Rencana Strategi Manajemen Pendidikan Islam

Published: November 2022

Globalisasi telah nyata melanda kehidupan, Suka atau pun tidak suka, ummat Islam harus menghadapinya dengan segala implikasinya. Ciri-ciri kehidupan global antara lain: Pertama, terjadinya pergeseran dari konflik ideologi dan politik ke arah persaingan perdagangan, investasi dan informasi; dari keseimbangan kekuatan (balance of power) ke arah keseimbangan kepentingan (balance of interest). Kedua, hubungan antar negara/bangsa secara struktural berubah dari sifat ketergantungan (dependency) ke arah saling ketergantungan (interdependency), hubungan yang bersifat primordial berubah menjadi sifat tergantung kepada posisi tawar-menawar (bargaining position). Ketiga, batas-batas geografis hampir kehilangan arti operasionalnya. Kekuatan suatu negara ditentukan oleh kemampuannya memanfaatkan keunggulan komparatif (comparative advantage) dan keunggulan kompetitif (competitive advantage). Keempat, persaingan antar negara sangat diwarnai oleh perang penguasaan teknologi tinggi. Setiap negara terpaksa menyediakan dana yang besar bagi penelitian dan pengembangan. Kelima, terciptanya budaya dunia yang cenderung mekanistik, efisien, tidak menghargai nilai dan norma yang secara ekonomi tidak efisien.Pergaulan global dengan cirinya seperti diuraikan di atas, disamping mendatangkan sejumlah kemudahan bagi manusia, juga mendatangkan sejumlah efek negatif yang dapat merugikan dan mengancam kehidupan.
Kenyataannya, pendidikan islam (khususnya di Indonesia) telah berjalan dalam lorong krisis yang panjang. Pendidikan Islam telah kehilangan pijakan filosofisnya yang hakiki, yang kemudian berdampak kepada tidak jelasnya arah dan tujuan yang hendak dicapai. Pendidikan Islam juga tertatih-tatih dan gagap dalam menghadapi laju perkembangan zaman dan arus globalisasi. Akibatnya, output pendidikan Islam, yang semestinya melahirkan generasi “imamul muttaqien” malah melahirkan generasi yang gagap: gagap teknologi, gagap pergaulan global, gagap zaman dan bahkan gagap moral.

Published: November 2022

The variety of communication services and the growing number of different sensors with the appearance of IoT (Internet of Things) technology generate significantly different types of network traffic. This implies that the structure of network traffic will be heterogeneous, which requires deep analysis to find the internal features underlying the data. A common model for analyzing the processes of a multiservice network is a model based on time series.
Numerous empirical data studies indicate that the packet intensity time series do not belong to the general aggregates of a normal distribution.
The problem of predicting network traffic is still relevant due to managing information that flows into a heterogeneous network.
In this work, the authors studied the time series for stationarity in order to select an appropriate forecasting model. A visual assessment of the series assumed non-stationarity. The Augmented Dickey-Fuller Test is applied, and the measured network traffic is predicted using the ARIMA (Auto-Regressive Integrated Moving Average) statistical method. Results were obtained using the Econometric Modeler Matlab (R2021b) application. The results of the autocorrelation function (ACF) and partial ACF are analyzed, with the help of which the ARIMA model is optimized. As a result of the study, a software algorithm for the ARIMA (0,2,1) model was developed.

Published: November 2022

Digitalization of the economy is one of the priority tasks set in the development strategies of Kazakhstan. Currently, there is a rapid change in information and communication technologies (ICT). Emerging changes affect network technologies, computing and communication devices themselves, as well as data processing. As a result, information technologies are being used in an increasing number of spheres of human life and economic life. One of the relevant areas of scientific research is the sphere of the living environment, which is currently developing from the field of Smart Homes into the field of Smart City, Smart Transport system, etc.
Today, cities have become the main force of economic development and have taken a central place in production, consumption networks, the definition of social and economic relations and currently provide a significant share of the gross domestic product of many countries. Cities began to play a major role in national, regional, and global development. The quality of people's lives depends on them. Therefore, today, more than ever, special requirements are imposed on them, such as the availability of affordable urban infrastructure, high mobility, security of urban areas, environmental friendliness, and developed urban self-government. Governments and city government bodies are facing new challenges that should not only solve a whole range of emerging problems, but also carry out a radical transformation of cities. One of the key components of the transformation is intelligent electrical networks.
This article aims to identify and systematize technological, economic and other effects of the introduction of intelligent networks. The article analyzes current trends and approaches to urban planning with an emphasis on energy infrastructure. A comprehensive approach to the development of the power supply system is noted, the main directions of its intellectualization are highlighted. The general requirements for the "smart" power supply system of Astana are defined, a conceptual management model of the "smart" power system is developed, and the effects of its implementation are described.
Constructing the Milky Way Stellar Halo in the Galactic Center by Direct Orbit Integration

