Photo-translation
Authors: Mersmann Birgit 
Published: June 2020

Abstract
This article introduces the concept of ‘photo-translation’ for studying documentary photography as a collaborative practice of visual translation. The visual-translational approach to photo documentation is applied in a novel way to the emerging field of contemporary migration photography, thus relating recent theoretical connections between translation and migration studies to explorations in visual studies. The study discusses how participatory and collaborative practices are increasingly used in contemporary photo documentation to challenge, if not remove, the relational ‘othering’ effect inherent in the photo-documentary representation of refugees, migrants and displaced peoples. The potential of translaboration as a mode of translational collaboration is explored through an in-depth analysis of two photo projects: (1) the participatory photo project Fotohistorias (Gomez and Vannini 2015), conducted by social and information scientists Ricardo Gomez and Sara Vannini in cooperation with migrants at the US–Mexico border; and (2) the collaborative photo–graphic novel project Lampedusa: Image Stories from the Edge of Europe (Migrant Image Research Group 2017), carried out by the Migrant Image Research Group under the guidance of Armin Linke. Demanding agency in visual translation proves to be essential for these participatory photo projects, since they aim to challenge dominant visual representations of how migration is narrated and represented in the media and academic discourse. For this reason, the investigation draws on new sociological approaches in Translation Studies in order to frame photo-translation as a social practice and as a form of (activist) engagement involving various agents and institutions.
Food provenance: assuring product integrity and identity
Authors: Wallace Carol Anne , Manning Louise 
Published: June 2020

Abstract
Food supply chains are highly complex and involve numerous actors who influence food safety and the integrity of products and processes, both at individual points in the supply chain and more holistically throughout the chain as a whole. Provenance can relate to a particular source or origin of a food and its individual ingredients, and/or relate to claims on how the product is produced and what marketing claims have been attached to the product. The aim of this review is to consider the recent advances in developing transparent data systems to demonstrate food provenance. One technological development is the use of Blockchain, a data handling structure that provides a secure network of information that cannot be changed or destroyed, distributed between supply chain actors. Other developments in information systems that can be used to monitor a range of criteria include geographic information systems (GISs) that can be linked with, for example, stable isotope analysis to provide an indication of provenance for a given product or ingredient. This technology is used as a case study in this paper to demonstrate the opportunities and limitations to such technological approaches. The review reflects on aspects of provenance and the actions that can be taken at organisational and supply chain level to demonstrate transparency so that consumers can have trust in those procuring, processing and supplying food.
Salvinia molesta
D. Mitch. (Salviniaceae): impact and control
Authors: Coetzee Julie A. , Hill Martin P.

Abstract

Salvinia molesta
D.S. Mitchell (Salviniaceae) (giant salvinia), a floating aquatic fern of Brazilian origin, has been dispersed to much of the tropical and subtropical parts of the world since the mid-1900s, where it is invasive and damaging. Herbicide application and mechanical control of this weed are labor intensive and expensive, but biological control using the host-specific weevil,
Cyrtobagous salviniae
(Calder and Sands), provides an effective and sustainable solution. The weevil was first released as a biological control agent onto
S. molesta
in Australia in 1980 and has subsequently been released in further 22 countries affected by the weed. The biological control program against
S. molesta
has been an extraordinary success story where a single weevil species has resulted in the weed no longer being considered invasive in most countries in a relatively short time of under 3 years. Biological control in temperate regions of the world might require more time than in tropical and subtropical regions, and this difference is presumed to be due to greater winter mortality. Nevertheless, inundative releases of the weevil early in the growing season have resulted in more effective control and less dependence on herbicide applications. However, there are new records of infestations of
S. molesta
in particular in Africa, and these sites must be prioritized for biological control.
The Role of Physical Education in Developing Student Characters in the Industrial Revolution 4.0
Authors: Suparwoto  
Published: June 2020

Abstract
The physics paradigm includes symmetry, optimization and unification is a unity of human life. The paradigm contributes to the development of physics education, so it has a role in providing a frame of reference in the development of good character students. Three aspects of physics education that affect human nature include (a) habits and explorative abilities of the surrounding natural environment; (b) communication and mathematical representation in step for problem solving; and (c) habit in developing problem-solving using observation and experiment tools as well as manual or digital information processing. By linking these three aspects through implementation to the learning process in the classroom and based on honesty and goodwill of individuals, students can build products to think towards good character. Rational considerations by physics thinking, always trying to be grateful and patient in every step of life by students, have a role in personal development with noble character.

