STEM-based learning systems have become commonplace in developed countries today. Students who are taught STEM are expected to be able to realize their imagination and creativity from an early age by directly implementing the basic knowledge gained during school into a real product so that the level of students' understanding of a science can be deep and lasting. Early habituation for schoolage students to get acquainted and plunge into direct practice related to STEM is their main capital in facing future challenges that require adaptation to many new things and a race for creativity that is able to produce innovative products of commercial value and be utilized by mankind. The product resulting from this study received a very positive response from several students who were respondents, although of course, improvements were still needed in terms of the hardware and software that were built.
如今,基于stem的学习系统在发达国家已经司空见惯。通过将在学校所学的基础知识直接应用到实际产品中,期望STEM教育的学生从小就能发挥他们的想象力和创造力,从而使学生对一门科学的理解水平能够深入而持久。学龄学生的早期习惯是了解并投入到与STEM相关的直接实践中,这是他们面对未来挑战的主要资本,这些挑战需要适应许多新事物,以及能够产生具有商业价值并为人类所利用的创新产品的创造力竞赛。从这项研究中产生的产品得到了一些学生的非常积极的回应,尽管当然,在硬件和软件方面仍然需要改进。

Experiments on nuclear physics with precise measurements are exciting things to do. The experiment supports the STEM approach based on real experiments and especially if it is low-cost equipment. In this study, a preliminary study was conducted on the proton precession magnetometer (PPM) design, which will be used as a teaching aid for STEM learning to explore the atomic nucleus and as a magnetometer to determine the strength of the earth's magnetic field accurately. The PPM signal is susceptible to changes in the external magnetic field so that external magnetic disturbances such as electric currents and ferromagnetic materials in the building produce noise. So the measurements are carried out outside the building. The sensor uses two coils that are polarized opposite each other to eliminate the noise from the outside. In addition, analog filtering is also designed in a bandpass filter only to pass the desired frequency range. Since the PPM signal is tiny, the coil is coupled with a suitable capacitor to amplify the signal radiated by the protons through an inductor-capacitor resonance effect at the desired target frequency. Signal PPM measurement results in the time domain can be displayed, although visually, it is difficult to recognize because it is immersed in noise. However, when heard with the human ear, the distinctive sound of the PPM signal will be clear for about 3 seconds after applying polarizing current to the coil. Waves in the time domain can be converted into the frequency domain using audacity 3.0.2 software. The peak frequency obtained is 1914 Hz. Based on the values of these frequencies, based on the Larmor formula, the value of the earth's magnetic field obtained is 44.97 uT.
具有精确测量的核物理实验是令人兴奋的事情。该实验支持基于真实实验的STEM方法,特别是如果它是低成本的设备。本研究对质子进动磁强计(PPM)的设计进行了初步研究,该设计将作为STEM学习的教具来探索原子核,并作为磁强计来精确测定地球磁场的强度。PPM信号易受外部磁场变化的影响,使建筑物内的电流、铁磁性材料等外部磁干扰产生噪声。所以测量是在大楼外进行的。该传感器使用两个相互极化的线圈来消除来自外部的噪声。此外,还在带通滤波器中设计了模拟滤波,仅使其通过所需的频率范围。由于PPM信号很小,线圈与合适的电容器耦合,通过电感-电容器谐振效应在期望的目标频率上放大质子辐射的信号。信号PPM在时域内的测量结果虽然可以直观地显示出来,但由于沉浸在噪声中,难以识别。然而,当用人耳听到时,在对线圈施加极化电流后,PPM信号的独特声音将清晰约3秒。使用audacity 3.0.2软件可以将时域的波转换为频域。得到的峰值频率为1914 Hz。根据这些频率的值,根据拉莫尔公式,得到地球磁场的值为44.97 uT。

School closure during the pandemic requires teachers to integrate digital technology for teaching and learning. Therefore, it is necessary to examine mathematics teachers' digital literacy. The purpose of this study was to examine Indonesian secondary school teachers' digital literacy and investigate if digital literacy levels are significantly different in terms of gender, teaching experience, the level of schools, and teacher level of education. We conducted a quantitative study with a cross-sectional survey design. Data were collected from 232 secondary school teachers and analyzed by ANOVA. This study suggests that, to some extent, demographic variables do not play a significant role in teachers' level of teachers' digital literacy. It was found that, among demographic background variables examined in this study, only teachers' levels of education have a significant role in the level of digital literacy. It indicates that researchers and practitioners should take teachers' education level into account when they design and implement professional development on digital literacy.
大流行期间学校关闭要求教师将数字技术用于教学和学习。因此,有必要对数学教师的数字素养进行考察。本研究的目的是考察印尼中学教师的数字素养,并调查数字素养水平是否在性别、教学经验、学校水平和教师教育水平方面存在显著差异。我们采用横断面调查设计进行了定量研究。对232名中学教师进行问卷调查,采用方差分析方法进行分析。本研究表明,在一定程度上,人口统计变量对教师数字素养水平的影响并不显著。研究发现,在本研究考察的人口统计背景变量中,只有教师的教育水平对数字素养水平有显著影响。这表明研究者和实践者在设计和实施数字素养专业发展时应考虑教师的教育水平。

