Publisher : USN Kolaka

The inter-relation between land surface changes (land cover) and local climate affect other atmospheric phenomenon such as clouds and their formation and properties. The Earth’s hydrological cycle is complex system describing the mutual relationship between Earth's surface and the atmospheric component, as a consequence, small changes to one part of the system can accrue to have larger effects on the other system as a whole. NDVI and cloud optical thickness obviously allocated in wet season than dry season, with fluctuated in uphill and downhill polynomial. According to wet season, downhill line of cloud optical thickness ware detected as mean value on every November during 14 years. At 1 percent of NDVI fluctuation declined two times of optical depth otherwise. Absolute result in wet season may be due to more stable and homogeneous data variability. Least sunlight for vegetation growth and the least amount of evapotranspiration energy, less cloud forms.

Publisher : USN Kolaka

The physical typology of the coastal area in this study is built from a combination of landforms, slopes, and materials. The research method used is a field survey to validate land units on secondary maps and GIS analysis to process typology maps of coastal areas based on a process-response system matrix. The results of this study indicate that the TAD coastal area has only one coastal typology, namely the type of land deposition with a gentle slope characteristic, the constituent material in the form of loose material and the terrain which is dominated by alluvial plains. As a result, in general, the coastal area of Teluk Ambon Dalam is easy to develop and manage.

Burned Region Analysis using Normalized Burn Ratio Index (NBRI) in 2019 Forest Fires in Indonesia (Case study : Pinggir-Mandau District, Bengkalis, Riau) Risty Khoirunisa; Mucsi Laszlo
Geographica: Science and Education Journal Vol 2, No 1 (2020): December
Publisher : USN Kolaka

Forest fire is a hazard that common to happen in Indonesia every year, whether from natural or human-induced factor. These fires can be uncontrollable and destruct the forest. Furthermore, these can affect the health of the people, the biodiversity, the disruption in transportation and the socioeconomic of the affected region. The total area calculated was burned is 875.756 hectares in the entire country in 2019, the biggest lost after 2015. Thus, the study conducted in some affected area in Riau Province, Sumatra, Indonesia where consistently suffered from the fire by remote sensing and GIS approach. The study of the burned area was investigated using a formulated index called NBRI (Normalized Burn Ratio Index) based on Near Infrared (NIR) and Shortwave Infrared (SWIR) spectral reflectance of Landsat 8 OLI/TIRS Satellite Imageries. The two values of NBRI from post and pre-fire images were calculated to define differenced NBR (dNBR) to assess its severity. It is found that about 4,7 %, or about 11.014 hectares of the area of the study which was about 234.864 hectares was burned. 90,3 % of the burned area was located in the vegetated area, especially forest area with 50,25 % of those cover the burned area. The validation was using visual interpretation based on SPOT 7 pansharpened images resulted in acceptable agreement with kappa coefficient value of 0,83. The information on the maps can be used to develop rehabilitation planning or predict the area for potential fire hazard in the future.

Publisher : USN Kolaka

This study aims to: (1) To determine the spatial interaction of the driving factors of Kendari City and South Konawe District based on the attractiveness of Kendari City as a center of higher education (2) To find out the spatial interactions and the driving factors of Kendari City and South Konawe District based on the attractiveness of Kendari City as the center of the vegetable commodity market. This research uses descriptive analysis method, Location Quotient (LQ) and Gravity analysis. The results show (1) Spatial interaction and driving factors of Kendari City and South Konawe Regency based on the attractiveness of Kendari City as a center of higher education, it can be seen that the one with a very strong interval value is Ranometo District. While the Konda District has a fairly strong interval value and 20 other Districts have a non-strong interval value. The dominant motivating factor in choosing tertiary institutions is the ease of socializing. (2). The spatial interaction between Kendari City and South Konawe Regency based on Kendari City as the center of the vegetable commodity market can be seen that West Ranometo District and Konda District have very strong interval values, while Landono District has Strong interval values. The dominant driving factor that causes farmers to sell their agricultural products in Kendari City, especially the Baruga market, is because this market has a difference with other markets in Kendari City.
