Abstract

Vaname shrimp (Litopenaeus Vannamei) is one of Indonesia's fishery commodities with high economic value. Vaname shrimp production in Indonesia continues to increase. However, obstacles sometimes arise in cultivation activities, such as the emergence of shrimp diseases and poor water quality. High stocking density and shrimp feeding can cause a decline in water quality. In addition, pond water quality is influenced by pond location and the surrounding environment, such as agriculture, settlements, mangroves, and the sea. This causes ponds to have different water qualities. One of the diseases that often attacks shrimp farming is caused by the bacterium Vibrio sp. The abundance of Vibrio sp. bacteria is closely related to pond water quality and the environmental conditions around the pond. The methods used were TPC testing and multiple linear regression testing. Based on the results of the study, the abundance of Vibrio sp. bacteria in pond A was the highest at 8.3 x 102, and pond C had the lowest at 3.1 x 102. Water quality testing in three different ponds showed safe limits for cultivation, except for nitrite testing. Based on the simple linear regression test, the water quality parameters that significantly affect the abundance of Vibrio sp. bacteria are pH, temperature, and nitrite.

Abstract

Biofloc technology is a super-intensive fish cultivation method, which benefits heterotrophic bacteria to harvest organic chemical compounds and amines from fish metabolic residues to be converted into bacterial proteins. The use of probiotics is very important to be carried out in cultivation activities, Probiotics are living microorganisms that have a beneficial effect on humans by balancing the microflora in their intestines. The bacteria in probiotics have a mechanism in forming several enzymes for feed digestion. This study aims to determine the effect of administering Pro Top probiotics with different doses on the absolute weight growth of tilapia (Oreochromis niloticus). Probiotics are mixed with feed with a biofloc cultivation system. The method used in this study is an experimental method with a Completely Randomized Design (CRD) with 4 treatments and 6 replications, namely by adding different doses to the treatment. Treatment A (0.5 grams / kg), B (1 gram / kg), C (2 grams / kg) and D (5 grams / kg). The parameters observed are absolute weight growth. Supporting parameters for air quality are temperature, pH, and DO. Data were analyzed using the ANOVA test. Based on the results of the study, it shows that administering different doses of Pro Top probiotics has a significant effect on the absolute weight growth of tilapia (Oreochromis niloticus). Treatment A (0.5 grams/kg) gave the lowest absolute weight growth of 31.05 grams and treatment D (5 grams/kg) gave the highest absolute weight growth of 40.30 grams. Air quality parameters including air temperature ranged from 25.3 – 26.1°C, acidity level around 7.5 – 8.0. And dissolved oxygen ranged from 4.7 – 5.3 ppm. The results of the analysis of variance (ANOVA) of the three air quality parameters showed no difference between the treatments of tilapia (Oreochromis niloticus).
