Abstract

Cellulose had been isolated from rice husk waste and sawdust with chemical method through hydrolysis with HCl 2.5 N and bleaching process with  H2O23%.The yields were 13,45% and 22,75% (w/w) of cellulose from rice husk waste and sawdust, respectively. The chemical treatment caused partial removal of lignin and hemicellulose from raw material showed by FTIR spectrum.  Structure and morphology of cellulose from rice husk waste and sawdust were investigated using X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The XRD patterns showed cellulose structure converted from amorphous to crystalline form after bleaching process while SEM images showed that the isolated cellulose from rice husk waste had rougher surface than cellulose from sawdust. The SEM micrograph also showed that the isolated cellulose from rice husk was in the form of aggregates.

Abstract

The general puposes of experiencing math subject to elementary and middle school students are; first preparing the students to face the changing of real life through the thinking rehearsal based on the effective, effisien, honesty, critical, rationale, and logical way of thinking, and second, preparing the students to apply the mental principle of math in their daily life and as basic in learning other disciplines. Regarding to the importance of learning this subject, teacher of math should be able to create an effective teaching learning process to stimulate and to rise students enthusiasm in learning match. One of the strategy that can increase students desire in learning math is PAILKEM (Pembelajaran Aktif, Inovatif, Lingkungan, Kreatif, Efektif, dan Menarik). There is an interactive dialoque between teacher students and students-students, during teaching-learning process.This creates a condusive situation in wich students feel free to discuss their problems in learning math to their teachers and their classmates. At the end, through this strategy, students can increase their ability in learning and it is hoped that teaching learning process will be done in optimal achievement.

Abstract

The  purpose  of  this  research  is  to  know  whether  students’  understanding  of mathematics  concept  by  using  Inside-Outside  Circle  method  is  better  than  students’ understanding  of  mathematics  concept  by  using conventional  method  for  student  garade VIII of SMPN 11 Padang. The kind of this research is experimentalresearch, by using students in class VIII D and VIII E as samples which registered in 2011-2012  academic year. The instrument of this research is written test in essay form based on  the indicator of concept understanding.  Based on the data analysis to test the hypothesis, it is found that P-value 0.013  is lower than  α=0.05, it means that Hois rejected and H1is accepted. So, it can be  concluded  that  students’  understanding  of  mathematics  concept  by  using  InsideOutside Circle method is better than students’ understanding of mathematics concept  by using conventional method.Key Word: Lingkaran Dalam Lingkaran Luar, Pemahaman Konsep Matematis

Abstract

Education is proposed to cause humans to have good personality and characters. The implementation of character education needs whole understanding about the concept of character building and education. Building the students’ character is not an easy and simple task, but it needs some serious efforts which should be continuously done. Therefore, government has promoted curriculum based-character from 2010-2014, by which the character education is not only assigned to one of the subjects as Citizenship Education, but also to other subjects including mathematics. Mathematics is one of the subjects supporting the government program of character education, because some character values, as honesty, responsibility, care network, independence, and etc have been integrated in it. Thus, learning mathematics is not only focused on gaining cognitive purposes, but also on gaining affective and psychomotor purposes. In learning process, the teacher character so that the students can put him or her as the rule model. Key Word: Character Education

Abstract

The infortance of mathematics’ role indicates that the students have to learn mathematics seriously, and actively. So, they are able to understand the concept of math, reasoning and communication, and problem solving. The reasearcher found that students of class XI Social department SMAN 12 padang dit not understand concept of math well. It could be seen from the degree of completeness of mid semester 2008-2009 academic year, taht was only 53%.One of learning model that was applied to overcome this problem was cooperative learning type Group Investigation (GI). Investigation is a learning activity which gives a chance to students to improve their understanding through several activities and the result will be suitable with the students’ development.
