Published: July 2022

Kerusakan sel-sel endothelial akan mengganggu fungsi pembuluh darah. Gangguan fungsi pembuluh darah merupakan awal penyakit kardiovaskular. Beberapa penyakit kardiovaskular yang dapat timbul akibat gangguan fungsi pembuluh darah, yaitu infark miokard, critical limb ischemia, stroke, gagal ginjal, aterosklerosis, dan penyakit degenerative lainnya. Faktor-faktor penyebab gangguan kardiovaskular di antaranya inflamasi, konsumsi obat-obatan yang berlebihan, konsumsi alkohol, tekanan darah tinggi, kolesterol, trauma, dan pola diet yang tidak sehat.            Tujuan dari penelitian ini adalah untuk mengetahui kadar Circulating Endothelial Cells (CEC) dalam darah pada peserta senam aerobik dilapangan Rampal Kota Malang. Penelitian ini merupakan jenis penelitian deskriptif kuantitatif dan kualitatif. Dalam penelitian ini menggunakan pendekatan kuantitatif. Sampel  penelitian ini adalah 10 peserta senam aerobik. Metode yang digunakan dalam penelitian ini adalah observasi. Instrumen yang digunakan adalah kuisioner dan tes. Penggunaan kuisioner untuk mengetahui aktivitas fisik sehari-hari, umur, status gizi, kebiasaan merokok dan rutinitas latihan. Analisis data dalam penelitian menggunakan uji statistik deskriptif kuantitatif dengan persentase.Peningkatan kadar CEC juga signifikan di pengaruhi oleh tingkat frekuensi latihan senam dalam seminggu. Latihan senam yang tidak dilakukan dengan teratur dalam beberapa bulan menyebabkan proses adaptasi tubuh yang tidak sempurna.

Skin cancer and DNA mutation due to ultraviolet radiation
Authors: Dinle Leila Yusuf Hussein , Zhang Ya Qin
Published: July 2022

Ultraviolet (UV) radiation is emitted by the Sun as well as man-made sources such as tanning beds and welding torches. The process of energy being emitted from any source is known as radiation which can take many different forms, from extremely high-energy radiation like X-rays and gamma rays to extremely low-energy radiation like radio waves. UV photons are in the middle of the electromagnetic spectrum. They have higher energy than visible light but a lower energy than X-rays. It is divided into numerous groups based on the amount of energy they contain. Higher-energy UV photons are included in ionizing radiation, which means they have enough energy to ionize an atom or molecule. Ionizing radiation can cause cancer by damaging a cell's DNA; however, it doesn’t have enough energy to penetrate deep into the body, thus it mainly effects the skin only. UV radiations are considered the most carcinogenic factors which leads to skin cancer. Over $50 million each year is estimated to treat the melanoma skin cancer, but the incidences kept rising each year. The tanning and pigmentation in the skin are the main factors to develop skin cancer that rise concerns about ozone depletion. Continuing research should contribute to an improved knowledge of the genetic and immune suppressive mechanisms involved in the role of the tumor suppressor. Research into skin cancer may help raise consciousness about the harmful effects of UV which leads to improved methods of prevention and treatment of skin cancer.
Awareness regarding prevention and management of needle stick injury among the health care providers in a tertiary care Hospital, Bhubaneswar, Odisha- A qualitative data exploration
Authors: Kar Sonali , Singh Snigdha , Parimita Pragyan , Mishra Alpana , Panda Prem Sagar
Published: July 2022

Needle stick injuries are preventable causes of fearsome diseases like Hepatitis B and HIV. In spite of this knowledge, the health care providers are quite negligent, and the institutional support too is compromised due to the increased demand for services.

The current study is a dipstick audit of the knowledge and practices on NSI (prevention and management) among exposed health care workers, with specific reference to HIV infection in a private health facility in Bhubaneswar city, using an unorthodox tool of Focus Group Discussions among the participants.

