Abstract

The increasing volcanic activity of Anak Krakatau volcano has raised concerns about a major disaster in the area around the Sunda Strait. The objective of the research is to fuse Landsat-8 OLI (Operational Land Imager) and Sentinel-1 TOPS (Terrain Observation with Progressive Scans), an integration of SAR and optic remote sensing data, in observing the lava flow deposits resulted from Anak Krakatau eruption during the middle 2018 eruption. RGBI and the Brovey transformation were conducted to merge (fuse) the optical and SAR data.  The results showed that optical and SAR data fusion sharpened the appearance of volcano morphology and lava flow deposits. The regions are often constrained by cloud cover and volcanic ash, which occurs at the time of the volcanic eruption.  The RGBI-VV and Brovey RGB-VV methods provide better display quality results in revealing the morphology of volcanic cone and lava deposits. The entire slopes of Anak Krakatau Volcano, with a radius of about 1 km from the crater is an area prone to incandescent lava and pyroclastic falls. The direction of the lava flow has the potential to spread in all directions. The fusion method of optical Landsat-8 and Sentinel-1 SAR data can be used continuously in monitoring the activity of Anak Krakatau volcano and other volcanoes in Indonesia both in cloudy and clear weather conditions.

Abstract

Kubu Raya district is a district of the division of Pontianak regency formed by Act 35 of 2007 concerning the Establishment of Kubu Raya district with an area of 6985.20 km ² ( 698,520 acres ) . There are 342.984 ha of peat land area comprising 171 396 ha of shallow peat , peat in the 49 621 ha , 38.953 ha of peat medium , peat in the 83 014 ha while the development activities for oil palm plantations of business licenses obtained has reached an area of about 206 154 ha consisting of 23 fruit companies mostly scattered on peatlands , related to the use of peatlands for oil palm cultivation requires prudence and careful planning with a record of environmental damage . The concept of the development of oil palm plantations on peat land must be in accordance with the  rules  of  Regulation  of  the  Minister  of  Agriculture  of  the  Republic  of  Indonesia  Number14/Permentan/PL 110/2/2009 on Guidelines for Aquaculture Lowland Sustainable Palm Oil which aims to develop the cultivation of oil palm plantations , preserve the function of land peat , increase production and revenue produksen palm .. To understand these activities , then made the purpose of the study : 1 . Identify and analyze the factors that influence the development strategy of oil palm plantations on peat land in Kubu Raya District .2 . Formulate strategies alternanif development of oil palm plantations on peatland Kubu Raya district .The method used was a survey method and included in the descriptive study . The sampling technique used was purposive sampling method , which determines directly or by deliberately selecting respondents . To know the strengths , opportunities , weaknesses and threats of the development of oil palm plantations on peatland Kubu Raya district , then do a SWOT analysis ( Strengths Weakness Opportunities Threath ) . From the analysis it turned out SO strategy ( Strengths Opportunities) ( 3.3743 ) is the best strategy in the development of oil palm plantations on peatland Kubu Raya district , while the strategy is as follows: 1 ) Planting Area Improvement Strategy and Increased Production of oil palm plantations  peatlands  .  2  )  Increased  and  improved  palm  oil  products  according  to  standard  .
