Abstract

Attention deficit hyperactivity disorder (ADHD) is the most common childhood neurobiologic disorder with main  symptom of inattention, hyperactivity, impulsivity and minimal occurrence in two different place settings, for example at home and at school. ADHD disorders will last sustainably from adolescence to adulthood. Mothers of ADHD children tend to be anxious, tired and desperate because they are often blamed by the environment for failing to educate children due to opposing childrens behavior, disobeying orders that result in ADHD children being rejected and experiencing low learning achievement. Mothers are also often must lose his job due to having to take care of his own ADHD child.Methods: Observational analytic study with cross sectional design of 30 mothers of ADHD children aged 6 to 12 years of Bina Karya primary school Surabaya by random sampling method. Assessment of ADHD by mothers using SPAHI (Skala Penilaiana Anak Hiperaktif Indonesia)  and maternal anxiety  assessment using Hamilton Anxiety Rating Scale questionnaire Results: there was significant correlation between maternal anxiety level  and severity of ADHD with score p = 0.003 and r = 0.530 Conclusion: The degree of maternal anxiety is related to the severity of ADHD.

Abstract

The color of natural dyes, as anthocyanins, is very easily changing as he temperature changes. The color change can be used as a color indicator to provide information about product deterioration due to its sensitivity toward temperature and light. This indicator is called smart label of color indicator. This film label can be made of chitosan and polyvinyl alcohol and extract of erpa (Aerva sanguinolenta) leaves. The extraction was done under various leaf:water ratios. The filming was done in 2 methods, i.e. (i) by mixing the extract into film solution and drying the film at 50 °C; and (ii) by brushing the extract on the film surface. The leaf extract had a pH of 5.09 and the total yield of 116.65 mg anthocyanin/100 g leaves. Filming of color indicator in mixing method and dried at 50 °C resulted a colorless film. Brushing method was the best method to produce smart label with quite stable property and 1 mL extract could be applied evenly per 40 cm2 film area. Thus, this film can be utilized as smart label with color indicator to detect the deterioration in temperature-sensitive products.

Abstract

Active packaging is a technique that can be developed to prolong shelf-life or enhance safety or sensory properties, while maintaining the quality of fresh products inside. This experiment produced active packaging of antimicrobial (AM) film in which an antimicrobial (AM) agent was added into the film (instead of food) and then used it to coat the food product. The AM agents slowly release into the product surrounds, inhibit the growth of microbes thus packing and preserving were done in a single step. Carragenan was chosen as a matrix film with garlic extract as an AM agent. Fish balls were chosen as a product to be coated by this AM film. The study consisted of 2 steps i.e.: (i) prepared AM film, and (ii) coated the fish balls with AM film and then tested the quality during storage. In general, the quality of fish balls before and after storage still meet the SNI 0-3819-1995. In the application, the fish balls with AM film has longer shelf life than that without AM. Further more, the result of organoleptic test on appearance of odor and color showed that the panelists prefered coated fish balls than the uncoated one. The panelist prefered coated fish ball which is stored at 5 and 15°C.

Abstract

Torbangun soup is made by traditionally recipe as Batak cuisine. A packaging technique has applied by canned the soup to produce Torbangun soup for commercially market. An antioxidant is added to prevent rancidity and to prolong shelf life of canned soup. Regarding to quality analysis, the shelf life of canned Torbangun soup is 14 days in room temperature. The effort has been done by storage the product in cool temperature (5 - 8°C and 10 - 12°C) and resulted in longer shelf life until 22 days. In spite of antioxidant adding, pasteurization at temperature of 75°C for 15 minutes prior canned can result on longer shelf life of the soup. However, can is metal and it might some hazard substance migrate into product. The study showed that the amount of the total residue migrate from can into soup is lower than 10 mg/dm2 allowing by the Directive 90/128/EEC for aqueous food simulant. A total migration test using 95% alcohol gave a value of 37.4435 mg/dm2, means higher than that EU standard as 10 mg/dm2. Keyword: Torbangun leaf soup, total migration, canning method

