Carrot (Daucus carota L.) Farming Agribusiness of Efficiency Analysis and Supply Behavior at Bumiaji, Batu-Indonesia

Batu city as an administrative region islocated in East Java. The level of productivity of carrots in Batu reached 17.94 tons/ha, harvested area reached 509 hectares and production reached 9,132 tons. The aims of the research are: (1) To analyze the allocation of carrot production factors in Bumiaji district of Batu city, (2) To analyze the efficiency level of carrot production factors in Bumiaji district of Batu city, (3)To analyze the return to scale of carrot production factors in Bumiaji district of Batu city; and (4) To analyze the factors that influence supply behaviour of carrots in Bumiaji district of Batu city. Production factors are a significant effect of seed, labor, and pesticides. Results NPMx/Px or the value of marginal productivity of each input (NPMxi) that indicatesefficiency level at an input price (Px) for seed is 4.19 > 1, so it is not efficient. NPMx/Px for the use of pesticides is equal to 0.84 1, so it is not efficient. Production function model shows that the elasticity is 0.905 on a constant return to scale. Three variables that significantly affect the supply behavior of carrots are the harvest area in time t, the real producer price of carrot in time t, and the real retailer price of carrot in time t. Suggestions that can be given are to address the optimal use of seeds that have not been added in the area of 1 hectare of 108.61 kg and 739.11 for labor HOK. Variables of the real fertilizer price in time t and the real pesticide price in time t are not significant to the level of supply behaviour. It is necessary to be reduced in implementation in their farm
