Abstract

Getaran Harmonis Sederhana (GHS) adalah gerakan bolak-balik suatu benda melalui titik keseimbangannya dengan frekuensi dan amplitudo yang konstan. Pendulum sederhana merupakan bentuk eksperimen yang umum digunakan dalam pembelajaran IPA untuk menjelaskan konsep getaran harmonis sederhana yakni suatu sistem yang bergerak dan bergetar secara periodik yang terdiri dari benda dengan massa tertentu yang diikat dan dikaitkan dengan benang atau tali tak bermassa (dengan massa yang diabaikan). Bandul adalah benda yang digantung pada tali atau batang dan dapat berayun bolak-balik melalui titik keseimbangannya. Faktor-faktor yang mempengaruhi frekuensi ayunan bandul yaitu panjang tali, percepatan gravitasi, dan massa bandul. Penelitian ini bertujuan untuk membuktikan pengaruh panjang tali terhadap frekuensi getaran ayunan bandul pada massa yang berbeda. Metode penelitian yang digunakan yaitu metode eksperimen dengan memvariasikan panjang tali. Hasil penelitian menunjukkan bahwa frekuensi getaran berbanding terbalik dengan panjang tali. Artinya, semakin panjang tali, semakin kecil frekuensi getarannya. Hal ini dibuktikan melalui hasil eksperimen pendulum sederhana yakni pada data perbandingan pada panjang tali yang berbeda.

Abstract

Physics learning is rarely associated with local wisdom, so many people think the local arts have a separate topic from scientific study. This research analyzes the equilibrium concepts at Tari Banjarkemuning from Sidoarjo, East Java. This qualitative research uses content analysis techniques divided into six steps: unitizing, sampling, coding, reducing, inferring, and narrating. The data were collected by observation, documentation, and interviews. The research indicates that the equilibrium concept at Tari Banjarkemuning is the condition of equilibrium and the center of mass. The equilibrium state is shown in the motion of Embat-Embat and Solah Kembang Turi at the Sagah position (the silent moment of the dancers while inclined the bodies sideways and backward). Then, the center of mass is shown in the motion of Kejer (the dancers raise one leg) and Kencrongan (the dancers at the Tanjak position open- dancers’ legs perpendicularly at the knee). The integration of Tari Banjarkemuning in learning activities is expected for students to understand physics concepts easily. At the same time, it can make meaningful physics learning and build a better character for students.

Abstract

We used a qualitative approach with an explanatory case study method to examine students' conceptual understandings of plant growth and development before and after using the VLab Plantae application. Task-based interviews were applied to 12 ninth-grade students from class IX. Before and After interview, their conceptual understandings of four domains were examined, i.e., imbibition, germination, growth factors, and the growth process. The students were tasked to work with VLab Plantae based on interview protocols. The findings show that VLab Plantae improves students’ conceptual understandings, with the most significant gains in imbibition. Students grasped germination and growth processes through visual experiments with red beans and corn seeds. While all concepts in the four domain were identified during the use of VLab Plantae, our study suggests that teachers remain crucial in guiding students to use the VLab Plantae to comprehend the related concepts.

Abstract

The research is based on challenges in learning, especially in nervous system material, where there are often misconceptions in students about the course of neural impulses and understanding the structure of the nervous system in humans. The purpose of the research is to develop learning media in the form of 3D-MbL puzzle media to help junior high school students understand the concept of nervous system material and conduct a SWOT analysis of the learning media. The research method used is qualitative descriptive, with data collection techniques through observation, documentation, and questionnaires. The instrument used in this study is a validation sheet by two validators, namely material validation and media validation. 3D-MbL puzzle media is made using several tools and materials, with the main ingredients being made using flannel and analyzed using the SWOT method. The study's primary results show that 3D-MbL puzzle media can attract students' interest and hone creative thinking skills during learning. However, there are challenges, such as the media needing help to explain in detail the process of neural impulses and other essential concepts in the material of the nervous system. The opportunity of this 3D-MbL puzzle media can be used as an exciting anatomy of the human body, and the threat is that students do not understand how to use it if the teacher does not clearly explain the use of the media. In conclusion, 3D-MbL puzzle media for the nervous system offers innovations in delivering science learning materials. However, further improvements are needed so that this media can be more optimal in delivering learning materials.

Abstract

Female students of the millennial generation are required to have the ability to recognize and assess opportunities that are relevant to current developments. Business management is a series of activities, practices, and decisions carried out to plan, organize, direct, and control resources and activities in a business or organization to achieve predetermined goals. The purpose of this community service is to train female students on the management of the Millennial Santri Business Studio, especially involving packaging, branding, and sales of processed dragon fruit products as the identity of the Islamic Boarding School's superior products, and expanding offline sales access at bazaars and online on social media. The target of the community service program is 38 female students of Tanwirut Thullab Islamic Boarding School. The method used is the approach of the Millennial Santri Business Studio management training activities used, namely Participatory Rural Appraisal (PRA). The results of the training show that female students have succeeded in implementing safe and attractive packaging steps for processed dragon fruit products. Products are now packaged using containers that are much safer, cleaner, have a more professional visual appearance, and are effectively protected from contamination. In addition, the brand identity "Dapur Santri" as the identity of the superior dragon fruit products of the Islamic Boarding School. Female students expanding their offline sales channels through bazaars and online through social media have significant potential to strengthen business relationships with customers, which can improve profits, marketing and communication strategies, cost efficiency, and effectiveness. The success of this training fostered an entrepreneurial spirit and motivation among the female students. This has resulted in the emergence of a culture of creativity, innovation, and the courage to compete.

