The reused of cooking oil had been widely found in Indonesia whereas it is dangerous for health due to its carcinogenic properties. Purification of used cooking oil had been extensively investigated using various methods such as adsorption. Carbon-based materials are the common adsorbent cause having large capability to adsorb organic and inorganic compound. Activating the carbon surface affected the higher pores and adsorption potential. Recently, some raw organic materials are converted to activated carbon. In this investigation, we transformed Jatrhopa curcas L leaves to activated carbon for purification the used cooking oil. The resulting of the purification of used cooking oil were investigated based on the free fatty acid and peroxide value under adsorbent optimum condition.

Polystyrene (PS) is one form of the plastic that is most widely utilized for household application. However, plastics made from PS can pollute the environment. Hence, it is necessary to modify PS by mixing it with a biodegradable polymer like poly (ɛ-caprolactone) (PCL). The focus of this research was to determine the mechanical and thermal properties of PS/PCL polyblends. In this research, polyblend are prepared by mixing PS with PCL that acquired using the bis(dibenzoylmethanato)zirconium(IV) chloride bis(dibzm)2Zr catalyst. The method employed is solvent casting with a ratio of PS/PCL of 10/0, 10/1, 10/2, 10/3, and 10/4 (w/w). The optimum mechanical properties were obtained in 10/2 mixing which had a tensile strength of 6.72 MPa with 1.01% in elongation. Furthermore, the optimum PS/PCL polyblend was also characterized using DSC to determine its thermal properties.

Molecularly Imprinted Polymer (MIP) membranes as cholesterol absorbers have been successfully synthesized. MIP membranes can absorb cholesterol molecules because they have cavite (pores) and active groups that are selective and sensitive to cholesterol molecules. MIP membranes are synthesized from butyl acrylate monomers, cross-linkers, ethylene glycol dimethacrilate (EGDMA), initiators of 2- 2-dimethoxy-2-phenylacetophenone (DMPP, sodium dodecyl sulfate (SDS) as surfactants, and cholesterol as templates. MIP membranes are synthesized using photopolymerization irradiated with UV light. The results obtained in the form of powder solids can be characterized using UV-Vis spectrophotometry. The results obtained by UV-Vis spectrophotometry showed that the MIP membrane prepared a standard curve with a linear regression equation y = 0.0054x-0.007 with a value of R2 = 0.9982. This suggests that MIP membranes are selective and sensitive to analytes. At optimum absorption of the MIP-cholesterol membrane can absorb cholesterol molecules in the amount of 0.020 grams of cholesterol composition within 20 minutes

The fatty alcohols C8, C10, C16 and C18 were used as raw materials for the sulfation reaction using the SO3-DMF complex to study the ratio of carbon chains. The first step is to prepare the SO3-DMF complex, by reacting SO3 gas into DMF at a temperature of 0-4 0C with a reaction time of 3 hours, then sulfation is carried out at 100 0C for 5 hours on C8, C10, C16 and C18. Tests were carried out on the results of sulfation with an FT-IR Spectrophotometer. Surface tension, foam stability and yield calculations. From the sulfation results, the yield results were respectively 83%, 81%, 68% and 61% then the results from the surface tension analysis were 35.3, dyne/cm, 30.3 dyne/cm, 29.4 dyne/cm and 33.6 dyne/cm and foam stability analysis of 0.2 cm, 0.8 cm, 0.7 cm and 1 cm. Based on the surface tension reduction value, palmityl alcohol is the best raw material for making surfactants.

Fe deficiency in plants results in yellowing of leaves on plants and also reduces the quality of fruit produced. Fe deficiency in plants can be treated by applying slow release fertilizer which will release the nutrients in the fertilizer slowly according to plant needs so that there will be no problem of deficiency or excess of Fe. Activated Carbon/Alginate/Nanocellulose-Fe Composite can be used as slow release fertilizer because this composite releases Fe slowly with citric acid medium and tested with AAS. The functional groups in the Activated Carbon/Alginate/Nanocellulose-Fe Composite showed no disappearance of the functional groups belonging to activated carbon, alginate or nanocellulose so that it can be said that these three components were successfully made into composites and can be carriers of nutrients in micro-fertilizers.

