The Advanced Learning Platform for Analog Circuits and Automation for hybrid electronic practicals
Authors: Docter M W , Bastemeijer J 
Published: March 2024

Abstract
To maintain experimental lab course work during the COVID-19 lockdowns, we chose a hybrid approach for our electronic instrumentation course and developed thereto the Advanced Learning Platform for Analog Circuits and Automation (ALPACA). To further meet our goals and standards, the ALPACA platform has been updated, using a Raspberry Pi Pico with Python instead of an Arduino. Our educational materials and approach are illustrated here through the typical example of a relaxation oscillator assignment. As student’s feedback was overall positive and grades remained comparable, we continue the use of the ALPACA in the non-COVID era.
Video clips in physics education
Authors: Greczyło Tomasz 
Published: March 2024

Abstract
Film recordings – video clips – have been used in the teaching and learning processes for decades. At the very beginning, the dominant role was played by television and professionally prepared recordings on portable media (e.g. LaserDiscs). With the advancement of technology and the emergence of new media, as well as the revolution in access to image and sound recording and processing devices, video clips – including amateur ones – have become the dominant path of contemporary visual communication. The paper is of an overview character and discusses examples of educational use of video in physics education in the past and at present, including TV lectures, popular science programs, dedicated video materials and educational environments, software for video measurement and evaluation of learning outcomes. Various illustrations along with literature references are given to outline potential educational pathways in making use of video clips as didactically valuable medium in teaching - learning physics.
Usage of Augmented Reality in Physics Education: Erasmus+ KA201 Project ARphymedes
Authors: Dolenc S , Susman K , Pavlin J. 
Published: March 2024

Abstract
School physics is often mentioned as one of the least preferred subjects because the concepts can be complex and difficult to understand. At the same time, experiments are an important aspect to illustrate the process/concept/phenomenon, but there is often not enough time to do so. An interactive way that could increase students’ motivation during these times and allow them to deepen their knowledge of physics is through the use of augmented reality. The aim of this paper is to present the project AR Physics made for students (acronym: ARphymedes), which addresses the above problem.

The MUonE DAQ: online track-finding and
event selection in hardware at 40 MHz
Authors: Magherini Matteo ,   the MUonE collaboration
Published: March 2024

Abstract
High-intensity particle beams provide a significant challenge to DAQ systems, especially in complex architectures reading out many sensors. The MUonE experiment has been conducting beam tests using the M2 muon beam at CERN, with in-spill intensity of 5 × 107 muons/s, using tracking modules equipped with silicon strip sensors and a module readout bandwidth of 5 Gb/s. A pilot run has been performed in late summer 2023, incorporating several such modules arranged in three tracking stations and a prototype of an electromagnetic calorimeter connected to a triggerless readout system. Limits on processing and data storage will necessitate online event selection to be implemented in hardware, on state-of-the-art AMD-Xilinx UltraScale+ FPGAs.
The status and plans of the MUonE DAQ operation will be presented, outlining a general purpose platform for online event selection, from simple occupancy cuts, to track reconstruction, vertexing, and particle identification.

Authors: Ge Zhenwu , Zhang Jie , Zhang Lei , Han Liangliang ,   the ATLAS HGTD collaboration
Published: March 2024

Abstract
This paper introduces an FPGA-based front-end module emulator developed for the High Granularity Timing Detector (HGTD) within the ATLAS experiment at LHC. The emulator serves as a debugger for the HGTD readout system during the stage when the front-end module is not available. Using a Xilinx-Spartan 7 FPGA, the emulator mimics the behavior of the ASIC utilized in the front-end module. In addition, it shares the same dimensions and connectors as its successor, the real front-end module. This emulator has been effectively employed in the design and testing of the HGTD.

Abstract
Collective Thomson Scattering (CTS) diagnostics measure the scattering spectrum of monochromatic incident radiation off collective fluctuations in the plasma. In this contribution, we present the first results from the upgraded CTS diagnostic at Wendelstein 7-X (W7-X) operating in the frequency range between 172 and 176 GHz. This frequency range allows for minimization of noise originating from the electron cyclotron emission in the plasma. Consequently, the good signal-to-noise ratio allows measurements of fast ions or bulk plasma parameters with higher temporal resolution compared with the previously used 140 GHz system.
Optimization of pulse shape discrimination based on frequency domain for SiPM-based NaIL scintillator detector
Authors: Li JunYu , Fan Peng , Zhu ChengLin , Wang MengMeng , Wei ZhiYong , Xia Yan 
Published: March 2024

