Pemetaan Sebaran Daerah Asal Mahasiswa Universitas Negeri Manado Berbasis Sistem Informasi Geografis

The need for information regarding the spatial distribution of the area of origin of students who are currently studying at the Manado State University (UNIMA) is very important because the information built can provide useful input for planning, development, or evaluation. So that the distribution of the areas of origin of students who are studying at UNIMA can be mapped properly, an information system based on Geographical Information Systems (GIS) can be built according to its geographic location. This study aims to create and present information about the spatial distribution of students from UNIMA through GIS. Quantitative type research methods with a spatial analysis approach (spatial analysis) using secondary data. Data analysis techniques through Geographical Information Systems (GIS) to create a digital map of the spatial distribution of student origin using OpenStreetMap and Quantum GIS Zanzibar 3.8.1. The results showed that the spatial distribution of the area from which UNIMA students used GIS, made it easier to present information through digital maps. The information system created can display the distribution data of the student's area of origin, namely the number of students from each province in Indonesia and especially in the form of a distribution map. The largest distribution of student origin came from North Sumatra Province with 1,209, followed by South Sulawesi Province with 893 and North Maluku Province with 650 students.

Sebaran Spasial Eceng Gondok (Echornia Crassipes) di Danau Tondano

The growth of water hyacinth in the waters of Lake Tondano can affect the lake's ecosystem due to its rapid growth and spread. Water hyacinth is a weed that damages the aquatic environment which, if its growth and development are not controlled, will reduce the amount of light entering the waters, evapotranspiration, and reduce the amount of water and can accelerate the process of silting the waters of Lake Tondano. The research objective was to determine the distribution pattern of water hyacinth in Lake Tondano from 2015 to 2020. The research method was descriptive qualitative and spatially analyzed data using geographic information systems. The data used are primary and secondary data, obtained through observation and field surveys and documentation. Based on the results of spatial analysis, it is known that the distribution pattern of water hyacinth in Lake Tondano has increased from 2015 with an area of 465.59 Ha, in 2016 the area was 848 Ha, in 2017 the area was 999,695 and there was a change in area decline, in 2018 the area was 675.87 Ha, and 2019 the area was 366.36 Ha. , and in 2020 the area of water hyacinth will increase to 995,797 hectares. The factors causing the uncontrolled distribution of water hyacinth in the waters of Lake Tondano can be due to the season (climate), sedimentation, or land use. The growth and development of water hyacinths have disrupted various community activities and have an impact on the process of silting the waters of the lake and damaging the beauty of Lake Tondano.

Kemampuan Spatial Thinking Guru Geografi Madrasah Aliyah Sulawesi Utara

Kemampuan berpikir spasial (spatial thinking) sangat diperlukan seorang guru dalam memberikan pemahaman kepada peserta didik guna transfer knowledge yang lebih baik. Penelitian ini didasari latar belakang guru geografi Madrasah Aliyah (MA) Sulawesi Utara yang bukan berasal dari rumpun ilmu geografi. Analisis kemampuan spatial thinking dilakukan dengan menggunakan perangkat lunak yaitu Google Earth dengan materi bahasan peta, Sistem Informasi Geografi dan Penginderaan Jauh yang dirangkum menjadi satu rangkaian kegiatan yang kompleks dalam kegiatan Diklat Teknis Substansial. Hasil penelitian menunjukkan bahwa kemampuan spatial thinking yang masih mengalami kendala berada pada aspek penguasaan penyusunan data dan interpretasi data. Perlu dilakukan pemantapan keterampilan untuk menajamkan spatial thinking seorang guru melalui latihan-latihan maupun kegiatan pelatihan lainnya serta integrasi antara pihak perguruan tinggi dengan MGMP Geografi di Sulawesi Utara untuk mengadakan kegiatan periodik guna menjangkau guru-guru yang bukan bidangnya untuk mengajar mata pelajaran geografi didalam proses pembelajaran.Kata Kunci: Spatial thinking, Sistem Informasi Geografi, Pendidikan, Kompetensi Guru
