Abstract

Haemonchus contortus remains one of the most pathogenic gastrointestinal nematodes in goats, causing substantial productivity losses in small ruminant farming. The increasing resistance and residue concerns associated with synthetic anthelmintics highlight the need for safer, plant-based alternatives. This study aims to review the potential of Moringa oleifera leaves as a natural anthelmintic for controlling Haemonchus contortus infections in goats. A non-systematic literature review was conducted by screening scientific articles published between 2019 and 2024 through Google Scholar using keywords related to alternative natural anthelmintics, control of goat parasites, Haemonchus contortus infection, Moringa oleifera, and plant phytochemical compounds. Relevant in vitro and in vivo studies were analyzed descriptively to evaluate the plant’s phytochemical profile, mechanisms of action, and effectiveness. Findings indicate that Moringa oleifera leaves contain tannins, saponins, flavonoids, alkaloids, and terpenoids that inhibit egg hatching, disrupt larval development, and impair adult worm survival. In vitro studies consistently demonstrate high ovicidal, larvicidal, and vermicidal activity, with inhibition rates comparable to albendazole at higher concentrations. In vivo results also show significant reductions in fecal egg counts (FEC), particularly at doses of 200–400 mg/kg body weight, without reported adverse effects. These outcomes underline the effectiveness and safety of Moringa oleifera leaves as a promising natural anthelmintic. In conclusion, Moringa oleifera represents a viable, environmentally friendly option for integrated parasite control in goats, particularly for reducing infections caused by Haemonchus contortus. Further standardized dosing studies and long-term evaluations are recommended to optimize its practical application in small ruminant health management.

Abstract

Hemophilia is an inherited X-linked recessive bleeding disorder characterized by deficiency of coagulation factors and commonly presents with hemarthrosis that may lead to permanent joint damage if diagnosis is delayed. This report aims to describe a case of recurrent hemarthrosis that led to the diagnosis of previously unrecognized hemophilia B. We report a 3-year-old boy with progressive swelling and pain of the left knee following minor trauma and surgical intervention, with a history of easy bruising and prolonged bleeding after circumcision. Laboratory evaluation showed prolonged activated partial thromboplastin time with normal prothrombin time and platelet count, and coagulation factor assay revealed factor IX activity of 1.2%, consistent with moderate hemophilia B. Recurrent hemarthrosis in this patient was the key clinical manifestation that prompted further diagnostic evaluation. This case highlights that recurrent or persistent joint bleeding in children, especially in the absence of a clear family history, should raise strong suspicion of hemophilia. Early recognition through careful bleeding history, coagulation screening, and specific factor assays is essential to prevent long-term musculoskeletal complications and unnecessary surgical procedures.

Abstract

The human respiratory system plays a vital role in gas exchange, particularly the intake of oxygen (O₂) and the removal of carbon dioxide (CO₂), which are essential for cellular metabolism. Respiratory rate is a physiological parameter that reflects pulmonary ventilation activity and varies according to the intensity of physical activity. This study aimed to analyze the effect of physical activity on respiratory rate in five participants. A simple experimental method was used, involving three activity conditions: resting (sitting), walking, and running. Respiratory rate was measured for one minute under each condition with three repetitions, and the data were analyzed descriptively. The results showed that respiratory rate increased with higher levels of physical activity: 21–28 breaths per minute at rest, 24–48 during walking, and 30–86 during running. This increase indicates a physiological response to meet the body’s elevated oxygen demand and CO₂ elimination during exertion. Therefore, respiratory rate can serve as an important indicator of physical adaptation, fitness level, and respiratory system efficiency. These findings have practical implications for health monitoring, physical education, and early detection of respiratory stress during exercise or clinical assessment.

