Authors: De Souza Colau Laura , Pereira Talitta , Vieira Almeida Silva Juliana , Sesti Becker Ana Paula , Sardá Junior Jamir
Published: August 2022

A adolescência pode corresponder ao período de maior vulnerabilidade ao desenvolvimento, cujas crises de comportamento autolesivo sem intenção suicida, seja emergente em situação adversas. Para tanto, este estudo teve como objetivo geral analisar a produção científica nacional sobre autolesão não suicida, automutilação e adolescentes. Realizou-se uma revisão integrativa da literatura, cujas bases de dados nacionais foram o SciELO, LILACS e PePSIC. As estratégias de busca foram “Autolesão não suicida OR automutilação AND adolescência OR adolescentes AND terapia Cognitivo-Comportamental OR psicoterapia”. Consideraram-se os estudos nos idiomas português, inglês e espanhol, entre 2009 a 2020. Após a definição dos critérios de inclusão e refinamento, foram retidos onze estudos, os quais foram analisados pelos aspectos metodológicos e temáticos. Os resultados demonstraram que, embora as pesquisas nacionais encontradas nos últimos dez anos, tenham abarcado como temática principal, adolescentes que apresentassem comportamentos autolesivos, nenhum estudo que sugerisse estratégias de enfrentamento e de cunho psicoterapêutico, dentre os trabalhos analisados, foi encontrado. Considera-se a importância no avanço de pesquisas que privilegiem não somente o impacto do transtorno para esta população, mas que apontem estratégias e recursos psicoterapêuticos, além de medidas protetivas que promovam o seu enfrentamento e oportunizem desfechos positivos no manejo com a problemática.

Published: August 2022

This study assessed the effect of the dumpsite and vehicle exhaust on green leaf vegetable (Amaranthus hybridus), Jute-ewedu (Corchorus olitorius), and spinach (Amaranthus oleracea) by examining the heavy metal distribution in three vegetables from Ipaja farm (farm near a dumpsite), and Ikola farm (farm close to the tarred road) and compared with the concentration of heavy metals from Shasha farm (a secluded farm) and World Health Organisation/ Food and Agriculture Organisation (WHO/FAO) standard. The leaves of these vegetables were air-dried, digested, and analysed for the presence of Arsenic (As), Magnesium (Mn), Copper (Cu), Zinc (Zn), Lead (Pb) and Cadmium (Cd) using Atomic Absorption Spectrophotometry. The heavy metals values at Shasha farm were within the permissible range set by WHO/FAO. However, at the Ipaja farm, Lead and Cadmium were beyond the WHO/FAO permissive range in green-leaf (2.311±0.003mg/kg, 0.201±0.013 mg/kg), while only Lead in Jute-ewedu (2.011±0.003 mg/kg) and Spinach (2.011±0.003mg/kg). At the Ikola farm, Arsenic, Lead and Cadmium were beyond the WHO/FAO acceptable value in green vegetable (0.329±0.012 mg/kg, 4.122±0.007 mg/kg, 2.941±0.0011 mg/kg), while only Lead and Cadmium in Jute-ewedu (3.241±0.007mg/kg, 2.391±0.005 mg/kg), and Spinach (3.69±0.015mg/kg, 2.32±0.004 mg/kg). The increase in the metal concentration from the Ipaja farm suggests the feasibility of metal mobility from the dumpsite to the nearer farm. Also, vehicular exhaustion may contribute to the increase of Cadmium and Lead present in the vegetables planted along the tarred road. Government should dissuade citizens from creating improper dumpsites and ensure vegetable farms are cited away from the main road.

During the coronavirus disease-2019 (COVID-19) pandemic, which was caused by the novel coronavirus, there is an ongoing controversy about the use of corticosteroids. This study aims to investigate the association between Dexamethasone treatment and clinical outcomes in patients with severe COVID-19. In this single-center retrospective cohort study, patients with COVID-19 were enrolled from February 16, 2020, to November 1, 2020. After performing propensity score matching with age, sex, and disease severity. The independent effect of Dexamethasone treatment on in-hospital mortality was evaluated by multivariate proportional hazards regression models. Of 1413 patients with COVID-19 diagnosis, 1172 patients entered the final analysis. 473(40.4%) patients received dexamethasone treatment with a median duration of 6.0[4.0-9.0] days. After matching and adjustment with possible confounders in the multivariate model, administration of dexamethasone significantly increased the survival in severe patients (hazard ratio: 0.25, 95 confidence intervals: 0.16-0.38, P<0.001), but there was no difference in non-severe patients (P:0.888). The administering of dexamethasone was associated with an increased in-hospital survival rate (HR: 0.25 [0.16-0.38]) in severe COVID-19 patients. The survival rate was more significant in severe patients with diabetes mellitus or hypertension after receiving dexamethasone treatment (HR:0.19). On the other hand, patients without severe disease did not benefit from dexamethasone administration.

