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.

Abstract

Anura are amphibians capable of living in both terrestrial and aquatic habitats, yet they are highly sensitive to environmental changes. Some Anura species can adapt well, while others are more vulnerable to such changes. The Lau Timah River, located in Desa Bukum, Sibolangit, North Sumatra, is known for its high diversity of Anura species, supported by abundant water availability. This study aimed to identify Anura species and analyze their morphometric variations in the Lau Timah River. The research employed the Visual Encounter Survey (VES) method with three repetitions on different days. A total of 24 individuals were sampled, and 13 Anura species were identified, including Chalcorana chalconota, C. kampenii, C. rufipes, Odorrana hosii, Pulchrana siberu, Huia sumatrana, Limnonectes blythii, L. kuhlii, L. macrodon, Pelophryne signata, Letophryne borbonica, Ingeophrynus divergens, and Megophrys nasuta. The species were documented and measured for morphometric analysis. The analysis revealed significant morphometric differences in parameters such as PB, PM, LK, PK, PMTJ4, and PTJ4. The highest R² values were found in L. kuhlii, L. macrodon, I. divergens, and L. borbonica, indicating a very strong correlation.

Abstract

Local wisdom represents traditional knowledge passed down through generations and plays a strategic role in the conservation of medicinal plants and the environment. North Sumatra, with its cultural diversity and rich local wisdom, holds significant potential to support environmental conservation. This study aims to explore the role of local wisdom in preserving medicinal plants and the environment through cultural, ecological, and social approaches. The method employed is a descriptive-analytical approach based on literature reviews and case studies from various regions in Indonesia. Several local wisdom practices, such as lubuk larangan, hutan larangan, and the subak system, demonstrate the success of sustainable environmental management. However, challenges such as modernization and globalization threaten cultural values and lead to the homogenization of traditions. Strategies like digitizing local wisdom, integrating it with modern knowledge, and strengthening protective policies are essential to ensure the sustainability of culture and ecosystems. This study emphasizes the importance of harmonizing traditions with contemporary dynamics to achieve more effective conservation efforts.

Abstract

Aspirin is one of the most commonly used nonsteroidal anti-inflammatory drugs (NSAIDs); however, long-term use and high doses can damage liver function and structure. To reduce aspirin’s side effects, kenikir leaves (Cosmos caudatus K.) are used as an alternative treatment. This study aims to evaluate the effects of kenikir leaf extract on liver damage caused by aspirin, both morphologically and histopathologically. A total of 25 male white rats were divided into 5 groups: KN (control), KP (aspirin 200 mg/kg BW for 10 days), P1 (aspirin + kenikir extract 700 mg/kg BW for 14 days), P2 (aspirin + kenikir extract 800 mg/kg BW for 14 days), and P3 (aspirin + kenikir extract 900 mg/kg BW for 14 days). Liver cell damage was analyzed using scoring and histomorphometry methods, followed by one-way ANOVA and Duncan’s test. The results showed that kenikir leaf extract significantly improved the morphology and histopathology of rat livers induced by aspirin, including parenchymal degeneration, hydropic degeneration, and necrosis. The most effective dose was 800 mg/kg BW, which also improved the diameter of the central vein and the width of the liver sinusoids.

Abstract

This study aims to investigate the relationship between gender and allergy scores in children aged 0-12 years with allergic rhinitis and atopic dermatitis. The research utilized secondary data obtained from patient medical records, comprising 32 samples with 18 males and 14 females. Data were analyzed using the non-parametric Mann-Whitney U test to evaluate the relationship between two variables: gender (binomial data) and allergy score (ordinal, interval, or ratio scale). Results indicated that U₁ was 112 and U₂ was 140. According to the Mann-Whitney critical value table with n₁=14 and U₂=18 at a 95% confidence level, the critical value was 74. Since the lowest U value (U₁ = 112) is greater than the critical value (74), H₁ is accepted and H₀ is rejected. Therefore, there is a relationship between gender and allergy scores in children aged 0-12 years with allergic rhinitis and atopic dermatitis at RSIA Stella Maris, Medan. However, the statistical analysis suggests that this relationship is weak.

Abstract

Escherichia coli is most common nosocomial pathogenic bacteria recognized as the highest cause of ESBL production. Derivatives of CTX-M, especially type CTX-M-15 (blaCTX-M-15) as the dominant ESBL-encoding gene found among E. coli isolates. The most important component in PCR is primer. Primer design can be done by in silico bioinformatics analysis. This study was conducted to produce a primer sequence of E. coli CTX-M-15 gene as a candidate biomarker for E. coli ESBL detection. The method used was in sillico observational using the Primer3Plus application and in silico PCR on candidate primers for the E. coli CTX-M-15 gene. Primers were selected based on criteria including%GC, primer length, Tm (melting temperature), stability, and primer interactions (the presence of dimers and hairpins). The sample used was the nucleotide sequence of the E. coli CTX-M-15 gene strain K-20 plasmid Genbank: GQ330540.1. The results showed that 2 pairs of forward and reverse primer pairs (pairs 1 and pairs 5) were able to amplify the blaCTX-M-15 gene sequence measuring 525bp and 519bp. In silico PCR analysis resulted in 2 pairs of new primer pairs being successfully designed and potentially used as DNA biomarkers from Escherichia coli in early and rapid detection of ESBL infection.
