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

Pineapple leaf waste can be utilized as a raw material for synthesis of bioplastic. the objective from this research was to determine effect of comparison of chitosan and cellulose from pineapple leaf fiber in synthesis of bioplastic and also to determine the good composition of comparison who based on mechanical properties of bioplastic. This research began by extracting cellulose from pineapple leaf fiber in three stages. The first stage was alkaline treatment (delignification), pineapple leaf fiber were cut in size ± 5 mm. Then 400 ml of 1M NaOH was added in 40 grams of fiber and heated at 80°C for 4 hours then washed and filtered. The second stage was bleaching, result of delignification process was dissolved in 5% NaOCl for 3 hours at 30°C then filtered. The third stage of acid treatment, the results of bleaching added 3% HCl and heated at 60°C for 1 hour then filtered and dried so that cellulose was obtained. Furthermore, synthesis of bioplastics was made by mixing PVA 10%, cellulose 1 gram and chitosan with comparison of chitosan: cellulose was 4:10; 5:10; 6:10. Then bioplastic mixture heated and stirred at 70°C for 20 minutes then printed on the glass mold. Repeat the synthesis for cellulose 2 gram. The good composition results in this study were chitosan with a ratio of 5:10, cellulose 2 grams and PVA 10%. Where the results of the tensile strength, elongation, biodegradation and water uptake produced were 15.36 MPa, 10%, 28.44% for 2 weeks and 82.17% respectively. The results of the analysis of Scanning Electron Microscopy (SEM) bioplastics showed that the surface of the bioplastic looks homogeneous and by using the ImageJ application the average of cellulose particle size was 0.246 µm. Keywords: bioplastic, cellulose, chitosan, pineapple leaf fiber, pineapple leaf waste.

Abstract

Pineapple leaf fiber consists of about 70-80% wt cellulose giving its high tensile strength and elastic modulus for bioplastics. To increased the elongation of bioplastic, starch has to be mixed with other synthetic polymers such as polyvinyl alcohol (PVA). The aimed of this research was to determine the effect of various pineapple leaf fiber and polyvinyl alcohol (PVA) concentration to the mechanical properties (tensile strength, elongation, modulus young and tear strength), water uptake, biodegradation and morphology. Bioplastics were made by mixing of starch of jackfruit seed, water, filler and plasticizer with variation of fiber were 0 (%w/w), 2 (%w/w), 4 (%w/w), 6 (%w/w), 8 (%w/w), and 10 (%w/w) and ratios starch: polyvinyl alcohol (PVA) were 1:1 and 1:1,5. The results revealed that the filler fiber and PVA gave an impact to mechanical properties of bioplastic, the best mechanical properties was on bioplastic with composition starch:PVA 1:1 and filler 8 (%w/w) with tensile strength 15,79 MPa, and modulus young 1967,01 MPa and tear strength 3,4021 Kgf. The best water uptake of bioplastic is 32,5 % and the fastest degradation time on bioplastic with composition fiber 10 (%w/w) and ratio starch:PVA 1:1,5 in 7 days. SEM analysis showed that filler distribution was not spreading evenly on matrices. Keywords: jackfruit seed, bioplastic, starch, polyvinyl alcohol, pineapple leaf fiber

Abstract

Transesterification reaction is a reaction between oils (triglycerides) with alcohol to produce fatty acid alkyl esters and glycerol as a byproduct. Biodiesel is obtained by reacting vegetable oils or fats with methanol. So that the resulting product is known as the methyl ester. Due to, production of petroleum fuels is limited, it is necessary to develop a vegetable oil to produce biodiesel. One of the vegetable oil that can be used is derived from CPO (Crude Palm Oil) by using a column centrifugal contactor. In this study, biodiesel obtained by transesterification of CPO (Crude Palm Oil), using KOH catalyst. The process is conducted by variation of temperature (50ºC., 60°C, and 70ºC), and reaction time (0.5, 1 and 1.5 hours), with a fixed variable stirring speed of 300 rpm and a molar ratio of methanol / oil 6: 1, the concentration of catalyst KOH 1%wt. Based on the test results showed that the transesterification reaction time and temperature affected by the speed of reaction formation of biodiesel. The good operating conditions obtained in this study at temperature of 60°C, and the reaction time of 1.5 hours which resulted in the conversion reaction of 39,47%. The percentage of ester product area is 6.37% and 28,894% glycerol. Methyl ester product was obtained in the form of palmitate, dimethyl azelate, methyl myristate, methyl laurate, and methyl nonanoat.

Abstract

Along with the development of the era, the need for fuel oil is increasing. The development of research and the use of diesel motors in industry will not stop just because of the depletion of fossil fuels. The search for alternative fuels as a substitute for diesel continues to be carried out in addition to dealing with the problems of the global energy and environmental crisis as well as helping to develop automotive technology as a work of human culture. Methyl ester is a biofuel that can be used to power diesel engines. The availability of fuel oil derived from petroleum is running low and the price is increasing so that alternative fuel sources are needed. One of the substitutes for conventional fuels from petroleum is vegetable oil. Methyl ester is produced using a transesterification reaction by changing the triglycerides which are reacted with one of the alcohol compounds, namely methanol to become methyl ester, and a production capacity of 250,000 tons / year is obtained. The main design tool is the CSTR (Continuous Flow Stirred-Tank Reactor) reactor which is used as a place for the transesterification reaction between triglycerides and methanol to produce methyl ester (main product) and glycerol (by-product). The operating temperature used is 333.15K. Based on the calculation results, the reactor volume is 57.28 m3, the reactor diameter (OD) is 168 in m with torispherical flanged and dished head and skirt support. Keywords: Methyl ester, reactor, transesterification, triglycerides.

Abstract

Palm oil mill effluent continues to grow along with palm oil production in Indonesia. Palm oil mill effluent treatment has been using anaerobic ponds which are not efficient due to the require large areas of land and due to greenhouse gases because they produce CO2. Electrocoagulation is an alternative technology and advanced technology in treating palm oil mill effluent. Electrocoagulation is a method of coagulation using direct current through the electrochemical process. This research discusses the variation of voltage and flow rate using reactor methods with pollutant parameters such as biological chemical demand, chemical oxygen demand, total suspended solids and acidity (pH). The type of electrodes used is aluminum with voltage variations of 5, 7 and 9 volts and flow rate variations of 3,36; 4,32; and 7,5 L/hour. The sample used came from PTPN V Sei Galuh in Riau. The results obtained by the highest percentage of reduction in BOD were 84.76%; COD of 83.38%; TSS of 88.73% at a voltage of 9 volts and a flow rate of 3,36 L/hour. The results of this research are in accordance with the standard quality standards for palm oil mill effluent in the Minister of Environment Regulation number 5 of 2014. Keywords: BOD, COD, electrocoagulation, TSS, pH.
