Published: August 2020

Penelitian ini bertujuan untuk mengetahui dan menganalisis Rasio profitabilitas menggunakan Return on Equity dimana membandingkan antara laba setelah pajak dan Ekuitas dan Rasio Solvabilitas menggunakan Debt To Equty Ratio dimana membandingkan total hutang dengan ekuitas pada PT Adaro Energy Tbk dimana semakin tinggi nilai Return on Equity maka semakin tidak baik perusahaan dalam mengelola modal sendiri untuk menghasilakn Laba begitu juga sebaliknya apabila nilai Return on Equity rendah semakin baik. Sedangkan Debt to Equity Ratio tinggi maka pengelolaan ekuitas tidak baik apabila Debt to Equity Ratio rendah maka penggunaan modal sendiri sangat baik karna tidak mengandalkan pendaanaan dari luar. Penelitian ini adalah penelitian Deskriptif dimana hanya menbandingkan 1 satu variabel saja. Populasi dalam penelitian ini adalah 11 tahun dan sampel dalam penelitian ini selama 9 tahun mulai 2010 sampai tahun 2018 dengan sampling yang digunakan adalah purposive sampling. Uji statistik mengunakan SPSS v 21 dengan teknik analisis data menggunakan metode one sample t-test. hasil penelitian menunjukan bahwa Return on Equity dikatakan baik dan Debt to Equity Ratio dikatakan baik..

Published: August 2020

Actividades como la agricultura, la ganadería, la industria y la urbanización suelen modificar las características físicas, químicas y biológicas de arroyos y ríos y sus riberas. Para evaluarlas se utilizan, por ejemplo, índices de calidad ambiental que surgen de una combinación de parámetros. Estos permiten valorar la calidad ambiental del recurso hídrico por medio de un número, color, una descripción verbal, etc.
El objetivo del presente trabajo fue evaluar la calidad ambiental de los arroyos La Totora y La Carolina ubicados en el Partido de Gral. Alvarado, Provincia de Buenos Aires Argentina, mediante la aplicación del Índice de Calidad Ambiental de la National Sanitation Foundation de Estados Unidos y el análisis de los parámetros fisicoquímicos en los muestreos realizados desde julio de 2016 a junio de 2017.
Al aplicar el ICA-NSF en cada punto de muestreo se halló que la calidad ambiental de los arroyos, en su mayoría, fue mala.

Authors: Figueredo Gustavo Raul , Gutierres Mareva Y. , Spotorno Ruben A. 
Published: August 2020

Los peces son afectados por las temperaturas bajas del agua durante los meses invernales, lo que ocasiona disminución de la tasa de reproducción y de la producción en la acuicultura. Se efectuaron ensayos en dos modelos de estanques, en el primero se colocaron captadores flotantes y el segundo funcionó como testigo. Buscando morigerar los descensos de temperatura del agua, se ensayaron captadores solares flotantes con cubierta de acetato curva. Las experiencias fueron efectuadas bajo las condiciones climáticas del NEA, durante el invierno. El captador solar flotante tuvo una respuesta aceptable respecto al incremento de temperatura buscado. Se presentan las diferencias de temperatura entre las dos piletas de ensayo para los distintos periodos, además de otros parámetros climáticos. Se puedieron conseguir incrementos de la temperatura mínima del agua de 6,2 ºC durante julio y de 8 ºC durante agosto en relación con la temperatura ambiente
Actualidad, indexicalidad y estatus ontológico
Authors: Di Leo Juan Manuel 
Published: August 2020

El presente trabajo tiene como objetivo sostener una posición metafísica conocida como realismo modal que defiende la tesis según la cual el mundo actual y los mundos posibles tienen el mismo estatus ontológico, i.e. la tesis de la pluralidad de mundos (Lewis, 1986: 104). Para ello debo mostrar que la tesis de la indexicalidad de la actualidad puede sostenerse. En este sentido dividiré el trabajo en cuatro apartados: en el primero haré una reconstrucción de los principales argumentos en favor de dicha tesis. En el segundo analizaré algunas objeciones hechas por Barrio (1999), centrándome en la afirmación según la cual el realismos modal no puede dar cuenta de la diferencia entre “existir” y “existir actualmente” sin caer en una argumentación circular o suponer lo que debe probar. En el tercero propondré tres contra argumentos a las objeciones de la sección anterior, el argumento modal, el ontológico y el epistémico. Y por último plantearemos las conclusiones.

