Abstract

Indonesia is one of the archipelagic countries in the world that has two-thirds of its territory is water and is located in a strategic location because it is at the crossroads of world trade routes, in addition Indonesia also has a wide variety of ethnic groups scattered throughout Indonesia. So the need for a port is very important for every area and city in Indonesia. However, many ports built in Indonesia pay little attention to the location where the port will be built. So the ports in Indonesian waters are not long enough. To overcome the problem a computer system in the form of a decision support system determining the location of port construction is required. This study aims to build a system for decision support in determining the location of coastal port construction. The method used was AHP by comparing the parameters present at each port location. parameters include, Soil, Access, Hinterland, Land, Waves and Structure of the soil. So that the port to be built can work properly.

Abstract

This study examined the effect of using Google Earth as an instructional medium on elementary students’ spatial ability in IPAS (Integrated Science and Social Studies) learning focused on spatial concepts. A quantitative quasi-experimental method with a nonequivalent control group pretest–posttest design was employed. The sample comprised 52 sixth-grade students: an experimental class from SD Negeri 4 Palu (n=29) and a control class from SD Negeri 20 Palu (n=23). The intervention lasted four sessions using structured exploration activities with Google Earth supported by worksheets, while the control group learned with conventional media (static maps/pictures). Spatial ability was measured using a 35-item test (25 multiple-choice and 10 open-ended items) converted to a 0–100 scale. Data were analyzed descriptively, followed by gain/N-gain computation, an independent-samples t test at α=0.05, and effect size estimation using Cohen’s d. Results indicated a significant difference in improvement between groups (p = 0.000019) with a large effect (Cohen’s d = 1.20). The largest gains were observed in distance–direction–location relations and 2D–3D transformation skills. These findings suggest that Google Earth is an effective interactive visual medium to enhance elementary students’ spatial understanding in IPAS learning
