Production of Fertilizer from Seawater with a Remote Control System

Seawater is abundant and full of nutrients known as ORMUS. Inorganic fertilizers have become scarce and expensive, so alternatives to feed plants are being studied. An automatic tank on a fishing boat was designed to extract salts from seawater, as follows: Sodium hydroxide is applied to seawater and agitated within a tank until its pH reaches 10.78. Salts begin to deposit, and the sodium mixed with the water stays at the surface. Water with sodium is removed after 3 h with a low-pressure pump. Clean water is added to the salty solution at the bottom of the tank to remove more sodium. Water at the top is sucked by the pump again, and the process is repeated once more. After the white salt (ORMUS) lying at the bottom of the tank is removed, the fertilization extraction process can start again. The automatic system regulates the agitator speed, pump filling and suction timing, and bottom valve opening.

Keeping lovebirds at home becomes one of hobbies that is fascinating to some people. Keeping them as pets means educate us to be regular people, particularly related to the process of food provision. Innovation on feeding bird is required such as automatic feeding which can be controlled from far areas. It will be very beneficial when the lovebird keepers are not at home. Therefore, this study develops at designing an automatic system for feeding birds completed with remote control. For this reason, the researcher used ESP8266 connected to NODEMCU as the hardware and BLYNK server as the control bridge of internet. The data would then be transmitted from smartphone to esp8266 system to control the feeding process. In the context of feeding process, the researcher used RTC-clock owned by BLYNK server to substitute RTC as the hardware. Automation system of food provision was carried out by synchronizing the data of hours from the users. The research data were used to design feeder bucket which could give food around 7.2 - 52.8 grams and feeder bucket B for accommodating food about 6.2 - 48.3 grams. The results of control and connection via BLYNK server demonstrated that 90% data were connected. In terms of data accuracy, this automatic feeder could be accurately 100% successful in a certain time.
