Abstract

Pomegranate (Punica granatum) is a plant that contains secondary metabolite compounds that can be used as medicinal content. Black pomegranate contains the highest secondary metabolites compared to red pomegranate and white pomegranate, the skin of the pomegranate contains flavonoids, phenols, tannins, and saponins. This study aims to determine the antioxidant activity of black pomegranate peel extract (Punica granatum L.) with the DPPH method. DPPH method is a method to determine the antioxidant activity in the sample by looking at its ability to counteract the free radical compound 2,2-diphenyl-1-picrylhydrazyl. The results of testing the antioxidant activity of black pomegranate skin (Punica granatum L.) produced an IC50 value of 47.51 ppm which can be concluded that black pomegranate skin is classified as very strong. This research is important because there has not been much research on black pomegranate, especially its skin, so there is a need for additional expansion and renewal of the species. In addition, it can be used as the main basis for the advancement of natural materials, especially in the field of health.

Abstract

The purposes of this study were to analyze the relationship between the characteristics of accidents and road safety facilities such as road signs, road markings, and lighting lights, and to analyze the characteristics of traffic accidents on Soekarno-Hatta Bypass Road included  type accident and factors causing of the accident. The surveys in the field were conducted to obtain the primary data about road safety facilities, however the secondary data were obtained from the Bandar Lampung police station in the form of accident data per month from 2014-2017. The results showed that there were still inadeguate road safety facilities on the Soekarno-Hatta Bypass road, such as lighting and road markings.The characteristics of accidents based on the factors that cause the accidents were human factors (85.28%). The types of accidents were are front-rear accidents (28.8%). Keywords: Accident Characteristics, Arterial Road, Road Safety Facilities
