Abstract

Aplication of pumpkin skin flour Curcubitae sp. to improve of the water quality performance and support shrimp Litopenaeus vannamei growth, it necessary to do an analysis. Pumpkin skin Curcubitae sp. as a source of stimulants needed by bacteria to survive in the nitrification denitrification processes in aquaculture as an alternative to environmental friendly with bioremediation system evaluation. Its mesophilic nature and a organic ions source for bacterial growth. Pumpkin skin can support the growth and activity of nitrifying denitrifying bacteria in the environment. This study aims to determine the best of dose of pumpkin skin as a biostimulator of nitrifying denitrifying bacteria growth. The treatments used were pumpkin doses of 0%, 2%, 4%, 6% for 20 L culture water. Giving pumpkin flour can improve the performance of abundance and activity of nitrification denitrification bacteria. The activity of nitrifying bacteria can be seen from the presence of ammonia value which is relatively more stable compared to other treatments. The best oxidation of ammonia in 6%, and reduction nitrite in the 4% treatments. The treatment of 4% was effective in maintenance for 30 days which could maintain the stability of water quality and increase the growth of vaname shrimp.

Abstract

Pond bottom sediment conditions influence shrimp culture. As benthic organisms, shrimp are mainly on the surface of the pond bottom, so cultivation preparations related to improving sediment quality are essential. Pond bottom practice, such as drying, liming, and fertilizing, is common. However, in bottom pond conditions where total drying cannot be carried out, other treatments are needed, such as the addition of hydrogen peroxide. The purpose of this study was to determine the effect of adding hydrogen peroxide in pond sediments on the performance of shrimp growth and water quality. The study was conducted with five doses of hydrogen peroxide (0.25 mL, 0.5 mL, 1 mL, 2 mL) mixed with 350 g of pond soil sediment. Ten shrimps with an average weight of 0,27±0,03 g were put into the rearing container, which had been given pond bottom sediment according to the treatment. The results showed that the 2 mL hydrogen peroxide treatment gave the best results on the growth rate and average weight of Pacific whiteleg shrimp at the end of rearing. Water quality such as pH value, dissolved oxygen, and temperature were not significantly different between treatments. Hydrogen peroxide treatment can improve shrimp growth performance without affecting water quality during rearing.
