THE EFFICACY OF PINEAPPLE JUICE, VINEGAR, AND COCONUT OIL-BASED PEN INK ERASER

Abstract

This study aimed to utilize the citric and oxalic acids found in pineapple (Ananas comosus) juice, the acidic properties of vinegar, and the cleaning properties of coconut oil to develop an alternative pen ink eraser. An experimental research method was employed in this study. A survey was conducted among ten (10) respondents using an evaluation criterion adapted from Lapina et al. (2015), where a rating of 1 represented the lowest effectiveness (ink stain not removed) and a rating of 5 represented the highest effectiveness (ink stain completely removed). The results showed that Trial 4 achieved a mean rating of 3.8, which was the highest effectiveness score among all trials. This indicated that the alternative ink eraser was able to almost remove the ink stain. In comparison, the correction tape used as a reference obtained a rating of 5, indicating complete removal of the ink stain. The findings demonstrated that the alternative ink eraser exhibits potential in removing ink stains, as supported by both experimental and survey results. Although it did not fully match the effectiveness of commercial correction tape, further refinement and additional testing may enhance its performance, offering a practical alternative for maintaining clean and neat documents.
