Abstract

Kefir is a fermented milk product that is processed through fermentation of kefir granules. The objectives of this study are: 1. To analyse the effect of young coconut extract concentration on total microbes, ethanol and pH value of skimmed milk kefir. 2. To analyse the sensory test results of skimmed milk kefir with young coconut extract concentration. The method used in this research is Completely Randomised Design (CRD) with the treatment of variations in the percentage of skimmed milk and young coconut extract, namely: 100% skimmed milk: 0% young coconut extract; 95% skimmed milk: 5% young coconut extract; 90% skimmed milk: 10% young coconut extract; 85% skimmed milk: 15% young coconut extract; 80% skimmed milk: 20% young coconut extract with 3 repetitions and obtained 15 experimental units. The data obtained were analysed by ANOVA (Analysis of Variant). The results showed that increasing the concentration of young coconut extract increased the total number of microbes. Total microbes ranged from 1.48 x 10⁸ to 2.17 x 10¹⁰. Increasing the extract concentration from 15% to 20% increased the alcohol content from 0.07% to 0.20. Increasing the concentration of young coconut extract also significantly decreased the pH value of kefir after fermentation, with the lowest pH value (3.18) at 20% concentration. The concentration of young coconut extract in skimmed milk kefir significantly affected colour, texture and taste.

Abstract

This study aims to measure the effect of using interactive e-books in enhancing students' mathematical representation skills on optics material in high school. Mathematical representation involves students' ability to use mathematical symbols, graphs, and formulas to solve physics problems, particularly in the concept of optics, which is often considered abstract. The research method used was a quasi-experiment with a pretest-posttest control group design. The sample consisted of two classes: an experimental class using interactive e-books as learning media and a control class using conventional methods. The results showed an improvement in mathematical representation skills in both classes, with the n-gain value of the experimental class being 0.604 and the control class being 0.557, both in the medium category. However, the experimental class demonstrated a more significant improvement compared to the control class, indicating that interactive e-books are more effective in helping students deeply understand optical concepts. The interactive features in the e-book, such as simulations and animations, provided a more engaging learning experience and helped students visualize abstract concepts. In conclusion, the use of interactive e-books has a positive impact on improving students' mathematical representation skills and can be considered an effective alternative learning medium, especially for science subjects that require better visualization and conceptual understanding.

Abstract

The purpose of this study was to determine the perception of physics teachers towards the four-tier diagnostic test instrument equipped with self-diagnosis sheet to identify students' misconceptions on linear motion material. The research method used in this study is a mixed method with Sequential Explanatory Design.  Data were collected first using a questionnaire and then analyzed using descriptive analysis. The questionnaire was distributed to 14 physics teachers and 96 high school students in Lampung Province. The results showed that teachers have a positive perception of the use of a four-tier diagnostic test instrument equipped with a self-diagnosis sheet feature to identify students' misconceptions on straight motion material.  The results showed that 87% of teachers had never identified students' misconceptions on straight motion material. The results also show that 90% of teachers only use the results of daily tests as a benchmark to determine the misconceptions experienced by students. Misconceptions in this straight motion material certainly affect the learning outcomes of students, it is known that only 46% of students reach the KKM on straight motion material. And the results of the questionnaire show that 95% of teachers have never identified the misconceptions of students on linear motion material to make and use any type of multilevel diagnostic test instrument because the teacher has no difficulty in making it. So an effort is needed to overcome these problems, namely by making valid, practical, and effective multilevel diagnostic test instruments.  Based on the results of the study, it can be concluded that a four-tier diagnostic test instrument equipped with a self-diagnosis sheet is needed to identify students' misconceptions on linear motion material.
