Abstract

Cultivators can never run smoothly in their business, sometimes experiencing obstacles. One of the obstacles that is often encountered is the calculation of the number of fish seeds that are not correct/inappropriate due to the large number ordered up to hundreds or even thousands of seeds. In terms of counting fish seeds, fish cultivators have been serving fish buyers by doing the calculations manually, namely the fish are taken one by one from a container by hand, then transferred to the aquaculture pond. In calculating the seeds of this fish must be done accurately, efficiently, and quickly. Because in doing manual counting or moving fish one by one, if the fish take too long it can cause the fish seeds to become stressed because they cannot be separated from the age of the fish seeds which are relatively only a few weeks old. If the fish are stressed, of course it can cause the fish to die and can make fish cultivators lose a lot. Automatic Fish Counter tool system that can count koi fish seeds using the E18-DN80K sensor. This tool can be integrated via WiFi, namely using Blynk IOT. For the average occurrence of calculation errors when this system reads the number of fish seeds, which is 4%. It can be concluded that this tool can function properly to assist fish cultivators in calculating fish fingerlings when they have just bought fish seeds, or fish cultivators who want to sell their fish seeds by using an Android-based WiFi system application.

Abstract

A pump is a machine or device that raises liquid from a low surface to a higher surface or moves liquid from a low-pressure to a high-pressure area. A centrifugal pump is a machine or equipment used to provide energy to a fluid (liquid) based on the centrifugal force generated by a rotating impeller. So that the liquid can be moved or moved from one place to another. As it receives energy through the impeller, the fluid velocity will increase. This kinetic energy is then converted into compressive energy by the pump housing (casing) in the form of a spiral (volute) or a centrifugal pump or fixed blades (diffuser) surrounding the impeller so that the liquid exits the pump at a high speed. The maintenance method for the bilge pump auxiliary machine is carried out in 6 stages, namely, the first stage opening the filter box, the second stage removing the inner filter and filter box cover gasket, the third stage installing new anti-rust on the inside of the filter box cover, the fourth stage removing the box filter connecting faucet and the bilge pump pipeline, the fifth stage opens the connection of the pipe and the bilge pump, the sixth stage ensures that all components of the bilge pump are firmly installed and perform operational test
