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
