Answer 1

your subquery doesn’t have column idspesialis

try this,

(
    SELECT idPegawai, NamaPegawai AS NamaDokter, idspesialis
    FROM tpegawai
) d

your full query should look like below,

SELECT a.*
    , b.*
    , c.*
    , e.*
    , d.*
    , f.*
    , g.*
FROM ckehamilan a
    INNER JOIN pasien b
        ON a.noRM = b.noRM
    INNER JOIN 
        (
            SELECT idPegawai, NamaPegawai AS NamaDokter, idspesialis
            FROM tpegawai
        ) d
        ON a.idPegawai = d.idPegawai
    LEFT JOIN spesialis e
        ON e.idspesialis = d.idspesialis
    INNER JOIN 
        (
            SELECT idPegawai , NamaPegawai AS NamaParamedis
            FROM tpegawai
        ) f
        ON a.idparamedis = f.idPegawai
    LEFT JOIN imunisasi g
        ON a.idimunisasi = g.idimunisasi
    INNER JOIN ruang c
        ON a.idruang = c.idruang
