a) The abundance of plankton
Parameter abundance of plankton in a body of water can reflect the level of fertility of a body of water. High abundance of plankton that can also show their dominance in the food chain. it can be used as indicators of a body of water.
Ways of working :
(1) Take the plankton samples that will be observed by using a plankton net
(2) Use a bucket volume of 10 liters to take a water sample, number of decision depends on the turbidity of the water, when the water was murky done 2-3 times a decision by the bucket full, if relatively clear waters do 5-10 times of sampling
(3) Pour water into a bucket into a plankton net that had been installed flakon (sample bottle) log volume flakon first.
(4) After filtering the plankton net to move the sample into a collection bottle, add 2-4 drops of 4% formalin
(5) Observation abundance of plankton using sr by shaking the sample bottle in advance
(6) Put the sample into the chamber until fully loaded sr, then cover with a cover
(7) In one observation sr containing 1 ml, identify at least 3 times the observations depends on the volume observed flakon
(8) Record the type and amount of each individual plankton found
b) Diversity plankton
Diversity can describe the biodiversity of plankton or kekeayaan of a body of water. but it can also be an indicator of pollution of the waters. observation of diversity together with observations of the abundance of plankton only formula that differs.

c) Index plankton dominance
The index value can indicate dominance dominance of plankton plankton species that exist in certain waters. dominance index value ranging from 0-1, the higher the index value indicates a domination of these waters are dominated by one or two types of plankton course, it can also illustrate the diversity that is narrow in teesebut waters. plankton dominance same observations with observations kalimpahan plankton, which differed only in the calculation of the data have been obtained.
