“…In addition, the hydroxyl and carboxyl functional groups in the biosorbent become negatively charged due to deprotonization, so that the functional groups will be reactive in absorbing Hg 2+ ions. The interaction between Hg 2+ ions and biosorbent occurs due to the electrostatic force between the negative charge of the biosorbent which acts as an active site and the positive charge of metal ions [8].…”

Corn stalks are an agricultural waste that is commonly found in Indonesia. Corn stalks have a high enough cellulose content which has functional groups that can be used as biosorbents. This study aims to optimize the adsorption of corn stalk waste to mercury metal ions and then determine the adsorption capacity and adsorption constant of the Langmuir and Freundlich isotherm model. This research begins with corn stalk preparation, delignification, characterization using FTIR and SEM, determination of optimization of biosorbent weight, pH of Hg solution, contact time, and concentration of Hg solution, then applied to mercury metal contamination waste. Optimization of the weight of biosorbent in the range 0.4-1.2 grams, pH of the Hg solution is 2-4, contact time is 60-120 minutes, and concentration of the Hg solution of 30-100 g/L with a solution volume of 50 mL. Furthermore, determination of mercury levels, manufacture of standard series, and testing using ICP-OES. Followed by the determination of Langmuir and Freundlich's adsorption isothermal model. The results of this study indicate that the optimum conditions for the adsorption process occur at the weight of the biosorbent 1.2 grams, pH of the Hg 3 solution, contact time of 90 minutes, and concentration of Hg solution of 40 ppb with a solution volume of 50 mL. The application of biosorbent to metal contamination waste with adsorbed Hg concentration obtained 27.5772 ppb in 50 mL of waste solution with an adsorption efficiency of 88.44%. In the determination of Langmuir and Freundlich isotherms, a match was found for Langmuir adsorption isothermals with an adsorption capacity of 0.00333 mg Hg/g biosorbent and  = 176.8256.

“…Pemanfaatan serbuk eceng gondok teraktivasi sebagai adsorben logam kadmium (Cd) dengan metode kantung celup dilakukan oleh Azhari et al (2017) dengan waktu kontak 30 menit adsorben mampu menjerap logam Cd sebesar 57,175 mg/L atau sebesar 56, 441 % dengan konsentrasi larutan optimum 100 mg/L. Sedangkan Rakhmania, et al (2017), eceng gondok yang sudah diregenerasi menggunakan larutan HCl dan digunakan untuk adsorben dalam mengadsorpsi ion kalsium. Hasil penelitian menunjukkan bahwa waktu kontak optimum yang didapat adalah 40 menit dengan konsentrasi HCl 3 M. Dan dengan waktu dan konsentrasi tersebut, adsorben eceng gondok mampu menjerap ion kalsium sebesar 38.733 mg Ca/gr adsorben.…”

“…Selain itu, adsorben yang berasal dari tanaman eceng gondok mempunyai beberapa gugus fungsi aktif seperti karboksil dan juga hidroksil untuk menjerap ion kalsium (Ca 2+ ). Tidak hanya gugus fungsi hidroksil (OH) dan karboksil (COOH) yang dimiliki eceng gondok, tetapi juga gugus fungsi lain seperti amina (NH2)dan karbonil (COH) (Rakhmania et al, 2017).…”

Air sumur di Komplek PJKA RT 01 / RW 01 Dusun Tanjungsari Lemah Abang Cikarang Utara memiliki kesadahan yang tinggi. Kesadahan air sumur yang tinggi apabila dikonsumsi dapat membahayakan kesehatan manusia, terutama bagi fungsi ginjal sebagai organ ekskresi. Eceng gondok merupakan salah satu jenis tumbuhan air yang mempunyai kemampuan menyerap polutan pencemaran air, salah satunya adalah kesadahan air. Konsumsi air sadah dalam jangka waktu yang lama dapat menimbulkan gangguan fungsi ginjal. Penelitian ini bertujuan untuk mengetahui kefektifan adsorben eceng gondok teraktivasi HCl 3M dan NaOH 2% dengan variasi massa dalam menurunkan kadar kesadahan air sumur gali. Penelitian ini merupakan penelitian eksperimental dengan desain penelitian uji pendahuluan untuk mengetahui kadar kesadahan awal kemudian dikontakkan dengan serbuk eceng gondok teraktivasi. Hasil penelitian menunjukkan bahwa adsorben eceng gondok teraktivasi HCl 3 M dengan variasi dosis 0,5 g mampu mengapsorpsi kesadahan sebesar 11,15% dengan nilai kesadahan teradsorpsi sebesar 62,5 mg/L dan nilai kesadahan menjadi 498 mg/L. Sedangkan adsorben eceng gondok teraktivasi NaOH 2% dengan variasi dosis 0,1 g mampu mengapsorpsi kesadahan sebesar 34,5 mg/l atau dengan persen adsorpsi sebesar 6,16% dan nilai kesadahan menjadi 526 mg/L.

“…So far, water hyacinth (EichhorniaCrassipes) has only been considered a wild plant (weed) that grows a lot in areas of small rivers, lakes and swamps which may often be seen in residential areas (Herawati, 2013). This plant is a plant that has an extraordinary growth rate (water hyacinth growth expands and doubles through the formation of stolons), which ranges from 400-700 tonnes of biomass per ha per day (Rakhmania et al, 2017).…”