Published: June 2020

Abstract
This research aims to describe performance of university physics students in the field of geoscience, focusing on assessment of students’ ability in field-practice implementation associated with geoscience learning to solve corresponding problems in the society living nearby the volcano. The present study involved a total of 32 students in the year 3 of their study, performing field work relevant to geoscience themes in Mount Kelud, well known as Tourism Park in East Java province, Indonesia. Based on the assignments distributed over the students during practising research skills, we concluded that students’ performance was overall good, indicating that they were well-trained. However, further improvement of the skills was required for at least two competencies, namely ability to assess critical information from the source and to both analyze and synthesize relatively new knowledge and hence different perpectives obtained on site. Following the research results, we hereby recommended that the field-based approach in geoscience learning is of significance in supporting improved performance and better research skills of university physics students.

The Geometry Effect of Regular Polygonal Wire on Its Inductance for Antenna Application
Authors: Bustomi M A , Pramono Y H 
Published: June 2020

Abstract
One important parameter of an antenna is its inductance. Inductance is the nature of a conductor which is related to its magnetic characteristics when alternating electric current is flowed. There are several factors that affect the inductance of a conductor wire, such as the size (dimension of the wire), the geometric shape of the wire, the permeability of material around the wire, and others. In this paper, we will discuss the effect of wire geometry on the value of the wire inductance. The wire diameter of regular polygonal wire is very thin. In determining the inductance of regular polygonal wire, some restrictions do for simplification in the calculation. Some of these restrictions are (1) the length of wire or circumferential polygon is fixed, (2) the diameter of the wire is considered very thin, (3) the distribution of the magnetic field is considered homogeneous, (4) the effect of external magnetic fields on the wire ignored. The results of calculations and analysis show that the change in geometry of regular polygonal wire from rectangular wire to decagonal wire causes the wire’s inductance value to increase.
Using Four-Tier Multiple Choice Diagnostic Test to Identify Misconception Profile of 12th Grade Students In Optical Instrument Concepts

Published: June 2020

Abstract
During physics learning process, quite often students experience a misunderstanding between their initial knowledge on certain concept in physics and that was taught in class by teacher. For example, students’ initial knowledge on Optics was that a white object can emit light so that someone can see the object even though the object is in a dark room. Meanwhile, in Physics concept, an object can only be seen by eyes only when there is light that hits the surface of the object and the light is reflected back by the object in all directions, including reaching to the eyes. This misunderstanding quite often leads to misconceptions. Such misconceptions should be detected as early as possible so as not to disturb student’s understanding on the other concepts. This present study aims to analyse the misconceptions profile of 12th grade students in Senior High School 1 Cerme Gresik East Java in “Optical Instruments ” concepts using the developed four-tier multiple-choice diagnostic test. Identification on the causes of students’ misconceptions, especially that arising from theirselves was also presented. The most frequent misconception found is on the sub concepts of: 1) “Eye and Camera” caused by student’s wrong preconceptions, 2) “Lup” due to associative thinking and 3) “Microscope” due to intuitive thinking. Meanwhile, for the “ Binocular” concept, almost all students have had scientific conception, meaning that they have understood the concept well.
Application of the Thermodynamic System to Analyze the Relationship of the Money Amount Circulating Against Inflation

Published: June 2020

Abstract
Based on an analogy between thermodynamics and economic theories, one of many economic problems can be represented by the ideal gas equation. Scientists have considered modifying the formulae from an ideal gas in thermodynamic principle to be applied to economic problems. An ideal gas is composed of many molecules. This ideal gas with the outside environment limited by the boundary system. Therefore, this gas is only contained in a volume so that this gas will exert pressure on the walls of the system. The gas molecules will vibrate and move about faster so they will increase their rate of exchange of kinetic energy. Since this gas also accumulates internal energy, an increase in temperature will be generated in this process so pressure and volume potentially increasing too. An equation of ideal gas has a similar structure to the equation of an economic system. Many molecules are assumed as monetary carriers or holders of value, equivalent in size to units of currency. The relationship of the system with the outside environment is that the value held by carriers or holders can be exchanged for goods and services at the boundary system at price (as pressure) and volume over a period of time, according to an index (or a degree of a scale) of trading value (as temperature) with which they can do this over that period. The objective of this study was to obtain inflation index value (m), to find out the inflation rate in Indonesia in that year and to analyze the causes and solutions for the better in the following year. The economic analysis of inflation is applied to the ideal gas theory. The parameters needed to be the money supply, the price index, and the speed of the money supply. The calculation and analysis with this ideal gas equation showed that all parameters used were affecting each other. The data from the last ten years showed that there was a significant change in the value of elasticity index value (n) for 4 times. All changes were in different time frames. Based on the ideal gas theory, a good value of n was a value of n that is less than or equal to one.

