Microbial Content Test on Sliced Papaya in Area of Universitas Sumatera Utara

Abstract

Papaya is a fruit that is often consumed in Indonesia and has increased consumption from 2015-2016 based on SUSENAS 2016. Papaya has high water content (85-90%) and the pH is near neutral. This makes papaya vulnerable and suitable medium for the growth of pathogenic microbes. The presence of pathogenic microbes in papaya can cause health problems for those who consumed them. Objectives this study was to observe the microbial content of sliced papaya in the Universitas Sumatera Utara. Method this research was carried out by conducting laboratory tests and the results obtained in the form of a description of microbial content in papaya cut samples. The content of coliform microbes in sliced papaya was tested using the Most Probable Number (MPN) method and biochemical identification. Papaya samples were selected using total sampling method from the University of Sumatera Utara. Results A total of 14 sliced papaya samples were analysed in this study. By using the MPN test it was found that all papaya samples had a microbial threshold exceeding those determined by SNI 7388: 2009 which is below <20 / g. A total of 9 papaya samples (64.28%) contained Klebsiella sp. bacteria, 5 samples (35.72%) contained E.coli bacteria. Conclusions Bacteria found in this study were Escherichia coli and Klebsiella sp. The presence of microbial content in the sliced papaya sample that exceeds the threshold must be a concern of various parties in the surveillance of snacks being sold.

The characterization and sensory assessment of fruit leather with a combination of puree jicama and pineapple

“…The results of the raw material analysis showed that the jicama puree had a moisture content of 80.52%, while the pineapple puree of 89.09%. The results of this study followed Lubis [9] regarding the manufacture of papaya fruit puree with pineapple puree with moisture content ranging from 13.10 to 15.47%. The more the amount of pineapple puree, the moisture content of the fruit leather produced increases.…”

“…A hundred grams of the puree mixture was poured into nonstick aluminum pans with a 6-by-6-cm surface and a thickness of 2-3 mm, and dried for about 8 hours at 60 o C in the oven. The method and base formulation developed by Kwartiningsih and Mulyanti serves as the basis for making fruit leather [9].…”

Kidney injury molecule type-1, interleukin-18, and insulin-like growth factor binding protein 7 levels in urine to predict acute kidney injury in pediatric sepsis

“…In children, sepsis caused 26%–50% of all AKI compared to 7%–10% of AKI caused by primary renal diseases ( 17 ). The incidence of AKI in septic patients admitted to the intensive care unit (ICU) ranges from 13% to 78%, depending on the severity of sepsis and the AKI criteria ( 18 ). AKI can be caused by a variety of factors, including sepsis, age, and primary disease ( 21 ).…”

“…Sepsis is a life-threatening organ dysfunction caused by dysregulation of the immune system against infection. Evidence of infection was obtained from physical examination, radiological examination, laboratory examination, and blood culture ( 18 ). Because of the high incidence of AKI due to sepsis, the difficulty in making a diagnosis, and the poor impact that arises from late diagnosis, it is essential to conduct a study to determine the role of urinary KIM-1, IL-18, and IGFBP-7 biomarkers in predicting the AKI occurrence in children with sepsis.…”

Valorization of durian peel waste and sewage sludge as bio-briquette

“…The 90% sewage sludge and 10% rejected papaya binder reached a moisture content of 31%. The high-water content of papaya, approximately 85-90% [31], affected the moisture content of the final product of briquettes.…”
