Abstract

Diluent solution in microbiology analysis has a very important role in obtaining samples with the best number of microbes that can be counted from 30 to 300 colonies. Waste of air conditioner (AC) water which has not been utilized optimally has potential as a diluent solution. The purpose of this study was to determine the potential waste of AC water as an alternative diluent solution compared to some diluent solutions in the antibacterial test of Zedoary Rhizome tea against Escherichia coli (E. coli). Analysis potential of diluent solution using the plate count method, then used as a diluent solution in the anti-bacterial test of Zedoary Rhizome tea against E. coli ATCC 25922 by contact method for 24 hours and cell quantity was calculated by hemocytometer. This study used RAL with 4 treatment levels of diluent solution, namely: AC water, Pepton Water (PW 0.1%), physiological salts (0.85% NaCl) and demineralized aquades (Aq DM). The results showed that AC water thinners had a significant effect with PW and Aq DM diluents seen from the highest average E. coli cell value of 2.6 x 108 CFU/ml obtained in AC water thinners and the smallest value of 1.3 x 108 CFU/ml of Aq DM diluents. Tests of pH showed a 0.85% NaCl diluent solution of 6.95 was significantly affected by other diluent solutions. Antibacterial test showed that treat waste of AC water diluent had a significant effect with other diluents with an inhibition value of 60.81% and said to be bacteriostatic.

Abstract

The aim of this research was to determine the effect of dietary seaweed of Caulerpa sp. and Gracilaria sp. on blood glucose levels and histological pancreas of diabetic rats. A total of 28 male Wistar rats were used in this study. Rats were divided into 4 groups and given different diets i.e. PSN, PSA, PBN and PBS. Bioassay was conducted for 30 days. The analysis conducted on the macronutrient content of the seaweed flour as well as blood glucose levels on day 0, day 1 and day 30 after alloxan injection. At the end of the implementation of  bioassay, animal surgery were performed and pancreas organs were taken for histology observation. The results showed that  Gracilaria sp. and Caulerpa sp. had a crude fiber content respectively 20.48% and 12.47%. Blood glucose levels in all four groups of mice on day 0 ranged from 123.18 mg / dL - 131.96 mg / dL. Feeding PBN and PBS for 30 days lowered blood glucose levels of mice, respectively for 51.63% (from 384.4 mg / dL to 168.52 mg / dL) and 35.24% (from 328.05 mg / dL be 212.42 mg / dL). Histological observation showed that feeding PBN and PBS capable of helping the regeneration of pancreatic cells, thereby feeding both types of seaweed showed hypoglycemic effects in comparison with standard feed.
