Sustainable livestock agriculture from Islamic perspective
Authors: Fuseini Awal , Lever John 
Published: May 2021

AbstractWith the impact of climate change becoming increasingly apparent, there have been calls for world leaders to take measures aimed at mitigating the potential effect on the environment of the rapid expansion in human population, urbanisation, deforestation, agricultural development, industrialisation and the rampant burning of fossil fuels. This article reviews literature on the spiritual dimensions of environmental sustainability from an Islamic perspective, with emphasis on the sustainable utilisation of agricultural resources linked to production and consumption. The religious standpoints on stewardship of nature (Khilafa), climate change and animal welfare are explored from within the Islamic scriptures to gain a better understanding of sustainable development from an Islamic perspective, particularly with regard to meat production. The description of humans as stewards or guardians of nature in Islamic literature is a direct call from God for humanity to safeguard the natural capital in order to maintain synergistic relationship between flora, fauna and other biodiversity.

Abstract
Thermoelectric measurements have the potential to uncover the density of states (DOSs) of low-dimensional materials. Here, we present the anomalous thermoelectric behavior of monolayer graphene-nanowire (NW) heterostructures, showing large oscillations as a function of the doping concentration. Our devices consist of InAs NW and graphene vertical heterostructures, which are electrically isolated by thin (∼10 nm) hexagonal boron nitride (hBN) layers. In contrast to conventional thermoelectric measurements, where a heater is placed on one side of a sample, we use the InAs NW (diameter ∼50 nm) as a local heater placed in the middle of the graphene channel. We measure the thermoelectric voltage induced in graphene due to Joule heating in the NW as a function of temperature (1.5–50 K) and carrier concentration. The thermoelectric voltage in bilayer graphene (BLG)-NW heterostructures shows sign change around the Dirac point, as predicted by Mott’s formula. In contrast, the thermoelectric voltage measured across monolayer graphene (MLG)-NW heterostructures shows anomalous large-amplitude oscillations around the Dirac point, not seen in the Mott response derived from the electrical conductivity measured on the same device. The anomalous oscillations are a signature of the modified DOSs in MLG by the electrostatic potential of the NW, which is much weaker in the NW-BLG devices. Thermal calculations of the heterostructure stack show that the temperature gradient is dominant in the graphene region underneath the NW, and thus sensitive to the modified DOSs resulting in anomalous oscillations in the thermoelectric voltage. Furthermore, with the application of a magnetic field, we detect modifications in the DOSs due to the formation of Landau levels in both MLG and BLG.
Magnetohydrodynamic hybrid simulation model with kinetic thermal ions and energetic particles
Authors: Todo Y , Sato M , Wang Hao , Idouakass M , Seki R 
Published: May 2021

Abstract
A new kinetic-magnetohydrodynamic hybrid simulation model where the gyrokinetic particle-in-cell simulation is applied to both thermal ions and energetic particles is presented. Toroidal Alfvén eigenmodes (TAEs) destabilized by energetic ions in tokamak plasmas are simulated with the new simulation model. Energy channeling from energetic ions to thermal ions through Alfvén eigenmodes (AEs) is demonstrated by the simulation. The distribution function fluctuations and the resonance condition are analyzed for both thermal ions and energetic ions. The strong energy transfer between the particles and the AE and the strong particle transport occur when the following conditions are satisfied at the resonance location in phase space: (1) the poloidal resonance number is close to the poloidal mode number of the AE, (2) the AE has a substantial amplitude, (3) the distribution function has a substantial gradient along the

E

const.

line, where

E

′

is a conserved variable for the wave-particle interaction. While the distribution function fluctuations for energetic ions are consistent with the resonance condition with the TAEs, the distribution function fluctuations for thermal ions do not satisfy the resonance condition when the bulk plasma beta is 1%. This indicates that the resonance does not play an important role in the interaction between thermal ions and the TAE for the relatively low bulk plasma temperature. On the other hand, when the bulk plasma beta is 4%, the resonance between thermal ions and the TAEs become important leading to Landau damping.
Coherent cyclotron emission with a helical wavefront from multi-electron system accelerated by the circularly polarized wave
Authors: Goto Yuki , Kubo Shin , Tsujimura Toru Ii 
Published: May 2021

