Abstract

Abstract Congeal in the pipeline is one of the biggest problems faced by PT.SPR Langgak in piping crude oil from production wells to oil processing unit caused by decreasing oil temperature. The purpose of this study is to study the effect of environmental temperature on fluid temperature in the pipeline, study the effect of wind speed on fluid temperature in the pipeline and to determine the location of the occurrence of congeal in PT.SPR Langgak pipeline. Determining the location of the occurrence of congeal using the model T with analytical methods in the Matlab software is by entering parameters of pipe temperature, viscosity, density, fluid velocity, wind speed and environmental temperature. The congeal location was determined by model T obtained in the Zone C pipeline distance 44.9-449m with the average error model T is 1.88%. This model T can be applied provided the paraffin content is 15-60% and the pipe characteristics (pipe thickness, pipe diameter and pipe material) are the same.

Abstract

The synthesis of biodiesel is affected by several factors, one of them is the mole ratio of oil to methanol. Producing biodiesel need excess amount of methanol to increase biodiesel yield. The effect of mole ratio of oil to methanol of 1:9; 1:12; 1:18 and the amount of La impregted to ZnO of 1%; 2%; 3%; 6% to the biodiesel yield were studied. The impregnation of La into ZnO was done by maxing La2O3 and ZnO, and then the calcination process was applied for 6 hours at 500 oC using N2 gas. The oxidation process was done for 2 hours at 400 oC using O2 gas. The reduction process was done for 2 hours at 400oC using H2 gas in order to reduce oxygen in La2O3. The esterfication process was done in 1000 cm3 stirred glass reactor, the operating conditions were temperature of 60 oC and time of 60 minutes. After that, the transesterification process was done using the same equipment. The operating conditions were temperature of 60 oC and time of 90 minutes, stirring speed of 400 RPM, and amount of catalyst was 1% (w/w) oil. The highest biodiesel yield of 90.937 % was obtained at the mole ratio of oil to methanol 1:18 and amount of La impregted into ZnO of 6 %. Physical characteristic of biodiesel obtained were density of 881 kg/m3, kinematic viscosity of 3.53 mm2/s, acid number of 0.423 mg-KOH/g biodiesel and flash point of 148 oC which is in accordance to the standard of Indonesian Biodiesel (SNI 04-7128-2015).Keywords: biodiesel, CPO, La/ZnO catalyst, transesterification

Abstract

Textile industries in Indonesia have been growing year by year and have an important role in economic system. However, their enhancement raises environmental pollution because of their dye wastes. Either small-scale or large-scale contamination have massively spoiled some rivers in Indonesia, such as Ciliwung, Cisadane, and Bengawan Solo. Therefore, a special method like photocatalytic is highly needed to handle it. Photocatalytic method is able to degrade dyes quickly by producing hydroxyl radical (•OH) as a strong oxidant. One of the best photocatalysts to use is covalent triazine framework (CTF) with copper (Cu) as catalyst doping synthesized by using an ionothermal method. Photocatalytic degradation of methylene blue reached the highest degradation performance 95,02%. Keywords: textile, photocatalytic, hydroxyl radical, covalent triazine framework, ionothermal

Abstract

This study examined the compressive strength and porosity of PCC concrete and POFA concrete with the addition of silica fume soaked in peat water. POFA is used as a cement substitute with variations of 0% and 20% and the addition of silica fume is 10%. The design compressive strength is 20 MPa. Treatment of the specimens was carried out in normal water for 28 days and then immersed in peat water for 0, 7 and 28 days. The results of testing the compressive strength of concrete at 28 days of immersion in peat have increased 16.73% with 29.24 MPa in PCC concrete, 29.49% with 32.69 MPa in POFA 0% concrete and 17.58% with 25.77 MPa in POFA 20% concrete. The porosity value of PCC concrete at 28 days of peat decreased by 6.55%. A decrease in porosity values also occurred in POFA 0% concrete and POFA 20% concrete by 20% and 26.78% at 28 days of peat. Based on the test results, it can be concluded that replacing cement with POFA and adding silica fume to concrete has a positive impact on the compressive strength and porosity of concrete in peat water. Key words: Compressive strength, porosity, POFA, silica fume, peat water

Abstract

The decline in fossil fuel sources has prompted research into finding renewable fuels. One of environmentally friendly energy sources with high efficiency is by producing liquid oil from palm oil empty fruit bunch (EFB) and coal. Pre-treatment of empty fruit bunches using NaOH and various concentrations of H2O2, various ratios of EFB/coal, the ratio of CaO catalyst, chemical and physical characteristics were studied to produce the better liquid oil yield. The H2O2 concentrations are 0%, 1%, 2%, and 3%. The ratios of EFB/coal (R) are 0/100, 25/75, 50/50, and 75/25. The ratios of catalyst CaO/raw material are 0%, 3%, 6%, and 9%. It ran at 400 °C with 100 mL/min nitrogen gas flowing during one hour. The results showed that adding sodium hydroxide and hydrogen peroxide in the EFB pre-treatment increased the liquid oil yield. With an increase in the EFB/coal ratio, the liquid oil yield increased. Co-pyrolysis treated EFB and Coal with a ratio of 75:25 produced 32% liquid oil yield, but the liquid oil yield decreased to 19% with the addition of 9% CaO catalyst. However, the addition of CaO catalyst reduces the acidity and increases the calorific value of the liquid oil.

