<![CDATA[Cultivating land in agricultural activities requires optimal regulation of tractor requirements. The number of tractors that should be needed with the available land area is based on the availability of water in a subak with the aim of obtaining optimal tillage productivity, so a tractor with the availability of irrigation water is needed to irrigate the land to facilitate processing and streamline the land. The purpose of this study is to determine the number of tractors needed based on water availability by comparing the tractors available on subak. This study uses a quantitative analysis approach through a survey method by finding primary data, namely the measurement of discharge available for building and land measurements. The results showed that the tractors needed were based on the availability of water in the subaks of Tabanan Regency in theupstream, middle and downstream areas. For the nine subaks in the upstream area, the required rotary tractor with an average of 6 tractors can cultivate land reaching 87.3 ha or 1 tractor unit can work on an area of 14.6 ha with an average water consumption for 1 unit of tractor which is 27.16 lt/s. For the nine subaks in the central area of the tractor needed, with an average of 5 tractors, an area of 69 ha or 1 unit of tractor can work on an area of 13.8 ha with an average water consumption for 1 tractor unit, 26.84 lt/s. While the nine subaks in the downstream area of the tractor needed with an average of 10 tractors can cultivate land with an area of 114.5 ha or 1 unit of tractor can work on land with an area of 11.8 ha with an average water consumption for 1 tractor unit that is 12.1 lt/s.]]>
