“…This condition is identified by within the first 15 days, the volume of fresh water contained in the raw water is still large so make the salt content in the raw water is also small and causes the density (˚Be) to rise slowly, while on the 16th day the volume of fresh water has decreased a lot and there are remaining only salt compounds so that the density (˚Be) increases exponentially. Therefore, the increase in density depends on the volume of fresh water that is still contained in sea water [41,42]. The production time is 20 days from raw water entering the prototype until the water shrinks to a density of 27 Be.…”

In Indonesia, the famous method of the salt production process is evaporation using solar energy. The important aspect of this method is the evaporation rate. The evaporation rate is nearly related to the physical conditions of the surrounding environment. The aim of this study is to determine the evaporation rate of raw water in the production process using a prototype and determine the effect of physical parameters on the rate of evaporation of raw water in the production process in the salt house. The causal method with a quantity approach was used in this research. The results obtained are the total evaporation rate on the prototype at the Salt House is 1.68 litters/day and the results of Spearman rank correlation show that luminous intensity, air temperature, and wind speed have a significant impact on the evaporation rate because the significant value is <0.005 while the humidity level is not s significant effect.

Rechargeable sodium seawater batteries (SWBs) are gaining the world leadership of high voltage energy storage devices for marine environments. With natural seawater as the source of active material, SWBs can be supplied infinitely with Na cations. Because of their open-structured cathode, the cathode material’s specific surface area, porosity and wettability need to be optimized to achieve a high-performance cell. In this work, activated textile polyacrylonitrile (PAN) fibers were used to produce an activated carbon felt with a facile manufacturing process. The easy and low-cost production of these fibers makes them excellent candidates for energy storage applications involving oxygen evolution and reduction reactions. The electrochemical performance results of the fabricated activated PAN fibers and of commercial carbon felts were measured and compared, being characterized through galvanostic charge discharge cycles, electrochemical impedance spectroscopy and cyclic voltammetries. A performance improvement was observed with PAN activated carbon felt as half cell with a capacitance increase (about 9000%), and as full cell with a smaller voltage gap (about 10%) and increased gravimetric capacitance (about 260%) when compared to the commercial carbon felt. The successful implementation of PAN activated carbon felts in an aqueous environment opens new paths toward high performance seawater battery’s cathodes.