Assessment of the acute toxicity, safety and biological activity of lipophilic extracts of the White Sea brown algae– S. latissima and F. vesiculosus– on the model of zoohydrobionts Daphnia magna Straus has been performed.Two methods of obtaining dry lipid concentrate of kelp and fucus were tested. It has been shown that the acute toxicity of the lipid extract of kelp does not depend on the method of its preparation and is about 200 mg/L. The acute toxicity of fucus extract depends on the method of preparation. It is about 100 mg/L in the «cold» method of extraction and increases by an order of magnitude in the «hot» method. To study the biological activity, samples of brown algae obtained by «cold» extraction were used.In chronic experiments, preparations of brown algae were used in a concentration of 8.0 mg/L, which was less than 0,1 LC50 of the acute toxicity of fucus and did not cause toxic effects.For 24 days, the preparations were introduced in contact with Daphnia twice a week. Subsequently, the control and experimental hydrobionts were kept under the same conditions until the death of the last individuals. It has been shown that the preparations of S. latissima and F. vesiculosus in the proposed concentration by 20-30% increased the lifespan of Daphnia in normal conditions and by 50-60% in extreme conditions, while stimulating the reproductive activity of aquatic organisms by 3-4 times. The results obtained suggest that the studied drugs have pronounced adaptogenic and cytoprotective effects.

Background: Increased high blood pressure in the elderly can be caused by various factors, one of which is stress. Stress can trigger the onset of hypertension through activation of the sympathetic nervous system which causes an increase in blood pressure intermittently. Hypertension patients need to be helped to reduce stress so that blood pressure does not increase. One of the non-pharmacological therapies to reduce stress is SEFT therapy. The purpose of this activity are to increase the elderly's knowledge about hypertension and increase awareness to control blood pressure and lowering blood pressure with SEFT therapy. Methods: Method this study is used blood pressure measurement, health education, and SEFT therapy. Results: Of this activity are health education can increase knowledge and awareness in controlling blood pressure, and SEFT therapy can reduce blood pressure in elderly hypertension. Conclusion: SEFT therapy can be an intervention alternative in reducing blood pressure.

Pulau Rambut merupakan satu-satunya situs RAMSAR di Indonesia yang berupa pulau kecil meliputi daratan dan perairan. Keberadaannya sebagai daerah singgahan ribuan burung migrasi dan keanekaragaman hayati daratan maupun perairan yang tinggi. Salah satunya adalah keanekaragaman hayati tanaman bentik tenggelam seperti lamun dan makro alga. Tujuan penelitian ini mengidentifikasi keanekargaan hayati tanaman bentik tenggelam khususnya lamun dengan potensi sebagai bioindikator kesehatan perairan dan potensi karbon biru dalam mitigasi perubahan iklim. Metode penelitian yang dilakukan adalah purposive sampling dengan mengitari dan mengobservasi seluruh pulau dan melakukan transek serta pengambilan sampel baik biomasa dan sedimen pada bulan November 2017. Hasil yang didapat adanya empat jenis lamun yang ditemukan dan enam jenis makro laga. Adanya zonasi antara makro alga dengan lamun di stasiun Pulau Rambut Utara, dan jenis Thalassia hemprichii merupakan jenis kunci lamun di Pulau Rambut dengan nilai indeks penting tertinggi 191 %. Berdasarkan kajian ekosistem lamun sebagai bioindikator kesehatan lamun lokasi bagian utara kondisi perairan sehat dengan sedangkan bagian barat kondisi rusak/miskin. Potensi ekosistem lamun sebagai mitigasi perubahan iklim mampu menyerap karbon dalam stok biomasa lamun sebesar 1,85 MgC/ha. Keberadaan makroalga yang dominan meengindikasikan nutrien perairan yang tinggi jika berlangsung lama akan menyebabkan degradasi dan hilangnya lamun tergantikan dengan makroalga atau sedimen. Diperlukan sistem pengaturan yang terintegrasi mulai dari daratan utama sampai ke laut sehingga keberlangsungan suaka margasatwa Pulau Rambut tetap terjaga.
Ambiguity in high definition: Gaze determines physical interpretation of ambiguous rotation even in the absence of a visual context
Authors: Souto David , Smith Lily , Sudkamp Jennifer , Bloj Marina 
Published: August 2020

