“…Selama ini bagas tebu digunakan sebagai bahan bakar boiler di industri gula untuk memproduksi steam dan pembangkit listrik. Telah dilakukan penelitian pembuatan senyawa xanthate dari bagas tebu (Iryani et al, 2017) (Iryani et al, 2019). Sehingga akan dilakukan penelitian menggunakan bagas tebu sebagai bahan baku senyawa xanthate dengan variasi konsentrasi karbon disulfida (CS2) sebesar 120 − 160% dari berat sampel pada suhu xanthasi 35⁰C untuk memperoleh senyawa xanthate yang optimal.…”

Pencemaran logam berat merupakan salah satu masalah penting yang menimbulkan efek beracun. Logam berat yang terakumulasi pada tubuh manusia akan mengakibatkan berbagai resiko yang berbahaya. Mengingat bahaya yang ditimbulkan oleh logam berat, berbagai metode telah digunakan untuk menurunkan kadar logam berat. Salah satu metode yang digunakan dalam penelitian ini yaitu adsorpsi biosorben selulosa xanthate dari selulosa bagas tebu untuk menjerap logam berat Pb2+ dan Cu2+. Pembuatan biosorben dilakukan melalui proses xhantasi dengan memvariasikan konsentrasi Karbon Disulfida (CS2) yaitu 120%, 140%, dan 160% (b/b) dari jumlah bahan baku. Produk dari reaksi xhantasi selanjutnya dianalisa Derajat Substitusi (DS) dan Derajat Polimerisasi (DP) pada range 0,36−0,39 dan 301−308. Selain Uji Derajat Substitusi (DS) dan Derajat Polimerisasi (DP), karakter dari selulosa xanthate juga dilakukan analisa menggunakan SEM dan FTIR. Karakterisasi tersebut ditujukan untuk mengetahui morfologi permukaan dan perubahan gugus fungsi selulosa xanthate pada berbagai variasi konsentrasi karbon disulfida (CS2). Hasil pengujian menunjukkan bahwa karbon disulfida (CS2) tersubstitusi ke dalam gugus OH pada selulosa bagas tebu, sehingga selulosa xanthate mampu mengadsorpsi logam berat Pb2+ dan Cu2+ dengan kapasitas adsorpsi masing-masing 50,7 mg/g dan 47 mg/g pada konsentrasi Karbon Disulfida (CS2) 120%.

Manganese (Mn) is one of the most abundant metal in the soil. The presence of this metal is essentially needed by living things for the formation of cartilage and bone as well as driving various enzymes. However, in excessive amounts, the metal can cause disruption of the central nervous system. In this study, the removal of Mn was carried out by the adsorption process using zeolite adsorbent. Effects of contact time, pH of sample (2, 3, 4, 5, 6, 7, 8, and 9) and dosage of adsorbent (1; 1,5; 2; 2,5; 3; 3,5; 4; 4,5 and 5 g) were evaluated. The optimal conditions were obtained under operating conditions of 100 minutes contact time, 7 and 9 pH of the sample, and 5 g dosage of adsorbent. The adsorption process was able to reduce Mn metal up to 79.52%. The initial concentration of Mn sample was 5 g/L and the concentration of effluent after the adsorption process reduced to 1,024 g/L. The adsorption process resulted in a significant reduction of Mn level. However, the final result of the process shows the level of Mn that still exceeds the limit permitted by KEPMENKES No. 907/MENKES/SK/VII/2002 of 0.1 mg/L.

It has been known that some industrial liquid wastes usually contain a variety of heavy metals such as Cd (Cadmium), Pb (Lead), Ni (Nickel), Cr (Chromium), As (Arsenic), Cu (Copper), and Fe (Iron). If these liquid wastes are not managed properly, it will damage the water environment, especially the water body like rivers and lakes. Various methods have been applied to remove heavy metals from these liquid wastes, such as precipitation, ion exchange, membrane processes, adsorption, coagulation, and flotation. One common method that can be applied to manage waste that contain heavy metals is an adsorption method. Recently, it has been a trend to use biomass based adsorbent or usually called by bio-adsorbent. In this research bio-adsorbent has been prepared from cassava stem pith powder. This research was conducted to study the capability of bio-adsorbent made of cassava stem pith powder to adsorb Pb2 + metal ions. Several variables have been used during the adsorption test, which are pH condition (3, 4, 5), adsorption time (10, 20, 50, 120 mins), and initial concentrations (5, 10, 20 mg/L). The adsorption process involving functional groups contained in the adsorbent so that there will be interactions between the adsorbents with Pb2+ metal ions. The sample characterization was carried out using an Atomic Absorption Spectroscopy (AAS) apparatus. The adsorption test results showed that the optimum conditions for Pb2+ adsorption by the bio-adsorbent occured at pH = 3, adsorption time of 120 minutes, and initial concentration of 5 mg/L, in which the capacity was about 2.525 mg/g with the percent removal (R%) of 88.88%.
