Abstract

AbstractSail River is one of the Siak watersheds which has high TSS levels. This study aims to determine the decrease in TSS levels using the different density of biorafia (plastic rope that functions as a filter). This research was conducted on the Sail River, from March to April 2019. The method used was CRD with 3 different biorafia densities: P1 (low density), P2 (medium density) and P3 (high density), with 3 replications. Sampling is done before passing the biorafia (inlet) and after passing through the biorafia (outlet). The highest reduction in TSS levels was found at moderate density (190 mg / L) with a decrease in effectiveness (EP) of 96,9%. The density of different biorafia does not significantly influence the decrease in TSS levels in the Sail River water. Keywords : Biocord, Biorafia, Suspended Solid and Bacteria

Abstract

Abstract The quality of peat water in general is relatively low and it is  needed to be treated by using a coagulation system.  Mixture of lime, alum and bentonite might be used as coagulant agents. This study aims to determine the effectiveness of different dosages of lime, alum and bentonite in improving   the quality of peat water. Peat water samples were obtained from the Kualu Nenas Village, Kampar, Riau. The was CRD method applied and   data  were analyzed using Analysis of Variance (ANOVA) with SPSS version 17.0 software. If there is a significant effect, a   Duncan's Multiple Range Test 5% level of (DMRT) is applied. There were 4 treatments and 3 replications applied namely P1 (0.50 g lime + 1.36 g alum + 0.34 g bentonite), P2 (0.50 g lime + 1.02 g alum + 0.68 g bentonite), P3 (0.50 g lime + 0.68 g alum + 1.02 g bentonite), P4 (0.50 g lime+ 0.34 g alum + 1.36 g bentonite). In each treatment, a liter of peat water was treated with the mixture for 20 minutes. From these results it can be concluded that a mixture of lime, alum and bentonite can improve the quality of peat water. The best treatment was provided by  P2 and the result was pH 7.3, color 32.6 Pt/Co, turbidity 2.10 NTU and organic 37.9 mg / L.Keyword : Alum, Coagulation, Floculation, Turbidity, Organic matters

Abstract

AbstractThis study is aimed to learn the capabilities of Trachelomonas sp. as biotaqualifies for metal toxicity test. This research is done for 17 days by seeing an entireliving phase of Trachelomonas sp.  in the growth curve. A cell density analysis fromTrachelomonas sp.calculated using a microscope.This result indicate that there are4 living phases of Trachelomonas sp.  it’s composed of phases lag, an exponentialphase, stationary phases and phases leading to death. Trachelomonas sp. qualifiedas a test biota for a heavy metal toxicity test using phytoplankton according to Asean-Canada Cooperative Programme on Marine Science Phase II. This is seen from thegrowth of cell density that exceeds the minimum limit on the 4th day of inoculationgrowth curve or at the beginning of an exponential phase with density of cell 1,01 x106cell.mL-1.Keywords : Density.
