Abstract

Abstrak - Penelitian ini bertujuan menganalisis efektivitas program Klinik Matematika dengan pendekatan Embedded Learning Analytics (PPLAM) dalam meningkatkan pemahaman siswa kelas VII pada materi operasi bilangan bulat. Penelitian menggunakan metode kuasi-eksperimen dengan desain one-group pretest–posttest. Intervensi dilaksanakan melalui rangkaian kegiatan pretest, latihan terstruktur, dan posttest dalam satu sesi pembelajaran. Subjek penelitian berjumlah 25 siswa yang dipilih secara purposif berdasarkan hasil diagnosis kesulitan belajar. Data diperoleh dari tes hasil belajar dan rekaman aktivitas latihan, kemudian dianalisis menggunakan uji t berpasangan, Normalized Gain (N-Gain), dan effect size (Cohen’s d). Hasil analisis menunjukkan peningkatan yang signifikan, dengan nilai rata-rata N-Gain sebesar 0,578 (kategori sedang) dan effect size sebesar 2,164 (kategori sangat kuat). Analisis PPLAM lebih lanjut menunjukkan bahwa kualitas latihan memberikan kontribusi substansial terhadap hasil posttest dengan nilai R² sebesar 0,70. Temuan ini menegaskan bahwa integrasi PPLAM dalam program Klinik Matematika berperan penting dalam memantau proses belajar dan meningkatkan efektivitas pembelajaran remedial jangka pendek pada materi operasi bilangan bulat.Kata kunci : Klinik Matematika; Operasi hitung Bilangan Bulat; N-Gain; Effect Size; Learning analytics; Abstract - This study examines the effectiveness of a Mathematics Clinic program integrated with Embedded Learning Analytics (PPLAM) in improving seventh-grade students’ understanding of integer operations. A quasi-experimental method with a one-group pretest–posttest design was employed. The intervention consisted of a pretest, structured practice activities, and a posttest conducted within a single learning session. The participants were 25 students selected purposively based on initial learning difficulties. Data were collected from achievement tests and practice-session records and analyzed using a paired-sample t-test, Normalized Gain (N-Gain), and effect size (Cohen’s d). The results indicated a significant improvement, with a mean N-Gain of 0.578 (moderate category) and a large effect size (d = 2.164). Further analysis using PPLAM revealed that practice quality contributed substantially to posttest performance, as indicated by an R² value of 0.70. These findings confirm that PPLAM plays a critical role in monitoring learning processes and enhancing the effectiveness of short-term remedial instruction in integer operations.Keywords: Mathematics Clinic,; Integer Operation;  N-Gain; Effect Size; Learning analytics;

Abstract

This study aims to examine the key factors influencing the implementation of GASING mathematics, particularly teachers’ perception, attitude, competence, and school support, in a rural educational context. The study addresses the limited integration of these variables within a single analytical framework, especially in remote areas such as Kaimana. A mixed-methods approach was employed involving 14 teachers who have experience in implementing the GASING method. Quantitative data were collected using structured questionnaires and analyzed using descriptive statistics and Spearman correlation, while qualitative data were obtained through open-ended responses and analyzed using thematic analysis. The results indicate that all variables are categorized as high to very high, reflecting positive responses toward the GASING method. Correlation analysis shows that teacher competence has the strongest relationship with implementation (r = 0.62), followed by school support (r = 0.52), perception (r = 0.43), and attitude (r = 0.35). These findings highlight the central role of teacher competence in ensuring effective implementation. Qualitative findings further reveal that despite positive perceptions and attitudes, teachers still encounter challenges related to limited practical skills and inconsistent institutional support. This study offers a novel contribution by integrating multiple teacher-related and institutional factors within a mixed-methods framework in a remote context. The findings imply that strengthening teacher competence through continuous professional development, supported by consistent school policies and resources, is essential for optimizing the implementation of innovative mathematics learning approaches such as GASING.

Abstract

The escalating global clean water crisis, driven by pollution and limited freshwater resources, has intensified the need for efficient and sustainable water treatment technologies. This review critically examines the structure–property relationships of membrane materials and their implications for water purification performance. Comparative analysis of recent studies reveals that hydrophilic membranes with controlled pore size (typically 0.01–0.1 µm) exhibit superior water flux (up to 65 L/m²·h·bar), higher pollutant rejection (>90%), and better fouling resistance than hydrophobic counterparts. Modifications involving nanoparticles (e.g., TiO₂, Fe₃O₄), composites (PES–DLC, PVDF–MOF), and biosurfactants have been shown to enhance hydrophilicity, optimize pore distribution, and extend operational stability. The review highlights the trade-off between permeability and selectivity, emphasizing the critical roles of pore size, contact angle, and surface chemistry in balancing efficiency and durability. It concludes that future membrane development should integrate nanostructure engineering, eco-friendly materials, and data-driven optimization to achieve adaptive, high-performance membranes for sustainable water purification.
