  • Completely Prime Modules for Graded Simple Modules Which is Simple Over
           Leavitt Path Algebra

    • Authors: Risnawita Risnawita, Zubaidah Zubaidah
      Pages: 1 - 5
      Abstract: We characterize a graded simple module  in the setting Leavitt path algebras L which is the completely prime module. Let m  M  and r  A, an A-module M is called a completely prime module if    for one m  M  and r  A then 0  or m = 0. In this article, we show that If u is a sink or an infinite emitter, then a graded simple module which is simple  is not a completely prime module.

  • Prospective Biology Teachers’ View towards Theory of Evolution: A Case
           Study at Islamic University in Indonesia

    • Authors: M Haviz
      Pages: 6 - 19
      Abstract: This study was to investigate prospective biology teachers' views towards the theory of evolution at Islamic university. This study was concerned to investigate the quality of the instruments, the profile of literacy, attitudes, and religiosity of PBTs-IU, and the relationship between literacy and attitude towards the theory of evolution with religiosity. An explanatory mixed method was conducted by using a quantitative survey and in-depth interviews. A total of 153 (16 males and 137 females) from 185 prospective biology teachers at Islamic University (PBTs-IU) participated in filling out the questionnaire. Confirmatory factor analysis and Cronbach's alpha tests have been conducted to examine the quality of the instrument. PBTs-IU profiles were analyzed by descriptive statistical test, and a correlation test was used to determine the relationship between variables. Furthermore, triangulation was chosen to analyze the results of the interviews. The results of this study showed that the instruments used are valid and reliable, the profile of literacy, attitudes, and religiosity of PBTs-IU was high level, and there was a positive and significant relationship at the 0.01 and 0.05 levels between literacy and religiosity and attitudes and religiosity. These findings concluded that PBTs-IU have good knowledge of the theory of evolution, and PBTs-IU also have strong religious beliefs.

  • Simple and Multi Risk Assessment Framework for Information Security using
           Process Flow Diagram

    • Authors: Edri Yunizal, Judhi Santoso, Kridanto Surendro
      Pages: 20 - 35
      Abstract: Organizations need a simple risk assessment framework to understand them. In contrast, risk analysis requires some mathematical tools to be able to estimate risk based on understanding and availability. In practice, the assets, for which the risk will be calculated, are dependent on one another, resulting in inevitable complexity. We propose a framework that addresses these three situations with a process flow diagram. Simplicity is obtained from a conceptual model based on data flow diagrams which are widely used in information system design. This conceptual model can be translated into several risk models at once: graph, Boolean algebra, Boole’s algebra, and set theory. The complexity of asset dependencies is overcome when translating the conceptual model to the risk model. Solutions were shown in case studies of information systems for COVID-19 personal protective equipment in Indonesia, which require the construction of a simple information system, support multiple risk models, and take into account asset dependencies. The multi-risk model enables implementation proofing by testing the risk models used in each other.

  • Motivation to Learn Mathematics on Different Personality Types

    • Authors: Annisa Dwi Kurniawati, Tunjung Genarsih, Maulida Nurhidayati
      Pages: 36 - 43
      Abstract: Motivation is one of the aspects that support a person's learning success. A person's motivation level is very likely to differ from one to another. There are differences in learners' characteristics in the classroom learning process. One characteristic difference students process is the difference in personality types, in this case, introvert-extroverted. It is likely to impact a person's learning success. However, research that discusses this still needs to be completed. This study aims to know how high the motivation of mathematics education students who have an introverted personality type, how high the mathematics motivation of mathematics education students who have an extroverted personality is, whether there is a difference in mathematics motivation of mathematics education students based on personality type and whether there is a relationship between mathematical motivation and personality type. A quantitative research design with a purposive random sampling technique in 81 students was used in this study. The data analysis techniques are descriptive statistical data analysis, independent sample t-test, and Pearson correlation with the help of the SPSS 25 program. The results showed that: the motivation of introverted students on high criteria; the motivation of extroverted students on high criteria; there are differences in motivation based on introverted-extroverted personality types; and there is a significant relationship between mathematical motivation and introverted-extroverted personality types. It has implications for lecturers to anticipate problems that potentially arise and play a role in increasing student motivation related to their personality in the teaching and learning process.