Vitiligo is the most common cause of skin depigmentation, which relates to a wide range of psychological disorders. Stigma is defined as a negative attitude towards oneself that results from one's perception of being different from the general population. In this study, we have evaluated the quality of life and stigmatization degree among vitiligo patients. In this cross-sectional study, 323 patients with vitiligo referred to Razi Hospital, Tehran, Iran, were evaluated. All patients were asked to fill out a questionnaire containing age, gender, marital status, educational level, employment status, duration of vitiligo, location of lesions, history of underlying diseases, history of previous treatments, as well as history of depression or suicide. Quality of life and stigmatization among patients were assessed by DLQI (dermatology life quality index) and FSQ (feeling stigmatization questionnaire) questionnaires. The prevalence of moderate and severe stigmatization were 49.8 % and 13.3%, respectively. Women were significantly more stigmatized than men. The presence of vitiligo lesions on the face, hands, or forearms, previous topical and oral treatments, and prior depressive disorders were significantly associated with an increased sense of stigma. Patients with thigh or trunk lesions faced less stigmatization. Additionally, stigmatization was meaningfully related to the level of quality of life impairment. In the present study, 63% of patients with vitiligo experienced moderate to severe stigmatization levels related to gender, lesion site, history of prior treatments, and depression. Moreover, there was a significant correlation between the level of stigma sensation and the life quality disturbance.

Authors: Mirzaasgari Hosna , Momeni Fereshte , Pourshahbaz Abbas , Keshavarzi Farahnaz , Hatami Masoud
Published: August 2022

Background: Assisted reproductive technology treatments are stressful procedures, but there are individual differences in the emotional response to them. Differences in response to this stress may be related to the outcome of infertility treatment.
Objective: This study aimed to investigate the relationship between coping strategies and infertility self-efficacy with pregnancy outcomes of women undergoing in vitro fertilization/intracytoplasmic sperm injection treatment.
Materials and Methods: This was a prospective cohort study and the 154 infertile women were psychologically evaluated in 2 stages: once before ovarian stimulation and again during embryo transfer. The research measurements used were the Revised COPE, the Depression Anxiety Stress Scale (DASS-21) and the Infertility Self-Efficacy Scale.
Results: There was no significant difference between the group of non-pregnant women and the positive pregnancy group in terms of coping strategies (mental rumination, self-blame, active confronting, goal replacement, avoidance) or self-efficacy in either of the 2 stages of ovarian stimulation and embryo transfer. The Mann-Whitney test did not show any statistical difference between the clinically pregnant women and the only laboratory positive pregnant group. Moreover, the self-blame and mental rumination strategies were positively related with anxiety and depression. Conversely, active confronting, goal replacement, avoidance and self-efficacy were associated with decreased depression, anxiety and stress levels.
Conclusion: It can be concluded that there is no relationship between coping strategies and infertility self-efficacy with in vitro fertilization/intracytoplasmic sperm injection outcomes. Further research is needed to clarify the effects of other psychological factors on the pregnancy outcomes of assisted reproductive treatment.
Key words: Coping strategy, Self-efficacy, Infertility, In vitro fertilization, Depression, Anxiety.

Efficient Recovery of Lignin and Hemicelluloses from Kraft Black Liquor
Authors: Sharma Manorma , Simões André , Alves Patrícia , Gando- Ferreira Licínio M.
Published: August 2022

Black liquor (BL) from kraft pulping industries contains a large fraction of lignin and hemicelluloses and their efficient separation can open up new possibilities for integrated biorefineries. In this work, lignin and hemicelluloses were separated from BL and concentrated BL (obtained by ultrafiltration), by precipitation using acidification and antisolvent precipitation method, respectively. For lignin precipitation, different organic acids, namely acetic, lactic and citric acid, were used and the yield and purity of the extracted lignin were compared with the lignin precipitated using inorganic acids, namely sulphuric and phosphoric acid. Among the organic acids, the highest yield of lignin (57.2%) was obtained by lactic acid, but the extract also contained the highest levels of inorganic impurities (9.2%). The extract obtained from acetic acid contained lower inorganic impurities and the lignin yield was 48.1%. The hemicellulose was extracted from BL liquor that was concentrated using the ZnObased PES mixed matrix ultrafiltration membrane, which was started by first separating lignin (at pH 3.5, 4 and 4.5) from it. The supernatants from the lignin precipitation process were used as a source of hemicellulose and this was precipitated by using acetone as an antisolvent. The highest hemicellulose yield (54.4%) was obtained from the supernatant with the lowest lignin content and highest acetone to supernatant ratio.

