EFEKTIVITAS PENGGUNAAN MODUL FISIKA TERINTEGRASI STEM (SCIENCE, TECHNOLOGY, ENGINEERING, AND MATHEMATICS) MATERI USAHA DAN ENERGI DI SMA

Learning carried out during the pandemic is required to develop technology to support student learning effectively. Solutions for students and teachers to carry out learning effectively by using learning media that students can understand independently at home. Learning media that can support students in independent learning are modules. The module usage by educators related to 21st-century skills to balance the world of education in the modern era can collaborate with models, methods, and approaches in learning, one of which is the STEM (Science, Technology, Engineering, and Mathematics) approach. The purpose of this research is to describe the effectiveness of the STEM integrated physics module. The research method is by giving tests to students in the form of pretest and posttest. The subjects of this study were students of MAN 1 Jember class X MIPA 2 as a limited test and X MIPA 3 broad test. Product testing was conducted by researchers using the One Group Pretest-Posttest design. Then analyzed normalized Gain (N-gain) to determine the effectiveness of the module. The results of the analysis of the effectiveness of the module in the limited test obtained an average N-gain of 0.55 in the medium category, while in the broad test it was 0.71 in the high category. Based on the results of the effectiveness analysis that the STEM integrated physics module is in the effective category. Keyword: Module, STEM, efectivity

This research aimed to examine the relationship between refractive index and light intensity in various fluids. This type of this research was experimental research. The measurement data obtained the refractive index values of various fluids, namely the refractive index of spirit, watered, alcohol, oil, and oil respectively 1. 3066 ± 0. 0053, 1. 319 ± 0. 0056, 1. 3422 ± 0. 0061, 1. 438 ± 0. 0054, 1. 576 ± 0. 0068. The data from the measurement of light intensity in various fluids obtained the valued of the intensity of light that passed through spirit, watered, alcohol, oil, and oil, respectively, namely 1220. 8 ± 3. 72 lux, 1219 ± 3. 9 lux, 1216. 2 ± 3, 77 lux, 1202. 6 ± 3. 88 lux, and 1180. 2 ± 4. 07 lux. The results of this research obtained a valued of r = 1 which indicates that the relationship between the refractive index and light intensity was very strong. The conclusion in this studied was that there was a relationship between refractive index and light intensity. This relationship could been seen in the refractive index, the greater the valued in the fluid would made the transmitted light intensity decrease or inversely proportional. Key word: fluid, light intensity, refractive index

PENGEMBANGAN BAHAN AJAR E-LKPD BERBASIS PENGERINGAN IKAN ASIN PADA MATERI SUHU DAN KALOR FISIKA SMA

The research carried out aims to develop teaching materials that are sontextual local wisdom in order to attract student in learning. The teaching materials that will be developed in this research are e-LKPD based on drying salted fish on temperatured and heat materials. The research method used in this research in the ADDIE development model. The ADDIE development model has five stages, namely Analysis, Design, Development, Implementation and evaluation. The research steps are carried out in accordanse with the ADDIE satges. The results of the research conducted, namely at the analysis stage, it was found that the lack of use of alternative teaching materials such as e-LKPD made student less interested during the learning process. Teaching materials that contain observation activities are meeded to improve psychomotor skills in students so that in this study the e-LKPD was developed by containing a simple experiment on drying salted fish. Preparation or writing of e-LKPD materials using the 3d pageflip application. This applicatin has the adavantage of complete features that make the 3d effect look real. This 3d pageflip appication requires a number of computer devices to use and the installation process is quite long. The constraints of this research are that the computer equipment owned by the researcher does not support the isntallation of the 3d pagefip application, the limited time of the study, and the limitation of the researcher in usng the 3d pageflip applicatin so that the research is only carried out until the sdesign stage.

ANALISIS PERUBAHAN SUHU LINGKUNGAN TERHADAP KENYAMANAN MASYARAKAT DI DESA SUMBER TENGAH

Recently, there have been frequent changes of temperature and weather that are unpredictable and very extreme, causing people to feel uncomfortable with them. Therefore, this study aims to analyze the optimal temperature for the comfort of the community in Sumber Tengah Village, Binakal District, Bondowoso Regency. Sumber Tengah Village is located in the western part of Bondowoso and there are still many rice fields and plantations so the temperature is not too hot. Even so, the erratic temperature changes in Sumber Tengah Village also need to be analyzed to find out at what temperature people feel comfortable doing activities. In this study, data collection was carried out in the form of environmental temperature from 5 am to 9 pm for five days to see what time the lowest temperature, highest temperature, and optimum temperature are comfortable for the community. The data obtained will be compared with existing literature for further analysis.

IMPLEMENTASI LESSON STUDY SEBAGAI UPAYA MENINGKATKAN PARTISIPASI AKTIF SISWA DALAM PEMBELAJARAN VIRTUAL

The outbreak of Covid-19 has resulted in learning activities to be carried out virtually. Based on the experience of implementing virtual learning, students do not participate actively in the learning process. Low student participation in education can be seen from the lack of student responses in answering teacher questions in virtual learning. Based on this problem, the authors researched by implementing lesson study as an effort to increase students' active participation in virtual learning. This study aims to increase students' active involvement in virtual education through the implementation of lesson study. This study's subjects were 32 students of Al Falah Islamic Junior High School class VIII.5 semester 2020/2021 academic year with 13 male students and 19 female students. Implementation of lesson study starts on August 18 to September 1, 2020. This type of research is descriptive quantitative research. Data collection was carried out through student active participation observation sheets. Based on the research results in cycle 1, student participation data obtained an average value of 56.28%. While in cycle 2, the student participation data received an average value of 59.56%.

ANALISIS PROSES PEMBELAJARAN IPA PADA MATERI CAHAYA MELALUI LESSON STUDY BERBASIS TBLA (TRANSCRIPT BASED LESSON ANALYSIS) DI KELAS VIII.2 SMP ISLAM Al-FALAH KOTA JAMBI

This study analyzes the science learning process through a TBLA-based lesson study (Transcript Based Lesson Analysis), where the analysis is focused on the teacher-centered and student-centered. There are stages of lesson study that are implemented, namely planning (plan), implementation (do), and reflection (see). This study uses a qualitative approach with a case study research type. This research was carried out in class VIII.2 of Al-Falah Islamic Junior High School in Jambi City from January 18 to February 22, 2021, through 2 research cycles. This study's data source was 32 students of class VIII.2, with details of 20 male students and 12 female students. Qualitative data were obtained through observation and documentation. Observers make statements during the learning process. At the same time, documentation is received from audio/video recordings of the learning process (interactions between teachers and students), which will then be transcribed in learning dialogue. The results obtained are based on the transcript of the conversation, which is made in a word unit graphic. It can be seen that the science learning process in cycle one and cycle two is still dominated by teachers or is teacher-centered. The teacher has allowed students to speak with existing questions and group discussions. The suggestion in this research is that teachers can apply TBLA-based lesson study in the learning process. Analytical techniques like this aim to improve the ability of teachers to enhance further learning processes.
