| Summary, etc. |
The research study was undertaken to formulate an organic marker ink from waste pili pulp<br/>as the main source of pigment. In the production process, water and glycol were used for<br/>solvents whereas alum, gum Arabic, silica and hydrochloric acid were used as additives.<br/>In the process, the pili pulp wasfirst cut to pieces and ground to fine condition. The pigment<br/>was then harvested through use of ethanol and fumed silica. Spectrophotometry was used<br/>to analyze the extract, resulting in a level of light absorbency of 0.0164%, and Apricot was<br/>determined to be its color through visible analysis. After extraction the mixture was dried<br/>and powdered. Later on other additives and solvents were added. The ink samples were<br/>subjected to a series of laboratory evaluations, such as viscosity tests, visual color<br/>examinations, and spectrophotometric examinations as well as toxicity tests. The obtained<br/>evaluation results showed the ink with a viscosity of 91cP and a light brown color, but with<br/>less than 1 ppm heavy metals, and a light UV absorbing mark of 0.087%. In addition to<br/>this, the marker ink was evaluated by 18 students, 5 faculties, and 2 specialist according to<br/>seven points evaluation criteria provided by TAP. According to ratings given on a scale of<br/>1 to 5, the results reflected that the marker ink was highly acceptable in terms of<br/>functionality obtained an average 4.73. For the other categories the ratings were as follows:<br/>The workability got 4.67, the durability scored 4.63, the economy was placed at 4.57, the<br/>safety was assured 4.84, and saleability averaged 4.65. Also, the ink was deemed very<br/>acceptable in terms of aesthetics, having average score of 4.15. Overall the product got an<br/>average rating of 4.61 (Highly Acceptable) and it was indicated that the pulp of pili could<br/>be used as an alternative material for water based ink markers. |
