Electroplating wastewater containing metal Cr (VI), which has a high toxicity. An alternative treatment is absorbed using microalgae Chlorella sp. Chlorella sp. has the ability to synthesize glutathione phytochelatin (GSH) to respond to the toxic effects of heavy metals. If the micro algae cannot synthesize phytochelatin properly, the cells will die due to exposure to heavy metals in a long contact time. In this study, GSH was added to the metal biosorption process by micro algae Chlorella sp. This study aimed on determining the effect of the adding GSH during the biosorption process. The study was conducted with variations of GSH (0, 5, 10, and 15 mg/L) and variations of contact time (1, 2, 3, and 4 days). The results of this study show that high cell density occurred in the reactor with the addition of GSH 15 mg/L which is 1.72x106 cells/ml. The highest removal of Cr (VI) metal occurred in 4 day contact with the addition of GSH 15 mg/L and obtained a 72% removal efficiency.

“…Wahyu Irawati 1* dan Candra Yulius Tahya 2 Tembaga merupakan elemen atau material yang tidak dapat terdegradasi dan mudah untuk terakumulasi dalam tubuh makhluk hidup (Indirawati, 2017) serta mengendap pada sedimen selama bertahun-tahun (Khan et al, 2018). Tembaga konsentrasi berlebih dapat mencemari lingkungan dengan tingkat toksisitas yang sangat tinggi dan berbahaya bagi kehidupan organisme (Ratnawati, Ermawati, dan Naimah, 2010), khususnya pada ekosistem perairan. Hal ini karena air merupakan elemen esensial yang harus dilindungi agar kualitas dan kuantitasnya tetap dipertahankan untuk memenuhi kebutuhan hidup manusia ataupun makhluk hidup lainnya (Rosarina dan Laksanawati, 2019).…”

“…Metode pendekatan biologis dalam memanfaatkan potensi bakteri untuk menyisihkan tembaga dari lingkungan atau biasa disebut dengan bioremediasi merupakan metode pengolahan limbah yang lebih efektif, murah, dan efisien dibanding secara kimia (Aktas, 2013). Populasi bakteri yang hidup di perairan tercemar limbah tembaga akan mengembangkan kemampuan adaptasi untuk bertahan hidup melalui proses metabolisme sehingga dapat dimanfaatkan untuk proses bioremediasi (Ratnawati, Ermawati, dan Naimah, 2010).…”

The water quality of the Cisadane River, located in the industrial factory area, it is contaminated with copper, it is necessary to treat sewage. Biological wastewater treatment using bacteria is a more economical and effective method of removing copper from the environment than chemical methods. This study aims to isolate, identify, determine the level of resistance, and analyze the ability of bacteria to accumulate copper. Isolation was carried out by the spread method in Luria Bertani Agar medium containing CuSO4. Bacterial isolates were identified based on analysis of the 16S rDNA gene. The resistance level is determined based on the Minimum Inhibitory Concentration (MIC) value. The accumulation ability of copper was determined using an atomic absorption spectrophotometer. Six bacteria resistant to copper were isolated and identified as Pantoea agglomerans strain IrCis1, Klebsiella grimontii strain IrCis3, Klebsiella penumoniae strain IrCis4, Shigella flexneri strain IrCis5, Enterobacter cloacae strain IrCis6, and Enterobacter cloacae strain IrCis9 with MIC of 7 mM - 9 mM. Pantoea agglomerans strains IrCis1, Klebsiella grimontii strains IrCis3, Klebsiella pneumoniae strains IrCis4 can accumulate copper of 1,19 mg, 1,39 mg, and 0,92 mg, respectively, per gram of dry cell weight.

“…The use of disposable primary batteries can cause pollution to the environment due to the lack of means of treating waste from used batteries so that they end up in the trash (Widyaningsih & Mulud, 2017). One of the efforts to reduce this pollution is by making biobatteries (Ratnawati, et al, 2010). Bio-battery is a device that generates electrical energy from materials derived from living things.…”

The use of disposable primary batteries causes environmental pollution due to the lack of battery waste treatment facilities, so it is necessary to handle the problem by making bio-batteries from orange peel and tamarind. The purpose of this study is to know the influence of good electricity on variations of the combination of orange peel and tamarind. The novelty of this study is (1) the use of biomass combination of orange peel and tamarind as bio-battery electrolytes and (2) comparison of orange peel to tamarind. The method used in this study is by experimenting with a mixture of sweet orange peel and tamarind made into pasta and put in a used battery. The results showed that bio-batteries with a variation of 25% orange to tamarind had the highest voltage and the most powerful electric current. This happens because the ion content in the variation is not concentrated so it is easy to move widely. In conclusion, bio-batteries with a mixture of orange peel and acid are the best variation of 25% orange peel against tamarind. The study is expected to reduce the use of chemicals in batteries and reduce disposable battery waste.
