Peningkatan
aktiviti perbandaran dan perindustrian telah mencetuskan masalah pengurusan
sisa pepejal. Sebagai usaha penyelesaian, pendekatan bersepadu telah dipilih bagi
menguruskan sisa pepejal. Membangunkan dan melaksanakan rancangan pengurusan
sisa pepejal bersepadu perlu melibatkan gabungan teknologi dan pilihan yang
sesuai dengan keadaan dan undang-undang tempatan. Kajian ini menunjukkan Proses
Analisis Hierarki (PAH) berpotensi sebagai kaedah membuat keputusan yang boleh
digunakan dalam proses pemilihan teknologi pengurusan sisa pepejal. Tiga aras
hierarki dibangunkan dengan matlamat di aras tertinggi, diikuti oleh kriteria
dan alternatif. Dengan menggunakan teknik ini, penentuan keutamaan untuk semua
teknologi pengurusan sisa pepejal yang dipertimbangkan akan ditentukan dan
teknologi dengan nilai keutamaan tertinggi lebih sesuai untuk dibangunkan.
Analisis sensitiviti dilakukan bagi menguji sensitiviti keputusan akhir
terhadap perubahan kecil penilaian. Aplikasi PAH dalam menentukan keutamaan proses
pemilihan teknologi pengurusan sisa pepejal diperjelaskan dalam kajian ini
berdasarkan kepada kajian kes di Majlis Perbandaran Port Dickson. Hasil
analisis menunjukkan kombinasi teknologi kitar semula dan pengkomposan sesuai
diaplikasikan di daerah Port Dickson.
Kata
kunci: Proses analisis hierarki; pengurusan sisa pepejal
ABSTRACT
The
growth in urbanization and industrial activities has caused solid waste management
problems. As a solution the integrated approach has been chosen to manage the
solid waste. Developing and implementing integrated solid waste management
involve combined technologies and alternatives which are suitable with local
laws condition. This research showed that Analytical Hierarchy Process (AHP)
has the potential as a decision making tool that can be used in selecting
process of solid waste management technology. Three levels hierarchy was
developed with the goal at the top level, followed by criteria and
alternatives. By using this technique, the priority of each considered
technology will be determined where technology with the highest priority is
more suitable to be developed. Sensitivity analysis was carried out to test the
sensitivity of final decision towards inconsistency of judgement. Application
of AHP to determine priority in solid waste management technology was explained
in this research based on a case study in the Port Dickson Municipal Council.
Analysis of result showed that the combination of recycling technology and composting
are suitable to be applied in the Port Dickson district.
