Naik = ke atas
so it could be 'Saya tidak mau naik'?
What about "Saya tidak mau naik atas"?
For direction, I think we cannot omit the "ke"
This is very confusing ..if you go down it is turun ke bawah .turun being GO but if you go up it naik ke atas ...naik being GO ... why would they do this to themselves why could we just say ...saya mua pergi naik ..or ..saya mua pergi bawah
In this case 'go' is not beeing as 'naik' or 'turun'. But, you have to use a full phrase. 'Go up' means 'naik' and 'go down' means 'turun'.
That is how the grammar working
For some context, you could just say "saya tidak mau naik"
Tidak mau means doesnt want to. So you could only say that if you dont want to go up
But that's what is said here no?
