Abstract

One way of knowing the land coverage change is through Landsat TM imagery analysis from two periods of running time.  It takes at least 2 coverage of the image data to get land cover changes.  Mine concession area of PT Kaltim Prima Coal is a product of the area functional transfer of formely the Forest Cultivation Areas (KBK) ex IUPHHK PT Porodisa Ltd. into Other Areas Use (APL) of PT Kaltim Prima Coal mine concession.  In the span of two concession, it was necessary to know whether there are changes in land cover during the transition period (the period of 10 years).  It can only be known through the analysis of land use change using Landsat TM in 2002 and 1012.  The tendency of quality of land cover change that is known through the analysis of these land cover changes and the significance of cover change, are based on information of how the historical of land cover change occurred.

KERUSAKAN TIPE EKOSISTEM KARST DAN PENGARUHNYA TERHADAP PERUBAHAN IKLIM (SUATU PENDEKATAN TEORI) The Damage of Karst Ecosystem and Its Impact on The Climate Change (a theoretical approach)Benteng. H SihombingFakultas Kehutanan, Universitas MulawarmanSamarinda ABSTRACTKarst ecosystem poses high economic potency however its attention was lack due to to date only pay attentions merely on mineral resource potency, and its conservation measure only focus to some extent on cave. Mean while, karst area owns wider protective function, such as water conservation, state revenue from tourism, mining, bird nest, even it closely relates to the national security issue and state intelligence. Pay an attention on karst ecosystem that covers biotic potency and mineral energy exploration is tought to be far from seriousness meanwhile its tension on this ecosystem tends to be larger, even already comes to the stage of ecology endanger. In relation to the global temperature rise that leads to the climate change, natural karst ecosystem seems pay a big role in reducing carbondioxide through karstifikasi process. Therefore, the karst ecosystem conservation is an urgent agenda.Key words : Karst, Ecosystem, Climate change.
