Abstract

Weighted Logistic Regression (WLR) is a method used to overcome imbalanced data or rare events by using weighting and is part of the development of a simple logistic regression model. Parameter estimation of the WLR model uses Maximum Likelihood estimation. The maximum likelihood parameter estimator value is obtained using an optimization approach. The Genetic algorithm is an optimization computational algorithm that is used to optimize the estimation of model parameters. This study aims to estimate the Maximum Likelihood Weighted Logistic Regression with the applied genetic algorithm and determine the significant variables that affect the working status of individuals in Malang City. The data used is the result of data collection from the National Labor Force Survey of Malang City in 2020. The results of the analysis show that the variable education completed and the number of household members has a significant effect on individual work status in Malang City.

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

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

Keluarga berisiko stunting merupakan keluarga yang memiliki faktor-faktor yang dapat meningkatkan risiko terjadinya stunting pada anak. Jumlah keluarga berisiko stunting termasuk data cacah (count data) yang umumnya dimodelkan menggunakan regresi Poisson. Namun, model regresi Poisson mengasumsikan kondisi equidispersi, yaitu nilai rata-rata sama dengan varians. Overdispersi terjadi ketika varians lebih besar daripada rata-rata. Dalam kasus seperti itu, model alternatif yang lebih sesuai diperlukan. Tujuan dari penelitian ini adalah untuk menentukan model terbaik jumlah keluarga yang berisiko stunting pada tingkat kecamatan di Provinsi Papua Barat pada tahun 2024 dengan menggunakan regresi Generalized Poisson, Quasi Poisson, dan Binomial Negatif. Data yang digunakan merupakan data sekunder dari Badan Kependudukan dan Keluarga Berencana Nasional (BKKBN) Provinsi Papua Barat yang mencakup 86 kecamatan. Variabel independen yang digunakan adalah jumlah keluarga tidak mempunyai sumber air minum utama yang layak, jumlah keluarga tidak mempunyai jamban yang layak, jumlah PUS 4 Terlalu, dan jumlah keluarga bukan peserta KB modern. Hasil analisis menunjukkan bahwa data mengalami overdispersi dengan nilai sebesar  berdasarkan uji Deviance dan  berdasarkan uji Pearson Chi-Square. Berdasarkan kriteria Root Mean Square Error (RMSE), model Quasi Poisson memberikan nilai RMSE terkecil sebesar , dibandingkan Generalized Poisson sebesar  dan Binomial Negatif sebesar . Oleh karena itu, model terbaik untuk memodelkan jumlah keluarga yang berisiko stunting di Provinsi Papua Barat pada tahun 2024 adalah regresi Quasi Poisson.

Abstract

Mathematics learning at the junior high school level requires instructional media that can create an active, interactive, and enjoyable learning environment to help students better understand mathematical concepts. This study aimed to describe the responses of eighth-grade students at SMP Negeri 27 Manokwari toward the use of Matching Games in mathematics learning on the topic of radical and exponent operations. This research employed a quantitative descriptive approach involving 28 eighth-grade students as the research subjects. Data were collected through a student response questionnaire using a Likert scale consisting of aspects of learning motivation, student engagement, media appearance and visual design, and the usefulness of the game. The data were analyzed using percentage techniques to determine the level of student responses toward the instructional media used. The results showed that the Matching Games received positive responses from students, with percentages of 75.6% for learning motivation, 83.04% for student engagement, 71.13% for media appearance and visual design, and 78.87% for the usefulness aspect, all categorized as practical. These findings indicate that the Matching Games was able to create a more active, engaging, and enjoyable mathematics learning environment while helping students understand mathematical concepts through direct activities of matching questions and answers. Therefore, the Matching Games can be used as an alternative mathematics learning media at the junior high school level, particularly for the topic of radical and exponent operations in grade VIII.
