Abstract

Tidal lowland is a potential land for aquaculture, however it should be manage intensively in order to give a good and sustainable contribution for society. Tidal fenomenon and rainfall will interacted with water quantity and quality which will used as fish media culture. Fish need optimal water to support its growth and survival. Based on measure and water analysis in two locations, at Mulyasari village, Tanjung Lago District, Banyuasin Regency, South Sumatera, tidal and rainfall gave effect to physical, chemical and biological of water quality and quantity. Related to the change of weather where in the second year (2016) the dry season was longer than rainy season since 2015,the rainfall was only about 200 mm- 310 mm/month. The lower of rainfall effected to the water level in canals and influent the brightness and turbidity, sea intrution that brought salinity about 5-15 ppt in the water.Acidity was also decline about 3.5-5 with ammonia- free reached 0.25 mg/L. Nitrate and nitrite were in common such a natural water condition, yet pyrite oxidized that caused the water and land tobe reddish yellow and looked like greasy in the surface. These condition would be harmfull for fish. The tidal and rainfall was also effect plankton abundance. The data shows that fitoplankton and zooplankton were higher in the canals than in the pond.

Abstract

Organic liquid fertilizer is the source of nutrients.  This fertilizer can be used to improve the water quality.  It is enviromentally friendly  and relatively cheap.  Application of the fertilizer has been done on aquaculture.  At the tidal lowland areas, application of this fertilizer is mostly as soil improvement agent.  It is limited to be used as water quality improvement agent.  Tidal lowland has an acid soil with a low fertility level characters. The objectives of the study are to know the effect of liquid organic fertilizer to the water quality (temperature, pH, dissolved oxigen, ammonia) and to the amount of plankton in the ponds. This research was done at the reclaimed tidal lowland in Banyuasin District of South Sumatera, Indonesia.  The organic liquid fertilizer was made by fermentation of  both animals manures and vegetable waste with the percentage of N : P2O5 : K2O were 0.120 : 0.023 : 0.750.  Water quality data was taken three times in every three days (plankton) from the ponds that was added by liquid fertilizer with dose of 4.35 L /pond (P1) and 8.7 L/pond (P2).  All the water quality data were analyzed qualitatively.  The results show that on treated  ponds pH dropped slightly since the beginning with pH 6.0 and remain 6.4 - 6.8 in the last day.   The value of  Ammonia ranges 0.06-0.15 mg.L-1 and Dissolve oxigen range 1.9-2.5 mg.L-1‑.    Phytoplankton and zooplankton amount increased and reached the peak on day 12 (12033 ind.L-1 and 364 ind.L-1 respectively), and finally turned down slowly.  Therefore, liquid fertilizer addition should be given to the ponds more than once during fish rearing period.  It is  in order to increase the amount of  plankton and to manage the water quality in the reclaimed tidal lowlands ponds
