Abstract

Penyakit Parkinson merupakan gangguan neurodegeneratif progresif yang ditandai oleh penurunan dopamin di otak yang menyebabkan gangguan gerakan dan gejala non-motorik. Cannabis sativa diketahui memiliki senyawa aktif seperti THC dan CBD yang berpotensi meringankan gejala Parkinson. Namun, legalitas dan aspek etis penggunaan C. sativa masih menjadi perdebatan di Indonesia. Penelitian ini bertujuan untuk mengidentifikasi alternatif tumbuhan dari famili Cannabaceae yang berkerabat dekat dengan C. sativa dan berpotensi memiliki efek terapeutik serupa. Penelitian dilakukan menggunakan pendekatan in silico melalui analisis filogenetik berdasarkan penanda gen kloroplas matK terhadap 44 spesies Cannabaceae. Hasil analisis menunjukkan bahwa C. sativa berkerabat dekat dengan genus Humulus dan membentuk klad monofiletik. Humulus lupulus diketahui mengandung senyawa bioaktif seperti xanthohumol dan β-asam yang memiliki aktivitas antioksidan dan neuroprotektif. Dengan demikian, H. lupulus berpotensi dikembangkan sebagai alternatif non-psikoaktif C. sativa dalam terapi pendukung penyakit Parkinson, meskipun penelitian lanjutan tetap diperlukan.

The purpose of this study was to study the effectiveness the mixture of a IPA glyphosate + methulfuron methyl with two ratios of 24:1 and 36:1 against Ageratum conyzoides weeds. The study was conducted in Experimental Field Faculty of Agriculture, Tanjungpura University in January - March 2019. The research was arranged in accordance with the Randomized Group Design. Data analysis using probit analysis continued with combination index calculation. The results showed that the combination index of 24: 1 and 36: 1 were 0.84 and 1, respectively, the both ratio of mixed herbicide were not antagonistic to Ageratum conyzoides.Keywords: Ageratum conyzoides, glyphosate, methulfuron methyl, mixed properties

Abstract

Game-based learning has been widely developed as an instructional approach to enhance student engagement. One of its implementations takes the form of board games, which offer interactive and hands-on learning experiences. However, studies specifically examining their application to complex biology topics, such as the immune system, remain limited. Furthermore, few studies have simultaneously examined the effects on conceptual understanding and cognitive anxiety. Therefore, this study aims to analyze the impact of using board games on students’ mastery of immune system concepts and cognitive anxiety. This study employed a quasi-experimental design involving an experimental group (n = 30) and a control group (n = 32). Research instruments included a conceptual mastery test and the cognitive test anxiety scale (CTAS) questionnaire to measure students’ cognitive anxiety. The data were analyzed using inferential statistical tests and correlation tests to examine the relationships among the variables. The results of the study show that there were no significant differences in conceptual understanding or cognitive anxiety between the two groups, nor was a significant relationship found between the two. These findings suggest that the use of board games with complex subject matter does not always have a significant impact on cognitive or affective outcomes, although they hold the potential to promote a more positive learning experience

Abstract

Stress in studying is a common experience among undergraduate students, especially in courses that require intensive understanding such as basic biology. This study aims to identify factors that influence students' perceptions of stress. This study used a modified version of the academic stress scale developed by Bedewey and Gabriel (2015) with an internal consistency reliability of 0.7 (Cronbach's alpha). We added several statements to make them relevant to students' conditions and several open-ended questions to strengthen the data. The survey was distributed to three universities in the Papuan region with a total of 60 respondents. Participants were second- and fourth-semester students enrolled in basic biology courses. Descriptive statistics were used to analyze the students' experiences. The results showed that half of the students experienced academic stress primarily due to anxiety about course grades. Other major stress factors include feeling overwhelmed by the workload, difficulties with self-management, and limited knowledge about the learning strategies they should use. Non-academic stressors included personal and economic problems, as well as issues related to the personality of their lecturers. Students' perceptions of learning stress were in the moderate category. These findings suggest that excessive workload and poor self-management increase academic stress and may contribute to cognitive overload. Therefore, teaching strategies that consider student workload and develop self-regulation in students have the potential to reduce learning stress and improve academic well-being in biology courses

Abstract

The cheetah (Acinonyx jubatus) possesses morphological specializations that support high-speed locomotion, while its phylogenetic position within the family Felidae has been supported by molecular studies. This study aims to evaluate the ability of partial cytochrome c oxidase subunit I (COI) fragments to reconstruct the phylogenetic placement of A. jubatus using an in silico approach. The study employed a computational molecular phylogenetic design with purposive sampling from GenBank, comprising 32 COI records—29 from Felidae and three non-Felidae outgroups within Feliformia. The sequences were aligned using MUSCLE in MEGA11, then analyzed using Maximum Parsimony, 1,000 bootstrap repetitions, the Consistency Index (CI), and the Retention Index (RI). The final 275-bp alignment contained 87 conserved positions, 188 variable positions, and 173 parsimony-informative characters; A. jubatus was placed within the Felidae ingroup with a CI of 0.429 and an RI of 0.531. These results indicate that the partial COI is effective for recovering family-level phylogenetic signals, while also providing an analytical basis for the integration of multigene data in more detailed phylogenetic studies.

Abstract

This study aims to validate a research‐skills assessment instrument for pre-service science teachers using Rasch modeling to evaluate reliability, item fit, and unidimensionality. The instrument was designed to measure the extent of research skills among undergraduate students in science education programs. A cross-sectional survey was conducted with 114 participants recruited through quota sampling from several universities in Riau, Indonesia. Respondents completed a 40-item research-skills instrument. Data were analyzed with the Rasch model using Winsteps version 3.73. The results indicate satisfactory internal consistency (Cronbach’s alpha = 0.75), excellent item reliability (0.97), and acceptable person reliability (0.75). Rasch diagnostics further support the unidimensionality of the instrument, indicating that the items predominantly measure a single latent construct of research skills. These findings provide evidence for both the reliability and construct validity of the instrument within this population. Practically, the validated instrument can be used by higher education institutions to diagnose and monitor the research competencies of pre-service science teachers and to evaluate the effectiveness of research-oriented instructional interventions. By employing Rasch analysis, this study enhances the precision and defensibility of measurement in the context of research-skills assessment in Indonesia, offering a foundation for ongoing refinement and wider application in similar educational settings