Authors: Mouro Cláudia , Fangueiro Raul , Gouveia Isabel
Published: August 2022

Composite wound dressings which combine the suitable properties of distinct materials into one dressing are currently being explored, in combination with different types of bioactive compounds, to enhance the healing process and avoid skin infections. In the present work, poly(vinyl alcohol) and chitosan nanofibers containing Agrimonia eupatoria L. were fabricated using a needleless electrospinning method (through Nanospider technology) and deposited on top of a 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized cotton textile dressing. The negatively charged carboxyl groups on the cotton fibers interacted with the positively charged amino groups of chitosan, which was previously blended with poly(vinyl alcohol) and Agrimonia eupatoria L. to produce the nanofiber layer. The properties of the produced composite materials were analyzed to determine the dressing’s potential for antimicrobial wound dressing applications.

Authors: Baptista Cecília , Santos Luís , Emília Amaral Maria , Silva Lúcia
Published: August 2022

Essential oils (EOs) are acclaimed for their antimicrobial properties, leading to their multiple applications in various fields. In this work, four aromatic plants were used, namely thyme (Thymus mastichina L.), everlasting (Helychrysum stoechas Moench), European pennyroyal (Mentha pulegium L.) and fennel (Foeniculum vulgare Mill.). Hydrodistillation was the extraction method used, and the obtained extracts were composed of a variety of volatile molecules, mainly terpenoids and phenylpropenoids. The EO yields were determined, and the chemical composition of these natural products was obtained by gas chromatography-mass spectrometry (GC-MS) analysis. The yields varied greatly in the range of 0.99 to 4.27% (v/w). The two major chemical constituents of the EOs analysed by GC-MS were as follows: thyme – 1,8-cineole and champhor; everlasting – α-pinene and limonene; European pennyroyal – pulegone and isomenthone; fennel – trans-anethole and limonene. This preliminary study is an important contribution to the understanding of EO bioactive compounds that are under investigation to establish their ability to control the biocolonization of cultural heritage.

Authors: Almeida Adelaide , Oliveira Júlio , Matias Flávia , Ribeiro Carlos , Silveira Daniele , Tavares Jorge
Published: August 2022

This work evaluated caffeine removal in a vertical flow constructed wetland (VFCW), planted with Vetiveria zizanioides. The feeding was continuous (synthetic influent: mineral medium and caffeine) to reduce the concentration variations in the bed. Two influent concentrations (0.75 ± 1.0 mg·L−1 and 1.5 ± 1.0 mg·L−1) were used with a constant hydraulic load (100 ± 10 L·m−2·d−1). Plant growth was monitored weekly, and characterization was carried out to determine the levels of chlorophyll a and b, pigments and carotenoids, and nutrients (nitrogen, phosphorus, magnesium, calcium, sodium and potassium). HPLC-MS was used to determine the caffeine concentration. The caffeine removal efficiency reached averages of 93 ± 1% and 87 ± 1% (retention time: 6.23 ± 0.23 hours). The caffeine contents in the influent did not affect chlorophyll a, total chlorophyll or carotenoids, and an increasing trend throughout the tests was observed. Sodium and potassium contents also showed an increase with higher caffeine concentration. This preliminary study showed that removing caffeine from wastewater using a VFCW is promising.

Water Reuse in a Municipal Sports Center
Authors: Silva Flora , Maria Antão-Geraldes Ana , Albuquerque António
Published: August 2022

Two potential measures for increasing water use efficiency in a municipal sports center were evaluated: (1) the reuse of water originating from showers in the flushing toilets in the indoor football court building; and (2) the reuse of water from swimming pool filter backwashing for irrigation. In the indoor football court building the total annual water consumption is around 3,500.5 m3 and from the showers is approximately 1,785.26 m3. Therefore, the greywater generated in showers can be reused in toilet flushing, which consumes about 840.12 m3 per year. The estimated annual water consumption for filter backwashing is 4,197.6 m3. The annual amount of water necessary for irrigating the lawn of the local football stadium is around 7,200 m³. Thus, the filter backwashed water, after being subjected to a sedimentation process, could be fully reused for this purpose.

