Abstract

The purpose of this study was to determine the factors that cause reading difficulties in high school students. The type of research is descriptive qualitative research. The data collection technique is by using interview techniques. The subjects used in this study were teachers in class V. Based on the results of the study, it can be concluded that the factors that influence students' reading difficulties are influenced by the students themselves (internal) and there are also influences that come from outside the students (external). The internal factors are the student's lack of interest in reading, the student is difficult to teach and often does not go to school. External factors are the lack of support or the role of parents and the influence of online learning during the Covid-19 pandemic which requires students to study at home with minimal direct interaction with teachers, which results in a lack of stimulation and assistance in the reading learning process.

Abstract

Edible films are thin layers used to coat food products and can be consumed along with the product itself. Previous studies have utilized purple yam starch as a base material for edible films; however, these films exhibit limitations in terms of mechanical and barrier properties. This study aims to utilize purple yam mucilage to improve the mechanical and barrier properties of purple yam starch-based edible films.  The experimental design employed a randomized complete block design (RCBD) with five ratios of water to purple yam mucilage (1:0.5, 1:1, 1:1.5, 1:2, and 1:2.5). The results showed that increasing the proportion of purple yam mucilage improved the mechanical and barrier properties of the edible films, while reducing their solubility in water to as low as 33.23%.  The best film characteristics were achieved at a ratio of 1:2.5, with a thickness of 0.14 mm, a compressive strength of 3.73 × 10⁻⁴ MPa, a water vapor transmission rate (WVTR) of 21.94 g/m²·day, a transparency value of 8.33 %T/mm, and a solubility of 33.23%.
