Artificial light at night (ALAN) is a growing environmental crisis, yet integrating light pollution literacy into science curricula is often hindered by the prohibitive cost of commercial sensors. Addressing this gap, this study examines the DIY CJ’01 photometer as a low-cost, open-source tool for measuring night sky brightness and advancing environmental physics education. Fieldwork across 15 sub-districts in Cimahi City compared the CJ’01 against an industry-standard Sky Quality Meter (SQM). Results demonstrated strong instrumental agreement, yielding a minimal mean discrepancy of 0.16 mag/arcsec². Robust validation via Bland–Altman analysis (bias = −0.157; 95% LoA = −0.465 to 0.152), alongside RMSE (0.218), MAE (0.157), and an Intraclass Correlation Coefficient of 0.832, confirmed its high reliability. Beyond technical validation, embedding the CJ’01 within a Project-Based Learning (PjBL) framework successfully repositioned undergraduate students as active citizen scientists. This instructional design enabled students to translate raw photometric data into baseline sky-brightness maps for municipal use. Ultimately, this experiential approach operationalizes SDG 4.7’s active environmental citizenship, proving that democratized instrumentation can simultaneously serve scientific monitoring and Education for Sustainable Development (ESD).

Penelitian ini bertujuan untuk menganalisis kualitas pengukuran instrumen Force Concept Inventory (FCI) berdasarkan model Rasch serta memetakan miskonsepsi siswa pada materi gaya dan gerak. Penelitian ini menggunakan pendekatan kuantitatif deskriptif dengan melibatkan 62 siswa sekolah menengah atas yang telah mempelajari konsep dasar mekanika. Instrumen yang digunakan terdiri atas 30 butir soal pilihan ganda, dan data dianalisis menggunakan perangkat lunak Winsteps untuk mengevaluasi kualitas instrumen serta pemahaman konseptual siswa. Hasil penelitian menunjukkan bahwa FCI memiliki kualitas pengukuran yang baik, ditunjukkan oleh terpenuhinya unidimensionalitas (22,6%), kesesuaian butir yang memadai, serta reliabilitas yang cukup baik (reliabilitas item = 0,85; reliabilitas person = 0,51). Nilai item separation sebesar 2,41 menunjukkan variasi tingkat kesulitan butir yang baik, sedangkan nilai person separation sebesar 1,01 menunjukkan bahwa variasi tingkat kemampuan siswa masih terbatas. Namun demikian, performa siswa secara keseluruhan masih rendah, dengan rata-rata persentase jawaban benar hanya sebesar 21%, yang mencerminkan rendahnya pemahaman konseptual dan adanya miskonsepsi yang cukup signifikan. Analisis lebih lanjut menunjukkan bahwa siswa cenderung mengaitkan gerak dengan keberadaan gaya secara terus-menerus serta menghubungkan arah gerak dengan besar gaya yang bekerja. Selain itu, siswa juga mengalami kesulitan dalam memahami independensi komponen gerak pada kinematika, khususnya pada konsep gerak peluru. Temuan ini menunjukkan perlunya pendekatan pembelajaran yang menekankan pemahaman konseptual dan keterpaduan konsep-konsep fisika untuk membantu mengurangi miskonsepsi siswa secara lebih efektif.

Critical thinking is a core competency required in 21st-century education, but a valid and reliable instrument for assessing this skill within the topic of rotational dynamics remains limited. This study aims to develop and validate a critical thinking skills assessment instrument for senior high school students on the topic of rotational dynamics, employing the Rasch model for comprehensive validation. Instrument development followed the ADDIE model, involving 34 students during the implementation and evaluation phases. The instrument comprises 27 items constructed based on Facione's critical thinking aspects. Content validity analysis yielded a mean Aiken's V of 0.93, exceeding the critical threshold of 0.80. Unidimensionality testing revealed a raw variance explained by measures of 28.9% (>20%), with unexplained variance in contrasts 1–5 of the PCA residuals ranging from 5.8% to 9.9% (<15%), indicating that the instrument consistently measures a single construct. Twenty-six of the 27 items demonstrated fit to the Rasch model. Reliability analysis yielded an item reliability of 0.81 (good), a person reliability of 0.68 (fair), and a Cronbach's Alpha of 0.72 (good). Wright Map and Item Characteristic Curve (ICC) analyses further confirmed the alignment between item difficulty levels and student ability levels. The developed instrument is demonstrated to be valid and reliable for measuring critical thinking skills among senior high school students in the context of rotational dynamics.

Objective: The present research aims to analyze the development, trends, and intellectual structure of research on the role of local wisdom approaches in character building among students through a bibliometric study. Method: Bibliometric analysis using Scopus-indexed publication data for the 2014–2024 period. Data were obtained through a search using the keywords "local wisdom" and "character", resulting in 87 documents that met the analysis criteria. Results: Data processing was carried out using Microsoft Excel for frequency analysis and descriptive statistics, and VOSviewer to map collaboration networks and keyword relationships. The results show that publications on local wisdom and character education experienced a significant upward trend, peaking in 2020. Indonesia had the highest number of publications, while Ganesha University of Education and I Wayan Suastra were the most productive institutions and authors, respectively. Keyword network analysis identified three main clusters: character education and learning, local culture-based character education, and character building through local wisdom. The findings also indicate that the integration of local culture into character education has become an increasingly dominant theme since 2021. The implications of this research emphasize the importance of using local wisdom values as a contextual character education strategy relevant to students' cultural identities. Novelty: Presentation of a comprehensive bibliometric mapping of the relationship between local wisdom and character education, while also identifying trends, key actors, and remaining research opportunities in this field.

This study examines the effectiveness of a physics learning design that integrates a scientific approach with Wasaka local wisdom to strengthen students’ performance character. The Wasaka (Waja Sampai Kaputing) philosophy emphasizes perseverance, diligence, and commitment in accomplishing academic tasks. A descriptive–quantitative method was applied to 30 physics education students. Hard work and perseverance were assessed using observation rubrics, while learning outcomes were measured through essay tests. Results revealed a significant improvement in performance character, with hard-work scores increasing from 1.49 to 4.86 and perseverance from 1.42 to 4.86, yielding an average gain of 0.96 (high). Learning outcomes also improved moderately (N-Gain = 0.43–0.55). The findings confirm that the Wasaka-based scientific design effectively enhances students’ work character through reflective and inquiry-oriented learning. These results imply that integrating local wisdom within scientific pedagogy provides a meaningful pathway for developing scientific and character-based competence in higher education.
