THE SCALE OF PRIORITY FOR THE CONSTRUCTION OF IRRIGATION CHANNELS FOR STAKEHOLDERS PERCEPTIONS OF THE IRRIGATION SERVICE IN SIDOARJO REGENCY

Sidoarjo Regency is one of the megapolitan Gerbang Kertosusilo. The planted area during the rainy season and dry season reaches 30,000 ha. The area of paddy fields continues to decline, namely 26,334 ha (2002), 22,460 ha (2010), and an estimated 13,544 ha (2009– 2029). Sidoarjo Regency Irrigation Service as executor of irrigation management is of course inseparable from construction project activities. In the implementation of the construction of new irrigation networks as well as in rehabilitation and maintenance, it is necessary to implement project management. Before the project is implemented, it must first be submitted through proposals from the village level. In following up the proposal the writer used the Analytic Hierarchy Process (AHP) analysis method. With four aspects that affect the determination of the proposal: The results of the analysis obtained the weight of each criterion as follows: Service Area (ha) 0.3179, Cost 0.3159, Benefits 0.3217, and Network Conditions 0.0445. The results of the above analysis obtained priority ranking from the first to the last sequence as follows: Plengsengan Gedangrowo Channel, Normalization of Reform Channels, Installation of floodgates, Plengsengan ChannelsDs. Suwaluh, Rehabilitation of Ketawang Canal Kec. Sukodono, Rehabilitation of Candi Subdistrict Channel, Plengsengan Channel Ds. Suwaluh, Plengsengan Channels Purboyo II Ds.

Introduction
Sidoarjo Regency is one of the megapolitan Gerbang Kertosusilo. LP2B is implicitly stipulated by Perda No. 6/2009concerning RTRW 2009-2029(Sidoarjo Regency Government, 2009). The RTRW Perda states that LP2B is set at 13,000 ha with a potential land area of 22,000 ha, consisting of 5,000 ha of sugarcane and 17,000 ha of rice. The planted area during the rainy season and dry season reaches 30,000 ha. The area of paddy fields continues to decline, namely 26,334 ha (2002), 22,460 ha (2010), and an estimated 13,544 ha .
The increasingly limited and competitive availability of water resources will not only have a negative effect on socio-economic life and among users in a sector. The dominant level of water demand outside the agricultural sector is to meet household and industrial consumption, which tends to increase in line with economic progress.
According to Rahman (1999), irrigation management is an effort to distribute water fairly and evenly, but the mechanism is often faced with several fundamental problems, namely: 1) the number of water group areas increases uncontrollably, 2) the relative location of the plot of rice fields from the channel is not taken into account. in water distribution and technology advice which is in the downstream (tail end), 3) illegal water tapping on the way continues without any variation between upstream and downstream parts. If we look at this problem, it is inseparable from institutional elements and policy instruments that have not functioned effectively in an effort to make people aware of the importance of water management.
Irrigation is very important in supporting food security, especially national rice production. Therefore, the central government, through the Office of Public Works for Irrigation, Sidoarjo Regency, annually receives APBD funds to be used in the rehabilitation and maintenance of the existing irrigation network system in Sidoarjo Regency. From year to year, the given budget continues to increase in order to support the food self-sufficiency program that has been launched by the central government. On the other hand, these offices are also required to absorb the budget according to the achievement targets set in the DPA each year. http://pupengairan.sidoarjokab.go.id/tugas-pokok-dan-fungsi/ In the implementation of the construction of new irrigation networks as well as rehabilitation and maintenance of irrigation network systems, project management is very necessary to be implemented. Project initiation starts with a need and goes up to the implementation stage. Before the project is implemented, a project proposal is first carried out. The proposal of a project is the result of selection from the number of needs that must be realized and in selecting a project proposal there are many factors that must be considered so that in its implementation it can minimize all risks that can hinder work in the field.
Criteria for the Regional Medium Term Development Plan (RPJMD) of Sidoarjo Regency in 2010-2015, subscribers to the irrigation network currently number 318 location points, while several programs have been launched, namely: maintenance, normalization, construction of dam gates and construction of plengsengan.
In following up on these proposals, so far there has not been an accurate method used, so that there are often inaccuracies. Therefore, in this study using the analytic hierarchy process (AHP) method in determining the appropriate priority scale for handling irrigation networks and careful calculations, so that goals can be achieved and do not reduce the quality of work. Based on the background above, it can be formulated as follows: 1.How big is the weight of each of the criteria for the Determination of the Priority Scale of the Irrigation Canal Construction Project in Sidoarjo Regency Irrigation Service. 2.How big is the weight of each activity against the criteria for determining the priority scale of the Irrigation Service Irrigation Service Development Project in Sidoarjo Regency? What is the priority ranking for each activity to determine the Priority Scale for the Irrigation Canal Construction Project for the Irrigation Service of Sidoarjo Regency.

