Abstract

The implementation of the Merdeka curriculum as an effort to improve the quality of education focuses on 21st-century skills, including critical thinking skills, which are essential for problem-solving. Evidence indicates junior high school students exhibit low problem-solving and cognitive ability. This study aims to analyze the differences and levels of problem-solving ability and cognitive outcomes in science after implementing a Problem-Based Learning model supported by Peer Tutoring. This quasi-experimental research used a non-equivalent control group design at Semarang State Junior High School 8, with cluster random sampling. Data were gathered through observation, test, and documentation. The research results showed a significant improvement in problem-solving ability and cognitive outcomes in science after implementing the Problem-Based Learning (PBL) model with Peer Tutoring. This is evidenced by the results of an independent t-test, which found that tcount was greater than ttable. The average posttest problem-solving score in the experimental class was higher (80.8) than in the control class (70.7). Similarly, the average posttest score for cognitive learning outcomes in science in the experimental class was higher (81.6) than in the control class (74.4). Analysis of problem-solving ability level and cognitive learning outcomes level showed an increase in the number of students in each indicator's good and very good criteria.

Abstract

Climate change has emerged as a global crisis with severe consequences for tropical and coastal regions. Pekalongan Regency, Indonesia, exemplifies these challenges, facing recurrent floods and landslides that threaten livelihoods and infrastructure. Risk mapping is urgently needed to guide adaptation strategies, yet many regions face constraints due to limited data availability. This study develops a multi-hazard risk mapping approach that integrates Geographic Information System (GIS) technology with stakeholder participation through Public Participation GIS (PPGIS). Hazard and vulnerability analyses were conducted using disaster records, socio-economic indicators, and spatial datasets, validated through Focus Group Discussions (FGDs) with government agencies and local stakeholders. The findings were synthesized into a structured four-stage framework encompassing stakeholder education (Kick-off), preliminary spatial analysis, participatory indicator validation, and finalization of risk maps. Results reveal distinct spatial patterns: flood risks dominate northern coastal and riverine villages, while landslide hazards are concentrated in the southern highlands. Stakeholder involvement not only improved data validity but also enhanced local adaptive capacity. The proposed PPGIS framework provides a transferable model for participatory climate resilience planning, particularly in data-scarce regions such as the global south area.

Abstract

Science education can be enriched by integrating local culture and wisdom, particularly through the exploration of mangrove ecosystems. Mangroves not only play an essential ecological role but also embody local knowledge that can be linked to scientific concepts. This study aims to identify and describe the local wisdom of the Nipah Panjang, Kubu Raya Regency, West Kalimantan community in utilizing various mangrove species as a source of contextual science learning. A descriptive qualitative design with an ethnopedagogical approach was employed, combining literature review, document analysis, and brief field observations. The findings reveal that six dominant mangrove species, Avicennia alba, Avicennia marina, Bruguiera gymnorrhiza, Excoecaria agallocha, Rhizophora apiculata, and Rhizophora mucronata, are utilized in diverse ways according to their biological traits and bioactive compounds. Their uses include construction materials, firewood, charcoal, traditional medicine (e.g., for eye treatment, anti-inflammatory purposes, and gastric remedies), and support for honeybee cultivation. Such practices highlight the integration of ethnoscientific knowledge with science concepts, including ecosystem adaptation, plant structure, wood properties, and bioactive compounds. By bridging modern science with local wisdom, science education can become more contextual and meaningful, while fostering environmental awareness and a conservation-oriented mindset toward coastal ecosystems.
