Variations on The Concentration and Purity of Oil Palm Flowers (Elais guineensis Jac.) in Some Extraction Methods for Identification of the Flowering Gene
Palm oil production is related to the number of fruit and is thought to be determined since the beginning of the flowering phase as the initial stage of fruit formation. Identification of oil palm flowing genes needs to be done as the first step of knowing the mechanism of flowering in oil palm molecular. Oil male and palm females contain high polysaccharides and polyphenolic compounds so they can inhibit the process of molecular identification. Molecular studies provide accurate and fast information about the potential of oil palm genetics as a commercial commercial commodity. The purity and concentration of DNA and the temperature of annealing are the main requirements for PCR-based molecular studies. The purpose of this study obtained the extraction method of oil palm flowers which produced high DNA concentration and purity and optimized the temperature of annealing to identify the flowering gene. DNA from male flower spike and female flowers is extracted using the A (SDS) method, method B (CTAB), method C (CTAB + PVP), and method D (commercial kit). Primary BMS annealing temperature for amplification of optimized flowering genes using PCR gradients. The extraction of male flowers and female flowers using the C (CTAB + PVP) method produces the best DNA concentration and purity compared to other methods. The best annealing temperature for male flower DNA amplification and female flowers using the BMS primer is 61.1 o C. Amplification of male flowers and female flowers using Primary BMS produces 1200 PB products. The results of DNA extraction and PCR amplification using the BMS primers in female flower samples are better than male flower

Demystifying the Geography of Urbanization in Indonesia (Case Study: Southeast Sulawesi Province)
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
