Abstract

Infertility is a reproductive health issue that affects many couples of reproductive age, and in males it is frequently associated with decreased sperm quality. One of the major contributing factors to impaired sperm quality is oxidative stress, which results from an imbalance between the production of reactive oxygen species (ROS) and the antioxidant defense system. This imbalance can damage sperm cell membranes, alter DNA integrity, and disrupt the process of spermatogenesis. This study aimed to review the potential of Cinnamomum zeylanicum in improving sperm quality through the regulation of oxidative stress. A literature review approach was employed by examining scientific publications obtained from Google Scholar and ResearchGate within the last ten years. Relevant studies were analyzed descriptively based on research design, observed sperm parameters, and the reported findings. The review indicates that Cinnamomum zeylanicum contains several bioactive compounds, including flavonoids, polyphenols, and cinnamaldehyde, which exhibit strong antioxidant activity. These compounds may reduce oxidative damage and protect sperm cells, thereby potentially improving sperm parameters such as count, motility, and viability.

Abstract

Science education in schools faces various challenges, such as the dominance of teacher-centered lecture methods, a lack of integration between theory and practice, and limited learning facilities. These issues hinder students from developing critical thinking, collaboration, and adaptability to modern demands. This study aims to develop a Problem-Project Based Learning (P2BL) model as a solution to address these challenges. The model integrates the strengths of Problem-Based Learning (PBL) and Project-Based Learning (PjBL) to create contextual, practical learning experiences that encourage critical thinking among students. A Research and Development (R&D) approach with the ADDIE framework is employed to ensure the systematic development of the model. The P2BL model consists of five main components: syntax, reaction principles, social system, support system, and instructional as well as accompanying impacts. The syntax of this model includes stages such as problem definition, experimentation, planning, presentation, and evaluation, supported by multi-directional interactions between instructors and students, as well as collaboration among students. The research findings indicate that implementing the P2BL model enhances academic abilities, practical skills, and the development of attitudes such as teamwork, responsibility, and time management. With its relevance to the demands of the Industrial Revolution 4.0 era, the P2BL model offers a more interactive, effective, and adaptive learning alternative to improve the quality of Science education in schools.

Abstract

Asthma is a disease defined as chronic inflammation of the airways which is characterized by recurrent coughing and shortness of breath. Dermatoglyphs are the appearance of tendrils and tendril patterns on the fingers, palms, toes and soles. Dermatoglyph is used as an aid in the detection of a number of diseases that have a strong heritable basis and is also used to detect abnormalities. This study aims to analyze and compare the patterns of dermatoglyphics in asthma sufferers and non-asthmatics on the fingertips. This type of research is descriptive research with cross sectional sampling method. Samples were taken from the student population of the Faculty of Mathematics and Natural Sciences, Padang State University as many as 100 samples of fingerprint patterns. The results obtained showed that there was a significant difference in the number of arch fingerprint patterns of asthmatics compared to normal individuals. Seeing this significant difference in numbers indicates a possible link between fingerprint patterns and asthma phenotypes.

Abstract

Dermatoglyphics is a science that studies fingerprint patterns that can be inherited genetically. Fingerprint patterns can be divided into three patterns, arch, loop, and whorl. Observation of fingerprints is used to determine fingerprint patterns and the relationship between these patterns and the fields of health, education, and criminology. Left-handed is a term for people who predominantly use their left hand as their main hand to carry out daily activities. This research aims to determine the relationship between fingerprint patterns and individuals who tend to carry out activities with the left side of their body (left-handed). The type of research carried out was descriptive research with a cross-sectional sample collection method. The sample was taken from the 2019-2022 student population of the Faculty of Mathematics and Natural Sciences, Padang State University, totaling 100 individuals. The samples were taken in November and December. This research was carried out at the Genetics and Biotechnology Laboratory, Faculty of Mathematics and Natural Sciences, Padang State University. The results of this study show that the dominant fingerprint pattern found in the left-handed individual phenotype is 16 fingerprint patterns, while normal individuals have 5 arch fingerprint patterns. This shows that there is a link between the phenotype of left-handed individuals and dermatoglyphics.

Abstract

The high production of catfish (Clarias sp.) requires a sustainable seed supply, which is frequently constrained by the asynchronous gonad maturity of broodstock. Sperm preservation using young coconut water as a natural extender and glycerol as a cryoprotectant offers a viable solution to address this limitation. This study aimed to analyze the interactive effects of extender formulations and storage temperatures on the viability of catfish spermatozoa after four days of preservation. Semen was extracted by stripping from a single mature male broodstock weighing 3,000 g. The experiment employed a two-factor factorial Completely Randomized Design (CRD). A total of 30 experimental units consisting of 0.2 mL microtubes were used, including 27 units for the factorial treatment combinations and 3 unreplicated control units (100% young coconut water), with one control assigned to each storage temperature. The factorial treatments consisted of two factors with three replications: extender formulation (P1: 75% young coconut water + 25% glycerol; P2: 50% young coconut water + 50% glycerol; and P3: 25% young coconut water + 75% glycerol) and storage temperature (27°C, 5°C, and −20°C). Sperm viability was evaluated using 1% eosin staining and analyzed by two-way ANOVA (α = 0.05). The results showed that storage at 27°C and −20°C caused complete spermatozoa mortality (0% viability) across all extender treatments and the control. In contrast, storage at 5°C produced the highest sperm viability in treatment P1 (82.88%), followed by P2 (65.38%), while P3 and the control exhibited 0% viability. In conclusion, the combination of young coconut water and glycerol stored at 5°C effectively maintained the viability of catfish spermatozoa, with the formulation containing 25% glycerol (P1) identified as the optimum treatment for short-term preservation.