AbstractPhysical interactions between objects, or between an object and the ground, are amongst the most biologically relevant for live beings. Prior knowledge of Newtonian physics may play a role in disambiguating an object’s movement as well as foveation by increasing the spatial resolution of the visual input. Observers were shown a virtual 3D scene, representing an ambiguously rotating ball translating on the ground. The ball was perceived as rotating congruently with friction, but only when gaze was located at the point of contact. Inverting or even removing the visual context had little influence on congruent judgements compared with the effect of gaze. Counterintuitively, gaze at the point of contact determines the solution of perceptual ambiguity, but independently of visual context. We suggest this constitutes a frugal strategy, by which the brain infers dynamics locally when faced with a foveated input that is ambiguous.

Authors: Blandina Olivia Asih 
Published: August 2020

The conflict in North Halmahera affects various aspects of community life there. This study aims to find out the influence of ethnoreligious conflict effect on student’s learning motivation in North Halmahera. The sample of this study were students in North Halmahera who was studying at the higher education level. Samples taken as many as 39 people based on a purposive sampling technique. The data were collected using two scales: trauma scale and learning motivation scale. The conclusion from the results of this study is that students from North Halmahera who experienced trauma have wrong learning motivation. This can be seen from the description of trauma measurements that give the results of most (56%) North Halmahera students who study in higher education are in the moderate trauma category, 23% are in the high trauma category, and 21% are in the very high trauma category. On learning motivation, the measurement description results as much as 44% are at a high category, 28% are in the medium category, 23% in the very high category, and 5% in the low category.

Abstract
The Transiting Exoplanet Survey Satellite mission was designed to find transiting planets around bright, nearby stars. Here, we present the detection and mass measurement of a small, short-period (≈4 days) transiting planet around the bright (V = 7.9), solar-type star HD 86226 (TOI-652, TIC 22221375), previously known to host a long-period (∼1600 days) giant planet. HD 86226c (TOI-652.01) has a radius of 2.16 ± 0.08 R
⊕ and a mass of

M
⊕, based on archival and new radial velocity data. We also update the parameters of the longer-period, not-known-to-transit planet, and find it to be less eccentric and less massive than previously reported. The density of the transiting planet is 3.97 g cm−3, which is low enough to suggest that the planet has at least a small volatile envelope, but the mass fractions of rock, iron, and water are not well-constrained. Given the host star brightness, planet period, and location of the planet near both the “radius gap” and the “hot Neptune desert,” HD 86226c is an interesting candidate for transmission spectroscopy to further refine its composition.

Abstract
We have initiated a new survey for local extremely metal-poor galaxies (EMPGs) with Subaru/Hyper Suprime-Cam (HSC) large-area (∼500 deg2) optical images reaching a 5σ limit of ∼26 mag, about 100 times deeper than the Sloan Digital Sky Survey (SDSS). To select Z/Z
⊙ < 0.1 EMPGs from ∼40 million sources detected in the Subaru images, we first develop a machine-learning (ML) classifier based on a deep neural network algorithm with a training data set consisting of optical photometry of galaxy, star, and QSO models. We test our ML classifier with SDSS objects having spectroscopic metallicity measurements and confirm that our ML classifier accomplishes 86% completeness and 46% purity EMPG classifications with photometric data. Applying our ML classifier to the photometric data of the Subaru sources, as well as faint SDSS objects with no spectroscopic data, we obtain 27 and 86 EMPG candidates from the Subaru and SDSS photometric data, respectively. We conduct optical follow-up spectroscopy for 10 of our EMPG candidates with Magellan/LDSS-3+MagE, Keck/DEIMOS, and Subaru/FOCAS and find that the 10 EMPG candidates are star-forming galaxies at z = 0.007–0.03 with large Hβ equivalent widths of 104–265 Å, stellar masses of log(

/

) = 5.0–7.1, and high specific star formation rates of ∼300 Gyr−1, which are similar to those of early galaxies at z ≳ 6 reported recently. We spectroscopically confirm that 3 out of 10 candidates are truly EMPGs with Z/Z
⊙ < 0.1, one of which is HSC J1631+4426, the most metal-poor galaxy, with Z/Z
⊙ = 0.016, ever reported.
