Production of aviation fuel using vegetable oil (Bioavtur) as CPO is expected to be one of the strategic solutions, as Indonesia is the largest palm oil producer in the world. The use of this Bioavtur will also support the Presidential Regulation No. 61 Year 2011 on the National Action Plan for Greenhouse Gas Emission Reduction (RAN-GRK) and the Ministry of Transportation Decree No. KP 201 in 2013 on RAN-GRK Transportation sector from 2010 to 2020, especially in the field of air transport through Indonesia Green Aviation Initiatives for Sustainable Development, The purpose of this study to conduct a prefeasibility production Bioavtur with HEFA process in Indonesia.

The development of Bioavtur itself is still hampered by the fulfillment of the aircraft's very strict fuel technical qualifications. The use of Bioavtur in the CO2 gas recycling cycle, the reduction of exhaust emissions can be generated not only from physical properties and production processes alone using the process of HEFA, ATJ and FT, where Bioavtur does not contain sulfur but CO2 generated from combustion can also be absorbed by Plants that produce raw materials for Bioavtur.

Penggunaan bioavtur bertujuan untuk mengurangi emisi gas buang dari mesin pesawat terbang. IATA sejak tahun 2005 sudah memiliki strategi untuk mengurangi emisi gas buang. Salah satu program yang dilakukan adalah dengan menggunakan bioavtur sebagai bahan bakar. Indonesia sebagai anggota IATA juga memiliki kewajiban untuk melakukan hal tersebut. Oleh karena itu pemenuhan kebutuhan bioavtur di Indonesia sebagai bahan bakar pesawat memiliki peran penting dan stratergis. Bioavtur dihasilkan oleh serangkaian proses konversi biomassa berupa serat, gula, tepung dan minyak nabati. Proses konversi bahan tersebut bisa melalui proses transesterifikasi, perlakuan panas (pyrolisis dan hydrothermal), perlakuan hidrolisis oleh enzim, fermentasi, dan fischertrops.

Herein, the preparation of titanium dioxide (TiO2)-water nanofluid, by using TiO2 nanoparticles (TiO2 NPs) and the cationic surfactant cetyltrimethylammonium bromide (CTAB), was investigated to determine the effects of the sequence method on the preparation of TiO2water nanofluid, its thermal conductivity, its stability, and its temperature distribution. NPs can improve the efficiency of heat transfer fluids and improving the stability of colloidal systems. Some parameters were varied, including sonication times of 5, 10, and 30 minutes, variations of TiO2 loading in 1-8% volumetric loading, concentrations of CTAB (0.005-0.035 wt%), and pH at 8-12. The procedure sequences of 2 and 5 showed the distribution particle size of TiO2 nanoparticles in nanofluid had a narrow range (190.3-208.7 nm) compared to other sequence methods (611 nm-5.35 m). The procedure sequence of 2 is following demineralized water (100 mL), 8% volumetric loading of TiO2 NPs, ultrasonication time of 10 min and CTAB of 3.2×10-3 M, while the procedure sequence of 5 is in the respective order of demineralized water (100 mL), 8% volumetric loading of TiO2 NPs, ultrasonication time of 10 min and pH at 8. The CTAB surfactant (0.029 wt%) had a greater influence on particle distribution in the nanofluid than the pH. The thermal conductivities of the nanofluid were characterized with TiO2 nanofluid as the working fluid. The experimental results showed a maximum of 21% thermal conductivity enhancement for 8% volumetric loading of TiO2 NPs at pH 8 and fourfold increase in critical micelle concentration (0.029 wt%) from CTAB. These findings offer the potential for preparing a stable TiO2-water nanofluid with a short ultrasonic time of 10 minutes. This process is a desirable and very useful to obtain a stable TiO2-water nanofluid with a short ultrasonic time for efficient process and low-cost nanofluid with high

Aloe vera contains various compounds in its leaves, such as vitamins, enzymes, and amino acids. The largest component of Aloe vera leaves is water. Vacuum evaporation is considered to be a potential method in the process to reduce the water content while maintaining the integrity of the nutrients. The objective of this research is to reduce the water content in pureed Aloe vera gel to obtain extracts. Evaporation using a rotary vacuum evaporator is conducted at an pressure of 110 mBar and temperature of 40 °C, and a varied time of 30, 60, 90, and 120 minutes. Analyses of amino acid contents are performed with HPLC. The results show that at 120 minutes, the preserved amino acid contents include: L-Isoleucine 29.3 ppm, L-Proline 10.8 ppm, L-Arginine 9.0 ppm, L-Asparagine 243 ppm, L-Threonine 56.9 ppm, L-Leucine 30.9 ppm, L-Methionine 38.4 ppm, L-Histidine 15.4 ppm, Aspartic Acid 24.4 ppm,...

Microencapsulation proposes to protect sensitive food components, reduce nutritional losses, expand the usefulness of sensitive food components, add certain food to other food, protect flavors and fragrances, convert liquid food components to more convenient solids handled, and protect materials from environmental influences. Product microcapsulation can be used as raw material for the food industry, cosmetics, and pharmaceuticals using bioactive compounds. From the results of the curcuminoid content testings, it can be observed that an increase of drying temperature produces lower amount of curcuminoid contents, which is caused by the inability of curcuminoid compounds to be preserved by maltodextrin, as the microencapsulant. The best temperature to preserve curcuminoid compounds is at 110°C, in which 10.52% is preserved. Hence, for Aloe vera processing, the optimum drying temperature was 120°C which maintained the active component of Aloe vera powder such as Aloenin (B), Aloeresin A, and Chrysophanol.
