Abstract

Wampu Watershed is defined as the restored watershed carrying capacity according to Regulation of the Minister of Forestry of the Republic of Indonesia Number P.60 / Menhut-II / 2012. The land use for intensive agriculture is very dominant in Wampu watershed and increase the damage which is now often felt by the public. For that reason, that’s done a research for counting the suspended load that occured in Middle-stream of Wampu Watershed. The research was conducted on May up to September 2014 in Bahorok, Salapian, Kuala, and Selesai, by using survey method with taking sample randomly and continued by calculated of suspended load with United State Beureu Reclamation (USBR) method. Data processing used ArcView GIS 3.3. The results of this research showed that the highest suspended sediment discharged in middle-stream of Wampu watershed is 1.501.227,19 grams/second in Tanjung Lenggang, 324.625,29 grams/second in Empus, and 2.572,58 grams/second in Tanjung Keriahen. Therefore it’s necessary to control by doing an appropriate conservation measures to suppress the larger possibility of sedimentation.

Abstract

DAS Deli merupakan salah satu DAS kritis di propinsi Sumatera Utara yang memerlukan penanganan sebagai lokasi sasaran rehabilitasi. Mata pencaharian sebagian besar penduduk pada lahan dataran tinggi di kawasan hulu DAS Deli adalah bertani. Mereka mengolah lahan pertanian sebesar 82% terutama pada desa-desa di DAS Deli bagian hulu. Keadaan ini menimbulkan kerawanan terhadap erosi dan banjir di daerah hilirnya bila pengelolaan lahan tidak disertai dengan upaya-upaya rehabilitasi lahan dan konservasi tanah dan air. Makalah ini membahas salah satu upaya pengembangan pertanian berkelanjutan berbasis agroekologi yang perlu ditekankan dalam mempertahankan dan meningkatkan produksi pertanian. Penjabarannya mencakup 4 dimensi yaitu dimensi sosial ekonomi, sumberdaya sebagai asset produksi dalam usahatani, peningkatan peranan masyarakat, dan program aksi/implementasi yang realistis. Usaha tani berbasis agroekologi dalam pengelolaan lahan dataran tinggi yang tepat guna dan tepat sasaran dapat memberikan keuntungan ekonomi dan melindungi lahan dan lingkungan secara simultan. Dengan demikian pembangunan pertanian secara berkelanjutan dapat terwujud.
