I've heard that the parliamentary treshold is 2%.

However, it doesn't seem to make sense to me. There are around 500 people in DPR in Indonesia.

So parliamentary treshold should be 100%/500 =.2%

My bro angrily explains about some winner takes all system that I do not quite understand and as far as I know is NOT implemented in Indonesia (unlike in US).

So what's going on?

According to Wikipedia, the threshold is actually 3.5%.

Your logic is mistaken. Your calculation is based on the assumption that a party should be allowed into the DPR if it gets enough votes for 1 candidate across the whole of Indonesia. In fact, the threshold is set so that they need to get enough votes for 17 members. This reduces the problem of having a legislature with lots of very small parties (the small parties tend to have disproportionate influence).

Note that because the election is actually done proportionally within each district (and voters can vote for individual candidates), the eventual numbers may still not be exact.

  • is parliamentary threshold common in democracy?

  • @user4951 It is common in democracies that use some sort of proportional representation. It is not needed in democracies that use "first past the post" - line the UK and USA. In those countries there is a very strong tendency for there to be two very dominant parties (it is quite easy to get 10% of the vote in every constituency and none of the seats).

    @user4951 en.m.wikipedia.org/wiki/Electoral_system_of_Germany if you scroll to the voting system section you can see the German Second vote, the PR bit requires a party reach a 5% threshold.
