IPB University Researchers Create Shrimp Cultivation Technology, Able to Produce 130 Tons per Hectare

The IPB University research team has succeeded in creating a precise shrimp culture technology that can increase crop productivity. By combining the Recirculating Aquaculture System (RAS) and Biofloc cultivation systems, this technology is capable of producing up to 130 tons of shrimp in one hectare.

"What we are testing is shrimp farming by not replacing seawater much, with a recirculation system. Therefore, the rest of the feed and shrimp excrement must be converted into materials that do not produce toxins," said the Head of the Research Team, Prof. Bambang Widigdo when asked for information, 18/1.

He continued, the recirculation carried out should not reduce the flock much. This is because flocs or aggregates of feed residues, bacteria, protozoa and zooplankton can be used as food additives and to assimilate toxic gasses into non-toxic ones.

Prof. Bambang Widigdo explained that this shrimp cultivation technology is carried out in a greenhouse, where various parameters such as temperature and salinity can be conditioned. It is intended that the quality of the harvest can be maintained properly. In addition, shrimp farming with a greenhouse can also make water use more efficient.

“With maintained water quality, climate can be eliminated from fluctuations in temperature, optimal conditions can be achieved. So that growth can be faster. Because all parameters can be eliminated with full biosecurity, 300 to 500 shrimp can be stocked in one square meter,” he said.

He continued, cultivation with this technology has the potential to continuously produce six to nine kilograms per cubic. Even if the harvest is done partially, the potential can be 100-130 tons per hectare.

Partial harvesting is carried out in several stages. That is in 65 days, 75 days, 85 days, 105 days and 120 days. Where each harvest ranges from 15-20 percent of the population.

"If accumulated, per cubic meter can reach 10 to 13 kilograms. This means that the hectare can be 100 to 130 tons per hectare. Meanwhile, conventional cultivation will only reach 40-68 tons per hectare," he explained.

Dr. Wiyoto, Deputy Head of the Research Team, also hopes that this RAS and biofloc cultivation system can be an alternative technology for ponds that are no longer productive. Because with a small area, it can produce high productivity.

“With this concept, we can revive ponds that are not active, which are not productive. Because we have tested this technology and it is running well, so it can be developed widely and on a larger scale,” he explained.

In full, the research team consisted of Prof. Bambang Widigdo, Dr. Wiyoto, Dr. Zulaikasari, Dr. Sigit and involved 29 students, both from Vocational Schools and Bachelor programs. This very applicable innovation to be applied in society received funding from the Ministry of Education, Culture, Research and Technology within the framework of the Kedai Reka program.

The Chancellor of IPB University, Prof. Arif Satria said, "This greenhouse facility is one of the Teaching Factory (Tefa) owned by the Vocational School of IPB University. "The presence of Tefa is important for the compatibility between education and industry. In this way, education is able to be up-to-date, according to the times," he said.

"We want vocational graduates when they enter the industry, what they face is the same. Students who study in vocational schools, with this smart Tefa facility, when they graduate, are not surprised. Tefa aims to introduce industry to students, and present an industrial aura in the campus world," he explained. (*) (IAAS/SYA)
