The Turkish state’s responses to existential COVID-19 crisis
Authors: Bakir Caner 
Published: June 2020

ABSTRACT
This article focuses on how the Turkish state has been responding to limit the public health effects of COVID-19 pandemic to date. It aims to explain and understand the introduction, implementation and effect of health policy instrument mixes. It argues that although ‘presidentialisation’ of executive, and ‘presidential bureaucracy’ under presidential system of government are critical to introduce policies and implement their instrument mixes without delay or being vetoed or watered down which would otherwise occur in the parliamentary system of government, these features of impositional and exclusive policy style pose risks of policy design and implementation failures when the policy problems are poorly diagnosed, their policy solutions are wrong and/or complementary policy instrument mixes implemented ineffectively. However, a temporal, albeit temporary divergence from a dominant administrative tradition and policy style is most likely when a policy issue is esoteric (i.e. technical, scientific and expert-led) and framed as an existential crisis under high uncertainty that require scientific, expert-led, inclusive, early, quick and decisive responses to pressing policy problems.

ABSTRACT
Technology is an instrument to build BRI relationships, mitigate the environmental and climate impacts of BRI projects, as well as to enhance environmental sustainability in the regions. This study aims to reposition China in global climate technology transfer in BRI era and to obtain initial knowledge on needs, priorities, and barriers from the receivers’ perspective. Focus group method with aid of questionnaire survey and follow-up face-to-face interviews was adopted to capture the major issues directly expressed by receivers from these countries. A total of 63 valid questionnaires were collected, and 13 respondents were face-to-face interviewed. The results confirmed that energy and agriculture were the most prioritized sectors for mitigation and adaptation in the developing countries alongside OBOR. The prioritized technologies for mitigation included cogeneration, solar photovoltaic, and biomass/biogas electricity. Irrigation, conservation agriculture, and soil management were prioritized for adaptation in agricultural sector, and water recycling and reuse, source water protection, and urban drainage management in water resource sector. Technology cost during installation and operation was stressed as the most important factor constraining the application and diffusion of climate technologies. But communication including language, information, and ways of communication, was also identified as an important factor. This implied that the conventional climate technology transfer need adapt to changing contexts of BRI and be complemented with innovative approaches involving multi-actors in different phases of climate technology development. Due to the limited representativeness of the sample, the results can hardly be generalized to all the countries, but raised interesting topics for future researches.

Quantifying uncertainties on fission fragment mass yields with mixture density networks
Authors: Lovell A E , Mohan A T , Talou P 
Published: June 2020

Abstract
Probabilistic machine learning techniques can learn both complex relations between input features and output quantities of interest as well as take into account stochasticity or uncertainty within a data set. In this initial work, we explore the use of one such probabilistic network, the mixture density network (MDN), to reproduce fission yields and their uncertainties. We study mass yields for the spontaneous fission of 252Cf, exploring the number of training samples needed for converged predictions, how different levels of uncertainty propagate from the training set to the MDN predictions, and how well physical constraints of the yields—such as normalization and symmetry—are upheld by the algorithm. Finally, we test the ability of the MDN to interpolate between and extrapolate beyond samples in the training set using energy-dependent mass yields for the neutron-induced fission on 235U. The MDN provides a reliable way to include and predict uncertainties and is a promising path forward for supplementing sparse sets of nuclear data.

Published: June 2020

Abstract
The method of rapidly measuring the somatic cell count of raw milk is important for detecting the quality of milk and monitoring the health of dairy cows. This paper investigates a vision-based measurement algorithm and develops an instrument for measuring the somatic cell count. In detail, first, microscopic images of glass slides are automatically captured. Second, the Hough transform is used to calibrate the microscopic image so as to compute the sample volume. Third, a discrete optimization model is set up to determine the image segmentation threshold. Fourth, the features of milk somatic cell are expressed in area, ratio of length to width and circularity. The least-square circle method is employed to detect the circularity of the milk somatic cell. Then, an automatic milk somatic cell count is achieved via a recursion algorithm. Finally, a milk somatic cell counting instrument is developed based on the proposed algorithm, which is verified to be applicable via comparison with the FossMatic 5000, made in Denmark.

