Background and Objective: Vaname shrimp (Litopenaeus vannamei) is one of the main economic commodities in aquaculture in the world. Biofloc is a cultivation technology that effectively improves the growth and health status of vaname shrimp. This research aimed to analyze the use of bagasse as a carbon source in the biofloc system for white shrimp cultivation. Materials and Methods: The shrimp used were 18 g/individual shrimp obtained from the Bone Marine and Fisheries Polytechnic Pond. Sugarcane bagasse processed from sugar factory waste was dried in an oven at 60°C and ground using a flouring machine. The research treatments included biofloc application where sugarcane bagasse played a role as a carbon source (L), biofloc application where wheat flour's role was as a carbon source (T) and control or no biofloc application (K). Results: This research showed that sugarcane bagasse could be used as a carbon source for white shrimp biofloc cultivation where the growth value tended to be the same as wheat flour. Total hemolytic count (THC) and shrimp survival in sugarcane bagasse biofloc were as good as wheat flour biofloc. Sugarcane bagasse biofloc had the same ability as wheat flour biofloc in reducing ammonia levels in the rearing media. Sugarcane bagasse biofloc had the same ability as wheat flour biofloc in reducing ammonia levels in the rearing media. The application of bagasse had no effect on temperature, pH, dissolved oxygen and salinity of the rearing media because this treatment was in the optimal range for the growth of vaname shrimp. Conclusion: Sugarcane bagasse has the potential to be a carbon source in biofloc systems because it could improve growth, health status, survival and water quality.

Intensification is part of modern shrimp farming technology, feed, and high stocking density. High density could save time and production costs. This research aimed to determine the optimal tolerance of shrimp larvae with high stocking density per bag unit without oxygen liquid in terms of environmental physiology (ecophysiology) and economic feasibility aspects (bioeconomics). The shrimp larvae used were post-larvae 10 with a weight of 0.0026 ± 0.0021 g, which were previously fasted. The method used was a simulation of a three-hour trip with treatments: 200 larvae/packing (control), 400 larvae/packing, and 600 larvae/packing. The treatment for each packing was 450 ml of water and oxygen gas and added ice cubes in each styrofoam during delivery at night. The results showed that the stocking density of 600 larvae/packing had the best value. In terms of ecophysiology, the survival rate was highest when arriving at the location, with 98.20% of total larvae. The lowest oxygen consumption in the metabolic process was 0.76 ± 0.10 mg/L. Reviewing a bioeconomic, the potential profit per packing reaches IDR 995,528. It can be concluded that the use of oxygen gas and the addition of ice cubes in transportation increased the survival of shrimp larvae.

BACKGROUND AND OBJECTIVE
Vannamei shrimp Litopenaeus vannamei is an economically valuable aquaculture commodity but still faces problems due to disease and growth performance. Buton forest onion extract Eleutherine bulbosa (Mill.) Urbhas been shown can protect the shrimp from disease. This study aimed to evaluate the potential of the Buton forest onion extract on the growth of vannamei shrimp in tarpaulin pond.
MATERIALS AND METHODS
The experiments were conducted for 90 days by adding Buton forest onion extract in feed at a dosage of 40 g kg-1. The Buton forest onion bulbs was extracted by maceration method using 96% ethanol. The test feed was made through the re-pelleting method. Treatment include supplementation of Buton forest onion extract diet supplemented with Buton forest onion extract diet at twice a week (treatment A) and control was without Buton forest onion extract(treatment K). Parameter measurement include final weight, average daily growth (ADG), feed conversion ratio (FCR), survival rate and water quality (temperature, salinity, turbidity and pH).
RESULTS
This study was demonstrated the addition of Buton forest onion extract on feed with a frequency twice a week in significantly improve the growth performance of vannamei shrimp by improving the final weight and average daily growth at 65 and 90 days of maintenance. Water quality during the study was still within the optimum range for L. vannamei shrimp growth.
CONCLUSION
This study showed that supplementation of Buton forest onion extract was able to improve the growth performance of shrimp in tarpaulin ponds.
