Evaluating Spatial Data Infrastructure for Subak Management in Tabanan Regency, Bali, Indonesia

Abstract

This investigation scrutinized the integration of geospatial intelligence in decision-making related to Subak management in Tabanan Regency, Bali. Focused on ascertaining comprehensive Subak data, evaluating local government readiness for Spatial Data Infrastructure (SDI) implementation, and constructing a web GIS-based Subak information system, this study was underpinned by a three-pronged methodological approach. Primary data was collected via interviewing Tabanan's Office of Agriculture personnel, supplemented by an in-depth secondary data analysis. Additionally, a web GIS, using QGIS and JavaScript, was developed. Findings revealed a significant deficit in the Office's preparedness for SDI implementation in Subak management due to the unavailability of critical SDI components. Consequently, a web GIS was constructed to facilitate Subak data dissemination. Usability testing suggested this system was 'easy' to use for 42.5% of respondents, while 52.5% found it 'very easy'. This research underscores the importance of Subak data provision and its potential role in decision-making processes for Subak preservation. The study was delimited to the evaluation of SDI in Tabanan Regency, and the development of a web-based GIS was executed using the t rf ll m th d
