Abstract :

The  objective  of  the  research  are  to  monitor  of  floc  and  same  parameters  production  of Litopenaeus  vannamei cultured  in concrete pond. Two unit of concrete ponds  consist of one pond  real conccrete  pond  cemented  in  the  dike  and  pond  bottom,  it  size  3250  m2  (A  pond)  was  stocked  with  vanname post larvae day 10 at density 170 ind./m2 (561.200 ind.). The other one pond only cemented  in the  dike, whereas  the  pond  bottom  still    of  sandy  soil,  its  size    3915 m2  ( B  pond) was  stocked with vanname  post  larvae  day  10  at  the  density  148  ind./m2  (579.600  ind.).  These  ponds  were  monitored  started  from  pond  preparation  stages  untill  shrimp  harvested.    In A  pond  ,    after  two months  shrimp cultured, at every  two days  the pond waters was added 15 kg of molasses  in order  to enhance  the   CN ratio,  so  that  the  floc  can  growth  easily. B  pond was  control  pond without molasses  addition. Both  of these  ponds were  added with  varies  of  probiotic  shifted    daily. Monitored  on  srimp  feed  given  to  the shrimp showed that after post larvae stocked in pond, the feeed given to the post larvae at the dosage 3 kg crumble  feed/100.000  ind. post  larvae.   The quantity of shrimp  feed  increases  to 6 kg/100.000  ind post larvae at the day of culture 20 - 25. Then after that period the quantity of feed given to the shrimp follow the standard feeding program and depend on the feeding monitoring in trays (anco). Shrimp survival rate, production and  feed convertion were monitored after shrimp harvested. Water quality,  total bacteria and total Vibrio sp were monitored beweekly. TSS, VSS and  floc volume were monitored after floc develop in pond waters. Result of the research showed that floc develop in A pond at the day 75, while in B pond after  the day 90. Ammonium concentration  in pond waters was decreases coinsides with  the developing floc  in A and B pond. However, nitrite decreased only  in B pond and Vibrio sp population was stagnant. Shrimp harvested  in both ponds at  two  times,  first at  the day 110 and  secondly at  the day 140. Shrimp production attained   11.123,5 kg (34.226,15 kg/Ha), survival rate   88,55%, feed convertion 1  : 1,82 and shrimp size   41,7 – 52 ekor/kg  in pond A.    In B pond shrimp production  is15030 kg  (38.390,8 kg/Ha), survival     99,6%,  feed convertion 1  :   1,66 and shrimp size 36,5  – 46,5  ind./kg. Based on  this  research indicated  that  in  A  pond  more  fasted  floc  develop  compared  than  that  of  B  pond.  However,  shrimp production was  lower, feed convertion was higher  in A pond compared than that of B pond. Total yields in plots A (flock) of 11123.5 kg (34226.15 kg  / ha), with 88.55% survival rate, feed conversion 1: 1.82. The average size of 46 shrimp tails / kg. In plot B the production of 15 030 kg (38390.8 kg / ha), 99.6% survival rate, feed conversion of 1.66, the size of the shrimp tails 41.5 / kg. Based on these results suggest that  although  the  plot A  flock  is  formed  faster  than  in  plot  B,  but  lower  shrimp  production  and  feed conversion value  is higher  than  that obtained  in plot B. The analysis  focused on the cultivation of  farms with the highest production of plot B is converted in a total of 36 308 kg ha (an average of 34226.15 kg / ha - 38390.8 kg / ha) with a value of Rp. 805.465.160/season. Vaname shrimp farming can be done two times a year. Reveniu calculation cost ratio (R / C ratio) value of 2.02 indicates the feasibility of (2.02> 1) in  a  season  of  business, while  for  the  Benefit  cost  ratio  (B  /  C  ratio)  of  1.02  (1.02>  1)  is worthy  of sustained effort.