: The exercise was a part of the academic activity of health promotion on World AIDS Day 2021. Health care workers such as doctors, paramedical staff & utility staff voluntarily participated in the FGD session. Total 3 FGDs were conducted at 3 different places inside the hospital premises. Three moderators were selected previously and after discussing the theme of World AIDS Day, they guided the FGDs with similar probing questionnaires. The sessions were recorded with the help of a recorder and also noted down along with Sociograms.

The data gave a real picture of how even premier institutions are complacent regarding the problem. Only 27% knew about the SOPs, and in none of the stations,SOPs were displayed or a register was maintained regarding NSI in their work area. None of the participants were aware of Post Exposure Prophylaxis for the same. This indeed highlighted an ignored aspect of quality health care.

The data was an eye-opener in a tertiary care center and from time to time there should be refresher training or sessions to increase the level of awareness.
Procesos cognitivos y ejecutivos asociados a la expresión escrita infantil
Authors: Moreno Cecilia-Beatriz , Korzeniowski Celina , Espósito Adriana
Published: July 2022

Aprender a escribir es clave para transitar con éxito la Educación Primaria. En los grados escolares intermedios se registra un progreso significativo en la escritura infantil, debido al desarrollo lexical y cognitivo. En línea con este postulado, el objetivo del estudio fue analizar el valor predictivo de la atención, percepción, planificación, memoria de trabajo y memoria a largo plazo en tareas de expresión escrita en escolares argentinos. Participaron 168 niños y niñas, entre 8 y 11 años de edad, que cursaban 3er, 4º y 5º grado de Educación Primaria. A partir de un análisis de regresión, se observó que la percepción visoespacial, la memoria de trabajo, la memoria a largo plazo y la planificación predijeron el desempeño en expresión escrita en los niños. La memoria de trabajo denotó un alto valor predictivo, junto con la memoria a largo plazo y la percepción visoespacial. Los hallazgos aportan evidencia sobre la involucración de procesos cognitivos y ejecutivos en tareas de expresión escrita en escolares hispanohablantes. Identificar predictores cognitivos de las habilidades de escritura permite diagramar programas de enseñanza más abarcativos, que contemplen conjuntamente el entrenamiento de las habilidades escritoras específicas y el fortalecimiento de los recursos cognitivos de los aprendices.
Recursos formales en la poesía infantil en español del siglo XXI
Authors: Santiago-Ruiz Eduardo
Published: July 2022

En el siglo XX, la poesía infantil tuvo una gran influencia de la oralidad folclórica. Sin embargo, varios críticos han señalado que, en las primeras décadas del siglo XXI, ha disfrutado de una transformación formal. El objetivo de este artículo es determinar, mediante un estudio literario y estadístico, cuáles son los recursos formales más utilizados en la poesía infantil actual; en específico se analizan el tamaño del verso, la forma general del poema (prosa poética, verso libre y métrica) y el uso de la poesía visual. El corpus de este trabajo consiste en los ganadores del Premio hispanoamericano de poesía infantil y está integrado por 16 libros y 423 poemas. Se encontró que, en la poesía infantil del siglo XXI, la forma más frecuente es el verso libre; se sigue empleando la métrica, pero con muchas innovaciones; es común el uso de varios recursos de poesía visual; y ha comenzado a tomar fuerza la poesía en prosa. En conclusión, se está experimentando un periodo de verdadera renovación formal que apunta a nuevas sensibilidades, estrategias didácticas y formas de lectura.

