O estado da arte contemporânea acerca dos estudos do corpo e seus paradigmas nas primeiras décadas do século XXI
Authors: Baptista Tadeu João Ribeiro
Published: February 2025

Resumo O corpo é um tema recorrente em diversos campos de conhecimento, entre eles a filosofia, a história e a educação. As concepções de corpo tendem a ser analisadas na produção bibliográfica, pois expressam o modo como os autores podem refletir sobre a relação do ser humano consigo, com outros e com a natureza. Desse modo, o problema desta pesquisa é identificar quais são as suas abordagens epistemológicas predominantes entre 2001 a 2018. Como metodologia, realizou-se um estudo com características bibliométricas, de caráter quanti-qualitativo, em periódicos da área da Educação de 2001 a 2018, considerados como presentes no estrato A-1 do Qualis CAPES (2013-2016). Como objetivo geral do estudo, procurou-se examinar as concepções de corpo em periódicos brasileiros do campo da Educação, aproximando-se dos paradigmas de teorias científicas principais. Os objetivos específicos incluem, a) verificar o movimento da produção de conhecimento sobre o tema no período de tempo estudado; b) identificar os autores que mais publicaram temas relacionados ao corpo em revistas da Educação; c) analisar como o debate epistemológico sobre o corpo se desenvolveu quantitativamente e; d) apresentar como as concepções de corpo se manifestam nos diferentes textos analisados. Os resultados demonstram que entre as revistas estudadas há uma predominância de concepções fenomenológicas, seguidas do movimento pós-moderno, do positivismo e do materialismo dialético, respectivamente. Como conclusão, é possível dizer que a tradição fenomenológica se destaca nos textos pesquisados, demonstrando certa preocupação de se olhar para o ser humano como uma totalidade.
Experimental investigation of the strut efficiency factor of bottle-shaped struts on local models and reinforced concrete deep beams

Published: February 2025

Abstract The design of concrete structural elements with discontinuous stress distribution is often done using strut and tie models and involves the design and detailing of reinforcement, as well as verifying the strength of struts and nodal zones. Simplified design approaches restrict the effective stress on a strut below design limits, depending on the strut efficiency factor, established based on the experimental evidence available, comprising tests on full-scale structural members and partially loaded concrete prisms. This paper presents the results of tests on reinforced concrete deep beams and partially loaded hexagonal concrete struts to investigate the strut efficiency factor of bottle-shaped struts. The similarities and differences in terms of response and resistance are discussed. Results show significant differences in behaviour and strut efficiency factor between the hexagonal local models compared to tests on deep beams, evidencing that local models are not representative of the strength of bottle-shaped struts of full-scale reinforced concrete structural members.

A GARANTIA DOS DIREITOS FUNDAMENTAIS E O CONTROLE DA VIOLÊNCIA NOS TERRITÓRIOS: uma análise a partir da teoria do biopoder de Foucault
Authors: Mendes Larissa Sousa , Oliveira Ana Clara Nascimento , Marques Filho Elvis Gomes , Figueiredo Luciano Silva
Published: February 2025

O presente artigo se propõe a contribuir com uma reflexão interdisciplinar sobre o problema da violência, a relação entre os dispositivos securitários contemporâneos no Brasil e a violação dos direitos fundamentais preceituados na Constituição Federal de 1988, a partir da reflexão da teoria política de Michel Foucault (1975) com base em uma proposta de correlação com o pensamento de Milton Santos (1996) tendo como fundamento a concepção do uso da técnica/norma como mecanismo disciplinar da sociedade e do território. A metodologia utilizada para a efetivação dos objetivos do presente estudo está fundamentada em uma pesquisa bibliográfica conforme preceituado por Gil (2002). Assim, no que concerne aos teóricos que dão sustentação à pesquisa, foi utilizado como principal referência, no campo da Teoria do Biopoder, os trabalhos de Foucault (1989; 1975). Quanto à Teoria do Espaço Geográfico e o conceito de Território, a pesquisa foi fundamentada nos trabalhos de Milton Santos (1988; 2005; 2006). No tocante à segurança pública, como exemplo empírico de dispositivos de segurança que ferem garantias fundamentais, a pesquisa apresenta o uso de tecnologias de reconhecimento facial, essa técnica, a própria coleta em si, de tais dados de biometria, e seu armazenamento, constituem indícios de violação do direito à privacidade. Conclui-se, assim, que o monitoramento, para fins de segurança pública, de pessoas inocentes é, inclusive, interpretado por pesquisadores como uma violação ao princípio da presunção de inocência, uma vez que toda investigação que restrinja direitos deve partir de uma suspeita fundada.

