Abstract

The research has been carried out to determine the wavelength of the POF laser using a diffraction grating. The diffraction grating used consists of three kinds of grid constants, namely 100 lines/mm, 300 lines/mm, and 600 lines/mm. Furthermore, the variation of the distance between the grid and the screen with a length of 40 cm, 60 cm, and 90 cm is carried out. The results showed that the wavelength of the POF laser light was between 664.07 nm-728.31 nm and the red monochromatic light source obtained the interference pattern of light on the screen as well as red monochromatic light. Based on the results of the research, it can be proven that the wavelength obtained from the use of a diffraction grating to measure the wavelength of the red laser is close to the wavelength value of 664.07 nm.

Abstract

ABSTRAKTekanan zat cair dapat dipelajari melalui percobaan, yang memerlukan alat percobaan untuk mempelajarinya, penggunaan alat percobaan tekanan zat cair sangat minim digunakan di sekolah, hal ini disebabkan para guru belum mengetahuinya, terutama di SMP N 1 kecamatan Jambi luarkota Kabupaten  Muaro Jambi yang menyebabkan kurang optimalnya proses pembelajaran IPA di sekolah tersebut. Pengabdian kepada masyarakat ini memiliki tujuan untuk penerapan dan mengadakan pelatihan kepada guru-guru di sekolah tersebut dengan membuat alat percobaan praktikum tekanan zat cair  yang telah didesain oleh dosen dan teknisi di lab fisika universitas Jambi. Pelaksanaan pengabdian pada masyarakat ini terdiri dari beberapa tahap yaitu studi pendahuluan yang terkait dengan analisis situasi di sekolah dan analisis permasalahan mitra, diantaranya adalah kurangnya pengetahuan guru  membuat dan pengguanaan alat percobaan praktikum tekanan zat cair. Program yang dilakukan adalah demonstrasi, dan membuat alat percobaan praktikum tekanan zat cair. Dari hasil pengabdian ini diperoleh tanggapan dari guru bahwa guru sangat antusias mengikuti program yang telah dilaksanakan, guru telah dapat menggunakan alat percobaan praktikum tekanan zat cair. Kata kunci: alat percobaan praktikum; tekanan zat cair; SMPN 1 Muaro Jambi. ABSTRACTLiquid pressure can be studied through experiments, which require experimental equipment to study it. The use of liquid pressure experimental equipment is very minimal in schools, this is because teachers don't know about it, especially at SMP N 1, Jambi sub-district, out of town, Muaro Jambi Regency, which causes sub-optimality. science learning process at the school. This community service aims to implement and provide training for teachers at the school by making practical liquid pressure experiment equipment that has been designed by lecturers and technicians in the physics lab at Jambi University. The implementation of this community service consists of several stages, namely preliminary studies related to situation analysis at school and analysis of partner problems, including the teacher's lack of knowledge in making and using liquid pressure practical experiment equipment. The program carried out is a demonstration, and making practical experimental equipment for liquid pressure. From the results of this service, a response was obtained from the teacher that the teacher was very enthusiastic about participating in the program that had been implemented, the teacher was able to use the liquid pressure practical experiment equipment. Keywords: practical experimental equipment; liquid pressure; State Junior High School 1 Muaro Jambi.

Abstract

Inadequate learning facilities in the Department of Physics Education contribute to the lack of student involvement during modern physics lectures. The learning approach primarily revolves around lecturers, and the effectiveness of Zoom for online learning among students is limited. Therefore, the aim of this research is to design a virtual lab-based learning module integrated with project-based learning to enhance students' conceptual understanding. This research employed a development method with the 4D model. The research subjects included two expert validators to assess the product's feasibility, five students for small-group trials, and 22 students for effectiveness trials. Validators were given questionnaires to evaluate the module's feasibility, while students were given questionnaires to gauge their responses to the module. To evaluate the efficacy of the module, students underwent pre-tests and post-tests consisting of 5 essay questions. Analysis encompassed consolidating validation outcomes and student feedback. Concurrently, test results were assessed using N-Gain tests and paired t-tests. The research outcomes indicated that the integration of virtual lab-based learning with PBL in modern physics was both feasible and effective in enhancing students' conceptual comprehension.
