Mathematical physics has been known as a complex subject for most students to understand. The Islamic values-oriented mathematical physics module was developed to support students learning independently and help them improve intellectually and spiritually in mathematical physics courses. This research aimed to determine the Islamic values-oriented mathematical physics module's development process, validity, and practicality. This research is R&D based on the 4D model, which consists of four steps, namely define (needs analysis and curriculum review), design (module design), develop (module validation with material, media, and tafsir expert validators), and disseminate (student and lecturer responses test). Two aspects related to the developed module are identified: validity and practicality. The validity aspect is obtained from the assessment results by expert validators. Meanwhile, the practicality aspect was obtained from the responses from the lecturers and students who took the mathematical physics course. The novelty of the research is integrating Islamic values into the mathematical physics module so students can improve intellectual and spiritual aspects. The results of the assessment by the expert validator show that the Islamic-values-oriented mathematical physics module is valid and practical to use, with a percentage of assessment by material experts of 94% (excellent), assessment by media experts of 92% (very valid), and assessment by tafsir experts 97% (perfect). Meanwhile, the students' evaluation of the practicality of the module was 96% (efficient), and the evaluation by the lecturers was 97% (efficient). Further researchers are advised to develop research results by involving more research subjects with physics education students from other universities.
众所周知,对于大多数学生来说,数学物理是一门复杂的学科。伊斯兰价值观导向数学物理模块的开发旨在支持学生自主学习,帮助他们在数学物理课程中提高智力和精神水平。本研究旨在确定以伊斯兰价值观为导向的数学物理模块的开发过程、有效性和实用性。本研究基于 4D 模型进行研发,该模型由四个步骤组成,即定义(需求分析和课程审查)、设计(模块设计)、开发(由材料、媒体和塔夫西尔专家验证员对模块进行验证)和传播(学生和讲师反应测试)。与开发的模块有关的两个方面是:有效性和实用性。有效性来自专家鉴定人的评估结果。同时,实用性方面的信息来自数学物理课程讲师和学生的反馈。该研究的新颖之处在于将伊斯兰价值观融入数学物理模块,从而提高学生的智力和精神水平。专家鉴定人的评估结果表明,以伊斯兰价值观为导向的数学物理模块具有有效性和实用性,材料专家的评估比例为 94%(优秀),媒体专家的评估比例为 92%(非常有效),塔夫西尔专家的评估比例为 97%(完美)。同时,学生对该模块实用性的评价为 96%(有效),讲师的评价为 97%(有效)。建议研究人员与其他大学的物理教育专业学生一起参与更多的研究课题,进一步开发研究成果。

This study aims to (1) Analyze the application used for making animated test questions. (2) Analyzing the use of animated test questions based on education level. (3) Analyzing the use of animated format test questions based on physics learning materials. (4) Analyzing the use of animated test questions on students' understanding of physics concepts. This study uses a systematic review method using 16 national and international journal articles from 2010-2022. The results of this study showed that: (1) The application used to make test questions in animation format is very large, but Macromedia Flash is more often used. (2) Animation test questions are widely applied or used at the Senior High School level. (3) For material in physics learning, animated test questions are more often applied to the concept of light refraction. (4) Animation test questions can help students to improve their understanding of concepts. The study results show that the animated format test questions affect students' conceptual understanding. However, in reality, when carrying out the test, the format of the questions presented is still in the form of a paper, and a test is in the form of an arguments. Teachers do not know how the influence of the use of animated test questions on students' understanding of concepts, as well as what applications can be used in making animated test questions

Education is one of the most affected areas by the Covid-19 pandemic, especially learning. This learning is new in the PGSD Study Program at FKIP Mataram University, so monitoring and evaluation are needed. This research aims to describe the process and students' learning outcomes through the implementation of SPADA Unram and the Natural Laboratory. The research sample comprised 63 students who took Basic Natural Sciences or Ilmu Alamiah Dasar (IAD) courses—data collected for eight weeks in October–December. Data about activity and student learning outcomes include (1) the activeness in discussion forums, (2) the discipline in collecting assignments, (3) the skills in completing assignments, and (4) the ability to complete quizzes. Descriptive statistics analyzed data to determine the mean and proportion. Only a tiny proportion (<50%) of students participated in discussion forums. From the disciplinary aspect, the balance of disciplined students is the largest, but many are still not disciplined in uploading assignments at SPADA Unram. Students' skills in completing tasks are excellent, but their ability to complete quizzes is in the fair category. Indicates that improvements are needed to maintain and improve the quality of science learning processes and outcomes during the pandemic.
教育是受 Covid-19 大流行病影响最严重的领域之一,尤其是学习。在马打兰大学的 PGSD 学习课程中,这种学习是一种新的学习方式,因此需要进行监测和评估。本研究旨在描述通过实施 SPADA Unram 和自然实验室的过程和学生的学习成果。研究样本包括 63 名选修基础自然科学或 Ilmu Alamiah Dasar (IAD) 课程的学生,数据收集时间为 10 月至 12 月的 8 周。有关活动和学生学习成果的数据包括:(1)论坛讨论的积极性;(2)收集作业的纪律性;(3)完成作业的技能;以及(4)完成测验的能力。描述性统计对数据进行了分析,以确定平均值和比例。只有很小一部分学生(<50%)参加了讨论论坛。从纪律方面来看,遵守纪律的学生所占比例最大,但仍有许多学生在 SPADA Unram 上传作业时不遵守纪律。学生完成任务的能力很好,但完成测验的能力属于一般。表明需要改进,以保持和提高大流行病期间科学学习过程和结果的质量。

