The Effect of Learning Biophysics with STEM Approach on Science Process Skills and Critical Thinking: Field Study on Application of NA-AOGS for Increasing Soybean Productivity and Growth Rate

Abstract

Efforts to fulfill food security to anticipate population growth in Indonesia need to be supported by universities through research and community service. The application of the Natural Animal Audio Organic Growth System (NA-AOGS) with a STEM (Science, Technology, Engineering, and Mathematics) approach is an effort to help the community increase crop yields and accelerate the growth of soybeans (Glycine max (L.) Merill). The research method used is R&D (Research & Development) which is modified from Cennamo and Kalk (2018). This model is in the form of a spiral cycle using 5 (five) main activities as follows: (1) defining the product conceptual; (2) designing research products; (3) demonstrating the product in a limited trial; (4) developing the product through the process of evaluating the test results, and (5) presenting the product to the public. The direct impact of learning is the improvement of science process skills and critical thinking of students participating in the Biophysics course at the Natural Sciences Study Program, Universitas Negeri Yogyakarta. This is due to the effective application of STEM to link science learning with contextual technology and engineering (NA-AOGS), environmentally friendly technology (only using natural animal sound frequency variables), mathematical elements in data analysis, and analysis of soybeans plant growth charts. The economic impact of this research is the scientific contribution in the form of adaptation of agricultural technology so that it can increase soybean yields (an increase of 130.38% on an area of 2750 m2). The novelty and contribution of this research is the integration of science learning with agricultural techniques and technology with a STEM approach so that it can improve the welfare of farmers in educational institutions as a new model in science learning.

Pre-service teacher in STEM education: An integrative review and mapping of the Indonesian research literature

“…In the Indonesian databases, 17 articles were published in seven of 54 Sinta STEM-related journals. Six articles (Irwanto et al, 2022;Ngabekti et al, 2019;Rokhimawan et al, 2022;Rosana et al, 2021;Rusydiyah et al, 2021;Yulianti et al, 2022) All of the 110 researchers published at most 1 article as first author. The authors in our corpus published at most two articles, either one as the first author or both as coauthors.…”

“…Rusydiyah et al (2021) found that a PST STEM teaching internship program increased the perception and skills. STEM interventions conducting field study activities (Rosana et al,2021) through the application of NA-AOGS (natural animal audio organic growth system) technology (with soybean crops) enhances science process skills and critical thinking skills.…”

“…• interdisciplinary spaces that connect STEM disciplines to solve a problem- Chai et al (2020) used integration to create a STEMQuest, Rosana et al (2021) applied STEM in a transdisciplinary manner to a real-world issue.…”

Stem-Based Learning Process Analysis of Students' Science Process Skills

“…The STEM approach supports student creativity by integrating knowledge, skills and abilities in solving problems (Haryadi et al, 2020). The application of the STEM-based learning process involves students directly in independent learning activities in an effort to improve human thought processes from various more advanced fields (Rosana et al, 2021). Some students use the STEMbased learning process as their best experience and want the activity time to be extended as proof that students are interested in the learning process (Özkul et al, 2020).…”

“…The application of STEM-based learning has increased science process skills in students' knowledge (Bhakti et al, 2020;Farach et al, 2021;Khamngoen et al, 2021;Özkul et al, 2020). STEM learning that directly involves students has a positive impact so that the work they get can be utilized by many people (Rosana et al, 2021). The STEM approach is integrated to develop products, processes and systems that benefit the lives of students (Yulia, 2021).…”
