Abstract

Blood albumin level testing is an important parameter in assessing nutritional status and liver function. In clinical laboratory practice, the use of serum or EDTA plasma as biological samples remains a subject of debate, particularly regarding the efficiency and accuracy of results. This study aims to compare albumin level test results using serum and EDTA plasma samples. Blood samples were collected from 20 participants and analyzed using spectrophotometry. The average albumin level in serum samples was 4.285 g/dL, while in EDTA plasma it was 4.280 g/dL. The Shapiro-Wilk normality test indicated a normal data distribution (p>0.05), and the paired t-test yielded a p-value of 0.804 (>0.05), indicating no significant difference between the two sample types. These findings suggest that EDTA plasma can serve as an alternative to serum in albumin testing, with the advantage of improved processing efficiency.

Abstract

This study investigates the phytochemical content and morpho-anatomical characteristics of Celosia argentea L. plants grown under different light intensities in the Embung Leuwi Padjadjaran area. Leaf samples were collected from shaded and unshaded locations to compare their responses to varying light conditions. Phytochemical analysis revealed that plants in higher light intensity areas tended to have increased levels of specific phytochemical compounds, which is crucial for the plant's defense mechanisms. Furthermore, the research found morphological and anatomical differences, such as greater leaf thickness and a lower stomatal density in unshaded plants. Conversely, shaded plants exhibited higher chlorophyll content and larger leaf areas, which are adapted to low-light environments. The study concludes that varying light intensity significantly influences the morpho-anatomical features and phytochemical composition of Celosia argentea L., with shaded conditions promoting adaptations for light capture and unshaded conditions increasing certain phytochemicals and leaf thickness.

Abstract

In the learning process, teaching materials and LKPD are needed to train students' abilities in learning. However, the teaching materials used are not yet appropriate due to the lack of material in the textbooks, in addition, the number of textbooks is still limited, resulting in less effective learning. This will certainly be less effective learning because the textbooks or printed books provided by the school do not match the number of students. This supports the LKPD research which will later become one of the new teaching materials by teachers and students because by using LKPD, learning time can be optimized well and by using LKPD students will be easier in the learning process. The purpose of this study is to produce LKPD Based on Problem Based Learning (PBL) on the material of transport and exchange of substances in humans for SMA/MA which is valid and practical. The development research uses the 4D model. This model has four stages of development, namely the define , design , develop and disseminate stages . This research was conducted until the develop stage , namely the validity test and practicality test. The assessment instruments carried out at this stage consisted of validity and practicality questionnaires, this validity questionnaire consisted of content feasibility, language, didactical, and graphical, while the practicality questionnaire consisted of ease of use, benefits. The data were analyzed using percentage techniques and processed using descriptive analysis or determining the highest score and the final value of validity and practicality. Based on the results of the research test, the developed LKPD is very valid with a value of (89%), the results of the practicality test by 2 biology teachers on the developed LKPD are very practical (92%), and the practicality of 31 students is very practical (87%). Based on the results of the validity and practicality tests, it can be concluded that the student worksheet (LKPD) based on problem based learning (PBL) on the material of transport and exchange of substances in humans for phase f of SMA 1 Akabiluru Kab. Lima Putuh Kota which was developed is very valid and practical.

Abstract

This study discusses the Development of Ecopedagogy Based Modules to Optimize Pancasila Student Profiles at JHS Sangen 01 Madiun. This study uses the Borg and Gall development with 10 stages, but in this study it only uses up to stage 8. Ecopedagogy-based modules must meet valid, effective and practical criteria. The results of the validity test with 3 validators obtained a result of 88.6 with a very decent category. The results of product effectiveness as seen from the achievement of learning outcomes and testing using independent sampling t-tests obtained results (6.687 > 1.708), so that the ecopedagogy-based module was declared effective. Relative effectiveness obtained results of 59.11% have a medium effectiveness category. The results of the practicality of ecopedagogy-based modules using student response questionnaires obtained 90.16% results which were considered very practical.

Abstract

Critical thinking skills are one of the essential 21st-century competencies that students must possess. However, in practice, during classroom learning at SMAN 17 Medan, students’ critical thinking skills are still relatively low due to the teacher-centered learning model being used. Therefore, a learning model that can encourage students to think critically is needed, one of which is the Problem-Based Learning (PBL) model.This study aims to determine the effect of the Problem-Based Learning model on students’ critical thinking skills. The research employed a quantitative method with an ex post facto research design, using a One Group Pretest-Posttest design. The sampling technique applied was purposive sampling. The research sample consisted of two classes, namely Class X-7 and Class X-8, both of which were treated with the same learning model, Problem-Based Learning, with a total of 70 students. The research instrument used to measure students’ critical thinking skills was an essay test. The results showed that the critical thinking skill scores in Class X-7 were 81.47 and in Class X-8 were 81.18. Data analysis using the paired sample t-test showed a significance value of 0.00 (Sig. < 0.05). Based on the results, it can be concluded that the implementation of the Problem-Based Learning model has a significant effect on the critical thinking skills of tenth-grade students in the subject of ecosystem components and their interactions at SMAN 17 Medan.

Abstract

The increasing pollution of rivers due to domestic activities and urbanization highlights the importance of biology-based water quality monitoring. This study aims to assess the water quality of the Genteng River (Kalimas) in Surabaya using the biotilik method with macroinvertebrates as bioindicators. The research was conducted descriptively with a mixed quantitative and qualitative approach. Data were collected through observation, sampling, and identification of macroinvertebrates based on the Biotilik guidelines. The identification results showed that the species composition was dominated by organisms tolerant to pollution. The average biotilik score of 1.5 classified the water quality in the Heavily Polluted category. These findings reflect a severely degraded river ecosystem. This study holds great potential to be utilized as contextual learning material in project-based Biology education, aiming to enhance students’ environmental awareness and critical thinking skills.

Abstract

The Mentawai Islands, located west of mainland West Sumatra, are part of popp Sumatra Province. The Mentawai people are the indigenous people of the islands and are renowned for their traditional healing practices, practiced by the "gadai mulaggek" (sagei mulaggek). Few published studies on Mentawai plant medicine have been published, most of which indicate that Zingiberaceae is one of the most widely used families. This study examines the traditional knowledge of Zingiberaceae among the Mentawai people of Saumanagnyak Village. Shamans or "gadai mulaggek" were interviewed directlly to obtain firsthand information about treatments using plants from the Zingiberaceae family. This study indicates that six species of Zingiberaceae are used in traditional Mentawai medicine
