Abstract

Environmental education plays a crucial role in shaping the character of students as the next generation, enabling them to be aware and concerned about environmental sustainability. Through environmental education, students are equipped not only with theoretical knowledge but also with practical values and skills to encourage them to become agents of change. This study aims to examine the Gunungkidul region as a source of local potential learning information on the topic of environmental change in science or biology learning materials for students. To support its learning activities, this study also adopts environmental education learning trends that can be used as part of efforts to build sustainable environmental education. This research is a literature review, focusing on articles published between 2020 and 2025 to ensure the data used is current and relevant. The results of the study indicate that the Gunungkidul region has great potential as a source of information for science or biology learning for students. In terms of environmental education learning, there are approaches, models, teaching materials, and learning media that teachers can choose or combine to improve the effectiveness of environmental education learning, especially on the topic of environmental change, with the hope that there will be no more gaps in the student learning process, so that student learning outcomes can be more meaningful and sustainable to support environmental sustainability in the future.

Abstract

Rhizobacteria are endophytic bacteria that inhabit plant tissues and the rhizosphere, producing secondary metabolites that support plant growth. This study is an exploratory descriptive investigation aimed at characterizing and identifying IAA- and phytohormone-producing endophytic rhizobacteria isolated from the roots of corn plants (Zea mays L.). The rhizobacteria isolates producing IAA phytohormones were obtained by culturing bacteria in Yeast Peptone Broth (YPB) medium supplemented with L-tryptophan. Bacterial cultures (1 mL) were treated with Salkowski reagent, and absorbance was measured spectrophotometrically at a wavelength of 530 nm. From 14 isolates, five were identified as producing the highest levels of indole-3-acetic acid (IAA), ranging from 17 to 50 ppm. Identification was conducted using the profile matching method to determine the genus of each rhizobacterium by comparing its characteristics with reference genera. Based on 62 tested traits, the five isolates exhibited diverse features, including Gram-positive and Gram-negative bacteria, coccus-shaped morphology, circular and irregular colony configurations, lobate and undulate margins, convex, umbonate, and raised elevations, and colony colors ranging from white to yellowish, along with varied physiological (biochemical) test results. The identification results revealed bacteria with a similarity index of ≥70%, suggesting proximity to the genus Micrococcus (77.4%, isolate N), Rhizobium (80.6%, isolate D), and Shewanella (80.6%, isolate B; 87.1%, isolate V; and 91.9%, isolate E). This research provides an important contribution to the development of biofertilizers aimed at enhancing the growth and productivity of corn plants sustainably.

Abstract

This study aims to examine the effectiveness of integrating the Socio-Scientific Issues (SSI) approach and debate method in biology learning to improve students' reflective thinking skills on the topic of environmental pollution. The method used was a quasi-experimental design with a non-equivalent control group design. The research results were analyzed using N-Gain scores and an Independent Sample T-Test. The results showed a significant increase in students' reflective thinking skills after implementing the integration of SSI and debate (t = –5.857; sig. = 0.000). In conclusion, the integration of the SSI approach and debate method has a positive impact on the development of students' reflective thinking skills, especially on the topic of environmental pollution.   Keywords: Biology, Debate, Environmental pollution, Reflective thinking, SSI
