Cristhiano,

Note that your world file indicates a pixel size of 30 degrees by
30 degrees, so your map extent is covered by a fraction of the first
pixel.

If you mean the pixels to be 30 meters by 30 meters you could try replacing
30 and -30 with 0.00027 and -0.00027 and see if it is roughly right.  But
you should likely review exactly where you think this raster file is in the
world.

Best regards,
