Abstract

Food safety and sustainable food production is an essential parts of the sustainable development goals of protecting the health and well-being of humans, animals, and the environment. Foodborne diseases are a significant cause of morbidity and mortality, particularly with the global crisis of antibiotic resistance. Bacteriophages as a biocontrol are a promising alternative for reducing contamination from pathogenic bacteria in food such as Escherichia coli, Bacillus cereus, Staphylococcus aureus, and Listeria monocytogenes. Bacteriophages are natural predators of bacteria that are harmless to humans and animals and are found in various environments, thus have been recognized as promising antimicrobial agents to help control specific bacterial pathogens in food production. Several bacteriophages have been applied in food to reduce the number of pathogenic bacteria. The results of this application show the efficacy of bacteriophages as biopreservation agents against foodborne pathogenic bacteria.

Abstract

Dental caries is an infection disease of tooth tissue caused by Streptococcus mutans bacteria. Atsiri is essential oil is a liquid-shaped compound that is thought to have potential as an antibacterial. The purpose of this study was to determine the antibacterial potential of essential oil of limau lime in controlling Streptococcus mutans bacteria. The antibacterial test in this study used disk disfussion method with 8 treatment groups and 4 replications is 5 concentrations of atsiri oils, 1 positif disc amoxicillin antibiotic, 2 negative control with DMSO and aquades. The data obtained were analyzed with normality test, Anova test and BNT test. Isolation of atsiri’s oil of limau lime in this study using the method of steam-water distillation. Streptococcus mutans bacteria were isolated from dental caries patients and tested using macroscopic, microscopic, gram staining, and biochemical methods. The study found that the atsiri oils of limau lime has antibacterial activity in vitro against Streptococcus mutans bacteria, as evidenced by the formation of an inhibit zone. Concentration as 100% with 15.38mm inhibitory zone diameter is the most effective concentration to inhibit the growth of Streptococcus mutans bacteria. The statistical analysis revealed a significant influence between the treatments at the 5% significance level.

Abstract

Glacilaria sp. is one type of red algae that is widely found in Indonesia. Red algae has anti-microbial, anti-bacterial, anti-viral, anti-fungal, and other benefits. Endophytic microbes associated with seaweeds such as bacteria and fungus are thought to be able to produce the same bioactive compounds as their host, seaweeds. Several studies have also shown that the antibacterial activity of endophytic microbes can inhibit pathogenic bacteria. This study was conducted to identify endophytic bacteria present in Glacilaria sp. in inhibiting the growth of pathogenic bacteria (Vibrio sp. and S. aureus). Endophytic bacteria found in Gracilaria sp. isolated and tested for antibacterial activity using Staphylococcus aureus and Vibrio sp. bacteria. with disc disc method. the results showed that endophytic bacteria of the red algae Gracilaria sp. has antibacterial activity against bacteria S. aureus and Vibrio sp. It has inhibitory zones of 8 mm and 7.6 mm, respectively

Abstract

Vegetal food is the most important resource for herbivores. The study of food consumed by bird community in Indonesia, especially in urban environments is needed to provide an overview of the ability of City Parks to support bird communities. The aim was to determine the urban park vegetation in the Lapangan Banteng park as a potential food source for urban birds, especially frugivores, nectarivores and granivores. The study was conducted in September until December 2018 . Data were analyzed using Rstudio and ImageJ. The results showed that there were 7 species of birds consisting: four species of granivores (Passer montanus, Streptopelia chinensis, Lonchura punctulata, and Pycnonotus aurigaster) and three species of frugivores (Psittacula alexandri, Dicaeum trochileum, Treron vernans) which were observed to use plants as food resource Lapangan Banteng park. Birds used 30% of trees (Syzygium polyanthum, Melaleuca leucadendra, Ficus benjamina) and 70% of herbaceous ground cover (Arachis pintoi., Phoenix sp., Pennisetum purpureum, Axonopus compressus, Cynodon dactylon, Cyperus rotundus, and Eleusine indica). The availability of sufficient natural food in nature will have an impact on both bird conservation and the environment. The availability of natural food will improve bird conservation and ensure the sustainability of urban biodiversity.

Abstract

Cooking oil is a human need that is increasing over time resulting in wasted cooking oil. One of the efforts to reduce negative effect of used cooking oil is the use of activated carbon in the refinery process. The aim of this study was to determine the hepatotoxicity of used cooking oil treated with activated carbon of bagasse on rat livers. The method used true experimental laboratory with Post Test Only with Control Group Design. White rats were divided into 4 treatment groups. Positive control, given 0.2 ml of used cooking oil. Negative control, given 0.2 ml of packaged cooking oil. Group 3 was given 0.2 ml of used cooking oil mixed with 5% activated carbon. Group 4 was given 0.2 ml of used cooking oil mixed with 15% activated carbon of bagasse. The liver enzyme of SGPT-SGOT was measured by spectrophotometry and analysed by ANOVA. The concentration of bagasse-activated carbon in used cooking oil affected the levels of SGOT-SGPT and rats weight. The lowest levels of SGOT were obtained in used cooking oil treated with 5% activated carbon bagasse (18.85 ± 0.544 U/L). Application of bagasse-activated carbon in used cooking oil can reduce the risk of hepatotoxicity in mice.