Considerations when assessing urban South African children with the Developmental Test of Visual Perception 2nd edition (DTVP-2)
Authors: Smith Mariska , Visser Marieta , Van Heerden Rita , Raubenheimer Jacques
Published: February 2025

Background: Occupational therapists  in South Africa (SA) use visual perceptual measurement instruments standardised in other countries. The Developmental Test of Visual Perception 2nd edition (DTVP-2) is frequently used by OTs in SA, although its suitability is questioned regarding its use among the population of children in SA. A later version of the test (DTVP-3) has become available in 2013.
Methods: This article reports on a quantitative, descriptive investigation into the suitability of the DTVP-2 for English-speaking children aged 5 years and 6 months to 5 years and 11 months, from the City of Tshwane (COT) in SA. One hundred and thirty-four (134) children were selected from English Language of Learning and Teaching (LOLT) schools in the COT. The motor-enhanced subtests of the DTVP-2 were administered according to the prescribed method, and the motor-reduced subtests were administered with an adapted stop rule method.
Results: The findings showed that the DTVP-2 scores of the SA children varied from the American normative sample, with differences observed mostly in the visual closure, visual-motor speed and form constancy subtests. More accurate results were found in the visual closure subtests when the prescribed stop rule was excluded.
Conclusion: The DTVP-2 should be used with caution to measure children's visual perceptual skills. Alternative measurement instruments should be used or specific instruments more suitable for the South African context need to be developed by local occupational therapists.

Published: February 2025

The necessity to investigate alternative energy sources with substantial potential has been highlighted by the world's dependence on fossil fuels for energy production. Prioritizing sustainable energy solutions is imperative in light of the current energy dilemma, which is made worse by a growing population and depleting fossil fuel supplies. Recent decades have seen significant advancements in biofuels, including biodiesel, bioethanol, and biohydrogen. These biofuels, which are made from inexpensive, renewable resources including plant, microbial, and algae biomass, present a hopeful future. Governments throughout the world, including India, are working to increase their capacity to produce renewable energy. The biggest obstacles to the broad use of biofuels, however, continue to be their expensive production costs and the labor-intensive procedures required. The unique physicochemical properties of nanomaterials, such as high surface area, catalytic activity, and tunable electronic characteristics, enable breakthroughs in energy conversion processes. With its distinct benefits for the production of biofuel, nanotechnology has become a game-changing solution. Nanomaterials' unique structural characteristics and nanoscale size have greatly increased the efficiency of biofuels and accelerated the transformation of waste into energy. This paper examines the latest developments in the application of different nanoparticles, the difficulties in doing so, and the potential of nanotechnology in the manufacture of biofuels in the future.

Published: February 2025

In different studies on the impact of fuel blends on the performance and polluting emissions of an internal combustion engine, it is necessary to identify some physical and chemical properties that allow understanding of the behavior of the results; however, obtaining such properties requires the use of special equipment that may incur additional costs. In this document, from some experimental tests, it has been possible to obtain the behavior of physical and chemical properties (density, boiling temperature, cetane index, kinematic viscosity, heat values, and adiabatic flame temperature) for different commercial diesel and palm oil Biodiesel blends. Additionally, the data obtained were statistically treated to obtain fit equations that predict the behavior of most of the properties studied for blend percentage values different from those tested.

