Abstract

Some reports have shown that ice cubes may contain Enterobacteriaceae bacteria. This descriptive, observational research aims to analyze the microbiological quality of the ice cubes served at three selected restaurants  (1,2,3).  Three  samples  of  ice  cubes  were  rinsed  with  steril  water,  left  melted,  and  diluted serially.  Each  diluted  sample  was  inoculated  into  MacConkey  Agar  and  EMB  Agar  with  pour  plate method duplo. The data collected were the number of colonies (interpreted as cfu or colony forming unit) of Escherichia coli and other Enterobacteriaceae bacteria. The species of selected colonies were identified by  biochemical reactions. The result showed that sample 1 contained 3 cfu/ml Escherichia coli and 5 cfu/ml Pseudomonas  sp.  Sample  2  contained  10  cfu/ml  Escherichia  coli  and  4  cfu/ml  Pseudomonas  sp.,  but sample 3 didn’t contain Escherichia coli and other Enterobacteriaceae bacteria members. It is concluded that ice cubes from restaurant 3 met the requirement for drinking water, whereas those from restaurants 1 and 2 did not.  Keywords: ice cubes, Escherichia coli, Pseudomonas sp.

Abstract

Cisplatin is a chemotherapy drug that had nephrotoxicity side effect which marked with the increase of urea and creatinine. Kesum (Polygonum minus Huds.) is one ofthe potential herbs that can be used to decrease urea and creatinine concentration. Thepurposes of this research is to find out the secondary metabolite contents of kesumleaves methanol extract and the activity of urea and creatinine concentrationreduction which rats were treated to have nephrotoxic with induction of cispatin.Kesum leaves extraction was done by maseration method using methanol solvent.Phytochemical screening test was perfomed with a tube to detect the compound inkesum leaves extract. The rats were divided into 5 groups which are non-treatedgroup (CMC1%), cisplatin control group, dose 1 group (8,664 mg/200 grBW), dose 2group (17,328 mg/200 grBW), and dose 3 group (34,656 mg/200 grBW). Theconcentration of urea and creatinine were checked at day 10 after the induction usespectrophotometer UV-Vis. Data were analyzed with Oney Way ANOVA and PostHoc Test Multiple Comparisons-Tukey HSD test. Phytocemistry screening showsthat kesum leaves methanol extract compound alkaloid, polyphenol, tannin,flavonoid, triterpenoid and saponin. The results show that dose 1, dose 2, and dose 3can decrease urea and creatinine concentration which indicate that it has potency toreduce the side effect of chemotherapy agent cisplatin.

Abstract

The aim of this study is to analyze the factors that influence financing policy. Financing policy as the independent variable consist of dividend anddebt policies. The factors that influence the dividend policy are business risk, profitability, and growth. Debt policy influence by dividend, business risk,profitability, and fixed asset. Toestimate relation between these factors, this study used Seemingly Unrelated Regression (SUR) because the debt and dividend model have same error term. Research object are companies in manufacture industry that listing in Indonesian stock Exchange that paid dividend in minimum 4 periods in research periods. The result of the analysis indicates that profitability have a significant influence toward dividend policy. Result for debt policy are business risk, profitability, and fixed asset have a significant influence toward debt policy. The result also shows that profit has positive significant effect to dividend, which indicates the ability of the firm to pay higher dividend while their profit increased. Risk and profit also show positive effect to debt. Firms with higher profit will have higher debt, however their risk also increased in significant positive relationship.
