BACKGROUND OF THE STUDY

• Ink is a liquid or paste containing dyes or pigments used for writing or drawing purposes.
• Synthetic inks often contain toxic metals and are expensive to produce, posing environmental and affordability challenges
• Malabar spinach is abundant and rich in betalain pigments, making it suitable for ink production.
• Purple sweet potato leaves contain anthocyanin pigments, making them another viable plant source for ink.
• Properties such as drying time, odor, color, consistency, and stability will be assessed to ensure ink quality.

Statement of the Problem

This study attempted to determine the effectiveness of Sweet Potato Leaves and Alugbati extract as an ingredient for marker ink. Specifically, it aimed to answer the following questions: 1. What is the quality of the ink produced from sweet potato leaves & alugbati in terms of: a) absorption, b) consistency, c) color, d) stability?

Statement of the Problem

2. Is there a significant difference between the sweet potato leaves and alugbati ink and the standard or commercial ink in terms of: a) absorption, b) consistency, c) color, d) stability?

Scope and Limitation

Abundance, affordability, and availability of the plants in the Philippines

Addition of preservatives and quality enhancers (water and isopropyl alcohol)

Focus on two plant sources: sweet potato and malabar spinach.

Time constraints

Focus restricted to ink preparation, testing, and application

Budget limitations

Hypothesis

1. There is no significant difference between the produced ink from sweet potato leaves & alugbati and the commercially available ink in terms of: a) absorption, b) consistency, c) color, d) stability.

Methodology

• The researchers employed a descriptive-experimental research design to investigate the quality of sweet potato leaves (Ipomoea batatas L.) and Malabar spinach fruits (Basella alba L.) as organic ink alternatives.

• The study involved a series of experimental processes and comprehensive explanations to provide a thorough understanding of the research.
