Zainal Abidin Pagar Alam No.26, Labuhan Ratu, Kedaton, 35142, Bandar Lampung, Indonesia Abstract This study aims to determine the relationship between the level of output produced with the inputs used in conducting shrimp farming on Bumi Dipasena with samples of input and output of shrimp farming in Block 7 Foxtrot, Bumi Dipasena Jaya in 2017. The methodology in this study uses regression Cobb-Douglas production function. The results of this study are that the condition of shrimp farming on Bumi Dipasena block 7 Foxtrot for the 2017 period when viewed from the results is in a decreasing return to scale condition so that the addition of inputs for fries, medicinal feed and fuel is optimal and even unable to increase production output again.

Introduction Bumi Dipasena consists of 8 villages which have a total land area of 16,250 HA, divided into independent farming land (ex plasma) type of SHM: 6,800 ha (3,613 ha cultivation area, 3,187 ha supporting infrastructure area) and land ex CPP group (ex core) type HGU covering 9,450 Ha. The total number of ponds which is as many as 17,139 plots consists of productive ponds as many as 14,609 plots and less productive ponds (utilized by the people of these ponds. It is a failure of the CPP group reservoir system) as many as 3070 plots. There are inlet and outlet waterways along 1,300 KM. 1 At present some of the farmers in Bumi Dipasena manage their ponds, in collaboration with BUMDes with the Sub-Block Business Entity (BUSB) in each block which helps coordinate shrimp farming activities. One of the pioneers that has the most farmers applying this pattern of cooperation is Bumi Dipasena Jaya Village. But the problem is that in 4 periods for one year, the shrimp harvest is very diverse for each harvest period and for each farmer who does the cultivation. The harvest results are influenced by various input factors in the shrimp cultivation process, such as the number of fries distributed, feed, medicine, fuel for the pond producing oxygen, even weather or season conditions that affect the condition of pond water. The following is an example of the production of shrimp ponds on Bumi Dipasena Jaya in 2017: Figure 1 - Mapping of Shrimp Production Results with Boxplots