Abstract

Trichoderma asperellum LBKURCC1 adalah galur Trichoderma yang diisolasi dari tanah perkebunan cokelat di Riau yang mampu memproduksi lakase. Lakase merupakan enzim ligninolitik yang dapat mendegradasi lignin, sekaligus mengoksidasi senyawa fenol. Penelitian ini bertujuan mengoptimasi produksi lakase T. asperellum LBKURCC1 secara fermentasi padat (SSF) menggunakan batang padi sebagai penginduksi lakase, di dalam reaktor labu sederhana. Optimasi parameter fermentasi (waktu fermentasi, kadar air dan konsentrasi Cu2+)dilakukan menggunakan Central Composite Design (CCD) dengan Response Surface Methodology  (RSM). Hasil ANOVA menunjukkan bahwa model quadratik dipilih, dengan persamaan regresi Y= 64,19 - 6,71 X1 + 6,93 X2 - 15,65 X1*X1 - 7,11 X2*X2 - 15,40 X3*X3. Waktu fermentasi, kadar air dan konsentrasi Cu2+ sebagai CuSO4.7H2O ditemukan memiliki efek signifikan (p-value<0,05) terhadap aktivitas lakase yang diproduksi. Kondisi optimal untuk produksi lakase dengan penginduksi batang padi, secara SSF dalam reaktor labu, adalah 7 hari fermentasi, kadar air 67% dan konsentrasi CuSO4.7H2O 0,046 g/L. Aktivitas lakase yang diperoleh pada kondisi optimum adalah 65,3±0,7 mU per gram batang padi. Meskipun hanya meningkatkan aktivitas lakase 2% dari aktivitas pada center point, kondisi optimum tetap membuat proses menjadi lebih ekonomis dan efisien, karena memperpendek waktu produksi dari 8 hari menjadi 7 hari, dan mengurangi konsentrasi penambahan Cu2+.

Abstract

Aromatic compounds in industrial wastewater such as phenols can contribute as pollutants which are highly toxic and carcinogenic. Phenol degradation can be carried out by a photocatalytic process which can convert phenol into non-toxic and enviromentally friendly compounds. The performance of titania (TiO2) photocatalyst was enhanced by using carbon nanotube as a doping agent for titania. To reduce carbon nanotube agglomeration, the surface of carbon nanotube was modified with cocoPAS surfactant. The purpose of this study was to synthesize titania-carbon nanotube-cocoPAS composite and evaluated the effect of initial phenol concentration (10, 20, 30 ppm) on the phenol photodegradation effectivity using titania-carbon nanotube-cocoPAS composite. Titania-carbon nanotube-cocoPAS composite synthesis was carried out by forming a composite between TiO2 and carbon nanotube that had been modified by surfactant. Composite were characterized by SEM, FTIR, and XRD. Phenol photodegradation was carried out at a degradation temperature of 50ºC for 4 hours under UV light. Samples were drawn at regular intervals and residual concentration of phenol in each sample was analysed using UV-Visible spechtrophotometer. The highest degradation effectivity in 4 hours was 81% at initial phenol concentration of 10 ppm.

Abstract

One of the latest innovations in textile waste treatment is advanced oxidation processes (AOPs) methods using an oxidizing agent capable of producing sulfate radicals (SO4•). This study aims to determine the activity of the Mn/Carbon sphere catalyst in the oxidation process, reduce the dye content by using a combination of peroxymonosulfate (PMS) and Mn/Carbon sphere catalyst as an oxidizing agent, and determine the optimum conditions in the process of reducing dye levels in the water. A hydrothermal process carried out the catalyst synthesis process to produce black carbon from D-glucose solution, then impregnated with variations of 3% and 5% of Mn metal. The degradation of methylene blue (artificial waste) of 25mg/L (1:10 dilution) was carried out for 120 minutes with variations in the catalyst mass of 0.001, 0.002, 0.003, and 0.004g and the mass of PMS 0.01, 0.02, 0.03, and 0, 04g in 100ml sample. Mn/Carbon sphere catalyst was able to activate PMS and was able to degrade methylene blue by 88.16%. The optimum condition for reducing the methylene blue levels in the water is at a concentration of 1g/L PMS and a Mn/Carbon sphere catalyst (5% Mn metal) 0.5g/L with an efficiency of 88.16%.

Abstract

The current consumption of fuel oil, especially gasoline and diesel oil, is increasing. Along with the decline in production, national oil production activities encourage efforts to find alternative fuels as a substitute for oil-based energy supplies. Bio-oil is an environmentally friendly alternative fuel for diesel that can be used as fuel. In this study, the raw materials were palm oil empty bunches and polypropylene plastic waste. The purpose of this study was to determine the effect of the ratio of raw material for oil palm empty fruit bunches and polypropylene, the effect of co-pyrolysis temperature on the yield of bio-oil and determine the characteristics of the resulting bio-oil. This study used the variable ratio of oil palm empty fruit bunches and polypropylene (100:0, 80:20, 70:30 and 60:40) and co-pyrolysis temperature (400, 450, 500 and 550 °C). The results showed that the highest yield of bio-oil was obtained, namely 41.6% with a ratio of EFB: PP (80:20) at temperature of 450 °C. The characterization of the product obtained was density of 0.891 g/ml,  viscosity of 4.18 cSt,  pH of 3.38 and  calorific value of 43.2 MJ/kg.
