Comm. of Agricultural and Biosystems Engineering. All rights reserved.Currently, the Indonesian government calculates the operation and maintenance (O&M) budget by considering the size of the irrigation-area. The problem is that the O&M cost is not always proportional to the size of the area. In fact, infrastructure (such as irrigation channel and hydraulic structures) could be decisive in determining the amount of the required budget. This study will assess the difference in the O&M cost between the government’s policy and the new approach using Analytic Hierarchy Process (AHP) method. The new method has been formulated by the observation in West Java, and this study will attempt to apply it to the various irrigation-area or farms in Central Java. As for the result, the direct application of the formula will yield unsatisfying result hence improvisation is required. Thus, it can be concluded that the usage of AHP-based formula is not meant to be applied directly, but it requires technical considerations based on the characteristics of irrigation-area. By conducting further analysis, the previously-derived equation exhibits the abnormality i.e. the unrealistically high budget for the irrigation area with many facilities. It is also much more logical to have the linear proportionality between the budget and the number of infrastructure. By evaluating the previous work and the results from this study, the conclusion also converges to the linear relationship. Thus, while the exact equation in this study is not meant to be applied universally, the most important finding is how the O&M budget is linearly proportional to the number of infrastructures and is not only depended on the size of the farms.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]AHP,Area,Channel,Hydraulic structure,Irrigation infrastructure,O&M budget[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
