Abstract

The research was conducted to determine the quality of the kanji pedah by counting total number and percentage of Aspergillus flavus and Aspergillus niger. It had been done since March from to October 2010 in Microbiology Laboratory of Biology Departement FMIPA Unsyiah. Kanji pedah as the sample was taken from Meunasah Mesjid Syamtalira village, Aron Subs-district of North Aceh. This research used sample from variety storage time groups range 3-7 days; 5-7 months; 9-12 months; and 15-18 months. Data were analyzed in descriptive and compared with the quality standard from Directorate General of National Agency of Drug and Food Control (Dirjen BPOM RI). The result showed the entire sample had fungi with ranged 1.45-63.7x102. The amount of fungi exceeds the quality standard already established by the National Agency of Drug and Food Control No. 05018/KBPOM/2001: 50 colony/g. Also Aspergillus flavus was found with range from 3%-27% meanwhile Aspergillus niger was found with range from 21,1%-40,9%.

Abstract

Abstract. Saga (Abrus precatorius L.) have been used by Indonesian community as a traditional medicine. The research aims to determine the activity of the methanol extract of saga leaves to inhibit the growth of clinical Streptococcus pneumoniae growth. Inhibition tests was done with casting cup method. The results showed that the methanol extract of saga leaves at a concentration of 37,5; 50; 62,5; 75 and 87,5 mg/mL formed growth inhibition zone of clinical S. pneumoniae with consecutive average of 0,5; 1,75; 2,82; 4,00; and 4,82 mm. Based on the results of the research can be concluded that the methanol extract of saga leaves had activity in inhibiting the growth of clinical S. pneumoniae isolates with low category.  Key words: Abrus precatorius L., Clinical Streptococcus pneumoniae, Methanol extract*Judul ini telah dipresentasikan pada Seminar Nasional: Indonesian Students Conference on Science and Mathematics(ISCSM) 11-12 November 2015, Banda Aceh Indonesia
