process brackish water into freshwater, starting by using simple technologies such as distillation,
filtration, and ion exchange. So, people who live in coastal areas can get decent clean water
(Abdillah, 2021).
If you look at the earth's surface which is mostly covered by water, it seems as if the water
sources in this world are very abundant. Now, 97.5% of the water on earth is seawater and
brackish water that cannot be drunk, and the remaining 2.5% is fresh water (Pidwirny, 2007). Of
the remaining 2.5% which is a source of water that can be used by humans, only 0.003%,
because most of the fresh water on earth is stored in the form of ice and glaciers or snow
deposits. Clean water reserves are distributed unequally on the earth's surface (Munge, 2010).
And from the results of the initial laboratory test, it was found that the condition of the river
water sampled at 07.00 Turbidity 36 NTU, Total Dissolved Solid (TDS) 1120 mg/L, Hardness
680 mg/L CaCO
3
, Cl 25.8 mg/L, Fe 1, 8 mg/L, and E.coli 1100 CFU/100mL.
Based on the description above, it can be seen that the river water sample exceeds the quality
standard. If river water is used as raw water for sanitation hygiene needs, it is necessary to have
technology to overcome this so that raw water can meet quality standards in accordance with the
Minister of Health Regulation Number 32 of 2017 Concerning Environmental Health Quality
Standards and Health Requirements for Sanitary Hygiene, Solus/Aqua Swimming Pools, and
Public Baths. With this limitation, residents are forced to consume water that is very cloudy and
far from healthy, so that water treatment can be carried out as a lesson for environmental
activists or lovers while increasing human resources in terms of applying appropriate technology.
Filtration studies can be in the form of a combination of coagulation, absorption, and ion
exchange as a treatment (Purwoto et al., 2017).
The application of the technology that researchers offer as an effort to overcome the clean water
crisis for the community uses Appropriate Technology (TTG) in the form of water treatment
with coagulation, filtration, and ion exchange treatments. Sucolite SP 210 is a clear liquid that
functions as a sedimentation and purifier. Then, filtration is the process of separating solids or
colloids with liquids using Ferrolite and Manganese Greensand. Furthermore, chemical synthetic
resins with certain organic functional groups that can function as ion exchangers use cation
resins and anion resins.
