Abstract

Background: Caulerpa lentillifera is a species of green algae that has been cultivated widely in Indonesia for its nutritional contents and health benefit. This seaweed builds a strong association with bacterial community which play an important role in synthesizing various secondary metabolites including antibacterial activity. Aims:The research aim to explore the symbiotic relationship between C. lentillifera and its associated bacterial community, focusing on the potential of these bacteria to produce antibacterial metabolites.Methods:Bacterial cultivation was performed on three different media namely nutrient agar, plate count agar, and zobell marine agar. The obtained bacterial isolates were identified morphologically and subsequently were screened for their antibacterial activity based on perpendicular cross streak method against Staphylococcus aureus ATCC 25923, Streptococcus mutans FNCC 0405, Escherichia coli ATCC 25922, and Klebsiella pneumoniae ATCC 700603. Results: 20 out of 28 bacterial isolates inhibited against at least one of the bacterial targets. Bacterial isolate encoded as NAR9 showed as the most promising bacterial isolates with length inhibition of 19 mm against S. mutans FNCC 0405. Amplification of 16S rRNA gene fragment of the NAR9 bacterial isolate followed by Sanger sequencing showed that the isolate NAR9 has been phylogenetically related to Marinobacter hydrocarbonoclasticus. Conclusion: Overall, this research provides a preliminary result of the untapped potential of bacteria associated with C. lentillifera as the source of antibacterial activity.

Abstract

Highlights: • Eschericia colli was the most contaminant bacteria among food samples from Warmadewa Cafeterias • Further suggestions to increase the hygiene in food processing must be offered. Abstract : Foodborne diseases still remain a problem especially in public areas. This study aimed to identify pathogenic bacteria in foods sold at the cafeterias of Universitas Warmadewa, Denpasar, Indonesia. The presence of pathogenic bacteria in the food samples was identified using the brain heart infusion (BHI) agar for the growth of Escherichia coli and Streptococcus aureus, selenite for Shigella and Salmonella, and alkaline peptone for Vibrio cholerae, then bacterial culture was conducted to identify the species. The results showed that Escherichia coli were found in two food samples, kangkong and jinggo rice, with the colony counts of 50-118. Escherichia coli was the most commonly found contaminant in food samples from the Warmadewa Cafeterias. Further suggestions must be offered to increase hygiene in the food processing by advising the stalls' owners to serve good foods and conducting regular inspections to assess the food quality.

Abstract

Makanan dan minuman merupakan sumber energi bagi manusia dalam kehidupan sehari-hari. Pemilihan makan dan minuman yang tidak cermat mengakibatkan konsumen mengonsumsi makanan dan minuman yang terkontaminasi yang dapat menimbulkan penyakit. Penyakit yang ditimbulkan melalui makanan dan minuman yang terkontaminasi disebut dengan Foodhandler diseases. Penelitian ini bertujuan untuk mengidentifikasi bakteri Klebsiella sp dan Citrobacter sp pada Makanan dan Minuman di Beberapa Pasar Tradisional. Metode Penelitian ini menggunakan rancangan deskriptif eksplorasi. Pemilihan sampel dilakukan secara acak di Pasar tradisional di wilayah Denpasar. Setiap pasar dilakukan pengambilan sampel makanan dan minuman dilakukan secara random terdiri dari 5 sampel pada masing-masing pasar yang berasal dari 7 pasar tradisional di Denpasar. Pada penelitian ini sampel makanan dan minuman diisolasi menggunakan media selective Mac Conkey dan identifikasi menggunakan uji biokimia dengan Imvic Test.Hasil ppenelitian menunjukkan pada makanan dan minuman dari 7 pasar didapatkan terkontaminasi bakteri Klebsiella sp sebanyak 2 (5,7%) dan Citrobacter sp sebanyak 8 sampel (22%). Rekomendasi yang diberikan dengan edukasi dan pemeriksaan secara rutin makanan dan minuman yang dijual untuk keamanan konsumen

Abstract

Stunting is caused by a lack of nutritional intake for a long time so that it can cause disturbances in physical development and cognitive function that can cause death. One of the factors that influence the occurrence of stunting in toddlers is the history of low birth weight. This study aims to examine the relationship between low birth weight (LBW) and the incidence of stunting in children aged 24-60 months in the Tabanan I Health Center Working Area in 2018-2019 using analytical research methods and case control study designs and using secondary data collection methods derived from the nutrition sections. The study sample was a total of 190 toddlers recorded in the stunting and LBW report at Tabanan I Health Center, during 2018-2019 who met the inclusion and exclusion criteria obtained using consecutive sampling technique. Data analysis was performed univariately and bivariately using SPSS version 25.0 with the Spearman correlation test. The results of the chi square test showed that the p value was less than the significant level (p < 0.05), it can be stated that there is an association between low birth weight and the incidence of stunting in children aged 24-60 months in the Tabanan I Health Center Working Area. The result of Levene's test is 0,184 (>0.05) which means that the variance of data between stunting and normal groups is homogeneous or the same. Conclusion toddlers who suffer from LBW have a 2,17 greater risk of experiencing stunting than toddlers who do not experience LBW.
