Abstract:
This research was conducted to complete the teaching materials, namely the worksheets used by teachers. This research is also based on the lack of use of student worksheets in SMA Negeri 5 Palangka Raya. Teachers often use textbooks and modules in the learning process rather than using student worksheets. The purpose of this study was to determine the needs of students for the use of STEM-based student worksheets in class XI on dynamic fluid material. The research instrument used was a questionnaire distributed to students via google form. Based on the results of the needs analysis, 74.1% of students stated that physics is difficult to learn and understand, because it uses a lot of formulas. The online system is the main reason students have difficulty understanding physics material. Teaching materials that are often used by teachers in learning physics are textbooks. Student modules and worksheets are used very rarely and have a fairly low percentage of 33.3% and 25.9%, respectively. Therefore, it is necessary to develop STEM-based worksheets on dynamic fluid materials.

Abstract:
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.

Abstract:
Plastic Plastic is a daily human need, excessive use of plastic has caused serious environmental problems and health problems for humans. The manufacturing process is not environmentally friendly and takes 10 - 50 years to decompose naturally by soil microbes. Therefore, the problem of plastic waste needs a solution, namely waste processing using the combustion pyrolysis method without air pollution which produces by-products in the form of liquids, steam, and solids that have economic value. In this study, Low Density Polyethylene (LDPE) Polyethylene terephthalate (PET) plastic was processed by the pyrolysis method with variations in temperature (70,90,100,125,145) °C and processing time (30,60,90,120,150) minutes. For liquid output, the mass produced from PET (574 grams) is more than that of LDPE (197 grams) obtained at a temperature of 100 °C. The density of the oil produced by pyrolysis in Low Density Polyethylene (LDPE) is close to the density value of gasoline fuel of 731.250 kg/m3, while PETE plastic which is close to the density of gasoline is 767.213 kg/m3 and 784.615 kg/m3 the density is close to ethanol fuel. For solid output, the mass produced from PET (588 grams) is less than LDPE (1740 grams) The solid output quality of LDPE is more sturdy and strong than PET.

Abstract:
This study aims to analyze the learning outcomes of prospective physics teachers in terms of cognitive and learning styles. The sample consisted of 47 prospective physics teachers at the University of Mataram. The instruments used consisted of the Group Embedded Figures Test (GEFT), the VAK learning style questionnaire, and the learning outcomes test instrument. The research data were then categorized and analyzed using descriptive statistics to see a picture of student learning outcomes in terms of their learning styles and cognitive styles. Based on the results of data analysis, it can be seen that there are differences in learning outcomes between students who have a field independence (FI) cognitive style and students who have a field dependence (FD) cognitive style. Students who have FI cognitive style tend to get better scores when compared to FD. When viewed from the learning style, it can be seen that the number of students who have visual learning styles is 46.80%, audio is 8.51%, and kinesthetic is 44.68%. Students who have a kinesthetic learning style tend to get better scores when compared to students who have a visual and audio learning style. By paying attention to the characteristics and percentage of students who have FI and FD cognitive styles and students who have visual, audio, and kinesthetic learning styles, one alternative learning that can be used to improve student learning outcomes is cooperative or experimental-based collaborative learning model.

Abstract:
This research examines the physical and chemical properties of the potential contamination of condenser cooling water (heat water) at the 2x7 MW West Sumbawa Steam Power Plant. Method’s this research is direct observation in the field. The determination of the sample point was done by purposive sampling. The results showed that the hot water had met the predetermined quality standards, namely a pH of 8.21, a temperature of 38.50C and a content of free chlorine (Cl2) of 0.03 mg / L. There was an increase in sea water temperature in a radius of 17 meters east and west by 80C from 280C to 360C. Direct discharge of hot water has the potential to pollute the marine prawn environment around the 2x7 MW West Sumbawa PLTU. From the results of the study, it was found that the temperature of the hot water had met the specified quality standard, which was 40oC, but direct disposal caused the sea water temperature to rise, exceeding the set sea water temperature quality standard of 320C and the temperature increase should not be more than 20C from the temperature. at first. The status of sea water quality due to the entry of hot water is determined using a pollution index. From the calculation results obtained PIj of 1.125 at the sample point Outfall 2, meaning that the sea water conditions at a radius of 17 meters are lightly polluted. As a form of control and prevention of pollution due to the entry of high temperature hot water, continuous monitoring is necessary and it is necessary to create a mixing pool between sea water and hot water before the heat is discharged into the sea.

