Abstract

The aim of this research were to evaluate the chemical compositions and antibacterial activities of patchouli. The identification of patchouli oil was carried out by using gas chromatography-mass spectrophotometer, fractionation of patchouli oil was done by vacuum fractionational distillation method. The gas chromatography mass spectra showed that the patchouli oil consisted of 15 components. It was found that the five major components were patchouli alcohol, Δ-guaiene, α-guaiene, seychellene and α-patchoulene. Patchouli oil and high boiling point fraction exhibited antibacterial activity, while the low boiling point fractions did not show the antibacterial properties. The antibacterial properties found to be more effective for the Gram-positive bacteria than that the Gram-negative bacteria.Key words : patchouli oil, patchouli alcohol, fractinational distillation, antibacterial

Abstract

Abstract The aim of this research is to obtain the Phospholipid characteristic of Calophylluminophyllum which is suitable with the need by means of fractination process.Phospholipidcharacterisation resulted from fractination will generate recommendation of Phospholipidfractination use on suitable product and food processing. The extraction process was performed by using chloroform-methanol (1:2 v/v). The polar lipid is separated by using ethanol, then ethanol is used to extract Phospholipid. Fractination was performed based on the soluability in ethanol and acetone. There were 5 Phospholipid fraction namely crude Phospholipid (without fractination), ethanol soluble, ethanol insoluble, ethanol-acetone insoluble fraction. Each fraction was characterised for phosphatidylcholine content (PC), hydrophilic-lipophilic balance (HLB), peroxide value, viscosity and color. The result showed that the highest PC content was found on ethanol-soluble fraction, whereas highest fatty acid which arrange Phospholipid werepalmitat (C16:0) and Oleat (C:18). Phospholipid fraction which is suitable to be used as oil in water emulsifier is ethanol soluble fraction, and ethanol insoluble fraction is used as water in oil emulsifier. Keywords: Calophylluminophyllum kernel, phosphatidylcholine, phospholipid, phospholipid characteristic

Abstract

This research were aimed to know the plumbum (Pb) and cadmium (Cd) profile on soybean seeds as contaminants of the impact use of agrochemistry material impact and to know of swelling agent of N,N-dimethylformamide (DMF) needs at certain level of pH in chelation with citric acid. The results showed that the content of Pb in soybean seeds at cultivation system agrochemistry materials i.e. 0.63 ppm, while cultivation system without agrochemistry materials i.e. 0.46 ppm. Cd content in soybean seeds at cultivation system agrochemistry materials i.e. 0.05 ppm and the cultivation system without agrochemistry materials i.e. 0.1 ppm. Acceptable daily intake in terms of Pb content in soybean after treatment increases to 2.93 times compared before treatment (11.3379 to 33.2099 g per body weight per day). Acceptable daily intake in terms of the content of the Cd in soybean after treatment increases to 5.26 times compared before treatment. The value of the bio-concentration factor which expressed an accumulation of Pb in soybean seeds on both cultivation is low system (BCF<250), while for Cd is a moderate to high level (1.000<BCF>250). Cd reduction on soybeans seeds for all chelation treatment was maximum (not detected-detection limits was 0.01 ppm), while the highest reduction of Pb occurs at swelling agent N, N-dimethylformamide 15 mL at pH 10.

Abstract

Despite the fact that technological innovation and its role in the economic growth of developed countries have been much studied, but there is only little knowledge about the factors that determine technological innovation in Indonesia. In an effort to fill this gap, this study is conducted with the aim to analyze the factors that affect innovation in the food industry inIndonesia. Analytical methods used to achieve the research objective are regression analysis with 2 SLS (Two Stage Least) method and qualitative analysis. The results showed that there sixteen factors that influence technological innovation in the Indonesian food industry. By usingfurther 2 SLS method, empirical observation, in-depth interviews and discussions with experts, it is obtained the strong of technological innovation determinants to enhance technological innovation in the food industry. The determinants include the style of leadership, human capital,learning orientation, the company's ability to provide incentives / rewards, company relationships with outsiders and corporate location.

Abstract

Hard and crunchy are specific characteristics of fried product prefered by consumer. To have texture of crunchy product being suitable with consumer taste, it is necessary to observ characteristic change of raw material and frying condition. In frying process, the changes of hardness and crunchiness characteristics of food occur. These changes are predicted caused by free water vaporization and the decrease of starch content in food. The objective of this research is to develop mathematical model of hardness and crunchiness changes as the function of water and extract content degradation. Sample of the research is jack fruit fried in the temperature of 70–100° C, duration of 15–60 minutes, and pressure of 80–90 kPa. The parameters observed are hardness and crunchiness, water and starch content before and after frying. The result showed that hardness and crunciness change as the function of water vaporization and the decrease of starch content can be used to predict hardness and crunciness of product during vacuum frying.

Abstract

Indonesia's commitment to reducing the use of fossil fuels for power generation has encouraged the exploration of biomass energy from waste materials. Organic Rankine cycle (ORC) turbine technology that converts waste into electrical energy can be an opportunity for the development of waste power plants. The developed ORC turbine has not been assessed for innovation readiness level (IRL). To address this gap, a comprehensive evaluation of the IRL and technology readiness level (TRL) of the ORC turbine is essential. This study uses qualitative and quantitative methods, combining the IRL and TRL frameworks. The results reveal that the ORC turbine market is ready, although the technology is still in the early stages of development (IRL 2). In order to achieve IRL 3 and be prepared to enter the decline stage as part of the market evolution phase, intellectual property protection, product testing, and certification must be carried out. The establishment of a product certification agency with testing facilities to ensure turbine performance is required. IRL and TRL approaches can be used to determine the stages of research activities that can be achieved by looking at the availability of resources needed at each level.

Abstract

The objectives of the research are to evaluate fatty acids profile, oxidative and hydrolysis stability of human milk fat (HMF) analog by using virgin coconut oil (VCO) and palm stearin as raw materials. The HMF analog was synthesized through enzymatic interesterification catalyzed by lipase from Rhizomucor miehei. The fatty acid profiles of interesterification products were monitored using gas chromatography. Oxidative stability test was carried out for up to 72 hours at 60oC. The peroxide value was measured during 0, 24, 48 and 72 hours of storage duration. Hydrolysis stability test was held for up to 8 days at room temperature. The free fatty acid content was monitored during 0, 2, 4, 6 and 8 days of storage. The results showed that the resulted HMF analog having high percentage of palmitic acid in the sn-2 position, similar to that of HMF. The palmitic acid content in the sn-2 position was around 39.71%. The MCFAs were esterified in the sn-1 and sn-3 position and the main fatty acid constituent was lauric acid of 39.37%. The obtained HMF analog was stable to oxidative and hydrolysis deterioration as indicated by the peroxide value and free fatty acid content during storage.
