This study dealt with three specific objectives, first of which aimed to distinguish the significant difference in the amount of oil absorbed being treated by human hair and chicken feathers in different concentrations of oil to water. After the using variance analysis with significant interaction, the researchers found that there was a significant difference in the amount of oil absorbed by applying groups of samples containing chicken feathers and human hair under the different absorption time. The second objective was to determine whether there is a significant difference in the amount of oil absorbed by the chicken feathers and hair in terms of absorption time. It was found out that there is a significant difference in the amount of oil absorbed by the two groups of samples under the same oil-to-water concentration was proven. In the study, therefore, compared with chicken feathers, human hair is considered a better natural absorbent to be used in oil spills. The chicken feather was still proven to be an effective absorbent in oil spill. It can also be concluded that in terms of absorption time, the longer the absorption time for human hair, the greater amount of oil was absorbed; whereas in chicken feathers, the longer the absorption time, the lesser the amount of oil is absorbed. Therefore, in chicken feathers, absorption time is inversely proportional to the amount of oil absorbed.
The third problem focused on the amount of oil left (g/L) by chicken feathers after the chicken feathers were applied. It is related with the amount oil absorbed. The greater the oil absorbed, the lesser the amount of oil left. The variation of the amount of oil left is affected by the transfer of setup from trays to glass containers. The conclusions were based only on one parameter, oil absorption capacity, since it is the property being tested by the researchers to show a significant difference among the different variables.
