Abstract

This study focuses on examining the properties of phenolic and flavonoid compounds that result from the distillation of beluntas (Pluchea indica L) leaves, with changes in temperature and distillation pressure as the variables.  A randomized block design method used in this reserach to arranged factorially with two factors, namely distillation temperature and distillation pressure. Data is displayed in the form of graphs and tables. The research results show that the variables of pressure and temperature of the distillation have a tendency to influence the bioactive levels of the distillation products analyzed. The pressure factor and increasing distillation temperature have a tendency to influence the levels of polyphenols and vitamin C, namely increasing the levels at a pressure of 14.5 psi, on the other hand reducing the levels of polyphenols and vitamin C at a pressure of 29 psi. Increasing distillation temperature does not tend to increase flavonoid levels at high pressure, while increasing two distillation factors, namely temperature and pressure, appears to increase the antioxidant capacity of distillation products.

Abstract

This study aimed to examine the mathematical communication skills of female students in solving derivative problems in the eleventh grade at SMA Negeri 1 Sigi. The research followed a qualitative approach with a descriptive design. The study sample consisted of three female students selected based on a questionnaire focusing on feminine gender traits. Data were collected through written tests, interviews, and direct observation of the subjects. The dependability and credibility techniques were used to ensure the quality of the research findings. Data analysis involved three stages: data condensation, data presentation, and drawing conclusions. This study contributes to the existing literature by addressing the gap in understanding the mathematical communication skills of students with feminine gender traits, specifically in the context of solving derivative problems. The uniqueness of this study lies in the use of a feminine questionnaire for subject selection and the integration of mathematical language with everyday language and physical gestures in the evaluation of mathematical ideas. The findings revealed that female students with feminine gender traits demonstrated proficiency in all indicators of mathematical communication skills, including: (1) the ability to communicate their mathematical thoughts coherently and clearly to their peers and teachers; (2) effective use of mathematical language, such as numbers, letters, symbols, charts, graphs, and logical connections, in conjunction with everyday language and physical gestures when presenting, solving, and evaluating mathematical ideas during interactions with others; and (3) the capacity to explain mathematical ideas, situations, or relationships in written form. These results suggest that approaches combining mathematical language with physical interaction and everyday language can enhance the effectiveness of mathematical communication. The findings of this research can be utilized as a foundation for developing more inclusive and adaptive teaching strategies that consider gender differences in mathematics education.

Abstract

The purpose of this study was to describe the concept understanding ability of students in solving the problem of two-variable linear equation system. The method used is descriptive qualitative research. The subject of this research was 3 students taken from 26 students of class VIII SMPN 1 Balaesang. The results showed that the concept understanding of high mathematics ability students in restating concepts can restate concepts well using their own language, identify examples and non-examples and classify objects according to certain properties in accordance with the concept that can make mathematical modelling and determine equations and use the right solution steps according to the concept algorithmically. The concept understanding of medium ability students in restating concepts has been able to state concepts using their own sentences, identify examples and non-examples and are still lacking in classifying objects according to certain properties in accordance with the concept. The concept understanding of low ability students has not been able to achieve all indicators of concept understanding. Therefore, concept understanding is very important to be mastered by every student and the role of the teacher in facilitating the ability of each student.

Abstract

This research aimed to assess teachers' understanding of the Technological Pedagogical Content Knowledge (TPACK) structure and investigate whether TPACK components differ based on gender characteristics. The research method used was a cross-sectional survey, a quantitative approach aimed at examining a condition at a specific point in time and exploring relationships between variables. Respondents were randomly selected from 102 teachers spread across Lombok Island, comprising 48 female teachers and 56 male teachers. The research instrument utilized a TPACK questionnaire measuring CK, PK, TK, TPTCK, and TPCK, adapted from Liang et al., 2013. The analysis results indicated that teachers demonstrated a solid understanding of Content Knowledge (CK) and Pedagogical Knowledge (PK), signifying a strong grasp of the taught material and effective teaching techniques. However, concerning Pedagogical Content Knowledge (PCK), their understanding of how to teach specific content required further attention. Nevertheless, they exhibited a robust understanding of Technological Knowledge (TK), Technological Pedagogical Content Knowledge (TPTCK), and Pedagogical Content Knowledge (TPCK), although the level of understanding in TPCK was slightly higher than TPTCK. Meanwhile, the gender-based analysis showed significant differences in TPACK understanding between the genders in the TK, TPTCK, and TPCK components, but no significant differences were observed in the PK, CK, and PCK components. This highlights the importance of understanding gender differences related to specific aspects of technology, education, and content knowledge. Further research or in-depth analysis is needed to comprehend the underlying factors causing these differences and their implications within the educational context and curriculum development.
