        abstract = {Research on the application of ceramic filter membranes and humic acid 
adsorbents in reducing the concentration of remazol red dye and the COD value 
of batik liquid waste has been carried out. The purpose of this study was to reduce 
the concentration of remazol red dye and COD value of batik liquid waste using 
ceramic filter membranes and humic acid adsorbents. Ceramic filter membranes 
used are made from clay, silica sand and variations in the amount of wood
sawdust additions as much as 0, 1, 3, 5 and 7\%. Then porosity filter membranes 
are tested for porosity to find out the percentage of the total pore volume owned 
by the ceramic filter membrane. Determination of optimum pH of adsorption was 
studied at pH 1,2,3,4,5, and 6. Humic acid adsorbent was characterized by 
Fourier Transform Infrared Spectrophotometer (FTIR) to determine functional 
groups. Humic acid FTIR characterization results before adsorption of remazol 
red dyes showed the presence of O-H, C-H, C = O, C = C, and C-O groups. There 
is a shift in the wave number after the adsorption, that is, the O-H, C = O, and C?O groups, which indicate an interaction between humic acid and remazol red dye. 
The ceramic filter membrane with the composition of clay, silica sand and 1\% 
wood sawdust is the most optimum in reducing the color of remazol red to 86.68\% 
and reducing the COD value by 97.87\%. The pH optimization of remazol red dye
solution in the adsorption method using humic acid adsorbent occurred at pH 2 
and was able to reduce remazol red dyes by 69.94\% and a decrease in COD value 
of 96,35\%. Based on the results of the study, it can be concluded that the filtration 
method using ceramic filter membrane is more effective in reducing the 
concentration of remazol red dye and COD value in batik liquid waste compared 
to the adsorption method using humic acid.}
