Authors: Romo-Rojas Mario Giovanni , Romo Estefanía Calero
Published: June 2022

El objetivo de la investigación fue determinar la degradación de la vegetación de páramo por efecto de la ganadería en el Parque Nacional Llanganates. Se establecieron dos zonas de páramo con características similares en los Complejos Lacustres Anteojos y Pisayambo. Con el uso del programa QGIS y shapefile a escala 1: 50000 se delimitaron los sitios con presencia y ausencia de ganado. Mediante la observación directa se contabilizó la cantidad de ganado que recorre Pisayambo, los hatos fueron registradas y georreferenciadas en una ficha de campo. El estudio vegetativo se realizó aplicando la técnica de áreas mínimas, en cada zona de estudio se tomaron tres unidades muestrales. En el instrumento de investigación se anotó el nombre de las especies, frecuencia, escala de presencia y estatus según los criterios señalados en literatura consultada. Los resultados evidencian que en los alrededores del Complejo Lacustre Pisayambo existe la presencia de 109 ejemplares de ganado vacuno y 12 de caballar. La mayor dominancia de especies vegetales se encuentra en el Complejo Lacustre Anteojos, esto se refleja en el valor calculado del Índice de Diversidad de Simpson (0,901) en comparación del obtenido en Pisayambo (0,860). Las especies resistentes a la presencia de ganado son Calamagrostis intermedia, Lachemilla orbiculata y Plantago rigida. Se concluye que, el ganado produce un impacto negativo en la vegetación de páramo y a la vez constituye un serio problema para el manejo del Parque Nacional Llanganates.

Na produção de hortaliças um dos fatores importantes em sua produção é o ambiente de cultivo, que influencia na produtividade, entre as variedades e épocas de cultivo. O objetivo do trabalho foi avaliar a produção, temperatura foliar e temperatura do solo de duas variedades de alface (verde lisa e roxa crespa) em função das variáveis ambientais em dois ambientes (campo e estufa). O delineamento utilizado foi o inteiramente casualizado em esquema fatorial 2 x 2 (2 variedades e 2 ambientes), com seis repetições. Onde a partir das imagens termográficas foi registrada similaridade quanto à temperatura do solo entre os ambientes, não interferindo no desempenho das raízes das variedades cultivadas. A temperatura foliar foi superior para variedade crespa roxa. Constatou-se, portanto, que a estufa proporcionou melhores condições ao desenvolvimento das variedades da alface, observando-se, nos dois ambientes, melhor desempenho da alface da variedade verde lisa.

A cajucultura é uma atividade que tem se destacado na região semiárida do Nordeste brasileiro pela geração de emprego e renda. Entretanto, nessa região a produção agrícola tem sido afetada pelo excesso de sais da água e do solo. Sendo assim, é de grande relevância a busca de estratégias que diminuam os problemas ocasionados pela salinidade no cultivo de cajueiro, sendo a adubação orgânica uma alternativa promissora. Diante disso, objetivou-se com esse trabalho avaliar o crescimento do cajueiro anão precoce ‘BRS 226 Planalto’ sob irrigação com água salina e adubação com esterco bovino. O experimento foi conduzido em lisímetros de drenagem, em casa de vegetação. O delineamento experimental utilizado foi o de blocos casualizados, em esquema fatorial 5 × 4 com três repetições, sendo cinco níveis de condutividade elétrica da água de irrigação (0,7; 1,4; 2,1; 2,8 e 3,5 dS m-1) e quatro doses de adubação com esterco bovino (2,5; 3,5; 4,5 e 5,5% em base no volume de solo). O crescimento do cajueiro anão precoce foi mensurado pelo diâmetro do caule do porta-enxerto e do enxerto, a altura de plantas, a área foliar e o número de folhas, aos 122 dias após o transplantio. A salinidade da água de irrigação a partir de 0,7 dS m-1 inibiu o crescimento inicial do cajueiro anão precoce ‘BRS 226 Planalto’, aos 122 dias após o transplantio. A adubação com doses elevadas de esterco bovino diminuiu as variáveis de crescimento do cajueiro anão precoce ‘BRS 226 Planalto’.

