Di masyarakat, termometer yang biasa digunakan untuk mengukur suhu berbasis air raksa atau alkohol. Namun, ada beberapa kelemahan termometer air raksa atau alkohol. Termometer alkohol memiliki kelemahan yaitu dinding kaca menjadi sedikit basah, sulit membaca suhu yang diukur, dan alkohol tidak berwarna. Oleh kerena itu dibuat termometer sederhana yang memiliki keunggulan seperti pembacaan suhu yang lebih teliti, lebih aman digunakan dan bahan-bahan dalam pembuatan termometer lebih sederhana. Penelitian ini dilakukan dengan cara memvariasikan setiap lilitan kawat untuk melihat perubahan yang terjadi. Data yang diperoleh dari penelitian di Logger pro dalam bentuk grafik dan nilai yang terukur. Setalah data diperoleh data di pindahkan ke MS excel yaitu nilai t waktu, nilai dari T suhu dan I Intensitas. Hasilnya Rentang suhu yang paling baik untuk melihat kemiringan kurva adalah pada suhu 38 - 100 ºC. Pada saat rentang suhu tersebut terjadi perubahan nilai yang cukup baik sehingga bisa diperoleh nilai konsistensi yang paling baik adalah pada kawat dengan 150 lilitan, nilai R2 = 0,99 dengan persamaan y = -5.5246x + 4174,5.

The performance of a thin layer of Cu/Ni as a cryogenic sensor is produced by electroplating at various angles with the aid of a 200G parallel magnetic field. Liquid nitrogen (LN2) is a low-temperature medium with temperatures varying from 0oC to -200oC. The characterization includes the sensor voltage range, sensor resistance, and sensor sensitivity. Thermocouple TCA-BTA -200oC to 1400oC is used as a temperature calibrator. The results showed that all sensors could measure the LN2 temperature in the range of 20oC to -200oC corresponds to the thermocouple's ability to measure up to -200oC. Each sensor has its advantages, but the sensor produced from coating each 3 minutes sample with an angle of 90o has the largest output voltage range up to 0.058 V, and the coating at an angle of 0o with the sensitivity level as a function of T is S(T) = 0.0051 - 0.002T, while the 3 minutes coating sensor with an angle of 60o has the smallest voltage range of 0.0439 V and sensitivity (1.88 ± 0.05) V/oC.

This study aimed to enhance student learning outcomes in the field of work and energy within senior high schools through the development of evaluation instruments based on higher-order thinking skills (HOTS). Higher-order thinking encompasses advanced cognitive abilities such as analysis, evaluation, and creative problem-solving. The evaluation instrument created was meticulously designed to encourage students to think critically, solve intricate problems, and apply physics principles to real-world scenarios. The research methodology employed the development research approach. The instrument development process comprised several stages, including needs analysis, instrument design, validation, and revision. To ensure the instrument's precision and validity, experts in physics education and educational evaluation actively participated in the validation process. The resulting evaluation instrument included a combination of multiple-choice questions and open-ended responses. Students underwent assessment using this instrument following their study of work and energy. Evaluation data were subsequently analyzed through both quantitative and qualitative methods. The outcomes demonstrated a significant improvement in student learning achievements concerning work and energy when using evaluation instruments founded on higher-order thinking. Students who utilized this instrument exhibited superior critical thinking skills, enhanced problem-solving abilities, and an improved capacity to apply physics concepts in real-life situations. This study provides invaluable recommendations for educators and curriculum developers, advocating for the adoption of higher-order thinking-based evaluation instruments in high school physics education. Such an approach has the potential to bolster students' higher-order thinking capabilities and augment their learning outcomes in the context of work and energy. In summary, the successful development and validation of the HOTS based evaluation instrument for 10th-grade high school physics students studying work and energy attest to its viability. Rigorous evaluations from both subject matter experts and media specialists consistently affirmed its suitability across diverse aspects, encompassing appearance, content, and language. Educators, who play a pivotal role in instrument implementation, lauded its effectiveness in teaching work and energy concepts. Positive feedback from students, the primary beneficiaries of this evaluation instrument, underscores its widespread acceptance and appropriateness. In sum, this research underscores the instrument's strong validity and practicality for evaluating students' grasp and application of work and energy principles in high school physics, endorsing its capacity to augment learning outcomes.

This study aims to validate the psychometric properties of a video-based assessment rubric designed to evaluate the pedagogical and professional competencies of physics prospective teachers. The validation process employed the Rasch model to examine item reliability, person reliability, item fit, category functioning, and the separation index. Data were collected from 61 participants using a 25-item rubric that covered various aspects, including Pancasila values, instructional structure, student-centered learning, professional ethics, and evaluation of learning. The results showed that the item reliability was high (0.83), while person reliability was moderate (0.75), with a person separation index of 1.75. Some items exhibited misfit with the Rasch model, indicating the need for revision or refinement. Analysis of category functioning revealed overlapping probabilities between adjacent categories, suggesting that the response scale could benefit from more precise distinctions. Overall, the rubric demonstrated acceptable psychometric quality for assessing the competencies of physics prospective teachers, although several items and scale structures require improvement to enhance measurement precision
