Pangasius fish is a freshwater fish that has a fairly high economic value in the market, both in the domestic market and foreign markets. This Pangasius fish is a type of fish native to Indonesian waters that have been successfully domesticated. The types of Pangasius fish in Indonesia are very diverse, including Pangasius djambal, Pangasius humeralis, Pangasius lithostoma, Pangasius nasutus, Pangasius polyuranodon, and Pangasius nieuwenhuisii. (DKPP, 2018).

To start fish farming requires quality water. Good quality water will produce good quality fish. Water quality is a significant part of developing better fish farming (Panggabean et al., 2016; Zamzami et al., 2019;). Determining the Pangasius fish farming system that is applied is also an important part so that the cultivation process takes place effectively and efficiently. The right cultivation system will have an impact on optimal fish growth. Growth can be defined as an increase in length or weight in a certain time range (Manunggal, et al., 2018).

One of the problems of aquaculture, especially Pangasius fish, is that the quality of the water environment has decreased. This is due to environmental pollution which is quite alarming. Therefore, it is necessary to have a cultivation system that is easy to implement to overcome these obstacles. Biopori technology can be applied to Pangasius fish farming. In general, biopori are holes in the soil that are formed due to various activities of organisms that occur in the soil such as worms, termites, ants, and plant roots. The formed biopori will be filled with air and become a place for the passage of water in the soil. The working principle of the biopori system for Pangasius fish cultivation is to make biopori infiltration holes. Biopori can be made as shown below:

The method used in the biopori system is a lime application to maintain the pH of Pangasius culture pond water. The goal of this technology is to improve the water quality of aquaculture ponds. The enlargement of Pangasius with this system has been studied by Manunggal et al which is applied to peatlands for 90 days or 3 months. The results of water quality measurements in Pangasius ponds with a biopori system can be seen in the following table:

According to the results of this study, for 90 days of rearing Pangasius fish on peatland with a biopori system, data on the pH of the water in a pond with a biopori system ranged from 5.8 to 6.3, while the Pangasius fish pond without a biopori water pH ranged from 5.1.-6.7. The pH level of the water in the biopori pond was more stable than the non-biopori pond, although it was not significantly different. In addition, the use of biopori technology to support the cultivation environment can also be applied to aquaculture waste handling technology with a waste siphon system (Manunggal, et al., 2018).