Authors: Bogoriani N W , Atmaja V A D , Ratnayani O , Wirajana I N
Published: June 2022

The Balinese plant andong (Cordyline terminalis Kunth) has anti-inflammatory properties. The focus of this research was to determine whether andong leaf extract has anti-inflammatory properties and is effective against carrageenan-induced edema in rat soles. In this study, carrageenan was used to induce inflammation in the soles of Wistar rats. 25 rats were divided into five treatment groups. Group I was given aquadest as the control; group II was given diclofenac sodium at a dose of 4.5 mg/kgbw as a drug control; and groups III, IV and V were given ethanol extract of andong leaves at doses of 150 mg/kgbw, 300 mg/kgbw, and 600 mg/kgbw orally as test groups. For six hours, the inflammation volume was measured using a plethymometer. One-way ANOVA was used to test differences between the treatment groups. The results showed that the ethanol extract of andong leaves had the highest anti-inflammatory activity in the six-hour period when given at doses of 150 mg/kgbw (36.35% 0.02), 300 mg/kgbw (26.30% 0.20), and 600 mg/kgbw (20.67% 0.16) with a significant difference (p < 0.05) compared to the negative control (86.84% 0.092), but this was not significantly different from the positive control (22.21% 0.01). Based on these findings, it can be concluded that a dose of 600 mg/kgbw is the most effective in reducing inflammation.

Utilization of Rhizosphere Earthworm Extracts to Support the Immune System
Authors: Dharmawati IGA Ayu , Sukrama I Dewa Made , Thahir Hasanuddin , Manuaba Ida Bagus Putra
Published: June 2022

Periodontitis is an inflammatory condition caused by periodontal bacteria that are recognized by Toll-like receptors on neutrophils, macrophages, and other immune cells. As a result of this interaction, immune cells produce inflammatory molecules like cytokines and chemokines. In addition to the pathogenic effects of periodontitis, dysregulation of neutrophil activity can occur. The neutrophil acts as a double-edged sword in periodontitis, mobilizing defence mediators and tissue repair mechanisms while also causing further tissue damage. The goal of this study was to determine how Lumbricus luberus worm extract (EEW) affected the number of neutrophil cells in rats with periodontitis. A post-test design was used. Five Wistar rats, each infected with P. gingivalis, were divided into groups: a control group (no earthworm extract), an oral EEW (200 mg/kg/body weight) group, and a topical EEW gel group (20%). The number of neutrophil cells was measured on days 3, 7, 14, and 21. The study was carried out at the Udayana University Analytical Laboratory and the Veterinary Medicine Laboratory. The differences between control, oral, and topical Lumbricus rubellus extract administration on days 3 and 7 were significant (p < 0.05). On days 14 and 21, there was a significant difference (p < 0.05) between the control vs. oral administration groups and between the control vs. earthworm extract gel groups. However, on days 14 and 21, there was no significant difference between the oral administration and L. rubellus gel extract groups (p > 0.05). The number of neutrophils was significantly lower following the oral administration of L. rubellus earthworm extracts.

Published: June 2022

Gyrinops versteegii leaves are high in flavonoids, which have a variety of biological and pharmacological properties. The focus of this research was to determine the antioxidant and antibacterial activity of flavonoids in Gyrinops versteegii leaf water extracts. In this study, extraction was by maceration and partitioning, separation and purification was by chromatography, identification of compounds was carried out using UV-Vis and FTIR spectrophotometers, and antioxidant activity was measured with the DPPH method and antibacterial activity with the diffusion disc method. Flavonoids were thereby isolated. The ethyl acetate extract had the highest total flavonoid content, with 186.976 mg QE/100 g. With inhibition zone diameters of 19 and 13 mm, ethyl acetate extract was the strongest extract in inhibiting the growth of S. aureus and E. coli in the antibacterial activity test. Flavonoids were identified as flavonols after isolation, phytochemical screening, and UV-Visible and FTIR spectroscopic identification. The isolated flavonols had potent antioxidant activity (IC50 = 60.27 ppm) as well as potent antibacterial activity (inhibition zone diameters of 33.82 mm for S. aureus and 23.22 mm for E. coli). The findings therefore showed that tea made from Gyrinops versteegi leaves contains the flavonoid flavonol, which has antibacterial and antioxidant properties.

