Dear rahman,
The talismanic inscription on one side... (reference from Kitab
Aji Mantra Guna), which translated to be "untuk menangkap maling". Accordingly, if a thief stole something from a place which is guarded by this talisman, the person would not be able to find his way out.
The inscription on the other side (reference from Kitab
Al-Aufaq), it is to protect the wearer from
sihir/sirep ,(a type of spell to lull or put one to sleep) and to prevent the wearer from falling asleep while on guard.
(Insya allah bisawab).
