URGENSI PENDIDIKAN ISLAM DALAM KELUARGA
Authors: Nurhanifah Nurhanifah 
Published: April 2019

Tulisan ini menjelaskan tentang makna pendidikan Islam yang harus diajarkan dalam keluarga, urgensinya dan aspek-aspek pendidikan Islam apa saja yang seharusnya diajarkan kepada anak-anak. Dalam hal ini yang bertanggung jawab akan hal tersebut adalah orang tua, karena anak adalah amanah yang harus dijaga, dididik dan dibimbing agar dia bisa menjalani kehidupan yang sesuai dengan ajaran Islam dan bisa memperoleh kebahagian di akhirat nantinya. Setidaknya ada tiga aspek penting yang seharusnya ditanamkan orang tua sejak dini bagi anak-anaknya, yaitu aspek aqidah, ibadah dan akhlak. Aspek aqidah berkaitan dengan keimanan kepada Allah dan Rasul-Nya, penerapannya yaitu dengan cara mengajarkan keyakinan yang benar tentang adanya Allah sebagai pencipta. Aspek ibadah, berkaitan dengan ketundukan makhluk untuk menyembah Allah yang maha Esa, ini bisa diterapkan dengan membiasakan anak melakukan sholat lima waktu, mengajarkan anak baca al-Qur’an, memberi shadaqah dan lain-lain. Kemudian Aspek akhlak berkaitan dengan adab, sopan santun dan berprilaku baik. Penerapannya melalui keteladanan orang tua baik ketika berbicara, melakukan sesuatu dan lain-lain, dan juga bisa diterapkan dengan melalui pembiasaan, misalnya membiasakan masuk rumah dengan mengucapkan salam, makan dengan tangan kanan dan tidak sambil berdiri dan lain sebagainya.

Developments and Theoretical Approaches on Public Diplomacy
Authors: Brovina Ngadhnjim 
Published: April 2019

Seems that had never been agreed upon definition of the term: public diplomacy. This lack of consensus about the definition may prove to be a good thing because, it encourages researchers to explore this area further, and remains to be seen in the future that maybe we will have an accurate and precise term about public diplomacy.
Public diplomacy is seen as an evolving field, a multi-disciplinary field with its theoretical, conceptual and methodological links in some of disciplines such as international relations, media studies, public relations, etc..
When we talk about functions, history and trends of development of public diplomacy, normally is more easily, because we can find more literature, although most of it is in English and just a few in the Albanian language.
The general approach of my research has to do with recognition of some of the theoretical aspects and some of the practices of influence and domination of public diplomacy, concretized with concrete examples.
New Near-infrared Imaging and Spectroscopy of NGC 2071-IR
Authors: Walther D. M. , Geballe T. R. 
Published: April 2019

Abstract
We present high-resolution images of NGC 2071-IR in the J, H, and K bands and in the emission at 2.12 μm of the v = 1–0 S(1) line of molecular hydrogen. We also present moderate-resolution K-band spectra of two young stellar objects, IRS 1 and IRS 3, within NGC 2071-IR, that are candidate sources of one or more of the outflows observed in the region. Two of the eight originally identified infrared point sources in NGC 2071-IR are binaries, and we identify two new sources, one coincident with the radio source Very Large Array-1 and highly reddened. The H2 Q(3)/S(1) line intensity ratios at IRS 1 and IRS 3 yield high and very high extinctions, respectively, to them, as is implied by their near-infrared colors and K-band continuum slopes. The spectra also reveal the presence of hot, dense circumstellar molecular gas in each, suggesting that both are strong candidates for having energetic molecular outflows. We agree with a previous suggestion that IRS 1 is the likely source of an east–west-oriented outflow and conclude that this outflow is probably largely out of the plane of the sky. We also conclude that if IRS 3 is the source of the large-scale northeast–southwest outflow, as has been previously suggested, its jet/wind must precess in order to explain the angular width of that outflow. We discuss the nature of the point sources and their possible contributions, if any, to the complex morphology of the H2 line emission.

Abstract
We present results of a 7–12 GHz phased-array study of the Galactic center magnetar J1745−2900 with the Karl G. Jansky Very Large Array (VLA). Using data from two 6.5 hr observations from 2014 September, we find that the average profile is comprised of several distinct components at these epochs and is stable over ∼day timescales and ∼GHz frequencies. Comparison with additional phased VLA data at 8.7 GHz shows significant profile changes on longer timescales. The average profile at 7–12 GHz is dominated by the jitter of relatively narrow pulses. The pulses in each of the four main profile components seen in 2014 September are uncorrelated in phase and amplitude, though there is a small but significant correlation in the occurrence of pulses in two of the profile components. Using the brightest pulses, we measure the dispersion and scattering parameters of J1745−2900. A joint fit of 38 pulses gives a 10 GHz pulse-broadening time of

and a dispersion measure of

. Both of these results are consistent with previous measurements, which suggests that the scattering and dispersion measure of J1745−2900 may be stable on timescales of several years.
Synthetic Spectra of Pair-instability Supernovae in 3D