Research on hemp fiber composites with epoxy resin matrix and lead acetate as an alternative material for X-ray radiation shielding has been conducted to determine the optimal composition of radiation shielding samples made from hemp fiber, epoxy resin, and lead acetate. The method used to make composite samples with six different designs, namely using a ratio of 4 gams, eight gams, and 12 gams of hemp fiber to 80 gams and 160 gams of resin. The lead acetate used in each composition is 2.5 gams. This study carried out three measurement processes: density, attenuation, and absorption. Density measurements were carried out by measuring the volume and mass of the sample. In contrast, attenuation and absorption measurements were carried out using a mobile X-ray aircraft with a Piranha multi-X-ray meter detector. In the three measures, the highest value was obtained in composition VI, namely with 12 gams of hemp fiber, 160 gams of epoxy resin, 80 gams of catalyst, and 2.5 gams of lead astate. The density value obtained was 1.120 g/cm3. The sample with this composition can absorb 71.22% (1.24580 cm-1) of radiation at 40 kV, absorb 66.91% (1.10621 cm-1) at 60 kV and 60.22% (0.92191 cm-1) of radiation absorbed at 81 kV voltage. Therefore, it can be concluded that the higher resin and hemp used, the more excellent density value obtained—the geater density of the sample, the geater value of attenuation and absorption.
以环氧树脂为基体,以醋酸铅为替代材料的大麻纤维复合材料进行x射线辐射屏蔽研究,确定以大麻纤维、环氧树脂、醋酸铅为基体的最佳辐射屏蔽样品组成。该方法使用6种不同设计制作复合样品,即使用4克、8克和12克大麻纤维与80克和160克树脂的比例。每种成分中使用的醋酸铅是2.5克。本研究进行了密度、衰减和吸收三个测量过程。密度测量是通过测量样品的体积和质量来进行的。相比之下,衰减和吸收测量是使用带有食人鱼多x射线计探测器的移动x射线飞机进行的。在三个测量中,组合物VI的值最高,即大麻纤维12克,环氧树脂160克,催化剂80克,铅酸盐2.5克。所得密度值为1.120 g/cm3。该成分样品在40 kV时吸收71.22% (1.24580 cm-1),在60 kV时吸收66.91% (1.10621 cm-1),在81 kV时吸收60.22% (0.92191 cm-1)。因此,可以得出结论,树脂和大麻用量越高,获得的密度值越优异,样品的密度越大,衰减和吸收值也越大。

This paper focuses on the characteristics of K0.5Na0.5VO3 (KNV) and SiO2 when added to Mg0.8Zn0.2TiO3 (MZT) material to reduce the sintering temperature. Initially, a single phase of Mg0.8Zn0.2TiO3 (MZT) was synthesized using the conventional solid-state reaction method at 850°C for 4 hours. Subsequently, (K0.5Na0.5)VO3 was formed as a single phase at a temperature of 500°C for 2 hours. The reduction of MZT sintering temperature was then carried out by adding K0.5Na0.5VO3 and SiO2 and sintering at 950°C for 4 hours. Adding K0.5Na0.5VO3 and SiO2 resulted in a maximum density value of 2.76 g/cc and an average grain size of 3 µm based on scanning electron microscopy (SEM) analysis. The optimal composition was found to be 0.7MZT-0.25KNV-0.05SiO2. X-ray diffraction (XRD) characterization using the Rietveld method revealed the presence of three phases: (Mg/Zn)TiO3, (K/Na)VO3, and MgTi2O5. Based on the results, it can be concluded that the (K/Na)VO3-SiO2 material can be effectively utilized as a sintering agent for (Mg/Zn)TiO3, reducing the sintering temperature of the material.
本文重点研究了在Mg0.8Zn0.2TiO3 (MZT)材料中加入K0.5Na0.5VO3 (KNV)和SiO2以降低烧结温度的特性。首先,采用常规固相法在850℃下反应4小时,合成了Mg0.8Zn0.2TiO3 (MZT)单相。随后,(K0.5Na0.5)VO3在500℃的温度下形成单相。通过添加K0.5Na0.5VO3和SiO2,在950℃下烧结4小时,降低MZT烧结温度。扫描电镜(SEM)分析显示,添加K0.5Na0.5VO3和SiO2后,样品的密度最大为2.76 g/cc,平均晶粒尺寸为3µm。最佳配比为0.7MZT-0.25KNV-0.05SiO2。采用Rietveld方法进行x射线衍射(XRD)表征,发现存在(Mg/Zn)TiO3、(K/Na)VO3和MgTi2O5三个相。综上所述,(K/Na)VO3-SiO2材料可以有效地作为(Mg/Zn)TiO3的烧结剂,降低材料的烧结温度。

The purpose of this study was to compare the application of the think pair share (TPS) learning method and conventional methods to student learning outcomes in physics learning. The type of research used is quasi-experimental (Quasy Experimental Design). The subjects in this study were two classes, namely 24 X MIPA 1 students as an experimental class using the Think Pair Share (TPS) learning method and 24 X MIPA 2 students as a control class using conventional methods. The sampling technique used purposive sampling. Data collection techniques using documentation, tests, and observations. The data analysis technique used in this study was the Independent Sample Test (t-test) with a significance level of 5%. Before the data were analyzed, a prerequisite test for normality analysis was carried out. The results showed that there were differences in the learning outcomes of students who were taught using the TPS method with conventional methods in physics subjects. Where the average post-test score for the experimental class was 72.45, higher than the control class, which was 51.54. These results indicate that student learning outcomes in the experimental class experienced a significant increase compared to the control class. The results of calculating the gain score for the experimental class obtained an average pre-test of 54.04 and a post-test of 72.45 so a Gain of 0.40 was obtained in the moderate category. Whereas in the control class, the average pre-test was 49.87 and the post-test was 51.54 so a gain of 0.03 was obtained in the low category. This shows that learning using the TPS method is better than using conventional methods.
