Background

Predicting which patients with American Joint Committee on Cancer (AJCC) T1–T2 melanomas will have a positive sentinel lymph node (SLN) is challenging. Melanoma Institute Australia (MIA) developed an internationally validated SLN metastatic risk calculator. This study evaluated the nomogram’s impact on T1–T2 melanoma patient management at MIA.

Methods

SLN biopsy (SLNB) rates were compared for the pre- and post-nomogram periods of 1 July 2018–30 June 2019 and 1 August 2020–31 July 2021, respectively.

Results

Overall, 850 patients were identified (pre-nomogram, 383; post-nomogram, 467). SLNB was performed in 29.0% of patients in the pre-nomogram group and 34.5% in the post-nomogram group (p = 0.091). The overall positivity rate was 16.2% in the pre-nomogram group and 14.9% in the post-nomogram group (p = 0.223). SLNB was performed less frequently in T1a melanoma patients in the pre-nomogram group (1.1%, n = 2/177) than in the post-nomogram group (8.6%, n = 17/198) [p ≤ 0.001]. This increase was particularly for melanomas with a risk score ≥ 5%, with an SLN positivity rate of 11.8% in the post-nomogram group (p = 0.004) compared with zero. For T1b melanomas with a risk score of > 10%, the SLNB rate was 40.0% (8/20) pre-nomogram and 75.0% (12/16) post-nomogram (p = 0.049).

Conclusions

In this specialized center, the SLN risk calculator appears to influence practice for melanomas previously considered low risk for metastasis, with increased use of SLNB for T1a and higher-risk T1b melanomas. Further evaluation is required across broader practice settings. Melanoma management guidelines could be updated to incorporate the availability of nomograms to better select patients for SLNB than previous criteria.

Published: May 2024

Considering the toxicity and environmental problems created using cyanide in industrial applications of gold extraction, intensive research has been developed during the decades for identifying new effective reagents able to replace cyanide in gold extraction operations. The high thermodynamic stability of gold complexes with certain compounds is the first prerequisite for the selection of a promising extractant. The stability of gold-thiosulphate complex, though considerably lower than that of cyanide, is the highest amongst other alternative ligands, and for this reason it has been thoroughly investigated with laboratory and pilot scale tests. Ca-thiosulphate salt was selected for evaluation in the framework of the present work, as a promising cyanide-free alternative for obtaining the recovery of gold from the pressure oxidation (POX) residue of gold bearing sulfide concentrates. Ca- thiosulfate leaching experiments were conducted, investigating parameters such as initial thiosulfate concentration, initial pH, temperature, and solid-liquid mixing ratio (S/L). Findings reveal promising gold recovery rates with potential optimization through parameter adjustments. The objective of this research is to offer valuable insights into the feasibility of employing thiosulfate as a gold recovery agent, advocating environmentally conscious practices in the metallurgical industry and addressing challenges linked to pressure oxidation residues

USING DIFFERENT MODIFICATIONS OF THE ALLIUM TEST TO EVALUATE RADIOTOXICITY OF BOTTOM SEDIMENTS OF THE YENISEI RIVER
Authors: Bolsunovsky Alexander Ya. , Trofimova Elena A.
Published: May 2024

