EVALUASI KUALITAS SEDIMEN BEBERAPA TAMBAK UDANG DI KABUPATEN TULANG BAWANG PROVINSI LAMPUNG
ABSTRACT: Pond bottom management play an important role in the success of shrimp
culture. Study on the use of pond
bottom pond as an indicator of shrimp pond productivity is still limitted. Shrimp culture has been developing in tulang
Bawang Regency, Province of Lampung since early 1990. The waste produced by shrimp culture activity
is possible to reduce pond bottom soil quality due to high organic compund and
toxic material. The aim of this research was to evaluate the shrimp ponds
bottom condition in Tulang Bawang Regency, Province of Lampung. This research was an explorative one. Data collection was done towards 12 shrimp
pond units during water preparation period (pre-spreading) with the different
locations of each pond from the watergate. The collected data of pond soil
qualities were organic matter content, chlorophyll a, cation exchange capacity,
oxidation-reduction potential, pH, and soil texture. The research results
showed that soil qualities in shrimp ponds in Tulang Bawang Regency were still
in range for shrimp culture. In generally, shrimp ponds in the area have soil
textute of clay, sandy, and sandy clay.Chlorophyll a content, oxidation
reduction potential (ORP) and organic carbon matter content were 21,5 μg/g, 76
mv and 1,26% in average respectively.
Meanwhile cation exchange
capacity and soil pH were 11,2 me/100g and 6,8 in average.
