Panorama del teatro aplicado a la prevención de la violencia y el delito en la ciudad de México
Authors: Meza Cosme Susana
Published: January 2025

En la segunda década de los años 2000, en México hubo un cambio de paradigma en la política de seguridad pública: se transitó del punitivismo hacia la prevención social de la violencia y el delito en concordancia con lineamientos internacionales en la materia. Por ello, se llevaron a cabo proyectos de prevención que utilizaban las artes, y, entre ellas, el teatro. ¿Cómo se instrumentaron dichos proyectos? ¿En qué medida puede ser el teatro una herramienta para la prevención de la violencia y el delito? ¿Cuáles son las condiciones para una mejor práctica del teatro aplicado a este tipo de prevención? Para responder estas preguntas, se partió de la investigación documental y la observación participante para analizar proyectos teatrales llevados a cabo de 2010 a 2019 con policías, personas privadas de la libertad y en comunidades con altos índices delictivos en la Ciudad de México. La investigación arrojó que los cambios logrados en su mayoría son tácticos y no estratégicos, y que estas son prácticas teatrales atravesadas por numerosas tensiones éticas y estéticas.

Reactive oxygen metabolites and antioxidants, as well as the redox-sensitive signaling Nrf2-dependent pathway, play a dual role in the formation, growth and progression of malignant neoplasms. The aim of the study was to investigate the ability of the original synthetic monophenolic antioxidant of combined action to influence tumor growth in vivo and the side effects of cytostatic use. Material and methods. Lewis lung carcinoma (LLC) was used as an experimental model of malignant growth. The study was performed on 120 female C57Bl/6 mice, which were divided into 12 groups; the animals were weighed weekly. Mice of the corresponding groups received intragastrically a solution of sodium 3-(3′-tert-butyl-4′-hydroxyphenyl)propylthiosulfonate (TS-13) (100 mg/kg body weight), a suspension of tert-butylhydroquinone (tBHQ) or a solvent (0.9% NaCl solution) throughout the experiment. 28 days after the start of TS-13 and tBHQ administration, mice were implanted intramuscularly with a suspension of LLC cells at a dose of 2×105 cells/mouse; on the 7th and 14th days of tumor development, a solution of doxorubicin was administered intraperitoneally twice at a cumulative dose of 8 mg/kg body weight (4/5 LD10). On the 35th day of tumor growth, the animals were removed from the experiment, the tumor was extracted, weighed and its linear dimensions were determined; the tumor mass coefficient and volume were calculated, respectively. The spleen mass coefficient was also estimated. Results and discussion. On the 7th and 14th days of tumor growth, the body weight of animals receiving TS-13 and tBHQ was statistically significantly greater than that of other tumor carriers. Administration of TS-13 to mice inhibited tumor growth as effectively as doxorubicin, and more significantly when used in combination; tBHQ did not exert an independent inhibitory effect, and did not enhance its effect in combination with the cytostatic. Doxorubicin significantly reduced the spleen mass coefficient, while TS-13 and tBHQ statistically significantly reduced the effect of the cytostatic. Monotherapy with doxorubicin was accompanied by hair loss on the dorsal surface (8 animals out of 10), while no alopecia was observed with the combined administration of the cytostatic with TS-13 and tBHQ. Conclusions. Monophenol TS-13, a direct antioxidant and inducer of the Keap1/Nrf2/ARE system, is comparable to doxorubicin in terms of its antitumor effect. The use of TS-13 allows to significantly reduce the negative manifestations associated with malignant growth and the side effects of chemotherapy, such as cachexia, splenotoxity, and alopecia.

Authors: Romancini Sônia Regina , Fonseca Swelington de Lima , Silva João Márcio Palheta da
Published: January 2025

O presente estudo avalia os processos de ordenamento territorial em andamento na Amazônia Legal após a década de 1970, com foco na área de abrangência da rodovia Cuiabá-Santarém (BR-163), nos estados de Mato Grosso e Pará, considerando os efeitos modernizantes nos circuitos produtivos e os impactos socioeconômicos. Ao longo das últimas cinco décadas, os fluxos e as trocas entre esses dois estados vêm se intensificando por meio da integração viária e de projetos de poder engendrados pelo Estado e pelo capital privado dos grandes conglomerados do agronegócio e da mineração. Tais agentes controlam, de forma hegemônica, o campo, as cidades, as redes, moldando a fronteira dos territórios do Mato Grosso e do Pará em função da reprodução ampliada de capital.
Implicações da expansão capitalista na fronteira no contexto “Pós-operação Amazônia”: desenvolvimento para quem?
Authors: Carvalho André Cutrim
Published: January 2025