Background. Bottom sediments (BS) of the Yenisei River contain xenobiotics of the chemical and radiation origins, which may adversely affect life functions of aquatic organisms. Previous assays of BS samples using the Allium test showed contradictory responses of the endpoints of onion bulbs (stimulation and inhibition) to the chemical and radionuclide composition of the BS. The Allium test with germinated seeds has not been used so far to test samples of the Yenisei BS, although previous studies showed sensitivity of this test object to exposure to low-dose gamma radiation.
Purpose. The purpose of the study was to assess the possibility of using two modifications of the Allium test (A. cepa bulbs and seeds) to evaluate toxicity of samples of the Yenisei River BS containing relatively high activity concentrations of artificial radionuclides.
Material and Methods. Toxicological laboratory experiments were conducted using three samples of the Yenisei BS containing high activity concentrations of the artificial radionuclide 137Cs; artificial BS prepared according to the standard protocol were used as the control. Activity concentrations of BS radionuclides were measured using a gamma-spectrometer coupled to a hyper-pure germanium detector (Canberra, U.S.). The test object was onion Allium cepa L. cv. Stuttgarter Riesen (bulbs and seeds). Root growth was chosen as the endpoint to determine BS toxicity. 
Results. Experiments with radioactive BS from the Yenisei River demonstrated significant stimulation of root growth in the modification with onion bulbs and inhibition of root growth in the modification with onion seeds. In previous research, stimulation of root growth was observed in onion bulbs exposed to Yenisei BS containing lower activity concentrations of 137Cs. For the first time, inhibition of root growth of onion seedlings was observed in assays with BS containing a wide range of 137Cs activity concentrations. 
Conclusion. Comparison of two modifications of the Allium test (bulbs and seeds) for assessing the toxicity of BS showed that only the growth of onion seedling roots used as an endpoint has sufficient sensitivity to the content of the artificial radionuclide 137Cs in BS and makes it possible to evaluate the biological effects of radioactivity.
Funding. The study was funded by State Assignment of the Ministry of Science and Higher Education of the Russian Federation (project No. 0287-2021-0019).

Authors: Solonkin Andrey V. , Guzenko Alexey Yu. , Guzenko Andrey V. , Seminchenko Elena V.
Published: May 2024

Background. Winter wheat is a key crop in most farms of the Volgograd region and the south of Russia. However, despite the high annual gross harvest of wheat grain in the region (4 million tons or more), its stabilization and increase in production are complicated by global and local climate changes, depletion of soil fertility, environmental pollution, narrowing of biodiversity of crops used in crop rotation, and other negative factors. The impact of external environmental factors on grain production is extremely difficult and requires a systematic approach in the study. Among the main trends in climate change, scientists of the Federal Research Center of Agroecology of the Russian Academy of Sciences note a steady increase in average air temperatures of the autumn-winter period, an increase in intra-seasonal variability.
Purpose. Improving the technology of winter wheat cultivation, studying the effect of mineral fertilizers and new biological products on the yield and quality characteristics of grain in the conditions of light chestnut soils of the Volgograd region
Materials and methods. The study of the effect of trace elements on the yield of winter wheat of the Kamyshanka 4 variety, as well as the analysis of qualitative indicators in the arid conditions of the Volgograd region based on the methodology of B. A. Dospekhov and gossorto-testing.
Results. According to the conducted studies, the greatest effect on the yield and quality of winter wheat was formed on the treatment with preparations of the Biostim series that affect the balance of nutrients during the growing season, protection from the effects of abiotic processes, restoration of crop productivity after stress.
Conclusion. When choosing plant nutrition with trace elements, it is necessary to proceed from soil and climatic conditions. As a result, in the arid conditions of the Volgograd region, results were obtained showing the important role of amino acids and trace elements in maintaining the balance of nutrients throughout the vegetation of plants.

Materials and methods. A review of the literature is presented and scientific studies on the content of trace elements in rice grain of various samples, including those with colored pericarp, as well as the genetics of this trait, are analyzed.]Review of the literature is presented and scientific studies on
Results. Insufficient consumption of microelements leads to metabolic disorders and the emergence of a range of diseases. Rice with black and red pericarp is one of the most promising sources of antioxidants and microelements; its content is 5-8 times higher than in the grain of usual rice varieties. The study of genetic mechanisms controlling the content of microelements is relevant in connection with their antioxidant and antimicrobial properties. It is established that the intra-species diversity observed at the phenotypic level is associated with both regulatory and structural genes. The study of the mechanism of genetic regulation of the accumulation of microelements in domestic rice varieties at the molecular level has not previously been conducted.
Conclusion. Data on the genetic regulation of the synthesis of substances that increase the nutritional value of grain (micro and macro elements, etc.), will allow to intensify the rice breeding for varieties development suitable for the functional food production.

