Abstract

Penelitian ini bertujuan untuk mengetahui efektivitas pendekatan kreatif dalam meningkatkan kemampuan numerasi, membaca, dan menulis anak di Pondok Baca Senja Papua Cerdas, Manokwari. Sasaran kegiatan adalah anak-anak usia sekolah dasar dan prasekolah yang aktif mengikuti kegiatan belajar di pondok baca tersebut. Metode yang digunakan adalah pendekatan kreatif melalui aktivitas bermain sambil belajar, media visual interaktif, serta kegiatan membaca dan menulis bersama yang menyenangkan. Data dikumpulkan melalui observasi langsung, catatan kegiatan, dan dokumentasi aktivitas belajar. Hasil pengabdian menunjukkan peningkatan kemampuan numerasi, membaca, dan menulis anak serta antusiasme yang lebih tinggi dalam mengikuti kegiatan. Temuan ini menunjukkan bahwa pendekatan kreatif efektif mendukung perkembangan numerasi dan literasi anak secara simultan.

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

This study aims to analyze the effectiveness of the Mathematics Clinic in overcoming the difficulties of seventh-grade junior high school students in integer operations. The research focused on improving students’ learning outcomes through a short learning intervention consisting of a pretest, structured practice, and a posttest conducted within a single day. The method employed was a quasi-experimental design with a one-group pretest–posttest dengan Embedded Learning Analytics (PPLAM). The subjects were 25 seventh-grade students purposively selected based on their identified difficulties in learning mathematics. Data were collected through achievement tests (pretest and posttest) and students’ practice records. The data analysis included a paired t-test to measure the difference between pretest and posttest scores, the calculation of Normalized Gain (N-Gain) to assess the effectiveness of improvement, and effect size to determine the magnitude of the intervention’s impact. In addition, a simple learning analytics approach was applied to examine the relationship between practice quality and posttest results. The findings revealed a significant improvement in students’ learning outcomes with . The mean N-Gain score of 0.578 indicated a medium level of improvement, while the effect size (Cohen’s d = 2.164) was categorized as very large. Furthermore, learning analytics analysis showed an R2 = 0,70 suggesting that practice quality positively contributed to students’ posttest performance. It can be concluded that the Mathematics Clinic is effective as an alternative learning strategy to address difficulties in integer operations, even when implemented within a short time frame.

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.
