Abstract

 As beef consumption can increase risk of cancer and cardiovascular disease, an alternative food in the form of synthetic beef which contains important nutrients with less health risk can be made. In this research, protein content will be derived from gluten, kidney bean, soy pulp, and textured vegetable protein which are varied in concentration. Our results indicated that increase of kidney bean flour and textured vegetable protein will increase ash, protein, and fat content while increase of soy pulp will increase water and carbohydrate content, decrease the amount of calories, and reduce synthetic beef’s hardness. The best synthetic beef has been made with a combination of 60% gluten, 10% kidney bean flour, 20% soy pulp, and 10% textured vegetable protein. According to proximate and calorimetry analysis, the best synthetic beef contained 60.3% water, 0.6% ash, 19.3% protein, 4.5% fat, 15.6% carbohydrate, and 178 kal/100 g. According to texture profile analysis, the best synthetic beef had 0.570 cohesiveness, 5845.4 gf hardness, and 88.0 springiness. Synthetic beef has similar cohesiveness and elasticity but higher hardness than beef. Based on this research, synthetic beef with sufficient amount of nutrient and less health risk has been produced.

Abstract

The thickness of steam chest is found by integrating the steam velocity with respect to breakthrough time. The bigger rate of steam injection would form the thinner steam chest, which has affected to the cost required to production of steam that would be injected to the reservoir. There is a difference between the theoretical breakthrough time and steam chest calculations with the actual field situation. The difference occurs because in the theory used the ideal condition in which the heat efficiency is perfect, but in the actual field, there are many factors that cause the heat efficiency such as the slope of layers, reservoir heterogeneity, pressure gradient, and permeability distribution.

Abstract

This research modified pectin with crosslinking method using CaCl2, so the structure could be applied as Drug Delivery System. Salicylic acid, known as an antibiotic, was added to the crosslinked pectin film. The aim of this research was to evaluate the effects of the CaCl2 concentration as a crosslinker on the release rate of salycilic acid from pectin film in the buffer medium. The research included four steps i.e crosslinking pectin film, loading salycilic acid into the crosslinked pectin film, release test of salycilic acid in the buffer medium with pH=7,4, and data analyzing. Based on the research, the higher crosslinker concentration (0.02 g/ml; 0.05 g/ml; 0.1 g/ml; and 0.15 g/ml), made the pectin structure was denser, thus the amount of salycilic acid loaded in the film was less. The derived mathematic model could describe the mass transfer of salycilic acid. The higher of CaCl2 concentration caused the equilibrium constant (H) increase in the range around 0.235 until 0.7048, while the rate constant of salycilic acid mass transfer (KCA)tended to decrease, in the range 0.016 until 0.11.

Abstract

The Immobilization Of Radioactive Wastes Generated From Molybdenum-99 (Mo-99) Radioisotope Production Using Titanate Synroc Matrix Materials. The assessment of immobilization technology using synroc matrix material for the long life radioactive liquid wastes generated from Mo-99 radioisotope production containing of uranium, transuranic and fission product elementswas carried out. For that purpose have been developed the titanate synroc matrix material by hot isostatic pressing process. All basic science studies confirm that the leach-rates and a-decay damage in synroc relatively very low and acceptable.  In Indonesia, adaptation of immobilization technology using titanateof synroc matrix materials was carried-out for immobilization of the long life radioactive liquid wastes generated from 99Mo radioisotope production by sintering process at high temperature. Immobilization process was carried-out by mix the radioactive waste with  precursor oxides, then drying the mixture at 100 oC, calsination at 750 oC, then it was preesed in the moulder. Further process are  sintering at the temperature of 1000-1300 oC with the time 1-4 hours to form the solid multiphase ceramic. The composition of  precursor oxides for titanate synroc (in % weight) i.e :  Al2O3  (5.4);  BaO (5.6);  CaO (11.0); TiO2 (71.4) and ZrO2 (6.6). Waste loading in the waste synroc block are 10 – 60 % weight. The quality of the synroc block was determinated by testing of density, pressing strength, and leaching-rate. The testing results showed that the best quality of waste synroc block was obtained at the waste loading 20% weight, sintering process at 1200 oC for 3 hours with values of density 3.35 g/cm3, pressing strength 14.18 kN/cm2, total leaching-rate 2.5.10-3 g.cm-2.day-1 , and leaching-rate of Cs, Sr, and U are  4.1x.10-4 g.cm-2.day-1, 2.3x10-6 g.cm-2.day-1 and 6.3x10-7 g.cm-2.hari-1 respectivelly. The titanate synroc matrix materialscan succeed for immobilization of liquid radioactive waste containing of U, Cs and Sr elements, so that it is very good for immobilization for the radioactive waste generated from 99Mo production.

Abstract

This study aims to determine the effect of sheep manure and EM4 in composting procces duration using Takakura Methods. The research conducted in laboratory scale using cabbage waste from the nearest market in Cimahi. Another variation are the concentration of sheep manure (10% and 30%) and EM4 (10 ml and 15 ml). There are four samples were done in this study, A (cabbage waste+10% sheep manure +10 ml  EM4), B (cabbage waste+ 30% sheep manure+ 10 ml EM4), C (cabbage waste+10% sheep manure + 15 ml EM4), D(cabbage waste+30% sheep manure+15 ml EM4.) Expectations of this study was produced compost that meets the quality standard of organic fertilizers based on SNI 19-7030-2004 such as C/N ratio, pH, and temperature.The results showed that cabbage waste can be composted after 20 days, its faster than the conventional composting technique. All the samples at the end of composting procces has pH 7, temperature 260C, blackish brown color, and a slight smell of soil. The C/N ratio in each sample is 9,7 (A), 9 (B), 7,43 (C), 8,67 (D). A sample has a value close to the quality standard of organic fertilizers based on SNI 19-7030-2004.

Abstract

Two established chemical delignification method employing sulfuric acid and sodium hydroxide are often used for lignocellulosic material. In this study, the enzymatic hydrolysis of coconut coir with 1.5% dilute sulfuric acid delignification at 105°C  were evaluated. This reaction is one of the stages in the process of converting lignocellulosic biomass into alternative fuels. The reducing sugar as a product of enzymatic hydrolysis can be further fermented to yield bioethanol or biohydrogen. Experiments were conducted for various concentrations of coconut  fiber (i.e. 0.1; 0.2; 0.4; 1 and 2 g/100mL).  Data from the experiment were then modeled by the power model so that the parameters can be determined. It was found that model parameters were different for each coconut fibre concentrations. The power model fits well with the experimental data as indicated by their R2 values.

Abstract

Batteries are often used in mobile phones is a type of battery Li-Ion or Lithium Ion Battery (LIB). Cobalt and lithium used in batteries is important metal that is often used in various fields. Batteries that are not used become hazardous waste. Metal recovery from waste batteries is one solution to maintain the availability of raw materials of lithium and cobalt. In this study the recovery of lithium and cobalt was done with leaching method, which dissolves metals from the waste battery into the leaching agent. Citric Acid (C6H8O7) was used as the leaching agent, because it is one of the organic acids that can be used in the leaching process lithium. The results showed that the metal content in batteries LIB 35.30 ppm lithium metal and 408.55 ppm cobalt metal. The concentration of leaching agent take effect on the percentage of leaching. The optimum operating conditions for the leaching process is at a concentration of citric acid of 1.5 M; with a contact time of 30 minutes and a temperature of 55 ° C.  In these conditions, the optimum percentage was obtained for the leaching of metal lithium and cobalt are 98.08% and 86.28%, respectively, respectively.