Published: May 2024

The Achilles tendon is a strong tendon in the human body but is prone to rupture, especially during recreational activities. Misdiagnosis of ruptures can lead to chronic issues, affecting the quality of life. Surgical V-Y plasty is a technique used to treat chronic Achilles tendon ruptures by lengthening the tendon and restoring its continuity.
Two cases of Achilles tendon ruptures were presented, where V-Y plasty was performed along with immediate weight-bearing and rehabilitation. The patients showed significant improvement post-surgery, with no symptoms or restrictions on physical activity after about 6 months. The rehabilitation protocol included functional training, regenerative treatments, and follow-up visits to monitor progress.
Studies have shown that surgical treatment is more effective in preventing re-tears compared to conservative treatment for Achilles tendon ruptures. V-Y plasty has been proven to be an effective technique for treating chronic ruptures with large defects in tendon continuity. Immediate weight-bearing and rehabilitation post-surgery have shown positive outcomes in patient recovery.
Further research is needed to establish a standardized rehabilitation protocol for Achilles tendon ruptures. The unique management regimen used in the cases presented yielded successful results, emphasizing the importance of immediate rehabilitation post-surgery for improved patient outcomes. V-Y plasty with immediate weight-bearing and rehabilitation is a promising method for treating chronic Achilles tendon ruptures.

Basado en la teoría de los sistemas ecológicos, tres contextos sociales principales están asociados con la participación escolar. En ese sentido, el objetivo del presente trabajo fue conocer el impacto del apoyo social percibido sobre el rendimiento académico considerando el rol mediador del engagement académico y de la autoeficacia académica. Participaron 623 adolescentes peruanos de educación secundaria (51.364% mujeres) entre los 12 y 17 años (Medad = 14.255; DTedad = 1.454), quienes fueron evaluados con la Multidimensional Scale of Perceived Social Support, la Utrecht Work Engagement Scale – Student, la Escala de Autoeficacia Percibida Específica de Situaciones Académicas, y el rendimiento escolar se obtuvo directamente del registro de calificaciones de la institución. Se realizó un análisis de regresión estructural con el método de estimación de mínimos cuadrados con media y varianza ajustada y los parámetros se interpretaron bajo una perspectiva de magnitud del efecto. Se encontró que el apoyo social de los padres influye sobre la autoeficacia académica y el engagement académico; a su vez, la autoeficacia académica influye sobre el engagement académico y sobre el rendimiento escolar. Por otro lado, al considerar al rol mediador del engagement académico y de la autoeficacia académica, solo se encontró una influencia indirecta y significativa del apoyo social de los padres sobre el rendimiento escolar. En conclusión, la familia es un factor relevante para aumentar las creencias de autoeficacia y optimizar el rendimiento académico.

Authors: Guerrero-Bocanegra Borja
Published: May 2024

Tomando como referencia las elevadas tasas de abandono que afectan a la Educación a Distancia, en esta investigación se presenta una descripción comparada de las percepciones que tienen dos grupos de estudiantes de grado (nuevos y experimentados) en una universidad española pública a distancia, sobre las acciones que se pueden desplegar desde la institución para apoyarles en la consecución exitosa de sus estudios. El abordaje se ha llevado a cabo desde un enfoque cuali-cuantitativo de tipo descriptivo y con finalidad exploratoria. Los datos han sido recogidos mediante un cuestionario sobre una muestra no representativa de 1.166 estudiantes del curso 2021/2022. Los resultados indican que el perfil sociodemográfico más característico sigue siendo el de persona empleada por cuenta ajena que elige los estudios a distancia para compaginarlos con sus obligaciones laborales, así como una reducción de la edad promedio de los estudiantes que optarían por esta modalidad como primera opción. Del análisis inductivo de contenido emergieron 16 categorías temáticas que constituyen un compendio de acciones que, desde la percepción de los estudiantes, se deben priorizar para apoyarles en la consecución exitosa de sus estudios de grado, entre ellas: aumentar la supervisión y retroalimentación por parte de los docentes, mejorar los recursos didácticos, intensificar la coherencia y conexión entre los componentes curriculares, ofrecer más orientación académica, posibilitar hacer los exámenes de manera no presencial y mejorar las plataformas educativas.

