Abstract

Lobsters are carnivorous (meat-eating) animals, one of the main types of feed used in lobster cultivation is trash fish. Trash fish has a protein content of 84.67% on dry weight and 18.78 on wet weight. The purpose of this study was to determine the growth of sand lobsters (Panulirus homarus) by providing moist feed and adding different doses of probiotics. This study used the RAL method (completely randomized design) with 6 treatments and 3 replications. The study was conducted for 60 days using sand lobsters measuring 3 cm in length and weighing 2 grams/head, then reared in KJA. The results showed that the use of wet feed with the addition of probiotics in this study had a significant effect on the growth of sand lobsters. The best probiotic dose obtained was 3% in the P2 treatment (wet feed + 3% probiotics). The absolute weight and length are 91.23 grams and 4.19 cm; Specific gravity and length 1.74 grams and 1.46 cm; SR of 81.33%; FCR of 7.60 ; Feed efficiency 91.30%; and protein retention of 28.86%. The growth of sand lobsters continued to decline along with the high doses of probiotics given. Giving probiotics with different doses is thought to affect the value of protein in feed. Laboratory test results showed that the protein value continued to decrease along with the high doses of probiotics given. The author suggests using different types of probiotics to determine the type and effective dosage for the growth of sand lobsters.

Abstract

The high price of protein feed for livestock makes maggots potential as an alternative protein feed. The first stage in this research was maggot maintenance and maggot harvesting on the 15th day of maintenance. Next, measurements of the physical and chemical quality of fresh maggot were carried out. Parameters for measuring the physical quality of fresh maggot consist of harvest weight, individual weight, individual length and color. The parameters for measuring the chemical quality of fresh maggot consist of water content, ash, crude fat, crude fiber and crude protein. Data analysis was carried out using the Independent Sample T-test. The results showed that the maggot that was cultivated with the special media used had an average harvest weight of 1.24 kg, while the maggot that was cultivated without the special media used had an average harvest weight of 0.72 kg. The maggot that was cultivated with the special treatment of the media used contained 31.5% protein, while the maggot that was cultivated without the special treatment of the media used contained 32.9% protein. The conclusion of this study is that maggot that is cultivated with the special treatment of the media used produces maggot with superior physical quality compared to maggot that is cultivated without the special treatment of the media used.
