Hematocrit examination of the wintrobe method, where erythrocyte solids are obtained by a blood centrifugation process which is determined by the speed and time centrifugation factors. As the number of examinations increases, sometimes the accuracy of centrifugation is often ignored. The purpose of this study was to determine the effect of centrifugation time variations on the results of the Macro Method hematocrit examination in D3 Health Analyst Study Program students. The method used in this study was a quasi-experimental method to find out the effect of variations in playback time on the results of the hematocrit examination of the Wintrobe method. The results of this study were obtained F-counts (0.835) and Ftables (3.35). Hematocrit centrifugation of the 25 minute macro method obtained the lowest levels of 37.5% and the highest is 68%. Centrifugation for 30 minutes obtained the lowest levels of 35.3% and the highest 66%. And lastly carried out centifugation for 35 minutes obtained the lowest levels of 37% and the highest 49.5%. Based on the above conclusions can be used for 25, 30, and 35 minutes centrifuge.

The low activity and cognitive learning outcomes of Grade VIIIB MTs Aisyiyah students require innovation in learning by using cooperative learning models. This study aims to determine the increase in activities and learning outcomes in biology through the application of cooperative learning models of students team achievement division class VIIIB MTs Aisyiyah Sungguminasa Kab. Gowa. This type of research is Classroom Action Research which consists of two cycles. The subjects of the study were students of class VIIIB MTs Aisyiyah Sungguminasa Kab. Gowa. The research instrument was an observation sheet and a test. Data analysis techniques with qualitative descriptive statistical analysis for student activities and analyzed with quantitative descriptive statistical analysis for learning outcomes. The results showed that there was an increase in students' cognitive learning activities and outcomes namely from cycle 1 and cycle 2 with an average value of 46.71% and 85.5%. Thus, the conclusion of this research is the use of cooperative learning models of students team achievement division type can increase the activities and learning outcomes of students of class VIIIB MTs Aisyiyah Sungguminasa Kab. Gowa.

Abstract. One of the important things that must be considered by the teacher in the learning process is to know in advance the characteristics of students. Learning style modality is one of how students know and recognizes their personality in the learning process. The type of research used in this study was a survey using a qualitative descriptive approach. The population in this study were all high school students in class IX, Jeneponto Regency, for the 2021/2022 academic year. The samples in this study were students from SMA 9, SMA 10, and SMA 12 students in class IX. science specialization with a total of 67 students consisting of 20 male students and 47 female students. The instrument used in this study was the VARK questionnaire (Visual, Aural, Read, and Kinesthetic) developed by Neil D. Fleming. Data were analyzed using descriptive analysis with the acquisition of the percentage of each learning style possessed by students. The results showed that the modality of the learning styles of Jeneponto District Senior High School students was the Aural learning style. There is no difference in learning styles between male and female students. The dominant gender based student learning style is Aural. .Keywords: biology lessons, learning styles, gender.

Abstract Purpose: This study aimed to describe the learning styles of Health Analyst students at the Faculty of Public Health, University of East Indonesia, and to identify the dominant learning style modality that may influence their learning process and academic achievement.Research Methodology: This study employed a survey research design with a quantitative descriptive approach. The research was conducted at the Faculty of Public Health, University of East Indonesia, during the 2025/2026 academic year. The population consisted of all Health Analyst students, while the sample included 35 students enrolled in the Basic Microbiology course. Data were collected using the VARK (Visual, Aural, Read/Write, and Kinesthetic) questionnaire developed by Neil D. Fleming. The questionnaire was used to assess students’ preferred learning modalities. Data analysis was carried out descriptively by calculating the percentage distribution of each learning style category.Results: The results showed variations in students’ learning style preferences. Among the four VARK modalities, the auditory learning style was identified as the most dominant learning style among Health Analyst students. This finding indicates that students tend to learn more effectively through listening, verbal explanations, discussions, and other auditory-based learning activities.Conclusions: The study concludes that auditory learning is the predominant learning style among Health Analyst students at the Faculty of Public Health, University of East Indonesia. Therefore, learning strategies that emphasize oral communication and interactive discussions may improve learning effectiveness.Limitations: This study was limited to a relatively small sample and involved students from only one study program and course.Contributions: The findings provide useful information for lecturers and curriculum developers in designing instructional strategies that align with students’ learning preferences and support more effective learning in health science education.Keywords: Learning styles, basic microbiology, learning
