Abstract

Watershed is a unity of ecosystem from upstream to downstream consisting of the main elements of soil, vegetation, water, and air. Watershed has an important function in sustainable community economic development.  Changes in land use result in most of the rainwater flowing as surface water which directly or indirectly has caused land degradation. This study aims to identify the presence of high conservation value areas as providers of natural environmental services in the Krueng Peusangan watershed. This study used the HCV Toolkit Indonesia approach and SIG analysis with a tiered quantitative method of slope, soil type, land cover and averaged daily rainfall intensity. The results obtained showed that the Krueng Peusangan watershed has 40.54% of high conservation value areas as providers of natural environmental services, with 23.15% of water supply and flood control areas and 20.01% of erosion and sedimentation control areas. It also identified, 2.67% of the Krueng Peusangan watershed is water supply and flood control areas as well as erosion and sedimentation control areas. This research offers important information about areas providing natural environmental services to the central government, local governments, non-governmental organizations and communities to work together to answer the big challenges in managing the Krueng Peusangan watershed

Nasrul Arahman; Born in Tringgadeng, Pidie Jaya in October 1972. Completed primary and secondary education in Trienggadeng and Banda Aceh. Bachelor's degree was pursued in Chemical Engineering Department of Syiah Kuala University with the major about water and wastewater treatment. Magister program was conducted  at the Environmental Engineering Department of Institute of Technology Sepuluh Nopember (1999-2002). Thesis research topic is bout application of membrane technology for drinking water treatment process. The research about membrane technology was learned in detail and intensively since pursues of doctoral program at Chemical Engineering Department, Kobe University – Japan (2005-2008).  Various polymer materials are selected and modified with organic or inorganic material in order to obtain a high performance of membrane. The fabricated membranes are then applied for processing of water and wastewater,  for protein purification,  and so on.  Up to October of 2017, several research about membrane preparation and its application have been explored in various technique, and the results of the investigation was publish in reputable journal.
