Hello i'm from malaysia ..u can do the query like this, SELECT nameoftable."TGL Libur" ,nameoftable.keterangan
CONCAT(nameoftable.tahun,' - ',nameoftable.semester) AS tahunsemester
FROM nameoftable
ORDER BY nameoftable.tahun, nameoftable.keterangan

hope this will give u a piece of help ,i will not solve the issue but you the keyword for join together the column in temporary column is CONCAT ..OK.