O presente artigo tem como objetivo discutir as principais implicações socioeconômicas da expansão do capital na fronteira da Amazônia na década de 1960, sobretudo no Estado do Pará, após a “Operação Amazônia”, bem como responder ao seguinte questionamento: houve, de fato, algum tipo de desenvolvimento? Para isso, urge adotar como procedimento metodológico uma abordagem do tipo qualitativa-exploratória. Ao analisar o desempenho da economia amazônica e, particularmente, da economia paraense, fica evidente que com a política de desenvolvimento industrial e com a própria pecuariazação da região, se teve êxito do ponto de vista do crescimento econômico, mas alcançaram-se resultados pouco satisfatórios do ponto de vista social. Este foi o caso da estratégia desenvolvimentista aplicada pelos militares através da “Operação Amazônia” que, por um lado, conseguiu realizar a “abertura” da Amazônia, ampliando sua base infraestrutural, descobrindo suas potencialidades e atraindo grandes empreendimentos voltados para a exportação econômica; por outro lado, os seus instrumentos de políticas públicas evidenciaram-se ser de pouco alcance, no sentido de não terem conseguido dotar a região de um processo autossustentado de desenvolvimento regional, em particular para a fronteira paraense.

O objetivo deste trabalho é analisar as mudanças da cobertura da terra, na Área de Proteção Ambiental da Baixada Maranhense, inserida em uma Fronteira Agropecuária da Amazônia Brasileira, considerando os anos de 2000, 2010 e 2020. A metodologia exploratória foi utilizada nesta pesquisa, apoiada na modelagem dinâmica espacial, onde se realizou etapas de organização de dados, cálculo de taxas de transição, geração de pesos de evidência de variáveis explicativas, calibração do modelo e validação. Os principais resultados mostram que: a) houve redução nas taxas de transição entre os anos avaliados; b) as variáveis escolhidas permitiram alcançar um índice de similaridade de até 73%; c) a principal classe de destino das transições foi a Pastagem Manejada. Conclui-se que as variáveis escolhidas nesta pesquisa permitiram a construção de um modelo condizente com as transformações nessa fronteira amazônica, seja através da lógica de transformação histórica, seja através dos programas de monitoramento da Amazônia. Este trabalho subsidia a elaboração de cenários alternativos para a área de estudo, tendo em vista a confiabilidade alcançada pelo modelo.
Supposition: no Problem for Bilateralism
Authors: Simonelli Ryan
Published: January 2025

In a recent paper, Nils Kürbis argues that bilateral natural deduction systems in which assertions and denials figure as hypothetical assumptions are unintelligible. In this paper, I respond to this claim on two counts. First, I argue that, if we think of bilateralism as a tool for articulating discursive norms, then supposition of assertions and denials in the context of bilateral natural deduction systems is perfectly intelligible. Second, I show that, by transposing such systems into sequent notation, one can make perfect sense of them without talking about supposition at all, just talking in terms of relations of committive consequence. I conclude by providing some motivation for adopting this normative interpretation of bilateralism on which this response to Kürbis’s argument is based.

Jednym z najważniejszych filarów geopolitycznych działań Iranu w regionie i poza nim jest koncepcja Osi Oporu. Stwarza ona możliwości rozszerzania wpływów i potęgi Teheranu oraz równoważenia jego wrogów jak najdalej od jego granic. Ta konfrontacyjna polityka w regionie nie jest jednak prowadzona w politycznej próżni. Ma ona wpływ nie tylko na podmioty regionalne, ale także na wiodące światowe mocarstwa. Rosja jest jednym z nich. Głównym celem niniejszego artykułu jest analiza podejścia Rosji do polityki irańskiego Frontu Oporu. Aby to osiągnąć, artykuł poruszy kilka kluczowych elementów, w tym irańską koncepcję Frontu Oporu, historyczną perspektywę podejścia Rosji do Iranu (po zimnej wojnie) oraz ograniczenia wsparcia Kremla dla polityki Teheranu.