Authors: Martín-Macho-Harrison Ana , Faya-Cerqueiro Fátima
Published: July 2022

Con el objetivo de explorar la capacidad para cohesionar el discurso escrito en un texto argumentativo que presenta el alumnado al inicio de su etapa universitaria, se analiza el uso de los conectores y marcadores de posicionamiento entre párrafos por parte de estudiantes hispanohablantes de 1º curso de grado. Para ello, se recopila un corpus ad-hoc de textos argumentativos tanto en su lengua materna (español) como en su lengua extranjera (inglés) con una estructura prefijada. La comparación de los datos en ambas lenguas permite identificar transferencia lingüística en su producción escrita. Se confirma que, pese a estar presente en el currículo de etapas preuniversitarias, el uso de conectores como elementos habituales para cohesionar el discurso e introducir nuevos párrafos conlleva algunas dificultades, más evidentes en la lengua extranjera. Los resultados apuntan a la necesidad de un enfoque multilingüe en la enseñanza de este tipo de textos que favorezca la reflexión metalingüística.
Leer la ironía en el libro álbum
Authors: Dueñas-Lorente José-Domingo
Published: July 2022

El libro álbum, constituido por la conjunción de dos códigos expresivos, la palabra y la imagen, supone la gran novedad de la literatura infantil en las últimas décadas. Además, su difusión se expande progresivamente al público adulto. La indefinición del receptor es una de sus características más destacadas, según algunos autores. La combinación de códigos convierte al álbum en un terreno propicio para la ironía. Como es sabido, en el campo de los estudios literarios el concepto de ironía ha sido objeto de muy variadas interpretaciones. Desde fundamentos pragmáticos, analizamos aquí cómo la ironía incide en el sentido final de diferentes álbumes. En todos los casos, cabe establecer unas pautas similares de interpretación. Con ello, se pretende contribuir a que el receptor infantil o el adulto pueda extrapolar a otros álbumes irónicos algunas de las pautas de lectura aquí apuntadas.

Authors: Gutiérrez-Fresneda Raúl , Pozo-Rico Teresa
Published: July 2022

La dislexia es un trastorno específico del aprendizaje de base neurobiológica que afecta a un porcentaje importante de estudiantes. Sin embargo, no se conocen instrumentos validados que contribuyan a la identificación temprana de este problema, lo que dificulta la intervención educativa. El propósito del presente trabajo ha sido elaborar y validar una escala de indicadores de riesgo de la dislexia al inicio de la etapa de Educación Primaria (EIRD-EP) con la finalidad de favorecer la detección de este problema del aprendizaje en los primeros momentos en los que se manifiesta. Se contó con la participación de 458 docentes de Educación Primaria de diferentes centros educativos públicos y concertados. La validez del cuestionario se efectúo mediante la validez de contenido junto a un análisis factorial exploratorio con la mitad de la muestra que indicó una estructura de cuatro factores, posteriormente se llevó a cabo un análisis factorial confirmatorio con la otra mitad de la muestra que demostró un ajuste adecuado del modelo. Los resultados ponen de manifiesto que el instrumento puede ser empleado por los profesionales de la educación para identificar a los estudiantes que se encuentran en situación de riesgo de presentar dislexia.
Hacia la elaboración de un modelo hidrogeológico de la Cuenca del Río Guachiría (Colombia)
Authors: Benavides-Guerrero Carlos Esteban , Caro-Caro Linda Elizabeth , Mariño-Martínez Jorge Eliecer
Published: July 2022

