PERBEDAAN KEMAMPUAN CANGKANG KERANG, CANGKANG KEPITING DENGAN CANGKANG UDANG SEBAGAI KOAGULAN ALAMI DALAM PENJERNIHAN AIR SUMUR DI DESA TANJUNG IBUS KECAMATAN SECANGGANG KABUPATEN LANGKAT
Abstract: Water is a basic
need for human life on this earth. Human life needs water to support their
daily life. The water need varies depending on climatic conditions, living
standards, and culture of the people. People in the village of Tanjung Ibus,

water supply. The condition of wells water and bore dug wells in the village
physically looks turbid and brackish and some people do not use a water filter

Secanggang Langkat district. Analysis of the data was using one-way ANOVA
statistical test with α = 0.05%
Based on statistical test, the highest average reduction of water
turbidity was shell calsium carbonate as 95,28 and the lowest was 91,58% in
control. As well as the pH decreased by 28,57% from 7.0 to 5.0 on the addition
of coagulant. Based on One-Way ANOVA test the turbidity in well water obtained
that there isn’t a significant difference among the ability of calcium
carbonate shells, shell crab chitosan and shell shrimp chitosan as natural coagulants in water purification , p
value = 0.05. For that it is needed the role of the society and the government