Authors: Ratnayani Ketut , Ratnayani Oka , Pane Indra Alexio
Published: June 2022

Okara (tofu dregs) is a soybean waste product from the tofu and soymilk processing industry. To create a useful product, the remaining protein content in okara must be used. The goal of this study was to determine the enzyme-substrate (E/S) ratio capable of producing the highest antioxidant activity from okara protein hydrolysate, as well as the amino acid composition of such a protein hydrolysate (especially the amino acid potential as antioxidants). To produce protein concentrate, the protein of okara was isolated using an alkaline extraction method followed by isoelectric precipitation. The protein concentrate was then hydrolyzed for six hours with papain enzyme at 50-55 °C and pH 7, with E/S ratios of 3%, 4%, 5%, 6%, and 7%. Using the DPPH method, the antioxidant activity of the obtained okara protein hydrolysate was determined. The HPLC method was used to determine the amino acid composition of the protein hydrolysate. The E/S ratio of 4% had the highest antioxidant activity (98.86%); the composition of amino acids L-Phenylalanine, L-Isoleucine, L-Valine, L-Glycine, L-Lysine, L-Tyrosine, L-Proline, L-Histidine, L-Cysteine and L-Methionine potentially contributed to the antioxidant activity effect. These findings suggest that okara protein hydrolysate has the potential to be used as an antioxidant-rich food ingredient.

Turmeric and tamarind are medicinal plants that have a variety of health benefits, including laxative, antibacterial, anticancer, and hepatoprotective properties. The focus of this research was to look at the histology of the liver and the levels of SGPT-SGOT in broilers fed turmeric-tamarind extracts water at a rate of 2%. This study used a completely randomized design, with treatment options including a control, a mixture of turmeric rhizome and tamarind fruit (2%), and concentrations of 2% turmeric rhizome and 2% tamarind. The turmeric rhizome and tamarind extracts treatment was given in drinking water ad libitum. Quantitative data from the study were analyzed statistically, and if there was a significant effect, Duncan’s test was used; qualitative data were presented with descriptions and images. The blood levels of SGPT in the control broilers were higher than in the broilers exposed to any of the other treatments. Also, in the control broiler livers, hydrofic degeneration, nucleus pyknosis, and congestion were higher than in the treatment group broilers, but these were still within normal limits. Water supplementation with a mixture of turmeric rhizome and tamarind fruit extracts did not have a negative effect on the performance of the broiler livers.

Published: June 2022

The ability of a plant growth-promoting bacteria (PGPB) strain to colonize the roots and tissues of inoculated plants is important for their successful use in agricultural practices. The purpose of this study was to determine how effective 15 indigenous halotolerant PGPB were at colonizing three different agronomic crops via seed inoculation. Using standard Hoagland’s media and Hoagland’s media amended with 100 mM NaCl, we tested 15 gfp-tagged halotolerant bacterial isolates for their ability to colonize rice, maize, and soybean seedlings. The quantitative dilution plating method and fluorescent microscopy were used to determine the colonization degree of gfp-tagged halotolerant PGPB isolates in the rhizoplane zone and in the inner tissue of the seedlings at 21 days after germination. All halotolerant PGPB isolates colonized the rhizoplane zone of all seedlings. In both standard and 100 mM NaCl amended Hoagland’s media, isolates E194-3, D183-4, and E101-1 showed the highest colonization in rice, maize, and soybean seedlings, respectively. The ability of halotolerant PGPB isolates to colonize agronomic crops was found to vary depending on bacterial isolates, plant species, plant tissues, and NaCl concentration.