Published: June 2020

Abstract
Metal halide perovskites having three-dimensional crystal structures are being applied successfully in various optoelectronic applications. To address their most challenging issues—instability and toxicity—without losing efficiency, lower-dimensional perovskites appear to be promising alternatives. Recently, two-dimensional (2D) perovskite solar cells have been developed exhibiting excellent photostability and moisture-stability, together with moderate device efficiency. This review summarizes the photophysical properties and operating mechanisms of 2D perovskites as well as recent advances in their applications in solar cell devices. Also presented is an agenda for the next-stage development of stable perovskite materials for solar cell applications, highlighting the issues of stability and toxicity that require further study to ensure commercialization.

Published: June 2020

Abstract
In this article, a DFT study is carried out to explore the electronic, structural and optical properties of SrZrO3 (SZO). Zn is doped at Sr site in minimum quantity to explore the minimal effect of Zn on electronic behaviour and its impact on other properties. For investigation of these properties, Ultrasoft pseudopotentials (USP) and Generalized Gradient Approximation suggested by Perdew, Burke, and Ernzerhof (GGA-PBE) functional is executed. The inclusion of Zn at Sr site in SZO affects the electronic and optical properties significantly. Band gap was expressively reduced from 3.315 eV to 2.618 eV which has direct impact with interacting energies. The nature of band gap for both intrinsic and doped systems remain indirect which means Zn inclusion did not affect the nature of band gap. The change in electronic properties due to addition of impurity leads towards change in optical properties. All the optical properties including complex dielectric function, absorption spectra, reflection coefficient, refractive index and extinction coefficient were calculated. The results showed a clear red shift in the absorption spectra along with peak shifting from 2.98 eV to 0.63 eV and the refractive index obtained for pure material is 2.13 which then altered to 2.45 due to doping. Doping of zinc in SZO significantly alter the electronic and optical properties and thus making it a valuable asset for optoelectronic devices.

Published: June 2020

Abstract
The ion wind drying method has been used to dehydrate potato slices with a variation of electric power and a constant drying time of 30 minutes. Ion wind drying is generated by an electrohydrodynamic flow reactor using 10 x 10 pairs of pin electrodes and multi-ring concentric electrodes connected by a DC high voltage. The high electric field in space between electrode causes ionization of air at the atmosphere condition which is produced ion flow together with heat transfer, and radical ions which are used for drying. Power in the reactor during drying is influenced by the input voltage and the measured current obtained a minimum value of 10 Watt and a maximum value of 60 Watt. Ion wind drying in the sample slices found also the value of the level of drying, shrinkage, humidity, and energy consumption which increases with increasing power at the reactor.
The use of raspberry pi as a portable medical image processing

Published: June 2020

Abstract
This paper presents the image processing implementation in Raspberry Pi. Raspberry Pi is a system built-in and is a low-cost computer that can be used to reduce system complexity in real-time applications. For programming, it’s very good to use Python. Raspberry pi has a Camera Slot Interface (CSI) to interface the camera with Raspberry Pi. Low contrast images captured using the Raspberry Pi camera module can be scaled up first to identify specific image regions. The most important processing is the removal of noise as a result of noise disturbance during image acquisition on the camera. Due to its small size, which is about the size of a credit card and its lightweight, raspberry pi is very suitable for use as a portable medical image processing system. Besides that Raspberry Pi also consumes low power.
Face geometry as a biometric-based identification system
Authors: Widodo C E , Adi K 
Published: June 2020

