Abstract

Lactic acid bacteria (LAB) interest promises a prospective dietary approach for enhancing the management of blood sugar levels in individuals diagnosed with diabetic and those presenting with pre-diabetic conditions. This review article summarizes the available evidence on the role of LAB in blood sugar regulation, focusing on the mechanisms underlying its effects and relevant research results. LAB supplementation has been shown to improve glucose tolerance and insulin sensitivity in animal and human studies, as well as to reduce fasting blood glucose levels in individuals with type 2 diabetes. Potential mechanisms underlying the effects of LAB on blood glucose control include improving insulin sensitivity, reducing inflammation, and improving intestinal barrier function. However, further supporting studies are needed to fully understand the optimal strain and dose of LAB for blood glucose control and to elucidate the mechanisms by which they exert their effects. Despite promising results, the safety and potential side effects of LAB supplements should also be carefully considered. Overall, this review highlights the potential of LAB as a dietary strategy for blood sugar regulation in individuals with diabetic and pre-diabetic.

Abstract

Bidara arab leaves (Ziziphus spina-christi L), contain various potentially health-beneficial compounds, including antibacterial agents. The aim of this study was to determine the antibacterial activity of ethanolic leaf extract of Ziziphus spina-christi L. in inhibiting the growth of pathogenic bacteria. The leaves of Bidara arab were macerated using 70% ethanol, followed by the agar diffusion method to evaluate the antibacterial activity. Subsequently, bioautography analysis using TLC and phytochemical screening of the active extract were conducted. The results of the antibacterial activity test using the ethanolic leaf extract of Ziziphus spina-christi L. showed antibacterial activity at a concentration of 2 mg/paper disk, with inhibition zone diameters of 19.44 mm for Bacillus subtillis, 17.06 mm for Escherichia coli, 16.32 mm for Staphylococcus aureus, 12.96 mm for Pseudomonas aeruginosa, and 14.50 mm for Salmonella typhi. The TLC-bioautography analysis of the ethanolic leaf extract of Ziziphus spina-christi L. against Bacillus subtillis exhibited inhibition at Rf 0.96, Escherichia coli at Rf 0.31, Staphylococcus aureus at Rf 0.89, while Salmonella typhi did not show inhibitory activity. Phytochemical screening results indicated that the ethanolic leaf extract of Bidara arab is suspected to contain flavonoids, terpenoids, and tannins.

Abstract

Identification of the quality of void water after coal mining needs to be carried out in order to utilize the void as a place to raise fish. Identification of water quality, in the form of physical and chemical water. Physical and chemical parameters can influence the survival of cultivated biota, so research needs to be carried out to identify both physical and chemical water parameters related to aquaculture. The research method is taking and measuring water samples in situ and ex situ. Measurements were carried out at three (3) sampling points, sampling four times. The parameters observed are temperature, TSS, pH brightness, O2, BOD, COD, NO3, NO2, NH3, H2S. Descriptive analysis of water quality and comparing the quality standards of Provincial Regulations. East Kalimantan Number 2 of 2011, concerning Water Quality Management and Water Pollution Control. APPENDIX V, Class III The results of the water quality analysis physically show that the temperature is 29.5 –31oC brightness 135 – 285 Cm, TSS 13.75 – 27.5 mg/L, Chemical pH 7.42 – 7.68, O2 4.26 – 4.84 mg/L, BOD 0.64 – 1.84 mg/ L, COD 2.96 – 5.93 mg/L, NO3 0.026 – 0.049 mg/L, NO2 0.002 – 0.006 mg/L, NH3 0.01 – 0.13 mg/L and H2S 0 – 0.0087 mg/ L. Water quality parameters, both physical and chemical, still comply with the quality standards of East Kalimantan Province Regional Regulation Number 2 of 2011 concerning Water Quality Management and Water Pollution Control. The condition of post-coal mining void water, both physically and chemically, is still suitable for aquaculture.

Abstract

This research aims to examine the phytochemical content and antioxidant potential of 70% ethanol extract of Centella asiatica leaves and the results of fractionation using 3 types of solvents with different polarities. Centella asiatica leaves were extracted by maceration method, then fractionation and phytochemical screening were carried out. Test the total phenolic content with the Folin Ciocalteu method and antioxidant activity with the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. The yield of 70% ethanol solvent maceration, n-hexane fraction, ethyl acetate fraction and methanol fraction were 18.782%, 3.05%, 6.19%, 92.46%. Phytochemical screening of 70% ethanol extract of Centella asiatica leaves contains flavonoids, tannins, phenolics, alkaloids and steroids. The n-hexane fraction contains alkaloids, tannins, phenolics and triterpenoids. The ethyl acetate fraction contains flavonoids, saponins, tannins, phenolics, alkaloids and steroids. The methanol:water fraction contains alkaloids, flavonoids, saponins, tannins, phenolics and triterpenoids. The total phenolic content test of 70% ethanol extract, n-hexane fraction, ethyl acetate fraction and methanol:water fraction was 12.773 ± 0.479 mg GAE/g, 1.182 ± 0.124 mg GAE/g, 18.334 ± 0.305 mg GAE/g, 10.211 ± 0.247 mg GAE/g. Antioxidant activity of 70% ethanol extract, n-hexane fraction, ethyl acetate fraction and methanol:water fraction with IC50 values of 77.4 ppm, 2122,5 ppm, 45.6 ppm and 126 ppm.

Abstract

This study aims to determine the toxicity of soursop leaf extract (Annona muricata L.) and patchouli leaf extract (Pogostemon cablin Benth.) on the mortality of the American cockroach (Periplaneta americana). The extract was prepared using the maceration method, using distilled water as a solvent. Soursop and patchouli leaf extracts with a concentration of 5% were sprayed as much as 2 ml on each American cockroach. The results of the study were cockroach mortality data for 1-120 hours with observations every 1, 3, 6, 12 and 24 hours. As for the results obtained, the administration of soursop leaf extract cockroach mortality at the 24th hour was 66.67% and at the 48th hour 100% cockroach mortality. Whereas in the administration of patchouli leaf extract cockroach mortality at the 96th hour was 66.67% and at the 120th hour 100% cockroach mortality.
