This study aimed to develop land use scenarios in District Mapanget using Agroecology Zone-based Geographic Information System (GIS). The data used in this study are primary data and secondary data. Primary data were collected through surveys and direct observations in the field. The activities carried out field surveys to obtain state information field through taking pictures with a digital camera. Analysis of social data and data on potential farming is also done through the compilation of data to map the District Mapanget. Furthermore biophysical data agro-ecological, social and agricultural potential of the data compiled in a database system was using Quantum GIS program version 1.8. This study found that the use of agricultural land to non-agricultural land in the district Mapanget very difficult to avoid due to the low value of land from the agricultural sector compared to other sectors. So based on the evaluation conducted by comparing the map with a map of the existing condition of the District RTRW 2014-2034 Mapanget then it changes the function of which is no longer appropriate region where the agricultural area have been converted into non-agricultural. In order for this condition continues to be bad for the environment and agriculture will require efforts in the management and development in the District Mapanget, among others, the development of urban agriculture, every development in Sub Mapanget should always refer to the scenario Land use and Spatial plan of the District Mapanget that there are both carried out by the government, private or public. Urban agriculture has an important role for urban communities that suggested the need for land use scenarios in District Mapanget. Based on agroecological zone map and a map of the District RTRW 2014-2034 Mapanget then be collated Mapanget the District land use scenarios are divided by 3 (three) scenarios that city Scenario, Scenario frame the city, urban-rural scenario. The existence of land / space urban agriculture plays an important role in agricultural production systems and maintain the quality of the environment, because it is a major determinant spacious RTH (green open space) and the results of urban agriculture. In addition, urban farming provides employment and a source of additional revenue as well as environmentally sustainable society.

The research objective was to determine the suitability of land for a certain class of agricultural crops, namely, vanilla, oil palm, coconut, cocoa, nutmeg and cloves and to determine the direction of the crop land use. The study used survey method and analysis is to compare with criteria data suitability of land for plantation crops. Based on the results obtained twenty eight overlay land units and land units nineteen taken as a sample. The results show the suitability of land in Bacan Island of South Halmahera District for commodity crop plantations vanilla, oil palm, coconut, nutmeg and cloves in a class of land suitability is quite suitable (S2), cocoa belongs to a class of land suitability is marginally suitable (S3) with limiting factor the relative humidity. Economic analysis for all commodities is very suitable for development and Bacan Island of South Halmahera Regency.

This study aimed to analyze the effect of land cover types to micro-climate of and analyze the effect microclimate to the trees and open land towards amenities environment for human. The City of Bitung has selected as a research site because it planned for mega projects. They are Special Economic Zones (KEK), International Relations Ports and Manado-Bitung Highways. The research used primary and secondary data. The parameters measured for each land cover includes the elements of microclimate namely: Air Temperature, Humidity and Solar Radiation. Data analysis using techniques T test, F test and Analysis of amenities based on the data of air temperature and humidity, it can be calculated by Temperature Humadity Index (THI). The measurement results microclimate taken at four different land cover that is at the city park, Central Business District (CBD), housing and industry. The results of this study prove the hypothesis that there are differences in the average value of the temperature and humidity in the trees, open land. Tree vegetation structures more effectively reduce the air temperature. The structure of the vegetation canopy of trees that have rounded and more densely branched patterns, height being between 6-10 m and serves to overshadow proved more effective in improving amenities in the surrounding area. Based on the value of THI, all land cover both parks, CBD, residential and industrial categorized uncomfortable because the average is at a value> 27. Housing area has very little green space. One of the efforts to improve the quality of the microclimate in order to enhance the user experience is to provide a good environment garden by planting vegetation predominant tree combined with shrubs and grasses to balance and harmonize between buildings and the environment also have aesthetic value. In the industrial area, the high levels of air pollution resulting from the production process so that recommended a good landscape arrangement, by expanding area of town forest and planting vegetation of trees that can absorb large numbers of pollutants result in healthy and fresh air for the region.

PEMANFAATAN LAHAN DI KECAMATAN RATAHAN, KECAMATAN RATAHAN TIMUR DAN KECAMATAN PASAN KABUPATEN MINAHASA TENGGARA BERDASARKAN ZONA AGROEKOLOGI DENGAN MENGGUNAKAN SISTEM INFORMASI GEOGRAFIS Astri Vandalia Elisabeth Naray; Johan Alexander Rombang; Jaelani ., Husain

This study aims to determine the direction of land use in Ratahan Subdistrict, Ratahan Timur and Pasan, SoutheastÂ Minahasa Regency, based on the Agroecology Zone using the application of Geographic Information Systems (GIS). The type ofÂ research used in this study is quantitative research with a method of data and spatial interpretation. The types of data used in theÂ study are primary data and secondary data. The data generated is arranged in the form of information and spatial. The studyÂ was conducted in 3 (three) subdistricts namely Ratahan Subdistrict, Ratahan Timur Subdistrict and Pasan Subdistrict, SoutheastÂ Minahasa Regency, North Sulawesi Province, which were included in 1 (one) sub-district, Ratahan Sub-district. While theÂ implementation time in April to June 2018. Analysis of the data used in this study where the resulting data is arranged in theÂ form of data and spatial information, then compiling and analyzing data using the Quantum ArcGIS version 10.2 programÂ application. Besides that, biophysical data analysis and agricultural potential data will be carried out. The results of the studyÂ based on the concept of land use in Ratahan Subdistrict, East Ratahan and Pasan results of agroecological zone maps using GISÂ obtained 32 zones from the results of analysis of soil type and slope data and climate type. The results of the analysis of theÂ allocation in accordance with the conditions of land use (land cover) as well as the output of the map of Southeast MinahasaÂ Regency RTRW space map in 2013, the agroecological zone can be divided into two main uses, namely protected zone andÂ cultivation zone. In protected areas recommended in protected forests, water catchment areas, river borders and lake bordersaround the springs. Whereas in the cultivation area it is recommended to use land for agroforesty, rice fields, settlements, mixedÂ farming, conservation settlements, plantations and production forest.*eprm*
