Abstract

The aim of this research was to find out the influence of single bulb garlic on sperm quality improvement in hyperlipidemia model of male mice. Male mice (Balb-C, 12 weeks, bw 215 g) were given high fat diet for 45 days until their body weight achieved 455 g. The mice were then divided into six groups. The mice in the first group (control group (N)) was fed with 7 g higrow pokphan 551 per day. The mice in the second group (control negative group) was fed with 7 g high fat diet (HFD), while the mice in the third group (control positive group) were treated with statin at dose of 0.91 mg. The mice in groups 4, 5, and 6 were treated with single bulb garlic extract at dose of 125 mg/kg bw, 250 mg/kg bw, and 500 mg/kg bw, respectively. On the 31st day, the male were dissected and cauda epididymis was taken and chopped in a sterile phosphat buffer saline (PBS) and observation conducted on sperm quality consisted of sperm count, sperm motility and sperm normality. The results indicated a significant increase in sperm count, motility and normality in mice treated with single bulb garlic extract at dose of 250 mg/kg bw.

Abstract

This study aims to analyze student responses to the use of a biochemistry e-module on carbohydrate material and its impact on learning independence. This quantitative descriptive research involved 40 students from the Biology and Chemistry study programs who had used the e-module. Data were collected through a questionnaire covering five indicators: ease of use, effectiveness of material delivery, level of interactivity, learning independence, and general response. The results showed that for the ease of use indicator, the carbohydrate e-module received an average response of "very good" with an average percentage of 83%. The effectiveness of material delivery scored 82.75%, while the level of interactivity reached 85.7%. However, the learning independence indicator had a lower average score (78.7%), indicating the need to strengthen self-learning motivation and encourage further exploration of additional information. The study concludes that the biochemistry e-module on carbohydrate material is effective in enhancing students' understanding but requires some improvements, such as adding a glossary feature and interactive elements to optimally support learning independence. The integration of technology in learning is expected to continue developing to improve the effectiveness of science-based education.

Abstract

This study aims to analyze the feasibility of an essay-based assessment instrument developed to measure university students’ critical thinking skills in a contextual learning setting with local cultural integration. The instrument was constructed based on critical thinking indicators proposed by (Ennis, 2011) and embedded within environmental science content and the Kenduri Sko cultural tradition. Five expert validators assessed the instrument using a validation sheet covering five aspects: content relevance, item construction, language clarity, practicality, and cultural sensitivity. The results show that all aspects received an average score above 3.80, with an overall feasibility percentage of 96.15%, categorized as highly feasible. In addition, qualitative feedback from validators recommended minor revisions in question instructions and refinement of the scoring rubric. Overall, the instrument is considered suitable for use as an authentic assessment tool in culturally contextualized learning in higher education. Further empirical testing and reliability analysis are recommended for broader implementation
