ABSTRACT
The use of environmental planning tools for optimum
solid waste landfill siting taking into account all environmental implications
was carried out by applying Life Cycle Analysis (LCA) to enhance the research information obtained from initial analysis
using Geographical Information Systems (GIS). The objective of this study is to identify the most eco-friendly
landfill site by conducting a LCA analysis upon 5
potential GIS generated sites which
incorporated eleven important criteria related to the social, environmental,
and economical factors. The LCA analysis utilized the
daily distance covered by collection trucks among the 5 selected landfill sites
to generate inventory data on total energy usage for each landfill sites. The
planning and selection of the potential sites were facilitated after conducting
environmental impact analysis upon the inventory data which showed the least
environmental impact.
Keywords: Geographic information system; impact
analysis; life cycle assessment; landfill siting
ABSTRAK
Penggunaan alat
pengurusan alam sekitar untuk penempatan tapak pelupusan sampah yang optimum
dijalankan dengan mengaplikasikan kaedah Analisis Kitaran Hayat (LCA) untuk menambahbaikan
maklumat kajian yang telah dijanakan oleh Sistem Maklumat Geografi (GIS). Objektif kajian ini
adalah untuk mengenalpasti tapak bahan buangan yang paling mesra alam dengan
menjalankan satu analisis LCA di 5 kawasan potensi
tapak yang dijana oleh GIS yang sudah pun
menggabungkan 11 kepentingan kriteria berkaitan dengan kemasyarakatan, alam
sekitar dan faktor-faktor ekonomi. Analisis LCA menggunakan jumlah jarak yang dilalui oleh lori kutipan setiap hari di antara 5 tapak bahan buangan terpilih untuk menjana
inventori data ke atas jumlah penggunaan tenaga untuk setiap tapak bahan
buangan. Perancangan dan pemilihan untuk tapak yang paling sesuai dipermudahkan
setelah dijalankan satu analisis impak ke atas inventori data tersebut untuk
menentukan tapak pelupusan sampah yang mana akan menghasilkan kesan yang minimum terhadap alam sekitar.
Kata kunci: Analisis kitaran hayat; penilaian
impak; sistem maklumat geografi; tapak pelupusan sampah