Published: January 2025

Background: The integration of drip irrigation and nitrogen fertilization presents a synergistic approach to optimize okra production. Drip irrigation not only ensures efficient water use but also facilitates the precise application of fertilizers, thereby enhancing nutrient availability and nutrient uptake. This targeted approach helps in minimizing nutrient losses through leaching and volatilization, issues commonly associated with conventional fertilization application. Methods: A field experiment was conducted at Water Technology Centre, College of Agriculture, PJTSAU, Rajendranagar, Hyderabad during summer, 2021 on “Optimization of irrigation and nitrogen levels under drip fertigation in okra (Abelmoschus esculentus L). The experiment was laid out in a split-plot with three replications Bhendi crop (Radhika hybrid) was sown at a spacing of 40 cm x 45 cm. The treatments comprised of three irrigation levels scheduled through drip scheduledat 0.75 Epan, 1.0 Epan and 1.25 Epanin main-plots and four nitrogen levels viz., 75% RDN (112.5 kg N ha-1), 100% RDN (150 kg N ha-1), 125% RDN (187.5 kg N ha-1) and 150% RDN (225 kg N ha-1) in sub-plots. Experimental soil was sandy clay in texture, alkaline in reaction, medium in organic carbon content, low in available nitrogen, high in available phosphorous and available potassium, respectively. Result: The results indicated that, the highest leaf area index, root biomass, pod chlorophyll content and crude fibre content were highest under drip irrigation scheduled at 1.0 Epan treatment. Among the nitrogen levels the highest leaf area index, root biomass, pod chlorophyll content and crude fibre content were recorded with 100% RDN (N2) treat. Among the interaction of treatment combinations, the crop irrigation scheduled at 1.0 Epan in conjunction with 100% RDN (I2N2) recorded maximum leaf area index, root biomass, pod chlorophyll content and crude fibre content.

Published: January 2025

Background: The use of edible coatings has achieved increasing attention as an eco-friendly and health-conscious method for enhancing the shelf life and quality of food products. Biosurfactants are amphiphilic compounds produced by microorganisms. These compounds possess both hydrophilic and hydrophobic moieties, allowing them to interact with both polar and nonpolar substances. Methods: This study investigated the antifungal efficacy of rhamnolipid, sophorolipid and surfactin coatings with synergistic potential Aloe vera gel against Botrydiplodia theobromae. In present study, petri plates were supplemented with different biosurfactants at varying concentrations with Aloe vera gel used to control the B. theobromae. Result: The solutions of rhamnolipid, sophorolipid and surfactin (50 mg/L), Aloe vera gel (25%) and synergistic effect of rhamnolipid, sophorolipid and surfactin (10 mg/L) with aloe vera gel (25%) were evaluated for their biocontrol activity on B. theobromae and found that rhamnolipid alone showed comparatively low antifungal activity while rhamnolipid with aloe vera showed high antifungal activity with lower rhamnolipid concentration. The results indicated that a combination of rhamnolipid and aloe vera gel exhibited the highest antifungal activity against B. theobromae without significant phytotoxicity or cytotoxicity. It was observed that the biosurfactants cause rupture of mycelia as its evident from the microscopy. These findings suggest that rhamnolipid-based edible coatings could serve as a promising alternative to chemical fungicides for the management of post-harvest losses.
Entre traditionalisme et modernité : une lecture de L’Été enchanté de Paule Daveluy
Authors:   Société d’Etudes Franco-coréennes, SHIN Junga
Published: January 2025

Publié en 1958, L’Été enchanté de Paule Daveluy marque le début de la modernisation du roman québécois pour adolescentes, s’éloignant des tendances conservatrices et moralisatrices de l’époque.
Ce roman autobiographique explore la vie intérieure d’une jeune fille de 16 ans, décrivant son évolution psychologique et ses émotions avec soin. Bien que des éléments de modernité émergent, le récit reste ancré dans des valeurs traditionalistes, comme l’importance de la famille et de la religion.
Sur le plan formel, le roman innove en adoptant un point de vue à la première personne, un procédé peu courant à l’époque. Il recourt également au passé pour donner la voix à la protagoniste adulte qui se remémore ses seize ans. Ainsi, tout en racontant l’action, l’héroïne commente ses émotions et ses réactions en tant que narratrice.
En somme, L’Été enchanté oscille entre traditionalisme et modernité, et demeure une lecture précieuse pour les adolescentes, leur offrant une leçon de maturité, loin des idéologies nationalistes et des rô̂les traditionnels des femmes.
Comment enseigner l’article en français aux apprenants coréens de niveau débutant?
Authors:   Société d’Etudes Franco-coréennes, LEE Kyeong-Soo
Published: January 2025

