Geographical Weighted Regression Model for Poverty Analysis in Jambi Province
Get PDFAgriculture sector has an important contribution to food security in Indonesia, but it also huge contribution to the number of poverty, especially in rural area. Studies using a global model might not be sufficient to pinpoint the factors having most impact on poverty due to spatial differences. Therefore, a Geographically Weighted Regression (GWR) was used to analyze the factors influencing the poverty among food crops famers. Jambi Province is selected because have high number of poverty in rural area and the lowest farmer exchange term in Indonesia. The GWR was better than the global model, based on high value of R2, lowers AIC and MSE and Leung test. Location in upland area and road system had more influence to the poverty in the western-southern. Rainfall was significantly influence in eastern. The effect of each factor, however, was not generic, since the parameter estimate might have a positive or negative value
Infrastructural Facility and the Students’ Academic Performance - A Critique
Get PDFAbstract: The paper underscores the infrastructural facility and the student’s academic performance in Adekunle Ajasin University, Akungba Akoko, Ondo State, Nigeria. Thirty questionnaires were administered through a systematic sampling technique in each of the six faculties making a total of 180 questionnaires. The paper has found out a positive relationship between the student’s academic performance, power supply and health facilities. However, the internet facilities and transportation facilities were not adequate, whereas water supply was adequate. A test of the impact of infrastructural facility on the student’s academic performance, using a Chi Square statistical technique revealed a significant value of 177.1 at 0.05 % level. The paper recommends that the existing facilities should be upgraded and significantly improved by the government; urgent attention should be given to the development of the internet facilities and transportation sector of the University. Also, private partnership should be encouraged in the infrastructural development of the University
Geoecology Identification Using Landsat 8 for Spatial Planning in North Sulawesi Coastal
Get PDFAbstract Geoecology is a landscape study combined with the social and environmental aspect. The study aims to identify Geoecology of coastal Manado, North Sulawesi. Identification of coastal Geoecology using Landsat 8 supported by SRTM. Data was collected by field survey and taking aerial photo using UAVs. The field survey was conducted to capture the documentation and in-depth interviews. The research method is the interpretation of remote sensing imagery. Data from image interpretation collaborated with field survey data. The results showed that there are three types of coastal that is sandy, rocky and muddy. The sandy comes from karst hills and volcanoes. The rocky and karst hills come from volcanic material that has the character of a big wave. The muddy affected by the presence of the river that carries materials from structural hills. Geoecology based coastal area management is expected to be instrumental in structuring regional integrated and planned.Key words: Geoecology, Landsat, Coastal, North Sulawes
Change Phenomena of Spatial Physical in the Dynamics of Development in Urban Fringe Area
No full textAbstract The study aims at analyzing change of spatial physical, spatial articulation, spatial structure, social and agglomeration and deagglomeration of function in the dynamics of development in the fringe area of Hertasning-Samata, Makassar City. Spatial physical changes are designated by the presence of new socio-economic functions that drive spatial structure changes, spatial articulation, social changes and agglomeration/deagglomeration of function in the fringe area of Hertasning-Samata. It applies quantitative and qualitative approaches (mixed method). Data is acquired from some sources and community informants living in the fringe area of Hertasning-Samata, Makassar City. Rapid and revolutionary spatial physical changes contribute positively to spatial structure changes, spatial pattern, agglomeration/ deagglomeration of area function. Spatial function change which had been dominated by commercial function becomes the determinant of social changes in the fringe area of Hertasning-Samata. Domination of mastery of reproduction of space by capitalism shows differences in mastery of reproduction of space significantly between space of capitalism and space of pre-capitalism. It sharpens economic stratum, status differences, between space of capitalism and space of pre-capitalism and socio-community classes. The dynamic of spatial physical change causes orientation shift to community activity which had run along dialetic of modernity and rationalization of action in local community.Abstrak Penelitian ini bertujuan untuk menganalisis perubahan fisik spasial, artikulasi spasial, perubahan struktur ruang, perubahan sosial, aglomerasi fungsi dan dis-aglomerasi fungsi dalam dinamika pembangunan kawasan pinggiran Hertasning-Samata Kota Makassar. Perubahan fisik spasial ditandai dengan keberadaan fungsi-fungsi kegiatan sosial-ekonomi baru, mengondisikan perubahan struktur ruang, artikulasi spasial, perubahan sosial dan aglomerasi/dis-aglomerasi fungsi kawasan pinggiran Hertasning-Samata. Penelitian ini menggunakan pendekatan kuantitatif dan kualitatif (mixed method). Data diperoleh dari beberapa sumber dan informan komunitas yang mendiami kawasan pinggiran Hertasning-Samata Kota Makassar. Perubahan fisik spasial yang sangat cepat dan revolusioner berkonstribusi positif terhadap perubahan struktur ruang, pola ruang, aglomerasi/dis-aglomerasi fungsi kawasan. Perubahan fungsi ruang yang didominasi fungsi komersil menjadi determinan perubahan sosial pada kawasan pinggiran Hertasning-Samata. Dominasi penguasaan reproduksi ruang oleh kapitalisme menunjukkan perbedaan penguasaan reproduksi ruang yang sangat signifikan antara ruang kapitalisme dan ruang prakapitalisme, berdampak pada penajaman strata secara ekonomi, perbedaan status, dan kelas-kelas sosial komunitas. Dinamika perubahan fisik spasial menyebabkan pergeseran orientasi kegiatan komunitas yang berjalan sejajar dengan dialektika modernitas dan rasionalisasi tindakan dalam komunitas lokal
Mode Choice of Undergraduates : A Case Study of Lecture Trips in Nigeria.
No full textAbstract Travel behavior and determinants of mode choice of university students in Nigeria are neither well understood nor well represented in literature. This study model is modal choice of undergraduates, using data from students travel survey and logistic regression to determine factors influence modal choice of undergraduate students in Obafemi Awolowo University Ile-Ife, Nigeria. The results indicate that walking dominate modes for on-campus and commercial bus for off-campus students, while motorcycles taxi is used by few of the sample. Mode choices are influenced by a combination of socio-economic and trip factors. A key finding is extent that these variables positively affect the odds of using walk and commercial bus modes especially with reference to student residence: on and off-campus. The results suggest investment in pedestrian infrastructure and development of intermodal transport system as a means of making the university livable and attractive.Abstrak Kebiaasaan perjalanan dan penentu moda dari mahasiswa di Nigeria tidak juga dipahami dengan baik atau dijelaskan dalam literatur. Model penelitian ini adalah pemilihan moda mahasiswa menggunakan data dari survei perjalanan mahasiswa dan regresi logistik untuk menentukan faktor penyebab pilihan moda dari mahasiswa di Universitas Obafemi Awolowo, Ile-Ife, Nigeria. Hasilnya menunjukkan berjalan mendominasi pilihan untuk ke kampus dan kendaraan bus umum untuk mahasiswa di luar kampus, sementara sepeda motor taksi digunakan oleh beberapa sample. Pilihan cara dipengaruhi oleh kombinasi dari sosial-ekonomi dan faktor kunjungan. Inti penelitian adalah luasnya variabel positif mempengaruhi peluang dari berjalan dan kendaraan bus umum terutama rujukan ke asrama mahasiswa, dalam maupun luar kampus. Hasil penelitian menyarankan investasi pada infrastruktur pejalan kaki dan pengembangan dari sistem transportasi antarmoda sebagai sarana membuat universitas layak huni dan menarik
