Di Kampus Kejuruteraan USM, masalah bau adalah masalah biasa yang kini dihadapi oleh penghuninya. Kajian ini memberikan penekanan dalam mengkaji tahap keseriusan masalah bau, mengenal pasti faktor-faktor yang mempengaruhi konsentrasi bau dan seterusnya menghasilkan peta konsentrasi bau di Kampus Kejuruteraan USM. Walau bagaimanapun, kefahaman yang mendalam mengenai bau seperti ciri-ciri dan dimensi bau, cara-cara mengira bau dan faktor-faktor yang mempengaruhi bau adalah penting terutamanya diperingkat permulaan kajian. Pengumpulan data konsentrasi bau adalah menggunakan ‘Infield Olfactometer’ manakala data meteorologi seperti kelajuan angin, suhu dan kelembapan menggunakan meter cuaca. Tambahan lagi, keadaan cuaca harian seperti hari panas dan hari hujan juga telah diambil. Data ini telah diambil pada dua sesi, iaitu pada waktu pagi dan malam selama empat minggu dalam pelbagai keadaan cuaca dan kestabilan atmosfera. Data ini kemudiannya diproseskan dan diinterpolasi untuk menghasilkan peta konsentrasi bau menggunakan perisian GIS- Edisi IDRSI Selva. Melalui peta yang dihasilkan, tahap keseriusan bau di setiap lokasi dalam pelbagai keadaan cuaca dapat dikenal pasti. Selain itu, hubungan antara bau di kampus ini dan punca-punca bau telah ditunjukkan melalui peta interpolasi dan peta profil. Seterusnya, faktor-faktor yang mempengaruhi konsentrasi bau seperti tahap kelajuan angin dan arah angin, lokasi dan jarak dari punca bau tersebut serta kestabilan atmosfera juga telah dikaji. Adalah direkemenkan agar permodelan ruang yang digunakan dalam kajian ini digunakan dalam perancangan alam sekitar dan langah-langkah yang sewajarnya dalam menyelesaikan masalah bau di Kampus Kejuruteraan USM.

In USM Engineering Campus, odour nuisance is common problem that currently being faced by the residents. This research is focused on finding the severity of odour problems, distinguishes the factors that may influence odour concentrations and hence produce odour concentrations maps of USM Engineering Campus. However, crucial understanding regarding odour such as the characteristics and dimensions of odour, method in measuring odour and the general factors that affects the behaviour of odour is important especially in early stage of the research. The collection of odour concentrations data were taken by using Infield Olfactometer while the meteorological data such as wind speed and humidity were taken using weather meter. In addition, daily weather conditions such as sunny or rainy day is also taken in consideration. The data were collected for two sessions that is in the morning and evening for four weeks with various weather conditions and atmospheric stability condition. These data were processed and spatially interpolated to produce odour concentration map using GIS software – IDRISI Selva Edition. From the interpolated map, the severity of odour at each location can be detected at various weather conditions. Other than that, the relationship between the odour in USM Engineering Campus and its source were shown by interpolated map and profile map. Consecutively, probable factors that affect odour concentration such as wind speed and its direction, the locations and distance from the source of odour and the atmospheric stability were discovered. It is recommended that the GIS spatial modelling approach use in this research to be used in healthy environmental planning and proper measure in solving odour problem in USM Engineering Campus.