THE RETURN OF ILLEGAL MIGRANTS AS A STRATEGIC TASK FOR THE IMPLEMENTATION OF THE STATE POLICY OF UKRAINE IN THE FIELD OF INTEGRATED BORDER MANAGEMENT
Authors: Mota Andrii
Published: February 2025

Illegal migration remains a widespread problem. Among a wide range of various ways of solving it, the final migration result can guarantee the return procedure. Their relevance is related to the introduction of an effective border policy as a tool for creating a territory of freedom, security and justice with respect for basic human rights.The meta-study of the return of illegal migrants took place in its established purpose and the current status of legal regulation in the general system of integrated border management.The return of illegal migrants is characterized taking into account methodological approaches about the obligation of coercive measures, the relationship with the protection of the state border and the humanization of its implementation. Systemic-structural and functional methods contributed to the study of the status of subjects authorized to ensure forced return and reproduction, regulatory and legal provision of cooperation in the implementation of coercive measures against foreigners and stateless persons. The comparative legal method was used to characterize the social conditioning of the application of return to combat illegal migration in different socio-political conditions in comparison with the foreign experience of border management.Conducting the forced return and removal of foreigners (stateless persons) of the object also characterizes the administrative and jurisdictional content of the procedural activity. Making a decision on the application of return has been transferred to the purely administrative sphere of competence of individual bodies, in particular, state border protection bodies. Judicial control is carried out for the detention of illegal migrants with the provision of enforcement of diversion.The evaluation of the effectiveness of the return policy of illegal migrants is based on the indicators of the fulfillment of the goals of the integrated border management strategy. It is proposed to highlight the legal, qualitative and psychological components of such efficiency.
THE IMPORTANCE OF HUNTING ARMOR AND MILITARY PREPAREDNESS IN ENSURING NATIONAL BORDER SECURITY
Authors: Korklis Andrejs , Mikažāns Arvils
Published: February 2025

Hunting is a widely practiced activity around the world, as humans have been hunting since the dawn of civilization, continuously refining their skills, techniques, and methods. Hunting, or the pursuit and killing of wild animals, requires hunters to be adept at camouflage, accurate shooting, navigating the terrain, and reading tracks left in the forest. In essence, hunting involves skills that are also valuable in military contexts, especially for small combat units (such as commandos or snipers). Hunters are among the most knowledgeable about the forests of Latvia and could potentially operate individually or in small groups behind enemy lines in times of national threat. There are approximately 25,000 hunters in Latvia, making up about 1.3% of the population. Many hunters are also serving in the National armed forces, the National guard, the police, and the Border guard.The purpose of the study: Analyze the armament available to Latvian hunters, the level of military training in hunting associations and the possibilities of involving hunters in ensuring border surveillance.Main tasks:1. Study the armament and military training of Latvian hunters;2. Analyze the possibilities of using hunters in ensuring the security of the border;3. Make proposals in which way it would be possible to use hunters in ensuring the security of the land border.Research methods:1. Empirical research method (survey);2. Qualitative research method (situation analysis);3. Method of logical analysis.
Alternative treatment strategies for bacterial vaginosis that include the use of lactic acid as a potential solution to the problem of antibiotic resistance
Authors: Minakova Alena D. , Dzhibladze Tea A. , Zuev Vladimir M. , Khokhlova Irina D.
Published: February 2025

