This study aims to design implementation strategies of DCT in the Basic Inorganic Chemistry course, develop an appropriate course to increase students’ active participation, and develop an evaluation system capable of providing an integrated assessment (both the learning process and outcomes) in the course. This study was conducted in two cycles for one semester during the academic year of 2008/2009. The implementation applied the principles of classroom action research consisting of four stages, i.e. planning, action implementation, observation, and reflection. The data were analyzed by grouping them into categories. The findings were as follows. Qualitatively, the classroom observations showed an increasing active participation of students, both in making the DCT and in conducting discussions in English. Quantitatively, the results of the observations on the learning activities showed an average value of 4 (scale 1-5) for several aspects of DCT.

Catalyst are divided into two kinds, homogeneous and heterogeneous catalysts. The catalys tthat constantly developed isa heterogeneous catalyst because could be separated easily and reuseable. The purpose of this research were synthesis and characterization of hydrotalcite Mg/Al as a heterogeneous catalyst which can be use din the aldol condensation reaction. Synthesis hydrotalcite was conducted by hydrothermal coprecipitation method. Synthesis performed with variations mol Mg/Alat a temperature hydrothermal 1000C for 15 hours. Hydrotalcite as a heterogeneouscatalyst preparation was done by calcinationat 4000C. Characterization of synthesized hydrotalcyte was performed by FTIR to identified functional group and XRD analysis to characteriz edits structure. The results showed that the optimum conditions for the synthesized hydrotalcite was obtained atmole ratio Mg/Al3:1.

The purpose of this research is to obtain a method of color standardization which is a consistent assessment of the color formed by secang natural dye, so it can be used as a reference color of natural dyes of batik.Standardization steps of natural dyes included taxonomic examination, preparation of secang dye by extraction, standardization process by spectroscopic measurement, with “rapid” dye as standard, application on batik process including batik pattern making and wax application on batik and batik coloring process with secang dye. Data was analized by absorbance vs wavelength obtained from red color formed by secang dye. The results showed that the maximum absorption wavelength of the standard red color was obtained at 450.20 nm. This value is used as the standard red color measurement

This research aims to determine the effect of calcination temperature variation from 200°C to 500°C on the Mg/Al hydrotalcite structure. Mg/Al hydrotalcite has been synthesized via a low supersarturated precipitation method with hydrothermal treatment, using Mg(NO3 )2 .6H2 O and Al(NO3 )3 .9H2 O as the raw materials, and base solution of NaOH and Na2 CO3 as the precipitators. Mg/Al hydrotalcite compound synthesized before and after calcination were characterized using fourier transform infrared (FTIR) and X-ray diffractometer (XRD). The results of FTIR and XRD data analysis showed that the calcination of hydrotalcite of Mg/Al at 200o C did not changed the structure of hydrotalcite compounds, calcination at temperatures 300-400o C showed that structure of hydrotalcite compound starts to change form a mixture of magnesium oxide and aluminum, and calcination at 500°C showed that the crystal structure of Mg/Al hydrotalcite has broken to form a mixture of metal oxides, namely MgO (phericlase) with a little mixture of aluminum oxide in the form of θ-Al2O3 and γ-Al2O3.

This research aimed to determine the efficiency of immobilization of Cr(VI) on the rice husk ash based geopolymer with a TCLP (Toxicity Characteristic Leaching Procedure) study. The TCLP was refer to the standard method from Japan Environmental Agency. There were three variables used i.e., concentration of Cr(VI) impregnated, particles size, and the kind of leaching water. Determination of immobilization efficiency was done by calculate the concentration of Cr(VI) in the leachate water after the leaching processes. Quantitative measurement of the chromium was done by Uv-Vis spectrometer with biphenyl carbazid reagent. Immobilization of Cr(VI) on the rice husk ash based geopolymer was establish until 25 ppm Cr impregnated. The efficiency of the immobilization can reach 90% - almost 100% depend on the variable of leaching processes. Keywords: eficiency, immobilization, geopolimer, rice husk ash, TCLP study

This research aims to synthesize Mg/Al hydrotalcite with mole ratio variations of Mg/Al precursor through low supersaturated precipitation method. Mg/Al hydrotalcite was synthesized with Mg/Al mole ratio variation of 1:1, 2:1, 3:1, and 4:1. Mg/Al hydrotalcite was synthesized using NaOH and Na2CO3 base solutions. The mixture of precursor was stirred for 2 hours then treated by hydrothermal at 100 °C for 4 hours. Results of the synthesis Mg/Al hydrotalcite with mole ratio variations is a white powder. The formation of the structure of Mg/Al hydrotalcite showed by certain peaks in the FTIR spectra and XRD diffractogram.The results of data analysisshowed that variation of mole ratio Mg/Alcauses a shift of peak in the XRD diffractogram shifted towards the left along with a comparative increase in mole ratio Mg/Al, but the main functional groups on the compound Mg/Al hydrotalcite increasingly formed with better.
