The success of this aquaculture effort is determined through a handful of activity segments which are the key to the success of an effort to cultivate fish. One natural food that has high nutritional content is silk worms. Silk worms (Tubifex sp.) are a natural food that is widely used as fish food. The aim is to determine productivity, biomass and increase in worm population. The methods used in this activity are primary data collection, secondary data collection and documentation. The treatments given were treatments A and B, namely in the treatment of probiotics and 10% molasses with a media height of 5 cm and in treatment B probiotics and 20% molasses with a media height of 4 cm. The stages of implementing the activities included preparing containers, preparing culture media, spreading silk worms (Tubifex sp.), maintenance and harvesting of silk worms. The test parameters observed included absolute biomass, population increase and productivity. The results of the research showed that silk worm productivity, absolute biomass and silk worm population increase with the tray system with different doses in the highest media was in treatment A with a productivity value of 3.8 kg/m², total biomass 164 grams and population increase of 138 720 ind/m².
