Telah dilakukan penelitian tentang pengembangan pembuatan papan partikel komposit yang bertujuan untuk memenuhi kebutuhan kayu yang semakin meningkat. Bahan baku papan komposit yang berlignoselulosa misalnya Serbuk tempurung Kelapa YANG didapat dari Kampung Lalang Medan. Pada penelitian ini telah dievaluasi sifat fisis dari bahan tersebut diantaranya uji fisis yang dilakukan meliputi: Kerapatan, Kadar Air dan Pengembangan Tebal dengan perlakuan komposisi polipropilen dan serbuk tempuru yang ng kelapa bervariasi yaitu: 30 : 70, 40 : 60, 50 : 50, 60 : 40, 70 : 30 dengan menggunakan standar SNI 03 – 2105 – 2006. Dari hasil penelitian ditunjukkan bahwa nilai sifat fisis papan partikel komposit Polipropilena dan serbuk tempurung kelapa yang dihasilkan memenuhi standar SNI 03 – 2105 – 2006. Kata Kunci : Papan Partikel, Plastik Daur Ulang, Serbuk Tempurung Kelapa, sifat fisis

This research aims at describe the cognitive abilities of physics through the use of learning-based LKS Natural (JAS) in the subject matter and the temperature of the heat in SMA N 2 XIII Koto Kampar and know the difference between the cognitive abilities of students studying physics using worksheets based natural learning (JAS ) with students who learn using conventional LKS. This research was conducted in SMA N 2 XIII Koto Kampar in February to June 2015. The subjects were class X IPA 1 and X IPA 2 totaling 49 students who have been tested for normality and homogeneity of both classes. The design of this study was preexperimental design with Intact-Group Comparison. The research instrument used is the achievement test of cognitive ability. Data collection techniques is the provision of learning outcomes of cognitive ability tests consist of 20 multiple choice items. Data were analyzed through descriptive and inferential analysis. Descriptive analysis of the results obtained by the average absorption using LKS JAS class higher than the class that uses conventional LKS both categories, the effectiveness of otherwise effective learning, mastery learning students in classical declared complete mastery of the subject matter and declared incomplete. Inferential analysis through the calculation of statistical values t test manually and through SPSS 17 obtained t count = 1.282, while t table = 2.012. Based on the criteria of hypothesis testing t count <t table (1.282 <2.012), so there is no significant difference between Cognitive Ability Physics students learn to use worksheets based natural learning (JAS) with students who learn using conventional LKS.