Authors: Lucas-Oliva Inés , Moreno-Medina Irene
Published: May 2024

This study aims to explore the expectations and desires of students pursuing Education Sciences degrees regarding their studies. To meet this objective, and employing a mixed-methods approach with content analysis, the study examined the perspectives of a sample of 423 students enrolled in Primary Education, Early Childhood Education, and Pedagogy programs. Findings reveal a discrepancy between students' anticipated outcomes and the reality of their university education. While students expect primarily theoretical knowledge from their studies, they express a desire for more practical and professionally oriented training. In conclusion, these insights underscore the need for enhancements in teacher training programs to bridge the gap between academic learning and professional-world pedagogical demands. Addressing these gaps holds the potential to shape a more equitable and sustainable educational landscape for the future, fostering a student body that is more motivated and equipped with the required teaching competence. Further implications of this study are also discussed.
La pregunta niña: Disonancias entre el orden explicador y la afirmación vital
Authors: Visaguirre Leonardo javier , Quiroz María milena
Published: May 2024

Este trabajo surge de un diálogo interdisciplinario entre dos tesis doctorales, una de educación y otra de filosofía, que comparten un interés sobre formas emancipadoras y democráticas de pensar con otros y otras en la escuela pública latinoamericana. Desde una perspectiva crítica propia de la filosofía de la educación latinoamericana realizamos un análisis epistemológico sobre las distintas formas de habitar la pregunta dentro de una práctica filosófica con niños y niñas. Tomamos como objeto de estudio una experiencia específica de comunidad de indagación realizada en 2022 en el sur de Mendoza, Argentina. Entramamos herramientas teóricas de Walter Kohan, Paulo Freire y Jacques Rancière con la intención de visibilizar diversas formas de habitar la producción de saberes dentro de dicha comunidad. Proponemos dos nudos problemáticos: por un lado, el orden explicador/embrutecedor a partir de Rancière y, por el otro,la pregunta como afirmación vital a partir de Kohan y Freire. Trabajamos una serie de disonancias en torno a la circulación y a la potencia de la pregunta en la escuela y la educación pública. Finalmente proponemos una síntesis de estas problemáticas en la postulación de una “pregunta niña” como potencia epistémica emancipadora que supone una intimidad con los otros y otras, con las cosas y el mundo abierta desde una igualdad política e intelectual radical.

Enquanto que, sobre os saberes e a identidade docente, conclui-se que não são imutáveis, fixos e tampouco aplicáveis de uma realidade a outra, sendo construídos e reconstruídos ao longo do exercício da profissão docente, conforme o contexto espaço-temporal em que se desenvolve a docência.
PUNIÇÃO E JUSTIÇA INFANTOJUVENIL
Authors: Da Silva Jenifer Stefani , Duarte dos Reis Farias Priscila
Published: May 2024

O presente artigo propõe discutir as aproximações entre o encarceramento e o sistema de justiça infantojuvenil, mediante uma análise a partir de como o Estado e a sociedade têm lidado com a chamada “guerra às drogas” quando esta atinge populações ainda na adolescência, trazendo o resultado de alguns trabalhos de pesquisa das autoras. Para isso, inicialmente traçamos um histórico sobre como a infância pobre, preta e desvalida foi desde sempre punida com amparo legal e institucional, discorrendo inclusive sobre o histórico de tais instituições destinadas a crianças e jovens pobres e “infratores” até os dias atuais. Para tal, esboçamos um breve histórico dos marcos legais que embasaram e deram origem a proteção e institucionalização de crianças e de adolescentes no Brasil, trabalhando também o histórico das instituições legalmente investidas do direito de colocar em prática as medidas de privação total ou parcial de liberdade e uma análise acerca da relação do sistema infantojuvenil com a guerra às drogas no estado do Rio de Janeiro. Como metodologia utilizamos a análise documental e bibliográfica. Autores como Wacquant (1999), Melossi (2004), Marx (2015) etc. fundamentam este trabalho que, apesar de acadêmico, se apresenta também como um posicionamento político necessário para os dias atuais.
MEMES ANTIFEMINISTAS E CONSERVADORISMO EM REDE: UMA ANÁLISE DAS LEITURAS E ENQUADRAMENTOS DOS FEMININOS DESVIANTES
Authors: Domingues Quésia Alves de Souza Sanches , Pesce Lucila
Published: May 2024

