Abstract

Thai tea is one of the drinks that are popular with urban people. However, the less hygienic processing and presentation process can be a source of microbiological contamination. This study aims to detect the presence of Escherichia coli in Thai tea drinks sold on Jalan Ayahanda, Medan, using the Most Probable Number (MPN) method. The research design was quantitative descriptive with a laboratory experimental approach, using ten samples from Thai tea sellers. The results showed that all samples were positive for coliform with an MPN value of 15 – 460 MPN/100 mL, eight samples were positive for the BGLB confirmatory test, and one sample (10%) was positive for E. coli in EMB media. Based on the SNI standard (0/100 mL), the positive sample was declared unfit for consumption. These findings confirm the importance of implementing good hygiene and sanitation in the processing and sale of beverages to ensure food safety.

Abstract

Masalah resistensi antibiotik yang semakin meningkat, terutama pada infeksi nosokomial, telah menjadi masalah kesehatan global yang signifikan. Acinetobacter baumannii dan Klebsiella pneumoniae termasuk di antara patogen paling berbahaya yang berkontribusi pada resistensi ini, sehingga infeksi yang disebabkan oleh bakteri ini sulit diobati. Penelitian ini menyelidiki ekstrak etanol Ashitaba (Angelica keiskei), tanaman obat yang dikenal memiliki sifat antioksidan, antiinflamasi, dan antibakteri, sebagai agen antibakteri alternatif potensial. Penelitian ini bertujuan untuk mengevaluasi efektivitas antibakteri ekstrak etanol Ashitaba terhadap patogen resisten seperti Acinetobacter baumannii dan Klebsiella pneumoniae. Potensi antibakteri diuji menggunakan metode difusi cakram (Kirby–Bauer) untuk mengukur diameter zona hambat pertumbuhan Acinetobacter baumannii dan Klebsiella pneumoniae pada berbagai konsentrasi ekstrak. Hasil penelitian ini diharapkan dapat memberikan wawasan berharga tentang potensi Ashitaba sebagai sumber alami agen antibakteri, menawarkan alternatif bagi antibiotik konvensional dalam mengobati infeksi bakteri resisten.