Abstract:
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.

Abstract:
The 4D microgravity method is a development of the gravity method with the time as the fourth dimension. This research was conducted to find a better way of interpreting the 4D gravity anomaly due to fluid injection around the reservoir. Researchers used GRABLOX for the interpretation of 4D anomalies around the reservoir. The results of the inversion of field data using GRABLOX provide the value of the injection fluid infiltration volume, which shows the distribution of the injection fluid movement on the reservoir. Another physical parameter that can be generated from GRABLOX with a modified value is the reduction in oil and gas saturation due to fluid injection. The inversion results using GRABLOX in the field data indicate a change in reservoir rock density up to 0.28 gr/cc associated with a reduction in gas and oil saturation. The reduction in gas saturation due to the injection fluid has the smallest value of 0% and the largest is up to 66%. The reduction in oil saturation only contributes to a density change of 20% of the reduction in gas saturation. The results of the GRABLOX trial on synthetic data and field data show that both can provide an identification of the movement of the injection fluid in the reservoir, as well as provide other physical parameters, ie. the reduction in oil saturation due to fluid injection.

Abstract:
The seismic refraction method is one of the geophysical methods which is based on measuring the response of seismic waves in the soil that are fractured along the soil and rock layers. One of the seismic refraction method application is to determine the layers and rocks types below the surface. This study uses a geophone as a catcher for seismic waves that are emitted below the surface. The waves caught on the geophone are converted into seismic data which can be read in a seismograph. Seismic data read by seismographs are already in digital form and stored in the central unit PASI 16S24-P. The results of the data analysis concluded that below the land surface of the village of Medana, there were 3 rock layers with a thickness of the first layer 3-4 meters, the second layer 2-5 meters and the third layer 10-17 meters. The first and second layers are still in the form of soil (less compact), while the third layer is in the form of rock (compact). The level of hardness (density) will be more compact in linear to the depth, the more the depth will be the more compact the rock. The depth in the form of hard rock starts from 16 meters to 23 meters from the ground level of the village of Medana, Central Lombok.

Abstract:
This study aims to train students' critical thinking skills during the learning process using CCM-CCA assisted by virtual experiments. The material used for research in optics. This type of research uses a quantitative approach. The subjects in the research were 30 physics education students at a university in NTB. The ability to think critically during the learning process is trained with student worksheets equipped with instruments for critical thinking. Learning is carried out for 3 meetings. The results showed that there was an increase in students 'critical thinking skills from the low category with an average score of 38 to the high category with an average score of 75. This fact shows that CCM-CCA learning assisted with virtual experiments can train and even improve students' critical thinking skills in Optical material.

Abstract:
This study aims to determine the effect of the cognitive conflict approach on the critical thinking skills of senior high school students in grade X on straight motion material. This type of research is a pre-experimental research design with One Group Pretest-Posttest Design. The population in this study were all students of class X MIPA SMAN 1 Narmada. The research sample was obtained using a purposive sampling technique, obtained class X MIPA 1 as experimental class 1, class X MIPA 2 as experimental class 2, and class X MIPA 3 as experimental class 3. Data collection on critical thinking skills used essay test as many as 5 questions. Hypothesis test analysis used a statistical paired sample t-test and showed that Ho was rejected and Ha was accepted. This shows that the cognitive conflict approach affects the critical thinking skills of students in straight motion material. This approach can be an alternative solution for various methods/models/approaches in learning physics.

Abstract:
This study aims to determine the effect of the application of guided inquiry learning models with the practice of converting heat to electricity to improve critical thinking skills. The population of this research is all students of class XII Science of SMA Negeri 1 Way Jepara. The selection of research samples using purposive sampling techniques with a sample of class XII Science 5 totaling 33 students. The research design used was One Group Pretest-Posttest. Learning is done by conducting practicum activities using a set of guided inquiry-based heat energy conversion devices. The tool used in practicum activities is an advantage in this study because there has been no previous research that uses practicum learning methods with tools to convert heat energy to electricity. Practicum activities carried out on two learning topics or practicum twice. In practicum activities topic one is about the unit thermoelectric generator module specifications and in practicum activity topic two is regarding the thermoelectric generator circuit to turn on the LED lights. Data were tested by N-gain analysis, normality test, Paired Sample T-Test. Based on the results of the Paired Sample T-test, it can be seen that the significance value of 0.00 is less than 0.05, it can be concluded that there is an influence of students' critical thinking skills before and after using guided inquiry learning models with energy conversion practicum.