Abstract

Background Zinc deficiency is common in children in develop-ing countries and data suggests the effects are detrimental towardschildren’s growth and neuropsychologic performance. Results ofmultiple studies which assess these effects have been inconsis-tent.Objective To evaluate the effects of zinc supplementation onnutritional status and cognition in children with zinc deficiency.Methods Forty-six stunted children aged 50-80 months with lowhair zinc levels were randomly assigned to receive either 7.5 mgelemental Zn or placebo twice a week for 3 months. Anthropom-etry and cognition were assessed at the beginning and the end ofthe supplementation period. Differences among both groups foranthropometry and cognition before and after supplementation wereanalyzed with paired t-test. A comparison of different anthropom-etry and cognition among the two groups were analyzed using theindependent t-test.Results There were no significant differences among baselinecharacteristics except on sex distribution.There was a significantdifference in weight for age between the zinc group and placebo[0.28 (SB 0.18) vs 0.09 (SB 0.14); P=0.0001]. Height incrementswere also greater in the zinc group [0.34 (SB 0.15) vs 0.02 (SB0.12); P=0.0001). There was no significant difference betweenweight for height. Intelligence quotient (IQ) measured by theStanford-Binnet test was slightly higher in the zinc group [2.26 (SB3.11) vs 2.00 (SB 2.81], but the difference was not significant ac-cording to sex.Conclusion Zinc supplementation produced highly positive re-sponses in weight for age and height for age increments in chil-dren with zinc deficiency compared with placebo. There was noeffect of zinc supplementation on weight for height index and noneon cognition measured by intelligence quotient (IQ)

Abstract

Bioactive compounds in Eucheuma cottonii include phenols or polyphenols with antioxidant, antibacterial, and antiviral properties. Seaweed quality, including phenolic content, is highly determined by several factors, including the growth location, cultivation technique, and harvest age. This study aimed to determine the effect of harvest age and solvent type on the phenolic content of E. cottonii. The effects of harvest age on water content and of simplicia on the extraction process were also determined. Phenolic active ingredients were extracted at three harvest ages (35, 40, and 45 days) and using four solvents (ethanol, ethyl acetate, hexane, and water). Analysis of variance was performed to determine the effects of both factors and their interactions. The older the seaweed, the lesser the water content. The powder produced at all ages is a good simplicia for materials extraction. Results showed that high phenolic content was obtained from the E. cottonii extract at the age of 35 days with ethyl acetate as the solvent.

Abstract

Good product packaging is one of the fundamental factors in determining the quality of a product. Along with the development of science and technology, modern packaging has evolved into intelligent packaging, which can directly communicate with consumers about the quality and quality of the packaged products without opening the package. One of the smart packaging trends being developed is thermochromic ink, or thermochromic ink that can be applied in the form of films or packaging labels. Thermochromic inks change color as processing and storage temperatures change. Smart packaging in the form of thermochromic ink (Thermochromic ink) uses one of the ingredients, namely the leuco dye system. The leuco dye system consists of 3 main components, namely dye, developer and solvent. Limitations in manufacturing thermochromic ink are that the dyes and developer materials used are toxic, which can pose a risk to human health when these materials migrate from packaging to packaged food products. Therefore, it is necessary to characterize the dye (dye) against temperature and pH changes. The purpose of this study was to characterize the dye used to produce thermochromic ink with the best color change. Characterization of dyes using pH indicator dyes include Bromothymol Blue, Bromophenol Blue, Bromocresol Purple, Bromocresol Green, and Methyl Red. 15 mg of pH indicator of each dye was dissolved in 10 ml of 97% ethanol and then immobilized on filter paper at room temperature for 24 hours. Test the indicator dye's sensitivity to NH3 vapor by simulating NH3 vapor from NH4OH evaporating in a closed, airtight container. 10 mL of 1N NH4OH solution and 5 mL of each dye solution were placed in the same closed glass container. The variables observed were color changes and pH changes at 0, 5, 10 and 15 minutes.

Abstract

Smart packaging is the packaging that can monitor and provide the information about quality of the packed product. This study was aimed to produce a label with indicator ferri sulphate (FeSO4) to detect H2S produced by poultry and to study the color change of the label response to H2S exposure. Preliminary study showed that the best label was obtained with the formula of 3 grams chitosan, 70 ml acetic acid 1%, 30 ml aquadest and 2,5 gram FeSO4. It was also known that H2S concentration increased during storage at room temperature, from 0 ppm at the first hour to 18.3 ppm at 120th hour. There were significant differences in the value of L, a, b and °hue at α = 5%. Lightness value decreased from 34.26 to 7.44 in the end of storage. Value of a changed positively to red color, from 17.17 to 32.45 and value of b turned negative from 51.67 to 10.26. Therefore, °hue showed that at 0-24 hours indicator was in yellow-red zone, at 24-96 hours in red zone and at 120 hours in red-purple zone. Further, the study showed that meat stored in room temperature for 24 hours already spoiled. Microorganism was also detected to grow more during storage. The growth in the beginning was 7 × 105 cfu/gram and became 71.5 × 105 cfu/gram. Based on SNI, the limit for microorganisms is 10 × 105 cfu/gram. Ferri sulphate could be used as spoilage detector by changing the indicator color from yellow-red to dark brown.
