Abstract

The waste water of copper board etching process in Printed Circuit Board (PCB) production is kind of heavy metal waste water, that is copper, which has not been treated yet. In order to prevent the environment contamination process the waste water should be treated before thrown to environment. The kind of waste water treatment that will be applied to the waste water with heavy metal content, specially copper metal (Cu) is electrolysis method. The experiment was done in laboratory scale. The batch electrolysis reactor was used in this experiment, with the copper as katoda and stainless steel as anoda. Electrolysis process was conducted with waste concentration variation that was equal to 124,16; 110,96 ; and 35,84 ppm. The result of the experiment shows that, the electrolysis methode could reduce copper concentration in the waste water of etching process. The biggest efficiency degradation for the variation of waste concentration was happened at waste concentration 35,84 ppm, that was equal to 100%, with end result equal to 0 ppm. Waste concentration equal to 124,16 of ppm its result 96,24 ppm, and for concentration 110,96 ppm was got by result 0,35 ppm.

Abstract

New and Renewable energy is not only an alternative energy that can meet increasing energy needs, but also green energy that does not cause harmful effects on humans and the environment such as energy derived from fossils. The application of solar cells as a source of electrical energy to modern agricultural systems, especially the aquaponics system is one of the efforts to develop new and renewable energy that is environmentally friendly. This research is a technological innovation that can cover the weaknesses of aquaponic systems in general by using solar panels to convert solar energy into electrical energy and equipped with water circulation automation technology so that the water needs are always guaranteed. The design of automatic water circulation regulator hydroponic planting method uses a timer as an automatic, solar panels as energy converters, solar charge controller as a regulator of electric current balance. The implementation of this research consists of several stages, namely: the initial data collection stage, the system development stage, and the research data collection stage. The results showed that the water pump in the aquaponic fish pond on the first, second and third days showed that the water pump was 12 V and the average flow of the fish pond water pump was 1.15 A. The data also showed that The highest measurement carried out for 3 days resulted in an average voltage of 12.68 V and a current of around 1.75 A, and the lowest measurement produced an average voltage of 12.42 V and a current of around 1.63 A. Based on the data in the study this, solar panels with a large 50 wp can meet the load requirements (water pump) to operate so that they can help circulate water in aquaponic installations.
