Water hyacinth As Boardmarker Ink

Preface

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.

Growth and development of water hyacinth can occur very quickly, because hyacinth is adaptable. Hyacinth will be more easily developed during the rainy season, and will decrease during the dry season. Salt levels can also slow the growth of water hyacinth. Water hyacinth also contains tuber plants, so if the water hyacinth is cleared but not until the root, water hyacinth will remain alive and grow.

Various efforts have been done by the government in eradicating water hyacinth by using pesticides or disinfectants. This may work in the first place, but over time the water hyacinth will boost its immune system, so that pesticides or disinfectants will not work again to eradicate water hyacinth. Staking the stem alone also has no effect, because the tubers in the water hyacinth will continue to spread and survive.
The existence of water hyacinth has been regarded as a weed, and pesticide eradication is not very influential, hence needed alternative way that is by utilizing water hyacinth as ink marker at by taking carbon present in water hyacinth to be made marker.

On the other hand boardmarkers are a major requirement in education. Learning activities will not be complete without a boardmarker, especially if the teacher wants to explain something to his students. Both permanent markers and colored markers are the primary needs of various circles. Markers have some content such as Xylene or Volatile Organic Compound (VOC) that are harmful to the body such as disturbing breathing, dizziness, headache, short-term memory loss, and so on.

Looking at the facts above, then in this study focus on the effectiveness of water hyacinth as ink markers. So it is expected to provide an alternative in overcoming the number of water hyacinth that is as weed, especially in the city of Surabaya and make alternative materials safer for health.
Specific research purpose include:
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.
Tools and Materials
To do this activity required tools to simplify the experimental process.
The tools used are matches, scales for weighing quantities, measuring cups to measure the amount of material needed, filters to filter the water hyacinth and ink solution, blenders for mixing the ingredients, spoons to stir the solution, the pipette for picking up the material, and sealed container for storing water hyacinth. While the materials used in this study is water hyacinth, alcohol, resin, aquades and propylene glycol.

Hyacinth Making Procedures
The work procedure of making water hyacinth first is to prepare tools and materials to be used, ie water hyacinth, containers that are resistant when burned and matches. If the water hyacinth has been burned and become powders, strain so unburned particles can be separated, then enter water hyacinth into a sealed container such as plastic.

Ink Making Procedure On Markers Of Hyacinth
The working procedure of making ink markers on the first water hyacinth is to prepare the tools and materials to be used, then weigh the mass of water hyacinth in accordance with some formula that will be compared later (ink 1, ink 2, and ink 3). Measure resins, alcohols, aquades, and propylene glycols, then pour them all into a blender. After mixing, filter the filtrate water hyacinth and store the ink in a sealed container. The finished ink will amount to 150 ml.
Results
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.

In this study water hyacinth is used as a marker material. The experiments were carried out using different doses of preparation to obtain the material composition and how to make the marker ink from the right hyacinth so it can be produced.
making ink
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:

Ink 1 15 5.5 35 45 3.5
Ink 2 15 5.5 45 35 3.5

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.

Hyacinth Ink Viscosity Test
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.

Ink 1 1,297
Ink 2 2,725
Control Ink 1,117

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.

Hyacinth Ink Chromatography Test
In this chromatographic test used ink markers as a quality comparator. Chromatography test aims to know the Rf in ink. Test is done by dripping ink on iron plate then irradiated by artificial UV.

Discussion
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. Many people complain about the existence of water hyacinth, especially rural people who make waters such as rivers as their main transportation infrastructure.

Growth and development of water hyacinth can occur very quickly, because hyacinth is adaptable. Water hyacinth also contains tuber plants, so if the water hyacinth is cleared but not until the root, water hyacinth will remain alive and grow so as to disturb the aquatic ecosystems. This is in line with research Istighfaroh (2013), which states that water hyacinths have a negative effect on the environment that is to abandon the aquatic system so that the aquatic ecosystem is hampered which will eventually harm the community.

On the other hand markers are very commonly used especially during the teaching process. Based on Widodo’s (2016) research, various problems are found in the use of markers, ie easy lid, difficult to refill, end of boardmarker easily damaged, and ink often scattered through the end of markers after refill. In addition, the material contained in the ink thinners marker is xylene is a harmful material for health that contains very small toxic particles so it is very easy to enter the respiratory tract.

Worn markers will usually be discarded and then use a new one, but this adds to the amount of plastic waste in Indonesia. The Directorate General of Human Settlements also stated in 2015 that the more boardmarkers used will have an impact on the environment, especially plastic waste. Plastic waste production in Indonesia reaches 5.4 million tons per year.

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.


using 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.