BACKGROUND. Bacterial vaginosis is a common infectious non-inflammatory vaginal disease that increases the likelihood of contracting sexually transmitted infections, which has a negative impact on perinatal outcomes and generally reduces the quality of life. Given the low long-term efficacy of antibiotic therapy, as well as the high recurrence rate and side effects associated with antibiotic use, there is a need to find alternative approaches to its treatment.
AIM. To evaluate the efficacy and tolerability of a comprehensive two-stage treatment of BV including clindamycin or dequalinium chloride and lactic acid in women of reproductive age.
METHODS. An open randomized clinical study was carried out, which involved 54 women aged 18 to 45 years with a diagnosis of bacterial vaginosis confirmed by Amsel's criteria. The participants were randomly assigned into three groups: 17 women from the first group used lactic acid, 20 women from the second group used a combination of clindamycin and lactic acid, and 17 women from the third group used dequalinium chloride with lactic acid. Treatment efficacy was evaluated after 14 days using Amsel's criteria. Three months after the completion of treatment, complaints were assessed and vaginal pH was measured.
RESULTS. During the study, it was noted that two weeks after the completion of treatment, whitish-gray vaginal discharge ceased in all women from the second and third groups. In the first group, where only lactic acid was used, discharge continued in three patients. Positive dynamics in the pH change of vaginal secretions were observed in all groups both two weeks and three months after the end of treatment, with the most noticeable effect in women using dequalinium chloride together with lactic acid. Three months after the end of treatment, complaints of vaginal discharge persisted in two women from the first group and two from the second group.
CONCLUSION. The conducted study confirmed the high effectiveness of two-stage treatment. However, the combination of dequalinium chloride and lactic acid demonstrated more stable results in both the short and long term, making this method of non-antibacterial therapy the most preferable in the context of the growing problem of antibiotic resistance.

Since the first in vitro fertilization (IVF) procedure, assisted reproductive technology (ART) has helped many patients in the treatment of infertility. However, as for 2022, according to the data of Russian Association of Human Reproduction the success rate of IVF is still below 50%. Morphological assessment of blastocyst quality still remains the gold standard. To an extent, implantation rates have increased through the selection of high-quality embryos. Although, due to the subjective nature of the morphological assessment, further research is needed to establish the associaton between the reproductive potential of embryos and their morphology. A time-lapse system combined with artificial intelligence (AI) capabilities can improve the assestment objectivity and detect new morphological signs of blastocyst quality. Preimplantation genetic testing is an effective but expensive, and invasive procedure, therefore, the development of faster and non-invasive techniques is needed. Detection of exosomes, proteins, and metabolites that are released during blastocyst development into the culture medium can help determine blastocyst ability to implant, because oposed to genes, said biomarkers provide more accurate information about the embryo physiological state, and interaction with its environment. This review provides information on the morphological and biochemical characteristics of blastocyst quality, their association, as well as the use of AI in embryo selection for transfer.

Published: February 2025

The devastating 6 February 2023 Kahramanmaraş earthquake sequence in southeastern Türkiye started with a moment magnitude (Mw) 7.8 earthquake, for which the initial rupture broke the Sakçagöz segment near Nurdağı and then jumped into a bilateral rupture along multiple segments of the Eastern Anatolian fault zone (EAFZ). This complicated rupture was followed nine hours later by an Mw 7.6 event near Ekinözü. To better understand the spatiotemporal evolution of aftershocks, site amplification, and the structural and tectonic framework of the EAFZ in this diffuse triple junction, we deployed a dense seismometer array covering both aftershock zones for nearly four months. The main Eastern Anatolian Seismic Temporary (EAST) array includes 125 nodal, 10 broadband, and 6 strong-motion seismic stations distributed around the rupture zone. An additional linear array of 73 nodal stations was also installed across the Pazarcık segment of the EAFZ and the Sakçagöz segment near the Mw 7.8 epicenter to record fault-zone waves for ∼30 days. This article shows example recordings and the EAST array geometry, preliminary research results, and the metadata related to all of the stations in this array. A deep-learning-based phase picking for one month of continuous recording yielded millions of seismic phase readings and tens of thousands of aftershock locations after phase associations. We also give examples of both local and teleseismic waveforms recorded by the nodal arrays, which can be used for subsequent high-resolution earthquake relocation, imaging of crustal structures, and fault-zone imaging.
Nonseismic Short-Duration Events Offshore Cascadia: Characteristics and Potential Origin
Authors: MacLeod Leo M. F. , Wilcock William S. D.
Published: February 2025

