Abstract
Sutami Reservoir is located in Malang, East Java, Indonesia, is a multi-use reservoir to supply water for power plant energy source, agricultural irrigation, industry, communities and flood control. The functional of Sutami reservoir is decreasing over time caused by the reduced of reservoir capacity as a result of increasing in sedimentation rate every year. If this problem is not handled properly, it can be causing the failure of reservoir function. Various efforts have been done to overcome the causes of sedimentation in the upstream part of the reservoir intensively and sustainably. An innovative step is needed to increase the storage volume of Sutami reservoir. This step is to extend the lifespan of the reservoir. There are several alternative actions which can be taken, but this is still a polemic among experts and stakeholders. This is because many conflicts in criteria which are taken into consideration.
This study aims to determine the priority order of proposed alternative actions through the multi-criteria decision making process using the Analytical Hierarchy Process (AHP) method. AHP allows uniting the subjective qualitative assessments of individuals through importance-level pairwise comparisons into an assessment of group decision making.
The results of assessment from respondents of experts and stakeholders by using Social, Environmental, Technical and Economic criterias as a referrence, the selected first priority in order to increase the storage volume of Sutami reservoir is heightening of the dam body with the highest weight of 36.2%. Heightening of spillway/overflow is the second rank with a weight of 25.7%. This was followed by dredging of the sediment i.e 20.5%, and the last priority was the status quo with a weight of 17.7%.
