Abstract

Catalytic naphtha reform (platformer) is the main process carried out in oil refineries to increase low octane naphtha into high octane gasoline. The Reformer will meet a wide range of products that require operating flexibility. Process optimization can be done by controlling using the ANFIS method. This optimization requires an accurate process model that is applicable in a wide range of operating conditions, therefore simplifications are made in the kinetic model modeling. This model provides three temperature profiles and concentrations of important hydrocarbons (naphthene, paraffin, and aromatic) throughout the reactor. The optimal control scheme using the ANFIS method is used to maximize the aromatic yield, following the reactor inlet temperature limit. The results obtained were compared with the aromatic results without control and using control with the neural network method. The results showed that the ANFIS method has the ability to control the process. Furthermore, the results obtained from the process are used to determine the pressure of the process during the reaction.

Abstract

One of the essential pieces of equipment at the Pertamina Refinery Unit V Balikpapan is the Furnace F-3-04 Vertical Cylindrical type. Furnace operation efficiently becomes very important given the vast energy consumption and directly influences the level of refinery profits. Therefore, it is necessary to do a simulation to increase the efficiency value to minimize energy use. This study aimed to determine the effect of O2 Excess and Flue Gas temperature on efficiency and to find the best efficiency from the simulation results on a Vertical Cylindrical Furnace. In this study, the furnace's efficiency is calculated and simulated using the indirect method. The heat entering the furnace is reduced by the heat lost compared to the heat entering. Initial data processing is a normality test to determine whether the data is usually distributed and can be used for data to be entered into the mathematical simulation of furnace efficiency. The efficiency value produced by Furnace F-3-04 is 86.3%, with an O2 excess value of 7.25% and a Flue Gas temperature of 419 0C. From the simulation carried out, it can be seen that the operating parameter that most affects efficiency is O2 Excess of 0.15 – 0.18% for every 0.5% decrease in O2 Excess for 5 simulations. Meanwhile, the Flue Gas temperature gets a value of 0.02 – 0.03% for every 2 0C decrease for 5 simulations. The best efficiency value is 87.7%, with O2 Excess of 4.75% and Flue Gas temperature of 409 0C.

Abstract

Kersen (Muntingia calabura L.) is a tropical plant from the Muntingiaceae family which is a wild plant that is often found in Indonesia. This plant is one of the herbal plants that are used as natural antioxidants. The purpose of this study was to obtain a drying model of cherry leaf extract and determine the activity of flavonoids as antioxidants in cherry leaf extract. The method used to obtain cherry leaf extract using ultrasonic sonication with a wavelength of 40 kHz. Variations made in the test are the length of drying time (30 minutes, 45 minutes, 60 minutes, 90 minutes, 120 minutes) and to find the most suitable drying model between Newton and Page. Concentration of cherry leaf extract using a rotary vacuum evaporator. Identification of cherry leaf extract, namely: determining the absorbance value for flavonoids and IC50 (Inhibitor Concentration) using UV-Vis Spectrophotometry and then determining the antioxidant content. The results of the study obtained that the highest wet extract yield was treated with a drying time of 30 minutes, which was 34.1%. The highest total flavonoid content was found in the 30 minute drying time treatment, which was 51,067 g/ml. The test of antioxidant levels obtained by IC50 is 0.89 ppm which is a strong antioxidant. The most suitable drying model is the Newton drying model with the equation MR=exp-(0.0029t) with a value of R2 = 0.9867 with k = 0.0029.

