Evaluation and comparison of bivariate and multivariate statistical methods for landslide susceptibility mapping (case study: Zab Basin)

Landslides are among the great destructive factors which cause lots of fatalities and financial losses all over the world every year. Studying of the factors affecting occurrence of landslides in a region and zoning the resulting damages will certainly play a crucial role in mitigating such phenomena. In this research, through geological maps and field studies, we primarily prepared a map for landslide distributions in Zab basin-an area of 520 km 2 in the southwest mountainsides of West Azerbaijan Province. By applying other source of information such as the existing thematic maps, we studied and defined the factors (slope, slope aspect, distance to road, distance to drainage network, distance to fault, land use and land cover, geological factors, horizontal gravity acceleration of earthquakes, and climatic condition of the studied area) that affect occurrence of the landslides. To get better precision and higher speed and facility in our analysis, all descriptive and spatial information were entered into geographic information system (GIS) system and Ilwis software. We also used Satellite images (Landsat ETM + and SPOT 5), producing land cover and landslide-inventory maps, respectively. After preparation of the influential parameters on landslides, we drew the zoning maps of slide hazard via four different statistical methods and then evaluated and compared them. By analyzing the obtained index and by comparing landslide distribution map and zoning map of landslide susceptibility prepared by each of the methods in GIS environment, we found that bivariate method of information value analysis, bivariate method of density-area, multivariate method with linear regression analysis, and multivariate method of discriminate analysis take priority, respectively. Finally, as this research shows, despite their simplicity, bivariate statistical methods have more acceptable precision than multivariate methods, and consequently, they are more compatible with landslide susceptibility of the region. From the results, lithology, slope, annual rainfall, land cover, slope aspect, distance to waterway, distance to road, horizontal gravity acceleration, and distance to fault are very influential to landslides in the region

Fertility status of peat soils after 15, 20 and 25 years of oil palm (Elaeis Guineensis) plantation operation / Azhari Baharin

The fertility status of peat soil changed after being planted with oil palm tree for several years. This study intends to compare the nutrient status of peat soils planted with oil palm tree after 15, 20 and 25 years of operation. In this study, soil samples of peat soils were collected at FELCRA Berhad Sungai Manila, Perak by using random sampling method. 30 samples were taken from different areas of 15 years, 20 years and 25 years planting oil palm tree and it’s were analyzed for their physical and chemical properties. The results showed that the colors between the three areas are similar which is very darks greyish brown (10YR 3/2). Soil bulk density is considered low (0.35 g/cm³) at area 15 years planting oil palm tree compared to others area. Area of 25 years is more acidic compared to other areas and it is have high of phosphorus content compared. Based on this study, it is suggested that management of plantation must considered all factors such as applying fertilizer to grow oil palm tree for proper management at peat lands

A study on purchase intention towards AgroMas brand / Roemilia Baharin

This paper is to examine purchase intention towards AgroMas brand. However, there not much study about the purchase intention towards AgroMas brand which mostly previous study is about SMEs product but they do not explained detail what brand they focusing on. Thus, the theoretical framework was done. With a simple random sampling method used in this research, about 80 questionnaires distributed to the consumers before the results have revealed relationship and significant of conceptual framework of this topic. The researcher distributed the questionnaires among the consumers that come to Giant Senawang during weekdays. There are three conceptual factors which are brand affect, brand familiarity, and brand attitude has been analysed. Then the result of the study would indicate the main influential purchase intention towards AgroMas brand
