The objective of the study was to determine the effects of water addition and steaming duration on starch composition of wheat pollard including starch, amylose, amylopectin and starch resistant. Water was added towheat pollard (0, 30 and 60%) and autoclaved at 121 C (15 and 30 min) afterward. The pollard then was oven-dry at 70 C. The study used a complete randomized design of 3x2 factorial with 3 replications. The addition of water and steaming duration showed a very significant (p< 0.001) impact on the amylose and starch …

Abstract

This study aims to make microparticles of Rutin, a flavonoid compound, at various concentrations with NaTPP-chitosan as matrix. Encapsulation is done by coaservation method. The success of encapsulation was identified by UV-Vis spectrophotometry, Fourier Transform Infra-Red (FTIR) spectroscopy and Scanning electron microscopy (SEM). Based on UV-Vis spectrophotometry analysis, the efficiency of encapsulation (EE) and loading capacity (LC) was obtained at 62,43-94,36 and 1,73- 32,1%, at Rutinconcentration 0,625-11,25 mM. The success of rutin encapsulation is demonstrated by the rutin characteristics of the product seen with the presence of peaks of aromatic rings, indicating the presence of Rutin contained in the chitosan matrix. SEM analysis shows rough and porous surface morphology in microcapsules. The Rutin release profile of the microcapsules is described as two phase processes, burst release at the initial discharge in the first 30 min followed by slow release. At the highest LC (11.25 mM concentration), it provides greater discharge rates for both synthetic fluid simulations 77.53 ± 3.59% and 78.76 ± 4.00% after 3 h of discharge. The controlled release data showed high discharge rates at acidic pH than alkaline pH.

INTRODUCTION

The rutin (quercetin-3-O-routoside, Figure 1) is a flavonoid compound belongs to the flavonol glycoside group consists of a quercetin aglicon and a rutin disaccharide with the molecular formula C27H30O16 (Jantrawut et al., 2013). These compounds have some pharmacological activity, such as anti- inflammatory, antitumor, and antibacterial. It has been reported that this compound has a low oral bioavailability (Almeida et al., 2010). Therefore, this compound is necessary to develope a formula that can

overcome these problems, one of methods is by using encapsulation system (Almeida et al., 2010).

Abstract

The use of biodiesel leads to corrosion of automotive material, which can potentially shorten engine lifetime. The study aims to investigate the effect of temperature and contact time on the corrosion characteristics of carbon steel upon exposure to biodiesel synthesized from used frying oil. The corrosion rate of carbon steel was analyzed based on weight loss measurement according to the standard of ASTM G31 as affected by temperature and contact time. The immersion temperatures used in this study were 30ôC, 40ôC, and 70ô, respectively. The contact times studied were 30 days, 40 days, and 50 days respectively. The results show that the increase of temperature and contact time of biodiesel on carbon steel surface speeds up the corrosion rate. Maximum corrosion rate (0.083 mmy) was observed on the carbon steel contacted to biodiesel at 70ôC for 50 days. The SEM results showed an irregular shape of the corroded carbon steel surface. XRD / FTIR analysis of carbon steel samples show the presence of peaks, detected as Fe2O3, FeO(OH) and Fe2O2CO3, as the corrosion products.

INTRODUCTION

The advances of technology in industrial and transportation activities lead to the rapid increase of fossil fuel consumption so that its supply will decrease rapidly. Because fossil fuels are not renewable, this situation may lead to the crisis of energy in the future (Jin et al., 2015). Nowadays, the world main issue in transportation is dominated by the use of petroleum based fuels, such as gasoline and diesel. Globally, the average energy consumption in transportation

increases as much as 1.1% each year as the result of automotive industries development. The transportation sector has been estimated to contribute about 63% in liquid fuel consumption since 2010 until 2040 (Mahmudul et al., 2017). In addition, burning of fossil fuel causes environmental problem, especially in the form of air pollution (Thangavelu et al., 2016).

Various efforts have been made to find alternative renewable energies as substitute to fossil fuels so that the fossil fuel consumption rate in the future can be

Abstract

The human population continues to grow and so does the volume of textile products. Most of textile wastewaters contain synthetic dyes, which are mostly treated by less effective conventional wastewater treatment processes. Treatment using activated carbon is able to remove the dye from wastewater, but it is a high cost material. Rich organic carbon material, such as compost, might be an alternative solution. The objective of this study was to assess the capability of compost in treating dye wastewater by investigating the effect of compost dosage, particle size, and column height based on dye percentage removal and adsorption capacity data. A removal percentage of 20.49% and adsorption capacity of 5.33 mg/g were achieved when 200 ppm of Congo Red dye molecule was treated using 1-2 mm compost particles with dosage of 8 g/L. In addition, 90% dye removal and 0.38 mg/g adsorption capacity can be obtained when compost column height 60 cm was used. After a while, the dye molecule wore off the compost and fresh compost must be introduced into the system to maintain its percent removal. The Langmuir model successfully described the adsorption isotherm of Congo Red dye on compost particles.

reaktor.17.4.203-209 INTRODUCTION

As the human population continues to grow, so does the number of textile products. Alongside the products, wastewater is simultaneously produced.

Since only 50% of dye is absorbed by the fiber during dyeing process, textile wastewater becomes one of the most polluting wastewater (Clarke and Anlicker, 1980; Harrelkas et al., 2009; Laxman, 2009). The synthetic dye can reduce light penetration to water, causing detrimental effect on the photosynthetic

activity of aquatic flora, and therefore affecting the food source for aquatic organisms (Reddy et al., 2008;

Upadhyay and Mahajan, 2014). It also forms chelated metal ions, which are toxic to aquatic organisms (Hunger, 2003; Toptas et al., 2013,).

The dyes that are commonly used in the textile industry can be classified into two categories: anionic and cationic (Ghaly et al., 2014). One of the anionic dyes oftenly used in textile manufacture is Congo Red, a synthetic diazo dye that is easily dissolved and is

Abstract

This study aims to obtain titanium dioxide (TiO2) fine particle with a narrow size distribution by one step production via flame spray pyrolysis (FSP) using LPG (liquid petroleum gas) as a fuel source. The TiO2 particles were synthesized from the aqueous based precursor from dissolving of titanium (IV) isopropoxide to the acidic distilled water solvent. The effect of precursor concentration on the crystalline structure, morphology and size distribution of the TiO2 particles were systematically investigated. There were observed that the TiO2 has a uniform spherical shape with particle size around 200-500 nm. Increasing the precursor concentration resulted in the size distribution shifted toward the bigger size. The crystalline structure of TiO2 product showed the mixed phase of anatase and rutile and had a large specific surface area  850,343 m²/g.

INTRODUCTION

Titanium dioxide (TiO2) is an N-type oxide semiconductor material having an energy band gap of 3.2 eV. TiO2 particles have been widely used as primary materials in energy converting devices such as solar cells (Jeong et al., 2016) and catalysts on hydrogen production (Pan et al., 2016). In addition, the particles are highly environmentally friendly

photocatalyst materials that can be applied in the process of degradation of organic pollutants (Bettini et al., 2015), self-cleaning process (Kim et al., 2016), anti-bacterial and anti-odour (Fagan et al., 2016).

Research and utilization of TiO2 particle get a lot of attention because of its very diverse applications. TiO2

also has quite interesting properties including non- toxic, stable, abundant and relatively economical. (Kim