Material and Methods
The methodology used in this research includes literature review and study, data collection, preparation and application of the Analytical Hierarchy Process decision model. The sample in this study was taken as many as 20 respondents consisting of expertists as follows: 2. Creating a hierarchical structure starting with a general objective, followed by subobjectives, criteria and possible alternatives at the lowest level of criteria. 3. Creating a pairwise comparison matrix that describes the relative contribution or influence of each element to each goal or criteria that are a level above it. Comparisons are made based on the judgment of the decision maker by assessing the importance of an element compared to other elements. 4. Perform pairwise comparisons, starting from the top level of the hierarchy aimed at selecting criteria, for example X, then the elements to be compared are taken, for example X1, X2, and X3. Thus, the arrangement of the elements being compared will look like in Table 2.
The determination of the relative importance value between elements uses a scale of 1 to 9 as in Table 3. If an element is compared to itself it is given a value of 1. If element i is compared to element j gets a certain value, then element j is compared to element i is the opposite. 5. Calculating the eigenvalues and testing the consistency, if not consistent data collection is repeated. 6. Repeat steps 3,4, and 5 for all levels of the hierarchy. 7. Calculate the eigenvectors of each pairwise comparison matrix. The eigenvector value is the weight of each element. This step is to synthesize judgment in determining the priority of elements at the lowest hierarchical level until the achievement of goals. 8. Checking the consistency of the hierarchy, if the score is less than 10 percent then the judgment is accepted. 9. Check hierarchy consistency. If the value is more than 10 percent, the judgment data assessment must be corrected.  Criterion / alternative A is as important as criterion / alternative B 3 Criterion / alternative A is slightly more important than criterion / alternative 5 A clear criterion / alternative A is more important than criterion / alternative 7 Criterion / alternative A is clearly more important than criterion / alternative 9 Criterion / alternative A is absolutely more important than criterion / 2,4, 6,8 When in doubt between two adjacent values Source: Processed Results

Criteria Weight Analysis Between Criteria
In the AHP analysis process, the first step is to tabulate the results of respondents' answers using an Excel Template with multiple Inputs Klaus D. Goepel. (Attachment 1) Determination of variable priority values is done by making a paired comparison table of influence, namely, as follows: Furthermore, to determine the weight of each criterion, a comparison of the criteria is used. The next step is to divide the value of each matrix element in appendix 1 by the number of each column. The quotient can be seen in: The calculation results in the Consistency Ratio (CR) value of 0.0088 ≤ 0.1, then it is accepted. if the CR value is more than 0.1 then the CR is rejected. IR = 0.9, taken from the rules of the random index table that have been determined according to the size of the existing element matrix. IR = 1.24, taken from the rules of the random index table that have been determined according to the size of the existing element matrix.

Activity Weight Calculation
In the AHP analysis process, the first step is to tabulate the results of respondents' answers using an Excel Template with multiple Inputs Klaus D. Goepel. (Attachment 1) Determination of variable priority values is done by making a paired comparison table of influence, namely, as follows: Furthermore, to determine the weight of each activity, the pairing comparison between activities is used.  In the fourth iteration, the calculations are generated as in Table 3.5. where the pairwise multiplication ratio is close to zero so that it can be said that the calculation is sufficient to take the result. From the calculation results, the global weighting value is obtained where the criteria have an influence on the priority determination of the irrigation project development activities of the Sidoarjo Regency Waterworks Office with the highest weight level of Plengsengan Gedangrowo Channel, the second is Reformation Channel Normalization.
