Abstract

ABSTRACTResearch of Green Open Space Identification is done in Residential of Griya Paniki Indahin the Sub-district Mapanget of Manado City. An important factor in current environmentalproblems is the large number human population. Population growth is a major factor affecting thedevelopment of settlements and the needs of facilities and infrastructure. Green open space isincreasingly into existence and turned into buildings to meets the needs of urban dwellers.This research was conducted to find out the green open space in the Griya Paniki Indah.Standard of Green Open Space requirement is obtained from literature study. Analysis to obtainthe results used in this study is a spatial analysis, that is by using geographic information systemsoftware, that serves to identify the existing Green Open Space. The results obtained that the areaof Green Open Space in Griya Paniki Indah Resident is 29.31 hectares or 16.95% of the total areaaccordance with applicable law. Based on this it is necessary to develop Green Open Space suchas green line/path or like city park and green environment and the return of natural green functionin the form of protected area.Keywords : Green Open Space, Griya Paniki Indah, Geographic Information System

Abstract

Sub watershed of Latoma has to be considered as an area of the important regions in South East Sulawesi, because it takes a great responsibility as a water supplier in Konaweha watershed. Konaweha watershed is a source of irrigation and domestic water for Kolaka Regency, Konawe Regency, South Konawe Regency and Kendari Municipality which has been recently in a critical condition. For this reason, it should be well managed. This study was implemented with the aim of establishing model of land use in Latoma sub watershed that can preserve the land and water resources. The method employs a system analysis with simulation technique by using the Run-off Curve Number (CN) model based on Geographical Information Systems (GIS). The result of the research revealed that the run-off curve number is 70,34. It showed that maximum potential water retention or infiltration rate is 107,10 mm. Restructuring of land use pattern should be done to improve the condition of the area to achieve a sustainability objectives. Keywords : Watershed, land use, run-off curve number (CN), GIS

ABSTRACT This study aims to create an application of geospatial information on irrigation networks in Popontolen Village that supports the online monitoring and maintenance of irrigation networks based on WebGIS. This information system can be built using computers with low specifications and is supported by easy and free software (open source). This WebGIS design utilizes the framework of QGIS and the Bootstrap framework for the overall appearance of WebGIS, both of which have a programming language for displaying WebGIS. By utilizing free hosting services that are available, this WebGIS prototype can be accessed by internet users by typing the URL in the address bar https://sijaripopontolen.000webhostapp.com/index.html.