L’article en français est l’un des items grammaticaux les plus difficiles à maîtriser pour les apprenants coréens. Cela s’explique principalement par l’absence de système d’articles dans la langue coréenne et par le fait que le français, contrairement à l’anglais, relativement familier aux apprenants coréens, possède trois types d’articles : l’article indéfini, l’article défini et l’article partitif. Ainsi, la question de l’enseignement des articles français aux apprenants coréens a toujours occupé une place centrale dans la didactique du FLE. En effet, de nombreuses études sur l’enseignement efficace des articles ont été menées, mais la plupart se sont concentrées sur l’analyse des erreurs commises par les apprenants coréens à partir de questionnaires. Cette étude s’inscrit dans la lignée de ces recherches, mais elle vise à proposer un modèle d’enseignement/apprentissage des articles en français spécifiquement adapté au niveau débutant.
Intersectionality of LGBTQ+ Disabled Individuals and Their Work Experiences: A Review of the Literature
Authors: Huibregtse Kathy , Granger Teresa Ann
Published: January 2025

Having multiple-minority status, individuals who have a disability and identify as lesbian, gay, bisexual, transgender, and queer (LGBTQ+) are at the intersection of multiple stigmatized identities (Kempapidis et al., 2023). Individuals with disabilities and who identify as LGBTQ+ are not in abundance but do exist. The workplace environment matters significantly for LGBTQ+ individuals with disabilities (Holman et al., 2018). Literature suggests that the combination of the social stigma strain of being, having a disability, and having other barriers to work can be a lot to manage. Furthermore, in addition to all those components experiencing the daily stress of living with discrimination, hate, and stigma as well as encountering social situations can be all too much. The experiences of the LGBTQ+ or LGBTQIA population including gender-nonconforming, intersex, and asexual remain poorly understood, underexamined, and underrepresented in the extant literature. LGBTQ+ experiences and behaviors of these workers are typically misunderstood and underrepresented in the literature. The purpose of this literature review is to synthesize the extant literature on the employment experiences of LGBTQ+ individuals with disabilities and to examine the importance of recognizing intersectionality in the workplace.

Authors: Pinheiro Lidiane Santos de Lima
Published: January 2025

O artigo resulta de uma pesquisa qualitativa sobre os discursos da Petrobras na última década. Por meio de revisão de literatura e estudo de caso relacionado à maior estatal do país, objetiva analisar o que há de mítico no ethos discursivo da marca, sobretudo, depois da operação Lava Jato, quando passa a ser projetada a venda de ativos da companhia. Com base nas reflexões de Roland Barthes e em diálogo com os estudos do discurso, o artigo demonstra que a Petrobras mítica, enunciada desde a sua fundação como “símbolo de Brasil”, é atualizada na proposta de transformação e desinvestimento da estatal, mas não sem disputas no processo de circulação de sentidos.

Published: January 2025

Growing apprehension among internet users regarding cyber-security threats, particularly Distributed Reflective Denial of Service (DRDoS) attacks, underscores a pressing issue. Despite considerable research endeavors, the efficacy of detecting DRDoS attacks remains unsatisfactory. This deficiency calls for the development of pioneering solutions to enhance detection capabilities and fortify cyber defenses against this sophisticated subtype of Distributed Denial of Service (DDoS) attacks. This study addresses this challenge by utilizing four distinct machine learning algorithms: SVM, DT, RF, and LR, supplemented by PCA. Leveraging the CIC Bell DNS 2021 dataset, our experiments produce compelling results. Specifically, both DT and RF algorithms exhibit exceptional performance with 100% accuracy and perfect F1 scores. This remarkable performance holds true with or without PCA-based feature reduction, except for dataset 4. Consequently, our research highlights the potential of machine learning in detecting and mitigating DRDoS attacks, offering valuable insights for bolstering cybersecurity measures against evolving threats.