Abstract
Frequency gradient analysis (FGA) neutron-gamma pulse shape
discrimination (PSD) based on Fourier transform has proved to be an
effective method for discrimination between two types of pulses by
simply constructing a discrimination parameter by subtracting the
amplitude of the 1st frequency component from the 0th frequency
component. However, the discrimination parameter constructed by the
above method could not meet the requirements at some lower sample
rates, and the dark noise caused using optoelectronic devices such
as miniaturized SiPMs array further erodes the difference between
the two frequency components. This paper proposes a new
discrimination parameter construction method based on FGA for
neutron-gamma discrimination, which is referred as mFGA (modified
FGA). This discrimination parameter uses the 0th frequency component
and other frequency components to enhance the discrimination
performance. A neutron detector module consisting of a
25.4 mm× 25.4 mm× 50.8 mm
NaI:Tl,6Li (NaIL) scintillator and an array of 8 × 8
SiPMs was established to verify the method of mFGA. The module
measured a 252Cf neutron source under three shielding
conditions: no shield, 5 cm high-density polyethylene (HDPE), and
10 cm lead brick. The proposed mFGA method was used to calculate
the figure of merit (FoM) under each shielding condition and
compared to the traditional frequency gradient method (FGA) and the
traditional charge comparison method (CCM). The results show that
the discrimination performance with the mFGA method is significantly
improved. Taking the HDPE shielding group as an example, the
performances of the three methods are FoM-FGA =1.14,
FoM-mFGA =2.75, FoM-CCM =0.92. At the same time,
with the increase of energy, due to the neutron gamma pulse becoming
similar, and the discrimination performance of FGA and CCM decrease
significantly. The discrimination performance of the mFGA method is
relatively stable in all energy regions. Therefore, the proposed
method is superior to the traditional FGA of the 0th frequency minus
the 1st frequency and has a good application prospect for
neutron-gamma discrimination with detectors of poor signal quality.
Spot-based measurement of the brighter-fatter effect on a Roman Space Telescope H4RG detector and comparison with flat-field data
Authors: Plazas Malagón Andrés A. , Shapiro Charles , Choi Ami , Hirata Chris 
Published: March 2024

Abstract
We present the measurement and characterization of the
brighter-fatter effect (BFE) on a NASA Roman Space Telescope
development Teledyne H4RG-10 near-infrared detector using laboratory
measurements with projected point sources. After correcting for
other interpixel non-linearity effects such as classical
non-linearity and inter-pixel capacitance, we quantify the magnitude
of the BFE by calculating the fractional area change per electron of
charge contrast. We also introduce a mathematical framework to
compare our results with the BFE measured on similar devices using
autocorrelations from flat-field images. We find an agreement of
18 ± 5% between the two methods. We identify potential sources
of discrepancy and discuss future investigations to characterize and
address them.

Published: March 2024

Abstract
Lunar water ice is an important resource to support the
construction of lunar base and other deep space activities, and it
is crucial to detect lunar water ice. In this paper, we studied the
detection of lunar water ice based on a small neutron generator
through Monte-Carlo simulation. The schematic of the detection
system and the principle are explained. The simulation results
demonstrate that the change of thermal neutron flux with the
increase of water content is most obvious and clear. There is a
positive correlation between thermal neutron counting and water
content in lunar soil. Using thermal neutron counting, the water
content can be obtained by inversion.
Safe Yield of Groundwater Utilization for Domestic, Livestock and Hotels Requirement as An Anticipation of Sea Water Intrusion in The Coastal of Batang Regency
Authors: Puspa Lestari Adjeng 
Published: March 2024

Abstract
As a result of the groundwater utilization which exceeds its safe yield, the phenomenon of seawater intrusion is often found in some coastal areas. For this reason, the utilization of groundwater must not exceed its safe yield. This study aims to calculate the availability of groundwater and its safe yield and evaluate its utilization which does not exceed the safe yield. To achieve this purposes, groundwater availability is calculated using the static method by multiplying the area by the thickness of the aquifer and the specific yield. Utilization of groundwater for domestic, livestock and hotel requirement is carried out by multiplying the water demand for each of these sectors by the amount. Safe yield is calculated based on area width, groundwater fluctuation and its specific yield. The groundwater resources potential of research area amounted to 648,960,234 m3/year, while the safe yield was 127,702,334 m3/year. Utilization of groundwater for domestic, livestock and hotel requirement is 23,062,023 m3/year, so that the use of groundwater to meet domestic, livestock and hotel reqirement has not endangered the availability of groundwater. However, for Batang District, groundwater utilization has almost reached half of its safe yield.
Resonance of Local News Media Regarding Water Pollution Management In Yogyakarta Regency: A Review
Authors: Firdhausi A I , Islami F , Pratama M A 
Published: March 2024

