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

INFLUENCE OF CALCULATION TEMPERATURE TO HIDROTALSIT Mg / Al WHICH IS DISINTESTED THROUGH UNSECUAL METHOD OF PRESIPITATION Hasan Adidarma; Sri Handayani; Cahyorini Kusumawardani; Kun Sri Budiasih

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.
