Water hyacinth is a water plant with the characteristics of hollow stems and rooted sert. Water hyacinth is often regarded as a weed because of its rapid vegetative growth and masking the underwater life process from the sun, causing a decrease in the oxygen solubility rate in the waters. Many people complain about the existence of water hyacinth, especially rural people who make waters such as rivers as their main transportation infrastructure.
1. Knowing that hyacinth plants can be used as an ink boardmarker;
2. Know the characteristics of boardmarkers ink made from water hyacinth;
3. Knowing that ink from water hyacinth is feasible to produce
4. Know the right formula to make ink markers from water hyacinth.
This research utilizes carbon content in water hyacinth. Society has been assuming that water hyacinth is a pest or weed that needs to be eradicated because it disrupts the river ecosystem. Extermination with pesticides will be successful initially, but water hyacinth will boost its immune system so pesticides will not affect the water hyacinth.
The process of making ink markers first begins with the burning of water hyacinth. Once it is burned and has become, it is put in a closed container so that it does not fly. Next blender, beaker glass, and measuring cups are prepared to measure the ingredients used. Here are the ingredients and formulas used:
|water hyacinth (ml)||Resin (ml)||Alkohol (ml)||Aquades (ml)||Propilen Glikol (ml)|
The measured materials are blended until well mixed, then blender is poured into the beaker glass after going through the screening process. The filtrate is then poured into a bottle of markers, and wait a while for the ink to propagate and be used. The remaining ink is then stored in a sealed container.
In testing viscosity is used ink markers as a quality comparator or control. The viscosity test aims to determine the degree of viscosity of the markers. The viscosity of the ink or viscosity is a matter of concern in the manufacture of ink. Ink should not be too thin and should not be too dense.
From the test results, the viscosity of ink 1 is the most approximate ink with formula 15 ml water hyacinth, 5.5 ml resin, 35 ml alcohol, 45 ml aquades, and 3.5 ml propylene glycol.
From the test results it can be concluded that Rf ink 1 is the most approximate ink with formula 15 ml water hyacinth, 5.5 ml resin, 35 ml alcohol, 45 ml aquades, and 3.5 ml propylene glycol.
In this case hyacinth plant is an alternative to safe ink marker replacement. Hyacinth plant mixed with the materials then filtered, so that the results obtained in the form of ink.
Based on the results of viscosity and chromatography test it can be concluded that ink 1 with 15 ml water hyacinth, 5.5 ml resin, 35 ml alcohol, 45 ml aquades, and 3.5 ml propylene glycol are the most similar inks to comparable inks. Ink markers from water hyacinth are eligible to be produced because of the similarity with ordinary and safer ink, as well as the raw materials obtained very easily.
The conclusion of this research is water hyacinth can be utilized as ink marker material.
