Abstract

Myrmecodia sp., also known as ant plant, has therapeutic potential such as anticancer, antioxidant, anti-inflammatory, and other metabolic syndrome therapies, but there are still few publications on it. Candida albicans and Staphylococcus aureus are normal flora in the digestive and vaginal tracts, but under certain conditions, they can cause infections if their growth becomes excessive and is in an inappropriate location. Conversely, although Fusarium sp. is not part of the normal flora, these three microflora can be triggering factors for pelvic inflammatory disease infections in other organisms. The study aims to determine the sensitivity comparison of Candida albicans, Staphylococcus aureus, and Fusarium sp. to Myrmecodia sp., Jack in vitro. The research results obtained a significance value of 0.0000.05, where the most effective concentrations were Candida albicans at 3.2%, Staphylococcus aureus at 1.6%, and Fusarium sp. at 0.8% as triggering factors for pelvic inflammatory disease infections. The data show that Myrmecodia sp. extract effectively suppresses pelvic inflammatory disease infections caused by Candida albicans, Staphylococcus aureus, and Fusarium sp, with Fusarium sp. being declared to have a stronger sensitivity to Myrmecodia sp. extract.

Abstract

Endophytic bacteria are bacteria that live within plant tissues and are capable of producing secondary metabolites in the form of bioactive compounds similar to those produced by their host plants. This study aims to isolate and characterize endophytic bacteria from the roots of kecombrang (Etlingera elatior (Jack) R. M. Smith) and to test their ability to inhibit the growth of Staphylococcus aureus. The research was conducted using a quantitative descriptive method through several stages, including sample preparation, sterilization of equipment and media, isolation, characterization, and testing. The results identified three isolates of endophytic bacteria from the roots of kecombrang, namely AK1, AK2, and AK3, which were shown to be gram-positive cocci. Inhibition tests indicated that these endophytic bacteria exhibit antagonistic properties against Staphylococcus aureus. The isolate coded AK1 had an inhibition zone of 9.6 mm, AK2 had the lowest inhibition zone of 6.6 mm, and AK3 had the largest inhibition zone of 13.5 mm.

Abstract

Liquid organic fertilizer (LOF) is utilized as an alternative to enhance soil quality and crop yields. Organic waste from watermelon rinds (Citrullus lanatus) serves as one of the raw materials for LOF production. This study aims to assess the impact of LOF on the growth of curly lettuce (Lactuca sativa). The research employed an experimental method with five different LOF concentrations, ranging from no LOF (control) to 10% LOF. The results indicate that LOF application does not significantly affect the height of the plants, leaf count, leaf width, or the wet weight of curly lettuce. However, the use of undiluted 100 ml LOF leads to wilting and plant death, while increasing LOF concentration does not support the optimal growth of curly lettuce.

Abstract

Blood glucose level represents the amount of sugar circulating in the bloodstream, originating from the breakdown of carbohydrates consumed in food and stored in the form of glycogen in the liver and skeletal muscles. Factors influencing blood glucose levels include dietary patterns, lifestyle, changes in body weight, age, and level of physical activity. Body Mass Index (BMI) is used to assess an individual's nutritional status by comparing their weight and height. This research was conducted to investigate the correlation between blood glucose levels and BMI among adolescents at the Adolescent Integrated Health Service Post in Jati Utomo Sub-District, Binjai City. Involving 30 adolescents, this study employed tests of normality and Spearman correlation analysis to analyze the data. The research findings indicate a strong correlation between BMI and blood glucose levels, with a correlation coefficient (r) of 0.67. This suggests that higher BMI correlates with higher blood glucose levels, providing valuable insights into the relationship between BMI and metabolic health in adolescents.

Abstract

Phosphorus is a very important nutrient for plants. However, most of the phosphorus is bound by soil colloids and is insoluble, so the role of phosphate solubilizing bacteria is needed to release the bound phosphate. This study aims to isolate, characterize, and test the pathogenicity of phosphate solubilizing bacterial isolates. This research used an exploratory method including taking soil samples, bacterial isolation, calculating the density of bacterial colonies, calculating the phosphate solubility index value and selecting potential bacteria, morphological and physiological characterization, and pathogenicity test. The results showed that the colony density was 3,2 x 103 CFU/g with phosphate solubility index values ranging from 1,38-3,65. The colony with the highest phosphate solubility index value is JE1 with a value of 3,65; JE2 with a value of 3,63; JE3 with a value of 3,13; JE4 with a value of 3,08; and JE5 with a value of 2,94. Colonies have an irregular shape with undulate edges, the colony color is predominantly white with umbonate, raised and flat elevations. Most isolates have short bacillus cells that are Gram negative, do not form spores, are able to ferment glucose, produce the enzyme catalase, and are not motile. The pathogenicity test showed that only the JE1 isolate was not pathogenic to tobacco leaves.

Abstract

Anthracnose and crown rot caused by Colletotrichum sp and Phytopthora sp fungi are one of the main problems in guava and pineapple cultivation. This research aims to determine the growth of Trichoderma isolates (T14 and T7834), the potential of the isolates as biocontrol agents and the activity of lipase and chitinase enzymes. Research data was analyzed descriptively qualitatively. This study concluded that the growth graph of Trichoderma isolates began with an increase in mycelium dry weight on day 3, on day 12 the dry weight of mycelium increased rapidly, on day 21 the dry weight of mycelium was constant, on day 30 the dry weight of mycelium decreased. The results of the Trichoderma compatibility test were able to inhibit the growth of the fungus Phtyopthora sp. and Colletotrichum sp. so it is effective as a biocontrol agent to control the pathogenic fungus Phytoptora sp. and Colletotrichum sp. in vitro. However, Trichoderma T7834 is unable to inhibit the growth of the Colletotrichum fungus, so it is less effective as a biocontrol agent. The results of the enzyme activity test showed that Trichoderma was only able to produce the lipase enzyme, so the two isolates had the potential to be candidates for biocontrol fungi.

Abstract

The fruit of the berry (Crescentia cujete) had been widely known by the community. However, the use of this fruit had not been widely explored, especially related to the morphology and anatomy of the fruit, which supported its potential as a sustainable basic material. This study aimed to study the morphology and anatomy of berenuk fruit and explore its use as a basic material for crafts and household tools. The method used was qualitative descriptive, and the sampling technique was purposive sampling. Data was collected through field surveys, interviews with local artisans, and direct observation of the processing and utilization process of berenuk fruits. The data was reinforced through literature studies. The results of the study showed that Berenuk Fruit had great potential in diversifying the local economy, creating business opportunities, and supporting environmental conservation. The morphology and anatomy of the berenuk fruit, such as its hard skin and wide inner cavity, strongly supported the use of this fruit as a raw material for crafts and household tools. Furthermore, it was very necessary to increase people's knowledge and skills regarding processing techniques to maximize the use of berenuk fruit, as well as a good marketing strategy so that this fruit-based product could compete in a wider market.