Abstract
In this study, we calculated coherent electron cyclotron emission (ECE) with helical wavefront from a multi-electron system which passes through a magnetic mirror field with cyclotron motion. ECE from a multi-electron system is usually incoherent radiation due to the random rotation phase of each electron, and it is difficult to observe the helical wavefront. However, when a resonant external electromagnetic field is applied, the gyro-phase of electrons are controlled, and coherent ECE is expected to be observed. These processes were numerically calculated under the given experimental condition and confirmed that the higher harmonics ECE has helical wavefront.
Slow light-based refractive index sensor in single mode photonic crystal waveguide
Authors: Samadian Barough Ali , Noori Mina , Abbasiyan Amin 
Published: May 2021

Abstract
Here, a slow light-based refractive index sensor has been presented in a hole-type 2D hexagonal lattice photonic crystal waveguide by insertion of only four defect holes inside the channel. The width of the channel has been optimized to provide single mode operation and large free spectral range. Also, the performance of the sensor with and without introducing the central cavity inside the channel have been regarded for different radii of defects. The proposed sensor presents the highest sensitivity and detection range of 126 nm/RIU and 1–2.2, respectively for the detection based on band edge shift. The defects inside the channel have been introduced to obtain high Q-factor by defect radii tailoring. The highest average Q-factor and sensitivity of 1570 and 249.5 have been obtained for defect hole with radius of rc = 0.34a. The study has been carried out by plane wave expansion and finite difference time domain analysis. There is a good agreement between the results and the study proves the effect of slow light on the enhancement of light-matter interaction and sensitivity. The proposed structures can find potential applications in gas or liquid detection in medical and biochemical fields.

(m, r) graph
Authors: Pramesti E A , Purwanto  
Published: May 2021

Abstract
A graph labeling is an assignment of integers to vertices or edges of a graph subject to certain conditions. There are various kinds of graph labeling, one of them is an odd harmonious labeling. An odd harmonious labeling f of a graph G on q edges is an injective function f from the set of vertices of G to the set {0,1,2,…,2q - 1} such that the induced function f*, where f* (uv) = f(u) + f(v) for every edge uv of G, is a bijection from the set of edges of G to {1,3,5,…,2q - 1}. A graph is said to be odd harmonious if it admits an odd harmonious labeling. A graph Sn(m, r) is a graph formed from r stars, each of which has n + 1 vertices, and every center of the star is joined to one new vertex v
0 by a path of length m. In this paper we show that the graph Sn (m, r), m ≥ 2, 1≤ r≤3, is odd harmonious.
Elegant labeling of sun graphs and helm graphs
Authors: Maulidia A R , Purwanto  
Published: May 2021

Abstract
Let G be a simple and finite graph having q edges. An elegant labeling f of G is an injective function from the set of vertices of G to the set {0,1,2,…,q} such that the induced edge labels, where each edge xy is assigned the label f*(xy) = f(x) + f(y) (mod(q + 1)), are distinct and non zero. If a graph can be labeled by an elegant labeling, then the graph is said to be elegant. In this paper we show that sun graph n-sun and helm graph Hn
, where n is an odd integer at least 3, are elegant.

Authors: Trisanti Y , Nusantara T 
Published: May 2021

Abstract
In this article we discuss about anti-fuzzy line graphs regular. The concept of antifuzzy line graph is an extension of the definition of the line graph concept. We adapt the concept of degree of vertex and degree of edge from similar definitions in fuzzy graphs. Furthermore, with this basic concept, we derive the regularity properties of the anti-fuzzy line graphs. Even the complete anti fuzzy graph is isomorphic and homomorphic to the anti-fuzzy line graph.