En los últimos años, las variaciones climáticas extremas han generado afectaciones evidentes a los recursos naturales, perjudicando uno de los más importantes: el agua. Un claro ejemplo de ello es la Cuenca del Río Guachiría, ubicada en Colombia; allí, las prolongadas temporadas de sequía de la última década han perjudicado tanto a la biota como a la población civil, ya que dependen principalmente de este recurso. El presente estudio pretende incrementar el estado del arte sobre las variables hidrometeorológicas, hidráulicas y a grandes rasgos, entender las condiciones hidrogeológicas de la Cuenca del Río Guachiría, esto con la finalidad de brindar información que sirva de base para la elaboración de un modelo hidrogeológico conceptual (MHC) que ayude en la toma de decisiones por parte de las entidades encargadas de la gestión del recurso hídrico. En primer lugar, se determinaron las condiciones morfométricas y geológicas del área, encontrando que existe una predominancia de zonas planas con poca pendiente, conformadas por depósitos no consolidados, extensas zonas de inundación e influencia eólica sobre depósitos fluviales. Luego, se realizó un balance hídrico de largo plazo en la cuenca para cuantificar el recurso en la zona; a su vez, se identificaron zonas propicias de recarga en varios sectores: una parte hacia el piedemonte en la zona de altas pendientes y otra hacia los depósitos con influencia eólica, conformados por suelos arenosos y franco arenosos que suprayacen a la Formación Guayabo. Además, mediante pruebas de bombeo, se determinaron diferentes parámetros hidráulicos y se clasificaron los acuíferos como libres, confinados y semiconfinados, ligados a la litología de la zona, por su extensión y complejidad litológica. Finalmente, se realizó un muestreo hidrogeoquímico, donde se encontraron aguas en su mayoría relativamente jóvenes, de poco transporte y con contenidos altos de hierro.
Lo Unheimlich y su capacidad de «detonar» nuestra condición hermenéutica
Authors: Ortega Chacón Orlando
Published: July 2022

A la hora de pensar lo más inmediato a nosotros mismos es necesario acudir a lo que somos en cuanto Dasein. Sin embargo, la experiencia de lo inmediato tiene la condición de presentarse bajo la forma de un extrañamiento, un «no saber». Se verá que la corporeidad y su extrañamiento abren a la posibilidad de una hermenéutica de nuestra propia condición porque la experiencia de lo Unheimlich es una vía de epojé que «detona» (revienta) la cadena de significaciones habitual y reconfigura la experiencia. Se tomará como punto de referencia cuatro casos icónicos: 1) la convalecencia de Oliver Sacks, 2) el famoso caso Paul Schreber, 3) la referencia al joven esquizofrénico en los Seminarios de Zollikon, e incluso 4) el desfallecimiento de Heidegger entre los años 1945 y 1946, todo esto a la luz del extrañamiento de lo íntimo y la posibilidad que este abre a un «reordenamiento interno». En definitiva, las patologías y lo terrorífico que las acompaña son capaces de generar las condiciones de un vitalismo inusitado, pues solo quien se ha enfrentado a la más radical convulsión de todas sus verdades, podrá «abrirse camino» en medio del exceso de donación que desborda su «realidad».

Published: July 2022

This study investigates the influence of historical earnings and historical accrual accounting on projecting future cash flows. The sample consisted of 159 construction, energy, and property development companies from the main capital market of Malaysia. The compiled data of these companies spanned from 2015 to 2019 and was collected from the financial statements of the companies, including operating cash flows and earnings. The profit or loss statement and cash flow statement were used for calculating historic accrual accounting. Earnings, cash flow, and accrual accounting models were used as the basis for the regression model construction. The accounting data demonstrated that the prediction performance of the models was improved by the three-year lag. The previous two-year earnings and accrual accounting had positive and significant predictive power for forecasting future cash flows. Moreover, the past one- and two-year cash flows from operations significantly predicted future cash flows. These results are important for a sound understanding among academics and practitioners of the crux of historical earnings, operating cash flow, and accrual accounting. The findings can assist corporate leaders and management executives in tracking the sustainability and financial growth of an organization.

Published: July 2022

The Olympiad Student Surgical movement historically arose from the activities of student scientific societies at the surgical departments of medical universities and, foremost, departments of operative surgery with topographic anatomy. This is the first department where students are taught future surgical manual skills of a medical specialist. The history of the largest Moscow (All-Russian) Student Olympiad in surgery named after an academician M. I. Perelman, held under the authority of First Sechenov Moscow State Medical University, is more than 30 years. Olympiad Student Surgical movement at Voronezh N. N. Burdenko State Medical University appeared in 2008. A long and difficult path has been covered since then. The teams under the guidance of various lecturers and student leaders experienced ups and downs, repeatedly won victories in the qualifying stages of the All-Russian Olympiad and took prizes in the Finals of the All-Russian Olympiad. In 2015, the tradition of holding an intra-university student Olympiad in surgery was started. Since then, 6 intra-university Olympiads have already been held. This allows annually updating the staffing of the team and encouraging students to even better results. The Olympiad surgical movement has a great pedagogical and educational potential and, undoubtedly, is an important stage in training future medical specialists of a surgical profile.

