Abstract

There has been research on the Bioacumulation of Cadmium in the Leachate, Sediment, Sepat fish and watercress within water around the final solid waste disposal (FWD) of Sukawinatan Palembang using Atomic Absorption Spectrophotometric (SSA) technique. This study aims to determine the distribution of cadmium contained in water ecosystem within water around the final solid waste disposal (FWD) of Sukawinatan, as well as bioconcentration factor (BCF) of the biotic compartement to the abiotic compartement . The way is done by wetdestruction sample. The resultant destruction solution was analyzed at a wavelength of 228.8 nm. The results showed that the concentration of cadmium in leachate Inlet 0,0099 mg/L until the Sedapat River 0,0010 mg/L, Sediment Inlet 0,0427 mg/Kg until Sedapat River Sediment 0,0051 mg/Kg, Sepat fish reservoir 0,0099 mg/Kg and Sepat fish Sedapat River 0,0096 mg/Kg along watercress reservoir 0,0042 mg/Kg over Sedapar river 0,0027 mg/Kg. So that distribution of cadmium for water and sediment compartment getting further from leachate inlet to Sedapat river is decreasing. The value of cadmium consentration in leachate is still below the threshold conformable in regulation of environment and forestry ministers no.59 of 2016 is 0,1 mg/L. Distribution  on the fish and watercress compartment also descreased to the Sedapat river. Consentration value on the fish and watercress also stil below the quality standard  in this SNI 7378;2009 for fish 0,1 mg/Kg and watercress 0,2 mg/Kg. While the value of BCF fish and BCF watercress  <100 is still in low category.

Abstract

Endophytic fungi can produce secondary metabolites of endophytic fungi isolated from host plants. The purpose of this study is to identify and analyze the sequencing of endophytic fungi isolates with ITS and Beta-tubulin markers and phylogenetic trees. The endophytic fungi isolate DKJ1, DKJ3a, DKJ3c and DKJ4 were successfully isolated from the cardia plant (Bellucia pentamera Naudin) indicated by Aspergillus niger group, Aspergillus fumigatus group and Penicillium sp. The results of the sequencing analysis of isolates DKJ1, DKJ3a, DKJ3c, and DKJ4 were successfully amplified with an annealing temperature of 54ºC with a pair of ITS1-ITS4 primers with a molecular weight of 570 bp and a Beta-Tubulin primer with an annealing temperature of 56.1ºC molecular weight of 550 bp. From the results of identification and analysis of DNA sequencing of endophytic fungi DKJ1, DKJ3a, DKJ3c and DKJ4 with the primary pair of ITS and Beta-tubulin shows that the phylogenetic tree is different from the species obtained. ITS DKJ1 isolates have similarities with the species Aspergillus piperis CBS 112811, ITS DKJ3c has similarities with the species Aspergillus flavus var flavus strain ATCC 16833, ITS DKJ3a has similarities with Penicillium rolfsii strain NRRL 1078 species and ITS DKJ4 has similarities with Penicillium oxalicum NRRL 787 species. Whereas isolate from DKJ1 Beta-Tubulin has similarities with NRRL 4875 Aspergillus tubingensis species, DKJ3c has similarities with species of Aspergillus novoparasiticus strain DTO 223-C4 and DKJ4 has a similarity with Penicillium guaibinensis species. But there are similarities based on Cluster A (Aspergillus Group) and Cluster B (Penicillium Group) on phylogenetic trees.