Ocean-bottom seismometers (OBS) often record nonearthquake signals termed short-duration events (SDEs) that are typically recorded on one station with durations of ∼1 s and frequencies between 4 and 30 Hz. Their origin has been attributed to animals bumping the sensor and a variety of physical mechanisms, including the passage of methane bubbles through sediments and across the seafloor. We analyzed records from OBSs deployed on the Cascadia margin and Juan de Fuca plate for the occurrence and characteristics of SDEs. SDEs are observed on all OBSs at rates that vary by over two orders of magnitude. The rates vary significantly at any given depth but on average decrease with increasing depth. The rates are low on buried sensors. For some unburied sensors, the rates are dependent on diurnal and/or tidal cycles. Strongly diurnally dependent rates for several OBSs on the continental shelf and upper slope with more SDEs during the day, are evidence of a biological mechanism for some SDEs. The presence of SDEs on buried sensors requires a physical mechanism for others. Because the decrease of SDE rates with depth is broadly consistent with both the expected variation in benthic animal densities and the emission of methane bubbles from the seafloor, it is not possible to infer the relative importance of biological and physical mechanisms. Experiments with cameras observing the sensor could be supported by cabled observatories and would provide a means to address this issue.
Gender Self-Concept and Its Relationship with Physical Fitness in University Students
Authors: Masagca Ramon Carlo
Published: February 2025

This study explores the relationship between gender role self-concept and physical fitness among 362 collegiate students from a state university in the Philippines. The participants were selected through random sampling, and the Traditional Femininity-Masculinity scale was used to measure gender role self-concept. Various fitness tests, including the one-minute push-up, wall sit, plank, sit and reach, and three-minute step test, were employed to assess muscular endurance, flexibility, and cardiorespiratory fitness. The International Physical Activity Questionnaire was used to measure physical activity levels. Data were analyzed using linear regression, with gender role self-concept as the independent variable and muscular endurance, flexibility, cardiorespiratory endurance, and physical activity levels as dependent variables. The results indicated that masculine gender role self-concept significantly predicted muscular endurance and physical activity levels in both males and females. Specifically, in females, core muscular endurance and physical activity levels were associated with masculine gender role self-concept, while in males, these traits predicted upper limb endurance and physical activity levels. The study highlights the importance of promoting physical fitness beyond traditional gender norms, advocating for a focus on individual inclinations and motivations within an inclusive environment. It also suggests that future research should incorporate qualitative methods to provide a deeper understanding of gender roles in physical fitness, ensuring that fitness strategies are both inclusive and equitable.

Published: February 2025

This study investigated the influence of perceived instructor emotional support on academic resilience among 363 first- and second-year university students enrolled in Physical Education (PE) courses at a State University in the Philippines. Using the Teacher Emotional Support (TES) Scale and Academic Resilience Scale (ARS-30), the research focused on three components of emotional support: Positive Climate (PC), Instructor’s Sensitivity (IS), and Regard for Adult Perspective (RAP). The findings revealed a significant relationship between TES and ARS, with IS and RAP influencing students’ ability to persevere through challenges. However, PC did not show a statistically significant influence on resilience. Regression analyses indicated that IS fostered resilience by addressing students’ emotional needs, while RAP enhanced autonomy and engagement by valuing students’ perspectives. These results underscored the importance of emotional support from PE instructors in creating inclusive environments that fostered student resilience. The study contributed to a growing body of literature emphasizing the critical role of university instructors in shaping students’ academic success and well-being. Practical recommendations included the need for professional development programs to equip PE instructors with strategies to provide adequate emotional support. Despite the limitations of a single institution sample, this research offered valuable insights into fostering resilience in higher education, particularly in contexts where academic and emotional challenges intersected. Future research was recommended to explore diverse educational settings to validate these findings and examine additional factors, such as socioeconomic status, that might have mediated these relationships.