Published: April 2019

Abstract
Pair-instability supernovae (PISNe) may signal the deaths of extremely massive stars in the local Universe or massive primordial stars after the end of the Cosmic Dark Ages. Hydrodynamic simulations of these explosions, performed in 1D, 2D, and 3D geometry, have revealed the strong dependence of mixing in the PISN ejecta on dimensionality. This chemical rearrangement is mainly driven by Rayleigh–Taylor instabilities that start to grow shortly after the collapse of the carbon–oxygen core. We investigate the effects of such mixing on the spectroscopic evolution of PISNe by post-processing explosion profiles with the radiation diffusion-equilibrium code SNEC and the implicit Monte Carlo–discrete diffusion Monte Carlo radiation transport code SuperNu. The first 3D radiation transport calculation of a PISN explosion is presented, yielding viewing-angle-dependent synthetic spectra and light curves. We find that while 2D and 3D mixing does not significantly affect the light curves of PISNe, their spectroscopic and color evolution are impacted. Strong features of intermediate-mass elements dominated by silicon, magnesium, and oxygen appear at different phases and reach different intensities depending on the extent of mixing in the silicon/oxygen interface of the PISN ejecta. On the other hand, we do not find a significant dependence of PISN light curves and spectra on viewing angle. Our results showcase the capabilities of SuperNu to handle 3D radiation transport and highlight the importance of modeling time series of spectra in identifying PISNe with future missions.

Abstract
We present extensive optical photometric and spectroscopic observations, from 4 to 482 days after explosion, of the Type II-plateau (II-P) supernova (SN) 2017eaw in NGC 6946. SN 2017eaw is a normal SN II-P intermediate in properties between, for example, SN 1999em and SN 2012aw and the more luminous SN 2004et, also in NGC 6946. We have determined that the extinction to SN 2017eaw is primarily due to the Galactic foreground and that the SN site metallicity is likely subsolar. We have also independently confirmed a tip-of-the-red-giant-branch (TRGB) distance to NGC 6946 of 7.73 ± 0.78 Mpc. The distances to the SN that we have also estimated via both the standardized candle method and expanding photosphere method corroborate the TRGB distance. We confirm the SN progenitor identity in pre-explosion archival Hubble Space Telescope (HST) and Spitzer Space Telescope images, via imaging of the SN through our HST Target of Opportunity program. Detailed modeling of the progenitor’s spectral energy distribution indicates that the star was a dusty, luminous red supergiant consistent with an initial mass of ∼15 M
⊙.

Abstract
The Seyfert galaxy Mrk 335 is known for its frequent changes of flux and spectral shape in the X-ray band that occurred during recent years. These variations may be explained by the onset of a wind that previous, noncontemporaneous high-resolution spectroscopy in X-ray and UV bands located at accretion disk scale. A simultaneous new campaign by XMM-Newton and the Hubble Space Telescope (HST) caught the source at a historically low flux in the X-ray band. The soft X-ray spectrum is dominated by prominent emission features and by the effect of a strong ionized absorber with an outflow velocity of (5–6) × 103 km s−1. The broadband spectrum obtained by the EPIC-pn camera reveals the presence of an additional layer of absorption by gas at moderate ionization covering ∼80% of the central source, as well as tantalizing evidence for absorption in the Fe K band outflowing at the same velocity of the soft X-ray absorber. The HST Cosmic Origins Spectrograph spectra confirm the simultaneous presence of broad absorption troughs in C iv, Lyα, Lyβ, and O vi, with velocities of the order of 5000 km s−1 and covering factors in the range of 20%–30%. Comparison of the ionic column densities and of other outflow parameters in the two bands shows that the X-ray and UV absorbers are likely originated by the same gas. The resulting picture from this latest multiwavelength campaign confirms that Mrk 335 undergoes the effect of a patchy, medium-velocity outflowing gas in a wide range of ionization states that seem to be persistently obscuring the nuclear continuum.

Published: April 2019

Background In 2001, an international beverage company implemented an HIV workplace programme providing free antiretroviral treatment (ART) for employees and dependents in sub-Saharan Africa, at a time when ART, cost assessments of ART programmes and related public funding was hardly available. This study describes the outcomes of this programme with respect to achieving the UNAIDS 90-90-90 targets in five African countries and analyses trends over the past 15 years. Methods Anonymous human resource data were analysed in three cohorts of participants (those enrolling in 2001– 2005, 2006–2010 and 2011–2015). Results Over 15 years, 42,490 unique individuals in five African countries were tested for HIV in this programme and 746 (1.8%) were found to be HIV-infected. Between 2002 and 2015, the proportion of HIV-positive participants on ART increased from 42% to 94% and the proportion of participants on ART who achieved virological suppression increased from 38% to 87%. Conclusions This study shows that in one of the earliest HIV treatment programmes in Africa long-term success has been achieved, approaching the current UNAIDS 90-90-90 targets, demonstrating that the treatment of HIV in developing countries is possible with superior results at low costs (45 US dollars/employee). Reasons for this success include continuous access to on-site quality care and ART and the assistance of an independent NGO with experience in HIV treatment. This provides an argument to continue private sector involvement in international efforts to combat HIV/AIDS, particularly in light of increased ART targets, under-capacity in the public sector and stagnating international funding.

