The study aims to find out about the possibility of utilizing cassava peel waste as raw material for making activated carbon to reduce levels of Manganese in water. This study also wants to see the effect of variations in the concentration of activated carbon from cassava peels on decreasing levels of Manganese in water. This research was conducted at the Laboratory of the Akademi Analis Kesehatan Pemerintah Aceh and at the UPTD Laboratorium Kesehatan Banda Aceh on 3-11 March 2016. Manganese was analysed using the persulfate method while the Manganese was examinated by the spectrophotometric method. The sample used is an artificial sample by adding MnSO4 to water. The variation of activated carbon concentration added is 2 gr, 3 gr, and 4 gr. The results are that with the addition of 2 grams of activated carbon the percentage of Manganese reduction was 70.37%, the addition of 3 grams of activated carbon decreased Manganese concentration by 86.59%, while the addition of 4 grams of activated carbon reduced the percentage of Manganese to 92.33%. It can be concluded that the higher the concentration of activated carbon added, the higher the decrease in levels of Manganese in the water.

H3po4 Activation

In this study, the activated carbon produced from mango kernels and corn cobs by impregnating the hydrothermally treated raw materials with 85% H3PO4 were characterize for their physical surface morphology and types of surface functional groups using SEM and FT-ir, respectively. Six samples of activated carbon were submerged for 1 hour, the second sample for 2 hours, and the third sample for 3 hours. SEM results showed that both KAC (Kernel Activated Carbon) and CAC (Corn Activated Carbon) had increasing roughness and irregularity along with residence time of the samples. Results from FT-ir (Fourier-transform infrared spectroscopy) testing of the mango kernels samples showed that a C-O stretch, C-H, C=O stretch, and C-N stretch on the surface. While corncobs consist of C-H bend, and O-H bend for the 1-HR sample. The 2-HR and 3-HR samples consist of C-O stretch, C-H wag, C-N stretch. Analysis of the relationship between residence time and adsorptive capacity was done using AAS via batch adsorption in a tri-metal solution of Cu(Copper), Ni(Nickel), and Pb(Lead) with results that showed CAC and KAC, with soaking time of 3 hours is a good adsorbent of Copper and Nickel, while soaking time of 2 hours yields the best adsorption conditions for both CAC and KAC.
