Abstract

Dysmenorrhea is severe pain in the lower abdomen during menstruation. Dysmenorrhea is one of the health problems that has a high incidence rate worldwide. The purpose of this study was to determine the relationship between anemia, stress levels, physical activity and fast food consumption with the incidence of primary dysmenorrhea in SMA IT Putri Abu Hurairah Mataram. This research is an observational analytic quantitative research with a cross-sectional study design. The population of this study were all 374 students of SMA IT Putri Abu Hurairah Mataram. The research instruments used were questionnaires in the form of WaLLID score questionnaire, DASS questionnaire, International physical activity questionnaire short form (IFAQ-SF), and Food Frequency Questionnaire (FFQ). Data were analyzed using Spearman, univariate, and bivariate tests. The results showed that (1) there was no significant relationship between anemia and primary dysmenorrhea; (2) there was a significant relationship between stress level and primary dysmenorrhea; (3) there was a significant relationship between physical activity and primary dysmenorrhea; (4) there was a significant relationship between fast food consumption and primary dysmenorrhea.

Abstract

Usually, dragon fruit is only used for the flesh while the skin is discarded and considered waste. Dragon fruit peel contains vitamin C, vitamin E, vitamin A, alkaloids, terpenoids, flavonoids, thiamine niacin, pyridoxine, cobalamin, phenolics, carotene and phytoalbumin. 30-35% of dragon fruit is the skin of the fruit but it is often just thrown away as trash. Dragon fruit skin contains quite a lot of the natural dye anthocyanin. This research aims to determine the effect of pH, water content, vitamin C, and organoleptics on the of dragon fruit skin boba using the basic spherificatiom technique. This research used laboratory experimental methods using a completely randomized design (CRD) with varying concentrations of sodium alginate (1gr,1,1gr,1,2gr,1,3gr, dan 1,4gr) calcium lactate (5 grams) for each treatment. This was repeated 3 times, the analyzes tested in this study were pH, viscosity and organoleptic tests. The parametric data obtained were analyzed using analysis of variance (ANOVA) using statistical product and service solution (SPSS) version 23 data and for non-parametric data using Kruskal Wallis.

Abstract

Kombucha is a health drink that has good benefits for the body, contains polyphenols and is antioxidant so it is said to be a functional drink. Chamomile positively contains flavonoid compounds, polyphenols, and tannins as antioxidants to ward off free radicals. The purpose of this study was to determine the effect of fermentation duration and concentration of chamomile flowers (Matricaria recutita) to produce kombucha drink with the best physicochemical and organoleptic quality. This study used a one-factorial Completely Randomized Design consisting of four treatments of a combination of fermentation duration (5 days and 7 days) and chamomile concentration (0.5% and 1%), each treatment was carried out three times. Parameters analyzed included color (L*a*b*), pH, antioxidant activity and organoleptic (taste, color, and aroma). The results showed that the length of fermentation and chamomile concentration had a significant effect on color (L*a*b*), pH, antioxidant activity and organoleptic parameters (taste and color). On organoleptic parameters (aroma) did not have a significant effect. The best treatment with antioxidant activity value of 67.09% in treatment F2C2 (7 days fermentation time and 1% chamomile concentration). The highest organoleptic quality was in the F1C1 treatment (5 days fermentation and 0,5% chamomile concentration).

Abstract

Diarrhea is one of the diseases caused by symptoms of intestinal tract infections due to various microorganisms. Goosegrass (Eleusine indica (L.) Gaertn) is a wild weed that has long been used as a traditional medicine, attributed to its phytochemical compounds such as tannins, alkaloids, flavonoids. This study aims to evaluate the antidiarrheal effects of Eleusine indica extract by comparing six treatment groups: a healthy group, a negative control group (Na-CMC), a positive control group (Loperamide 2 mg), and three variations of the extract dosage. Observations were made over 360 minutes at 30-minute intervals, using a fecal consistency scale from 1 (solid) to 5 (liquid). LC-MS/QToF analysis identified 25 secondary metabolites in the extract, including flavonoids (Schaftoside, Orientin, Vitexin, Tricin), phenolic compounds, and terpenoids. In vivo testing showed that the third dose of Eleusine indica grass extract had the most optimal antidiarrheal effect among the three doses, as evidenced by its ability to reduce diarrhea frequency, decrease fecal weight, shorten diarrhea duration, and improve fecal consistency, approaching the effectiveness of Loperamide 2 mg as a positive control. These findings suggest the potential of Eleusine indica extract as a promising natural antidiarrheal agent.

Abstract

Indonesia is one of the countries with the highest biodiversity in the world. However, this high diversity requires individual awareness and responsibility to maintain and utilize it sustainably. Therefore, biodiversity literacy is an important element, especially for students as prospective future generations who will play a role in natural resource management in the future. This study aims to evaluate the level of biodiversity literacy of students of the Biology study program at the University of Education Mandalika, by assessing six dimensions of biodiversity literacy: Conservation and Importance of Biodiversity (CIB), Ethics and Biodiversity (EB), Sustainability and Biodiversity (SB), Taking Action to Protect Biodiversity (TAPB), Biodiversity and Utility (BU), and Conservation and Importance of Species (CIS).  The method used was quantitative descriptive, involving 50 students as respondents. The instrument used consisted of 27 items that were analyzed using One Way ANOVA to determine the average score and significant differences based on gender and student scores. The results showed that the average score of biodiversity literacy obtained a score of 2.08 with a less significant category (Low Biodiversity Literacy). Most of the indicators are at an average value below 2.50, only a small number of indicators have an average value above 2.50. In the CIB dimension, only 3 indicators have an average value of > 2.50 out of 5 indicators. In the TAPB dimension, only 1 indicator has an average > 2.50. While in other dimensions, the average value < 2.50. In addition, there was no significant difference in student scores based on gender. Thus, student biodiversity literacy still needs to be improved, especially in the aspects of real action and individual responsibility.
