. In this writing, the topicdiscussed is the tangent line method in deciding the approximacy of Riemannintegral of a function.

Abstract

The drawing a graph of the equation is positioned by it as the material prerequisites that must be mastered to solve the problems on the subject. However, based on teaching experience for many students who indicated not been able to describe the graph equation graph. The study aims to describe the students' ability to draw graphs of quadratic and line equations,of first-year students who took Calculus subject at Mathematics Department, Padang, Indonesia. The data source was selected purposive and snowball sampling. Sources of data in this study were 70 first year students in Differential Calculus subject class. Research shows that understanding of students to graph a quadratic equation is still very low, they often mixed graphs of quadratic equations and linear equations, and understanding of students to graph line equation is still very low, especially on understanding the line y = k and x = k, k is a number

Abstract

Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan keterampilan teknik membatik dan strategi mempertahankan warna pada produk Batik Kopi di Nagari Pariangan, Kabupaten Tanah Datar, Sumatera Barat. Batik Kopi Pariangan memiliki keunikan pada bahan pewarna alami yang digunakan, yakni ampas kopi. Namun, perajin masih mengalami kesulitan pada proses membatik dan mempertahankan warna produk batik yang dihasilkan. Kegiatan pelatihan ini dilakukan melalui metode ceramah, demonstrasi, dan praktik langsung, dengan materi meliputi teknik dasar membatik, proses pewarnaan dengan bahan alami, serta teknik fiksasi warna. Hasil kegiatan menunjukkan peningkatan pemahaman dan keterampilan membatik serta strategi mempertahankan warna batik alami para peserta pelatihan. Kegiatan ini diharapkan dapat memperkuat potensi ekonomi kreatif berbasis budaya lokal di Nagari Pariangan.
