Abstrak: Kajian ini menerangkan tentang penggunaan maklumat geologi dan penilaian terain dalam Sistem Sokongan Membuat Keputusan (Decision Support System, DSS) untuk menangani masalah kejadian tanah runtuh di kampus Universiti Kebangsaan Malaysia (UKM) Bangi, Malaysia. Zon-zon prioriti telah diperolehi daripada analisis sistematik data lapangan dan tindan-lapis peta terain geologi, lokasi tanah runtuh dan pelbagai elemen berisiko dengan menggunakan teknologi Sistem Maklumat Geografi. Antara kriteria-kriteria yang digunakan untuk mengenal pasti zon-zon prioriti tersebut ialah keseriusan impak tanah runtuh, keboleh-tangani melalui langkah pencegahan, keterdesakan dalam keperluan untuk menyelesaikan masalah dan potensi kemerosotan. Berdasarkan hasil yang diperolehi, DSS berasaskan geologi memudahkan Jabatan Pembangunan dan Penyelenggaraan (JPP) UKM dalam perancangan dan membuat keputusan terhadap zon-zon tersebut.

Kata kunci: Sistem Sokongan Membuat Keputusan, tanah runtuh, peta terain geologi, zon prioriti

Geological input for Decision Support System to manage the risk of disasters: A case study of Universiti Kebangsaan Malaysia

Abstract: This paper describes the use of geological information and terrain assessment in a Decision Support System (DSS) to address landslide problems in the campus of Universiti Kebangsaan Malaysia (UKM) in Bangi, Malaysia. Zones of priority were derived from systematic analysis of field data and overlays of the geological terrain map, landslide location, and various elements at-risk, using Geographic Information System (GIS). Among the criteria used to identify the zones of priority are seriousness of landslide impacts, manageability of mitigating measures, urgency in the need to resolve the problem and the potential for further deterioration. Results indicate that this geological-based DSS facilitates the Development and Maintenance Department (Jabatan Pembangunan dan Penyelenggaraan, JPP) of UKM in planning and decision-making with respect to such zones.

Keywords: Decision Support System, landslide, geological terrain mapping, priority zones
