Angka Paling Mungkin (Most Probable Number/MPN) Coliform Sampel Minuman Lidah Buaya Di Pontianak
Get PDFAloe vera drink is one of the processed drinks made from the aloe vera leaves, washed until the mucus is reduced and boiled with water. Good drinking water should not contain pathogenic bacteria or organisms that can endanger human health. Coliform is one of the bacteria that can cause disease in humans and is used as an indicator of the presence of pathogenic bacteria. This study aimed to find out the most probable number (MPN) Coliform bacterial in aloe vera drinks which has sold at the location of the sale on Budi Utomo Street, Pontianak City. Sampling used the random sampling method. The MPN test results obtained the lowest MPN/mL index value of 0.091/mL in the samples purchased at the minimarket, while the seven samples obtained at the sales location showed the highest MPN/mL index value of> 24.00/mL. It showed that the eight samples reached over the normal limits listed in SNI 01-3839-1995 based on the Republic of Indonesia Ministry of Health No. 907 / MENKES / SK / VII / 2002 concerning the requirements and supervision of the quality of drinking water which is not more than 0/100 ml

Aktivitas Antifungi Isolat Actinomycetes dari Sumber Air Panas Ai Sipatn Lotup Sanggau Terhadap Isolat Hortaea werneckii (T1)
Get PDFPathogenic fungi cause health problems especially the skin infection caused by Hortaea werneckii causes of tinea nigra skin disease. One of the method minimizes the problems and against the growth of Hortaea werneckii can use the active material from Actinomycetes bacteria as the antifungal. This research was to aware the kind of Actinomycetes bacteria that have the most potential as antifungal against the Hortaea werneckii, the effect of metabolic volume composition and incubation time of Actinomycetes bacteria against the Hortaea werneckii (T1). Antifungal activity test used the filtration method of Actinomycetes bacteria with parameters based on incubation time and volume comparison of metabolites concentration. Antifungal activity test of 11 isolates Actinomycetes bacteria produce six isolates Actinomycetes bacteria as the most potential antifungal and the percentage of the effect difference among the treatment against Hortaea werneckii (T1) are Thermoactinomyces sp. (H24) 39,98%, Thermoactinomyces sp. (H21) 29,11%, Thermobifida sp. (S311) 21,14%, Streptomyces sp. (S211) 34,21%, Actinomadura sp. (S21(2)) 24,70%, dan Nocardiopsis sp. (H22*1) 33,03%. Bacteria isolate Thermoactinomyces sp. (H24) have a significant percentage of antifungal with an average 97%, as a difference of the effect among treatments are 39,98%. The metabolites produced by Actinomycetes cause Hortaea werneckii (T1) growth to be inhibited and damage cells structure their

Pertumbuhan dan Kandungan Pigmen Tanaman Keladi (Caladium bicolor Aiton Vent) pada Tanah yang Merkuri (HgCl2)
Get PDFMercury is one of the heavy metals and is toxic which causes a decrease in pH and soil fertility. Keladi (Caladium bicolor) is able to grow and adapt to heavy metal contaminated soil because it has a tolerance mechanism and contains antioxidant pigments. This research aims to determine the effect of mercury on the growth and the content of C. bicolor pigment. This research was conducted from January 2017 until March 2017 at Greenhouse and Biology Laboratory of the Faculty of Mathematics and Natural Sciences of Tanjugpura University Pontianak. The research was a completely randomized design with 5 replications consisting of control, concentrations HgCl2 300, 350, 400 and 450 ppm. The results showed that the concentrations of HgCl2 at 350, 400 and 450 ppm decreased the chlorophyll pigment content, wet weight and dry weight of C. bicolor. The concentrations of HgCl2 at 300 ppm increases the anthocyanin pigment content and HgCl2 had no significant effect on carotenoid pigment content
