This project entitled "Utilization of Mulberries Extract as an Alternative Ink for Markers* aimed to develop an altemative ink source for markers out of locally available mulberry fruits or rotten mulberries that are usually put to waste when no longer appropriate for food consumption. The process involves extracting the fruit juice of the mulberry fruits through boiling/steaming, blending, and mixing with binding agents and solvents such as Gum Arabic and Alum. The use of fruit juice of the mulberry fruits in the study secks to prove that there is an alternative way of making ink made up of fruit extracts as an organic pigment for markers. This innovation secks to help the marker manufacturing industry lessen the cost of raw materials, save the cost of production, and convince that organic inks such as mulberries extract as an alternative ink for markers are way better than non-organic and synthetic inks used in markers in the market or industry. The use of available mulberry fruits or rotten mulberries in this study promotes the idea of recycling and conversion from waste to by-products. The produced mulberry ink for markers was proven to be useful and effective as an alternative ink for markers used for drawing, writing, or labeling. The acceptability performance of the produced mulberry ink for markers was evaluated by a group of experts in the field of printing and fine arts in terms of functionality, aesthetics, workability, safety, and saleability. Evaluators were composed of three (3) faculty/print professionals and seventeen (17) students from Graphic Arts and Printing Technology. The mean ratings of the evaluation in the criteria of the project are 4.28 for functionality, 4.28 for aesthetics, 3.98 for workability, 3.95 for safety, and 4.23 for saleability. The functionality and aesthetics of the project were proven to have the highest rating in the innovation of utilizing the mulberries as an alternative marker ink for extract. The produced ink is found to be user-friendly and eco-friendly, and its ink consistency is considered an alternative ink for markers. -- Author's abstract.
