CRIZALDO, ISABELLE LEIGH ANGELA E_, PELORINA, EUNICE MAE L., AND RAMOS, LARA SOPHIA N. Production of Handmade Paper from the Fruit of Narra (Pterocarpus indicus) Tree. Research Study. (General Science Curriculum). Laboratory Science High School, College of Education, Cavite State University, Indang, Cavite. June 2019. Adviser: Dr. Agnes B. Alimboyoguen.

The study was conducted at Department of Science and Technology — Forest Products Research and Development Institute and at the Cavite State University from August 2018 to June 2019. Generally, this study aimed to produce handmade paper from the fruit of Narra. Specifically, this sought to determine the following: the physical properties of the handmade paper in terms of burst strength, tear resistance, tensile strength, and thickness: its sensory properties in terms of colour, texture, and odor; the level of acceptability of the product in terms of its sensory properties and general acceptability, and the best treatment in terms of physical properties.

There were four treatments used in the experiment which was composed of Ta (100% recycled paper), T, (10% fruit of Narra, 90% recycled paper), T2 (20% fruit of Narra, 80% recycled paper), and T; (100% fruit of Narra). The handmade papermaking process consisted of collection and preparation of materials, pulping, rinsing, disintegration, stock preparation and sheet forming, couching and pressing, and lastly, drying.

The data for the physical properties were collected at DOST-FPRDI using their corresponding machines. Meanwhile, the data on Sensory properties and the level of acceptability were gathered using a checklist and a Likert Scale, respectively, which were answered by 30 Grade 10 students of the Cavite State University- Laboratory Science High School. The researchers used Duncan’s Multiple Range Test for ANOVA to analyse the physical properties of the handmade paper. Moreover, Friedman Test for Analysis of Variance was used to analyse the physical characteristics of the paper. Percentage was also used to analyse the data gathered in this study.

Results revealed that among the physical properties, thickness was the only property which showed significant differences among the treatments. Meanwhile, in terms of the sensory properties, odour was found to be not significantly different among the treatments used. There was no data available for T;’s physical properties due to machine constraint. Moreover, in terms of colour, To, Ti, and T2 were described as white smoke and Ts as light oak. In terms of texture, To and T were smooth and T2 and Ts were rough. Based on the findings, the evaluators liked all the treatments in terms of odor. Furthermore, an overall response of “Like Very Much” was given Ty and T; while Ts; obtained a response

of “Like” in terms of color. Meanwhile, in terms of texture, To and T: obtained an overall response of “Like Very Much” while T> was judged with “Like” and T obtained a general response of “Neither Like or Dislike”. Tp was found to be “Highly Acceptable”, T, and T> were “Acceptable”, while T was “Moderately Acceptable” in terms of the final products” general acceptability. Lastly, T was found to be the best treatment in terms of the physical properties.
