Abstract

This study aimed to analyze the effect of STEM–Biology integrated physics learning on junior high school students’ 21st-century skills, including critical thinking, creativity, collaboration, and communication. The study employed a quantitative approach using a quasi-experimental design with a nonequivalent control group design. The research was conducted at SMPN 2 Peusangan during the even semester of the 2024/2025 academic year, involving two eighth-grade classes as the experimental and control groups selected through purposive sampling. The experimental group received STEM–Biology integrated physics learning, while the control group received conventional instruction. Data were collected using written tests, 21st-century skills questionnaires, and observation sheets, and were analyzed using t-tests and N-Gain analysis. The results showed that the N-Gain score of the experimental group was in the moderate–high category (0.63), which was higher than that of the control group (0.34). Therefore, STEM–Biology integrated physics learning is effective in developing junior high school students’ 21st-century skills.

Abstract

Agribusiness competitiveness requires adaptation to market, technological, and environmental changes, yet empirical studies integrating business innovation, digital marketing, and environmental sustainability within a single model remain limited, particularly in Bireuen Regency, Indonesia. This study examined the associations of these three factors with agribusiness competitiveness. A quantitative cross-sectional survey conducted in July 2026 involved 80 agribusiness actors selected through purposive sampling. Data were collected using a structured five-point Likert-scale questionnaire and analyzed through partial least squares structural equation modeling (PLS-SEM) in SmartPLS 4. All three factors were positively and significantly associated with agribusiness competitiveness. Environmental sustainability had the largest estimated path coefficient (β = 0.339, p < .001), followed by business innovation (β = 0.292, p = .003) and digital marketing (β = 0.251, p = .009). The model explained 40.6% of the variance in competitiveness (R² = .406). These findings highlight the relevance of business capabilities and sustainable practices to agribusiness competitiveness in this setting. The study contributes an integrated competitiveness model and identifies innovation, digital marketing, and environmental sustainability as relevant priorities for agribusiness development strategies in Bireuen.