Authors: Skliar Iryna , Marchenko Tetiana , Komarov Sergii , Matsko Vitalii , Pavlishena Liudmyla , Shapoval Mariana
Published: August 2022

The article offers an overview on the most notable features of the implementation of psychonarratives in fiction and documentary and fiction prose about the Anti-terrorist Operation (ATO) and the hybrid warfare in Donbas from the standpoint of the achievements of modern humanities, which gives intelligence a multidisciplinary nature. The degree of academic research on the outlined topics at both the world and the national scientific levels has been clarified. The contribution of the Western scientists to the development of theoretical and methodological principles of parameterization of psychonarratives is outlined. There is a tendency to increase the interest of domestic specialists in narratology, in particular psychonaratology, mainly in empirical terms. At the same time, an objective lack of thorough theoretical developments of the monographic or dissertation level on the outlined issues has been stated in Ukrainian studies. Terminological vagueness and imbalance in the interpretation of the key concepts of psychonarrative studies have been recorded. Methods and means of realization and manifestation of the psychonarratives in the text structures are established. There is a growing interest of domestic researchers in the direct or indirect consideration of narrative, psychonarrative and selfnarrative in fiction prose and documentary and fiction prose about the ATO and the hybrid warfare in the Donbas in the context of discursivity and intermediality. The peculiarities of psychonarrative expression on the formal structure and sence-content levels are indicated. The common and distinctive features of the realization of psychonarratives in fiction and non-fiction literature are briefly noted.

The specificity of the process of professional training and formation of future teachers of fine arts is due to the direction of art and pedagogical education, the peculiarities of communication with art, approaches to the use of its educational potential. Therefore, in determination of the principles of professional development of teachers of fine arts, the problem of theoretical and methodological understanding of the nature and content of decorative and applied arts in the preparation and professional development is actualized.  On the one hand, this applies to how the artistic and aesthetic consciousness of the future teacher will be formed, and on the other - on what basis this teacher will educate his or her students. In accordance with the theoretical aspect of the formation of artistic and pedagogical competence of future teachers of fine arts in the process of studying of decorative and applied arts, a research was conducted. It made it possible to analyze the content, forms, methods and conditions of formation of artistic and pedagogical competence of future artists-teachers. Diagnostic research tools have been developed, which make it possible to identify the level of formation of the main structural components of artistic and pedagogical competence of future teachers of fine arts. The research showed an insufficient level of formation of artistic and pedagogical competence of future teachers of fine arts, which is characterized by a lack of thoroughness and systemness of knowledge in decorative and applied arts, by insufficient development of the emotional and sensual sphere of students and reproductive readiness for professional and creative activities.

Examination of mucociliary clearance (MCC), evaluation of options for operative access to the maxillary sinus, from the position of MCC, regarding foreign bodies, are of increasing interest in otorhinolaryngology due to the ever-increasing incidence of this pathology, its artificial (secondary) nature—that is, arising against the background of known absence of any initial pathological changes. Objective. To study the local function of the MCC of the middle nasal passage in the postoperative period in patients with foreign bodies of the maxillary sinuses with various methods of surgical intervention on the maxillary sinus. Methods. The study involved 60 patients with foreign bodies of the maxillary sinuses and a comparison group of 60 healthy individuals. The patients were divided into 2 groups of 30 people according to the type of surgical access—trocar endoscopic maxillary sinusotomy, endonasal endoscopic antrostomy. The subjects underwent computed tomography (CT). For examination of local MCC, modern methods of mathematical analysis of data from high-speed video filming of a ciliary epithelium preparation were used. A questionnaire was used to subjectively assess nasal symptoms. The examinations were conducted in the early (1–14 days), late (1–6 months) postoperative period. Results. It was revealed that the normative local value of the MCC of the middle meatus in healthy individuals is 11,76 ± 3,01 Hz. In patients with foreign bodies of the maxillary sinus, the greatest influence on the initial local MCC, its violation in the postoperative period is exerted by changes in the middle meatus, cells of the ethmoid labyrinth, and mycetoma. The values of the local MCC of the middle meatus depend on the access to the maxillary sinus. Conclusion. Using methods for assessing local MCC, it is necessary to optimize access to the maxillary sinus with a wider use of techniques that do not affect the key area of the osteomeatal complex (transmaxillary endoscopic approach, access through the lower meatus).
Flexible Average Inflation Targeting: How Much Is U.S. Monetary Policy Changing?
Authors: Coulter Jarod , Duncan Roberto , Martínez-García Enrique
Published: August 2022

