This study aims to analyze the influence of TPACK variables on junior high school teachers in Pasar Jambi District. The type of research used is quantitative research with a survey approach via ...WhatsApp groups and filling out questionnaires via google forms. The data collection technique used a questionnaire and then analyzed using the Structural Equation Model-Partial Least Square (SEM-PLS) method with SmartPLS software. From the results of the analysis, there are 5 out of 12 variable relationships that have a significant effect. Seven variables do not have a considerable impact: CK variables on TCK, CK on TPACK, PCK variables on TPACK, PK variables on PCK, PK variables on TPACK, PK variables to TPK, and TPK variable to TPACK. This shows that pedagogical and content knowledge does not significantly influence the teacher's TPACK ability. This research is expected to improve teacher TPACK competence, especially in technological knowledge, because teacher TPACK abilities are strongly influenced by technological knowledge.
The interesting learning media will help students to understand physics. Comic is one of the alternative learning media that can be used in the learning process. The using of comic has been used ...widely in the field of education. This research aimed to develop a work and energy comic based on Jambi folklore, Aminuddin and Aminullah, for senior high school students. The scenes of comic will be connected to the concepts of physics especially on the work and energy concepts. This study used research and development method referring to the ADDIE model which consisted 5 stages : Analyze, Design, Development, Implementation and Evaluate. The results of the students response and expert validation of comic showed that the comic is feasible to use in learning.
Conceptual understanding is one of the important things in physics learning. Many factors affected the conceptual understanding of students; one of them was the book. Based on the data from the ...implementation of a questionnaire on junior high school students, their learning resources (books, etc.) have not been able to help them understand many concepts of physics including the concepts of electrostatics.Some abstract concepts in physics make them more difficult to understand physics. This study aimed to develop electrostatic teaching material-oriented to conceptual understanding for junior high school students. We use the ADDIE model, i.e., analyze, design, development, implementation, and evaluation. The result of this study shows that the teaching material is feasible to use in learning based on the feedback from validators.
The mass–action equivalence emerges naturally as the consequence of Relativistic Heisenberg Uncertainty (RHU). It changes the structure of relativistic energy–momentum equation that has been ...underpinning the chosen Lagrangian of the Standard Model, i.e., the Lagrangian which the Higgs mechanism works. The transition from the mass–energy to the mass–action equivalence zone occurs at a certain value of the particle’s wave group velocity
v
g
indicating the crossing curve between relativistic energy and action. Due to this transition, particles in the Standard Model are not going to gain inertial mass coming from the Higgs mechanism and related Higgs field, but from another mechanism which can break the Lagrangian symmetry of the Standard Model. This mechanism corresponds to Explicit Symmetry Breaking by generating the new type of field, i.e., the
X-Higgs
-like field and works based on the mass–action equivalence. This field provides the mass for the
X
Matter as well as Higgs field for Ordinary Matter. The gaining mass of particles due to this mechanism is not related to the form of ordinary relativistic energy, but to the form of relativistic action. It leads us to the new dynamical equation instead of the ordinary Klein–Gordon and Dirac equation. There are two phenomena due to the increasing and decreasing of particle’s velocity in this mechanism. From the lower to the higher velocity, particle gains additional inertial mass from the
X
Matter, while conversely particle loses its inertial mass. It is reasonable for us to view that the missing inertial mass of particles in the Standard Model is compensated as the Dark Matter. The
X-Higgs
-like field breaking to be the Dark-Higgs-like and recognized Higgs field can be considered to explain the origin of the Dark and Ordinary Matter from the
X
Matter.
Masalah yang sering ditemui pada pembelajaran di sekolah khususnya mata pelajaran fisika yaitu banyaknya peserta didik yang menyatakan mata pelajaran fisika sulit dipahami dan kurang tertarik dengan ...mata pelajaran fisika, hal ini disebabkan belum optimalnya media pembelajaran yang digunakan oleh guru sehingga menyebabkan peserta didik kurang memahami konsep dan tidak tertarik dengan pelajaran fisika. kurangnya ketertarikan tersebut dapat diatasi dengan video, sehingga diperlukan video pembelajaran yang dapat meningkatkan pemahaman konsep dan minat belajar peserta didik.

Distributed Denial of Services (DDoS) is still considered the main availability problem in computer networks. Developing a programmable Intrusion Prevention System (IPS) application in a Software ...Defined Network (SDN) may solve the specified problem. However, the deployment of centralized logic control can create a single point of failure on the network. This paper proposed the integration of Honeypot Sensor (Suricata) on the SDN environment, namely the SD-Honeypot network, to resolve the DDoS attack using a machine learning approach. The application employed several algorithms (Support Vector Machine (SVM), Multilayer Perceptron (MLP), Gaussian Naive Bayes (GNB), K-Nearest Neighbors (KNN), Classification and Regression Trees (CART), and Random Forest (RF)) and comparatively analyzed. The dataset used during the emulation utilized the extracted Internet Control Message Protocol (ICMP) flood data from the Suricata sensor. In order to measure the effectiveness of detection and mitigation modules, several variables were examined, namely, accuracy, precision, recall, and the promptness of the flow mitigation installation process. The Honeypot server transmitted the flow rule modification message for blocking the attack using the Representational State Transfer Application Programming Interface (REST API). The experiment results showed the effectiveness of CART algorithm for detecting and resolving the intrusion. Despite the accuracy score pointed at 69-70%, the algorithm could promptly deploy the mitigation flow within 31-49ms compared to the SVM, which produced 93-94% accuracy, but the flow installation required 112-305ms. The developed CART module can be considered a solution to prevent the attack effectively based on the analyzed variable.
Relativistic Heisenberg Uncertainty relation (RHU), i.e. ΔpΔx≥ℏ/21-v2c2-1 has been built as the different version of the relation which corresponds to the Generalized Uncertainty Principle (GUP), ...i.e. ΔpΔx≥ℏ/21+βΔp2+⋯. This version of uncertainty relation is the function of average (group) velocity such a way that it causes the magnification of the phase space’s minimum limit in the relativistic domain. At the certain average velocity, this phenomenon will change our point of view from the conservation of energy to that of action spontaneously and gives the impact to the mass. Based on the action conservation, we need the concept of mass-action equivalence instead of the mass-energy equivalence to explain the missing or getting mass of the particle.