Introduction. Currently, there are absolute and relative indications for splenectomy in the surgical treatment of gastric cancer.The aim of the study was to improve clinical outcomes of treatment in patients with gastric cancer identifying risks associated with splenectomy, and developing options to correct them. Methods. The study included clinical findings and parameters of the quality of life of 380 patients with gastric cancer who were treated at the Voronezh Regional Clinical Oncological Hospital in 2013-2019. All patients were conventionally divided into 2 groups. The patients of the first group (study group, 172 people) underwent gastrectomy with D2 lymphadenectomy, including splenectomy. The patients of the second group (comparison group, 208 people) underwent spleen-preserving gastrectomy with dissection of lymph node groups 10 and 11. The average follow-up was 39.6 months. In the postoperative period, all patients were examined according to the Clinical Recommendations of the Russian Federation. The SF-36, GSRS questionnaires were used to assess quality of life.Results. Splenectomy increased the incidence of early postoperative complications, including severe complications grades 3 - 5 according to the Clavien-Dindo classification, contributed to the development of reflux esophagitis and, in general, a worsen quality of life in the late postoperative period, but did not affect the patients survival.Conclusion. The data obtained evidence a significantly worse and generally unfavorable safety profile of patients undergoing splenectomy compared to patients who underwent spleen-preserving gastrectomy. Reduced indications for splenectomy appear to be the option to solve this problem. Measures for correction of postoperative complications have been developed for patients with absolute indications for splenectomy.

Currently, the range of hernia types of the anterior abdominal wall is extremely diverse, and their frequency does not tend to decrease, despite the active and widespread introduction of laparoscopic techniques. Concurrently, the surgery of hernias of the anterior abdominal wall is undergoing active and continuous development, due to changing views on the technology of operating this pathology and the principles of anesthetic management. This results in a growing interest in aspects of the development of this industry - from open techniques to minimally invasive endoscopic robotic techniques. However, each surgical method used in the surgical treatment of ventral defects has its own benefits and drawbacks, as well as complications during anesthesia. This article presents an overview of the global experience in the use of laparo- and endoscopic techniques for the treatment of hernias of the anterior abdominal wall, in the context of both - surgical and anesthetic aspects of these operations.

This work is devoted to the study of sensory properties of nanocomposites of electrically conductive polymers towards a number of phosphorus and organochlorine volatile compounds that are simulators of toxic gaseous substances, as well as nitroaromatic simulators of explosive organic substances. Gas sensitivity measurements were performed using an array of chemoresistive sensor microelectrodes covered with thin layers of these nanocomposites. The relative responses was at the level of 4–5%, the detection threshold depending on the type of analyzed toxic substances was from 10 to 100 ppm, the response rate was about 1 minute. The possibility of qualitative identification of toxic and explosive substances in a wide range of concentrations using the methods of statistical analysis of data from the sensory array has been demonstrated.