Abstract

Indonesia is the largest palm oil producing country in the world. In the palm oil production process, solid waste is produced, one of which is empty palm fruit bunches (EFB) of 25-26% w/w of the total palm oil raw material. OPEFB has several constituent components such as lignin, hemicellulose and cellulose. The high content of α-cellulose in OPEFB can be used as a base material for making nanocellulose. Nanocellulose was made in this study through delignification, ultrasonication and hydrothermal processes with the aim of obtaining the optimum ultrasonication temperature of nanocellulose. Temperature variations were carried out at 40, 50, 60 and 70 °C for 30 minutes. The results of the synthesis process can be seen visually for each temperature variation. Characterization analysis was performed using SEM (Scanning Electron Microscopy). The correlation between temperature variations (x) to the yield percentage of nanocellulose (y) follows the equation y = 7.921x + 7.345 and R2 = 0.9471. The optimum temperature of the ultrasonication process is 70 °C with a yield of 36.9%. The size of nanocellulose powder is 174.85-460.84 nm with SEM at 70 °C.

Abstract

Biodegradable plastic is an alternative environmentally friendly packaging material because it is made from renewable materials and is scientifically easily degraded by microorganisms and by weather. Renewable material that is abundant in Indonesia is cassava which has high potential as a raw material for making biodegradable plastics. Purpose This study was conducted to determine the process of making biodegradable plastic from cassava starch, knowing the effect of adding glycerol and chitosan to the mechanical properties of biodegradable plastics, and know the characteristics of biodegradable plastics from the best conditions. The process of making biodegradable plastic from cassava starch begins with mixing cassava starch with water and processing until starch dough is formed. Next, glycerol is added to the starch dough and mixed until homogeneous. The final stage is chitosan added to the mixture and stirred until well mixed. The mixture is then heated and molded according to the desired shape. Biodegradable plastics produced from a mixture of cassava starch, glycerol, and chitosan have good mechanical properties and can decompose naturally in the environment for the study variables with concentrations of glycerol 2%,4%,6%,8%,10% and chitosan 1%,3%,5%,7%,9% in a mixture of 100 ml. Mechanical tests such as tensile strength, percent elongation and biodegradation of biodegradable plastics are carried out on product characteristics. The result of this study was to obtain the highest tensile strength in sample 1 of 3.41 Mpa and had an elongation of 68%. While the highest elongation in sample 3 was 130% and tensile strength was 0.26 MPa. The highest biodegradation result in sample 1 was 31.70% and the lowest in sample 5 was 6.55%.

Abstract

Bananas, mangoes, and oranges are fruit commodities that are quite potent and have a promising export market share. The shelf life of the fruit is not long and causes physical-chemical damage to the fruit, one way that can be done in post-harvest handling of the fruit is by using the wax method. This study used types of wax, namely beeswax and rice bran wax. The purpose of this study was to determine the effect of beeswax coating on fruit weight loss, to determine the effect of rice bran wax concentration on the characteristics of rice bran wax coating and fruit weight loss, determine the effect of storage time of bananas, mangoes, and oranges on fruit weight loss. The independent variables in this study included rice bran wax concentration (6;9;12;15;18)% and fruit storage time of 3 weeks, while the dependent variables in this study included pH, density (gr/ml), viscosity (seconds), mango fruit weight loss ( %). The procedures in this study include the manufacture of beeswax coating, and rice bran coating, analysis of characteristics of beeswax coating and rice bran wax coating, and analysis of weight loss of bananas, mangoes and oranges after coating. The results of the analysis of the characteristics of rice bran wax coating (pH, density, viscosity) on the concentration of rice bran wax (6; 9; 12; 15; 18)% showed that the pH showed a downward trend with a pH value of 9.33; 9.22; 9.21; 9.18 and 8.95, the density showed a tendency to increase with a density value of 1.018; 1.021; 1.022; 1.023; and 1.026 gr/ml, the viscosity showed a tendency to increase with a value of 8.85; 8.2; 8.3; 8.43; 8.56 seconds. Characteristics of Beeswax Coating 12% resulted in a pH of 9.19, a density of 1.019 g/mL, and a viscosity of 8.3 seconds. The smallest weight loss of mangoes and oranges for 3 weeks was fruit coated with 12% beeswax coating, and the smallest weight loss for bananas for 3 weeks was fruit coated with 12% rice bran wax coating.
