Tujuan dilakukan penelitian untuk menganalisis karakteristik sosial ekonomi masyarakat sub DAS Alo terhadap perilaku pemanfaatan fisik lahan. Penelitian dilakukan di kawasan sub DAS Alo yang secara administrasi sebagian besar berada di Kecamatan Tibawa. Data yang digunakan merupakan data sekunder dan primer yang diperoleh berdasarkan analisa survei dan studi literatur. Metode penelitian menggunakan metode analisis kuantitatif dan deskriptif kualitatif yang diguakan untuk memperjelas dan menginterpretasikan perolehan data sebgai hasil lapangan. Hasil penelitian menunjukkan bahwa karakteristik sosial dan ekonomi sangat mempengaruhi prilaku masyarakat dalam pemanfaatan lahan di kawasan Sub DAS Alo. Kondisi sosial mengakibatkan pembukaan lahan yang mampu mengubah bentuk fisik daerah DAS seperti pengalih fungsian lahan perbukitan, hutan dan tepi sungai menjadi kawasan pertanian produktif yang kerap dilakukan oleh masyarakat. Disisi lain hasil penelitian menunjukkan terdapat kesenjangan antara pemanfaatan lahan dengan kondisi ekonomi masyarakat. Terdapat petani penggarap sebesar 39,50% dan petani pemilik sebesar 20,50% berdasarkan total sampel yang diperoleh dalam penelitian dan pendapatan petani terbesar berada di bawah Rp.<1.500.000, berdasarkan penggolongan BPS pendapata n tersebut dikategorikan pada kategori pendapatan rendah. Demikian dapat disimpulkan masyarakat yang mayoritas berprofesi sebagai petani memiliki kemampuan ekonomi yang rendah. Dengan kemampuan ekonomi rendah dapat memicu terjadinya pembukaan lahan yang lebih luas untuk bertujuan meningkatkan pendapatan yang layak.
Reviewing spatial planning is a must in planning and regional development, besides that, it is also to obtain information related to the suitability of the use of space that has been used. Spatial planning assessment can be based on a tendency towards spatial use and based on land use and spatial function. Techniques and kali have been carried out using spatial analysis with the concept of geographic information systems that cannot be separated from the research parameters used. The method used is a mixed method that combines quantitative and qualitative methods. The quantitative method functions to produce numerical data so that it can be interpreted into a narrative, while qualitative methods are used to describe either numerical data, tables, pictures, or maps into useful narrative information based on the results of the research that has been done. The purpose of this study is to see the progress in the implementation of space suitability in the campus environment of the Muhammadiyah University of Gorontalo. The result of the research shows that the campus area can be classified based on the length of space, which includes the appropriate area in the built area of 1,81537 ha, the undeveloped area of 7,23050 ha and the unsuitable area is in the built area of 0.04513 ha. In addition to producing information related to space suitability, the research results also provide recommendations regarding the plan to use campus space as an alternative for future development.
Land use change is one of the factors affecting urban development including urban energy needs. This study analysis the effect of land use and surface temperature on energy system development of Gorontalo city. Gorontalo has a very high solar energy potential but has not been utilized optimally. Land Surface Temperature (LST) mapping is the first step to identify the potential of solar anergy for energy system development in Gorontalo City. Remote sensing technology and geographic information systems are helpful in mapping the spatial distribution of each parameter used. In this research the data used is Landsat 8 for mapping land cover/land use, green area and LST. The results showed that in the dry season the highest surface temperature was in the building area, and the lowest temperature was in the vegetation area. Land use in city of Gorontalo is dominated by high density vegetation (VKT) of 36% of the total area, while built-up area has 26% of the total area. LST was dominant in the wet season of 30-40 °C i.e 50.51% of the area while in dry season wasdominant at 40-50 °C covering 42%. The highest temperature in the city of Gorontalo in both dry and wet season is distributed in Pulubala, Limba U1, and Biawao. These three regions can be a recommendation for the development and utilization of solar energy as an alternative energy source. This research provides insight into land surface temperature and become a recommendation in urban planning and energy policy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
