Pembentukan model faktor bahan dan peralatan sebagai penyebab kemalangan dalam industri pembinaan Mass Rapid Transit (Development of materials and equipment factor model in contributing to accidents in the Mass Rapid Transit construction industry)

Mohammad Lui Juhari, Kadir Arifin

Abstract


Kadar kemalangan pekerjaan di industri pembinaan adalah di antara yang tertinggi berbanding sektor perindustrian yang lain. Faktor bahan dan peralatan merupakan antara penyumbang kepada kemalangan pekerjaan di tapak pembinaan berbanding dengan faktor-faktor lain. Kajian ini dijalankan bagi mencadangkan penilaian model faktor bahan dan peralatan dalam menyumbang kepada kemalangan pekerjaan dalam industri pembinaan Mass Rapid Transit di Malaysia (MRT) di Malaysia dengan menggunakan analisis faktor pengesahan (CFA). Kajian kuantitatif ini dijalankan dengan mengedarkan borang soal selidik secara rawak untuk mendapatkan data bagi projek pembinaan MRT di sekitar Lembah Kelang. Sebanyak 180 maklumbalas responden telah diterima merangkumi kumpulan pengurusan/profesional dan kumpulan pekerja pembinaan. Kemudian, analisis CFA dijalankan menggunakan perisian IBM SPSS-AMOS bagi mengesahkan model cadangan dengan memeriksa perhubungan di antara pemboleh ubah yang diperhatikan dan pemboleh ubah pendam. Pemboleh ubah pendam adalah faktor bahan dan peralatan; aspek kesesuaian bahan dan peralatan "sesuai"; keadaan bahan dan peralatan "keadaan"; rekabentuk perlindungan keselamatan "rekabentuk"; dan pengetahuan mengenai bahan dan peralatan yang digunakan "pengetahuan". Manakala pemboleh ubah yang diperhatikan merupakan 19 item bagi keempat-empat aspek di bawah faktor bahan dan peralatan. Keputusan CFA mengesahkan bahawa faktor bahan dan peralatan dalam menyumbang kepada kemalangan pekerjaan dalam industri pembinaan MRT adalah terdiri daripada keempat-empat aspek yang dikaji iaitu "pengetahuan", "rekabentuk", "keadaan", and "sesuai". Hasil dapatan kajian ini perlu diberi perhatian oleh semua pemegang taruh dengan mengambil langkah-langkah penambahbaikan yang bersesuaian dalam usaha untuk mencegah kemalangan pekerjaan di industri pembinaan MRT pada masa akan datang.

Katakunci: analisis faktor pengesahan, faktor bahan dan peralatan, industri pembinaan, kemalangan pekerjaan, keselamatan dan kesihatan pekerjaan, mass rapid transit

Occupational accident rates in the construction industry are among the highest compared to other industrial sectors. Materials and equipment factor is one of the contributing to occupational accidents in the construction industry. This study was conducted with objective to propose an assessment of the materials and equipment factor model in contributing to occupational accidents in the Mass Rapid Transit di Malaysia (MRT) construction industry in Malaysia by using confirmatory factor analysis (CFA). This quantitative research was conducted by distributing a survey questionnaire randomly to obtain data from the MRT construction project around the Klang Valley. A total of 180 respondent responses were received from management/ professional and construction site workers group. Then, CFA analysis was performed by using IBM SPSS-AMOS to validate the proposed model by examining the relationships between observed variable and latent variable. Latent variable are materials and equipment factor; suitability of the materials/equipment; conditions of the material/equipment; safety protection design; and knowledge of the materials/equipment used. Whereas the observed variables are 19 items for all four aspects under materials and equipment factor. The CFA result validates that the materials and equipment factor in contributing to occupational accidents in the MRT construction industry is consist of all four aspects studied i.e. "knowledge", "design", "condition", and "suitable". This result of research should be focused by all MRT construction stakeholders where suitable improvement measures can be taken in order to prevent occupational accidents from occurring in the future.
