Dewasa ini, kita boleh dapati kebanyakan lembah-lembah bukit telahpun menjadi
tumpuan peneroka. Berlalunya masa membawa kepada perubahan cita rasa disamping
keperluan yang lebih selesa. Kini, pembangunan bukan sekadar di kawasan lembah atau
landai sahaja, malah pembangunan infastruktur mula menjalar ke kawasan tanah tinggi.
Namun adakah ia selamat? Untuk mencapai tujuan ini, analisis kestabilan cerun adalah
penting dan mesti dilakukan dengan sempurna untuk mengelakkan berlakunya kegagalan
cerun daripada berlaku. Walaupun terdapat banyak kaedah-kaedah analisis yang
digunakan dalam bidang Geoteknik, namun keputusan analisis tersebut tidak dapat
menghasilkan gambaran keputusan yang menyeluruh untuk suatu kawasan yang besar.
Dalam projek ini, prinsip Geographical Information System (GIS) digunakan bersama
dengan teori kaedah analisis cerun tidak terhingga dalam membuat analisis kestabilan
cerun. Penggunaan prinsip ini dapat menghasilkan satu imej peta yang dapat memaparkan
factor keselamatan cerun bagi seluruh tempat kajian kepada para pengguna. Justeru itu,
kawasan yang merbahaya di kawsan bukit dapat dikenalpasti dan pembinaan tidak
dijalankan di kawasan berkenaan. Walaupun banyak perisian computer diperkenalkan di
pasaran namun dalam projek ini, hanya dua perisian yang digunakan iaitu perisian
ERDAS Imagine Ver. 8.3 dan perisian SLOPE/W. Methodologi yang terdapat dalam
laporan ini diharapkan akan memberi manfaat kepada orang yang ingin menggunakan
kedua-dua perisian ini dalam membuat analisis kestabilan cerun dan ahli penyelidik lain.

The aim of this study is to utilize the GIS techniques for slope instability assessment and
prediction in the University Sains Malaysia main campus new hostel area, in the Penang
State, peninsular Malaysia. GIS, can assist in terms of speeding up processing and
moreover in the hazard zonation and prediction assessment.
Nowadays, the problems of slope failure have become more serious. High speed
development without hesitation and doubt to build a structure on hill due to the shortage
of lands for certain countries contributed to the increasing of slope failure case. By this
reason, the work of maintenance for reduce the slope failure become more important
nowadays, so the system are needed for some person such as consultant, contractor,
developer and government to prevent the slope from fail effectively.
The research of project has a purpose to produce a system which can help to reduce the
risk to slope failure by using ERDAS Imagine Version 8.3. Few steps already be
recognize in this research such as data collection, confirm type of data which used to
analysis the slope stability and system monitoring. The results are produced in images
and these images should show the factor of safety for the entire area of a hill. From these
maps, we can know and define the danger zones on a hill.
The result of analysis would be check by using Slope/W for determined the effectiveness
of system. These software are user friendly and they can be used to do so many spatial
analysis and others. Hopefully in this project, the methodology of analyzing slope
stability using these two programs can be beneficial to those who are interested in doing
slope stability analysis.