Published: June 2020

Abstract
Nuclear physics is one of the theories in the field of physics that aims to study the structure of atomic nuclei, the interactions between the compilers of atomic nuclei, and the underlying forces. This study aims to obtain a model of interaction that occurs between nucleons. The interactions between these nucleons are modeled by a binary center of mass system (two objects) and their potential experience is expressed by the Woods-Saxon potential with certain parameters. The obtained model equations are then solved using the fourth-order Runge Kutta numerical method that programmed in the Matlab programming language. In this study, this model used has been simulated on the interaction of nucleons in Deuteron, Triton, Helium-3 isotope, and Helium works well, but it did not work well in Lithium atom.

Possible Detection of Magnetic Anomaly During Tsunami Events in Indonesian Regions Using Global Magnetogram Records
Authors: Prastowo T , Madlazim  , Cholifah L 
Published: June 2020

Abstract
Ocean flow generates secondary, weak magnetic signals relative to the main field induced by the Earth spinning motion, where the secondary signals lead to magnetic anomaly. The anomaly were apparently observed as short-lived variation in secondary field components, namely the vertical bz
and horizontal components bH
, respectively, during tsunami occurrence. In this study, maximum amplitudes associated with these components were determined using theoretical approaches and field records on global magnetogram provided by INTERMAGNET and BCMT. The roles played by a depth ratio of h/L where h and L are the ocean depth and characteristic length, respectively, and a speed ratio of c/cs where c and cs are the speed for linear long wave solution and the complex speed involving ocean diffusion, respectively, are here examined using Indonesian case studies of tsunami with respect to trans-Pacific tsunamis as reference. For cases with advection dominance, it was found that frozen-flux theory can be used to estimate bz and bH, consistent with values provided by the global magnetic institutions. In short, whereas bz is a measure of water surface elevation and hence tsunami height offshore, bH is an indicator for tsunami propagation direction. Detection of magnetic anomaly prior to tsunami arrivals at coastal zones is thus possible, making it crucial for tsunami early warning.

Published: June 2020

AbstractThe plant’s wastes can be recycled as a source of natural fiber to fabricate biodegradable films. The utilization of natural waste cornhusk for the production of environmentally friendly mulch was studied. The cellulose of cornhusk can be extracted with alkali treatment so that the cellulose produced can be used as a material for mulches. The mulch film can be synthesized with a variation content of cornhusk cellulose at 5,10, and 15 %, Low Linear Density of Polyethylene (LLDPE), variations in anti-UV concentration (1,4, and 6 %) and the addition of additives using the extrusion-calandering method. Variations in the added anti-UV concentration could affect the optical and mechanical properties of the mulch film produced. The mulches film produced has a black color, smooth and elastic surface. The mechanical properties of the film have increased. Significant tensile strength 20.75 MPa, elongation 354 % and modulus of elasticity 0.62 GPa were found in films with the addition of 4 % tinuvin concentration and 15 % cellulose content. The addition of anti-UV resulted in a shift in the peak in the UV range so that no dominant peaks appeared for T1, T4, and T6 mulches. The mulches film T4 at 5 % cellulose content absorbs maximum light at a wavelength of 300-400 nm. SEM analysis showed that the homogeneous mulch film morphology has a lump and is porous.

AbstractThis study aims to investigate site conditions based on the dominant period and elliptical curve inversion of Horizontal-to-Vertical Spectral Ratio (HVSR). The data were taken using a seismometer portable short period in the minimum time span of data retrieval for 30 minutes. The Nakamura method as known as Horizontal-to-Vertical Spectral Ratio (HVSR) is used to obtain the value of the dominant frequency and amplification factor. The dominant frequency is changed to the dominant period which can indicate the type of soil. HVSR processing use Geopsy software with a guide from the SESAME Project. The results of processing show that the dominant frequency and the amplification factor. In Geopsy there are several modules and packages. This processing uses TFA Module and Max2curve Package and Dinver Package. Waveform can be inversed based on the elliptical curve of HVSR model to produce a shear wave velocity model (Vs) uses that modules and packages. From the velocity model, we can know Vs30 to determine the type of soil layer. The shear wave velocity model obtained can show the estimation of sediment thickness in the area under investigation.

Published: June 2020

AbstractActive carbon/rGO based on natural materials as coconut shell has been assembled with a coin cell in shape of prototype supercapacitor. The physical feature of active carbon/rGO electrode were characterized by FTIR, and FESEM. The Electrochemical performance of supercapacitor in 1 M LiPF6 electrolyte solution with density current of 12 mA/g until 163 mA/g were analyzed by galvanostatic charge-discharge test. The result showed that active carbon/rGO had absorption peaks at wave numbers 1592.27 cm−1and 1288.45 cm−1which were functional groups as C = C and C-O. The morphology of activated carbon has been covered by the presence of rGO that determines the agglomeration of rGO around the pore of activated carbon so that it affects the performance of supercapacitors. Supercapacitor has a specific capacitance charging of 20.5 F/g, and discharging of 19 F/g in density current 12 mA/g.
