Abstract

Coal fly ash could harm environment and dangerous for human health. Coal fly ash could be used as silica precursor because it contains silica in considerable amount. Method that used to isolate silica is alkaline fusion which used NaOH. The goals are to determine the effect of precursor and solvent ratio (1:9; 1:16; 1:23) and ageing time (3, 6, and 9 days) to particle size and characteristic obtain. Procedure of separating silica begin from burnt fly ash at 750°C, dissolved in HCl, filtered the solution to obtain the precipitate, dried the precipitate and dissolved in NaOH to obtained Na2SiO3. Procedure of nanosilica synthesis was carried out with mixed methanol, water, ammonia, and precursor while stirred for 8 hours, ageing for few days, followed with separate solution using centrifugation method. Product obtained was then characterized using SEM-EDS and XRD. From the results obtained, the ratio of precursor and solvent concentration would affect the particle size obtained and the amount of the product. The highest amount of Si obtained when ratio of precursor : methanol = 1:23 and ageing time 9 days which is 22.64%. Meanwhile, ageing time would affect the particle size distribution obtained. The product also known has amorphous structure.

Abstract

Used cooking oil is oil that come from oil frying foodstuffs.  The difference of used cooking oil with new vegetable oil lies in the composition of new saturated fatty acids and unsaturated. Used cooking oil has saturated fatty acid that is greater than new vegetable oil. As a result Used cooking oil is very dangerous when consumed and when discharged into the environment and will pollute the around environment. Therefore Used cooking oil is suitable to be used for biodiesel feedstock. Utilization of Used cooking oil as raw material for biodiesel is one of the ways to reduce waste that produce economic value and creating an alternative fuel for diesel fuel substitute. Used cooking oil can be processed into biodiesel by transesterification with methanol using zeolite sulfated zirconia catalyst. Used cooking oil containing free fatty acids of 1,64% and a density of 0,911 g / ml Transesterification of Used cooking oil with sulfated zirconia zeolit catalyst was conducted in a batch reactor with maximum volume of 1000 mL equipped with a heater, thermometer, stirrer, and tap of the sample taker. Variables which were studied in this research include the ratio of methanol to oil (1:4, 1:6, 1:9, 1:12), reaction temperature (100OC, 110OC, 120OC ), and concentration of catalyst (0,5%, 1%, 2%).  Condition process that was optimum was achieved at the ratio of oil to methanol 1:6, 2% catalyst concentration, reaction temperature of 120oC,  and reaction time for 120 minutes with a conversion of 71.62%.

Abstract

Sunan Hazelnut is one plant that thrives in Indonesia and  have high productivity is 50-300 kg per tree per year, with oil content of 45-55%, so it very potential to be used as raw material for biodiesel production. Sunan Hazelnut oil can not be converted directly into biodiesel because the free fatty acid (FFA) content is high. To overcome this problem, a two-stage process can be conducted. The first stage  aims to reduce the content of FFA in oils through esterification reaction using an acid catalyst, the second stage is the production of biodiesel through transesterification using alkaline catalyst. In this study, the esterification reaction is carried out in certain condition. The variables being studied is the effect of the concentration of NaOH catalyst and time of the transesterification reaction. The results shows that the FFA content can be reduced to 0.55% using sulfuric acid catalyst 0.5% by weight of oil, oil to methanol ratio of 1:5 and a reaction time of 120 minutes. Then, oil is converted into biodiesel using NaOH catalyst, obtained a conversion of 83% on the amount of catalyst 0.75% by weight of oil, methanol to oil ratio of 1:7 and a reaction time of 90 minutes. Biodiesel produced has a density of  875 kg /m3, 2.35 cst of viscosity, flash point   of 163oC  and pour point of -2,5oC.

The most important part that commonly used in the processing of aloe vera is it gel, but it has highly water contain and makes aloe vera gel easily damaged and had a low durability against  microorganism invades. The results of preliminary test, the water content in the aloe verathat we use is98,66% - 99,49%, therefore it is necessary for processing into another form with less water contains, that was into flour form. Besides to preserve, this treatment also to increase the selling price of aloe verawhen sold in the form of flour. Aloe vera in the form of flour has several advantages, that is nutritional content is not changed and easy to stored and transported. The advantages of this flour in industry are more practical, stables and not easily damaged. There are a lot of processes to preserve and facilitate the processing of aloe vera, one that is by drying. Among the dryer that can be used in processing aloe vera into powder is using spray dryer. The advantages of this dryer is the contact process was not require a long time. The drying process is performed continuously with the parameters of chamber size, nozzle type (fluid nozzle), the rate of drying air (0,8 m3/min) and the variable are drying air temperature of 60°C, 90°C, and 12°C, feed rate of 2,9 mL/min, 6,2 mL/min, and 13mL/min. This drying process taken places in three stages: the initial stage, drying stages and analysis phase. In this study, we obtained that the best conditions are at temperature of 170 °C with feed flow rate of 2.9 mL/min, a feed moisture content of 99.4%, the water content of aloe vera gel powder at 9.16%, with color powder aloe gel cream pale, pH of 5, microorganism content of 5,33.109sel/g, vitamine C of 114,15 mg/100g sample,and a yield of 0.15%.

