The aim of this job training is to improve knowledges, experiences, and skill about the making of sinking feed for vanamei shrimp begins from preparation, making, saving and knowing the obstacles or problems of making the artificial feed for vanamei shrimp. This training was held in Balai Besar Pengembangan Budidaya Air Payau which located in Bulu Village, Jepara District, Jepara Regency,Central Java. The job training started from July 17th 2010 until August 30th 2010.

Work method which used was descriptive method by collecting primary and secondary data.

Artificial feed made by BBPBAP Jepara is not commercial feed but made as one of improving science activity and improving of artificial feed production in Indonesia. Te improvement is held continuely to reach a good quality of artificial feed for Indonesian Shrimp farmer.Especially this job training study about the artifial feed production by using Skeletonema sp. powder as protein source. The process of this artificial feed production such as preparing and collecting raw material, arranging feed formulation, and making the artificial feed. Preparing and collecting raw material includes look over the quality of material consist of physic examination and chemical examination such as nutrition examination. For Arranging feed formulation, BBPBAP Jepara uses combination between person’s square method and computer method.

Artificial feed quality examination is done chemically and physically. Chemical examination is held by analyzing the level of nutrition contained in the feed.Physical examination includes color examination, smell examination, water stability, and sinking. The result of chemical examination shows 34,91 % value of protein , 7,62 % value of water, 18,70 % value of ash, 7,06 % value of fat, 3 % value of fiber, 28,71% value of BETN.