Abstract
From the concepts of clean index of rings, nil clean index of rings, and weakly nil clean index of rings, we expand them by introducing the new concept, that is, trinil clean index of a ring. From any element a of a ring R with unity, we set τ(a): ={e ∈ R|e
3 = e and a − e ∈ Nil(R)}, where Nil(R) is the set of all nilpotent elements of R; trinil clean index of R is defined by sup{|τ(a)||a ∈ R} and it is denoted by Trinin(R). In this article, it will be investigated some properties of trinil clean index of any ring, ring homomorphism, and direct product. Some applications of determining trinil clean index of integral domains are also provided. We also determined the trinil clean index of ℤ

Authors: Nafaati A M , Utomo R A , Hasanah D 
Published: May 2021

Abstract
The amount of hybrid chicken eggs production and consumption in Indonesia shows that the need of hybrid chicken eggs increases every year. Pamekasan is a district with the highest production for hybrid chicken eggs in Madura. This study aims to analyze the price elasticity of hybrid chicken eggs demand in Pamekasan and in Indonesia as well as to analyze the factors that dominate the elasticity. That is expected to become one of the bases for establishing policies in the livestock sub-sector, both on national and regional scale. The data being used in this study is the number of requests and prices for hybrid chicken eggs in Pamekasan and in Indonesia in 2016-2017 which were obtained from the East Java Provincial Animal Husbandry Department, Ministry of Agriculture, and the results of research by Ilham and Saptana in 2019 to obtain price elasticity. The price elasticity of demand of hybrid chicken eggs in Pamekasan was 20.68344657 which was elastic, while in Indonesia it was 0.795585317 which was inelastic. Based on the statistical analysis factor result, the factor that dominates the elasticity of the demand for hybrid chicken eggs in Pamekasan is the price of duck eggs with a correlation of 0.994.
Projection pursuit regression in statistical downscaling model using artificial neural network for rainfall prediction
Authors: Farikha E F , Hadi A F , Anggraeni D , Riski A 
Published: May 2021

Abstract
Rainfall prediction is important for farmers to be used in making policies, especially in areas of agricultural production, include in Indonesia. The availability of information about rainfall requires an accurate forecasting method. The General Circulation Model (GCM) is used in dynamic prediction to obtain rainfall information for one month, but with its low resolution, this model cannot be used to obtain information on a small scale so that a statistical downscaling (SD) model is needed. The Projection Pursuit Regression (PPR) used in this SD includes nonparametric and nonlinear approaches to processing large dimensional data that can describe small dimensions through a projection process. This research is further explained using a neural network-based approach, that is Artificial Neural Network (ANN) in a statistical downscaling model with applications for analysis of events related to rainfall prediction. In this case, the data will be part of the model formation of statistical downscaling. The SD prediction model uses several predictors, where some of these predictors have a physical relationship between the atmosphere and rainfall. The predictor variables are taken from the GCM output, the predictor variables used precipitation.
Naive bayes methods for rainfall prediction classification in Banyuwangi
Authors: Azmi A U , Hadi A F , Anggraeni D , Riski A 
Published: May 2021

Abstract
Banyuwangi is the largest district in East Java with an area of 5,782.50 km2. It has a long coastline of about 175.8 km which stretches along the southern eastern boundary of Banyuwangi Regency, and there are 10 islands. The BMKG estimates that the dry season in the Banyuwangi area is due to the appearance of the beach having hot weather and rarely rains. Banyuwangi also predicts that the dry season is due to the slight influence of cloud growth. Rainfall is a factor of the rainy season which has a big influence on life such as aviation, plantations and agriculture. Agriculture and plantations in Banyuwangi are mostly located in remote areas. Remote areas are likely to lack weather and climate data information. climate elements of a region cannot be ignored, especially rainfall. Based on data from BMKG (Meteorology, Climatology and Geophysics), the weather data used needs to be classified. Rainfall classification can be categorized into three, namely, light, normal and heavy. There are quite a lot of classification methods, there are several new methods that are quite good such as Naive Bayes (NB). Naive Bayes Classifier (NBC) is an algorithm in data mining techniques that is used to determine the probability of a member of a group. Large and irrelevant datasets can be solved using the Naive Bayes Classifier (NBC) method. The rainfall data used is known first, observed then identified to form a training dataset. Determining the accuracy of rainfall with the Naive Bayes Classifier (NBC) can use several parameters that have a physical relationship between the atmosphere and rainfall. The parameters used to determine rainfall are humidity, rainfall and precipitation. From this study, from 49 data testing, 47 data were predicted correctly with an accuracy of 96%.
Zero inflated poisson regression analysis on imb ownership in Sidoarjo regency 2019
Authors: Permadi H , Maulidah S D 
Published: May 2021