This study examined the roles of grit and curiosity in predicting academic engagement among physical education students at a selected state university. Using quantitative methods with a sample of undergraduates enrolled in Physical Activity Toward Health and Fitness courses, it assessed the influence of these psychological traits on academic engagement. The results showed that grit significantly predicted academic engagement, highlighting its importance in fostering perseverance and sustained effort. However, curiosity alone did not significantly influence engagement, though combined with grit, it contributed to a more profound interest in learning. The study acknowledged limitations such as focusing on a single university and potential bias from self-report measures. Despite these limitations, the research added valuable insights specific to this studied context, indicating that educational strategies should aim to develop both grit and curiosity to enhance student engagement and performance in physical education and other academic areas.

Se llevó a cabo una revisión exhaustiva de la literatura en bases de datos académicas incluyendo PubMed, Scopus y Google Académico.  La búsqueda se restringió a estudios publicados entre 1987 y 2022 para asegurar la inclusión de investigaciones actuales. Se revisaron artículos en inglés y en español para abarcar la mayor cantidad posible de literatura disponible sobre el tema. En total, se analizaron 24 artículos que proporcionaron una visión comprensiva de las variables antropométricas y su influencia en el rendimiento de los ciclistas. Para ciclistas de pista, el desarrollo de masa muscular en las piernas es fundamental para generar la potencia explosiva en Sprint y pruebas cortas, requiriendo ejercicios de alta intensidad. En cambio, para ciclistas de ruta, un alto VO2max y bajo porcentaje de grasa corporal son claves para el rendimiento en pruebas largas, y es crucial combinar entrenamientos aeróbicos con estrategias para mejorar la relación potencia-peso y la eficiencia aerodinámica.

Authors: Celso Rafael T.
Published: February 2025

The study aimed to compare three energy drink timings on the front crawl performance of 60 collegiate swimmers selected through purposive sampling. Specifically, participants consist of 30 females (50%) and 30 males (50%) equally distributed across three groups—Group 30, Group 40, and Group 1h—each containing ten females (16.67%) and ten males (16.67%), making up 33.33% of the total participants per group. Group 30 includes the participants who have 30 minutes of energy drink consumption timing prior to the testing. Group 40 has 40 minutes of energy drink consumption timing. Lastly, Group 1h includes the participants with an hour as their consumption timing. The study's instrument consists of a time trial of 50m, 800m, and 1500m front crawl performance recorded using a handheld stopwatch. The data gathering commenced after 30 hours of caffeine cessation for the participants. After this, each participant consumed a commercially available energy drink. The different energy drink consumption timings were implemented before administering the front crawl performances. Another 30 hours were observed to wash out the effects of the prior testing. The second testing commenced with the same protocol until the three front crawl performances were done. The data from the time trials were analyzed for differences through the Kruskal-Wallis H test. The between-group comparison of all participants for front crawl performance showed no significant differences in 50m, 800m, or 1500m events (P > .05). Similarly, male participants exhibited no significant differences across groups in all events, with P values for 50m, 800m, and 1500m events being (.90), (.17), and (.35), respectively. Female participants also showed no significant differences between groups, with P values of (.69), (.65), and (.31) for the 50m, 800m, and 1500m events, respectively. The study found no significant difference in the effects of consuming energy drinks at 30 minutes, 40 minutes, and 1 hour on 50m, 800m, and 1500m front crawl swimming performance, regardless of the swimmers' sex. Future studies were suggested to replicate the study for validation.
Perception of physical activity vs. actual fitness: a comparative study in pathfit 1 students
Authors: Mendizabal Bengie
Published: February 2025