[Conclusion] There is a need to actively reflect the characteristics of learners in the microlearning content design process, and there is a need to continuously upgrade the learning support system for various usability and accessibility of microlearning content.
O que significa “esquematizar sem conceitos”? Imaginação, esquematismo cognitivo e esquematismo estético na filosofia de Kant
Authors: Oliveira Eliakim Ferreira
Published: January 2025

Tencionamos apresentar uma explicação do que seja o esquematismo sem conceitos, a fim de solucionar algumas supostas contradições com relação ao que Kant apresenta no capítulo Do esquematismo dos conceitos puros do entendimento, na Crítica da Razão Pura. O problema sobre o qual discorremos pode ser assim formulado: o que devemos entender por esquematismo sem conceitos e em que deve consistir o esquematismo enquanto uma atividade geral da imaginação? Vamos defender a tese de que o esquematismo sem conceitos consiste em um procedimento de sensificação da unidade do juízo de gosto.
Espectador imparcial e o senso comum
Authors: Santos Cleiton Marcolino Isidoro dos
Published: January 2025

Neste artigo, busco apresentar as conexões entre a noção de espectador imparcial em Smith e a concepção de senso comum em Kant, sob a interpretação de uma filosofia política kantiana desenvolvida por Arendt. Para isso, demonstro os meios pelos quais Arendt propõe uma nova concepção de filosofia política, fundamentada nos juízos estéticos reflexionantes da Crítica da faculdade de julgar. Em seguida, exponho os principais elementos que caracterizam a figura do espectador imparcial smithiano. Por fim, indico que, com base na plataforma epistemológica proposta por Arendt, a noção de senso comum e a figura do espectador imparcial compartilham elementos semelhantes de atuação política, tanto em nível teórico quanto prático.
O liberalismo e a beneficência em Kant segundo Aguinaldo Pavão
Authors: Pereira Junior Antonio Alves
Published: January 2025

O presente artigo pretende expor a interpretação do liberalismo e da beneficência em Kant, a partir de Pavão (2023), que defende Kant como partidário do liberalismo clássico, dentre outros motivos, em especial aqui, por aquele que diz que a beneficência é um dever da virtude e não uma exigência feita pelo direito (e, por conseguinte, também não sendo uma exigência do Estado). Tal concepção será tencionada, comparada e criticada tendo em vista a concepção de cidadão ativo (activer Staatsbürger), de Kant. Sendo o cidadão ativo aquele que exerce trabalho autônomo e se sustenta de modo independente na sociedade, a questão a ser respondida é a seguinte: é possível, em Kant, derivar um impacto jurídico menor em coagir os ricos a praticar ações benevolentes do que aplicar um mesmo tipo de coerção nos pobres ou permaneceria valendo a tese do liberalismo clássico de Kant proposta por Pavão?
Kant versus Forster
Authors: Alves Luhan Galvão
Published: January 2025

Seguindo uma linha de discussão aberta por Patricia Kauark-Leite em seu texto Sobre a pluralidade de naturezas: Kant em diálogo com Forster, neste artigo, objetivamos aprofundar um dos pontos da tensa discussão entre Kant (filosofia) e Forster (ciência) no século XVIII, a saber: o direito de um investigador da natureza fazer uso de princípios teleológicos, quando lhe faltam os recursos pela via teórica para avançar o conhecimento. Com esse propósito, buscamos dar ênfase aos termos colocados por Kant no texto Sobre o Uso de Princípios Teleológicos na Filosofia (1788), por entender que a sua parte da discussão traz para o debate uma questão de direito (presente nas discussões da primeira e da terceira Crítica), fundamental a filósofos e cientistas quando empenhados em um diálogo aberto sobre uma forma de conhecimento.

