Abstract

Application of Remote Sensing and Geographic Information System Methods for Land Using Difference. Land using difference analysis has been done using remote sensing and Geographic Information System (GIS) methods. Identification of land using difference was conducted using map overlaying process of 1990s (digitized scalling 1:50.000) and 1997s land using map (interpreted from Landsat TM (Thematic Mapper) Image 1997) with UTM (Universal Transverse Mercator) coordinate. Image enhancement was done through histogram equalization with supervised classification devided into 7 classes: rice field, settlement, dry field, industry, pond, sport field and bush. Land using difference and river pollution BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand) and TSS (Total Suspended Solid) analysis were done through GIS to get database in spasial link and tabular format. Land using difference was done based on division segment of Kali Surabaya contour as reference. The result shows that there were changes on land using from 1990 until 1997 that rice field reduced by 5.72 %; settlement increased by 15,16 %; dry field increased by 0.54 %; industry increased by 36.67 % and bush reduced by 26.67 %. Water pollution analysis results which was done using multiple linier regression show both BOD (determinant coefficient 56 %) and TSS (determinant coefficient 65 %) are affected by difference in land using, but COD (determinant coefficient 24 %) is not affected.

Abstract

The rapid development of technology and science today has had a complex impact on human life, including in the field of education. The demand for quality human resources who have a good work ethic is increasing. Therefore, education has an important role in improving the quality of human life. This research aims to increase the economic literacy of elementary school (SD) students in facing the era of Society 5.0 where there is greater emphasis that technology and its functions have become part of human life. Method Used: This research uses a literature review study method. This method is systematic, explicit, and reproducible for identifying, evaluating, and synthesizing papers from previous research. The research was carried out through several stages by practitioners and experts, by combining references from research and conceptual articles in reputable national journals taken via Google Scholar and others. Research Results: The research results show that learning economics at the elementary school level can increase students' economic literacy. Teachers can use a variety of teaching efforts tailored to students' abilities to provide an understanding of basic economic concepts. Economic literacy helps students understand daily economic activities and make more rational decisions. Providing an understanding of economic literacy also requires intervention from families and schools.
