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.

Abstract

Traditional snack cakes can be contaminated with harmful microbes due to poor hygiene and sanitation practices. This study aims to identify the types of bacteria contaminating traditional snacks sold by street vendors on Jl. Al-Falah. The method used is the pour plate technique on Plate Count Agar for 24 hours at a temperature of 33-35 °C, along with selective media Salmonella Shigella Agar and Eosin Methylene Blue Agar. Observations include both fresh samples and those stored for 24 hours. Confirmation tests were conducted on SSA and EMBA media, followed by SCA (Simmon Citrate Agar). The results showed that six types of cakes exceeded the microbial contamination limits: P1S1 (6.2 × 10⁵ colonies/g), P2S1 (10 × 10⁴ colonies/g), P3S1 (4.8 × 10⁴ colonies/g), P1S5 (5.6 × 10⁴ colonies/g), P2S5 (5 × 10⁴ colonies/g), and P3S5 (8.6 × 10⁴ colonies/g). Out of 15 samples, two were detected to contain pathogenic bacteria: P1S1 was positive for Salmonella sp. and Escherichia coli, while P3S2 was positive for Escherichia coli. In conclusion, the contaminating bacteria Salmonella sp. and Escherichia coli were found in cake samples from different vendors.

Abstract

Air pollution is still an environmental problem that has not been resolved until now. There are several alternative methods that can be applied to monitor air quality levels, one of which is using bioindicators. Lichens can be used as bioindicators because they are accumulators and are very adaptive to changes in environmental conditions. This study aims to assess the effectiveness of Crustose sp. (Cryptochemua) and Foliose sp. (Parmelia) lichens as bioindicators of air pollution levels. This study used a systematic review method. Literature was selected based on 3 criteria: relevant to the topic, journal articles within 5 years, and from SCOPUS or SINTA accredited journals. After the selection process, 6 articles were selected for review based on the specified criteria. The results showed that to identify Crustose sp. (Cryptochemua) and Foliose sp. (Parmelia) lichens as bioindicators of air pollution, it is not enough to only consider the number of lichens or morphology found. However, it is also necessary to identify the affected lichen species, biotic and abiotic factors in order to obtain effective and valid results. For future researchers, it is recommended to compare the efficiency of Crustose sp. and Foliose sp. lichen plants as bioindicators of air pollution with other plants.

Abstract

Successful embryo culture is influenced by culture methods and conditions, which have an impact on cytoplasmic factors and the ability of embryo development. This study aims to compare the effectiveness of two culture mediums, M16 and CZB, in supporting the development of DDY strain mice embryos in vitro. The research method used was an experimental study consisting of animal husbandry, medium culture preparation, superovulation, collection, and in vitro embryo culture. Data analysis in this study used descriptive statistical tests to measure embryo development in each culture medium, M16 and CZB, in observations for 96 hours with a 24-hour interval using an inverted microscope. The results showed that embryos in the CZB medium experienced 50% development of the expanded blastocyte stage after 96 hours of culture with 50% degenerative. In the M16 culture medium, 0% of embryos experienced embryonic stage development after 96 hours of culture and 100% were degenerative. This study has concluded that the development of embryos in vitro in the M16 culture medium was not better than CZB, this was evidenced by the percentage at the expanded blastocyte development stage.

Abstract

Microbial contamination in vegetables often originates from spraying or irrigation with contaminated water. Fertilization using animal manure can also lead to contamination, with bacteria such as Salmonella and E. coli found in vegetables like lettuce. Samples were collected once from each traditional market, repeatedly taken from roadside stalls, inside the market, or from kiosks. Macroscopic colony characteristics on EMBA (Eosin Methylene Blue Agar) and SSA (Salmonella-Shigella Agar) media were observed after incubation, including colony shape, color, structure, and growth size or diameter. EMBA media cultures of E. coli on five vegetable samples from Pasar Melati, Pasar Sei Sikambing, and Pasar Kampung Lalang showed contamination in all five samples. SSA media cultures of Salmonella sp. on five vegetable samples from these markets revealed contamination in one sample. Gram staining of all samples identified Gram-negative bacteria, appearing red in color.
