Abstract

Mangrove ecosystem is one of kind forest that naturally influenced by tides. Mangrove root’s system have capability to hold and capture sediment transported by waves or currents which bring to sedimentation or soil formation arise and become the new land for mangrove vegetation. Tailings from the mining PT. Freeport Indonesia in Tembagapura cusher form of a smooth stone is passed through Aghawagon River, followed Otomona River and deposited in the Regional Deposition Ajkwa (DPA), the possibility of 5-10% of particles remaining Sand Mining (tailings) carried out the most subtle to the Estuary Ajkwa and the Arafura Sea (PT Freeport Indonesia, 1999). Sedimentation due to the flow of the remaining mine sand from the river and taken apart Ajkwa currents, thought to affect an area of mangrove forests that exist around the estuaries in the coastal Mimika. Aim of this study is determining the extent of vegetation change in Mimika coastal mangrove District, Papua during 1998 to 2010 using multitemporal satellite imagery. The study was conducted in November 2010 to May 2011 using 1998’s Landsat TM imagery, Landsat 7 ETM + in 2002, Landsat 7 ETM + in 2006, and Landsat 7 ETM+ 2010, by using descriptive method. The results of this study indicate changes in the extent of mangrove vegetation of the estuary area to Mawati Kamora is varied, ie, in the year 1998 to 2002 has improvement 250.64 ha and 234.91 ha of reduction, in the year 2002 to 2006 has improvement 131.82 ha and 193.37 ha of reduction, in the year 20006 to 2010 experienced a reduction of 175.94 ha and 89.28 ha. Supply of sediment input in the form of tailings or suspected influence on the addition of mangrove vegetation in the Mimika District coastal area of Papua, particularly in the area and Kamora Ajkwa River Estuary, while the reduction of mangrove vegetation in the Coastal area of Timika, Papua, probably caused from to hydrological factors of the currents and waves.

Abstract

Samas beach lagoon is a unique and rare ecosystem, as well as being an area of tourism. One of the great river that empties into the Laguna Samas carry sediment material which will further lead to changes in the shape of land in the area. One impact of the change in shape in the area is the ever-expanding or narrowing of the land caused by the process of sedimentation. Sedimentation process is rapid and continuous this will damage the ecosystem Laguna Samas. To overcome this need to be monitoring the events that lead to environmental degradation. This activity is necessary to obtain accurate data and information and the actual on coastal and marine issues being faced today. The method used in this research is descriptive method, which is a study to create a picture of the situation or event that researched and studied in a limited time and place, to get an idea of the situation or conditions locally. In addition, this study also uses remote sensing techniques (visual interpretation using screen digitalizing techniques and field surveys). The material used in this study are Landsat images. Within 15 years, Laguna Samas and extensive changes shape significantly. Vast changes that have occurred in the lagoon research in the period between 1994 to 2001 had an area of 45.53 ha of erosion and accretion area of 13.58 ha. Changes vast lagoon in 2001 to 2005 was eroded area of 58.86 ha and 36.39 ha area accretion. And extensive changes in the lagoon in 2005 to 2011 had an area of 28.07 ha of erosion and accretion area of 58.38 ha. So, in 1994 until 2005, it had added vast lagoon waters, and in 2005 to 2011 extensive shrinkage or constriction waters. These results were obtained from the Landsat 5 satellite imagery overlay TM in 1994, Landsat 7 ETM 2001, Landsat 7 ETM 2005 and Landsat 7 ETM in 2011.