Published: January 2025

Electrochemical biomass upgrading is a promising substitute for oxygen evolution reaction (OER) to generate valuable chemicals in conjunction with hydrogen generation. Pursuing highly efficient and durable electrocatalysts for significant concentration levels (≥ 50 mM) of biomass electrooxidation remains an enduring challenge. Herein, we introduce a robust Cu-supported CoFe Prussian blue analogue (CoFe PBA/CF) electrocatalyst, adept at facilitating high-concentration (50 mM) 5-hydroxymethylfurfural (HMF) oxidation into 2,5-furandicarboxylic acid (FDCA), achieving an exceptional HMF conversion (100%) with a notable FDCA yield of 98.4%. The influence of copper substrate and adsorption energy are therefore discussed. Impressively, the CoFe PBA/CF electrode sustains considerable durability in a continuous-flow electrochemical reactor designed for consecutive FDCA production, showcasing FDCA yields of 100/94% at flow rates of 0.4/0.8 mL·min-1 over 60 h’ uninterrupted electrolysis. This work provides a promising strategy to develop highly efficient and robust electrocatalysts for the consecutive production of high-value products coupled with green H2 production.
Multifunctional nanoporous biocarbon derived from ginger: a promising material for CO2 capture and supercapacitor
Authors: Davidraj Jefrin M.
Published: January 2025

Nanoporous activated carbons derived from bio-waste are gaining consideration due to their exceptional potential for energy storage and CO2 adsorption. Herein, we put forward a straightforward, low-cost method for preparing a highly efficient nanoporous biocarbon from ginger using solid-state activation approach. Ginger was pyrolyzed at various temperatures before activating using different amounts of KOH as an activator to produce nanoporous biocarbon. The prepared samples possess high specific surface areas and large pore volumes. By simply adjusting the pyrolysis temperature, the microporosity and surface oxygen functionalities can be finely tuned. The best sample exhibits a high Brunauer-Emmett-Teller-specific surface area of 2,330 m2/g and a large pore volume of 1.10 cm3/g and offers excellent specific capacitance of 244 and 119 F/g when tested in a three-electrode and two-electrode, at a current density of 0.5 A/g. Additionally, the optimized material demonstrates a high CO2 uptake capacity of 4.87 mmol/g at ambient pressure and 25.8 mmol/g at 0 °C and 30 bar. These interesting adsorption and energy storage performances of the nanoporous biocarbon underscore the potential of converting food waste into high-performance CO2 adsorbents and supercapacitors.
Identifying the pedoclimatic conditions most critical in the susceptibility of a grapevine cultivar to esca disease

Published: January 2025

Esca, one of the most destructive grapevine trunk diseases, is still poorly understood. As grapevine cultivars vary widely in their susceptibility to esca, we designed a four-year experiment to identify the environmental factors that influence the expression of the disease in a susceptible cultivar. We collected epidemiological and physiological data once a year for four consecutive years in 19 vineyard plots located in four wine-growing regions of Western Switzerland. We compared these data with climatic data obtained from weather stations for these same plots for four years and over the long term. We also estimated the soil water holding capacity of each plot. Confounding factors were minimal because all vineyards were planted in 2003 with the same cultivar and all plants grafted in the same nursery with genetically homogeneous grafting material. Principal component and regression analyses of combined epidemiological, biotic and pedoclimatic data identified a positive correlation between soil water retention capacity and plant mortality due to esca. These analyses also showed that leaf disease symptoms and apoplexy are more frequent when cold and wet periods are followed–or alternate with–hot and dry periods, and that apoplexy occurs more frequently when weather conditions change abruptly (a cold and wet May followed by a hot June) and deviate significantly from long-term climatic conditions. Regression analyses show that the soil water holding capacity impacts less the disease expression when the climate is warm and dry, both at the regional and year-specific levels. Having identified the most important environmental factors towards the expression of esca, this study allows recommendations to be given to the winegrowers for the cultivar studied but can also be used as a model to identify the environmental factors that influence the expression of fungal diseases in other grapevine cultivars and other grapevine trunk diseases.

Fossil energy has a limited amount and is not renewable. Therefore, renewable energy sources are needed so as not to depend on fossil energy sources. This study aims to evaluate the effect of the type and percentage of adhesive material used, on the compressive strength and durability of durian peel briquettes.  The main material used in making briquettes is durian peel. The adhesive material used is star fruit leaves with a percentage of 0%, 2%, 4%, 6%, 8%, and 10%. In this study, characterization tests were carried out on the briquettes produced with reference to ISO 17225-1 and ASAE S 269.4. The results showed that the best compressive strength value with 0% adhesive concentration (8.51kg/cm2) and the best durability value with 8% adhesive concentration (92.7%). Based on the test results, it is known that the addition of adhesive material causes the compressive strength value and durability value to decrease.