Published: July 2022

Coronavirus infection (COVID-19) is usually characterized by respiratory symptoms, but can have a wide range of clinical manifestations. The growing interest is focusing on the short-term and long-term immune-mediated sequelae triggered by the COVID-19. One of these complications is post-infectious arthritis, classified by some authors as reactive. This paper summarizes and analyzes 25 clinical cases of COVID-19-associated acute arthritis that have been published from January 2020 to November 2021. The mean age of the patients was 46 14 years, with the disease being more prevalent in men than in women. Joint lesions were mono- or polyarticular, with predominant involvement of the joints of the lower extremities. HLA-B27 antigen was determined in 13 of 25 patients and was found in 30% of cases. Like many other viral diseases, the severe acute respiratory syndrome 2 caused by coronavirus can act as a causative agent or a trigger in the development of inflammatory arthritis in predisposed individuals. The post-infectious arthritis should be differentiated from diseases that can manifest with a similar clinical presentation, which requires a complex of laboratory and instrumental studies. Non-steroidal anti-inflammatory drugs and glucocorticosteroids are successfully used in the treatment. The number of cases of post-COVID-19-arthritis is increasing, which urges further studies of its pathophysiology, diagnosis and treatment regimens.

Published: July 2022

Background: Despite advanced in interventional and medical treatment, mortality after myocardial infarction (MI) remains high, which necessitates the search for predictors of poor outcome. An association between the gene CYP2C19 alleles with lower functional activity and the rates of cardiovascular events has been found. In a number of studies, negative impact of the *2 and *3 alleles of this polymorphic gene on the post-infarction course was shown. However, in most of these studies the patients were followed up from 3 months to 1 year.
Aim: To evaluate the effect of CYP2C19 gene polymorphism (*2, *3) on the long-term prognosis in patients with a history of ST-segment elevation myocardial infarction (STEMI).
Materials and methods: This open-label prospective two-center study included 145 patients aged 45 to 75 years with a history of STEMI. For 1 year from STEMI on, all the patients were taking medications recommended for outcome improvement, such as statins, clopidogrel as a component of dual antiplatelet therapy, beta-blockers, angiotensin converting enzyme inhibitors. The outcomes were assessed at 12 months by the endpoints of cardiovascular death and recurrent non-fatal MI, and at 5 years by the endpoints of overall mortality and recurrent non-fatal MI.
Results: During one year of the follow up, 7 of 145 patients (4.8%) died from cardiovascular causes. Recurrent MI occurred in 8.3% (n = 12) of the patients. The carriers of *1*2 and *1*3 genotypes of the polymorphic CYP2C19 gene were 3.27-fold more likely to experience recurrent MI within 1 year, compared to the carriers of other genotypes (relative risk = 3.27 [95% confidence interval 1.03; 10.36], p = 0.03). After 5 years of the follow up, this association has disappeared. No influence of the assessed polymorphisms on overall and cardiovascular mortality was found (p 0.05). One hundred and seven (107) patients were followed up for 5 years; 14 (13.0%) of them died, other 15 patients (14.0%) had recurrent MIs.
Conclusion: *2 and *3 alleles of the polymorphic CYP2C19 gene responsible for the metabolism of clopidogrel, are risk factors of an unfavorable 12-month outcome after STEMI. Subsequently, the influence of the CYP2C19 gene polymorphism on the outcomes evades and is not associated with a 5-year prognosis. To improve post-STEMI outcomes at 1 year, it is necessary to implement the earliest personalized approached to antiplatelet treatment based on the results of the CYP2C19 gene polymorphism analysis.
U.S. Household Financial Vulnerability: Prediction Analyses in the COVID-19 Pandemic
Authors: Xu Yilan , Yao Rui
Published: July 2022

In this article, we projected household financial vulnerability in the COVID-19 pandemic. Using a nationally representative sample of households from the 2017 Panel Study of Income Dynamics (PSID), we analyzed potential changes in financial status in the pandemic resulting from loss of income and savings from discretionary consumption. We provided a ranking of household groups by their financial vulnerability and the first estimate of the number of households at various degrees of financial vulnerability. Our study showed that a substantial part of the universal stimulus payments was made to households that had sufficient income to cover basic needs and those saved by reducing discretionary expenses. For the most financially vulnerable, the first one-time stimulus payment was too little and too late to help with their financial difficulties. Our findings shed light on to whom and in what form the US government should direct financial assistance during the pandemic.

