Orb spider

Thanks for genus info. How about Nephilia pilipes? This species also have been found in Indonesia and I think has the most similar morphology.

Well with further research, I still cannot identify the specific species but it is definitely an orb from the genus Nephilia and most likely a female.

It looks like a giant wood spider with its size and its legs but not it's specific markings. That is from the Nephila genus.... Try that for your research. If it is that they are very large and very common to Indonesia and the oldest living genus of spider on record.

Fantastic spotting!

nice one !!
