BACKGROUND: The access to safe drinkingwater is increasingly difficult, especially in water catchment or coastal areas.Due to the difficulty, people in coastal areas tend to consume ready-to-use refilled drinking-water.However, the sanitation facilities on most drinking-water refill THE EFFECTS OF PANDEMIC DISEASES ON THE WORLD ECONOMY depots do not meet the requirements, hence really prone to microbial contamination.

We conducted this study to determine the types of bacteria causing the contamination of refilled drinking-water from refill depots in Abeli, a coastal area in Kendari.METHODS: Samples were collected from all 6 drinkingwater refill depots in Abeli.Three-series fermentation tubes were used for the microbiological test, including the presumptive, confirmative and completed tests.

The biochemical test was performed with indole test, methyl red test, Voges-Proskauer test, and citrate utilization test (IMViC) methods and the triple sugar iron agar (TSIA) test.RESULTS: Implementation of Data Mining Prediction Delivery Time Using Linear Regression Algorithm Among 6 refilled drinking-water samples, we found the growth of coliform bacterial colonies in 3 samples, exhibiting various characteristics.Based on the characteristics, both microbiological and biochemical, the identified bacteria were Proteus sp.

, Escherichia coli and Klebsiella oxytoca.CONCLUSION: Bacteria that contaminated refilled drinking-water in Abeli were Proteus sp., E.

coli and K.oxytoca.Continuous supervision is required to ensure the quality of water from drinking-water refill depots.