Abstract

Natural Sciences (IPA) is an empirical discipline that studies natural phenomena; however, many of the concepts within it are abstract, making them challenging for students to understand. This necessitates the implementation of innovative learning strategies that can facilitate a more concrete bridging of conceptual understanding. One potential solution involves incorporating Virtual Reality (VR) technology into the scientific learning process. The objective of this study is: (1) to analyze the change of students' conceptual understandings before and after the use of immersive VR, and (2) to identify  the food chain concepts students comprehend during learning with VR. The present study employed an exploratory, multi-case study approach, involving a total of 15 junior high school students. The data were collected through a pre-test, semi-structured interviews, and a post-test. The analysis was conducted qualitatively by comparing changes in students' mastery of five concepts: biotic-abiotic components (A), trophic level interactions (B), the role of components in energy flow (C), the influence of food chain interactions on ecosystems (D), and the role of decomposers (E). The findings of the study suggest two primary conclusions. Firstly, there is a notable enhancement in students' comprehension of the food chain concept following the implementation of VR-based learning. Secondly, the utilization of VR media in educational settings provides a substantial enhancement in students' understanding, particularly in the context of abstract concepts related to food chains. These findings suggest that VR can serve as an effective medium for science education, with the potential to enhance conceptual understanding, mitigate misconceptions, and enrich students' learning experiences.   ABSTRAK Ilmu Pengetahuan Alam (IPA) mempelajari fenomena alam secara faktual, namun banyak konsep yang bersifat abstrak sehingga sulit dipahami oleh siswa. Hal ini memerlukan strategi pembelajaran inovatif yang mampu menjembatani pemahaman konseptual secara lebih konkret. Salah satu alternatif adalah mengintegrasikan teknologi Virtual Reality (VR) dalam pembelajaran IPA. Penelitian ini bertujuan (1) untuk menganalisis perubahan penguasaan konsep siswa sebelum dan sesudah pembelajaran dengan VR, dan (2) mengidentifikasi konsep apa saja yang muncul ketika siswa belajar menggunakan VR tentang rantai makanan. Penelitian menggunakan pendekatan exploratory multi-case study dengan melibatkan 15 siswa SMP. Data dikumpulkan melalui wawancara semi-terstruktur dengan tahapan berikut: tes pengetahuan awal, penggunaan VR, dan tes pengetahuan akhir; tes awal dan akhir dilakukan secara lisan dan siswa menjawab secara verbal. Analisis dilakukan secara kualitatif dengan membandingkan perubahan penguasaan siswa pada lima konsep, yaitu komponen biotik-abiotik (A), interaksi tingkat trofik (B), peran komponen dalam aliran energi (C), pengaruh interaksi rantai makanan terhadap ekosistem (D), dan peran pengurai (E). Hasil penelitian menunjukkan bahwa 1) terdapat peningkatan secara kualitatif penguasaan konsep rantai makanan siswa setelah pembelajaran berbasis VR dan 2) beberapa konsep rantai makanan dapat siswa pelajarai ketika menggunakan VR, khususnya pada konsep-konsep rantai makanan yang abstrak. Temuan ini mengindikasikan bahwa VR dapat digunakan sebagai alternatif media pembelajaran IPA yang dapat mengembangkan pemahaman konsep siswa tentang rantai makanan.

Abstract

Di era revolusi industri 4.0, pengembangan scientific creativity pada siswa menjadi aspek krusial dalam pendidikan sains. Penelitian ini melakukan kajian sistematis terhadap 10 artikel penelitian terpublikasi antara tahun 2015-2023 untuk menganalisis efektivitas berbagai model pembelajaran inovatif dalam meningkatkan kreativitas ilmiah siswa. Metode penelitian menggunakan pendekatan systematic review dengan tahapan identifikasi, evaluasi, interpretasi, dan sintesis terhadap artikel-artikel terkait dari database Scopus, Google Scholar, dan Science Direct. Temuan penelitian mengungkapkan bahwa pendekatan pembelajaran berbasis proyek (project-based learning) menunjukkan dampak signifikan dalam meningkatkan kemampuan berpikir divergen siswa. Sementara itu, model pembelajaran berbasis inkuiri (inquiry-based learning) efektif dalam mengembangkan kemampuan merumuskan hipotesis dan merancang eksperimen kreatif. Integrasi teknologi digital seperti simulasi virtual dan augmented reality juga terbukti mampu menstimulasi imajinasi ilmiah siswa. Faktor kunci pendukung meliputi: (1) desain pembelajaran yang berorientasi pada masalah autentik, (2) lingkungan belajar yang mendorong eksplorasi bebas, dan (3) sistem penilaian yang mengakomodasi orisinalitas ide. Implikasi penelitian ini menyoroti perlunya pengembangan kerangka kerja pedagogis yang mengintegrasikan dimensi kreativitas dalam kurikulum sains, serta pentingnya pelatihan guru dalam menerapkan strategi pembelajaran inovatif.