Published: January 2025

Indonesia is an archipelagic country with an ocean area wider than land. Indonesia's ocean areas contain many maritime activities, one of which is shipping and trade. This activity causes a lot of domestic and foreign transportation to pass through Indonesia's maritime areas. It is not uncommon for domestic and international sea transportation to discharge exhaust emissions from their fuel onto the sea surface, causing marine damage. This article was created with the aim of summarizing previous research to make it easier for readers and to find out the appropriate types of maritime chemical fuels, combustion and exhaust emissions, as well as reducing pollution from combustion. The review of studies uses a comparative approach, collecting sources from Google Scholar and PubMed databases, as well as national and international publications. The research results show that liquefied natural gas (LNG) and hydrogen are good candidates to replace chemical fuels because they are both sulfur-free.

Biodiesel is a renewable energy source that has great potential as an alternative fuel to replace fossil diesel in diesel engines. The potential of feedstock from non-edible oils for biodiesel is being considered with the aim of biodiesel production without negatively impacting food issues. Nyamplung oil is a type of non-edible oil in nature that can be used as a source for biodiesel esterification. This research aims to produce methyl ester from nyamplung oil using Zirconia-embedded natural zeolite catalyst (ZrO2/natural zeolite). The catalyst used was prepared from natural zeolite by impregnation method. The results showed that the free fatty acid conversion was obtained at 89.0% which was achieved at a temperature of 60°C in 80 minutes, a catalyst concentration of 5% wt. of the oil, and a molar ratio of methanol to oil at 9:1 for biodiesel production. The results of this study indicate that ZrO2/natural zeolite catalyst is used to produce biodiesel from nyamplung oil.

In this study, synthesis of a sodium alginate-coated rice husk-based biocomposite as a substitute adsorbent to lessen the negative impacts of Congo red dye was conducted. A calcium chloride (CaCl2) solution was used in the sonication and encapsulation processes to produce the biocomposite material. X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and Fourier Transform Infrared (FTIR) Spectroscopy were used to characterize the biocomposite material. Adsorption experiments showed that the optimum pH was 3 and the dye concentration was varied between 10 and 50 ppm and adsorbent mass between 0.05 and 1.5 grams. Adsorption kinetics followed the pseudo-second-order linear model, while the adsorption isotherm model matched the Freundlich model. According to these results, biocomposites of rice husk and sodium alginate has a potential to be an environmental-friendly way to manage the textile waste.

Published: January 2025

The green chemistry technique was carried out for the very first time to synthesize copper nanoparticles (Cu-NPs) by applying CuSO4 as a precursor and red dragon fruit peel extract as a reducing agent. The extracting procedure of red dragon fruit peel was conducted by maceration technique with solvent of methanol. Cu-NPs were produced through green chemistry by the reduction method. Cu-NPs were prepared by combining CuSO4 solution with red dragon fruit peel extract in the compositions of 1:1, 1:2, 1:3, 1:4, and 1:5. The successfully synthesized Cu-NPs were analyzed using Scanning Electron Microscopy (SEM), Particle Size Analyzer (PSA), and UV-Visible Spectrophotometer. The variation in the volume of reducing agent affect the maximum wavelength produced. The optimum concentration of reducing agent (1:5) shows the highest intensity at 650 nm. The optimum pH for the synthesis of copper nanoparticles (Cu-NPs) with dragon fruit extract was 6. Cu-NPs were stable at 20 minutes to 1 hour. From the SEM figure of Cu-NPs, it can be observed that the particles are of round shape. Volume or weight analyzes of Cu-NPs employing PSA provided particle diameters between 80 and 120 nm with an approximate distribution of 100 nm.

Authors: Isnaini Nur
Published: January 2025

The FTIR UATR method for quantifying caffeine in green tea samples was validated. ATR (Attenuated Total Reflectance) , a technique for direct analysis without sample preparation, was employed. Caffeine was determined at peak absorption between 1600 and 1700 cm-1. Calibration using standard concentrations from 0 to 5% yielded excellent linearity with a correlation coefficient value of 0.9978. Precision, measured as % RSD (2.8369%), met the acceptable limit of 2/3 the Horwitz CV (4.5323). Accuracy was confirmed through spiking, resulting in a recovery of 100.3%, within the acceptable range of 95-105%. These findings demonstrate the suitability of this method for caffeine analysis in green tea samples.