O presente artigo caracteriza-se, metodologicamente, pela abordagem qualitativa, de natureza exploratória, consubstanciada pela análise de conteúdo. O objetivo geral consiste em examinar o conteúdo de memes antifeministas coletados no portal aberto do Facebook “Antifeminista" para compreender em que medida os sentidos socialmente depreendidos das representações do feminino feitas pelos ideais ligados ao conservadorismo hodierno apresentam potencial para capitanear possíveis propostas sociais de formação leitora crítica, no contexto da cultura digital, pensando em descontruir estereótipos e leituras restritivas das existências femininas. O marco teórico ergue-se em meio aos seguintes campos conceituais: ciberespaço e cidadania (LÉVY, 2000); multiletramentos (KNOBEL  e LANKSHEAR, 2007; ROJO e MOURA, 2012); formação leitora crítica (DEWEY, 1959; FREIRE, 1989); memes antifeministas (ANJOS, 2017; SABBATINI, 2020). O método de análise dos dados pautou-se no enquadramento das peças coletadas em uma matriz taxonômica adaptada da proposta de Chagas et al. (2017), construída para analisar memes políticos.  Os achados da pesquisa revelam que o enunciador lança mão de uma gama diversa de estratégias linguísticas e discursivas, para persuadir e alimentar o repertório do leitor não crítico, com o objetivo de descredibilizar o movimento feminista e perpetuar relações de dominação de gênero. Assim, os resultados sugerem também que os memes analisados apresentam-se como importantes recursos para nortear propostas e práticas educativas de leitura, que constituam experiências de expansão da consciência e problematizem as enunciações opressivas que transitam nos espaços virtuais.
Achievement of student paramedic competency in out-of-ambulance settings
Authors: Salisbury Kurstin , Hillier Dendra , Bons Erin , Cadeau Terri , Brooker Vanessa
Published: May 2024

Competency in key areas is required for job readiness for paramedics, and is monitored by preceptors through in-ambulance placements. Without preceptors, learners are unable to move forward with their training and diploma completion. To address this, an alternative model in community settings to provide students with effective learning opportunities could be explored. This study aimed to evaluate the efficacy of an out-of-ambulance placement model on competency achievement for students in a 2-year primary care paramedic diploma programme at a Canadian college. One cohort of second-year students selfselected a hybrid model of placement, where 6 weeks of training were completed in ambulance and 6 weeks out of ambulance. Competencies were tracked and approved by preceptors, who were certified paramedics and other health professionals. Results were recorded using paramedic competency tracking software and analysed. Compared to traditional placement, the hybrid placement model resulted in a similar average number of competencies being achieved and provided unique opportunities for competency achievement across groups. A hybrid model of placement was shown to have comparable value to a traditional model in competency achievement.

The synthesized samples were characterized by various techniques. XRD results revealed that Zn2+ and Ag+ were incorporated into a hexagonal framework of HA. FT-IR analysis showed that the main functional groups were hydroxyl and phosphate groups. SEM images showed a rough surface morphology, which consists of very small spherical particles. TEM images revealed the homogeneous distribution of Zn2+ and Ag+ in the synthesized samples. Antibacterial activity of the Zn-Ag doped GRHA against five strains of bacteria including S. aureus, B. cereus, B. subtilis, P. aeruginosa and E. coli was investigated. Zn0.75Ag0.25 doped GRHA showed excellent antibacterial activity against all strains except P. aeruginosa.

Due to their superior thermal, electrical, and mechanical properties, brass and Cu-Zn alloys are widely used in a broad range of applications. In applications requiring greater durability, corrosion resistance, and wear resistance, however, the ZnO/Cu composite is preferable. Typically, ZnO/Cu composites are manufactured through powder metallurgy. In this article, brass strips are thermally oxidized in an oxygen atmosphere to produce ZnO/Cu composite strips. The optimal temperature and oxygen pressure are 600–650 °C and less than one atmosphere, respectively. The homogeneous distribution of nanoscale ZnO clusters in the Cu matrix can be attributed to the diffusion of both Zn and O in the matrix. In addition, the composite is substantially harder than brass, increasing from 70–90 HV to 200–240 HV. Therefore, thermal oxidation has been shown to be a simple and cost-effective process for producing ZnO/Cu composites with high hardness.