Technology is becoming embedded in different aspects of agriculture. Specifically, automation of the milking process within dairy production systems represents fundamental change for the operator, the cow herd and indeed the whole farm operation. Adoption of automatic milking requires new thinking for the traditional tasks of feeding, milking and maintaining cow health. The operator needs to change the way in which they manage the dairy business, in assisting the cow in voluntary milking and in interpreting and using data for decision-making and resource management. Automatic milking can bring significant benefits to a dairy business, but it has a high investment cost. If adopted, it is crucially important that its operation is successful. This chapter provides comprehensive information on the different aspects of automatic milking to ensure that the potential benefits of the system are available to dairy farmers and to promote progress of precision farming within dairy communities.

Published: July 2022

In this paper, we introduce a new four-parameter generalized version of the Chen model called the exponentiated extended Chen distribution. Some results about the reliability characteristics of hazard rate function as well as some mathematical properties are provided. The maximum likelihood estimators and five approaches based on the concept of minimum spacing distance estimators are given for estimation of the model parameters and their performances in estimating of parameters are compared by means of Monte Carlo simulations. Also, a multiple regression model with the censored data based on proposed distribution is introduced.

Published: July 2022

In this paper, we study the cardinality constrained mean-absolute deviation portfolio optimization problem with risk-neutral interest rate and short-selling. We enhance the model by adding extra constraints to avoid investing in those stocks without short-selling positions. Also, we further enhance the model by determining the short rebate based on the return. The penalty alternating direction method is used to solve the mixed integer linear model. Finally, numerical experiments are provided to compare all models in terms of Sharpe ratios and CPU times using the data set of the NASDAQ and S&P indexes.
A New Two-parameter Estimator for the Gamma Regression Model
Authors: ASAR YASIN , Algamal Zakariya
Published: July 2022

In this paper, we propose a new two-parameter biased estimator in gamma regression models when there is collinearity among the regressors. We investigate the mean squared error (MSE) properties of the newly proposed estimator. Moreover, we provide some theorems to compare the new estimators to the existing ones. We conduct a Monte Carlo simulation study to compare the estimators under different designs of collinearity in the sense of MSE. Moreover, we provide a real data application to show the usefulness of the new estimator.The simulations and real data results show that the proposed estimator beats other competitor estimators.

Abstrak

Generator merupakan suatu alat yang penting pada sebuah pembangkit yang mengubah energi mekanik menjadi energi listrik. Pemilihan material dalam membuat kerangka penyusun generator sangat perlu diperhatikan agar generator yang dibuat memiliki keefektivitasan yang baik saat dioperasikan. Dampak dari pemilihan material kerangka penyusun generator akan mempengaruhi output generator yang dihasilkan. Secara khusus material aluminium memiliki keefektivitasan yang lebih baik dibandingkan material akrilik. Dari kedua material tersebut didapatkan bahwa material aluminium memiliki distribusi kerapatan fluks magentik yang lebih besar dibandingkan material akrilik sehingga output generator berupa tegangan dan frekuensi juga lebih besar. Hasil uji torsi generator dengan kerangka penyusun aluminium lebih kecil dibandingkan kerangka penyusun material akrilik sehingga kinerja generator dengan material aluminnium lebih baik dibandingkan dengan material akrilik.

Abstract

A generator is an important device in a plant that converts mechanical energy into electrical energy. The selection of materials in making the frame of the generator is very important so that the generator made has good effectiveness when operated. The impact of the selection of the material of the generator's constituent framework will affect the output of the generator produced. Specifically, aluminum material has a better effectiveness than acrylic materials. From both materials it is obtained that aluminum material has a greater distribution of magentic flux density than acrylic material so that the generator output in the form of voltage and frequency is also greater. The result of the generator torque test with an aluminum constituent frame is smaller than the acrylic material building frame so that the performance of the generator with aluminnium material is better compared to acrylic material.
