Abstract

The IMTA cultivation system is a cultivation system that combines several commodities with different trophic levels. In an effort to increase the productivity and sustainability of shrimp cultivation, the Pond-Water Integration (IMTA) system has emerged as a solution in the field of cultivation. Tiger shrimp cultivation using the IMTA system is a combination of two or three cultivation commodities, where nutritional/feed waste from higher level animals is consumed by lower level thropic animals. This research aims to determine the influence of the IMTA system on the growth of tiger prawns. The method used in this research is exploratory descriptive from various literature and research results that have been published, either from books, national journals or international journals. Based on a comparison of the results of previous research, it can be concluded that the IMTA system has a significant effect on the growth of tiger prawns, there are real differences in growth such as weight gain, relative growth rate, and survival rate of tiger prawns (P. monodon).

Abstract

Vaname shrimp (Litopenaeus vannamei) cultivation is growing rapidly in Indonesia and has various production scales, from traditional to super-intensive. This study examines the technical and economic differences of each production scale based on literature studies. Technically, the traditional scale still relies on natural environmental conditions with a stocking density of 5–9 shrimp/m2 and a productivity of 0.1–0.5 tons/ha/period. The traditional-plus scale is a development of the traditional scale with several improvements in technical aspects such as pond bottom soil processing, additional feeding, and simple water quality management with a stocking density of 10–49 shrimp/m2 and a productivity of 0.7–1.5 tons/ha/period. The semi-intensive scale begins to implement better aeration and water quality management, increasing the stocking density to 50–79 shrimp/m2 with a productivity of 4–8 tons/ha/period. At intensive and super-intensive scales, the use of technologies such as biofloc systems, Recirculating Aquaculture Systems (RAS), and Internet of Things (IoT) allows for higher stocking densities (80-150 shrimp/m2 and 250-400 shrimp/m2) with productivity reaching 15-20 tons/ha/period and 100-150 tons/ha/period. Economically, a more intensive production scale shows greater benefits. The traditional scale has an Internal Rate of Return (IRR) of 10-20% with a payback period of 3-5 years, while the semi-intensive and intensive scales have an IRR of 20-50% with a shorter payback period (1.5-3 years). The super-intensive scale offers the highest benefits with an IRR> 50%, a Net Present Value (NPV) of billions of rupiah, and a payback period of less than 1.5 years. However, intensive and super-intensive scales require large initial capital and more complex management systems, especially in terms of water quality and biosecurity. The results of this study indicate that increasing the scale of production can increase efficiency and profits, but also carries higher risks. Therefore, the selection of production scales must consider technical readiness, financial resources, and good risk management. The application of technologies such as biofloc, RAS, and IoT has the potential to increase the efficiency and sustainability of whiteleg shrimp cultivation. Support from the government and stakeholders is needed to increase the competitiveness of the aquaculture industry through policies that support innovation and sustainability.

Abstract

Tilapia filet is a fishery product that is widely favored because of its high protein content and ease of processing. However, this product has a relatively short shelf life, so natural preservation efforts are needed to extend its shelf life. This study aims to determine the optimal concentration of vinegar in the fermentation process of cassava peels to extend the shelf life of red tilapia fillets based on the number of bacteria during low-temperature storage. This research was carried out at the Fisheries Product Processing Laboratory, Biotechnology Laboratory, Aquaculture Laboratory, Faculty of Fisheries and Marine Sciences, Padjadjaran University in February 2024. This study was carried out by soaking red tilapia fillets using a fermented solution of cassava peel with different vinegar concentrations, consisting of 5 treatments, namely 0%, 0.5%, 1%, 1.5%, 2% and stored at low temperatures (50-100 C). The parameters observed were the number of bacterial colonies, and the degree of acidity (pH). The concentration of 0% observation was carried out on the 1st, 3rd, 6th, 7th, 8th, 9th day while the concentration of 0.5%, 1%, 1.5%, 2% was observed on the 1st, 4th, 7th, 8th, 9th, 10th, 11th, 12th and 13th days. Based on the results of the research that has been conducted, it can be concluded that a fermented solution of cassava peel with a vinegar concentration of 1% is the best to prolong red tilapia fillets based on the number of microbes and pH. The addition of 1% cassava peel fermentation solution can maintain the freshness of the fish until the 12th day with a total number of microbes of 3.3 x 107 with a pH value of 6.70
