Abstract

The commonly used human blood group system is the ABO system. Determination of blood group is important in blood transfusion activities. The purpose of this study was to determine the frequency of the ABO blood group system and the frequency of the ABO blood group allele in students of the Biology and Science Education study program at UIN Sunan Ampel Surabaya. Determination of blood group was carried out by the Slide Test method which was carried out randomly with a sample of 90 people. Determination of blood group is done by the principle of agglutination that occurs between antigens and antibodies. The results showed the frequency of blood group ABO system: A (20%); B (24%); AB (10%); O (46%). IA allele frequency (0.13); IB (0.07); IO (0.8). The proportion of the highest frequency of blood type is blood type O. These results indicate that the distribution of blood type O among students at UIN Sunan Ampel Surabaya is relatively the same as the results of other studies conducted in Indonesia.

Abstract

The majority of people use pandan as a dye, food fragrance, and natural medicine because it contains secondary metabolites such as alkaloids, saponins, and phenolics. Therefore, this research aims to explore the secondary metabolites of Pandanus amaryllifolius using qualitative and quantitative methods. The research begins by taking samples of pandan leaves, which are then extracted and tested qualitatively and quantitatively. The qualitative test results showed that pandan leaf extract contained flavonoids, polyphenols, and tannins. In the quantitative test of pandan leaf phenolic compounds using a UV-Vis spectrometer with gallic acid concentrations of 80 ppm, 100 ppm, 120 ppm, and 140 ppm, Based on the quantitative test, the total phenolic content of pandan extract is 114 mg/L.
