The Utilization of Lamtoro leaves (Leucaena leucocephala L.) Extract as an Alternative Nitrogen Source on The Formation of Nata de Soya Cellulose from Tofu Whey Waste

Nata is not only made from coconut water; it is also possible to produce it from other raw materials. In our study, nata de soya has successfully made using tofu whey as raw material. Research focused is on the utilization of lamtoro (Leucaena leucocephala L.) leaves as an alternative source of nitrogen in addition to the use of ammonium sulphate and urea which have generally been used in nata production. The selected research method was experimental. First, the Lamtoro leaves were mashed and then inserted into the medium and cooked until it boils. The medium was incubated at room temperature for 12-14 days and the thickness of the cellulose was then measured. The purpose of this study was to determine the effect of the using of lamtoro leaf extract (Leucaena leucocephala L.) as an alternative source of nitrogen for nata de soya cellulose formation. The optimization of pH and nitrogen contentration have been obyained. Three types of formula have been arranged, i.e. 1⁄2 of the control nitrogen concentration, equivalent, and 2 times of the control nitrogen concentration, to provide the variation concentration. Results found that the optimum pH was 3 and the optimum nitrogen concentration was ½ of the control nitrogen level. Nata de soya has then prepared using optimum condition of pH and nitrogen concentration. The maximum average of nata de soya thickness was 7.6 mm. In addition to leveraging the ability of medicinal plants and reducing the use of chemicals in the food processing, the use of alternate sources of nitrogen may also be adopted in the wider cellulose nata application.

The Sensitivity Test of Mycobacterium tuberculosis to Snail Seromucoid and Chitosan in vitro

Tuberculosis (TB) is an infection caused by M. tuberculosis (MTb) and is transmitted through droplets of phlegm in the air from patients or those suspected of having TB. In general, treatment for TB is done with anti-tuberculosis drugs (ATDs), specifically streptomycin, isoniazid, rifampicin, and ethambutol (SIRE) that takes a long time due to the level of resistance of MTb bacteria. The resistance of MTb triggers ATDs based on natural bioactive compounds. Chitosan as a result of chitin deacetylation can function as an antimicrobial agent because it is polycationic, which is biodegradable, biocompatible, and non-toxic. Snail (Achatina fulica) seromucoid contains antibacterial bioactive compounds, namely glycans, peptides, glycopeptides, achasin protein, and chondroitin sulfate. This study aims at testing the sensitivity of MTb isolates against snail seromucoid and chitosan in vitro. This research applied the experimental research method. MTb isolates were obtained from sputum samples of patients suspected of TB at the Surakarta Regional Public Hospital (RSUD Surakarta). The results of screening for MTb were positive, based on the microscopic examination of MTb using the Ziehl Nelson (ZN) method, the MPT 64 rapid test, and the quick molecular test using the Genexpert method. The research was completed through several stages, including the preparation of a suspension of germs with a concentration of 1 mg/ml or Mc. Farland 0.5-1.0; preparation of the stock solution and working solution (WS); drug sensitivity test (DST) against snail seromucoid; chitosan and ATDs (SIRE) on Lowenstein Jensen (LJ) media; and incubation at 37°C for 3-4 weeks. The results were interpreted on day 28 or day 42. The results have revealed that MTb isolates are 100% resistant to snail seromucoid and 2% chitosan. This study concludes that MTb isolates from suspected TB are resilient to 100% snail seromucoid and 2% chitosan.

The Effectiveness of Red Grape (Vitis vinifera) Seed and Skin Extract Treatment on Staphylococcus aureus Bacteria that Causes of Urinary Tract Infections in Pregnant Women Examined by using White Mice (Mus musculus)

Urinary tract infection or what is often called a UTI is an infectious disease of the urinary tract epithelium and is commonly caused by gram-positive bacteria, namely the Staphylococcus aureus, with a prevalence rate of 68 million patients in the world and 1.2 million patients in Indonesia. The diagnosis of UTI is established with a positive urine culture significance value ≥105 (CFU)/ml. The existing clinical management for cases of urinary tract infections in pregnant women uses amoxicillin to kill gram-positive bacteria, such as Staphylococcus aureus. However, there have been 469 cases of antibiotic resistance in pregnant women in Indonesia due to the non-compliance of using antibiotics for urinary tract infections. Vitis vinifera can be used as an alternative to natural bactericidal resveratrol containing anthocyanidin to kill gram-positive bacteria. This study used 28 white mice (Mus musculus) aged 6-21 weeks and weighing 120-200 grams injected with Staphylococcus aureus. The 28 subjects were divided into 4 groups, each of which consisted of 7 mice. The mice received K1 treatment with 250 mg/kgBW of amoxicillin and treatments with 200, 300, and 500 mg/KgBW red grape seed and skin extract. Before treatments were given, a pre-test was conducted to ensure that the results were not biased. Post-test was also performed after the Staphylococcus aureus injection, which was measured after 5 days of urine culture that reached 107 CFU/ml. The treatment in P3 using 500 mg/KgBW of red grape seed and skin extract contributed to the smallest result with 102 Cfu/ml, equals to the result produced by giving 250 ml/KgBW of amoxicillin.
