Abstract
This investigatory project was conducted to prove if nipa palm fruit husk, distilled water, Ferrous Sulfate and gum Arabic can produce an ink that can be substituted to commercial ink. In conducting the experiment, the researchers gathered nipa fruits, these were cut into small portions and weighed into 200 grams. The reduced fruits were soaked in a mixture of 100ml distilled water and 1 gram Ferrous Sulfate (FeSO4) as solvent, vinegar, and salt. Theset-up was boiled for one hour. After boiling the mixture was filtered to separate the black filtrate from undissolved particles. On a laser bond paper the ink produced was tested after being refilled to a pen and was compared to other synthetic commercial ink available in the market. The conductivity and transmittance time , drying time and luminance and adhesion were tested and compared. Results of the test showed that the experimental ink with a proportion of 200 grams nipa palm fruit husk, 100 ml distilled water, 1 gram ferrous sulfate and ½ tablespoon of salt and ½ tablespoon of vinegar produced an output with the highest conductivity and transmittance time, drying time and luminance and adhesion. With the cost of production much lower than that of a commercial ink and having no significant difference in the mean property to the commercial ink the Nipa Palm Fruit Husk Ink proved to be more economical to produce.