  • Enhancing Conceptual Understanding and Concept Acquisition of
           Gravitational Force through Guided Inquiry Utilizing PhET Simulation

    • Authors: Ogi Danika Pranata
      Pages: 44 - 52
      Abstract: The concepts of gravity and orbits are difficult to visualize and understand. Computer simulations offer significant advantages for designing learning environments that address these difficulties. One of the best and most popular computer simulations is Physics Education Technology (PhET), which help student with simulation during inquiry-based learning. A quantitative method with the pre-and post-test design was applied to explore student conceptual understanding and concept acquisition about gravity and orbits. The study population consisted of 35 students taking basic physics courses, which was small enough that the entire population was used. A worksheet was designed based on simulation and concepts, with minimum guidance from a teacher. Conceptual understanding data was collected through three stages of testing: pre-test before learning, formative tests just after guided inquiry-based learning, and post-test at the end. The data from all the tests were analyzed descriptively to provide an overview of students’ conceptual understanding. N-Gain was also calculated. Then the condition in which students’ concept acquisition was categorized as loss, hold, and increase was measured. The average pre-test score was very low (32.26), but it increased significantly in the formative test (74.27) and post-test (74.73). The N-Gain values varied significantly among students, with an average categorized as medium (0.63). There were 18 students with high N-Gain, 8 students with medium N-Gain, and 5 students with low N-Gain. Based on formative and post-test data, we concluded that both gain and loss can occur in learning. Concept acquisition can give us more information about conceptual understanding.

           Science Process Skills for Physics Students

    • Authors: Pipi Deswita, Muharmen Suari, Adelia Alfama Zamista
      Pages: 53 - 60
      Abstract: This research aims to develop practicum modules based on science process skills. Science process skills are an approach to learning that is designed so that students can find facts and build concepts and theories. In this science process skill, students are trained to be involved in scientific activities and become independent individuals. The development model in this study is the 4D model. The research subjects were 39 third-semester students who had taken the course on electrical measuring instruments. The instruments in this study were validation sheets (to determine product validity) and student and lecturer response questionnaire sheets (to measure product practicability). The results showed that the product, in the form of a practicum module based on Science Process Skills, was both valid and practical. The module validity was in the very valid category, with an average score of 83.14%. The practicality test for using modules for students was very practical (83.3%). The lecturer response questionnaire was in the very practical category, with a percentage of 81.25%. So, this practicum module is valid and practical and can be used to train students' Science Process Skills, especially in the material of electrical measuring instruments.

      Pages: 61 - 68
      Abstract: Learning resources in the form of teaching materials that are interesting, innovative, communicative, contextual, and technology-based is a demand for public learning now. In line with the West Sumatra Regional Government program in integrating Al-Qur'an education in subjects in Senior High School, especially physics subjects, it is also something that must be included in the teaching materials. Even though there are many teaching materials and technology-based electronics that have been created, printed teaching materials remain the choice for the convenience of students in the study. Therefore, a physics module based on augmented reality integrated verses of the Qur'an on electricity is developed. The purpose of this study is to find out the validity and practicality of the module. This research is development research (R&D) using a 4D model (Define, Design, Develop, and Disseminate). This research is up to develop stage (validity and practicality). The results of the study indicate that the teaching material in the form of integrated augmented reality-based modules of electricity is very valid.  This result is according to four experts in terms of the feasibility of content, presentation, language, and graphics. The average score for the module is 90.09%. This module then tested 18 students in grade XII and the physics teacher of Raudatul Jannah Islamic School to gain the practicality aspect.  The result was 85.48% (students) and 90.90% (teachers), which are very practical. In conclusion, the module was very valid criteria according to the expert and was very practical based on the questionnaire filled out by students and teachers.
