Background: Natural preservatives are compounds produced by natural ingredients that can suppress bacterial growth and development. Natural preservatives are carried out because most of the preservatives circulating are chemicals and unsafe for the body. One of the natural preservatives is by using garlic extract (Allium sativum L).  Objective: This study is aimed to determine the effectiveness of the antibacterial garlic (Allium sativum L) as a natural preservative in fresh African catfish (Clarias gariepinus).  Method: This research used the Pour Plate iroculation method. African catfish (Clarias gariepinus) which is soaked with garlic (Allium sativum L) with a concentration of 7%, 14% and 21% for 30 minutes, then the fish will be kept at room temperature with a storage period of 24 hours and 48 hours and calculated growth in bacterial numbers with the Colony counter.  Result: Based on the research result, it was found that garlic extract (Allium sativum L) can obstruct the effectiveness of antibacterial in African catfish (Clarias gariepinus) at a concentration of 14%.

Infection is a disease caused by the presence of pathogenic microbes, including Staphylococcus aureus and Escherichia coli. Garlic (Allium sativum L.) has chemical contents such as allicin, alkaloids, flavonoids, saponins, tannins, and steroids, which can function as an antibacterial against Staphylococcus aureus and Escherichia coli. This study aims to determine the antibacterial properties of garlic extract powder against Staphylococcus aureus and Escherichia coli. This research is the initial stage of the development of herbal medicines to treat Staphylococcus aureus and Escherichia coli infections. The antibacterial activity test was carried out by the liquid dilution method. The concentrations used were 30 mg/mL, 40 mg/mL, 50 mg/mL, 60 mg/mL and 70 mg/mL. The results showed that the Minimum Inhibitory Concentration (MIC) against Staphylococcus aureus and Escherichia coli was 40 mg/mL and 50 mg / mL. Minimum Bactericidal Concentration (MBC) results for Staphylococcus aureus and Escherichia coli are 50 mg/mL and 70 mg/mL. Based on the Simple Linear Regression test, the R2 value of Staphylococcus aureus and Escherichia coli is 0.545 and 0.785, so it can be concluded that there is an effect of garlic extract powder on the growth of Staphylococcus aureus and Escherichia coli by 54.5% and 78.5%. Garlic (Allium sativum L.) extract powder has potential as herbal medicine against bacterial infections but requires further research to determine its effect in vivo.

Indonesian people have long used garlic as traditional medicine because it contains various chemical compounds that are beneficial to the body. In this study identification of garlicin and kuersetin compounds in garlic as an antibacterial. This study requires 500 grams of garlic each in wet preparations consist of fine garlic and garlic extract, and dry preparation consists of garlic powder. In addition, this research requires 2,1 liters of 96% ethanol. Garlic is dried at 400C with TMI Vacuum Oven and extracted at 250C. Garlic powder is made using Krisbow dry cabinet with a temperature of 1000F and a pressure of 10 Pa. Garlisin content was identified by GCMS Shimadzu TQ8030 and FTIR Perkin Elmer Spectrum Two UATR, while identification of quercetin using Shimadzu HPLC type UFLC. The result shows that the compound garlicin (C6H10S2) was found in the three samples with identical similarity levels. In addition, the three samples showed differences in kuersetin content. The highest kuersetin content was 458.729 ppm garlic extract while the lowest kuersetin content was 81.181 ppm fresh garlic. Both of these compounds have potential as antimicrobial compounds.

Blowflies are known vectors of many foodborne pathogens and unintentional human ingestion of maggots by meat consumption may lead to intestinal myiasis. In fact, the control of insect pests is an important aspect of industrial and home-made food processing and blowflies (Diptera: Calliphoridae), which are among the most important pests involved in the damage of meat products. Most spices, largely used in food preparations and industry, contain essential oils that are toxic and repellent against insects and exert antimicrobial activity. In this study, we assessed the electro-antennographic responses, the oviposition deterrence, the toxicity, and the repellence of the essential oils (EOs) of Allium sativum L., Salvia officinalis L., and Rosmarinus officinalis L. against the blowfly Calliphora vomitoria L. We tested the EOs antibacterial and antifungal properties and the efficacy of an A. sativum EO-charged mist sprayed in the tunnel entryway of a meat processing room to form an olfactive barrier against the entrance of flies. The results showed that the EOs are perceived by female blowfly’ antennae and exert an evident repellent activity against them completely deterring the oviposition for up to 24 h starting from the concentration of 2.5 μL cm−2 EO. The EOs also exhibited toxic activity by both topical application (LD50 from 0.44 to 1.97 μL insect−1) and fumigation (LC50 from 1.76 to 31.52 μL L−1) against adults of C. vomitoria and were able to exert a clear antimicrobial activity toward pathogens. Lastly, the EO-charged mist was able to reduce by about 40% the presence of Calliphoridae in the meat processing room of a dry-ham factory.
