Basically, the catfish farmers in the country still use the traditional way in the cultivation of this mustachioed fish. So that the yield is not maximal. But along with the birth of new innovations are now modern catfish cultivation gives better yields to multiply. This makes some catfish farmers change the catfish cultivation of the old system to a modern system using a recirculation system.
Catfish included in the Catfish family that has many types and varieties. Like the local catfish, sangkuriang, phyton catfish, regular catfish, dumbo catfish etc. How to cultivate catfish in different communities. But the most popular is the catfish breeding in modern tarpaulin ponds. Because it is relatively easy to do with business capital is quite a bit and can be done on a narrow and limited land even with multiply crops. To harvesting the fishcaat use the power of the machine that uses the PLN
Inspired by catfish farmers who at the time of harvesting the fish still use the power of the machine that uses the PLN so that the operation is still expensive, besides that there are still many breeders who do penen traditionally so that the results are not maximal make Ayyin Layyinum from SMK Negeri 54 Jakarta Indonesia make the harvest catfish using solar power. With this work Ayyin Layyinum became one of the winners in the National Young Inventor Award held by the Indonesian Institute of Sciences in Jakarta in 2015.
The principle of working this tool is made in the net placed on the bottom of the pond or pond, the net is connected with a string that is connected to the tool. This tool is equipped with solar panels that serve to generate electric current coming from sunlight or light bulbs, in addition there Changer Controler that serves to control the incoming voltage from the solar panel to the battery so as not to experience over-changer
After that there are two switches, namely switches on and switch of which serves as a connector and an electric current breaker, the battery as an electric current storage and DC motor that serves as a puller and plunger rope connected to the net.
With this discovery is expected to be applied to the catfish farmers for the benefits of their catfish pond is increasing, because by using this tool it can save both the power and costs due to electricity consumption from the state electricity company or PLN.
