Relationship Between Allergy and Chronic Rhinosinusitis
Get PDFThe role of allergy in chronic rhinosinusitis is still controversial. Numerous studies have demonstrated that atopy is highly prevalent in people with chronic rhinosinusitis (CRS), and that allergies may play a part in the pathogenesis of the condition. Allergy disorders, particularly those involving IgE-mediated in/flammation, are generally considered as triggering factors in the development of chronic rhinosinusitis or comorbidities/associated factors for the spread of chronic rhinosinusitis. The study aimed to determine the relationship between allergies and chronic rhinosinusitis. Observational analytical study with cross-sectional approach. 30 patients with symptoms of runny/blocked nose were examined. Allergy test, namely skin prick test, has been examined to categorize allergic and non-allergic patients. Total serum IgE and total eosinophil examination from blood were then categorized as increased and normal. The criteria for chronic rhinosinusitis are complaints of runny/blocked nose and facial pain and/or decreased sense of smell. Thirty patients (19 females and 11 males) aged 17 to 77 years were examined in this study. 19 patients were confirmed to have rhinosinusitis and 11 had rhinitis. The results of the analysis using the Chi Square test showed that there was no significant relationship between allergy, IgE, eosinophils, and chronic rhinosinusitis (p>0.05). There was no significant relationship between allergy, IgE, eosinophils with chronic rhinosinusitis
Effect of Different Nitrogen Concentrations on the Growth Rate of Caulerpa lentillifera Sea Grapes
Get PDFCaulerpa lentillifera is a strategic macroalgae commodity in controlled cultivation that requires nutrient management optimization for maximum productivity. This study evaluated the effect of nitrogen concentration variations (0, 15, 30, 45 ppm) on algae growth parameters in a complete randomized design with three replicates over 15 days (12 experimental units). Data analysis was carried out using One-Way ANOVA (95% confidence level) and Duncan post-hoc test to compare parameters such as absolute and relative biomass, specific growth rate, rate of decline, biomass residue, and chlorophyll-a content. The results showed that the concentration of 45 ppm resulted in the highest absolute biomass (23 g) and optimal relative growth (36.59%), while 30 ppm provided the highest specific growth rate (7.40 %/day) and the lowest specific decline rate (2.3 %/day). Surprisingly, the control (0 ppm) recorded the highest chlorophyll-a (20 μg/g), while at 45 ppm there was a significant decrease (9.67 μg/g). It is concluded that the optimal nitrogen range is 15–30 ppm, as it offers the best balance between productivity and physiological stability. At the applicative level, it is recommended the use of moderate nitrogen concentrations in commercial cultivation of C. lentillifera for economic efficiency without sacrificing biomass quality
Hydrothermal Synthesis of Carbon Dots Derived from Biomass: A Simple and Sustainable Approach
Get PDFCarbon dots (CDs) are a class of carbon-based nanomaterials that have attracted significant attention in the field of nanotechnology due to their strong photoluminescence, biocompatibility, and ease of surface passivation. In recent years, biomass-derived approaches for CDs synthesis have become a primary focus, driven by the growing demand for environmentally friendly, cost-effective, and sustainable synthetic methods. This study aims to synthesize carbon dots (CDs) from molasses, a sugar-based biomass waste, using a simple hydrothermal method. Characterization results revealed that the synthesized CDs have an average particle size of 313.5 nm and retain surface functional groups such as –OH, –COOH, C=O, and C–H, which are essential for extended applications. The findings demonstrate that molasses can serve as a viable carbon source that not only supports the concept of green synthesis but also opens new opportunities for biomass-based CDs in sustainable applications, including environmental remediation, adsorbents, or macro-scale drug delivery systems suitable for mucosal or gastrointestinal routes. Moreover, this work contributes to the advancement of eco-friendly carbon-based materials

Effect of Solvent Amount and Sugar on Chemical Traits of Instant (Curcuma xanthorrhiza Roxb.)
