Abstract

The enactment of PERMENTAN Number 10 of 2022 (Ministerial Regulation of Agriculture), which serves as a reference, indicates that pond farmers do not have the right to receive subsidized fertilizers. Additionally, the scarcity and rising prices of non-subsidized fertilizers in the market have led to a decrease in the productivity of fish and shrimp ponds, particularly those managed using conventional systems. This situation has also resulted in a decline in the income of the community as business actors. The objective of this community service activity is to provide guidance on cultivating Gracilaria sp. seaweed as one of the potential commodities that can be developed to maximize pond productivity. The socialization materials about seaweed Gracilaria sp. and its cultivation include preparation stages, seed spreading, monitoring, fertilization, harvesting, drying, storage in warehouses, and seaweed packaging. The results of this activity show the participants' enthusiasm to experiment with seaweed cultivation in one of the participants' ponds. Once it grows well, other farmers will begin to cultivate it. Farmers have understood about Gracilaria sp. seaweed and its cultivation, and they desire the realization and support of seaweed cultivation.

Abstract

The study was conducted to investigate the growth of juvenile whiteleg prawn (Penaeus vannamei) fed with different doses of the crown of thorns starfish (Acanthaster planci) meal in formulated diets. The study was designed using a completely randomized design consisting of four treatments and three replications.  The treatments were the dosages of A. planci meal in a formulated diet, namely A: 0% (control); B: 9%; C: 18%; and D: 27%. Juveniles of P. vannamei were reared in a 40 × 25 × 25 cm3 aquarium (15 Liter water volume) for 28 days. The results showed that the Individual Weight Gain (IWG) of juveniles ranged from 2.68 to 2.94 g, Specific Growth Rate (SGR) ranged from 2.82 to 2.93% day-1, feed conversion ratio ranged from 3.03-3.22, feed efficiency was 31.31-33.17%, and survival rate was 96.67-100%.  The analysis of variance revealed that the use of A. planci meal in a formulated diet did not have a significant effect (p>0.05) on growth performance (IWG and SGR), feed conversion ratio, feed efficiency and survival rate of juveniles of whiteleg prawn during 28 days of culture. The utilization of A. planci meal up to a dose of 27% can be used as a substitute for fishmeal as a source of feed protein for cultured whiteleg prawns.
