Various herbs are used as analgesic, anti-inflammatory, anti-bacterial, anti-fungal, expectorant, anti-plaque and odorant. Sentul is an edible fruit and is also used in traditional medicinal herbs which can treat diarrhea, relieve fever, and as an anthelmintic. Sentul bark methanol extract can inhibit the growth of fungus Candida albican by 39.65%. In addition, the ethyl acetate extract of the sentul leaves also has anti-bacterial activity. The aim of this study is to determine the effect of fractionation with different types of solvents on the phytochemical compounds of Sentul fruit peel in Bali province. This research is an experimental study in a laboratory with qualitative and quantitative analysis models of chemical compounds. This research was carried out from March to August 2021. The research location was carried out in the laboratory of the Faculty of Food Technology, Udayana University. Sample criteria was old Sentul peel, about 30 kilograms. Data was collected based on the results of examinations from the Laboratory of the Faculty of Food Technology, Udayana University which subsequently analyzed qualitatively and descriptively. From several phytochemical compounds, flavonoids, saponins and tannins are aromatic hydroxyl groups that act as antibacterial. Therefore, seen from the highest levels of flavonoids, saponins and tannins, aqua fraction of Sentul ethanol extract is the best treatment with flavanoid levels of 11476.16 mg/100g QE, tannins 88.605 mg/g and saponins 6.862 mg/g.
The imbalance number of rapid vehicles with transportation facilities has become the problem. In Denpasar, Indonesia, the congestion during peak hours happens so often. Based on the department of transportation in Denpasar, Indonesia, the number of vehicle ownership in Bali is 4.1 million in condition with a ratio of one resident to one vehicle with the current population of Bali Province approximately 4.2 million. Our study aim to measure the air chemical parameters of CO, O3, SO2, NO2 and the physical parameters of the noise level. The research population is the atmosphere environment in the Denpasar City area. The research sample points were taken in the city center and the outskirts of Denpasar, with a total of 27 sample points. We employed impinge to get the airborne chemical gases and it is all analyzed with a spectrophotometer. We used a sound level meter to measure the ambient noise level. The data analysis was performed with free sample t test. The average ambient air chemistry obtained CO 517.34 µgr/Nm3, O3 0.17 µgr/Nm3, SO2 61.46 µgr/Nm3 and NO2 2.51 µgr/Nm3 and an average noise level 67.66 dBA. The number has found below the requirements Environmental Quality Standards and Environmental Damage Standard Criteria by Bali Governor. There is a difference in the mean parameters of CO, SO2, NO2 and ambient noise level in the downtown area. The average CO is 757.15 µgr/Nm3, SO2 67.60 µgr/Nm3, NO2 3.77 µgr/Nm3 and the noise level is 68.53 dBA with Denpasar outskirts mean CO 217.57 µgr/Nm3, SO2 53.79 µgr/Nm3, NO2 0.95 µgr/Nm3 and noise level 66.57 dBA. There is no difference in the average ambient O3 in the city center area with an average of 0.22 µgr/Nm3 with the outskirts of Denpasar an average of 0.11 µgr/Nm3.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
