[ABSTRAK
Studi ini mengeksplorasi tentang pengelolaan kawasan agropolitan Selupu Rejang di Kabupaten Rejang Lebong, Provinsi Bengkulu. Provinsi Bengkulu yang telah ditetapkan sebagai kawasan rintisan pengembangan agropolitan sejak tahun 2002 yaitu di kawasan agropolitan Selupu Rejang, masih belum mencapai sasaran idealnya. Tekanan yang timbul akibat aktivitas budidaya yang intensif terutama di daerah pertanian dataran tinggi, menyebabkan kawasan menjadi tidak berkelanjutan. Data menunjukkan bahwa telah terjadi degradasi lingkungan di kawasan agropolitan Selupu Rejang akibat aktivitas pertanian yang tidak sesuai dengan kaidah ekologi di kawasan tersebut. Kondisi lingkungan yang terdegradasi tersebut dapat menyebabkan kawasan agropolitan menjadi tidak berkelanjutan, apalagi kawasan tersebut adalah dataran tinggi yang mempunyai peran penting untuk kestabilan ekosistem. Oleh karena itu, studi ini bertujuan untuk menganalisis kondisi eksisting, menganalisis status keberlanjutan, serta membangun model pengelolaan kawasan agropolitan berkelanjutan yang mengintegrasikan kepentingan ekonomi, sosial, dan lingkungan. Kawasan agropolitan dapat berkelanjutan jika mengintegrasikan aspek lingkungan yang sesuai dengan ekosistem Indonesia, yaitu ekosistem hutan hujan tropis. Analisis menggunakan analisis deskriptif, analisis spasial. Rap-Agrotropika, dan system dynamics. Hasil adalah model tersebut dapat menurunkan degradasi lingkungan dan secara simultan juga dapat meningkatkan produksi serta nilai tambah sektor pertanian, sehingga keberlanjutan sistem produksi pertanian, keberlanjutan ekonomi perdesaan, dan keberlanjutan lingkungan dapat dipertahankan dan ditingkatkan.;

ABSTRACT
This study explores the management of Selupu Rejang agropolitan area in Rejang Lebong regency, Bengkulu Province. Bengkulu Province has been designated as pilot area of agropolitan development since 2002. Selupu Rejang agropolitan was the one of agropolitan area which still has not reached the ideal target. Pressure on the environment was arising as a result of intensive farming activities, especially in the highland agricultural areas, causing the area becomes unsustainable. The data reveal that there has been environmental degradation in Selupu Rejang agropolitan due to agricultural activities. It is not in accordance with the principles of ecology in the region. Degraded environmental conditions can cause agropolitan become unsustainable, especially in the upland area that has an important role for the stability of ecosystem. Therefore, this study aims to build agropolitan area management model that integrates economic, social, and environment interests. Hence, the agropolitan development can be sustained by entering the interests of the environment in the development of the region in accordance with the rules of typical ecosystems in Indonesia, called the tropical rainforest ecosystem. This study uses descriptive analysis, spatial analysis, Rap- Agrotropika, and system dynamics. The result is a model that can reduce environmental degradation. It can also simultaneously increase production and add value to the agricultural sector. Finally, the sustainability of agricultural production systems, rural economy, and environment can be maintained and improved., This study explores the management of Selupu Rejang agropolitan area in Rejang Lebong regency, Bengkulu Province.

ABSTRACT
Ekosistem daratan di Banggai Kepulauan Bangkep memiliki karakteristik khas hutan tropis Sulawesi. Perambahan kayu, perburuan dan aktivitas agraris masyarakat mendorong terjadinya degradasi pada hutan tropis Bangkep dari waktu ke waktu. Pemulihan fungsi ekosistem dapat dicapai dengan upaya restorasi ekologi. Penelitian ini bertujuan untuk menganalisis tingkat degradasi hutan dan membangun model spasial restorasi yang sesuai. Tingkat degradasi ditentukan berdasarkan perubahan luas tutupan vegetasi dan keberadaan spesies asli. Perubahan tutupan vegetasi dianalisis secara temporal pada periode 1991 dan 2014 berdasarkan nilai Enhanced Vegetation Index EVI pada citra Landsat 4 TM dan Landsat 8 OLI, dilengkapi dengan analisis deteksi perubahan dan ground truth. Hasil analisis regresi logistik menghasilkan bahwa kejadian degradasi dipengaruhi secara signifikan oleh variabel ketinggian wilayah, jarak hutan dari jalan dan permukiman. Hutan terdegradasi ringan memiliki porsi luas sebesar 24 , hutan terdegrdasi sedang seluas 28 dan hutan terdegradasi berat seluas 48 . Pola degradasi hutan semakin berkurang seiring dengan bertambahnya ketinggian wilayah. Jenis restorasi yang sesuai untuk hutan terdegradasi ringan adalah dengan assisted natural regeneration ANR yang sesuai diterapkan pada wilayah elevasi tinggi. Hutan terdegradasi sedang dapat dipulihkan dengan pengkayaan pohon-pohon asli serta spesies non-asli tertentu. Pada hutan terdegradasi berat dapat diterapkan agroforestri sebagai sistem perkebunan berkelanjutan. Pohon yang dapat hidup dengan baik umumnya berasal dari pembibitan lokal karena memiliki komponen abiotik suhu, kelembababan, iklim yang sama dengan wilayah penanaman.

ABSTRACT
Banggai Kepulauan Bangkep has a unique terrestrial ecosystem type of Sulawesi tropical rainforest. Timber harvesting, animal hunting and shifting agriculture are regarded as the main cause of forest degradation over time. Ecological restoration is needed to restore ecosytem functions. The objectives of this study are to analyze forest degradation rate and build suitably spatial restoration model. Degradation rate is determined by vegetation cover change between 1991 and 2014 based on Enhanced Vegetation Index EVI from Landsat 4 TM and Landsat 8 OLI, completed by change detection analysis and ground truth. Logistic regression analysis revealed that degradation event significantly influenced by altitude, distance from road and settlements. Low degraded forest is covering 24 area, medium degraded forest 28 and 48 area is high degraded. The forest degradation decrease due to increasing altitude. The appropriate type of restoration for low degraded forests is assisted natural regeneration ANR , which suitable for region with high altitude. Enrichment planting with native and selected non native trees could applicated in medium degraded area. High degraded forest can be restored by agroforestry as a sustainable agriculture system. Local seedling results a good growth of trees, because it has similar important abiotic factors such as temperature, humidity and climate.
