Abstract

There is a need for managing and displaying drug addiction phenomena and trend at both spatial and temporal scales. Spatial and temporal assessment on drug addiction in Terengganu was undertaken to understand the geographical area of district in the same cluster, in addition, identify the hot spot area of this problem and analysis the trend of drug addiction. Data used were topography map of Terengganu and number of drug addicted person in Terengganu by district within 10 years (2004-2013). Number of drug addicted person by district were mapped using Geographic Information system and analysed using a combination of multivariate analysis which is cluster analysis were applied to the database in order to validate the correlation between data in the same cluster. Result showed a cluster analysis for number of drug addiction by district generated three clusters which are Besut and Kuala Terengganu in cluster 1 named moderate drug addicted person (MDA), Dungun, Marang, Setiu and Hulu Terengganu in cluster 2 named lower drug addicted person (LDA) and Kemaman in cluster 3 named high drug addicted person(HDA). This analysis indicates that cluster 3 which is Kemaman is a hot spot area. These results were beneficial for stakeholder to monitor and manage this problem especially in the hot spot area which needs to be emphasized.

Abstrak

Terdapat keperluan untuk menguruskan dan memaparkan fenomena dan tren penagihan dadah dalam skala ruang dan masa. Penilaian ruang dan masa bagi masalah penagihan dadah di Terengganu telah dijalankan untuk memahami kawasan geografi daerah-daerah yang berada dalam ketegori yang sama, di samping untuk mengenal pasti kawasan panas dan juga menganalisis trend penagihan dadah. Data yang digunakan ialah peta topografi negeri Terengganu dan bilangan penagih dadah mengikut daerah dalam tempoh sepuluh tahun (2004-2013). Bilangan penagih dadah bagi setiap daerah telah dipetakan menggunakan sistem Maaklumat Georgafi (GIS) dan dianalisis menggunakan gabungan analisis multivariat iaitu kluster analisis yang diaplikasikan ke dalam pengkalan data untuk mengesahkan hubungan di antara data yang berada dalam kategori yang sama. Keputusan kajian menunjukkan, hasil analisis kluster bagi bilangan penagih dadah mengikut daerah dibahagikan kepada tiga kategori iaitu Besut dan Kuala Terengganu dalam kluster satu yang dinamakan sederhana penagih dadah, Dungun, Marang, Setiu dan Hulu Terengganu dalam kluster dua, dinamakan kurang penagih dadah dan Kemaman dalam kluster tiga dinamakan tinggi penagih dadah. Analisis ini menunjukkan bahawa kluster ke tiga iaitu Kemaman merupakan kawasan panas penagih dadah. Hasil kajian ini sangat berguna kepada pihak berkepentingan untuk memantau dan menguruskan masalah ini terutamanya bagi kawasan panas yang memerlukan pengkhususan.

 

Kata kunci: penagihan dadah, GIS, analisis multivariat, analisis kluster
