Abstract

Efforts to reduce protein in fish feed by maximizing the use of carbohydrates as an energy source must be supported by exogenous enzymes. One source of exogenous enzymes that can be used as a polysaccharide degrading agent easily obtained and wasted is rumen liquid in slaughterhouses (RPH). This study aims to determine the most effective carbohydrate level after being given rumen liquid as a source of exogenous enzymes in maximizing nutrient digestibility and feed efficiency in milkfish (Chanos chanos Forsskal). This study was designed using a Completely Randomized Design (CRD) which consisted of 4 treatments and three replications. Thus there were 12 experimental units. The treatments tested were feeds with various levels of carbohydrates (27.81%; 39.50%; 46.97%; and 56.75%) then given cow rumen liquid as a source of the enzyme at a dose of 80 mL/100 g of feed. Nutrient digestibility and feed efficiency data obtained were analyzed by analysis of variance (ANOVA) and continued with the W-Tuckey test. The results showed that feeding with various levels of carbohydrates in the feed that was first given cow rumen liquid waste had a significant effect (P<0.05) on fibre digestibility, carbohydrate digestibility, and feed efficiency of milkfish, but had no significant impact (P>0.05) on total digestibility, protein digestibility, and fat digestibility of milkfish. The most effective carbohydrate level in feed after being given cow rumen liquid which can optimize nutrient digestibility and feed efficiency of milkfish, is 46.97%.

Abstract

Siganus sp is one of the leading commodities that have high economic value. Until now, the market demand for Siganus sp continues to increase so that the prospect of its cultivation is very promising. The problem that arises specifically for fishermen in the coastal sub-district of Maros Regency is that there is no data and knowledge about suitable locations for the cultivation of Siganus sp. This study aims to determine the area that is suitable for cultivation of Siganus sp in the coastal district of Maros Regency. Data collection techniques were carried out by literature studies and direct field observations by taking coordinates and measuring oceanographic parameters (temperature, salinity, pH, brightness, dissolved oxygen, depth, current velocity). Water quality data were analyzed by weighting, overlaying and layout using GIS analysis. This research was conducted in the waters of the coastal sub-district of Maros Regency in January-August 2021. The results showed that the location of the suitability of Siganus sp aquaculture waters in the coastal sub-district of Maros Regency obtained suitable waters (S) for the development of Siganus sp cultivation covering an area of 630.36 ha and waters that are not suitable (N) for the development of cultivation Siganus sp covering an area of 681.2 ha.