The sulfation reaction between myristyl alcohol and the SO3-DMF complex has been successfully carried out to produce sodium myristyl sulfate. Formation of the SO3-DMF complex by reacting DMF and SO3 gas obtained from the reaction of phosphorus pentaoxide and H2SO4. The variables studied were the time of formation of the complex, the time and temperature of sulfation and the concentration of NaOH at neutralization. The results of myristyl alcohol sulfation with SO3-DMF were tested by FTIR spectroscopic analysis, surface tension test, and foam stability test. The formation time of the SO3- DMF complex of 5 hours is the result of the highest surface tension reduction and the most optimal foam stability. The results of the foam stability test analysis showed the highest value at 80oC with a foam stability of 0.5 cm. The best result of sulfation neutralized with 40% NaOH solution was able to reduce the surface tension value and has foam stability up to 66% with a decrease in foam height of 0.3 cm

This study aims to determine the adsorption capacity, study the kinetics and adsorption equilibrium of activated carbon/AC and composite carbon/AC-Cu(TAC) in the adsorption process of Fe metal. Oil palm empty fruit bunches (EFB) were used as activated carbon and modified with MOFs Cu(TAC) composite. The concentration of Fe(II) ions adsorbed during the adsorption process was analyzed using AAS. The variations used to determine the optimum conditions for absorption of Fe(II) ions are the mass variation of the adsorbent, the variation of the adsorbate concentration and the contact time between the adsorbent and the adsorbate. Through variations in concentration, the adsorption isotherm characteristics were determined and through variations in contact time, the adsorption kinetics model was determined. The results of AC characterization showed a sharp absorption in the presence of OH, CH and CO groups which indicated the presence of cellulose. AC is amorphous and AC-Cu(TAC) is crystalline and the pore size is mesoporous. The optimum condition for AC is the mass variation of 1 g with an absorption capacity of 0.1816 mg/g, a variation of the concentration of 60 ppm with an absorption capacity of 3.49 mg/g and a contact time of 75 minutes with an absorption capacity of 3.82 mg/g. The optimum condition for ACCu(TAC) was the mass variation of 1 g with an absorption capacity of 0.7275 mg/g, a variation of the concentration of 180 ppm with an absorption capacity of 10.52 mg/g and a contact time of 15 minutes with an absorption capacity of 10.85 mg/g.

本研究旨在确定活性炭/AC和复合碳/AC- cu (TAC)在吸附铁金属过程中的吸附能力，研究其吸附动力学和吸附平衡。以油棕空果束(EFB)为活性炭，用MOFs - Cu(TAC)复合材料进行改性。采用原子吸收光谱法分析了吸附过程中吸附的铁离子浓度。确定Fe(II)离子吸附最佳条件的变量是吸附剂的质量变化、吸附质浓度变化和吸附剂与吸附质的接触时间变化。通过浓度变化确定了吸附等温线特征，通过接触时间变化确定了吸附动力学模型。AC表征结果表明，在OH、CH和CO基团存在的情况下，活性炭有明显的吸收，表明纤维素的存在。AC为无定形，AC- cu (TAC)为结晶，孔径为介孔。最佳条件为:质量变化1 g，吸收容量为0.1816 mg/g;浓度变化60 ppm，吸收容量为3.49 mg/g;接触时间为75 min，吸收容量为3.82 mg/g。ACCu(TAC)的最佳条件为:质量变化1 g，吸收容量为0.7275 mg/g;浓度变化180 ppm，吸收容量为10.52 mg/g;接触时间为15 min，吸收容量为10.85 mg/g。AC-Cu(TAC)对Fe(II)离子具有较好的吸附能力。对于AC和AC- cu (TAC)，适宜的吸附等温线为Freundlich等温线，适宜的吸附动力学模型为拟二级

Oil palm empty fruit bunches (EFB) were used as activated carbon and modified with MOFs Cu(TAC) composite. The concentration of Fe(II) ions adsorbed during the adsorption process was analyzed using AAS. The variations used to determine the optimum conditions for absorption of Fe(II) ions are the mass variation of the adsorbent, the variation of the adsorbate concentration and the contact time between the adsorbent and the adsorbate. Through variations in concentration, the adsorption isotherm characteristics were determined and through variations in contact time, the adsorption kinetics model was determined. The results of AC characterization showed a sharp absorption in the presence of OH, CH and CO groups which indicated the presence of cellulose. AC is amorphous and AC-Cu(TAC) is crystalline and the pore size is mesoporous. The optimum condition for AC is the mass variation of 1 g with an absorption capacity of 0.1816 mg/g, a variation of the concentration of 60 ppm with an absorption capacity of 3.49 mg/g and a contact time of 75 minutes with an absorption capacity of 3.82 mg/g.
