Abstract

Phenols found in the wastewater of some industries have acute toxicity. The photocatalysis process can be used to degrade organic compounds such as phenols. To increase the photocatalytic activity of TiO2, a composite formation was formed between TiO2 and carbon nanotubes (CNT). Before being composited, CNT dispersion was carried out using cocoPAS surfactant as dispersing agent. The purpose of this study is to determine the effect of degradation temperature on phenol degradation. The process of making TiO2-CNT(cocoPAS) composites begins by dispersing CNT with cocoPAS surfactants and then composite with TiO2. Photocatalytic activity of the TiO2-CNT(cocoPAS) composite was tested at an initial phenol concentration of 30 ppm with variation of degradation temperature of 30,40 and 50ºC for 4 hours under UV light. Morphology of TiO2-CNT(cocoPAS) composites were characterized using SEM and phenol concentrations were characterized using a UV-Vis spectrophotometer. The highest degradation of phenols by TiO2-CNT(cocoPAS) composites at the initial phenol concentration of 30 ppm was at the degradation temperature of 50ºC, which was 35.59%.Keywords : photocatalysis, composite, TiO2, CNT, cocoPAS, phenol, temperature

Abstract

Waste from processed palm oil is increasing over time. Palm Oil Fuel Ash (POFA) from boilers can be used as a substitute for cement in concrete because it contains silica and alumina. This study examines the optimum mix of cement replacement by Palm Oil Fuel Ash (POFA) and silica fume addition to the concrete mixture. The variables used are the variation of silica fume addition (0-15%) with the control concrete is PCC concrete. The concrete will be tested for its compressive strength and porosity at the age of 7 and 28 days after curing in plain water. Based on the test result, the control concrete's compressive strength was 21,74 MPa. The highest compressive strength was the concrete mixture without POFA replacement with 15% silica fume addition, the compressive strength is 26,83 MPa. It proves the addition of silica fume in concrete increases the compressive strength. Keywords: Concrete, POFA, silica fume, compressive strength.

Abstract

The level of LPG demand is increasing every year, even the import of LPG has been carried out for a long time, but the need for LPG has not been fulfilled, this has led to the establishment of a Dimethyl Ether (DME) factory to cover LPG needs in Indonesia. DME can also be used as a propellant in aerosol form such as hairspray, insecticide, and air freshener. The main raw material used in the manufacture of DME is Oil Palm Empty Bunches (TKS). This factory is built with a capacity of 50,000 tons / year which will be established in Pelintung, Medang Kampai District, Dumai. The DME production process is carried out by the Indirect Synthesis process where DME is made through 2 processes, namely methanol synthesis from EFB and DME synthesis from methanol. Methanol synthesis and DME synthesis occur in 2 different reactors where methanol is first synthesized then dehydrated to DME. The main equipment design in this plant is the DME Distillation which functions to separate DME as the top product from Methanol and water as the basic product. The feed, distillate and bottom temperatures in this distillation tower are 48,10C, 33,70C and 231.40C with a pressure of 9 atm. , 97 m. Economic analysis on the design of this factory shows that this factory is feasible to be established with a factory Payback Period (PBP) of 2.29 years and a BEP at a capacity of 38%.  Keywords: Dimethyl ether, economic Analysis, empty palm fruit bunches
