| Summary: | The problem of drug addiction in Malaysia is worsening and causes harm to the well-being of the
population of Malaysia. A report published in 2018 states that 133,684 or 0.4% of the Malaysian
population are drug addicts. Furthermore, 56% of all inmates in the federal prison are locked-up
because of drug-related offences. This study aim is to identify the hotspots for drug addicts in
Selangor, Malaysia. This study uses three geostatistical techniques, kernel density estimation
(KDE), Getis-Ord Gi*, and IDW to map the hotspots for drug addicts. The National Anti-Drug
Agency (NADA) provides the data for this study which consists of 2997 cases of drug addict
under supervision (DAUS) in 2016. The data are analysed using ArcGIS Pro 2.4 software. The
individual DUAS represents a point vector data format with WGS 1984 Web Mercator
projection. Hotspot analysis is performed using kernel density estimation (KDE), Getis-Ord Gi*
and IDW. The results show eight statistically significant hotspots for drug addicts in the subdistricts (99% confidence level and p-value < 0.001). The locations with significant hotspots for
drug addicts are Bandar Serendah, Pandamaran, Bandar Klang, Bandar Kajang, Dengkil, Bandar
Ampang, Bandar Damansara, and Semenyih sub-districts. This study provides spatial
information that helps law enforcement agencies identify drug hotspot areas and use this
information to create and enhance a defensible safe neighbourhood. The outcome of this study
facilitates law enforcement through better strategic planning for reducing drug addict hotspot
areas. |
