Analysis on the Performance of Weir Based on Criteria Assessment of Building Functions and Structures Using AHP (Analytic Hierarchy Process) Method (Case Study of Samiran Weir in Pamekasan District)

This study aims to: (1) determine the criteria for evaluating the function and condition of the weir against aspects of the structure of the building, (2) obtaining weights of weir components that can be used as indicators of weir performance based on the condition and functioning of the building, (3) analyzing the weir performance at Samiran Weir in Pamekasan District is based on the condition and functioning of the building. This study took place in Samiran Dam located in Samiran Village, Proppo Subdistrict, Pamekasan District, East Java Province. Data collection technique was done by direct observation in the field which then the data was processed. From the results of data processing, the condition and functioning of Samiran Weir was analyzed. Data analysis used AHP (Analytic Hierarchy Process) method). The results of data analysis conducted from weir survey data resulted in weir performance based on component damage conditions in the form of a discharge weight of 18.89%, sediment weight of 1.25%, light weight of 0.19%, weight of retrieval building of 2.56%, weight of drainage building of 4.26%, weight of rinsing building is 1.88%, and the weight of the mud bag is 4.15%. As for the results of the analysis on the performance of the weir based on the component function, namely in the form of a discharge weight of 32.92%, sediment weight of 3%, light weight of 2.39%, weight of retrieval building by 14.29%, weight of drainage building by 21.14%, weight of rinsing building by 21.14%, and mud bag weights of 9.86%. The condition on the performance component of Samiran Weir experienced damage to components in the weir by 33.18% and the weir condition experienced MILD DAMAGE. The component performance function at Samiran Weir is 93.31% and the weir's function is in GOOD condition