Abstract
In this paper, we present a method for identifying a person with a biometric-based on face geometry. This person identification system design has been done using face biometrics by implementing feature extraction of distances between facial features. Face biometrics were chosen because they have unique characteristics and do not change in each person. In this method, a system analysis that separates the face image into face components, including the eyes, nose, and mouth on the face image is taken from the front view position. Each component of the feature that has been detected is measured by its distance to form the face semantics. The steps taken in image processing begin with determining the region of interest (ROI). Furthermore, the results of cropping ROI feature extraction are done to get the eye, nose and mouth. After that, a centroid is determined for each feature so that the distance between features can be calculated using the equation of the distance between the two coordinates, so we get 8 distances as matching parameters. The matching process is done using euclidean distance, which is calculating the smallest distance between the test image and the database. Based on research results, this system can be used to identify someone using face biometrics with fixed poses and expressions. The accuracy of this system is 100 percent

Abstract
Fulfillment of nutrition for children under five years of age is a factor that needs to be considered in maintaining children’s health because in infancy it is a period of development that is vulnerable to nutritional status. Based on data from the Ministry of Health of the Republic of Indonesia in 2015 shows that the number of malnutrition is still high, as many as 185 in each province, and it is estimated that there are still around 12 million that have not been reported. The main problem with the high number of malnutrition status lies in the weakness of the recording and reporting process so that the government cannot have information that can be used to conduct early detection of the incidence of malnutrition. The weak process of recording nutritional status is caused by the lack of available instruments that can be used for the recording and reporting process. Based on the above problems, the Mozita application was used to process the recording and reporting of under-five nutritional status based on anthropometry tables. The Mozita application guarantees the accuracy, speed, and convenience in terms of knowing the early growth of toddlers. This study focused on measuring the quality of information on the Mozita application, which includes aspects of accuracy, timeliness, suitability, completeness, and ease of use. Measuring the quality of information is done by using questionnaires distributed to respondents (midwives), then for further analysis using the weighted average pre and post. The results of descriptive data analysis showed that the overall weighted average value of information quality pre Mozita application development was 1.01 and the post was 2.78. Pre and post value is the value of information quality which includes aspects of accuracy, timeliness, suitability, completeness, and ease of use. Comparison between pre and post values has increased by 1.77. An increase in the value of 0.63 can be interpreted that there is a positive influence on the quality of Mozita application information on aspects of accuracy, timeliness, suitability, completeness, and ease of use.

Authors: Griyanitasari G , Rahmawati D , Sugihartono  , Erwanto Y 
Published: June 2020

Abstract
Black-cube-gambir (pale catechin) is a processed gambir (Uncaria gambier) extract. Containing condensed tannin, black-cube-gambir could be used as a vegetable tanning agent in the leather making process. Some industries in Indonesia use pickled hide/skin as raw material for the next process that the previous bating process is uncontrolled. Therefore, this study aims to determine the effect of rebating in the re-pickle stage on the leather tanned with Uncaria gambir. For alum-gambir tanned leather, rebating increased its softness, tear strength, and hydrothermal stability, while for glutaraldehyde-gambir tanned leather, rebating increased its tensile strength, degree of tannage, and tannin bound. The broad DSC peak revealed that the distribution of collagen molecules of all samples was unequal. Rebating could increase and decrease the quality of leather.

Published: June 2020

Abstract
Ngempon Temple was discovered below the ground level caused by collapsed land in 1952 in Ngempon Village, Bergas Sub-district, Semarang Regency. The HVSR method is used in the three-component microtremor to identify the bedrock response frequency. Additionally, this method can be used to determine the dominant resonance frequency (f0) and the peak value of HVSR (A), which shows the dynamic characteristics of sediments. This study aims to determine the position and types of archaeological objects that are still hidden and make a modeling of the subsurface conditions. The method used in this study is a trapezoidal measurement geometry by measuring spaces within 2 meters. Data retrieval duration is 10 minutes for each point, and the specified frequency sampling is 10 Hz. The H/V curve generated from data processing will result in the frequency value and amplification that will be analyzed and linked to the Ngempon Temple archaeological data. The results obtained from this study indicate the existence of the temple’s fundamental rocks and rock debris model below the surface indicated by the contours of the HVSR spectrum profile. They are an amplification value of 1.3 and the response frequency with a sensitivity of up to 4 Hz from the surface, and an amplification value of 1.3 and the response frequency with a sensitivity of 5.8-10 Hz. The sensitivity to measurements is based on whether the response passes the excavation of BPCB Central Java. If it passes, then the response indicates an anomaly of the fundamental rocks. Vice versa, if the measurement does not pass the object of research, the response only shows the existence of temple rocks fragments. The amplification value and frequency of response shows a difference between the temple rock and the sediments above it.

