This study aimed to determining the influence of students in understanding the concept of learning science in the classroom. The research subjects were students of class VIII at SMPN 3 Selong, namely class VIII A and class VIII B, with the data retrieval process using a written test of 5 items of description. The average value obtained in the control class is 65.48 while the experimental class is 85.48 with a difference of 20 points. For the hypothesis value t_hitung = 2.042 while t_tabel = 1.079 from the results of the calculation of the hypothesis test results of learning science students obtained t_hitung > t_tabel =, then the hypothesis alternative (Ha) is accepted. So it can be concluded that there is an influence in the application of the Problem Base Learning model in science learning at SMP 3 Selong

The title of this paper is Fraunhofer diffraction simulation using spreadsheet and GNU octave media as an alternative for learning during the pandemic. This paper aims to present an alternative to distance learning during the COVID-19 pandemic by using simulations using spreadsheets and GNU Octave media. Optical practicum in physics laboratories can not be done during pandemics. So the solution that can be offered is to use simulations on optical subjects of diffraction material. In the simulation making activities students can learn and explore about the phenomenon of diffraction. Simulations using the equations used in the research of Zhang et al. in 2013. This simulation is used to visualize the effect of variations in different parameters such as wavelengths and gap widths in Fraunhofer diffraction patterns. This paper has successfully simulated Fraunhofer's diffraction using spreadsheets as well as GNU Octave. This distance learning allows students to develop fraunhofer computational computational skills and conceptual understanding of diffraction

Corona Virus (Covid-19) is a new type of virus that is transmitted from human to human through the mouth, nose and eyes. This virus attacks the respiratory system which can lead to death. This virus makes the world restless, because it is a new type of virus, so many parties do not know and do not understand how to deal with it. One thing that can be done to reduce the risk of being exposed to Covid-19 is to be disciplined in implementing health protocols. Health protocols are only limited to efforts to protect themselves from patient droplets, but do not provide full protection. SMAN 2 Mataram is one of the schools with 1685 students and 36 study groups. The large number of students and groups makes SMAN 2 Mataram vulnerable to Covid-19 transmission. There is no other choice, except to prepare students as early as possible to have awareness in mitigating the Covid-19 disaster at school. One of the efforts made is literacy education for the Covid-19 disaster mitigation. Implementation of Covid-19 disaster mitigation literacy education through Covid-19 disaster mitigation learning with the Covid-19 disaster mitigation literacy learning model. The research was conducted in class X MIPA1 SMAN 2 Mataram which resulted in students' awareness of the Covid-19 disaster mitigation in the form of inadequate knowledge and application of health protocols, even though they received sufficient information and knowledge about Covid-19. The role of the school in the form of a task force must be optimized to control students in implementing health protocols so that students feel safe when doing activities at school.

This study aims to determine the effect of the NHT and TPS learning models on student achievement, the effect of motivation on student achievement, and the interaction between learning models and motivation on student achievement. This type of research is experimental research. The population in this study were all students of class VII MTs. NW Wanasaba totaling 60 people consisting of 3 classes, namely: class VIIA, VIIB and VIIC. The research sample was class VIIA and VIIB which was obtained by means of Cluster Random Sampling. The data collection technique was carried out using multiple choice objective test method. The prerequisite test used is the normality test and homogeneous test, where the normality test uses the chi-square test and the homogeneity test uses the Bartlet test. While the data analysis technique used to test the hypothesis is the Two Way ANOVA test and the Scheff test for further ANOVA testing. The results of the analysis in this study indicate that there is an influence of the NHT and TPS learning models on student achievement, there is an influence of motivation on student achievement, and there is no interaction between learning models and motivation on student achievement.

Method has been carried out. Research is done on mild steel zincalume type with immersion treatment (NaCl 3.5%) for 10 days, and 30 days and without immersion. Mild steel is laser irradiated (Nd-YAG 1064 nm, 7 ns) with energy of 120 mJ, and the data is taken with an accumulation of 3, delay time of 0.5 µs. Elements identification is done by taking data from up to 75 μm from the surface. The results of the analysis with LIBS showed immersion for 10 days, the corrosion rate and hardness of mild steel increased with 30 days immersion. The increase in the corrosion rate of mild steel is indicated by decreasing the value of dissolved oxygen intensity, the electrochemical reaction is fast. The decrease in the corrosion rate is indicated by the increase in the intensity value of Zn and Al elements associated with the formation of a passive film on the metal surface as a protective layer to protect further corrosion attacks.

The demand for implementing industrial revolution education 4.0 is the use of information technology in the learning process. Virtual Reality (VR) media in learning is one of the uses of technology in its implementation. Utilization of VR media must also be accompanied by including the role of local wisdom by using musical instruments sampe. It is hoped that through learning using VR media based on local wisdom it can improve students' critical thinking skills. This study aims to improve critical thinking skills and instill the value of local wisdom in students. The method used in this research is an experimental method with the form of pre-experimental research design and one-group pretest-posttest design research design. Samples were selected using probability sampling techniques. The research sample was the second semester students of the Physics Education Study Program of IKIP PGRI Pontianak. The instrument used was a critical thinking skills test and a questionnaire. This study obtained qualitative and quantitative data, where quantitative data were analyzed using statistical analysis t test to see the increase in students' critical thinking skills. Based on the analysis of the results of the critical thinking test, it was concluded that there was an increase in students' critical thinking skills using VR media based on local wisdom, this is because VR media provides students with direct experience in seeing the concept of vibrations and sound waves through 3D animated visualization of musical instruments until.

Nusa Tenggara is one of the areas with a high level of seismic activity in Indonesia because this area is located between the Indian Ocean plate, which moves northward and pushes the Eurasian plate. One method that is often used to determine an earthquake's epicentre is the Tensor Moment Inversion method. This study aims to determine the moment tensor magnitude of each earthquake event and determine earthquake characteristics based on the earthquake focus mechanism in Nusa Tenggara from 2018 to 2019. The earthquake with a magnitude of ≥ 5.7 SR and to find out the fault parameters, namely strike, dip, and rake using waveform data. One method that is often used to determine an earthquake's epicentre is the Tensor Moment Inversion method. The results showed that the fault planes formed were reverse faults and oblique faults. It has been calculated the moment tensor for each of the six components, namely Mxx, Myy, Mzz, Mxy, Myz and Mxz. From the results of the focal analysis of the 2018-2019 Nusa Tenggara earthquake mechanism, the values of the fault plane orientation parameters such as strike, dip and rake are obtained. For strikes in Nusa Tenggara on area 1, namely: 73° to 122°, Dip: 20° to 72° and Rake: 53° to 139°. While in field 2 for a strike, it is 232° to 280°, Dip 28° to 75°, Rake: 52° to 102°.
