Kejadian angin ribut melanda beberapa bahagian di Malaysia terutamanya di rantau Utara telah memberi kesan buruk kepada manusia dan menyebabkan kerosakan kepada harta benda dan kematian. Usaha mitigasi risiko bencana perlu dilakukan untuk mengurangkan akibat angin ribut kepada sektor perumahan di kawasan luar bandar. Objektif utama kajian ini adalah untuk membangunkan rangka kerja konseptual pengurangan risiko angin untuk rumah kampung di Utara Semenanjung Malaysia. Kajian soal selidik menggunakan lima mata skala Likert telah diedarkan kepada dua kumpulan responden, iaitu kumpulan pakar dan komuniti di dalam kajian. Teknik pensampelan bukan probabilistik dipilih sebagai persampelan bertujuan dan dianalisis menggunakan statistik SPSS IBM versi 21. Data sekunder mengenai kajian pasca ribut angin menunjukkan kejadian angin ribut yang berlaku pada bulan April, Mei dan Oktober semasa tempoh inter-monsun di Utara Semenanjung Malaysia merosakkan bumbung rumah kampung, oleh itu penggantian diperlukan. Indeks kepentingan relatif diperkenalkan untuk menganalisis pengaruh yang signifikan terhadap faktor risiko yang telah dikenalpasti. Sementara itu, korelasi Spearman telah dilakukan untuk memastikan risiko dan ancaman di kalangan pembolehubah dalam mitigasi bahaya angin. Oleh itu, rangka kerja untuk mengurangkan risiko bencana angin untuk rumah kampung di Semenanjung Malaysia mendapat kedudukan pengenalan risiko, dan juga hierarki risiko dan ancaman berlaku dalam fasa mitigasi. Kedudukan pengenalan risiko menunjukkan pelaksanaan reka bentuk di sistem bumbung rumah kampung sebagai faktor risiko pra-dikenal pasti yang paling signifikan. Rangka kerja tersebut menunjukkan bahawa peranan kod pada pemuatan angin, peristiwa bencana angin dan pelaksanaan reka bentuk sangat penting dalam risiko hierarki dan ancaman. Kitaran proses terlibat dalam fasa pembinaan semula untuk menghasilkan kualiti rumah kampung yang berkualiti. Cabaran-cabaran dan langkah-langkah pencegahan yang ditemui sepanjang proses ini perlu diambil kira untuk penambahbaikan yang berterusan dari semasa ke semasa. Akhir sekali, kajian ini akan memberi manfaat kepada pembuat dasar dan badan tadbir urus dalam membuat keputusan dan membangunkan garis panduan mengenai pengurangan risiko bencana angin. _______________________________________________________________________ Windstorm event hit several parts of Malaysia particularly in the Northern region has severely affected humans and causing damage to the properties as well as fatality. Disaster risk mitigation efforts should be exerted to reduce the disastrous consequences of windstorm to the housing sector in rural area. The main objectives of the study are to develop conceptual framework of wind risk mitigation for rural houses in Northern Peninsular Malaysia. Questionnaire survey using five points Likert-scale was distributed to two groups of respondents, namely the expert and community group in the study. A non-probabilistic sampling technique was chosen as a purposive or judgmental sampling and analysed using IBM SPSS statistics version 21. The secondary data on post windstorm survey shows windstorm event predominantly occurs during the month of April, May and October during the inter-monsoon period in the Northern Peninsular Malaysia tremendously damage the rural houses roof cladding, hence, replacement is needed. The relative importance index was introduced to analyse significant influence on pre-identified risk factors. Meanwhile, Spearman’s rho correlation was performed to ascertain the risk and threat among the variables in the wind hazard mitigation. Thus, framework on the wind disaster risk mitigation for rural houses in Northern Peninsular Malaysia derived risk identification rank, and also risk hierarchy and threats took place in mitigation phase. The risk identification rank showed implementation of design in rural roofing system as the most significant preidentified risk factor. The framework indicated that roles of codes on wind loading, wind disaster event and design implementation are significantly important in risk hierarchical and threat. A process cycle involved during the reconstruction phase to produce a good quality of rural houses. Challenges and preventive measures encountered throughout the process shall be taken into account required continuous improvement over time. Finally, this study shall benefit the policy maker and governance body in decision making and develop a guideline on the wind disaster risk mitigation.
