    If you want UTM zone 48, you need to choose "UTM" from the projection list, then you will be able so select zone -48 (southern hemisphere) or 48 (northern hemisphere).  Those zones user CENTRAL MERIDIAN equal to 105.

    You can't use 103.5 for ORIGIN LATITUDE, because it is not a valid latitude.  You can use it for CENTRAL MERIDIAN, though.
