Simulation studies for neutron and muon-induced backgrounds in AMoRE-II
Authors: Bae HW , Kim HJ , Kim YD , Jeon EJ , Lee MH 
Published: March 2020

Abstract
The Advanced Mo-based Rare process Experiment (AMoRE) is an experiment to search for neutrino-less double beta decays of Mo100. The second phase of the experiment, AMoRE-II, will be conducted with 200 kg of Mo100-containing crystals. To reach a sensitivity goal at 12-22 meV level in the effective neutrino mass, AMoRE-II is required to have no background at the region of interest. Dominant sources of backgrounds are expected from environmental neutrons, cosmic muons, and muon secondaries. In this study, we perform simulations of the backgrounds from cosmic muon and environmental neutrons with the Geant4 framework. Using those simulated background sources, we have examined the performance of muon veto counters, and shielding structures with polyethylene and additional materials containing hydrogen and boron. We found an optimal background estimation of ckky level of 10−5 order of magnitude with “the best choice of the setup” which would be acceptable for the AMoRE-II experiment requirement.

The SNOLAB underground laboratory
Authors: Hall J 
Published: March 2020

Abstract
The SNOLAB laboratory is 2 kilometers undeground in Sudbury, Ontario, Canada. The depth of this location results in a reduction of cosmic-radiation induced muons to the negligible level of one muon per square meter per day. The laboratory maintains cleanliness standards to control the radioactivity from dust falling out of the air, from human activity, and from research equipment brought into the lab. The resulting low-radiation environment enables a variety of research, and SNOLAB is focused on rare-event searches such as dark matter searches and nuclear decay studies. In order to enable and advance these research topics, SNOLAB is conducting research and development into cleanliness, low-level assay, radioactive gasses and cryogenics. SNOLAB collaborates, and competes, with other underground laboratories on these research and development topics, as well as operational topics, to support the global research community.

interactions in the water. Despite Gd powder’s high purification, some radio-isotope contaminates are expected. Among them 222Rn, from 226Ra decays, is a threat for high-precision low energy physics experiments like the Super-Kamiokande experiment (SK). The measurement of 222Rn from Gd-water is then needed in order to allow monitoring of its concentration in the water, as well as to test the efficiency of radio-isotope removal methods still in development. Here we present the system used to determine the 222Rn concentration from pure water and Gd-water. We also show the measurements of 222Rn (226Ra) concentration from water loaded with different Gd powders.
Radon monitoring in the Kamioka mine
Authors: Pronost Guillaume 
Published: March 2020

Abstract
Radioactivity from radon is one of the main backgrounds for low energy experiments, like Super-Kamiokande and the other experiments hosted in Kamioka Observatory. In addition, it is an issue for the safety of the researchers and technicians working in underground laboratories. In the Kamioka Observatory, a total of 29 1-L radon detectors are deployed in different areas in order to monitor the radon concentration and ensure it stays below a certain limit. Here we briefly describe the 1-L radon detector system and their Raspberry Pi-based data acquisition system. The evolution of the tunnel’s radon concentration over the last 3 years is then shown and discussed.
Geant4 based Simulation Study for Super-Kamiokande
Authors: Harada Masayuki 
Published: March 2020

Abstract
Super-Kamiokande (SK) will start a new phase “SK-Gd” from next year. Currently, SK uses Geant3 based simulation, however, its development has already stopped. For the next 10 years of SK-Gd operation, updated detector simulation is essential. For diffuse supernova neutrino background search in SK-Gd, precise neutron simulation is crucial. Therefore, we developed Geant4 based SK simulation software, named’ SKG4’ . Starting from the construction of SK geometry, some comparisons with the current SK detector simulation has been done. In this presentation, the current status of the development for SKG4 and the result of the several physics simulations will be reported.

Published: March 2020

Abstract
The topic of static and dynamic electricity is an abstract concept and relatively difficult for students to understand, especially in a case when the students were only taught about the electricity as a concept of electrical current, by means of the flow of electron, using analogy, without accompanied by practical experiments. This study aims to develop a lesson in the topic of dynamic electricity in an interesting and easy to understand approach using appropriate learning media that accompanied the abstract concepts with the real practical experiments. We used the equipment of ELVIS II+ (Engineering Laboratory Virtual Instrumentation Suite) from National Instruments to achieve the aforementioned goal. Props were designed to support various basic and advance dynamic electricity experiments. Selected topics relate to basic competencies 4.2 mandated by the ministerial regulation No. 24 in 2006 issued by the ministry of education and culture of the Republic of Indonesia (Permendikbud No. 24, 2016) exemplified by the capacitor charging and discharging experiments. It is expected that the activities would become interesting for the students since they were conducting the engineering process during the experiments that provided a fun learning. The more interesting part of the experiments was the understanding of concepts of science obtained from applying mathematics to solve differential equation problems. The application of mathematics appeared naturally when students constructing and solving the differential equations in order to understand the science behind the electrical phenomena. The most fascinating part for the students occurred when they can successfully proofed the solutions to differential equations with experimental results. Integrating the whole STEM (Sciences, Technology, Engineering, and Mathematics) components in the learning approach is proofed to be the key to the slogan of “learning is fun”. The experiment syntax followed the Investigation Sciences Learning Environment (ISLE) model so that the learning processes will develop thinking ability as prospective researchers in students.