The study aims to investigate subjective physical activity as a predictor of selected health-related physical fitness. The study included 362 collegiate students from a state university in the Philippines, composed of 199 males and 243 females. The respondents were selected through a combination of stratified and random sampling. The respondents were asked to complete the International Physical Activity Questionnaire (IPAQ), which was the instrument to quantify subjective physical activity. Also, the fitness data from the PatHFit 1 course, to which the participant belonged, was collected. As for the selected health-related physical fitness components, flexibility was measured through a sit-and-reach test. Muscular endurance was quantified using three fitness tests: a one-minute push-up test, plank test, and wall sit test. Lastly, a Three-minute step test was used to quantify the cardiovascular endurance of the respondents. Upon collecting the necessary data for the investigation, linear regression was used for data analysis. The study found that subjective physical activity assessments using the IPAQ effectively predicted muscular endurance and flexibility. As for sex specificity, Subjective physical activity levels notably influenced upper body and core endurance in males. However, only muscular endurance was affected in females. The findings highlight the need for further studies using various fitness assessments to validate the study results and explore the broader relationship between perceived activity and fitness across the genders.

Aspergillus parasiticus, the causative agent of Aspergillus cob rot, and Mucor circinelloides, which causes Mucor stem rot, are types of pathogenic fungi that have the potential to reduce the quality of corn (Zea mays L) harvests. An effective and environmentally friendly approach to control these pathogens is to use biological agents, such as Trichoderma harzianum. This study aims to evaluate the inhibitory potential of T. harzianum against A. Parasiticus and M. circinelloides using antagonism tests with dual culture methods in vitro. The parameters used in this study were measurements of the percentage of the inhibition rate of the biological agent T. harzianum against pathogenic fungi. The results of the antagonism test showed that the biological agent T. harzianum had moderate inhibition against A. parasiticus and M. circinelloides with the percentage of each inhibition during the five days incubation period are 32.5% and 42.38%. This indicates that T. harzianum has the potential as a biological agent in controlling A. parasiticus and M. circinelloides in corn plants.

Acid soil is widely available in Indonesia and is suboptimal, so yields are low. The research examines the effect of antagonism and nitrogen fertilizer on peanuts' growth, nodulation, and yield in sour planting. This study used a factorial complete randomized block design with two factors. The first factor is the dose of Nitrogen fertilizer with four levels: 0, 50, 100, 150 kg.ha-1. The second factor is the source of rhizobium with three levels: without rhizobium, legin rhizobium dose ten g.kg-1 seed, and rhizobium from peanut plantations. They were repeated three times. Nitrogen 50 kg.ha-1 with the source of used peanut rhizobium showed the highest plant height, 15.73 cm. The combination of 100 kg.ha-1 of nitrogen with a source of used peanut rhizobium showed the highest number of plant leaves, namely 675.33 leaves. A nitrogen dose of 50kg.ha-1  produced the highest effective number of nodules and nodules, namely 363.00 and 19.33 nodules. The optimum nitrogen fertilizer dose is 44 kg.ha-1 for nodule growth. 50 kg.ha-1  nitrogen dose produced the highest number of pods and seed weight, namely 48.67 pods and 407.79 g of seeds. Nitrogen fertilizer at the correct dose can increase peanuts' growth, nodulation, and yield in acid soil. However, a dose that is too high may cause antagonism with the nodulation process and reduced yield.
Assessing Soil Nutrient and Biomass Contributions to Peatland Formation

Peat formation is the main key to carbon sequestration in the Peat Swamp Forest (PSF). The research aims to analyze alternative possibilities for peat formation based on the available soil nutrients and dried biomass. In a complete randomized block design, a factorial trial was applied using two treatment combinations in three blocks: factor A (sampling plots, land cover) and Factor B (dried biomass). Data were analyzed using two-way ANOVA and Tukey Honestly Significant Difference test at a significance level of 5%. A high supply of dried below-ground biomass did not follow the production of rooting litter at high soil nutrients. Most of the biomass was transported upwards into above-ground biomass. All land covers produced above-ground biomass which had the potential to form peat with significant differences for all parameters studied. The potential for peat formation was highly dependent on the various types of land covers (e.g. peat forest), environmental factors, the composition of the seed bank, and the species ability to compete. Restoration actions (revegetation, rewetting, and revitalization) aim to stimulate the development of peat-forming species. The research benefits are expected to enrich PSF's ecological restoration thinking so that PSF can be restored and returned to near its initial condition.
