Just looked at #1 first - this is copy/pasted. It isn't the worst sort of plagiarism because the author did link to the Indonesian wikipedia source at the bottom, but even providing a source when all you have done is use Google Translate to translate the Indonesian language version of a Wikipedia article and pasted it in here is still not cool. Adding an intro paragraph doesn't make it original.
There are a few clues here that this was copy/pasted - I was nearly 100% certain it had been before I even got to the bottom of the post and saw the link the author left. Check out all the strange line breaks that would never have occurred if someone was typing this on Steemit or typing in a word processor (marked with pink "x"). No one hits a hard return in the middle of typing a sentence. This sort of thing only occurs when copy/pasting from websites.