One major outcome of the Federal Reserve’s 2019–20 framework review was the adoption of a Flexible Average Inflation Targeting (FAIT) strategy in August 2020. Using synthetic control methods, we document that U.S. inflation rose post-FAIT considerably more than predicted had the strategy not changed (an average of 1.18 percentage points during 2020:M8–2022:M2). To explore the extent to which targeting average inflation delayed the Fed’s response and contributed to post-FAIT inflation, we adopt a version of the open-economy New Keynesian model in Martínez-García (2021) and document the economic consequences of adopting alternative measures of average inflation as policy objectives. We document three additional major findings using this general equilibrium setup: First, depending on how far back and how much weight is assigned to past inflation misses, the policy outcomes under FAIT are similar to those under the pre-FAIT regime. Secondly, we find that the implementation of FAIT can have large effects over short periods of time as it tends to delay action. However, over longer periods of time—such as the 1984:Q1–2019:Q4 pre-FAIT period—its effects wash out and appear negligible. Finally, we find that di˙erent average inflation measures explain an average of 0.5 percentage points per quarter of the post-FAIT inflation surge, indicating that targeting average inflation by itself can only explain part of the inflation spike since August 2020.

O, dicho de otra manera: ¿cómo tratar a un acreedor que pretende votar en una Junta de Acreedores sabiendo que lo que vaya a perder en el concurso lo va a ganar, incluso con creces, por otro?.Las preguntas anteriormente expuestas son solo algunas de las interrogantes que resuelven los autores, a través del presente artículo, el mismo que partiendo de un interesante caso, ofrece al lector un análisis claro referido al conflicto de interés de los acreedores concursales en el marco de las juntas de acreedores en materia concursal.Como se podrá observar a lo largo del texto, en opinión del autor, ante la falta de regulación expresa sobre este tema en nuestra Ley General del Sistema Concursal, son trasladables las limitaciones estatutarias o aquellas establecidas en la Ley General de Sociedades sobre conflictos de interés. En ese sentido, el autor sugiere como alternativa que se someta a consideración de la Junta de Acreedores la suspensión del derecho de voto del acreedor conflictuado. Sin embargo, más allá de la solución que se construye, resulta urgente e importante que se trabaje una modificación a la Ley General del Sistema Concursal a fin de tratar este asunto.

El entendimiento de los derechos de las personas con discapacidad se ha visto modificado por la adopción e implementación de la Convención sobre los Derechos de las Personas con Discapacidad. Entre los cambios necesarios para su implementación, resalta el referido a la capacidad jurídica (o capacidad de ejercicio) de las personas con discapacidad. A contracorriente con lo que se registra en la mayor parte de Códigos Civiles de la región, la Convención reconoce que las personas con discapacidad sí pueden tomar decisiones y que su discapacidad no puede ser motivo para privarlos de ese derecho. Para garantizar esto, es necesario que los Estados reconozcan apoyos para la capacidad jurídica que sean vigilados por salvaguardias que eviten abusos, influencia indebida y conflictos de intereses. Este artículo presenta los diferentes debates que se han sucedido a nivel doctrinario con respecto a estas nuevas instituciones que obligan a repensar diversas categorías jurídicas como el acto jurídico y sus causales de anulabilidad y nulidad; el consentimiento informado; o la inimputabilidad.

La tecnología de la cadena de bloques, según estimaciones, cambiará la forma en que se desarrolla el intercambio de bienes y oferta de servicios, la gestión de conflictos, e influirá sustancialmente en el proceso de modernización del Estado. La investigación actual pretende ser una guía teórica organizacional y sencilla que brinde una estratégica para el proceso de gestión de conflictos en el ámbito estatal. Esta, basada en la necesidad imperiosa de la modernización del sistema público actual, basado en la división de poderes. Este artículo, resalta fundamentalmente tres ideas concordantes: primero, que la tecnología de la cadena de bloques ayuda a automatizar ciertas labores, en consecuencia, facilita el acceso a un espacio descentralizado independiente de una autoridad central de control, democratiza y transparenta procesos de gestión y tomas de decisión permitiendo la examinación de todos los intervinientes en un plano de igualdad, y tercero, pretende la mantención de la intervención manual necesaria por parte del Estado, para concentrar sus labores en tareas complejas, procurando al sostenimiento esencial de su status quo, dejando de esta forma, labores meramente administrativas en manos de la tecnología.