Abstract

Air is one of funamental resource for our life. It can be felt directly on the water work of the Air Conditioning (AC), which is currently Air Conditioning (AC) is almost installed in every office building, classroom, even in every home and the water that drains which is condensate AC thrown away. Though water from the condensate can actually be utilized as raw water may even be water unfit for consumption. By utilizing AC performance air condenses into water, where the water will be collected to be known and observed the content contained in the AC condensation process.The basis of this research is that the water from the condensate Air Conditioning can be utilized as the water unfit for consumption because of the great possibility of impurities contained in it only the impurities contained in the air. Early predictions produced water from the air conditioning process will be influenced by the place where the air conditioning was installed.The results of this study indicate that the physical parameters of the AC condensate is colorless, odorless, tasteless, TDS value of 14.27 mg / L, and Turbidity 0.77 NTU. For chemical parameters, pH value of 7.0. Further microbiological parameters indicate that the air conditioning condensate water has a value of <2 for the bacteria E-Coli and Coliform which is the smallest value from Table MPN Series 5. This indicates that the AC condensate is eligible to be used as drinking water.

Abstract

Carrageenan which was extracted from seaweed Eucheuma cottonii has a potential to be modified into hydrogel. In this research, carrageenan was modified with a crosslinking method using glutaraldehyde as the crosslinker and the obtained film was applied to control the substance release rate, namely salicylic acid. The goal of this research was to determine the effect of glutaraldehyde concentration on the parameters of release rate of salicylic acid from the carrageenan film in buffer solution (pH=7,4). The carrageenan was crosslinked using glutaraldehyde solution (1-5%) using film immersion method and thermal curing at 110OC for 25 minutes. Salisilic acid was loaded in the film by immersing film in salisilic acid-aceton solution. The rate release of salisilic acid from crosslinked carrageenan film in buffer solution was determined  by measuring the concentration of salisilic acid  in various time of immersion. It was found that the mathematical model arranged could describe the mass transfer rate of salicylic acid release. The higher the concentration of glutaraldehyde, the consentration of salicylic acid in the film and the constant mass transfer rate tend to be lower, the range around 0,02/minute until 0,015/minute, while the equillibrium constant was higher, the range around 0,0842 until 0,1849 gram of solid/liter

Abstract

This researchcontinued the previous work by Hermawan, Y.D. et al., 2016. The goals of this research wereto tune the process control parametersand to do the closed loop dynamic simulationfor the proposed control configuration of Pure-Capacitive-Two-Tank-in-Series (PCTTS) with an electric heater in tank T-01.The proposed control configuration consisted of 3 couples of CV-MV as follows T1-qe, h1-vpu, and h2-f2. The open loop experiment results would be used for tuning of PID control parameters. In this work, the PID control parameters were tuned quantitatively by using Process Reaction Curve (PRC) method. The controllergain (Kc) for temperature control of tank T-01 (TC-01), level control of tank T-01 (LC-01), and level control of tank T-02 (LC-02) has been found as follows: 364.8 watt/oC, -2.3 volt/cm, and -12.9 cm2/second , respectively. The integral time constant (tI) for 3 controllers were as follows: 60 second, 60 second, and 90 second, respectively. The derivative time constant (tD) for 3 controllers were as follows: 15 second, 15 second, and 22.5 second, respectively. Furthermore, the proposed control configuration and resulted tuning parameters were examined through rigorous dynamic simulation by using scilab software. The input volumetric rate disturbance (with amount of ±29%) was made based on step function. The developed of closed loop state equation was solved numerically. Integral of the absolute value of the error (IAE) for TC-01, LC-1 and LC-2 were 73, 1686, and 695, respectively. The dynamic simulation results showed that the proposed control configuration with its tuning parameters gave a stable response to a change in the input volumetric rate. This study also revealed that the PID controller gave fastest responses compared to P and PI controller.

Abstract

Microalgae have been considered aspotential source of nutritional value. Phycocyanin is one of high added value compound extracted from microalgae that can be used as pharmaceutical products, coloring agent and food nutrition enhancer. Therefore, the potential of phycocyanin need to be explored and developed for its use as an active ingredient in functional food. However, the application of phycocyanin as active compounds in functional foods is eventually accompanied by a stability issue since it is vulnerable to light, moisture content and temperature resulting in the degradation of proteins. Microencapsulation is an effective and economical method to maintain the stability of phycocyanin. One common method of microencapsulation isspray drying, while maltodextrin is the common coating material for spray drying. This study aims to describe the potential of spray drying for phycocyanin encapsulation process. Furthermore, the  characterization of microcapsules psychochemical properties, and evaluate the performance of the storage stability and release controls will be also described. This review discussesnumerous works about the microencapsulation of phycocyanin using maltodextrins as coating material and microencapsulation by spray dying method.
