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.

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.
本研究是为了完成教材，即教师使用的工作表。这项研究也是基于SMA Negeri 5 Palangka Raya缺乏学生工作表的使用。教师在学习过程中经常使用教科书和模块，而不是使用学生的工作表。本研究采用问卷调查的方式，通过谷歌表格发放给学生。根据需求分析的结果，74.1%的学生表示物理很难学习和理解，因为它使用了很多公式。在线系统是学生理解物理材料困难的主要原因。教师在学习物理时经常使用的教材是教科书。学生模块和工作表的使用非常少，分别占33.3%和25.9%的比例相当低。因此，有必要开发基于stem的动态流体材料工作表。

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.