Objective:

To correlate the findings of conventional radiography and magnetic resonance imaging in acute and chronic cases of seronegative spondylo-arthropathies and also to correlate the outcomes of different sequences of MRI especially STIR and Gadolinium contrast-enhanced TIWI with emphasis on sacroiliac joints.

Methods:

A total of 100 cases were included in this prospective case study who was met the ASAS criteria. Firstly, radiographic findings in all the cases were evaluated and were graded (0-4) according to modified New York Criteria 1984. Secondarily MRI of the pelvis was done including bilateral sacroiliac and hip joints. An axial oblique and semicoronal section were obtained along the long axis of sacral bone with TIWI, STIR, and post-gadolinium T1W MRI findings like; periarticular bone marrow edema, capsulitis, synovitis, enthesitis, erosion, and ankylosis were noted and analysed. Biochemical investigation ESR, Rheumatoid factor, C-reactive protein, and HLA-B27 were also done.

Results:

Among MRI findings suggestive of acute sacroiliitis, the most common was BME (41%) followed by synovial enhancement (14%), enthesitis (8%) and capsulitis (6%) respectively. Post-gadolinium TIWI showed significant synovial enhancement in the younger (<19 years) age group.

Conclusions:

HLA B-27 had a strong association with the SpA. However, further studies with a larger sample size are needed. ESR and CRP were found to be good laboratory marker for SpA activity. STIR and T1WI MR sequences were sufficient for making the diagnosis of either active or chronic sacroilitis. Synovial enhancement on the post-contrast T1W sequence was statistically significant (p <0.001) in pediatric patients than adults.

Mangrove ecosystem is an ecosystem that supports people's lives and the biota that live in it. Globally, mangrove ecosystems are recognized as productive ecosystems in coastal areas. Mangrove wetlands have an important function of protecting coastal ecology, buffering salinity, breeding grounds for organisms and transporting nutrients. Research on the assessment of the quality of mangrove ecosystems in Syiah Kuala District, Banda Aceh City was carried out with the aim of studying the presence of mangrove species, plankton species, hydrological factors of mangrove ecosystems and analyzing the quality of mangrove ecosystems as breeding grounds for organisms based on hydrological factor values. The method used in this study was the line transect method and the research technique was carried out by means of purposive sampling. Data analysis was calculated using the Shanon-Wiener Species Diversity Index (Ĥ) and PCA (Principal Component Analysis) analysis. Identification results showed a low mangrove species diversity index with a value of Ĥ = 1.924, a plankton species diversity index of Ĥ = 2.614 belonging to moderate community stability, a hydrological index covering temperatures ranging from 28.2 to 29.8 ⁰ C, pH 7.1 -7.4, DO 2.9-4.1 mg/L, salinity 27-20.9 ⁰/₀₀, brightness 30-68.5 Cd, depth 88.5-105 cm. Water quality parameters are in good condition. PCA analysis showed a correlation between the distribution of mangrove species and parameters of salinity, pH, DO, temperature, depth and brightness.Keywords:MangrovesBreeding SiteHydrologyPlanktonCoastal Area

Published: May 2024

Organic matter entering through the inlet and activities in the Koto Panjang Reservoir body is feared to be the main source of nutrient contribution in the form of nitrogen (N) and phosphate (P) for reservoir waters. Nutrients N and P are utilised by phytoplankton in the photosynthesis process. If this condition continues, it is feared that it will affect water quality (blooming algae) which has an impact on aquatic biota. This study aims to determine the type and abundance of phytoplankton along with the distribution of chlorophyll a in reservoir waters. This study used descriptive, qualitative and quantitative methods and analysed the distribution of chlorophyll a using surfer software.  Based on the results of the study, it is known that water quality is relatively good with temperatures ranging from 26-310C, brightness ranging from 0.69-1.96 m, dissolved oxygen (DO) is 5.60-6.80 mg/L and turbidity is 1-6 NTU. The results showed that phytoplankton composition was composed of 5 classes consisting of Euglenophyceae (1 species), Cyanophyceae (3 species), Conjugatophyceae or Zygnematophyceae (4 species), Chlorophyceae (4 species) and Bacillariophyceae (10 species). The dominating class in the reservoir zonation is different. In the riverine zone the Bacillariophyceae class dominates by 60.06%, in the transition zone the Cyanophyceae class by 91.60% and in the lacustrine zone the dominating class is Conjugatophyceae or Zygnematophyceae by 78.69%. Phytoplankton abundance ranged from 166.5-2,193 sell/m3.  The highest abundance was located in the lacustrine zone and the lowest abundance in the riverine zone. The distribution of chlorophyll a in Koto Panjang Reservoir is varied, the highest distribution is located in the transition zone to the lacustrine zone.