Authors: Setiawati E , Juliawan S , Arianto F , Margiantono A 
Published: June 2020

Abstract
The HTR-10 is a gas-cooled high-temperature reactor with spherical fuel and moderator called pebble bed and operated on 10 MW thermal power. Until now, a lot of research and development on the HTR-10 in terms of neutronic computational modeling has been carried out, one of which is burnup analysis. Fuel depletion or burnup analysis is an analysis related to fuel control and reactor output power. This analysis is needed because changes in fuel composition will affect the neutronic parameter values of a reactor. The 10 MW HTR fuel depletion study has been conducted by modeling the reactor using MCNPX (Monte Carlo N-Particle e-Xtended) to analyze the effect of radius and enrichment of reactor fuel to the left value and the burnup rate. The study is conducted by modeling a 10 MW HTR with three sorts of fuel kernel radiuses using MCNPX. First, 250 μm radius, second, 275 μm radius, third, 300 μm radius and all radiuses are variated with 10-15% fuel enrichment. TRISO particles are dispersed using simple cubic (SC) lattice in the fuel zone. The fuel balls are allocated in the reactor core along with moderator balls using a body-centered cubic. To perform all the calculations, MCNPX utilizes continuous energy data library ENDF/B-VI. From the calculation result using MCNPX can be concluded that the kernels with the radius of 275 μm and 300 μm at 14% and 13% fuel enrichment respectively were more able to maintain a critical condition within a year of operation than the kernels a 250 μm radius and the fuel with 250 μm radius has the highest burnup rate that is 52,07 GWd/MTU.

Abstract
The development of electrooptic devices by strengthening the electromagnetic fields using colloidal silver has been carried out. This tool works based on the electrooptics method. The samples used were aquabides and a solution of aquabides mixed with colloidal silver with various concentrations. The light source used is a green laser with a wavelength of 532 ± 10 nm. Measurements are made by observing changes in the natural polarization angle and the electro-optical polarization angle. The test results show that at a concentration of 0-0.25 there is a significant change in the polarization angle to the increase in the external electric field (0-9 kV). While at a concentration of 2.5-1 there is a tendency that there is no change in the polarization angle.
Effects of repetition rate on the identification of elements in gemstone using the LIBS method
Authors: Bagaskara A , Soesanto Q M B , Sugito H , Khumaeni A 
Published: June 2020

Abstract
In material science, there are several methods for detecting elemental content in a material (sample) such as X-Ray Fluorescence (XRF), (X-Ray Diffraction) XRD, (Scanning Electron Microscope) SEM, (Transmission Electron Microscope) TEM), etc. Non-metallic samples such as gemstone can be detected by XRF and XRD methods. But in this method, the sample must get special treatment such as being crushed and converted into powder form. In this study, LIBS was used to identify elements in a gemstone. The laser-induced breakdown spectroscopy (LIBS) method is an alternative method for solving deficiencies in the previous study. The results show the same elements contained in the gemstone can clearly be detected. The elements are also confirmed by using the standard technique of X-ray fluorescence and the result revealed that the elements are consistent as in the case of the LIBS technique.

Published: June 2020

Abstract
Signal to Noise Ratio (SNR) is one of the quality control tests for most diagnostic imaging modality, including Magnetic Resonance Imaging (MRI). This study used MRI 1.5T GE Signa Creator type and head coil phantom with variations of Echo Time (TE), Repetition Time (TR), voxel volume and flip angle. 16 data images were obtained from the acquisition process. These images were analyzed using image processing software to calculate the SNR value. It results in four data distribution with the highest value of 36.98 and the lowest value of 32.64. The graphs of voxel volume versus SNR also formed four groups of data with an overall value above SNR baseline value for daily operation.
