PENYEDIAAN ENERGI LISTRIK BERBASIS PERBEDAAN SALINITAS DENGAN MENGGUNAKAN TEKNOLOGI REVERSE ELECTRODIALYSIS
ABSTRACT: Since the formation
of the Kyoto's Protocol and is based on reports of the Intergovernmental Panel
on Climate Change (IPCC) about the capture and storage of carbon dioxide gas in
order to reduce the rate of climate change, there is a continual effort that oriented
to the handling of CO2 emissions into the atmosphere, Although Indonesia has
never been obligated to reduce its emissions, but this policy will have a big
impact on Indonesia, especially in the energy sector. Until now, oil is still
the main source of energy in fulfilling energy needs within the country. The
role of a very large petroleum will continue, while the dwindling petroleum
reserves.Recognizing the dependence on fossil fuels, there should be an effort
to press the growth of the use of fuel oil . Nowadays, it has developed an
alternative energy known as the Salinity Gradient Energy (SGE). Sanility
Gradient Energy has great potential for use as an alternative energy especially
in Indonesia, which is the state waters. This research is aimed for study the
effect of the concentration of concentrated NaCl solution, dilute NaCl solution
flow rate, feed of seawater synthesis and real sea water in generated of power
density. This research started inmaking a concentrated NaCl solution with
various concentrations of as much as 2 l and a dilute NaCl solution with a
concentration of 1 g/l as much as 2 l. Continued with the second turning on the
pump diaphragm for both types of feed solution flow into the channels contained
in a series of tools. After a few moments appliance operates, the change of
output voltage (V) and electric current (A) can be measured using a
multitester, this measurement conducted every 20 seconds interval. and then
repeat the same steps for each of the variables that have been defined.From
this research was found that increase in feed flow rate, then the resulting
power density is greater, because of the increased flow rate causes the rate of
movement of ions to the electrode increases. on increasing of the concentrated
NaCl solution, the resulting power density is greater, because of the increased
concentration difference causes an increase in the chemical potential. And for
sample nearly the same concentration (30 g/l), the resulting power density of
sea water is greater than the synthesis of real sea water, because the value of
electrolytes activation synthesis of sea water is greater than the real sea
water. It can be concluded that the increase in flow rate and concentration,
can increase the generated of power density.
