Abstract

Research on the manufacture of composite particle board based on natural fiber: coconut fiber (SSK) and banana fiber (SBP) by using PVAc matrix has been conducted. The purpose of this research is to get the physical and mechanical value of standard on composite board based on SNI03-2105-2006The research method is by taking the comparison of banana fiber reinforcing material (SBP) and coco fiber (SSK) in the form of particle size with composition ie (a) SBP 0%: SKK 100% (b) SBP 50%: SKK 50%, (c) SBP 80%: SSK 20, (d) SBP 60%: SSK 40%, (e) SBP 40%: SSK 60%, (f) SBP 20%: SKK 80%, and (g) SBP 100%: SSK 0%.All composite boards consist of 70 % Matrix and 30% fiber. The result of physical properties for density (ρ) ranges from 0.54 gr / cm3 - 0.75 gr / cm3 and for water content (KA) ranges from 10.5% - 13.9%.As for the mechanical properties of the value of modulus rupture (MOR) ranged between 3483.44 kgf / cm2 - 7472,30 kgf / cm2 and elastic modulus value (MOE) ranged between 15981.23 kgf / cm2 - 27243,74 kgf / cm2. Based on the analysis of tredline graphs, both for physical and mechanical properties, it turns out for each composition of natural fibers to give different values.This means that the composition of the SSK-SBP mixture has an influence on the physical properties as well as the mechanical properties of the composite board. The quality of natural fiber-based composite board (SSK and SBP) both physical and mechanical properties have been in accordance with the standard reference SNI 03-02105-2006.

Abstract

Al-Zn doped SnO2 (Sn1-2xAlxZnxO2) film has been growth using the sol-gel dip coating technique. The basic materials used in this study were water, C2H5OH, SnCl2.2H2O, AlCl3 and ZnCl2 with 99% purity (merck) with doping concentration variation x = 0.000, 0.005, 0.025, and 0.050. Glass substrate with size 2.54 mm x 76.2 mm x 1 mm cleaned with detergent, soaked in 30% HCl solution For 1 day and dried at 100°C. The process of making a SnO2 sol is done by mixing the precursor with various concentrations with water and stirring using a magnetic stirrer for 30 minutes at a temperature of 80 ° C. The next step by adding ethanol, stirring at 80 ° C. for 2 hours to obtain 0.4 M sol solution The deposition of SnO2 film was carried out using a dip coater with a whitdrawl speed 12 cm/min and then heated for nucleation and grown using an electric furnace at 600 ° C for 30 minutes. This step is repeated as much as 5 repetitions to get the SnO2 film by doing Al-Zn.

Abstract

This study aims to develop and produce a physics history textbook based on higher order thinking skills (HOTS). This research was a development research which consists of four stages, namely: the determination stage, design, development, and dissemination. The success of the indicators of this research were seen from the feasibility of the developed textbooks. Physics history textbook based on higher order thinking skills was categorized as good and suitable for use, in terms of content, presentation, and language feasibility. Meanwhile, in terms of textbook effectiveness, it was measured by the impact of increasing students' higher order thinking skills as seen from the increase in N-gain.  The student's high-order thinking skills had increased with N gain 0.4 (moderate category). This shows that the textbooks that have been developed are feasible and effective in terms of the ability to increase higher-order thinking skills (HOTS).

Abstract

The purpose of this research is to develop APKEMIT as learning tool for high school physics on temperature and heat concepts. This study used Borg & Gall approach on R & D which includes the step of development, pilot testing, and final testing. In the development stage, five APKEMIT models are produced: PKTSB, PW, PPSTUB, PK, and AB. Pilot testing stage is divided into two phase, limited testing and large scale testing. The first limited testing carried out on 6 eleventh grade science students in SMA 3 Mataram. The second phase carried on 2 groups (12 students) of accelerated tenth graders in SMA Negeri 1 Woha. Large-scale trials given to 8 groups (46 students) of tenth graders in SMA Negeri 3 Mataram. Pilot testing shows that APKEMIT is very good and ready to be used in learning activity. APKEMIT final testing stage is the stage to determine the effect of APKEMIT on the improvement of learning outcomes, which is determined by the Gain Score. Analysis shows that the gain of each model is: PKTSB Score of 0.50 (medium), PW of 0.15 (low), PPSTUB of 0.40 (medium), PK at 12:27 (low), AB of 0.34 (medium) and overall Gain Score at 0:36 (medium). This development received good response from the students with score 80.8% and according to observers, learning process has been going very well. The result of research  and validation of test show that the developed APKEMIT become as references in subject temperature and heats concepts.

Abstract

This study aims to determine the effect of cooperative learning through problem posing approach to the mastery of concepts of students in terms of prior knowledge. The method used is a quasi-experimental method with 2x2 factorial study design. The study population was 163 students of class XI SMKN 9 Mataram scattered in 5 classes. These samples included 55 students, divided into two classes by cluster of random sampling technique. The research instrument is a test mastery of concepts and problem solving skills test given at the beginning and end of the study. The data was analyzed by Manova two ways. The results showed that (1) students learn to use cooperative learning model with problem posing approach was significantly different in the aspect of mastery of concepts than students who study with learning cooperative model only, (2) students who have high prior knowledge different significantly in aspects of mastery of concept compared students who have low prior knowledge, (3) there was an interaction effect between learning model with prior knowledge of the mastery of concepts students. Keywors: Cooperative Learning Model, Problem Posing, Prior Knowledge, Concepts Mastery