Abstract

Organic fertilizers play a crucial role in improving soil quality and supporting sustainable agriculture in tropical regions. This study evaluates the quality of cow manure based on the solid organic fertilizer standards set by the Indonesian Ministry of Agriculture. Laboratory analyses were conducted on key chemical parameters, including organic C, C/N ratio, moisture content, macronutrients (N, P₂O₅, K₂O), and pH, accompanied by weekly composting temperature observations. The results show that the manure had a high organic C content (34.91%) and an ideal C/N ratio (17.24), indicating mature and stable compost. Moisture content (17.84%) and pH (8.17) were within the acceptable standard range, confirming good storage stability and suitability for acidic tropical soils. Nitrogen content (2.03%) met the minimum requirement, while P₂O₅ (1.26%) and K₂O (0.23%) were at moderate levels typical of cattle manure. Temperature measurements during composting showed a normal decomposition pattern, increasing from 32°C in week 1 to about 33°C in weeks 2–3 before declining in week 4, supporting the maturity of the final product. Overall, the analyzed cow manure meets the quality standards for solid organic fertilizer and has strong potential as a soil amendment and supplementary nutrient source in tropical agricultural systems.

Abstract

Diarrhea is one of the most common diseases in children and has the potential to cause various complications if not treated properly. Inappropriate treatment can trigger Drug Related Problems (DRPs) that affect the effectiveness of therapy. To identify and analyze the types of Drug Related Problems (DRPs) and recommended interventions in the treatment of diarrhea to support safe, effective, and rational drug use. A literature review was conducted by searching the PubMed and Google Scholar databases. A total of 10 articles that met the inclusion criteria were analyzed. The most common types of DRPs found were indications without therapy (7-45%), inappropriate dosing (both underdose 8-27% and overdose 7-35%), therapy without indication (10-85%), and drug interactions (12-56%). The main problems lie in the inaccuracy of clinical evaluation and irrational drug administration. DRPs in the treatment of childhood diarrhea are still common and have an impact on patient outcomes. Optimizing the role of pharmacists through medication reviews, dose adjustments, monitoring potential drug interactions, and educating health workers are key strategies for minimizing DRPs and improving treatment success.

Abstract

Sasambo Medicinal Oil is a local wisdom–based product from West Nusa Tenggara (NTB) that utilizes medicinal plants such as lemongrass, ginger, turmeric, eucalyptus, and various other ethnopharmaceutical species. In the context of phytochemistry learning, the use of this oil serves as a relevant medium for connecting the concept of secondary metabolites with the practical application of natural-product utilization. This study aims to describe the knowledge profile of students regarding Sasambo medicinal oil as a cultural heritage product that possesses significant phytochemical potential and economic value, as well as its contribution to enhancing scientific literacy. Students’ understanding of the components, benefits, and preparation processes of this traditional medicinal oil is essential to develop within chemistry education based on local wisdom. The research employed a descriptive quantitative method using closed-ended questionnaires and interviews as instruments. The research subjects consisted of 52 students from the Chemistry Education Study Program at the University of Mataram. The findings show that 73% of students have general knowledge about Sasambo oil, yet only 38% understand its chemical composition and pharmacological mechanisms. Students’ conceptual and procedural knowledge falls within the moderate category (average score of 65.2%), while the applicative aspect remains low (54.1%). These results indicate the need to strengthen scientific literacy and integrate local wisdom into applied chemistry and phytochemistry learning, thereby improving students’ conceptual understanding and awareness of the scientific and sustainable utilization of natural resources.

Abstract

The content of meat used in processed meat products such as meatballs must be verified to ensure that the food is halal. Generally, meatballs are made from beef, chicken, and fish. However, some fraudulent practices often occur in the field, which is mixing meatballs with other meats such as wild boar.  DNA-based methods can be used because they can sensitively identify the type of meat in meatballs, such as the Loop Mediated Isothermal Amplification (LAMP) method. The LAMP primers designed in this study was tested on DNA isolated from samples of meatballs containing wild boar, chicken, beef, lamb, and rat meat. Positive results were visualized using SYBR green dye, with positive results showing a color change from orange to green. The objective of this study was to design primers capable of detecting wild boar meat DNA in meatballs using simple equipment. The specific wild boar primers successfully detected wild boar meat DNA from meatballs, but the results often showed false positives. Thus, the primers designed in this study are not yet stable and applicable for use in wild boar DNA testing. The combination of the LAMP method with other methods is expected to reduce false positives from the LAMP method.