Published: June 2022

Sustainable agriculture can be used to achieve food security by continuously producing agriculture while taking safety, soil health, and environmental and economic considerations into account. Reduced agricultural land for agricultural production could stifle the growth of sustainable agriculture. This study made use of biochar, which is made from organic waste and serves to temporarily hold soil nutrients in the root zone of plants. The focus of this research was to find new ways to expand coastal land use by using biochar made from organic waste as a soil amendment for agriculture, particularly vegetable production. The study employed a two-factor design: the first was the size of the biochar material, which was coarse and fine, and the second was the biochar dosage, which included 10, 15 and 20 tons per hectare. Coconut shell waste was used to make the biochar. According to the results, the application of course-sized biochar at a dose of 15 tons per hectare resulted in lateral root distribution. Vegetable root development tended to be reduced when fine biochar was used. We can conclude that one of the solutions for sustainable agricultural production is to use biochar ameliorant materials made from environmentally friendly organic waste.

Published: June 2022

Acacia crassicarpa seedlings face challenges with growth and health. Xanthomonas leaf blight, Fusarium wilt, and leaf spots caused by Pestalotiopsis or Phaeotrichoconis are all major nursery diseases of A. crassicarpa. This study was carried out to consider solutions for improving seedling conditions. The growth and health of A. crassicarpa seedlings were assessed using two commercial products: an organic biofertilizer (LOB-BS) and an organic multipurpose fertilizer (OMF). The LOB-BS + basal fertilizer (BF) treatment led to a higher germination rate than the other treatments, according to our findings. Similarly, at 12 weeks after sowing, the same treatment produced the tallest A. crassicarpa seedlings. In comparison to other treatments, the incidence of Xanthomonas leaf blight, Fusarium wilt, and leaf spot diseases was lower in the plots of OMF and OMF + BF treatments. Based on these findings, the LOB-BS product could be used to improve the growth of A. crassicarpa seedlings, while the MOF product could be used to reduce the incidence of major A. crassicarpa seedling diseases in the nursery.
Keywords: Fusarium, leaf spot, Xanthomonas, organic biofertilizer (LOB-BS), organic multipurpose fertilizer (OMF).

Published: June 2022

Fusarium solani is a pathogen that causes dragon fruit stem rot. Phenolic compounds are thought to slow the progression of the disease. The aim of this research was to determine the quantity of phenolic compounds in Samanea saman leaf extract, identify the phenolic compounds, and evaluate their antifungal activity against F. solani. Extraction was done by maceration with 96% ethanol, followed by fractionation. Total phenolic content was determined by UV-Vis spectroscopy. Purification was performed by chromatographic technique. The isolate was identified by phytochemical test and spectroscopy technique. Antifungal assay was carried out by well diffusion agar. The total phenolic content of the acetone extract was 6589.12 mg GAE/100g extract. The extract strongly inhibited the growth of the pathogenic fungi with an inhibitory zone of 25.50 mm. The active isolate strongly inhibited the growth of F. solani with an inhibition zone of 35.50 mm. The phytochemical test and UV-Vis spectroscopy analysis showed that the isolate was hydrolyzed tannin, which absorbs ultraviolet light with a wavelength of 264.90 nm. The infrared spectroscopy analysis showed that the functional groups of tannin are OH (phenol), -CH aliphatic, -C=O, -C=C aromatic, and -CO.

Published: June 2022

The tomato (Lycopersicum esculentum Mill.) has substantial scope for development due to its high economic value and large export potential. Ralstonia syzygii subsp. Indonesiensis (RSI) is the cause of bacterial wilt disease which attacks the vascular system in Solanaceae. It can cause large losses in yield and has caused global concern because of its widespread distribution and attack on many important crops. The aim of this research was to identifiy and characterize the ability of indigenous rhizobacterial isolates to control RSI and promote tomato growth. The PGPR traits studied were production of hydrogen cyanide, siderophores, biosurfactant, and ammonia, and protease activity. Bacterial identification was performed using 16S rRNA. Our findings revealed that the strains identified shared some similarities with Bacillus thuringiensis strain ATCC 10792 (IR.2.3.5), B. mycoides strain ATCC 6462 (IR.1.3.4), Bacillus thuringiensis strain IAM 12077 (IR.2.2. 1), Serratia ficaria strain DSM 4569 (IR.3.1.4), Enterobacter oryzendophyticus strain REICA_082 (IR.2.2.7), Cronobacter dublinensis subsp. lausannensis strain E515 (IR.2.2.5) and S. rubidaea strain DSM 4480 (IR.2.2.6). All of the isolates were tested for a variety of abilities related to growth promotion and biocontrol.

