Demystifying the Geography of Urbanization in Indonesia (Case Study: Southeast Sulawesi Province) Luthfi Muhamad Iqbal; Alvaryan Maulana
Geographica: Science and Education Journal Vol 3, No 2 (2021): December
Publisher : USN Kolaka

What is a city? How can we define the boundaries of a city? Despite being the popular subject of research in rapid urbanization, the discussion of the spatial dimension of urbanization is still few in Indonesia. This paper aims to make the geography of urbanization in Indonesia clearer and easier to understand by applying the degree of urbanization (DEGURBA/DoU) methodology. The case study location proposed is Southeast Sulawesi province (SSP)which has distinctive urbanization trajectories with rapid urbanization trends and a relatively stable rural population, but a lack of research regarding its urbanization patterns. This research used Global Human Settlement Layer (GHSL) data as the primary source to conduct spatial analysis to produce the degree of urbanization with complementary national statistical and spatial data to compare with the current conventional classification methodology. The findings show that based on DoU, 39.87% of the SSP population live in urban centers, 22.58% in urban cluster/periurban, and 37.56%. SSP has a total of 49 urban units with 6 urban centers/cities, and 43 urban clusters/towns. By testing the rank-size distribution of SSP’s urban units, it shows that SSP’s urban systems pattern satisfy Zipf’s law with R2 = .9885, and the slope of the fitted line is -0.9554. Based on this result, currently, SSP has 4 medium cities, 2 small cities, 21 large towns, and 20 small towns. In addition, the DoU also has an opportunity to understand how should urban areas be governed and managed, and by whom. Despite the Greater Kendari Urban Area has not yet fulfilled the national’s Metropolitan population threshold (1 million pop), the urban management and development should be conducted more collaboratively with neighboring regencies such as Konawe and South Konawe. The advantages are shown by these findings highlight the importance of scaling up this research to a national scale and using finer and nationally available data.

The research area is administratively located in the Kabila Bone Sub-district, Bone Bolango District, Gorontalo Province which has an area of 143,51 km2. The purpose of the research is determine landslide susceptibility zonation of Kabila Bone Sub-district , Bone Bolango District, Gorontalo Province. The method used in this research is geological survey method and analysis of geographic information system. The parameters used refers to Peraturan Menteri Pekerjaan Umum No. 22/PRT/M/2007, which includes of slope, soil condition, lithology, rainfall, slope water system, seismicity, and vegetation. The result of research show that Kabila Bone Sub-district consists of a zone with a low level of susceptibility which has an area of 1258,76 ha, a zone with a medium level of susceptibility which has an area of 4026,90 ha, and a zone with a high level of susceptibility which has an area of 502,03 ha. Zones that have a high level of susceptibility are distributed in several villages, namely Botubarani Village with an area of 117,92 ha, Huangobotu Village with an area of 89,35 ha, Bintalahe Village with an area of 64,22 ha, Oluhuta Village with an area of 119,98 ha, and Olele Village with an are of 104,01 ha.

Population and sample study this consist from whole student class X IIS SMA Negeri 1 Tanggetada. Instruments used that is in the form of questionnaire self-efficacy consisting of 34 statements, documentation used for see results study geography student class X IIS. The analysis used in the research is descriptive and inferential. Research results are self-efficacy student Class X IIS SMA Negeri 1 Tanggetada during the COVID-19 Pandemic including in category medium, with students belonging to the category currently totaling 45 students or 50% of sample research. For result data study geography student class X IIS SMA Negeri 1 Tanggetada including in category medium, with students belonging to the category currently totaling 37 people or 42% of sample research. There is influence significant positive self-efficacy student to results study geography student class X IIS SMA Negeri 1 Tanggetada during the COVID- 19 pandemic 2021/2022 lesson, coefficient determinant (r 2 ) of 0.497 or 49.7% which means that the independent variable of self-efficacy has an influence of 49.7% on the learning outcomes of geography.

Probolinggo has the characteristics of the north coast of Java with large mangrove potential. The total area of mangrove forest in Probolinggo is 476.6 ha with a research area of 75 ha covering Pilang, Ketapang, and Pesisir villages. This study aims to estimate the amount of mangrove carbon stock using Normalized Difference Vegetation Index (NDVI) from sentinel-2 data as a vegetation index. A Sampling of data was carried out using a stratified random sampling method and the data collected included trunk diameter, tree height, and mangrove identification using Mongmang software. There were six mangrove species, Rhizophora apiculate, Rhizophora mucronata, Rhizophora stylosa, Avicennia marina, Avicennia alba, and Soneratia alba. The results of the estimated carbon stock are divided into 4 classes from low to high which are marked in green to red. The value of carbon stock ranged from 95.96 tons/ha to 7089.50 tons/ha. The results obtained by Pilang Village have high biomass and carbon stock values marked in red on the map. The results of the accuracy-test using standard error estimation (SE) get a small accuracy result of 10%.