Environmental mitigation measures are being undertaken as a proactive approach to prevent the adverse consequences associated with Harmful Algal Blooms (HABs). Presently, there is a lack of comprehensive information regarding the occurrence of HABs in the waters surrounding Bintan Island, and routine monitoring to assess the potential for eutrophication is absent.  This research should begin by gathering information about potential sources that contribute to the emergence of HABs, the specific types of algae with the capacity to trigger HABs The primary objective of this study is to identify the harmful algae species present in the coastal waters of Bintan Island. The research was conducted in August 2023, with the sampling process taking place at four specific locations within the coastal waters of Bintan Island. These sampling stations were selected deliberately to capture the varying activities predominant in each respective area. The microalgae found consisted of four groups, namely Bacillariophyta, Cyanophyta, Dinophyta, and Chlorophyta. Bacillariophyta is a group of microalgae with the highest abundance proportion at all observation stations. Harmfull Algae found in the coastal waters of Bintan Island generally come from the Dinophyta group of the types Ceratium sp., Peridinium sp., Prorocentrum sp., and Dinophysis sp. Harmful microalgae from the Dinophyta group were found at all research stations, with the highest proportion of abundance at Station 2 (6%) and the lowest at Station 3 (1%). The difference in these findings is thought to be due to the dynamics of the hydrosanographic parameters of the waters, especially nutrient concentrations.Keywords:BintanCeratiumDinophytaHarmfulMicroalgae

Published: May 2024

Ectoparasite infections are a common problem in small-scale aquaculture, exerting a substantial influence on fishery production. In the context of Indonesia, the two prevalent fishery commodities are whiteleg shrimp Litopenaeus vannameii and mud crab Scylla serrata. These species are extensively cultured within Aceh province, using traditional and semi-intensive aquaculture ponds and there are no reports on ectoparasites in these two species of crustaceans. Therefore, this study aimed to analyze the intensity and prevalence of ectoparasites in mud crab and whiteleg shrimp from Aceh between August to December 2022. Mud crab samples were collected from three locations, namely Langsa City, East Aceh, and North Aceh districts, while whiteleg shrimp samples were sampled from coastal ponds in Banda Aceh, Aceh Besar, and Aceh Jaya districts. The samples were collected over five months, and a total of 300 for each species were examined microscopically by scraping the swimming legs body, and gills. Furthermore, macroscopic-sized and microscopic-sized ectoparasites were observed using stereo and binocular microscopes, respectively. The results showed that five species of ectoparasites were recorded during the study, namely Octolasmis sp., Vorticella sp., Epistylis sp., Oodinium sp., and Zoothamnium sp. Mud crab exhibited infestations of Octolasmis sp., Vorticella sp., Epistylis sp., and Oodinium sp., while whiteleg shrimp were infested by Vorticella sp., Epistylis sp., and Oodinium sp. In this study, the highest intensity for crab and shrimp was recorded in Octolasmis sp. and Epistylis sp., in November and September, respectively. The gills showed higher intensity compared to other infested organs and based on sample origin, crab and shrimp from Langsa and Banda Aceh Cities had higher results compared to other locations. The prevalence of ectoparasites exhibited a high value, reaching 100%, showing that crustacean samples were infested by ectoparasites. Therefore, the intensity of ectoparasite was varied according to sample of origin, time of sampling and infested organs. The samples of both crab and whiteleg shrimp from all locations consistently exhibited ectoparasite infestations throughout the entire study period.Keywords:Octolasmis sp.Vorticella sp.Epistylis sp.Oodinium sp.Zoothamnium sp.