Nursery productivity is an important factor in plantation forest sustainability. Seedling quality contributes significantly to plantation health. Fertilization regimes and pest and disease control are critical. However, environmental concerns have arisen as a result of the use of chemical fertilizers and pesticides. The ideal is to manage nurseries in an environmentally friendly manner while maintaining productivity. The utilization of plant growth-promoting microbes (PGPM) is seen as one option in this effort. It has been demonstrated elsewhere that arbuscular mycorrhizae (AM) can improve the growth and health of host plants. In this study, the effect of two AM products on the growth and health of Eucalyptus pellita seedlings in reduced fertilizer regimes was investigated. The results showed that the AM products were unable to compensate for reduced fertilizer regimes (both to 50% and 25%), in terms of seedling height and diameter, in E. pellita. Further research is needed to determine whether using AM products can reduce the need for fertilizers and/or pesticides.

In an attempt to provide regionalized information about maize genotypes’ response to corn stunt disease complex, this study evaluated the corn stunt disease severity and productivity of conventional (7) and transgenic (11) maize genotypes under natural infestation of its insect vector, Dalbulus maidis (Hemiptera: Cicadellidae). The work was carried out in Campos Novos, SC, Brazil, during the 2020/2021 crop season. In a randomized block design, the genotypes were sowed in experimental plots of 14 m2 , with four replicates (plot) per genotype. At 90 days after sowing, the severity of corn stunt disease was analyzed using a visual symptoms scale, while the maize productivity was assessed at physiological maturation. There was variability for response to stunt disease in the genotypes and a negative correlation between severity and grain yield. Among the conventional genotypes, P3456, FS055, SCS154 Fortuna, SCS156 Colorado, and SCS155 Catarina had lower severity of corn stunt disease. For the transgenic genotypes, AS1757 PRO3 and P3551 PWU were more resistant, while B2418 VYHR, AG9025 PRO3, and P1225 VYHR had high corn stunt disease severity. The corn stunt severity varied from 1 (absence of symptoms) in P3551 PWU to 4.8 (more than 75% of leaves with symptoms) in P1225 VYHR, while the lowest and highest yields were obtained for BG7056 (1,253.7 kg.ha-1) and P3016 VYHR (9,794.6 kg.ha-1), respectively. The genotypes with low corn stunt disease severity are suitable options for sowing in the Midwest region of Santa Catarina, Brazil, in conditions of high population pressure of D. maidis.

Published: June 2022

ABSTRACT
 
Tilapia gonads mature quickly before reaching market size, caused by a diverting of feed energy from growth to reproduction. As a result, somatic growth is disrupted to achieve market size, the operational costs are high, and the rearing period is longer. This study aims to evaluate the ability of karamunting leaf extracts to inhibit the development of tilapia gonads. This study used a complete randomized design with four treatments and three replications, namely 0 mg/kg, 25 mg/kg, 50 mg/kg, and 100 mg/kg of karamunting leaf extract. Tilapia fish weighed 13–14 g were kept in an aquarium measuring 100×60×50 cm with a stocking density of 20 fish/ aquarium. Fish were fed twice a day at 8 a.m and 5 p.m in at satiation. Sampling was carried out at the beginning of the study, on day 30th and day 60th. On day 30th the result showed that the best dose in inhibiting the development of fish gonad was 100 mg/kg of karamunting leaf extract that was 1.15 ± 0.19% and the daily growth rate was increased at 2.22 ± 0.06%. On day 60th, the best dose in inhibiting gonad development was 25 mg/kg of karamunting leaf extract, which was 2.49 ± 1.24% and the daily growth rate was increased amount 3.26 ± 0.06%.

