Acid Functionalization Of SBA-15 Mesoporous Catalyst For Glycerol Esterification To Monoglyceride
Full text linkIn order to exploit the glycerol stream, its transformation into monoglyceride was carried out in the present study. Monoglyceride was produced through glycerol esterification with lauric acid using acid functionalized Santa Barbara no.15 (SBA-15) mesoporous material as catalyst due to high surface area, large pore diameter and hydrothermal stability. The acid functionalized SBA-15 catalysts were synthesized by incorporating two different acid sites, i.e. propylsulfonic acid and sulphated zirconia, on the SBA-15. The SBA-15 incorporated with propylsulfonic acid (SBA-15SO3H) was prepared by refluxing a mixture of SBA-15, dry toluene, trimercaptopropyl trimethoxysilane (MPTMS) at 105 oC, followed by soxhlet extraction for 24 h to propylthiol groups. The SBA-15SO3H catalyst was obtained by oxidation of the thiol group ( -SH) to sulfonic acid form (–SO3H). Meanwhile, SBA-15 incorporated with sulfated zirconia (SBA-15SZ) was prepared by reacting SBA-15 with solution of zirconiumoxychloride and urea at 90 oC to create SBA-15ZrO2. The SBA-15SZ catalyst was obtained by reacting SBA-15ZrO2 with H2SO4 solution at 30 oC. The two types of catalysts were characterized by a number analytical techniques i.e. surface analysis, pulse chemisorption and temperature programmed desorption (TPD) of ammonia, X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), field emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDX), fourier transformed infrared (FT-IR), thermal gravimetric analysis (TGA)

ABSTRACT
The existence of companion books is still inadequate and challenges in the world of education, such as the increase in juvenile delinquency, require legal values to be integrated in learning so that language has a role in minimizing juvenile delinquency that is rampant. Based on interviews, it was found that there are still many students who violate school rules. Therefore, the author developed a companion book with a legal perspective. This research aims to produce Indonesian digital teaching material products with legal insight for class X SMA. The research method used in this study is research and development (R&D) with the 4D development model consisting of four stages: define, design, develop, and disseminate. The results showed that the validation of product feasibility from the aspect of teaching materials received an average score of 4 in the “feasible” category from the interval 0-5. The material aspect with an average score of 4.6 in the “very feasible” category from the 0-5 interval. The language aspect with an average score of 4.4 in the “very feasible” category from the 0-5 interval. Overall, an average of 4.3 was obtained in the “very feasible” category from the 0-5 interval. The results of the learner response value with an average score of 4.0 with the category “feasible” from the interval 0-5 and the results of the educator response value with an average of 4.3 with the category “very feasible” from the interval 0-5. This teaching material received a positive response from learners and educators. This shows that Indonesian digital teaching materials with a legal perspective for high school are suitable for use as companion books in the learning process.