Published: April 2019

Abstract
This paper describes the overall project execution of the Aasta Hansteen field development.
The Aasta Hansteen Field development in 1300m water depth is the deepest field developed on the Norwegian Continental Shelf (NCS). The field is located north of the Arctic circle, in harsh environment, 300km off the coast of Northern Norway, with no other offshore installations in the area.
The Aasta Hansteen field is developed with a floating Spar FPSO, using steel catenary risers and polyester mooring lines. The Aasta Hansteen platform will serve as a hub for future discoveries and field developments in the area.
The rich gas is exported through a 482km long 36" pipeline (Polarled) to an onshore processing plant at Nyhamna for further processing to sales gas. From there the gas is exported to the European market. Stabilized condensate is stored in the Spar FPSO and offloaded to shuttle tankers.
Turret-Moored FPSO Yaw Motions in a Squall-Prone Region
Authors: Naciri Mamoun , Chitrapu Murthy 
Published: April 2019

The design of mooring systems in West of Africa is often dominated by squall events. These are episodes of rapidly increasing wind speeds accompanied with sudden and significant wind direction changes. The response of weathervaning systems (offloading tankers moored to an export system or turret moored FPSO’s) to such transient and violent environments is very complex and the subject of an on-going joint industry project. One important parameter in numerical simulations of weathervaning units to squall events is the yaw motion damping model. There is quite a large body of references and insights in yaw damping under steady environmental conditions but hardly any when it comes to responses in squall owing to the transient nature of the event and to its complexity.
Field measurements of the yaw motions of a turret moored unit offshore Angola with concurrent on-board wind measurements are presented. Both quantities are sampled at 1-minute intervals. Time series of aft and fore drafts are also available on a daily basis. These measurements span one decade. A systematic scan of the wind speed time series has been performed to identify, based on the World Meteorological Organization definition, all squall events passing through the asset. The main particulars of the turret-moored FPSO are described along with its station-keeping system and the associated horizontal slow drift motion response time scales.
Systematic analysis of measured yaw motions and velocities has been performed seeking correlations with the hull loading condition at the time of the squall event, its heading prior to the squall and the squall maximum speed and direction range. The main objective of these analyses is to provide factual information that can be used to firm up the yaw damping models used for mooring analyses in squall-prone areas.

Published: April 2019

Abstract
Oil and gas industry experiences indicate mooring chain corrosion is a major challenge. Observed corrosion rates in the field can be several times higher than the design allowance. In addition, pitting corrosion is not considered in design but can be significant in service. Pre-emptive chain replacements may be required which are typically very costly. In addition to corrosion, some of the other performance factors for mooring chains include strength, wear resistance, toughness and fatigue resistance. Carbon steel is the conventional material currently employed for mooring chains. There are significant incentives to develop new material technologies with improved seawater corrosion and wear performance for mooring chain application.
This paper describes one such new material technology – High Manganese Steel (HMS), and its assessment for mooring chain application. HMS is a family of alloyed steels that, when optimized, can offer improved properties over conventional carbon steel. Several HMS chemistries were manufactured, on which small scale performance evaluation testing and weldability assessments were carried out. Based on the assessments, these custom HMS alloys show promising results in terms of the performance factors required for mooring chain application.
Design Advancements for FLNG Coil Wound Heat Exchanger Technology
Authors: McConville John , Dally John 
Published: April 2019

Abstract
Floating LNG (FLNG) has led to more compact plant layouts, a move to more modular construction methods, and marinization of traditional land based equipment. These developments have led to advancements in coil wound heat exchanger (CWHE) designs. This includes designing for blast loading, accounting for the fatigue impact of wave induced accelerations, new materials and coating systems for a marine environment, and novel base designs to take advantage of the modular construction. This paper describes these changes and the innovations in design and fabrication that will meet these new requirements and challenges.
Smart Offshore Ecosystem – Enabling a Safe and Sustainable Offshore Environment Utilizing Smart Technology
Authors: Thigpen Joel 
Published: April 2019

Abstract
With continued pressure to reduce costs of offshore developments, coupled with more stringent environmental regulations and a continued focus on safe operations; operators, drilling contractors, and service companies alike, continue to explore different avenues to remove waste within their operations by removing inefficiencies in a safe and environmentally responsible way.
If we take a closer look at other industries, we can find technologies that exist today that can be adopted and adapted to support the offshore O&G industry in these efforts to remove waste. Hybrid power systems, remote operations, digitalization, big data analytics, and automation are just a few of the tools that can drive this sustainable environment. In this paper we will explore these technologies and how their adoption can positively impact the entire offshore environment. The intent is to elicit new thoughts, and ideas of how we can collaborate, as an industry, in creating a safe and sustainable Smart Offshore Ecosystem.
