Abstract

Pathogenic 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.

Abstract

Lemna minor and Hydrilla verticillata are types of water plants that have the potential to have the ability to process and improve the quality of polluted water. The purpose of this study is to determine the ability of Lemna minor and Hydrilla verticillata in improving the quality of laundry wastewater. The study used a completely randomized design (CRD) method with six treatments and three replications. The study was carried out on test media in the form of 5 liters of laundry wastewater with L. minor (L) 100 g, H. verticillata (H) 100 g, and combination treatment of both plants (L1H1, L1H2, L2H1) in weight L1H1 (50 g : 50 g), L1H2 (33 g : 67 g) and L2H1 (67 g : 33 g) for 14 days after acclimation for one week. The combination of L. minor and H. verticillata with a ratio of 1: 2 was able to reduce the highest Total Suspended Solid (TSS) and Total Dissolved Solid (TDS) of laundry wastewater with a decrease of 52.87% and 4.02% and increase dissolved oxygen (DO) of 7.13 mg/L. The highest decrease in chlorine occurred in L. minor and H. verticillata treatments with a ratio of 1:1 of 0.110 mg/L. All treatments of L. minor and H. verticillata both singly and in combination have not been able to reduce the phosphate content in laundry wastewater on day 14 of treatment.
