Oil palm frond pulp (OPF) was blended with activated carbon for the purpose of active packaging in this preliminary study. It was aimed to investigate the effect of in-situ activated carbon on physical and mechanical properties of the pulp handsheets made from OPF. Testing of property performances of the resulted handsheets included density, moisture content, thickness swelling, folding, tensile strength, %elongation, stiffness, and modulus of rupture. Ultimately, the intention is to use for prospected active packaging for fresh produce. OPF pulp was prepared by the kraft process. The pulp stock was mixed with different proportions of activated carbon (0, 10, 20, and 30% w/w). The results showed that an increased proportion of activated carbon decreased density and thickness selling, but had no effect on moisture content.

Oil palm shell activated carbon magnetic particle (CAC-MP) was prepared for adsorption of metal ions (Zn2+, Pb2+, Cu2+). Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), surface area and pore analysis (BET, BJH and t-plot method), field emission scanning electron microscopy (FESEM), vibrating sample magnetometer (VSM), and X-ray diffraction (XRD) were used to characterize CAC-MP. Its properties were compared with the parent activated carbon (CAC). The CAC-MP, with a high surface area (1007 m2/g), was used to study metal ions removal at different pH, adsorbent dosage, and contact time. The removal efficiency of metal ion increased with increasing pH, dosage, and time until equilibrium was reached. The optimum condition for maximum removal efficiency was at pH 6 and absorbent dosage of 0.5 g. Kinetic studies were also performed and the best kinetic model was fitted by pseudo-second-order model.

Oil palm tree can produce 22 oil palm frond / year, the average weight of frond per rod reaches 2.2 kg, so that each hectare can produce fresh frond about 9 tons / year or equivalent to 1.64 tons / year of dry matter. Activated carbon can be used as a good absorbent agent for gas purification process and removal of organic pollutants from water, such as in liquid waste. The objective of this paper is to know the different characteristics of activated carbon from oil palm frond (elaeis guineensis jacq) as raw material with variation of activator sodium carbonate (Na2CO3) and sodium chloride (NaCl). The activator concentration used is 10% each with an activation temperature of 600 ° C. The quality of activated carbons was analyzed by surface active carbon morphology and FTIR spectra analysis on activated carbon. The result of identification with FTIR spectrophotometer showed that the activated carbon in this study contained the functional groups of O-H, C = O, C = C, C-C, and C-H.
