I just stored my data from matlab to excel file using xlswrite , looks like this..but i have no idea to query column name based on cell values..
for example if my threshold is = 1.6155 then it will retrieve column name such as = "Merah Ma , Kuning, Hijau"
return the column name values where cell values greater than 1.6155

You can accomplish this with logical indexing. See below for an example:
d = {'Putih','Abu-abu','Hitam'; 0.014149,0.04175,0.081601};
thresh = 0.02;
idx = [d{2,:}] > thresh;
col_names = {d{1,idx}};
