Abstract

The research aims to develop applications AR4 models as a new model in the extraction of the object area in the medium resolution Landsat 8 image in providing land mapping database for the purposes of planning, evaluation and monitoring of the type of use / land cover. Descriptive method was used to assess the value of the object land spectral on based spectral bands Landsat 8 image transformation results. Image transformation using AR4 models, namely a multiband image analysis model developed by Akhbar et.al., in 2013 using Landsat 7 ETM+ and SPOT 5 XS. Research is now put through trials on the AR4 models Landsat 8 image in the same location as a previous study, in the district (Sigi, Donggala, Parigi Moutong) and Palu City with an area of 99,141.12 hectares. Geographically, located at coordinates 119 ° 48 '39.67 "E - 120 ° 1' 2.99" E and 0 ° 42 '5.11" S - 1 ° 5' 15.76" S. Generated imagery Landsat 8 AR4 models with the conformity / suitability of land ≥90% between objects on the image of the transformation and the 50 sample sites tested in the field. So that the AR4 models image of Landsat 8 including the excellent category is used in mapping the type of use / land cover.

Abstract

The participation is involvement society as active that is considered as one of the key for the approach that very promise in management forest production in development forest plants program. The government have to eforts the construction forest plants either in the forest area or in area the society property, that is more emphasize for the society participation aspect in it. The research purpose to know the society participation level and the elements relation that influence the society participation for the forest production management in development forest plants program. This research is done for three month begin april until june 2016. The location of research in sigimpu village in palolo subdistrict sigi regency.The method is used in this research, used spearmank rank correlation test. The result of this research that the society participation level for planning phase in development forest plants activity is low while for implementation phase is high. The factors infivence the participation of society for the forest plant development seen by age, education level and income level. The relation between factors influence the participation of society for every phase of development of forest plants activity, that is age factor with every phase of development of forest plants is valueable positive that pointed out of the same direction system, education level is pointed out of the same direction system too. For planning and implementation phase is pointed out of the same direction system, too.

Abstract

This study aims to determine the area-level greenness of mangrove ecosystems in Balinggi Sub-district, Parigi Moutong Regency, Central Sulawesi, by using Landsat 8 image data. It is expected to provide information about the normalized difference Vegetation Index (NDVI) of each site that has been analyzed using GIS. The observation was conducted in June –August 2017. The research method used in this study was by assessing the mangrove density or the level of greenness using the vegetation index method through the NDVI formula, which is effective as an initial division of vegetation areas. The NDVI can be an indicator to measure green leaf biomass and leaf area index for the classification of vegetation. Based on the results of Landsat 8 image data of 2016, the total area of mangrove forest vegetation in Balinggi was 163.30 ha and can be classified into three classes of vegetation density, namely: low (26.46 ha), moderate (55.54 ha) and high (80.08 ha). Furthermore, based on the table of Landsat image classification, the low density class has “very good” land use accuracy with a value of 100% while the high and moderate density classes have “good” land use accuracy of 75% and 67%, respectively.

Abstract

Palu City is the Capital of Central Sulawesi Province, which is also the center of a variety of activities and services for both residents within the city and other areas outside or around the City. Activities and services of the population have resulted in the city of Palu experiencing very rapid development. The rapid growth of settlements and development in the city of Palu will have a significant influence on land use change. Changes in land use that are not in accordance with the rules of spatial planning can result in decreased environmental quality, environmental degradation / environmental damage and reduced natural resources. The declining quality of the environment is due to the increasingly spatial allocation of space for urban vegetation. The purpose of this study was to determine the level of air temperature distribution in Ulujadi District based on Landsat 8 imagery and determine the level of vegetation density based on air temperature. This research was conducted for 3 months from February to May 2016. Analysis of air temperature using band 11 to analyze the distribution of air temperature by comparing the vegetation density analysis of NDVI (Nomalized Difference Vegetation Index) using band 5 (NIR) and band 4 ( Red) on Landsat 8 imagery to determine the effect of vegetation absorption on air temperature by using ArcGIS software version 10.2. Based on the analysis of air temperature using Landsat 8 imagery, it can be concluded that the distribution of air temperatures in Ulujadi District ranged from 18.89 - 25.890C with an area of 1954.48 Ha (31%), 25.90 - 32.890C with an area of 2.198 , 67 Ha (35%), and the highest temperature distribution in Ulujadi District reached 2,213.83 Ha (35%) with an air temperature level of 32.90 - 39.890C. The level of vegetation density in Ulujadi Subdistrict is divided into three with a vegetation index value of -0.19 - 0.25 sparse density, with a distribution area of 1,381.79 Ha (22%), moderate density 0.25 - 0.35 medium density with the distribution area is 965.57 Ha (15%), the density of the meeting is 0.35 - 0.60 with a distribution area of 4.018.80 Ha (63%) from the area of Ulujadi Subdistrict.
