See these two pages for a description of the markings (https://www.jewishgen.org/infofiles/manifests/bsi/ ) and common abbreviations used (https://www.jewishgen.org/infofiles/manifests/glossary.html )

Without seeing an image of the manifest, it is difficult to say with certainty.  Are you sure that "JPG" isn't "LPC" (likely to be public charge)?  1140 is the time of the BSI hearing.  Monn is likely the surname of the inspector.
