Answer 1

SELECT `ID_KATEGORI_RETRIBUSI`, `NAMA_KATEGORI_RETRIBUSI`, `TANGGAL`,
CONCAT('Rp ', FORMAT(JUMLAH, `0))` as JUMLAH
has a stray backtick ('`')
I think you want this instead:
SELECT `ID_KATEGORI_RETRIBUSI`, `NAMA_KATEGORI_RETRIBUSI`, `TANGGAL`,
CONCAT('Rp ', FORMAT(JUMLAH, `0)) as JUMLAH
Turns out there is a codeingiter setting for this:
$this->db->_protect_identifiers=false;
