Minister of Public Works Regulation, concerning Technical Guidelines for Analysis of Physical, Environmental, Economic and Socio-cultural Aspects
The aim of this study is to know the land suitability of housing and settlement development in Nias Regency by utilizing the Geographic Information System. This study considers six physical parameters, that is:slope of land, type of rock, type of soil, rainfall, land use and accessibility. Through analysis of land capability units using weighting techniques for each physical parameter and overlay technique on ArcGis, the location of land suitability for housing and settlement development in Nias Regency will be known, then the results are grouped into 3 (three) classifications, High (H) or very suitable, covering an area of 27,384.25 hectar or 48.35%, Medium (M) or suitable, covering an area of 28,452.15 hectar or 50.24% while a low or unsuitable (L) area of 795.93 hectar or 1.41%.
Keywords: Geographic Information Systems, Spatial, Housing and Settlement
Introduction. One supporting aspect for land use in accordance with its designation is the consideration of basic physical aspects. According to Minister of Public Works Regulation No.20 of 2007 concerning Technical Guidelines for Analysis of Physical, Environmental, Economic and Socio-cultural Aspects, in preparing spatial plans, consideration of basic physical aspects can illustrate the characteristics of the land so that it is known the level of land capability in supporting development including settlement activities [ Most Contribution ].
Since the profileration in 2010, the capital of Nias Regency is still in Gunungsitoli but then the issuance of Government Regulation of the Republic of Indonesia (PP RI) No.30 of 2016 then the location of the capital of Nias Regency transfer from Gunungsitoli to Gido Subdistrict .
With the transfer of the location of the Nias regency capital, it is necessary to have a comprehensive and sustainable regional development plan throughout the Nias Regency due to increased development activities in various fields to meet community needs, such as the construction of residential facilities and infrastructure, road infrastructure, economic and social facilities ( Andrew Tapiwa Kugedera )
Based on the Nias Regency Regional Spatial Plan for 2014-2034, one of the strategies for developing coastal areas in Nias Regency is to develop urban and rural residential by developing urban and rural settlements which in accordance with the physical, socio-cultural and economic characteristics of the community. It should also supported by the provision of settlement facilities and infrastructure, improvement of the quality of settlements by the provision of affordable and habitable housing, accessibility to adequate housing especially the most vulnerable, availability of adequate facilities and meeting living standards.
Objectives of the Study. Analyzing the suitability of land of housing and settlement results of this study with Nias Regency Spatial Plan.
Research Methodology. This research is a descriptive research with quantitative research method. Collection of primary data by conducting surveys and to get existing data on housing and settlement land use in Nias Regency are conducted in the following ways:
1.GPS (Global Position System)
4.Modes o transportation
5.Drone and so forth
Secondary data collection was conducted by an institutional survey of the relevant agencies, namely: the Central Bureau of Statistics (BPS), the Regional Development Planning Agency (Bappeda), the Public Works Agency, the Housing and Settlement Service and other agencies related to this research. Quantitative analysis is used to conduct spatial analysis of housing and settlement development, as well as mathematical models that are relevant to the object of study.
Analysis of scoring land suitability results from scoring in the form of land suitability maps for housing and settlement development with the 2014-2034 Spatial Plan Map of Nias Regency through an overlay process. This is because spatial plan provides recommendations for managing land use for housing and settlements, so an alignment analysis between the results of the study with the Regional Spatial Plan (RTRW) is needed.
Literature Review. According to Law No. 1 of 2011 concerning Housing and Settlements, the definition of Housing and Settlement Area is a unified system consisting of renewal, housing, provision of settlements, maintenance and repair, prevention and quality improvement of slums and slums, land provision, funding and financing systems, as well as community participation. Housing is a collection of houses as part of settlements, both urban and rural, which are equipped with infrastructure, facilities and public utilities as a result of efforts to fulfill habitable homes while settlements are part of the environment outside protected areas, both in the form of urban and rural areas, which serves as a place to live and a place for activities that support life .
According to Sadana , the real difference between settlements and housing lies in its function. In residential areas, the environment has a dual function, namely as a place to live and at the same time a place to make a living for some of its inhabitants. In housing, the environment is only a collection of houses that serve as a place to live. The function of housing is only a place to live, and does not serve as a place to earn a living.
