Abstract

Investigating the low mathematics scores of Indonesian students on the PISA assessment can be done by examining the influence of measured predictors, including teacher competence and school resources that have not attracted the attention of Indonesian mathematics education researchers. The research focused on the effect of teacher competencies and the shortage of school resources on students’ mathematics achievement. Secondary data were retrieved from the official PISA website, involving 9,721 students aged 13-15 years from 332 schools after deleting the missing data. All students and schools were recruited using a stratified-two stage sample design and did not meet the exclusion criteria. Multilevel analysis was used to determine the significance of predictors of interest on students’ mathematics achievement. The analysis showed that adaptive teaching, teacher emotional support and teacher enthusiasm contributed to increase students’ mathematics achievement while teacher feedback and the shortage of school resources significantly decreased students’ mathematics achievement. These findings can assist policymakers in setting educational priorities especially related to what teacher competencies should be developed and procurement of school resources.

Abstract

Reduction of cylinder surface resistance can be accomplished by modifying roughness. The surface roughness structure is one of the important parameters which greatly affects the flow of fluid through the cylinder surface. Fluid flow forms a vortex flow pattern with certain characteristics. Therefore, this study aims to analyze the characteristics and effects of fluid flow through the rough surface of the outer wall of the pipe with visualization using Particle Image Velocity (PIV). This research was conducted experimentally at the Faculty of Engineering, UHAMKA. The pipe surface roughness values varied were 0.648 µm and 1.699 µm. The length of the pipe used is 20 cm with a diameter of 2 inches. Measurements are made from the center of the pipe to a distance of 0.16 m. The results show that the surface roughness of the cylinder pipe affects the fluid flow characteristics where the formation of eddies is caused by the addition of the roughness value. The rougher the pipe surface is, the farther the vortex formation will be. The vortex formation closest to the pipe is a pipe with a roughness value of 0.648 µm at a distance of 0.04 m.

Abstract

Pendanaan merupakan aspek fundamental dalam menjamin keberlanjutan dan mutu penyelenggaraan pendidikan. Penelitian ini bertujuan untuk mengkaji bentuk-bentuk pengelolaan sumber dana pendidikan pada satuan pendidikan di Indonesia yang terintegrasi dengan regulasi nasional, potensi lokal, dan inovasi digital untuk mendukung pembiayaan pendidikan yang berkelanjutan. Metode yang digunakan adalah studi pustaka (library research) dengan menganalisis berbagai sumber sekunder seperti jurnal nasional dan internasional, peraturan perundang-undangan, laporan lembaga, dan publikasi ilmiah lainnya. Teknik analisis dilakukan secara deskriptif-kualitatif dengan pendekatan sintesis teoritik dan interpretatif. Hasil penelitian menunjukkan bahwa sumber dana pendidikan di Indonesia berasal dari pemerintah pusat dan daerah, komite sekolah, unit usaha lembaga pendidikan, bantuan alumni, dana masyarakat, serta sumbangan yang tidak mengikat seperti zakat, infaq, sedekah, dan wakaf. Selain itu, inovasi pembiayaan dapat dilakukan melalui kolaborasi dengan pihak ketiga dalam bentuk kerja sama pengelolaan usaha, penelitian bersama, penyediaan layanan masyarakat, hingga digitalisasi program donasi pendidikan. Setiap sumber dana memiliki peluang dan tantangan tersendiri yang perlu dikelola dengan prinsip transparansi, akuntabilitas, dan partisipasi.Simpulan dari penelitian ini menyatakan bahwa strategi pengelolaan dana pendidikan yang integratif dan partisipatif sangat penting untuk memperkuat fondasi keuangan pendidikan yang berkelanjutan. Keterbatasan penelitian ini adalah belum mengeksplorasi secara empiris efektivitas tiap bentuk penggalian dana di sekolah. Untuk itu, direkomendasikan penelitian selanjutnya menggunakan pendekatan studi kasus atau mixed methods untuk menganalisis secara mendalam pengaruh variabel inovasi digital dan kemitraan terhadap efektivitas pembiayaan pendidikan.

Abstract

PISA is an international scale assessment in which it measure mathematical literacy skills. Indonesia was one of the participants who took part in the PISA assessment. PISA results show that Indonesia is still at a low level. In fact, some study show that the ability of Indonesian students to solve PISA questions on the quantity content of students is not good and is still low compared to other content. This research aims to produce PISA-Like math questions with Quantity content that are valid, practical and have a potential effect on mathematical literacy skills. This research using a development research which consists of preliminary, self-evaluation, expert review, one-to-one, small group, and field test stages. The subjects in this study were students of class IX-4 SMP inone of the junior high schools in Medan. The results of this study are PISA-Like questions with Quantity content in valid and practical criteria. From the analysis of students’ answers regarding the potential effect involved in mathematical literacy, the results show that students involve communication skills, reasoning and argument skills, mathematical abilities, representation abilities, devising strategies for solving problems, and using symbolic, formal skill, and technical language and operations.

Abstract

Nahdlatul Ulama (NU) and Muhammadiyah, as pioneers of religious moderation in Indonesia, have a significant influence on education through the development of Islamic Education (PAI) textbooks. The study of the Qur'anic verse used to strengthen the value of religious moderation in PAI textbooks is important, given the diversity of views on the concept of wasathiyah, differences in references, and variations in implementation. The problem of this research is, first, the similarities and differences in the perspectives of NU and Muhammadiyah on determining which Qur'anic verses serve as the basis for religious moderation in PAI textbooks and their application. This research aims to analyze and synthesize studies of Qur'anic verses that serve as the basis for religious moderation in the PAI textbooks of the NU and Muhammadiyah. This research uses a field method with a qualitative approach. The results showed that NU and Muhammadiyah have common ground in making QS: al-Kafirun verse 6 and QS. Al-Hujurat verse 13 is the main reference in developing the value of religious moderation. Students in both the school environment and everyday life can internalize the application of these verses. This finding underscores the importance of inter-organizational collaboration in compiling moderation-based PAI textbooks sourced from the Qur'an. It not only strengthens the nation's harmony and integrity but also increases Indonesian Islamic education's contribution to promoting world peace in the era of disruption.
