Abstract

This study aims to analyze the influence of biogeochemical cycle learning based on the local environmental context of Ende Regency on the critical thinking skills of class X students of MAN Ende. The study uses a quantitative approach with a quasi-experimental design of the nonequivalent control group design. The experimental class obtained learning based on the context of the local environment through the stages of orientation, problem identification, discussion, and reflection integrated with Problem Based Learning (PBL) strategies, while the control class used conventional learning. The research instrument was in the form of HOTS questions that had met the validity and reliability (Cronbach Alpha = 0.743). Data analysis was carried out using normality, homogeneity, ANCOVA, effect size calculation, and N-Gain tests. The results showed that there was a significant difference in critical thinking skills between the experimental and control groups after controlling for students' initial abilities. The experimental class N-Gain value of 0.5009 was higher than the control of 0.3108. These findings show that learning based on the local environmental context is able to create meaningful learning and improve students' critical thinking skills on biogeochemical cycle materials. ABSTRAK Penelitian ini bertujuan menganalisis pengaruh pembelajaran daur biogeokimia berbasis konteks lingkungan lokal Kabupaten Ende terhadap keterampilan berpikir kritis siswa kelas X MAN Ende. Penelitian menggunakan pendekatan kuantitatif dengan desain quasi experimental tipe nonequivalent control group design. Kelas eksperimen dengan 30 subjek penelitian memperoleh pembelajaran berbasis konteks lingkungan lokal melalui tahapan orientasi, identifikasi masalah, diskusi, dan refleksi yang diintegrasikan dengan strategi Problem Based Learning (PBL), sedangkan kelas kontrol dengan 30 subjek penelitian menggunakan pembelajaran konvensional. Instrumen penelitian berupa soal HOTS yang telah memenuhi validitas dan reliabilitas (Cronbach Alpha = 0,743). Analisis data dilakukan menggunakan uji normalitas, homogenitas, ANCOVA, perhitungan effect size, serta N-Gain. Hasil penelitian menunjukkan adanya perbedaan signifikan dalam keterampilan berpikir kritis antara kelompok eksperimen dan kontrol setelah mengontrol kemampuan awal siswa. Nilai N-Gain kelas eksperimen sebesar 0,5009 lebih tinggi dibandingkan dengan kelas kontrol sebesar 0,3108. Temuan ini menunjukkan bahwa pembelajaran berbasis konteks lingkungan lokal mampu menciptakan pembelajaran bermakna dan meningkatkan keterampilan berpikir kritis siswa pada materi daur biogeokimia.

Abstract

This research aims to determine the implementation of the Project Based Learning (PjBL) model to enhance the learning activities of third-grade students at SD Negeri Tlogomas 2, Malang City, in the subject of Pancasila Education. Using the Classroom Action Research (CAR) approach, this study was conducted in two cycles involving planning, implementation, observation, and reflection. The project of creating a Pop Up Book became the main focus, where students collaborated to illustrate the values of Pancasila in the context of our ethnic group's wealth. The research results show a significant increase in student learning activities, from 46,91% in the first cycle to 86,52% in the second cycle. These findings indicate that the PjBL model not only enhances student engagement but also deepens their understanding of Pancasila concepts. This research provides new insights for educators regarding more interactive and engaging teaching methods, and emphasizes the importance of relevant learning experiences to enhance student motivation and participation in the learning process.