2D resistivity models of magnetotelluric data had been simulated for studying magma activity within volcanic conduits. The simulated models can be used to understand the pre-eruption of volcanic behavior based on the change of resistivity responses measured on an active volcano. Four resistivity models of conduit states have been modeled using REBOCC MT forward modeling code. The models include a conduit with empty magma, the magma starts to accumulate in the conduit, the magma rises, and the conduit full of magma. The resistivity value of the empty conduit and the magma material was 10 Ohm-m and 50.000 Ohm-m, respectively. While the conduit is located within a volcano composed of three resistivity layers, i.e., 100 Ohm-m, 400 Ohm-m, and 1000 Ohm-m from the top to the bottom. The synthetic data responses generated by each model were used to analyze each state. The calculated transfer function of magnetotelluric data includes apparent resistivity and phase for TE-mode. Each data set were calculated in range of period 0.001, 0.01, 0.1, 10, 100, 1000 s. The results showed that apparent resistivity responses increase with increasing the magma height in the conduit. The simulated models can be used to predict the height of the magma before it would be reached the surface as a precursor of a volcanic eruption.
为研究火山导管内岩浆活动,对大地电磁资料的二维电阻率模型进行了模拟。模拟模型可以根据在活火山上测量到的电阻率响应的变化来了解火山喷发前的行为。利用REBOCC MT正演模拟程序对管道状态的4种电阻率模型进行了模拟。这些模型包括一个有空岩浆的管道,岩浆开始在管道中积聚,岩浆上升,以及充满岩浆的管道。空导管的电阻率为10 ω -m,岩浆物质的电阻率为5 ω -m。而管道位于火山内,火山由三个电阻率层组成,从上到下分别为100欧姆、400欧姆和1000欧姆。每个模型生成的综合数据响应用于分析每个状态。计算的大地电磁资料传递函数包括te模式下的视电阻率和相位。每个数据集在0.001、0.01、0.1、10、100、1000 s的范围内进行计算。结果表明,视电阻率响应随岩浆高度的增加而增大。模拟的模型可以用来预测岩浆到达地表之前的高度,作为火山爆发的前兆。

The 21st century has witnessed extraordinary improvement on educational technique technologically known as E-learning. Google Classroom has officially been introduced to Malaysian schools in 2019 and all teachers have been given a training regarding this platform usage since then. Yet, very petite is known about STEM teachers' acceptance of this facility. The objective of this study is to propose an improved conceptual framework of modified UTAUT2 by introducing three new constructs namely, Self-Efficacy (SE), Trust (T) and Personal Innovativeness (PI) towards E-Learning acceptance. However, this study is mainly based on an in-depth recent literature review derived from Scopus database.

Evaluation of the automated testing kit used to assess a person's psychomotor skill experience has become crucial in an era that was very concerned with practical skills, especially in the engineering field. Furthermore, current testing kits need a better upgrade to access the advanced skills of individuals who use them. Therefore, a new study to improve the existing test kits with unique features better than the original testing kit. This study aims to create a new approach to test a practical experience change to assess unintentional learning related to classic psychomotor skills in engineering technology laboratory classes. The methodology used to build up the instrument is portrayed, and the empirical data collected to support its validity is presented. The testing kit's expected results to improve measuring practical skills involved in a psychomotor change in engineering laboratory classes is proven.
在一个非常关注实用技能的时代,尤其是在工程领域,对用于评估一个人的精神运动技能经验的自动化测试工具的评估变得至关重要。此外,目前的检测试剂盒需要更好的升级,以获得使用它们的个人的高级技能。因此,一项新的研究使现有的检测试剂盒具有比原有检测试剂盒更好的独特功能。本研究旨在建立一种新的方法来测试实践经验变化,以评估工程技术实验课中与经典精神运动技能相关的无意识学习。本文描述了构建该工具的方法,并给出了收集到的支持其有效性的经验数据。该测试套件的预期结果,以提高测量实际技能,涉及精神运动的变化,工程实验课被证明。

This paper focuses on the state of readiness of Indonesian higher education to integrate online courses, particularly during study from home as a result of the COVID-19 pandemic. The case study was carried out at the University of Lampung (Unila), one of the state universities of Indonesia. The result shows the rapid increase in the number of visitors to Unila's learning management system during the beginning of studies from home regulations. The Aydin and Tasci E-learning Readiness (ELR) method is used to assess Unila's readiness to implement the online course. The study is also important to show the Unila readiness to support Merdeka Belajar regulation issued by the Ministry of Education and Culture (MOEC) of Indonesia. The result shows that the average ELR score is 4.43. This result indicates that Unila is in a state of readiness for the implementation of e-learning, and the application of e-learning can be continued. However, several things can be improved, especially with regard to ELR factors which have lower scores.
本文重点关注印度尼西亚高等教育整合在线课程的准备状况,特别是在2019冠状病毒病大流行期间在家学习期间。这项个案研究是在印度尼西亚国立大学之一的楠榜大学(乌尼拉)进行的。结果显示,在开始在家学习期间,访问Unila学习管理系统的人数迅速增加。使用Aydin和Tasci在线学习准备(ELR)方法来评估Unila实施在线课程的准备情况。这项研究也很重要,因为它表明Unila愿意支持印尼教育和文化部(MOEC)发布的Merdeka Belajar条例。结果表明,平均ELR得分为4.43。这一结果表明,Unila处于实施e-learning的准备状态,可以继续进行e-learning的应用。然而,有几件事可以改进,特别是关于ELR因素,得分较低。
