image_folder = 'F:\kuliah\semester6\TA2\mencoba';
outfolder = 'F:\kuliah\semester6\TA2\mencoba\hasil';
if ~isdir(outfolder); mkdir(outfolder); end
load mri %I presume it has the variable map in it
fileinfo = dir(fullfile(image_folder, '*.jpg'));
filenames = fullfile({fileinfo.folder}, {fileinfo.name});
total_images = numel(filenames);
for n = 1 : total_images
thisfile = filenames{n};
[~, basename, ext] = fileparts(image_folder);
citra = imread(thisfile);
V = squeeze(citra);
fprintf('processing %s\n', basename);
citra3 = montage(reshape(V,size(citra)), map, 'Indices', 3);
outfile = fullfile(outfolder, [basename 'coba' ext]);
saveas(citra3, outfile);
end
A folder containing many images has been read, but only one output is stored. I have been helped by Mr.Walter Roberson, but I still can't solve the problem of how to save multiple images from the output of the matlab process.

You simply have to generate a sequence of unique filenames to save to. Something like this:
outfile = fullfile(outfolder, sprintf('%s-coba-%03d.%s',basename,n,ext]);
saveas(citra3, outfile);
That way you'll generate filenames of the type: basename-coba-001.ext - I replaced the whitespaces in the filename with '-', because I prefer to have dashes instead, you can switch back. The %03d is just to give you zero-padded numbers incrementing with your loop-variable n.

Think about your code. What are you doing and why? Have you read the documentation for the functions you are using?
If you read the latest error message: "Undefined function or variable 'n'." Can you see where you define n? What was that line doing? What was the reason you commented it?
If you have trouble with Matlab basics you may consider doing the Onramp tutorial (which is provided for free by Mathworks).
Also, feel free to put multiple things in 1 comment, instead of letting me merge your comments.
