Abstract

Pengetahuan siswa tentang pemanfaatan dan masa depan energi menjadi ditekankan dalam pembelajaran fisika. Penelitian ini bertujuan untuk memberikan gambaran desain media belajar fisika materi energi terbarukan. Media belajar yang dirancang adalah pengembangan smart hydroponic bertenaga panel surya. Komponen utama desain smart hydroponic ini adalah panel surya, controller, accu, inverter, sensor TDS, sensor pH, pompa air, dan katup otomatis. Tanaman yang digunakan adalah sayuran jenis Selada. Komponen pendukung yang lain adalah penggunaan nutrisi A dan B sebagai sumber nutrisi tanaman. Sebelum diterapkan sebagai media pembelajaran, media smart hydroponic ini diuji nilai tepat guna dan validitasnya. Hasil uji coba desain alat memberikan hasil yang efektif dan efisien untuk diterapkan pada budidaya tanaman sayur selada.

Abstract

Abstrak. Development of Problem-solving skills is needed in physics to master concepts. This goal can be achieved through the implementation of the right steps. The purpose of this research is to describe models, strategies, media, and instruments that can be used to develop problem-solving skills. Learning models that can be applied include PBL, PIL, Inquiry, IBMR, PO2E2W, Discovery Learning, PjBL, Virtual Laboratory, CPSL, and CTL learning models. Learning strategies can be in the form of peer instruction, scaffolding, Polya strategies, Heller, Keith, and Enderson strategies, knowledge planning strategies, Rosengrant strategies, and visualization of the imaginary world. Various supporting media can be in the form of computing media, the development of teaching materials, mobile applications, and games. The instruments used for assessment and questionnaires.

Abstract

Background: Problem-Based Learning, PBL, is a student-centered approach in science education that promotes conceptual understanding and higher-order thinking by engaging learners with authentic contextual problems. Aims: This systematic review synthesizes how PBL is implemented in science education, what outcomes are most frequently reported, and what barriers commonly hinder its adoption. Method: A PRISMA-guided systematic literature review was conducted using Scopus. Searches employed the terms “problem-based learning,” “science education,” and “science learning.” Eligible studies were empirical journal articles and conference proceedings published from 2017 to August 2025, written in English, and involving participants from elementary school through higher education. Of 388 records identified, 53 studies met the inclusion criteria and were analyzed according to publication trends, research designs, implementation strategies, targeted outcomes, and reported constraints. Results: Across educational levels, PBL was consistently associated with cognitive gains, especially in critical thinking, problem solving, and higher-order thinking skills. The reviewed evidence also indicated affective benefits, including stronger scientific attitudes, improved learning motivation, and enhanced collaboration. Nevertheless, recurring challenges emerged, such as limited instructional time, demanding assessment processes, curriculum coverage pressures, uneven teacher readiness, unequal participation in group work, and gaps in access to learning resources and technology. Conclusion: PBL offers clear promise for improving both cognitive and affective dimensions of science learning, yet its success depends on well-designed contextual problems, adequate pedagogical support, and alignment with learners’ readiness. Strengthening teacher capacity and refining assessment practices are essential to reduce persistent implementation barriers.

Abstract

Global demand for fossil energy continues to increase, affecting both the environment and energy availability. This study aims to describe the energy crisis and its impacts, the adoption of renewable energy (RE), and the educational challenges in addressing these problems in Indonesia.  The Systematic Literature Review method was conducted using Harzing’s Publish or Perish application, which indexed articles from Scopus and Google Scholar, using the keywords “energy crisis,” “renewable energy,” “energy education Indonesia,” and “impact of fossil energy.” The review covered publications from 2017 to March 2025. A total of 116 articles met the eligibility criteria. The results indicate that the environmental impacts include increases in CO2 emissions driven by urbanization, industrialization, and transportation. Globally, RE adoption remains at only 1%. The use of renewable energy in Indonesia is relatively low, at 11.31% of the available energy supply. Indonesia’s educational strategies include establishing specialized schools for the development of RE, curriculum support, and implementing project-based learning. These strategies must be replicated and further developed by other institutions. Through these efforts, Indonesia is expected to become more aware of the limitations and impacts of fossil energy and better able to utilize the availability of renewable energy.
