Abstract

Penelitian ini bertujuan untuk menggambarkan persepsi guru Biologi SMA di Kota Semarang terhadap materi yang dianggap mudah dan sulit diajarkan, serta kendala dan strategi pembelajaran yang diterapkan. Penelitian ini menggunakan pendekatan deskriptif kualitatif dengan teknik pengumpulan data melalui angket daring yang diisi oleh 34 guru Biologi dari berbagai SMA Negeri dan Swasta. Hasil penelitian menunjukkan bahwa materi yang dianggap mudah diajarkan adalah keanekaragaman hayati, sistem pencernaan, pertumbuhan dan perkembangan, serta ekosistem. Sebaliknya, materi metabolisme, imunitas, evolusi, dan genetika dianggap sulit karena sifatnya yang abstrak dan kompleks. Kendala utama yang dihadapi guru meliputi konsep abstrak, istilah asing, keterbatasan media, kurangnya konsentrasi siswa, dan keterbatasan waktu. Untuk mengatasi hal tersebut, guru menerapkan strategi seperti Project-Based Learning (PjBL), Problem-Based Learning (PBL), dan Discovery Learning. Penelitian ini menyarankan perlunya dukungan pelatihan guru, media pembelajaran yang memadai, dan kolaborasi antar guru guna meningkatkan efektivitas pembelajaran Biologi di SMA.

Abstract

The 3-dimensional LED board of the digestive system (PALED 3D-SD) is a learning media that was developed on the basis of analyzing the problems and needs of students. Based on the results of observations in the field, students still have difficulty in learning, especially in understanding the concept of the human digestive system material so that it has an impact on learning outcomes that are not optimal. This is due to the character of the material of the digestive system that cannot be sensed directly by the five senses of students. The learning media used so far have not optimally facilitated students' understanding of concepts. The availability of visual media (torso) of the human digestive system in schools has not been able to display a wide range of material, namely showing the flow of human digestive bioprocesses. This study aims to analyze the validity of the PALED 3D-SD media developed according to media experts and material experts, analyze the practicality of the media according to teachers and students, and analyze the effectiveness of the media in improving students' conceptual understanding through indicators of N-gain test results, class classical completeness, and average difference test. This research is a type of R&D (research & development) research using the ADDIE model through the analysis, design, development, implementation, and evaluation. The validity test of PALED 3D-SD media was obtained from the assessment of 2 media experts and 2 material experts. The practicality test of the media used samples from class XI MIPA 9 and teachers at SMA N 5 Semarang, while the media effectiveness test through a quasi-experimental design used samples from class XI MIPA 5 (control class) and XI MIPA 6 (experimental class) at SMA N 12 Semarang. The results of the media validity test show that the PALED 3D-SD media is very valid according to media experts and material experts. The results of the media practicality test show that the PALED 3D-SD media is considered very practical according to students and teachers. The results of the media effectiveness test show that PALED 3D-SD is effective in improving students' conceptual understanding based on the results of the N-gain test which is in the medium category, the results of classical class completeness are obtained by the percentage of completeness that has met the effective criteria and is higher than the control class, and the test results average difference statistic which shows that there is a difference in learning outcomes (concept understanding) between the group that learns to use PALED 3D-SD and the group that learns to use video. The conclusion based on this research is that the PALED 3D-SD media developed is valid, practical, and effective in improving students' conceptual understanding.

Abstract

Background: The prevalence of stroke in Indonesia has been increasing and has had a significant impact on individuals, families, and society. There is a pressing need for innovative assistive devices that support independent therapy and enhance patient motivation to improve post-stroke productivity. This study aimed to design and develop a post-stroke rehabilitation assistive device utilizing electromyography (EMG) technology. Methods: This study employed a research and development (R&D) design. Data were collected through documentation studies, interviews with physiotherapists, observations, and focus group discussions (FGDs). A documentation study was conducted using the medical records of stroke patients. Interviews were conducted with physiotherapists, and observations were carried out to understand patients’ therapeutic activities. Results: This study provided alternative therapy by developing post-stroke rehabilitation aids with EMG technology. Based on the documentation study, 88% of patients experienced ischemic stroke with a good level of consciousness (E4V5M6), indicated by the Glasgow Coma Scale (GCS) score of 15. Conclusion: This phenomenon supported the development of electrical therapy innovations to accelerate stroke recovery. This study successfully designed a hand therapy device using EMG technology to improve patients’ motor function, particularly among those with E4V5M6 levels of consciousness and limited motor skills.