The importance of gamification in education is supported by the studies conducted. It is very important to teach our students to use technology effectively during the trainings. Technology is just as important in teaching one to use it in the right direction. This study aimed to determine the current situation in the research process and the opinions of teachers and students in its implementation. The main purpose of the research is to determine the importance of game technology in primary schools affiliated to the state institution. In order to achieve the purpose of this study, interviews were conducted with 32 students and 4 teachers. The universe was selected on a voluntary basis. Research questions were created by taking the expert opinions from the researcher. The findings obtained from the research were explained using the content analysis method by thematisation. It has been concluded that students and teachers have positive opinions about game technology. It has been concluded that they want to use game technology in all courses. They noted that students and teachers sometimes have problems caused by a lack of information in a negative way. In this case, it can be corrected with in-service trainings being given.

Published: August 2022

Since mid-2020, mostly caused by the Covid-19 outbreak which forced almost all academic activities involving massive participants to be cancelled due to health and safety reasons, the webinar suddenly became a very famous activity among learners. Therefore, this study aims to investigate the learners’ experience and perspective in this type of academic interaction, especially in Arabic webinar activity. Since this kind of interaction has become an upward trend that is applied massively by almost all institutions, observing it through a cross-sectional survey could be significant research. Thus, we use mixed (quantitative and qualitative-descriptive) methods to explore not only the perspectives of the participants but also to describe their experiences. It starts by providing data from survey results, classifying, analyzing, and presenting the analysis. Based on the recorded learners’ experience, it can be noticed that the Arabic webinars held by various Arabic language academies and institutions across the world were considered quite effective and efficient. Even though there are still many obstacles and shortcomings, especially from a technical point of view, this kind of web-based seminar can be one of the promising alternatives for Arabic learning when the Covid-19 pandemic is still ongoing. Most of the participants were satisfied with the performance of the Arabic language webinars they have participated in, indicated by a high score in the general assessment.

Antioxidants are compounds that can inhibit or slow down oxidative damage due to free radicals. Torch ginger flower (also known as kecombrang flower in Indonesia) essential oil has antioxidant activity values ranging from 61.61-83.17%. This study aim to determine the best concentration of torch ginger flower essential oil (Etlingera elatior) in cookies and to improve the chemical and microbiological qualities of cookies. Torch ginger flowers are cut into pieces and then distilled. The stage of adding torch ginger flowers essential oil was carried out according to the experimental design namely P (100: 0), Q (100: 0.1), R (100: 0.2), S (100: 0.3). The observation parameters in this study were proximate, antioxidant activity, and microbiological (total plate count) parameters. Data processing was carried out in a completely randomized design (CRD) based on data from observations of the test parameters with three repetitions. The result of study showed that the cookies with the addition of torch ginger flower essential oil had moisture content of 4.50-5.11%, ash content of 0.80-1.05%, fat content of 20.68-22.45%, protein content of 6.88-7.95%, carbohydrate content of 63.85-65.30%, antioxidant activity of 55.45-70.78%, the total plate count (bacteria, mold, and yeast) about <10 colonies/g.

Edible rice paper is used for making fresh summer rolls (salad rolls) or fried spring rolls in Vietnamese cuisine, where the rice paper is called bánh tráng or bánh đa nem. Ingredients of the food rice paper include white rice flour, tapioca flour, salt, and water. However, in this study, watermelon albedo pectin flour was added to the formulation. The purpose of this study was to determine the concentration of pectin flour and the effect of watermelon albedo pectin addition on the physicochemical characteristics of rice paper. The addition of pectin flour can produce a product that is elastic, not easily torn, and translucent. The research method used a completely randomized design (CRD) with the research factor being the concentration of watermelon albedo pectin flour which consisted of 6 experimental levels and 4 replications. The concentrations of pectin used were 0.25%, 0.5%, 0.75%, 1%, 1.25%, and 1.5%. Data were analyzed using ANOVA (analysis of variance) and continued with duncan multiple range test (DMRT) at the level of 5%. The variables tested were water content, water activity and rehydration power. Based on the results of this study the addition of watermelon albedo pectin flour on rice paper as much as 1.25% was the best treatment, this was because the water content produced about 11.38% and the rehydration power about 233.27%. There was an increase in water content and water activity, but a decrease in rehydration power, however, the water content test showed that the pectin concentration had no significant effect on the physicochemical characteristics of rice paper. So that the concentration of watermelon albedo pectin only affects the water activity and rehydration power of rice paper.