Published: November 2022

Abstract
The halo stars on highly-radial orbits should inevitably pass the center regions of the Milky Way. Under the assumption that the stellar halo is in “dynamical equilibrium” and is axisymmetric, we integrate the orbits of ∼10,000 halo K giants at 5 ≤ r ≤ 50 kpc cross-matched from LAMOST DR5 and Gaia DR3. By carefully considering the selection function, we construct the stellar halo distribution at the entire regions of r ≤ 50 kpc. We find that a double-broken power-law function well describes the stellar halo’s density distribution with shallower slopes in the inner regions and the two breaks at r = 10 kpc and r = 25 kpc, respectively. The stellar halo becomes flatter from outer to inner regions but has q ∼ 0.5 at r ≲ 5 kpc. The stellar halo becomes isotropic with a slight prograde rotation in the inner 5 kpc, and reaches velocity dispersions of ∼250 km s−1. We get a weak negative metallicity gradient of −0.005 dex kpc−1 at 5 ≤ r ≤ 50 kpc, while there is an excess of relative metal-rich stars with [Fe/H] > −1 in the inner 10 kpc. The halo interlopers at r ≤ 5 kpc from integration of our sample has a mass of ∼1.2 × 108

Abstract
We present the first direct spectroscopic measurement of the stellar velocity dispersion function (VDF) for massive quiescent and star-forming galaxies at 0.6 < z ≤ 1.0. For this analysis we use individual measurements of stellar velocity dispersion from high-signal-to-noise-ratio spectra from the public Large Early Galaxy Astrophysics Census (LEGA-C) survey. We report a remarkable stability of the VDF for both quiescent and star-forming galaxies within this redshift range, though we note the presence of weak evolution in the number densities of star-forming galaxies. We compare both VDFs with previous direct and inferred measurements at local and intermediate redshifts, with the caveat that previous measurements of the VDF for star-forming galaxies are poorly constrained at all epochs. We emphasize that this work is the first to directly push to low stellar velocity dispersion (σ
⋆ > 100 km s−1) and extend to star-forming galaxies. We are largely consistent with the high-sigma tail measured from BOSS, and we find that the VDF remains constant from the median redshift of LEGA-C, z ∼ 0.8, to the present day.
An Improved Calibration of the Wavelength Dependence of Metallicity on the Cepheid Leavitt Law
Authors: Breuval Louise , Riess Adam G. , Kervella Pierre , Anderson Richard I. , Romaniello Martino 
Published: November 2022

Abstract
The Cepheid period–luminosity (PL) relation (or Leavitt law) has served as the first rung of the most widely used extragalactic distance ladder and is central to the determination of the local value of the Hubble constant (H
0). We investigate the influence of metallicity on Cepheid brightness, a term that significantly improves the overall fit of the distance ladder, to better define its wavelength dependence. To this aim, we compare the PL relations obtained for three Cepheid samples having distinct chemical composition (in the Milky Way and Magellanic Clouds) and focusing on the use of improved and recent data while covering a metallicity range of about 1 dex. We estimate the metallicity effect (hereafter γ) in 15 filters from mid-IR to optical wavelengths, including five Wesenheit indices, and we derive a significant metallicity term in all filters, in agreement with recent empirical studies and models, in the sense of metal-rich Cepheids being brighter than metal-poor ones. We describe the contribution of various systematic effects in the determination of the γ term. We find no evidence of γ changing over the wavelength range 0.5–4.5 μm, indicating that the main influence of metallicity on Cepheids is in their luminosity rather than color. Finally, we identify factors that sharpen the empirical constraints on the metallicity term over past studies, including corrections for the depth of the Magellanic Clouds, better-calibrated Cepheid photometry, improved Milky Way extinction estimates, and revised and expanded metallicity measurements in the LMC.

Published: November 2022

Abstract
We present the result of a broadband (0.5–70 keV) X-ray spectral analysis of the late-merger galaxy Mrk 739, which contains a dual active galactic nucleus (AGN), Mrk 739E and Mrk 739W, with a separation of ≈3.4 kpc. The spectra obtained with NuSTAR, Chandra, XMM-Newton, and Swift/BAT are simultaneously analyzed by separating the contributions from the two AGNs and extended emission with the Chandra data. To evaluate the reflection components from the AGN tori, we consider two models, a phenomenological one (pexrav and zgauss) and a more physically motivated one (XCLUMPY). On the basis of the results with XCLUMPY, we find that the AGNs in Mrk 739E and Mrk 739W have intrinsic 2–10 keV luminosities of 1.0 × 1043 and 7.5 × 1041 erg s−1 absorbed by hydrogen column densities of N

X-Ray Spectra from Weakly Magnetized Accretion Flows
Authors: Wallace John , Pe’er Asaf 
Published: November 2022

Abstract
In this paper, we expand upon previous work that argued for the possibility of a subequipartition magnetic field in the accretion flow of a black hole binary system. Using X-ray observations of the three well-known sources A0620-00, XTE J1118+480, and V404 Cyg during the quiescent state, we compare the theoretically expected spectral shape with the observed data in order to verify that the parameters of the subequipartition model are plausible. In all three cases, we find that it is possible to reproduce the spectral shape of the X-ray observations with a subequipartition flow. These findings support the idea that the quiescent state spectrum of X-ray binary systems is produced by a weakly magnetized accretion flow. A subequipartition flow would pose a significant challenge to our current understanding of jet launching, which relies on the presence of a strong magnetic field to power the jet.

