Abstract
Agriculture is a business issue that has long existed and will likely continue to exist throughout the ages. Similarly, on the issue of agricultural land use chrysanthemum that needs to be developed method of analysis using technology approach and computer science. This research intends to analyze and develop effective and efficient methods of chrysanthemum land use. The satellite imagery data covering pre-processing, processing and post processing in this research is mostly done with QGIS software. Satelite image used in this research is LANDSAT 8 OLI and band used are band 6, bang 5, band 2 and band 8. Stages of working this research include image cutting in the research area of all bands and all temporal images involved in research, pansharpening using "Orfeo toolbox", image classification with "semi-automatic clasification", then completed with analysis of land use change using "molusce". The result of this research is spatio-temporal data of two images of land use chrysanthemum in April 2017 and August 2017. The result of mathematical research is a statistical table of changes of agricultural land use on two temporal of image used as research object. In addition to the two results of the analysis data, this study also describes the digital image analysis method of agricultural land use chrysanthemum which is expected to be useful for remote sensing research on other research object or extension to this research.
Highlights
Agriculture products are an important commodity that naturally will continues to experience the development
An analysis of agricultural land use shows a decrease in agricultural land area in the area studied in the period April 2017 to August 2017
The results of this study show the same trend with the data of BPS which shows the decrease of annual land area
Summary
Agriculture products are an important commodity that naturally will continues to experience the development. On the basis of this, the research team conducted a study on the analysis of agricultural land use of chrysanthemum flowers in a region that represents a large amount of chrysanthemum farming In this case the researcher specifies the area of Bandungan Subdistrict, Semarang Regency, Central Java Province which is one of the regions with the highest chrysanthemum flower production in Indonesia [14,16,17], as the area to be the object of research. This research is expected to be a valid and useful informant reference for farmers, traders, government and other stakeholders in taking strategies and policies in chrysanthemum agribusiness related to land use in the area under study This land use analysis research is expected to produce a digital geographic information product that is valid, easy to develop, easy to use and easy to distribute in order to improve the effectiveness and efficiency of its utilization [10], both in terms of production and marketing of agricultural products, especially chrysanthemum flowers. The chrysanthemum floral analysis method that is produced in this research is expected to be utilized in wider research area or applied to other research object related to digital image analysis
