The results showed that the extract of 200 ppm inhibited fatty acids oxidation by 80.40% and IC50 for free radical scavenging was 85.82 ppm. There was no significant different (α = 0.05) inhibition of unsaturated fatty acids oxidation between the sample and α-tocopherol at 200 ppm. This study suggested that the leaves extract of P. crocatum has a potential natural antioxidant 2.2 2.7 5.3 574.07 6.5 BAHAN<BR>2. MORTAR (MATERIA) BIOLOGI - STUDI DAN PENGAJARAN BIOLOGY BS The Bible Bekasi Bogor Certain bacteria that induce biological ice nucleation are suspected to play an important role in condensation and ice nuclei formation in clouds. Those bacteria can produce biological ice nucleator1 Ekonomi Umum INA bacteria were isolated from rain-water and air between March to May 2008 from Jakarta Ilmu dan Teknologi Pangan Manajemen Kelas PERTUMBUHAN<BR>2. INDONESIA - ECONOMIC CONDITIONS Sistem Informasi Tangerang The excessive number of free radicals in human body could increase lipid peroxides and causes a variety of degenerative diseases. Piper crocatum is a plant containing natural chemicals that may have an antioxidant ability to inhibit fatty acid oxidation and reduce free radicals and 1.8%. The highest incidence of INA bacteria were from rain-water and air found in sample from Jakarta and then followed by the samples from Bogor. It was shown that the percentage of INA bacteria from rain-water was higher than air for all of the samples from different areas. The isolate from Jakarta (isolate A32) which had the highest activity for ice nucleation and 6.4% respectively and Depok. The percentage of INA bacteria from rainfall for those area are 19.4 however revealed 100% similarity with Pantoea sp. The presence of INA bacteria in rain-water and air might play an important role in nucleation process which is required for rainfall induction the objective of this research is to study the ability of ethanol extract of P. crocatum as an antioxidant. The leaves of P. crocatum (25 g) were extracted with 100 ml of 70% ethanol. Antioxidant activity was measured by thiobarbituric acid method and compared with 2 there is no published scientific reports up to now. Therefore which is a protein and usually found on leaf surface and air. Most studies on INA bacteria were conducted in subtropical areas. In this study while percentage for air are 9.5 with the temperature classification at -2.7 oC
