Eel (Anguilla sp.) is a highly nutritious Indonesian marine commodity. However, information on the eel nutrient content in Indonesia is still limited. This study was aimed to determine chemical properties of Indonesian eels,Anguilla bicolor bicolor and A. marmorata. Proximate, amino acid, fatty acid, and vitamin A analysis were carried out on the fresh eel. The A. bicolor bicolor ontained 65.51% of moisture, 1.34% of ash, 16.78% of protein, 13.26% of fat, and 3.1% of carbohydrate. Meanwhile, results on A. marmorata showed it contained 57.17% of moisture, 1.09% of ash, 17.30% of protein, 21.35% of fat, and 3.12% of carbohydrate. Leucine and glutamic acid represented the highest essential and non-essential amino acid of both A. bicolor bicolor and A. marmorata, respectively. The highest saturated and monounsaturated fatty acid were palmitate and oleic acid for A. bicolor bicolor as well as A. marmorata. The content of vitamins in A. marmorata was higher than in A. bicolor bicolor.
Silkworm culture media (Tubifex sp.) are very important because it can be affected on growth and nutrient content of silkworm, such as fruit and vegetable waste. The waste disposal of fruit and vegetable in Rejang Lebong Regency have not been used properly, therefore this counseling aims of management of the waste of fruit and vegetable as and environmentally friendly silkworm culture media in Talang Rimbo Lama, Rejang Lebong Regency. The approach used includes meeting with the partnership, counseling, demonstrating, and evaluating. The counseling was interactive and communicative, and participants showed that considerable interest on materials presented. This counseling can improve knowledges and skills about silkworm cultivation and the use of the waste of fruit and vegetable as a silkworm culture media.