Abstract
This study explored the use of comics in teaching secondary mathematics students the topic of ‘Order of Operations’. The focus was to improve students’ achievement with the use of comics as a tool to enhance the learning process and at the same time develop students’ interest in learning mathematics. A total of 33 Year 7 students from one of the secondary schools in Brunei Darussalam were involved in this study. Using an action research as the design research approach, two sets of comics relating to the concept of Order of Operations were used to teach students during the intervention lessons. A pre-test was given prior to the lessons, and then a post-test after the intervention lessons were completed. The results between the scores of the students’ pre- and post-tests showed improvements in their performance, indicating that the use of comics does help students in a way in learning the topic of the Order of Operations. Throughout the intervention sessions where comics were incorporated, students’ reactions to comics were taken into account through classroom observations as part of the analysing process. A few selected students were interviewed to give their feedbacks and their thoughts on using comics during lessons. While most had positive views towards comics in general with the majority stating that using comics made the lessons fun and interesting, there were also those who found comics not suitable to be used in the educational setting. The overall findings suggested that using comics have the potential to be used as a tool for teachers to facilitate their students’ learning.

Published: March 2020

Abstract
This study explores the use of comics in teaching elementary school students on solving Mathematics Word Problems. A total of 12 Year 2 students from an elementary school in Brunei Darussalam were chosen to participate in the study. A series of comics were created and some exercises included characters that were adapted from a local popular culture for utilization in teaching the students in order to engage their learning. The method chosen to conduct the research is of mix method adapted through usage of the action research model. A pre-test was conducted before the lesson intervention to assess the students’ prior knowledge of the content on the terms used in mathematics word problems. Subsequently a post-test was administered right after the intervention lessons were completed in order to discern if there were any significant improvements. Based on a classroom observation that was video recorded when the intervention was carried out, the children were highly motivated and very much interested in the content of the comics. Furthermore, the findings from the interviews revealed two major themes, which are ‘Enjoyment’ that detailed the students enjoying and had fun with the usage of the comics in the classroom, whereas ‘Interest’ tied in with the students’ enjoyment that resulted from their interest in the comic books. It is recommended that educators use comics in classroom due to its potential, especially in mathematics, where certain concepts can be quite challenging for some students to grasp.

Authors: Maulani S , Musthafa B , Agustin M 
Published: March 2020

AbstractThis study aims to design a model that is really needed by teachers in schools by taking four major steps. First, through the latest theoretical studies, we identified at least six models specifically developed by experts for the purpose of facilitating elementary school children in learning literacy. Second, those six models are then contrasted to see which main components are included in each model studied. Third, from the steps of comparing and contrasting of these learning models, a small number of mandatory components will be determined which basically represent three things: the role of the teacher, the task of the child, the support provided by the teacher. Fourth, the researchers made a prototype of a literacy learning model that is potentially suitable for elementary school students in early grades. This research is design-based research. The result of this research—in the form of the acronym of E2M-- will be provide wide space for teachers of elementary schools to facilitate children’s literacy development and fulfill children’s needs for their literacy learning.

Published: March 2020

Abstract
Currently, e-learning is suitable to be used as one of the learning models in Mathematics subject on High School or Vocational School level as an impact of the presence of the 4.0 industrial revolution. However, this e-learning model is not always effective to be used to obtain quality learning outcomes because it can only be used to measure cognitive domains. To obtain learning outcomes in the cognitive, affective, and psychomotor domains, so another learning model innovation is needed. One model that can be used is blended learning for Mathematics subject using the Kelase platform with material content that is packaged based on the Tri Kaya Parisudha concept. The Kelase platform is used to create blended learning facilities that contain features needed to accommodate material content. The Tri Kaya Parisudha concept, which consists of manacika, wacika, and kayika, is used as the basic foundation for making material content that can measure cognitive, affective, and psychomotor domains. Based on those statements, the purpose of this study was to find out the general description of the initial design of blended learning for Mathematics subject (especially at the high school or vocational school level) that was created using the Kelase platform with material content based on Tri Kaya Parisudha. The method used in this study was R&D with the Borg and Gall model, which focuses on the stages of design development. The subjects involved in designing this blended learning were three people. The tools used to make blended learning designs, such as Kelase platform and Balsamiq Mockups. The results obtained in this study were the formation of an initial design of blended learning that created used Kelase platform by presenting facilities that could be used to fill Tri Kaya Parisudha-based Mathematics content.