Abstract

Micro-scale urban green infrastructure provides localized ecosystem services, yet quantifying its carbon dynamics remains a methodological challenge due to satellite resolution limits and the structural assumptions of generalized models. This study evaluates carbon stock distribution across 68 individual trees within a heterogeneous 0.8-hectare institutional urban forest at a microcatchment resolution, analyzing the validity of pantropical allometry.  The stand exhibits an estimated mean carbon density of 45.38 Mg C/ha, totaling 36.34 Mg. Critically, the high coefficient of determination value of 0.9422 primarily reflects structural dependency within the allometric formulation rather than independent ecological variability. Furthermore, the Gini coefficient value of 0.654 confirms severe structural biomass asymmetry. The carbon pool is disproportionately concentrated within a limited cohort of exactly 6 Large Old Trees with a diameter exceeding 60 cm, predominantly Samanea saman. Census data reveals that the top 5% of the largest individuals manage 28.3% of the vegetative carbon, while the top 10% and top 20% control 47.3% and 66.2% of the cumulative reservoir, respectively. Within this micro-forest, inverted J-shaped diameter distributions were insufficient to ensure evenly distributed carbon storage. Consequently, urban green planning must prioritize the targeted retention of dominant biomass anchors over raw sapling quantity. Preserving these established large trees contributes significantly to institutional carbon governance, providing an empirical framework for sustainability metrics such as the UI GreenMetric.

Abstract

This research is motivated by the high demands for student-centered learning in the 21st century, while the teaching of viruses at the secondary school level is still dominated by conventional memorization-oriented methods without linking abstract concepts to contextual scientific problems. The focus of this research problem is directed at testing the effectiveness of a contextual teaching module based on the OIDDE (Orientation, Identify, Discussion, Decision, and Engage in Behavior) model on improving students' conceptual understanding. Using a quantitative approach with a quasi-experimental design in the form of a pretest-posttest control group design, the research's key stages were carried out in a structured manner through purposive sampling involving 70 10th-grade students at SMAN 2 Sampit. The experimental group received instruction using the OIDDE-based module, while the control group received conventional instruction. Quantitative data were collected using a multiple-choice test and analyzed inferentially through ANCOVA, N-Gain scores, and Cohen's d. The research findings showed that the experimental group achieved an average post-test score of 87.00, significantly exceeding the control group, which scored 73.86 based on the ANCOVA analysis (p < 0.05). The learning improvement was categorized as moderate, with an N-Gain value of 0.6466 and a Cohen's d effect size of 2.916, which is considered very strong. The main conclusion confirms that the integration of OIDDE-based contextual modules has proven effective and significantly improves students' conceptual understanding in teaching viruses. ABSTRAK Penelitian ini dilatarbelakangi oleh tingginya tuntutan pembelajaran berpusat pada siswa di era abad ke-21, sementara pengajaran materi virus di tingkat sekolah menengah masih didominasi metode konvensional berorientasi hafalan tanpa mengaitkan konsep abstrak dengan masalah ilmiah kontekstual. Fokus masalah riset ini diarahkan pada pengujian efektivitas modul ajar kontekstual berbasis model OIDDE (Orientation, Identify, Discussion, Decision, and Engage in Behavior) terhadap peningkatan pemahaman konseptual para siswa. Menggunakan pendekatan kuantitatif dengan desain eksperimen semu berbentuk pretest-posttest control group design, tahapan penting penelitian dijalankan secara terstruktur melalui purposive sampling yang melibatkan 70 siswa kelas X di SMAN 2 Sampit. Kelompok eksperimen mendapatkan pengajaran memanfaatkan modul berbasis OIDDE, sedangkan kelompok kontrol menerima instruksi konvensional. Data kuantitatif dihimpun menggunakan tes pilihan ganda yang dianalisis secara inferensial melalui uji ANCOVA, skor N-Gain, dan Cohen’s d. Temuan penelitian menunjukkan bahwa kelompok eksperimen meraih skor rata-rata pascatest sebesar 87,00, secara signifikan melampaui kelompok kontrol yang memperoleh skor 73,86 berdasarkan hasil analisis ANCOVA (p < 0,05). Peningkatan pembelajaran berada pada kategori sedang dengan nilai N-Gain sebesar 0,6466 serta ukuran efek Cohen’s d sebesar 2,916 yang tergolong sangat kuat. Simpulan utama menegaskan bahwa integrasi modul kontekstual berbasis OIDDE terbukti efektif dan signifikan meningkatkan pemahaman konseptual peserta didik pada pengajaran materi virus.