Abstract
Dipper stars are a classification of young stellar objects that exhibit dimming variability in their light curves, dropping in brightness by 10%–50%, likely induced by occultations due to circumstellar disk material. This variability can be periodic, quasiperiodic, or aperiodic. Dipper stars have been discovered in young stellar associations via ground-based and space-based photometric surveys. We present the detection and characterization of the largest collection of dipper stars to date: 293 dipper stars, including 234 new dipper candidates. We have produced a catalog of these targets, which also includes young stellar variables that exhibit predominately burst-like variability and symmetric variability (equal parts bursting and dipping). The total number of catalog sources is 414. These variable sources were found in a visual survey of TESS light curves, where dip-like variability was observed. We found a typical age among our dipper sources of <5 Myr, with the age distribution peaking at ≈2 Myr, and a tail of the distribution extending to ages older than 20 Myr. Regardless of the age, our dipper candidates tend to exhibit infrared excess, which is indicative of the presence of disks. TESS is now observing the ecliptic plane, which is rich in young stellar associations, so we anticipate many more discoveries in the TESS data set. A larger sample of dipper stars would enhance the census statistics of light-curve morphologies and dipper ages.
New Methanol Maser Transitions and Maser Variability Identified from an Accretion Burst Source G358.93-0.03

Published: November 2022

Abstract
The high-mass young stellar object G358.93-0.03 underwent an accretion burst during the period from 2019 January to June. Given its extraordinary conditions, a number of new maser transitions may have been naturally excited during the burst stage. Searching for new maser lines and monitoring maser variability associated with the accretion burst event are important for understanding the complex conditions of the massive star formation toward G358.93-0.03. In this work, using the Shanghai 65 m Tianma Radio Telescope, we continuously monitored the multiple maser (including methanol and water) transitions toward G358.93-0.03 during the burst in the period from 2019 March 14 to May 20. There were 23 CH3OH maser transitions and one H2O maser transition detected from the monitoring. Nearly all the detected maser transitions toward this source have dramatic variations in their intensities within a short period of ∼2 months. Eight new methanol transitions from G358.93-0.03 were identified to be masering in our observations based on their spectral profile, line width, intensity, and the rotation diagram. During the monitoring, the gas temperature of the clouds in the case of saturated masers can show a significant decline, indicating that the maser clouds were going through a cooling process, possibly associated with the propagation of a heat wave induced by the accretion burst. Some of the maser transitions were even detected with the second flares in 2019 April, which may be associated with the process of the heat-wave propagation induced by the same accretion burst acting on different maser positions.
Optimal Defocus for Phase Diversity Wave Front Retrieval
Authors: Bailén F. J. , Orozco Suárez D. , Blanco Rodríguez J. , del Toro Iniesta J. C. 
Published: November 2022

Abstract
Phase diversity techniques are widely employed in solar astronomy to evaluate and correct the aberrations stemming from atmospheric turbulences, the telescope, and its instruments. The method uses information provided by a pair of images. One of them is usually focused while the other one is defocused. The amount of defocus to be induced is somehow arbitrary, though. In this work we carry out a series of numerical experiments with artificial solar images to investigate the performance of phase diversity for different choices of the relative defocus among the two images. The experiments allow us to determine the amount of defocus that produces the best wave front restoration when changing: (1) the number of Zernike polynomials of the retrieved and/or incident wave fronts; (2) the signal-to-noise ratio of the images; (3) the amplitude of the incident aberrations; and (4) the observed scene. We find a correlation between the amount of defocus needed for optimal restorations and the number of Zernike polynomials employed in the optimization. Values larger than the typically accepted choice of 1λ (peak to peak) are obtained in most cases.
Performance of Sequential Phase Diversity with Dynamical Solar Scenes
Authors: Bailén F. J. , Orozco Suárez D. , Blanco Rodríguez J. , del Toro Iniesta J. C. 
Published: November 2022

Abstract
Phase diversity techniques are usually based on the comparison of synchronously acquired pairs of focused–defocused images. This way, differences between both images are avoided except from random pixel variations due to noise on the detector and the phase diversity itself. In some astronomical instruments, though, the two images are not taken simultaneously. This work studies the impact of carrying out phase diversity with pairs of asynchronously acquired images while observing an evolving solar scene. We evaluate the performance of this technique as a function of the time gap between the images through the use of a magnetohydrodynamical simulation of the solar scene as observed by an instrument. We describe the incident wave front with two numbers of Zernike polynomials (20 or 32) to explore their effect on the wave front sensing accuracy and we employ two levels of noise to study their impact in the object restoration. We find that a time gap among our simulation images smaller than ∼10 s has a negligible impact on the performance of the method. The rms error of the Zernike coefficients fitting worsens exponentially from there on, but the evolution is similar no matter the number of polynomials used in the fitting. Meanwhile, the quality of the object restoration benefits from lower noise levels, but it decreases linearly with the time gap independently of the amount of noise.
