Abstract

Waste water of textile industry contributes in environmental pollution, especially wastewater containing dye and organic compounds are dangerous because they are non-biodegradable, toxic and harmful to the environment, like as Rhodamine B. Therefore, it is necessary to do the processing of waste dye textile industry to reduce the impact of pollution on the environment. One of the lastest innovations in the processing of textile waste is using advanced oxidation processes (AOPs) by oxidant capable of generating a radical sulphate (SO4*). This study aims to determine the activity of Ce@Carbon Sphere as a catalyst in the oxidation process, to degradation of dye in wastewater by using a combination of peroxymonosulfate and catalyst Ce@Carbon Sphere as an oxidater, and determine the optimum conditions to reduce dye in water. Catalytic synthesis process carried out by the hydrothermal process to produce black carbon from D-glucose and Cerium Nitrate Hexahidrate solution, at 180oC for 18 hours in an autoclave. Then calcined with N2 at 550oC for 2 hours. Degradation of Rhodamine B (waste artificially) 25 ppm for 2 hours with various concentrations of the catalyst 0,1; 0,2; 0,3 and 0,4gr/L and the concentration proxymonosulfate 1; 2; 3 and 4 g/L. One oft the conditions for reducing the levels of Rhodamine B in water is concentration of peroxymonosulfate at 1 g/L and Ce@Carbon Sphere at 0,1 g/L with efficiency up to 32,59%.Keywords: AOPs, Rhodamine B, Ce@Carbon Sphere, Peroxymonosulfate

Abstract

Petroleum reserves in Indonesia are increasingly depleted, requiring the use of alternative energy that is environmentally friendly and renewable like biodiesel. Biodiesel can be made by transesterification process of vegetable oils. Process of making biodiesel commonly use homogeneous catalyst which has the disadvantage the formation of by products such as complexity of the separation of catalyst. Therefore, in this study biodiesel was synthesized from calophyllum inophyllum oil by using geopolymer catalyst. Geopolymer catalyst is first synthesized by reacting sodium silicate, metakaolin, NaOH, and water. Several variations of the process variables were done to assess its influence on yield of biodiesel. The variables were used consist of a dependent variables and independent variables. The dependent variables were calophyllum inophyllum oil weight of 50 grams, 3%-wt of catalyst concentration, reaction time of 120 minutes, and stirring speed of 400 rpm, while the independent variables which variation molar ratio of oil:methanol 1:6 and 1:9 and variations of temperature 55 and 65 oC. Physical characterization were done including density 871 kg/m3, kinematic viscosity 4.38 mm2/s, acid number 0.41 mg-KOH/g biodiesel and flash point 140°C respectively accordance with the standards of Indonesian biodiesel (SNI 7182:2015).Keywords: biodiesel, catalyst, calophyllum inophyllum oil, geopolymer, yield

Abstract

Response Surface Methodology (RSM) is a set of mathematical and statistical techniques that are useful for analyzing problems where several independent variables influence response. The ultimate goal of RSM is for optimizing response. The aim of this study to determine the optimal process conditions in the silica extraction process from POMFA by using Response Surface Methodology (RSM). Silica was extracted by reacting fly ash with NaOH and aquadest. The optimized variables were temperature of 120°C (low) and 150°C (high) and time of 4 hour (low) and 6 hour (high). The silica extract was precipitated using HCl 10% at temperature of 30°C; stirring speed of 500 rpm and pH 9. The silica gel was analyzed using XRF to determine chemical composition. The silica yield were calculated from the chemical composition obtained. RSM-CCD was applied to optimize the extraction process using software Minitab 16.1.1.Keywords: extraction, optimum, POMFA, RSM, silica

Biodiesel production from the vegetable oil using homogenous catalyst has disadvantage in the product separation and negative environmental impact. Biodiesel synthesis from off-grade palm oil using Na2O/Fly ash solid base catalyst is good to simplify the separation process and the utilization of fly ash as palm oil mill waste tp support the Na2O basic site. Biodiesel production aims in this study is to see the influence of reaction temperature, molar ratio of methanol and oil and concentration of Na2O/fly ash towards biodiesel yield. The process was conducted through reaction of esterification and followed by transesterification reaction.

Abstract

Catalyst cobalt nanomaterial (Co@NC) was prepared by MOF strategy using rhombic dodecahedral cobalt based on Zeolitic Imidazolate Framework -67 (ZIF-67) as an effective precursor and template. Co@NC was successfully synthesized by reacting cobalt (II) nitrate and 2-methylimidazole with methanol solvent at room temperature and allowed to stand for 48 hours at room temperature to form a purple solid. Then it is carbonized at 600oC for 6 hours with argon. Their properties were characterized by X-ray diffraction (XRD). The Catalyst Co@NC catalyst has 4 peaks that appear at an angle of 2θ: 44.24 °, 51.70 °, 71.03 °, 79.73 ° which are perfectly indexed to the metal characteristics of Co [JCPDS File No. 89-4307]. The catalyst activity of Co@NC was evaluated for the oxidation degradation of organic compounds in the pulp and paper industrial wastewater with radical sulfate. Effect of catalyst concentration (0; 0.1; 0.2; 0.3; 0,4 g/L) and reaction time 120 minutes was investigated in this study. The optimum conditions with the percentage of COD removal reached 80,92% obtained at 120 minutes, catalyst concentration 0.4 g/L, concentration of peroxymonosulfate 2 g/L, reaction temperature of 30oC. Therefore, the Co@NC nanomaterial is very feasible as a catalyst in industrial applications that will be used for wastewater treatment effectively. Keywords: AOP, COD, MOF, Nanomaterial, Wastewater
