Daging sapi merupakan salah satu sumber protein hewani yang masih menjadi pilihan utama dalam memenuhi kebutuhan protein sebagian masyarakat Indonesia. Permasalahan pemetaan jaringan logistic menjadi persoalan utama dalam mereduksi harga jual dan pemenuhan kebutuhan daging sapi di Kotamadya Bandung. Ada tiga aliran utama dalam saluran distribusi daging sapi yaitu aliran material, informasi dan finansial, dimana ketiga aliran tersebut saling berhubungan dan mempengaruhi. Aliran material mengalir dari hulu ke hilir yaitu dari jagal hingga konsumen daging sapi. Aliran keuangan mengalir dari hilir ke hulu yaitu dari konsumen akhir daging sapi ke jagal. Aliran informasi mengalir pada mata rantai secara timbal balik. Aliran material dibagi menjadi dua jenis yaitu daging sapi import dan lokal. Aliran distribusi daging sapi lokal mengalir dari feedloter, peternak lokal, rumah potong hewan, jagal pedagang besar daging sapi, pedagang pengecer sampai konsumen akhir yaitu Horeca, industry olahan dan konsumen rumah tangga. Komponen-komponen yang terlibat dalam jaringan logistik daging sapi import adalah perusahaan-perusahaan importir daging sapi yang didatangkan dari Australia, New Zeland, Brazil, Spanyol dan India yang berbetuk frozen meat. Aliran finansial berisikan harga-harga dari bandar sampai dijual ke konsumen akhir juga proses pembayaran. Sedangkan aliran informasi berisikan pemasok daging sapi, lokasi pembelian, kualitas daging sapi dan jumlah persediaan daging sapi di Kota Bandung. Metode survey digunakan dalam penelitian ini sehingga pemetaan jalur logistik daging sapi dapat dilakukan dengan lebih detail dan jelas. Penenlitian pemetaan jalur logistik daging sapi di kota Bandung menghasilkan alur yang jelas mengenai distribusi daging sapi baik lokal maupun impor yang tentunya sangat berguna bagi para pihak yang terlibat dalam saluran distribusi daging sapi di kota Bandung.

This study aims to determine the effectiveness of countermeasures against copyright piracy from a legal system perspective. The research method used is a normative juridical approach, starting from secondary data consisting of primary legal materials, secondary legal materials, and tertiary legal materials. The data collection technique was carried out through document study and qualitative normative data analysis.
The legal structure is related to Law no. 28/2014 concerning Copyright still has obstacles related to the consistency of law enforcers (especially investigators, especially Civil Servant Investigators) who have carried out their functions but have not been effective due to internal and external constraints. In terms of legal substance, the Copyright Law has a normative weakness, namely adhering to a complaint offense against copyright crimes which causes law enforcement to take longer. Meanwhile, in terms of legal culture, the public has not fully respected the creations of other parties, as evidenced by the increasing number of piracy of copyright works and a way of thinking that considers intellectual property including copyright to only have a social function, even though it is also an individual right that has economic value. Therefore, the application of the legal system according to Friedman on the effectiveness of counter piracy of copyright works has not been effective.

Abstract
We report on a highly efficient polariton emission of poly [2-methoxy-5-(3, 7-dimethyloctyloxy)-1, 4-phenylenevinylene] (MDMO-PPV) organic light-emitting diode (OLED) operating in the ultrastrong coupling regime. MDMO-PPV film with a broadband high absorbance and modest Stokes shift is shown to enable the generation of a large coupling strength and radiative pumping of the lower polariton (LP) mode. Further combining the optimized conditions of cavity design, electron injection, and emission side mirror, we demonstrate that the polariton OLED can produce a spectrally narrow and almost angle-independent emission from the LP mode, with a maximum external quantum efficiency of >0.1% and a Rabi splitting energy of >0.8 eV.

Abstract
In recent years, studies on porous nanostructures have shown the topological structure of porous material has an important effect on heat flow control. However, for porous structures, the complexity of geometry brings great difficulties to the study of phonon transport behaviors. Especially, phonon mean free path (MFP) can no longer be calculated just by approximate structural simplifications. In this work, we applied the Monte Carlo method to estimate phonon geometric MFP of three-dimensional nanostructures and analyzed phonon transport behaviors in the nanostructures. A specific compound structure composed of a cubic porous base and a phonon waveguide was proposed to improve thermal management, the dependencies of thermal conductivities on different porosities, pore radiuses and inclination angles were studied. The results show thermal fluxes can be tuned not only by changing porosities or pore radiuses but also by modulating the inclination angles of the compound structures.

