 Special dedicates to my beloved parents, family, teacher Mr
  Noorsuhaili bin Ali @ Md Noor and my fellow friends, who
had strongly encouraged and supported my entire journey of
                          learning.
                         ACKNOWLEDGEMENT




     Alhamdulillah and thanks to the Almighty Allah, The Most Glorious
and The Most Merciful, for giving me strength and bless therefore I able to
accomplish and complete my MRSM Young Scientist Programmed project
and also be able to complete my thesis.

      Firstly, a would like to express a thousand of thanks to my supervisor,
Mr Noorsuhaili bin Ali @ Md Noor for the assistances, admonitions,
patients and guidance towards the progress of this project.

      This acknowledgement also goes to all my friends for the supports,
assistance and opinions during the development of this project.

     Finally I would like to give millions of thanks to any party or individual
which are directly or indirectly involve in order accomplishing this project,
my parent, family and friends, especially Mohd Hosni Salleh and to MRSM
Tun Ghaffar Baba itself.
                                   ABSTRACT


      The usage of PLC in controlling an automated system is wide
ranging. The PLC used in the system is the OMROM for real world
application because it can handle high voltage while the IDEC Micro smart
in project models because it only can handle low voltage. The were
programmed with a certain programmed to enable efforts in controlling the
electric supply by either connecting or disconnecting it from a hostel. It can
also be set according to differing time and days.



      The system was installed in early March 2007. Readings collected
show a decrease in electricity bills of 15% to 35% while the number of
students who leave the hostel in time increases 85%.In a roundabout way,
it also can decrease the rate of vandalism and the of stolen cases in
hostels.



      Conclusion, with this automatic control system that utilizes PLC is
very beneficial not only to this college but all the hostel cross continent in
respect of electricity billings or even increasing the discipline of students in
attending official or unofficial functions of the college. We hope that all
boarding schools in Malaysia would apply this system in their hostels as it
is very practical and efficient.