ABSTRAK
 
Gonad ikan nila cepat berkembang sebelum mencapai ukuran pasar, menyebabkan pengalihan energi pakan dari pertumbuhan ke reproduksi. Akibatnya, pertumbuhan somatik terganggu sehingga untuk mencapai ukuran pasar biaya operasional tinggi dan masa pemeliharaan lebih lama. Penelitian ini bertujuan untuk mengevaluasi ekstrak daun karamunting dalam menghambat perkembangan gonad ikan nila. Penelitian ini menggunakan rancangan acak lengkap dengan empat perlakuan dan tiga ulangan; yaitu 0 mg/kg, 25 mg/kg, 50 mg/kg, dan 100 mg/kg ekstrak daun karamunting. Ikan nila berukuran 13–14 g dipelihara di akuarium berukuran 100×60×50 cm dengan padat tebar 20 ikan/akuarium. Ikan diberi makan dua kali sehari pada jam 8 pagi dan 5 sore dengan at satiation. Pengambilan sampel dilakukan pada awal penelitian, hari ke-30 dan hari ke-60. Hasil pada hari ke-30 menunjukan bahwa dosis terbaik dalam menghambat perkembangan gonad pada ikan uji adalah 100 mg/kg ekstrak daun karamunting yaitu 1.15 ± 0.19% dan meningkatkan pertumbuhan harian 2.22 ± 0.06%. Pada hari ke-60 dosis terbaik dalam menghambat perkembangan gonad adalah 25 mg/kg ekstrak daun karamunting yaitu 2.49 ± 1.24% dan  meningkatkan pertumbuhan harian 3.26 ± 0.06%.

Katuk leaves [Sauropus androgynus (L.) Merr] and moringa leaves (Moringa oleifera Lam.) are plants that can be used as galactagogues. Galactagogues compounds in both can stimulate the hormones prolactin and oxytocin, thereby increasing milk production. Katuk leaves and moringa leaves have a natural taste that is not favoured so that processing and formulation of other ingredients are needed to make the two ingredients more preferable. With an average growth from 2016-2020 of 4.250%, cookies can be a medium to help meet human needs. This study purposed to determine the level of preference and nutritional value of cookies with the addition of katuk leaves and moringa leaves as a snack for nursing mothers. This study used a factorial research design with 2 factors, namely 3 levels of katuk leaf flour (5 g, 10 g, 15 g) and 2 levels of moringa leaf flour (5 g, 10 g). The hedonic test data were processed using the Friedman test and further test with the Wilcoxon signed-rank test. Calculations used to test the effectiveness to determine the selected formula showed that the F4 treatment (5 g katuk leaf flour: 10 g moringa leaf flour) had the highest effectiveness value of 0.95. The results of the chemical test on the F4 treatment had a water content of 1.02%, carbohydrates 76.88%, protein 12.05%, fat 7.85%, and energy contributions of 423.50 kcal per 100 g, and 105.87 kcal per dose serving (30 g).

A imagem-experiência na intersecção de esferas da arte e da vida cotidiana
Authors: Gueller Viviane
Published: June 2022

Neste artigo, discuto a ocorrência da imagem-experiência, conceito operador de uma prática artística engendrado em minha tese de doutorado. Trata-se de uma ação originada em um gesto de colocar-se em disponibilidade perceptiva, um trabalho que nasce de situações de encontro despreparado, conformadas como brechas na vida cotidiana nas quais a imagem está carregada de experiência. A sua instauração na Galeria da Capela, em Lisboa, um espaço expositivo que mantém características históricas singulares relativas ao seu uso original, motivou a reflexão sobre uma intersecção entre dimensões da arte e da vida cotidiana, proporcionando o entendimento da presentificação como uma atualização da imagem-experiência.

Nenhuma galeria é um artista
Authors: Bucksdricker Jorge Alberto Silva
Published: June 2022

Poderia um artista ser uma galeria? A partir de um fragmento de um livro de artista de Antonio Dias e de considerações sobre o idealismo, esse artigo discorre sobre a publicação de periódicos no Brasil nas décadas de 1970 e 1980, procurando mostrar a sua importância para a circulação de proposições que não tinham espaço no circuito de museus e galerias e no contexto das grandes casas editoriais. Tomando essas publicações pelo viés institucional, o artigo procura mostrar como os artistas ampliaram o seu espectro de ação, interferindo nos processos de institucionalização e contribuindo para a renovação da crítica de arte.