The Optimised Statistical Model for Enzymatic Hydrolysis of Tapioca by Glucoamylase Immobilised on Mesostructured Cellular Foam Silica
Full text linkEnzymatic hydrolysis of starches using free glucoamylase to reducing sugars have difficulties in recovering and recycling of the enzyme, hence immobilisation on inert supports were widely studied. However, effectiveness of the immobilised glucoamylase were merely observed only on soluble starches. It was considered a valuable thing to know performance of glucoamylase on Mesostructured Cellular Foam (MCF) silica in hydrolysing of tapioca. An optimised study on enzymatic hydrolysis of tapioca using glucoamylase on MCF silica (9.2T-3D) and its kinetics were described including justification of the predicted model as it was required to develop in large scale operations. Central Composite Design was used to model the process by studying effects of three factors on DE values after enzyme immobilisation. Immobilisation of glucoamylase on this support gave up to 82% efficiency with the specific activity of 1,856.78 U.g-1. Its used to hydrolysis of tapioca resulted DE values of 1.740-76.303% (w/w) where the highest DE was obtained at pH of 4.1, temperature of 70 ℃ and agitation speed of 140 rpm. The optimisation produced a polynomial quadratic model having insignificant lack-of-fit and low standard deviation, so that it was applicable and reliable in simulating the DE with only 0.80% of data were not described. Temperature affected the process highly, but the buffer pH, agitation speed and factorial interactions were considered not important. KM value for immobilised enzyme was better than the free glucoamylase, however, its reaction rate was slower than the free glucoamylase catalysis. Copyright © 2019 BCREC Group. All rights reserve
Salt-Assisted Mesostructured Cellular Foam (MCF) Silica Synthesis from Bagasse Bottom Ash for Enzymatic Starch Hydrolysis
Full text linkSynthesis of MCF silica is presently conducted solely using TEOS and TMB, with the purpose of immobilizing amylolytic enzymes. Utilizing BBA and KCl to create the salt-assisted MCF silica present a viable option for converting a natural waste into an effective enzyme carrier, given its substantial silica content. The objectives were to produce the MCF silica, to employee the MCF silica as the glucoamylase carrier, and to know characteristics of the immobilized enzyme by conducting hydrolysis of starches. The carrier had surface area of 45.5 m2 g-1, pore volume of 0.12 cm3 g-1, pore size of 9.3 nm, and mesoporous silica type IV. Reduction in the carrier pore diameter and the medium to strong FTIR vibrations indicated free glucoamylase immobilization on carrier. The immobilization reached 88.5% efficiency, influenced by factors such as initial enzyme concentration, PO₄ buffer pH, and temperature, with agitation speed having a minor impact. This optimum value was obtained at the initial enzyme concentration of 9.0 mg mL-1, agitation speed of 120 rpm, buffer pH of 5.5, and temperature of 30°C. Hydrolysis of starches (tapioca, wheat, potato, corn) resulted in Dextrose Equivalent (DE) values ranging from 5.1% to 63.9%, with the immobilized glucoamylase showing better performance in potato starch hydrolysis (DE of 63.9%) and corn starch (DE of 45.6%). The use of BBA in synthesis of the salt-assisted MCF silica proved to be a viable and sustainable alternative for enzyme immobilization, with potential applications in industrial starch hydrolysis
Marketing communication strategy of national indie movies: a case study of Yogyakarta indie movies
No full textIndependent films or more familiarly referred to indie films in general are films produced outside
major label or company/production house (PH). Since it is not marketed through a commercial
distributor line, indie film practitioners or indie filmmakers must be smart and intuitive in searching for
opportunities to promote their work to a wide audience. Although there have been many indie films by
Indonesian filmmakers who won numerous awards both nationally, regionally and internationally, but
the funding problem often hindered their efforts to market their works, so only a handful of spectators
who enjoyed the indie film. This problem was attracted the author to do research on the marketing
communication strategy of national indie movies. In this article, the authors use qualitative research
methods, precisely descriptive-qualitative research methods. Interview techniques, observation, library
study and Focus Group Discussion (FGD) are used to collect all of research data. Data analysis using
case study method. The author has conducted interviews and FGDs with two young producers who are
also indie practitioners in Indonesia, namely Ifa Isfansyah (Fourcolours Films) and Ismail Basbeth
(Hide Project Films). The research results show that indie filmmakers in Indonesia, especially in
Yogyakarta, make film festivals (both national and international) as the main marketing medium for
their works. In addition to using film festivals as a promotional event, indie filmmakers in Indonesia
also use some media/other ways, through social media (Twitter, Facebook, Instagram, Path, and
Youtube), websites that market alternative films (Layaria, ID Film Center, Kineria, VidSee, Buttonijo,
nonton.com) and through press screening

No full textCentral Composite Statistical Design of Tapioca Starch Hydrolysis using Immobilized Glucoamylase on Mesostructured Cellular Foam Silica (MCF-9.2T-3D)
Full text linkBioethanol is a renewable fuel that can be produced from tapioca starch via fermentation pathway. This substrate must be reduced either by enzymatic or acidic hydrolysis. As the hydrolysis of tapioca starch employing immobilised glucoamylase enzyme increase reusability of the enzyme, the process catalysed by the glucoamylase immobilised on/in mesostructured cellular foam silica (MCF-9.2T-3D) was optimised. Effects of temperature, pH of acetate buffer, and agitation speed were studied using response surface methodology based-on central composite design. The saccharification results were analyzed using Design-Expert®6.0.6 software. The model is validated by the F-test for analysis of variance (ANOVA) where p is 0.001. The ANOVA indicated that the acetate buffer pH and agitation speed were not significant, while temperature of hydrolysis showed significant effect. The optimum condition was found at 70⁰C, 4.6, and 140 rpm. The glucose yield at this optimum condition was 2.06 mg/ml, which was equivalent to 68.05% dextrose value
Optimasi Proses Hidrolisis Pati Tapioka Menggunakan Glukoamilase Terimobilisasi pada Silika MCF 9.2T-3D Berdasarkan Response Surface Methodology (Box-Behnken Design)
Full text linkHydrolysis of tapioca using immobilized glucoamylase was studied following a statistical experimental design. The Response Surface Methodology (RSM) based on Box-Behnken design was used in order to obtain optimum operating conditions for the hydrolysis process and to obtain the influence of interaction between variables. There were 3 (three) variables used in this study, i.e. temperature, pH of acetate buffer and agitation speed, which were varied in 3 (three) levels. It was found that the suitable model for this process was the quadratic model. Fit of the model was expressed by the coefficient of determination (R2), which was to be 0.9978 indicating that 99.78% of the variability in the response can be explained by the model. Significance of the model was validated by the F-test for ANOVA, namely p≤0.0001. The model validation showed a good agreement between the experimental results and the predicted responses. The statistical analysis also showed that the optimum dextrose equivalent value (68.406% (w/w)) were obtained at 70°C, 140 rpm and pH 4.6.