Get PDFTemulawak, also known as Curcuma xanthorrhiza Roxb., is a long-used medicinal plant that is frequently utilized as an ingredient in traditional medicine. At harvest, the ginger rhizome has 80–90% water content. When ginger is harvested with a high water content, its quality declines and its selling price drops. The purpose of this study is to ascertain how variations in the concentrations of sugar and water affect the color and chemical characteristics of temulawak powder. Water content, flavonoid and tannin levels, and antioxidant activity were all tested as part of the analysis. The data was statistically calculated using the Complete Randomized Block Design, and analysis of variance (ANOVA) was carried out at a 95% confidence level. whether the actual differences in each therapy were shown by the Duncan Multiple Range Test (DMRT). The findings demonstrated that the water content, flavonoid levels, tannin levels, and antioxidant activity are all significantly impacted by the amount of water and the addition of sugar. When 100 ml of water and 100 g of sugar are mixed together, the temulawak powder's water content is 3.01%, its flavonoid content is 1.73 mg GAE/g bk, its tannin content is 10.99 mg/100g, and its antioxidant activity is 83.30% RSA
Influence of Vespa sp. Wasp Disturbance on Foraging Activities and Apis cerana Populations in the Greater Forest Park Area Ir. H. Juanda
Get PDFHoney bees (Apis spp.) play a crucial role in maintaining ecosystem balance through pollination, which directly impacts the sustainability of biodiversity and human food security. Studies on the antagonistic interactions between Apis cerana and Vespa sp. are still relatively limited in Indonesia, particularly in conservation areas such as Tahura Djuanda. This study aims to observe the disruptive factors of Vespa sp. wasps, a natural enemy of the Apis cerana honey bee in Tahura Djuanda. The methods used were direct field observation and recording of Vespa sp. activity on bee colonies. The seven-day study showed that disruption by Vespa sp. wasps on the foraging activity of Apis cerana bees occurred with high frequency. The average number of Vespa sp. presence per day in insect tubes installed in calliandra flowers reached 23,28 individuals, significantly higher than the control of 3,43 individuals per day. This disturbance caused a significant decrease in bee foraging activity, increased defensive behavior, and the potential for colonies to abandon the nest (absconding). This study confirms that Vespa sp. is a natural enemy that can reduce the activity and productivity of Apis cerana colonies, and that control strategies are needed to minimize its impact

Effectiveness testing used a one-group pretest-posttest design and included 36 students from Classes XI IPA 2 and 3 at the same school. Data collection instruments included validation sheets, teacher and student response questionnaires, lesson implementation observation sheets, and SPS questionnaires. Data were analyzed using Aiken’s V index, percentage calculations, and the N-Gain test. The validation results showed that both the module and instruments had average validity ratings categorized as "highly valid" (Aiken's V > 0.80). In terms of practicality, student responses averaged 96.39%, teacher responses averaged 92.95%, and the implementation of the three learning sessions averaged 88.88%. Effectiveness results indicated that the module was moderately effective in improving science process skills, with an N-Gain score of 0.65 (medium category) and an effectiveness rate of 65.71%. It can thus be concluded that the Problem-Based Physics Teaching Module is valid, practical, and moderately effective in enhancing students’ science process skills
The Effect of PjBL on Critical Thinking Skills of High School Students in Physics Learning on Topic of Static Fluid
Get PDFIn the 21st century, students are required to possess a variety of skills to face the challenges of the times, one of which is critical thinking. Educational activities, including physics instruction, serve as an important medium for fostering these skills. However, physics is often perceived as a challenging subject, primarily due to the dominance of teacher-centered learning models. This highlights the need for student-centered approaches that actively engage learners in the educational process. One such approach is the Project-Based Learning (PjBL) model. This study aims to examine the effect of the PjBL model on students' critical thinking skills in physics learning, specifically on the topic of static fluids. The hypotheses tested in this study are: H₀ (there is no significant effect of the PjBL model on students’ critical thinking skills) and Hₐ (the PjBL model has a significant effect on students’ critical thinking skills). The research employs a quasi-experimental design with a control group. The population consists of Grade XI students at SMA IT Abu Hurairah Putri, Mataram City. A saturated sampling technique was used, with class XI MIPA 1 assigned as the experimental group and XI MIPA 2 as the control group. The research instrument was a critical thinking test comprising four questions, all of which were previously validated and proven reliable. Data analysis was conducted using the Mann-Whitney U test at a 5% significance level. The results indicate a p-value of 0.001, which is less than the threshold of 0.05. Thus, the null hypothesis (H₀) is rejected, leading to the conclusion that the PjBL model has a significant effect on students' critical thinking skills
Analysis of the Effectiveness of Turmeric Flour Supplementation on Quail in the Grower Phase
Get PDFTurmeric (Curcuma domestica Val) contains curcumin, which enhances immunity and aids digestion in livestock. This study aimed to evaluate the effect of turmeric flour supplementation in quail rations on their growth performance. A total of 100 female grower quails (Coturnix-coturnix japonica), aged 3 weeks, were used in a completely randomized design (CRD) with four treatments and five replicates, resulting in 20 experimental units. The treatments included P0 (control, 0% turmeric flour), P1 (0.05% turmeric flour), P2 (0.1% turmeric flour), and P3 (0.15% turmeric flour). The study lasted 14 days, from 21 to 34 days of age. Observed variables included body weight gain, feed intake, and feed conversion ratio (FCR). Results indicated that turmeric flour supplementation at 0.05%–0.15% had no significant effect on quail performance. It is concluded that turmeric flour supplementation up to 0.15% does not enhance quail growth. Further studies are recommended to investigate its effects over a longer period or different growth phases