Currently, as a result of a noticeable increase in transport loads on bridge structures, the task of investigating the ability of the structure to work in extreme operating conditions becomes urgent. A more accurate assessment of the bearing capacity of reinforced concrete bridge structures can be obtained by taking into account the actual diagram of the material. This work is devoted to the development of an effective method for calculating the reinforced concrete frame support of a bridge structure in the conditions of inelastic deformation of steel and concrete. The use of the LIRA software and computing complex makes it possible to make the calculation technologically advanced and convenient for use in everyday engineering practice. The problem of determining the bearing capacity of the rack-and-crossbar support of the overpass for the combined action of permanent and temporary mobile loads based on the principle of ultimate equilibrium is solved. The upper estimate of the maximum possible time load arising in exceptional operating conditions is given.

Abstract
Flat-spectrum radio quasars (FSRQs) are the most luminous blazars at GeV energies but only rarely emit detectable fluxes of TeV gamma rays, typically during bright GeV flares. We explore the gamma-ray variability and spectral characteristics of three FSRQs that have been observed at GeV and TeV energies by Fermi-LAT and VERITAS, making use of almost 100 hr of VERITAS observations spread over 10 yr: 3C 279, PKS 1222+216, and Ton 599. We explain the GeV flux distributions of the sources in terms of a model derived from a stochastic differential equation describing fluctuations in the magnetic field in the accretion disk and estimate the timescales of magnetic flux accumulation and stochastic instabilities in their accretion disks. We identify distinct flares using a procedure based on Bayesian blocks and analyze their daily and subdaily variability and gamma-ray energy spectra. Using observations from VERITAS, as well as Fermi, Swift, and the Steward Observatory, we model the broadband spectral energy distributions of PKS 1222+216 and Ton 599 during very high energy (VHE)–detected flares in 2014 and 2017, respectively, strongly constraining the jet Doppler factors and gamma-ray emission region locations during these events. Finally, we place theoretical constraints on the potential production of PeV-scale neutrinos during these VHE flares.
Interstellar Planetesimals: Potential Seeds for Planet Formation?
Authors: Moro-Martín Amaya , Norman Colin 
Published: January 2022

Abstract
We investigate the trapping of interstellar objects during the early stages of star and planet formation. Our results show a very wide range of possible values that will be narrowed down as the population of interstellar objects becomes better characterized. When assuming a background number density of 2 · 1015 pc−3 (based on 1I’s detection), a velocity dispersion of 30 km s−1, and an equilibrium size distribution, the number of interstellar objects captured by a molecular cloud and expected to be incorporated to each protoplanetary disk during its formation is O(109) (50 cm–5 m), O(105) (5–50 m), O(102) (50–500 m), O(10−2) (500 m–5 km). After the disk has formed, the number of interstellar objects it can capture from the ISM during its lifetime is 6 · 1011 (50 cm–5 m), 2 · 108 (5–50 m), 6 · 104 (50–500 m), 20 (500 m–5 km); in an open cluster where 1% of stars have undergone planet formation, these values increase by a factor of O(102–103). These trapped interstellar objects might be large enough to rapidly grow into larger planetesimals via the direct accretion of the subcm-sized dust grains in the protoplanetary disk before they drift in due to gas drag, helping overcome the meter-size barrier, acting as “seeds” for planet formation. They should be considered in future star and planet formation models, as well as in the potential spread of biological material across the Galaxy.
A Study of Sunspot 3 Minute Oscillations Using ALMA and GST

