The design of Litopenaeus Vannamei automatic feeder

The province of Bangka Belitung in Indonesia has a potential of ocean fishery production of about 1, 200, 000 tons per year. On the other side, there is another oppurtunity for the government to take advantage of the mainland usage for ocean fishery. Vannamei shrimp is one of the fishery product that can be farmed on mainland. Nowadays there are numbers of Vannamei shrimp's company in Bangka Belitung. Feeding process of Vannamei shrimp is one problem in this business. The food residual can cause about 60% of organic waste. To anticipate this problem, an automatic feeder has been developed, even though they are not optimized yet. The propose of this study was to design a new method of automatic feeder which can spread the pellets from 0 to required distance in meters and of a food transporter that can flow pellets properly. The machine has been designed to be operated using android-based system. This brings the ease of use to control and monitor the feeding process. The result shows that the automatic feeder can achieve 15 meter in maximum distance of food throwing. Spreading the food can be from 0 up to 15 meter based on the speed controlling of throwing (0 to 700 rpm). The auto-feeder can also be monitored using android system such as the volume of the food, and on/off the system manually.