Abstract
The ownership of IMB is caused by several factors that can be seen by statistical analysis, but in this case, the data is Poisson distribution so the modeling uses Poisson regression. However, the assumption of equidispersion in Poisson regression is often difficult to fulfill, resulting in a case of overdispersion. The alternative to solve the overdispersion case is Zero Inflated Poisson Regression. This study uses the number of data in each village in Sidoarjo Regency with 8 factors that are suspected to influence it, namely the number of standing buildings larger 40th (X1), Land Certificate (X2), Knowledge of IMB (X3), Knowledge of Sanctions (X4), Costs (X5), Lazy or Convoluted Bureaucracy (X6), and the Feeling of Calm in owning a building (X7), and Participation in the IMB Socialization Program (X8).

Numerical solution of Saint-Venant equation using Runge-Kutta fourth-order method
Authors: Sukron M , Habibah U , Hidayat N 
Published: May 2021

Abstract
The Saint-Venant Equation (SVE) is the equation that describes the flow below a pressure surface in a fluid in unidirectional form. The SVE is in the form of partial differential equations. To solve the partial differential equations is rather complicated than the ordinary differential equations analytically and numerically. In this paper, we construct numerical schemes of the SVE by changing it into semi-discrete equation by using a finite difference in space (x) such that the SVE becomes ordinary differential equations (ODEs). Furthermore we solve the semi-discrete form of SVE by using Runge-Kutta fourth-order method since this method has smaller error and higher accuracy than the others method to solve ODE.

Published: May 2021

Abstract
This research examines a dynamic model, namely the Totally Asymmetric Exclusion Process (TASEP). In addition, it discusses the boundary conditions and dynamic rules used in this modeling. TASEP has been applied in various fields, one of which is the traffic flow modeling. This system is modified into a unidirectional fly-over fork. Furthermore, a vehicle which travels through a road segment is modeled as a particle which jumps from one lattice to another. The continuity term which is to describe a particle dynamic in TASEP is solved by using the level set method. The profile of particle density and current density is affected by input rate and output rate of the particle jump.

The mathematical model describing the centrally symmetric stress-strain state of an inhomogeneous elastic spherical body under the action of uniform all-sided compression is constructed. Approximate analytical solutions are found. The inhomogeneity of the elastic characteristics of the material is modeled by a radial non-monotonic elastic modulus at a constant Poisson’s ratio. Based on experimental data, the components of the stress-strain state are numerically calculated for the problem under consideration, and characteristic effects are revealed.

Published: May 2021

Abstract
A piecewise-linear problem of the effect of a wave propagating in soil on an extended underground pipeline interacting with soil according to the model of an “ideal elastoplastic body” is solved by the finite difference method. The results of calculating the velocities, strains and lateral shear stress for three waveforms: step-like, impulse and harmonic ones are presented. The analysis of the results obtained is performed and the effect of reverse outward forcing of the pipeline under the action of a displacement impulse propagating in soil in the form of sine squared is shown. An approach to the stationary mode under sinusoidal impact is considered.

Abstract
The paper considers the solution of linearized equations of the theory of small elastic-plastic deformations in the case of an axisymmetric problem. It is assumed that in the initial state there is a simple stretching. In the first approximation, the relations for the components of displacements, deformations and stresses are obtained. Solutions are expressed in terms of zero-and first-order Bessel functions. The paper deals with the stretching of an infinitely long cylindrical rod of variable cross-section.