Published: January 2022

Abstract
Waves and oscillations are important solar phenomena, not only because they can propagate and dissipate energy in the chromosphere, but also because they carry information about the structure of the atmosphere in which they propagate. The nature of the 3 minute oscillations observed in the umbral region of sunspots is considered to be an effect of propagation of magnetohydrodynamic waves upward from below the photosphere. We present a study of sunspot oscillations and wave propagation in NOAA Active Region 12470 using an approximately 1 hr long data set acquired on 2015 December 17 by the Atacama Large Millimeter/submillimeter Array (ALMA), the Goode Solar Telescope (GST) operating at the Big Bear Solar Observatory, the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory, and the Interface Region Imaging Spectrograph. The ALMA data are unique in providing a time series of direct temperature measurements in the sunspot chromosphere. The 2 s cadence of ALMA images allows us to well resolve the 3 minute periods typical of sunspot oscillations in the chromosphere. Fourier analysis is applied to ALMA Band 3 (∼100 GHz, ∼3 mm) and GST Hα data sets to obtain power spectra as well as oscillation phase information. We analyzed properties of the wave propagation by combining multiple wavelengths that probe physical parameters of solar atmosphere at different heights. We find that the ALMA temperature fluctuations are consistent with that expected for a propagating acoustic wave, with a slight asymmetry indicating nonlinear steepening.
An Efficient Signal-to-noise Approximation for Eccentric Inspiraling Binaries
Authors: Randall Lisa , Shelest Alexandra , Xianyu Zhong-Zhi 
Published: January 2022

Abstract
Eccentricity has emerged as a potentially useful tool for helping to identify the origin of black hole mergers. However, eccentric templates can be computationally very expensive owing to the large number of harmonics, making statistical analyses to distinguish formation channels very challenging. We outline a method for estimating the signal-to-noise ratio (S/N) for inspiraling binaries at lower frequencies such as those proposed for LISA and DECIGO. Our approximation can be useful more generally for any quasi-periodic sources. We argue that surprisingly, the S/N evaluated at or near the peak frequency (of the power) is well approximated by using a constant-noise curve, even if in reality the noise strain has power-law dependence. We furthermore improve this initial estimate over our previous calculation to allow for frequency dependence in the noise to expand the range of eccentricity and frequency over which our approximation applies. We show how to apply this method to get an answer accurate to within a factor of 2 over almost the entire projected observable frequency range. We emphasize this method is not a replacement for detailed signal processing. The utility lies chiefly in identifying theoretically useful discriminators among different populations and providing fairly accurate estimates for how well they should work. This approximation can furthermore be useful for narrowing down parameter ranges in a computationally economical way when events are observed. We furthermore show a distinctive way to identify events with extremely high eccentricity where the signal is enhanced relative to naive expectations on the high-frequency end.
The Solar Eruption of 2017 September 10: Wavy with a Chance of Protons

Published: January 2022

Abstract
High-resolution SUVI images reveal an interesting new picture of particle acceleration in powerful solar eruptions. Typically, powerful solar eruptions include a coronal wave component, as well the traditional CME and flare components. At low solar altitudes, coronal waves refract downward, toward the solar surface, because of the slower Alfvén speeds at the base of the corona. The refracted wave plus the shock wave ahead of an intense CME allow for a two-step shock acceleration process that can result in relativistic or GLE particles. This mechanism may be particularly applicable to the first-to-arrive, prompt relativistic particles measured by the Fort Smith neutron monitor during GLE # 72 on 2017 September 10.

Abstract
There is a growing concern about an impact of low-Earth-orbit (LEO) satellite constellations on ground-based astronomical observations, in particular, on wide-field surveys in the optical and infrared. The Zwicky Transient Facility (ZTF), thanks to the large field of view of its camera, provides an ideal setup to study the effects of LEO megaconstellations—such as SpaceX’s Starlink—on astronomical surveys. Here, we analyze the archival ZTF observations collected between 2019 November and 2021 September and find 5301 satellite streaks that can be attributed to Starlink satellites. We find that the number of affected images is increasing with time as SpaceX deploys more satellites. Twilight observations are particularly affected—a fraction of streaked images taken during twilight has increased from less than 0.5% in late 2019 to 18% in 2021 August. We estimate that once the size of the Starlink constellation reaches 10,000, essentially all ZTF images taken during twilight may be affected. However, despite the increase in satellite streaks observed during the analyzed period, the current science operations of ZTF are not yet strongly affected. We also find that redesigning Starlink satellites (by installing visors intended to block sunlight from reaching the satellite antennas to prevent reflection) reduces their brightness by a factor of 4.6 ± 0.1 with respect to the original design in g, r, and i bands.