AbstractYogyakarta faces challenges in maintaining water quality due to the presence of pollutants E.coli as a resulting dominant bacteria. The information provided by the media is easily understood when it is based on the needs of the community. The emergence of various local news media outlets becomes a solution to address the existing issues in society. The local news media in Yogyakarta has not yet made a significant impact on the environment, particularly in water resource management, as evidenced by the numerous complaints from the community regarding water quality. Primary data of this research is gained through qualitative content analysis and in-depth interviews with journalists of local news media outlets in Yogyakarta, namely harianjogja.com, krjogja.com, and tribunjogja.com, and twelve journal articles in the period from 2019 to 2023. The findings are Harian Jogja, Tribun Jogja, and Kedaulatan Rakyat, demonstrate insufficient resonance in their coverage of water source pollution management. This is evident through several factors: limited frequency of news coverage, absence of dedicated desks within the editorial teams, lack of specific sections dedicated to environmental topics, low traffic generated by related news articles, and a lack of specific attention from editors regarding water pollution management in terms of assignment and environmental education for journalists. The majority of news articles written by journalists in this context predominantly fall into the informative category, accounting for 71% of the coverage. In contrast, articles categorized as educational or solution-oriented are minimal. The findings of this research endeavor aim to contribute academically to the field of water pollution management by emphasizing the need to optimize the utilization of local news media in Yogyakarta.
Prediction of the future landuse and land cover changes in the Parangtritis sand dune : a spatio temporal analysis using QGIS MOLUSCE
Authors: Bramantio B , Hizbaron D R , Khakhim N 
Published: March 2024

Abstract
This study was aimed to analyze the changes and predict the future land use in the Parangtritis Sand Dunes, located in Bantul Regency, Yogyakarta Special Region, Indonesia. Parangtritis Sand Dunes face the threat of damage due to various human factors such as settlements, tourism, agriculture, plantations, etc. The Cellular Automata method, coupled with the Modules for Land Use Change Evaluation (MOLUSCE) plug-in, was employed to assess the dynamics of land cover/land use and make projections for the future. The analysis revealed significant changes in several land cover classes between 2019 and 2021, while others remained relatively stable. From 2019 to 2021, the change in area amounted to 5.6 hectares, while from 2021 to 2031 the change was only slight, amounting to 0.7 hectares. So it can be concluded that the change in the area of sand dunes in the future, namely in 2031, has not changed much, only increased by 0.7 Ha. So that more effort is needed to curb the core zone intended for the preservation of the Parangtritis sand dunes. Further investigation into the underlying causes of these shifts could provide valuable insights for effective land management and conservation efforts.

Published: March 2024

Abstract
Water resources of rivers and estuaries have traditionally been managed for local societal demands, including municipal, agricultural, and industrial usages, as well as for transportation as navigational channels. However, as societal demands have changed including urban expansion, economic growth, cultural transition, etc., the land uses also should be changed, and the civil necessities of water have been diversified, and this has raised concerns about the ecology, environment, and water quality issues. This study attempted to address three water resource management issues in South Korean rivers and estuaries, which occurred recently due to the changes in societal demands for water and explained how the most advanced scientific research techniques had been applied. The main issues were 1) agricultural water security and ecological environment restoration in Nakdong River Estuary, 2) water and soil quality degradation due to industrial effluents in Hyeongsan River Estuary, and 3) utilization of rivers as waterways and water quality and ecology issues in the ARA waterway. To find solutions to conflicts of water resources, the series of numerical simulations validated by the field observations allowed 1) assessments of the impact and extent of salt intrusion upon the opening of estuary dam gates, 2) estuarine physical processes to investigate the influence of industrial effluent, and 3) analysis water quality variations resulting from changes in the function of artificial channels. These analyses are expected to provide appropriate and science-based strategies of regional water management.

Published: March 2024

Abstract
Economic growth remains the sole determining factor that shapes regional development in Sukamara Regency, Kalimantan Tengah, Indonesia. Therefore, in designing and formulating its regional planning, it is imperative that the leading economic sector(s) be specifically studied and prioritized. Using quantitative data and regional analysis, this research aimed to identify the leading sector(s) to formulate recommendations for the regency’s development planning using geographic information systems and three economic growth indicators: location quotient (LQ), multiplier effect (ME), and shift-share (SS). Results indicate that Forestry, Agriculture, and Fisheries is the primary leading sector, followed by Manufacturing, which are both fuelled by the palm oil industry. The prevailing industrial sector causes economic disparities between northern and southern Sukamara. For further regional development, disparities between regions and sustainability issues must be addressed using a nature-based approach and socially inclusive measures by promoting and fostering small and medium enterprises, especially in southern Sukamara. Shifting the economy from extractive sectors (primary) to trade and tourism (secondary and tertiary) is also recommended to ensure the sustainabality of the development.

Published: March 2024

Abstract
Using quantum systems with more than two levels, or qudits, can scale the computational space of quantum processors more efficiently than using qubits, which may offer an easier physical implementation for larger Hilbert spaces. However, individual qudits may exhibit larger noise, and algorithms designed for qubits require to be recompiled to qudit algorithms for execution. In this work, we implemented a two-qubit emulator using a 4-level superconducting transmon qudit for variational quantum algorithm applications and analyzed its noise model. The major source of error for the variational algorithm was readout misclassification error and amplitude damping. To improve the accuracy of the results, we applied error-mitigation techniques to reduce the effects of the misclassification and qudit decay event. The final predicted energy value is within the range of chemical accuracy.