Abstract

Isosceles Triangle Plants (ITP) are wave-breaking and sediment-trapping structures with a triangular shape, arranged continuously in a zigzag pattern and made of bamboo. Mangrove rehabilitation in Sengkubang Village has been carried out independently by planting Rhizophora stylosa Griff mangrove species. This study aims to examine the physicochemical properties of soil both inside and outside the ITP structures. The study results showed that redox potential varied, with both positive and negative values. Salinity ranged from 5.228 to 5.257 mmhos/cm on the outside and from 4.971 to 5.657 mmhos/cm on the inside. Total Dissolved Solids (TDS) were between 2,754 ppm and 2,971 ppm. Organic matter content ranged from 2.754% to 2.971%. Soil acidity (pH) tended to be neutral to slightly alkaline, between 7.59 and 7.91. The soil fraction composition was dominated by silt (83.42% to 93.00%), followed by clay (6.64% to 16.24%) and sand (0.32% to 0.52%). All soil structures were massive. Soil bulk density ranged from 0.54 g/cm³ to 0.58 g/cm³. Total soil porosity was high, between 75.60% and 78.39%, as was the field capacity water content (74.36% to 77.32%).

Abstract

Lip printing (Cheiloscopy) is an effective secondary forensic identification method, based on the unique groove patterns in the lip mucosa that reflect genetic differences between ethnic groups. This descriptive cross-sectional study aimed to analyze and compare the lip print patterns of students from three main ethnic groups: Malay, Batak, and Javanese. A sample of 75 students (25 from each ethnic group) from the Biology Education Study Program, University of Jambi, was selected using a purposive sampling technique based on non-mixed criteria. Lip print analysis was performed visually and classified using the Suzuki-Tsuchihashi system which divides the patterns into six types (I, I’, II, III, IV, V). Lip print pattern Type I (Complete Vertical) was found to be the dominant pattern in all three ethnic groups, with the highest dominance in the Javanese (84.61%), followed by Malay (72%), and Batak (60%). Type V (Irregular) was not found in the sample. Contrary to previous studies, this study did not find significant variations in lip print patterns among the three ethnic groups. This Type I dominance may support the view that the three share a common ancestry or is caused by inter-ethnic interactions (gene flow) in a heterogeneous university environment. Therefore, there was no significant variation in lip print patterns between the Malay, Javanese, and Batak ethnic groups in this study population, with a consistent dominance of the Type I (complete vertical) pattern.

Abstract

The cell membrane is a semipermeable structure that regulates substance exchange between intracellular and extracellular environments, maintains cellular homeostasis, and supports metabolic processes, yet the fundamental mechanisms of diffusion, osmosis, and active transport are still frequently misunderstood in both theoretical and educational contexts. This study aims to comprehensively review substance transport mechanisms across the cell membrane and their relevance to biology education and contemporary cellular research. This research employed a narrative literature review, analyzing scientific books and peer-reviewed journal articles published within the last five to ten years, selected from databases such as Google Scholar, PubMed, and MDPI based on topic relevance. The results indicate that diffusion facilitates molecular movement along concentration gradients either directly or through transport proteins; osmosis regulates water balance through semipermeable membranes mediated by aquaporins; and active transport enables the movement of ions and molecules against concentration gradients through ATP-dependent pumps, secondary transporters, ABC transporters, and V-ATPase. These mechanisms are interconnected and influenced by membrane composition, molecular characteristics, and transporter–substrate interactions. This review highlights the importance of an integrative understanding of membrane transport processes to strengthen conceptual learning in biology education and to support advancements in cellular and biomedical research.
