Abstract

Kincir Air adalah salah satu contoh alat energi terbarukan yang dimanfaatkan untuk pembangkit listrik. Namun, geometri bilah kincir air sederhana masih harus diteliti. Penelitian ini bertujuan untuk menganalisis besar arus dan tegangan listrik, menganalisis daya listrik, dan membandingkan nyala lampu yang dihasilkan dari 3 jenis geometri bilah kincir air. Pengukuran arus dan tegangan listrik dengan metode mengatur selektor multimeter sebesar 20mA dan 20V. Besar daya listrik yang dihasilkan menggunakan rumus . Menggunakan 3 jenis geometri bilah kincir air yang berbeda, yaitu kotak, datar dan lengkung. Geometri 1, 2 dan 3 menghasilkan arus listrik rata-rata sebesar 0,0088A; 0,0056A; dan 0,0096. Besar tegangan listrik rata-rata yang dihasilkan sebesar 1,327; 0,337 dan 0,827. Nyala lampu rata-rata yang dihasilkan dari 3 jenis geometri bilar kincir air yaitu mati dan redup. Serta besar daya listrik rata-rata yang dihasilkan dari 3 jenis geometri sebesar 0,0117; 0,0019 dan 0,0079. Berdasarkan hasil penelitian, geometri bilah kincir air yang menghasilkan daya listrik paling besar adalah kotak. Tetapi, geometri kincir air masih harus diteliti lebih lanjut menggunakan alat yang lebih canggih.

Abstract

Program KKN UIN Syarif Hidayatullah di Desa Cipaeh, Tangerang, telah sukses memberdayakan masyarakat, khususnya kaum perempuan, melalui Workshop pembuatan sabun cuci piring. Kegiatan ini tidak hanya membekali peserta dengan keterampilan baru, tetapi juga membuka cakrawala ekonomi baru. Dengan metode Participatory Action Research (PAR), Workshop ini mengajak masyarakat secara aktif berpartisipasi dalam proses pembelajaran. Melalui penyuluhan dan praktik langsung, para peserta, terutama ibu rumah tangga, kini mampu memproduksi sabun cuci piring berkualitas sendiri. Keterampilan ini tidak hanya mengurangi pengeluaran rumah tangga, tetapi juga membuka peluang usaha yang menjanjikan. Sabun cuci piring buatan sendiri yang ramah lingkungan dan berdaya saing tinggi dapat dipasarkan di lingkungan sekitar, bahkan berpotensi menjadi produk unggulan desa

Abstract

Science literacy is an important competency in facing global challenges, as emphasized by international assessments such as PISA. Current physics assessment instruments used in schools are not aligned with the PISA 2025 framework, especially in measuring higher-order thinking skills. This study aims to identify gaps in the use of physics test instruments that refer to science literacy at the school level based on the PISA 2025 framework. This study uses a mixed-methods explanatory sequential design method, analyzing 923 questions: daily tests, textbooks, practice questions, 2013 curriculum teaching materials, and independent curriculum modules. The questionnaire was given to 85 students and four teachers in 4 schools, namely Jakarta and South Tangerang. The results showed that only 6.9% of the questions measured the identification of scientific information, while those measuring higher-order skills, such as analysis, were 2.9% and evaluation of evidence was 1.9%. Interestingly, 83.3% of the questions were irrelevant to the PISA science literacy criteria. This study reveals the mismatch of assessment in schools with international standards and recommends the development of contextual and PISA 2025. These findings provide an important foundation for educators and policymakers in improving the quality of science learning

Abstract

This study aims to develop a valid, reliable, and practical science literacy test instrument based on the PISA 2025 framework as a tool for assessing the science literacy abilities of junior high school students in a contextual and in-depth manner. The issue of low science literacy in Indonesia, where 53.60% of students are in the very low category, highlights the urgency of providing an evaluation instrument that can comprehensively represent scientific thinking abilities. This achievement is closely related to the lack of student training using international assessment-based testing instruments such as PISA during the learning process. The research method used was Research and Development (R&D) with a 4-D development model (Define, Design, Development, Dissemination). The instrument was developed based on four dimensions of science literacy (competence, context, knowledge, and cognitive level) within the PISA 2025 framework and covers topics in the science subject, namely electricity, waves, and magnetism. Content validation was conducted by content, instrument, and language experts, while empirical testing was carried out to evaluate the quality of the test items. The research results showed that the instrument had high content validity (CVI = 0.93; CVR = 0.8–1). The average validity of each item reached 0.60. The instrument showed good consistency in terms of reliability, as indicated by the Omega McDonald coefficient of 0.79 for the combination of essay and complex multiple-choice questions, and the Cronbach’s Alpha value of 0.68 for multiple-choice questions analysed separately. Most items were categorized as moderately difficult (72.73%) and had good discriminative power (63.63%). Additionally, the practicality value of 78.85% indicates that the instrument is easy to use in an educational context. Therefore, this instrument is suitable for use as a science literacy assessment tool aligned with the PISA 2025 framework and supports the development of higher-order thinking skills in national assessments.    Keywords: science literacy, instruments, assessment, PISA.
