Abstract

Students have difficulties in relating the chemistry phenomena they learned and the life around them. It is necessary to have teaching aids which can help them to relate between chemistry with the phenomena occurred in everyday life, which is chemistry?s teaching aids based on local wisdom. There are 3 teaching aids which used in chemistry teaching and learning, i.e. clay molymod, electrolyte tester, electroplating tool. The chemistry teaching aids was reviewed by media experts, material experts, and also reviewers. The reviewers? assessment showed that all of the teaching aids have a very good quality. Based on the response from Senior High School? students, they all agree that the teaching learning process using the teaching aids could improve their learning motivations.

Abstract

In the chemistry teaching and learning, Self-Regulated Learning (SRL) plays an important role in students? academic motivation and also academic achievement. An innovation in chemistry teaching and learning, such as applying of Multimedia Based Learning (MBL), could increase the students? SRL. The aims of this research were (1) to determine whether there is a difference SRL of high school students who applying MBL in chemistry teaching learning and students does not apply to the MBL, and (2) to determine whether there is an increased SRL high school students before and after applying MBL in chemistry teaching learning. The experiment was conducted in class XI SMA 1 Sleman to take Thermochemical matter. Researchers create a medium for these materials and continued with expert judgment of the media. Data SRL students were measured using validated questionnaires. Data analysis was performed using SPSS. The results showed that (1) there was no significant difference in SRL of students who participating in chemistry teaching learning by applying MBL and student who does not, which showed that the probability value of 0.711 or probability value> 0.05; (2) there are significant differences in SRL of students before and after participating in chemistry teaching learning which applying MBL, which is seen from the results of paired samples t-test, the price of p (0,000) <0.05.

Abstract

In recent years, the uses of Multimedia Based Learning (MBL) in classroom instruction increased widely. Overall, this implementation aims to improve students’ motivation and also their learning outcomes. This study was answering the effect of MBL toward students’ Self-Regulated Learning (SRL) in chemistry teaching and learning. The experiment was conducted in class XI of senior high school in Yogyakarta. Researchers create some computer based media for chemistry materials and continued with expert judgement of the media. Students’ data SRL were measured using validated questionnaire. The questionnaire consists of three components, i.e. metacognitive, motivation and behavior. The results showed that there was significant differences in SRL of students before and after participating in chemistry teaching and learning which applying MBL.

Abstract

Nowdays, Rasch model analysis is used widely in social research, moreover in educational research. In this research, Rasch model is used to determine the validation and the reliability of systemic multiple choices question in chemistry teaching and learning. There were 30 multiple choices question with systemic approach for high school student class XI. In this research, a 164 student as the subject of the research. The data was collecting during March ? April 2015. The data was analysis using Winsteps application with Rasch model. The reseach shows that 29 question of 30 questions was valid through Rasch model analysis. The reliability of systemic multiple choices question was 0.93, which is very good chategory.

Abstract

Purification of silica sand volcanic Mount Merapi has been done, for raw material photovoltaic. Leaching purification process is done using aqua regia solution, H2SO4, and HCl. Purification of silica sand of Mount Merapi as a raw material photovoltaic assumes that photovoltaic technologies that utilize solar energy is quite affordable, do not run out, and clean so that it will provide long term benefits are substantial. Stage purification process through grinding up to size 60 mesh, iron using magnetic separation, leaching of acid and alkaline leaching. Characterization of the samples using XRD and XRF. The result showed that Mount Merapi volcanic sand containing silica is high at 48-50%. XRD characterization results indicate that the silica in sand samples well as silicon dioxide or mineral has amorphous structure. Among aqua regia, H2SO4 and HCl leaching that has the ability to nicest namely the concentration of concentrated HCl and purified silica has a purity of 59%. Keywords: purification, silica, volcano sand

Abstract

The aim of this research was to determine the effect of pH on the adsorption of micronu- trients of Ca 2+  and K . by silica from lapindo mud. Data were collected by the adsorption experiments, on which 3 grams of silica separated from Lapindo mudwere dissolved in 300 mL of 0.0001 or 0.001 M Ca + 2+ or K ., and stirred for 2 hours. The pH of suspension was varied and left for equilibrate for 2 hours, and a sample was taken and measured for free concentration of K + + .cation  using Flame Atomic Emission Spectroscopy and of Ca  using Atomic Absorption Spectroscopy (AAS). The pH ranges were from 3 to 10. Temperature o  30 C and contact time of 2 hours were maintained. The research showed that both cations were adsorbed in sigmoid curve, increased with increasing pH values. In entire ranges of observed pH, the percentage of cations adsorbed by silica was not different signi? cantly. The adsorbent of silica formed silanol (SiOH) in water. The ?OH groups of silica were protonated forming SiOH o at lower pH and deprotonated forming SiO¯ at higher pH. Wether Ca 2+  or K + 2 + . cations were bound to silica surfacesvia cation exchange reactions, on which Ca2+ or K + . exchanged H of SiOH using one charge of the cations, forming [SiO(CaO)] for Ca 2+ , and [SiO-K] for K
