ABSTRAK
DAS Semangka di Provinsi Lampung memiliki potensi pengatur tata air, penyedia oksigen, dan cadangan karbon pada dua wilayah konservasi di dalamnya yaitu Taman Nasional dan Hutan Lindung. Potensi cadangan karbon berkurang dipengaruhi deforestasi pada wilayah konservasi. Oleh karena itu penelitian ini penting untuk mengetahui secara spasial dan temporal deforestasi dan cadangan karbon. Perhitungan cadangan karbon dan overlay klasifikasi tutupan lahan dengan Citra Landsat digunakan untuk analisis deforestasi serta penurunan cadangan karbon di wilayah konservasi dalam periode 1996 ndash; 2016. Penurunan cadangan karbon teritinggi DAS Semangka periode 1996 ndash; 2016 pada ketinggian 1.001-1.500 mdpl dan kelerengan 0-2 dengan penurunan cadangan karbon 26 jutaton.

ABSTRACT
Semangka Watershed in Lampung Province has potential as regulate water, oxygen providers, and carbon stocks in two conservation areas which are National Park and Protected Forest. The potential for carbon stocks had reduced due to deforestation in conservation areas. Therefore, this research was important to know deforestation and carbon stocks spatially and temporally. The calculation of carbon stocks and overlay of land cover classification with Landsat Imagery was used for deforestation analysis as well as decrease of carbon stock in conservation area from period 1996 ndash 2016. The highest decrease of carbon stocks in Semangka Watershed at an altitude of 1.001 1.500 masl and slopes 0 2 was 26 million carbon stock decrease in the period from 1996 2016.

Kawasan konservasi suatu Taman Nasional merupakan zona konservasi yang harus dikelola berdasarkan sistem zoning menurut Undang-Undang No.5 Tahun 1990 dan ketentuan Internasional yang telah dideklarasikan pada The IVth World Congress on National Park and Protected Area di Caracas, Venezuela 1992. Taman Nasional Ujung Kulon telah ditetapkan sebagai Warisan Alam Dunia oleh Badan Intemasional UNESCO (1992) dan terdaftar pada Buku Merah International Union for Conservation of Nature and Natural Resources 1 IUCN (1994) karena merupakan kawasan konservasi bagi habitat terakhir Badak Jawa (Rhinoceros sondaicus) di dunia yang dikategorikan langka. Analisis Kesenjangan merupakan suatu pendekatan spasial yang digunakan untuk mengetahui secara dimensi keruangan tingkat keakuratan dari keberadaan suatu spesies dengan komunitas alamnya dalam suatu kawasan yang dikonservasi dengan menggunakan metode penggabungan antara teknik remote sensing, teknik sistem informasi geografis dan metode skala pengharkatan. Penelitian dengan judul " Analisis Kesenjangan Zonasi Pengelolaan Taman Nasional Ujung Kulon Berdasarkan Sebaran Badak Jawa (Rhinoceros sondaicus) " ini bertujuan untuk mengkaji kesenjangan yang terjadi terhadap zonasi pengelolaan kawasan konservasi Taman Nasional Ujung Kulon berdasarkan pendekatan biogeografi dan pertimbangan biogeofisik. Sasaran yang ingin dicapai melalui pendekatan analisis kesenjangan ini adalah mengetahui distribusi spasial zona sensitifitas, distribusi wilayah kesesuaian habitat Badak Jawa (Rhinoceros sondaicus), dan mengetahui besaran kesenjangan yang terjadi antara wilayah kesesuaian habitat Badak Jawa (Rhinoceros sondaicus) dan zona sangat sensitif terhadap zona pengelolaan kawasan konservasi Taman Nasional Ujung Kulon PHPA. Hasil penelitian ini menunjukkan bahwa diperoleh zona sensilifitas untuk kelas sangat sensitif seluas 8.608 ha, wilayah kesesuaian habitat Badak Jawa (Rhinoceros sondaicus) seluas 3.734 ha. Kesenjangan terjadi sebesar 33,22% atas zona konservasi sangat sensitif dan wilayah kesesuaian Badak Jawa (Rhinoceros sondaicus) terhadap zona pengelolaan kawasan konservasi Taman Nasional Ujungkulon I PHPA. ...... National Parks as nature conservations are defined as areas having natural ecosystems which are managed through zoning systems. These systems are based on the 1990 Act 5 and international regulation and was declared by the IVth World Congress on National Parks and Protected Areas which was held in Caracas, Venezuela, 1992. Ujung Kulon National Park was declared a World Heritage Site by UNESCO (1992) and registered by The International Union for Conservation of Nature and Natural Resources 1 IUCN Red List Categories (1994) as the last habitat for the "Endangered" Javan Rhinoceros (Rhinoceros sondaicus). Gap Analysis is a spatial approach of identifying the accuracy of spatial dimension of community species in natural conservation areas. As a spatial approach, Gap Analysis presents a combined methodology provided by Remote Sensing, Geographic Information Systems and Leopold Interaction Matrix Methodology. The purpose for the study of " Gap Analysis in The Zoning Management System of Ujung Kulon National Park Indicated by Java Rhinoceros(Rhinoceros sondaicus) " was to seek the gap occurring between the zoning management system of Ujung Kulon National Park and a system based on the biogeographically approach and biophysical geography consideration. The aim of the Gap Analysis approach was to find the ecosystem spatial distribution of Taman Nasional Ujung Kulon by (1) providing the spatial distribution of the sensitive zoning conservation area in Taman Nasional Ujung Kulon, (2) providing the habitat suitability for the Java Rhinoceros (Rhinoceros sondaicus) and (3) to seek the gap width between the sensitive extremely area plus the area of habitat suitability for the Java Rhinoceros (Rhinoceros sondaicus) and the areas defined by the zoning management system of PHPA. The results of the study indicated the sensitive extremely zoning conservation area is 8.608 ha, the habitat suitability for the Java Rhinoceros (Rhinoceros sondaicus) is 3.734 ha thus a 33,22 % gap occurred between the sensitive extremely area plus the areas of habitat suitability for Java Rhinoceros (Rhinoceros sondaicus) and the area to those defined by the zoning management system of PHPA
