Abstract

Breast cancer is one of the leading causes of death among women worldwide, making survival analysis essential in evaluating patient survival probabilities. This study aims to estimate the survival function of breast cancer patients based on Estrogen Receptor Status using the nonparametric Kaplan-Meier estimator. Secondary data from the Breast Cancer Survival dataset on Kaggle (n = 4,024 patients) were analyzed. Variables included survival time (Survival Months), event status (Status), and Estrogen Receptor Status (Positive/Negative). Results showed that patients with Estrogen Receptor-Positive status exhibited a higher survival probability compared to Estrogen Receptor-Negative patients, as indicated by the slower decline of their Kaplan-Meier survival curve. These findings confirm that estrogen receptor status is an important prognostic factor in breast cancer and that the Kaplan-Meier estimator provides an effective nonparametric approach to evaluating patient survival

Abstract

This article presents a literature review on various learning models applied to improve mathematics learning outcomes in integral calculus. The 4 studies that form the basis of the literature study have discussions in understanding integral concepts, critical thinking skills, motivation and learning outcomes and the dimensions of character education. These four studies provide a comprehensive picture of the various approaches that can be used to improve students' understanding and learning outcomes in integral calculus. The first study highlights the effectiveness of the Problem-Based Learning (PBL) model in enhancing students' understanding of integral concepts. The PBL model has been shown to encourage active student engagement and sharpen critical thinking skills. The second study compares two learning models, Discovery Learning and Accelerated Learning, focusing on students' learning motivation and mathematics learning outcomes in integral calculus. The results indicate that Discovery Learning is more effective in improving students' motivation and their deeper understanding of integral concepts. The third study implements Lesson study with a PBL approach that incorporates character education in the class. This approach not only improves mathematical understanding but also develops students' character, such as collaboration and curiosity. Meanwhile, the fourth study develops a learning device for integral calculus based on a problem-solving model to enhance students' creative thinking abilities. These four studies demonstrate that problem-based learning models, whether PBL, Discovery Learning, or problem-solving-based instructional devices, are effective in improving students' understanding and critical thinking skills in integral calculus.

Kegiatan dilaksanakan pada bulan Juni 2026 di SMKN 4 Gowa. Metode yang digunakan adalah kombinasi antara ceramah, demonstrasi, dan praktik langsung (workshop). Materi pelatihan meliputi pemanfaatan Desmos, GeoGebra, serta Google Workspace yang mencakup Google Classroom, Google Forms, dan Google Sheets dalam pembelajaran matematika. Hasil kegiatan menunjukkan bahwa rata-rata kompetensi TPACK awal peserta berada pada skor 3,23 dari 5,00, dengan kompetensi terendah pada aspek GeoGebra (2,44) dan Desmos (2,59). Tingkat kepuasan peserta terhadap pelaksanaan kegiatan mencapai rata-rata 4,89 dari 5,00, menandakan kegiatan ini sangat bermanfaat dan sesuai kebutuhan guru. Kegiatan ini memberikan dampak positif terhadap kemampuan guru dalam mengintegrasikan teknologi ke dalam pembelajaran matematika secara efektif dan inovatif.

Abstract

Indonesia has undergone significant healthcare system transformations over the past three decades, including the implementation of universal health coverage in 2014. However, comprehensive long-term analyses of maternal and child health (MCH) trends spanning nearly three decades remain limited. This study examines the evolution of key MCH indicators in Indonesia from 1995 to 2023 to assess progress, identify patterns, and inform future policy directions. We conducted a longitudinal trend analysis using data from the Indonesian National Health Survey (Riset Kesehatan Dasar/Riskesdas) covering the period from 1995 to 2023. Nine key indicators were analyzed: prevalence of health complaints, skilled birth attendance, childhood immunization coverage (BCG, DPT, polio, measles), and breastfeeding practices. Statistical methods included linear trend analysis, Bayesian changepoint detection, correlation analysis, and segmented regression to assess policy impacts. Healthcare utilization patterns, including outpatient care, inpatient care, self-medication, and traditional medicine use, were examined as contextual indicators. Substantial improvements were observed across most MCH indicators over the 28 years. Skilled birth attendance showed the most dramatic progress, increasing from 46.1% (1995) to 95.7% (2023), representing an annual improvement rate of 2.55%. Childhood immunization coverage achieved high levels (>85%) for most vaccines by the 2000s, though measles vaccination remained variable (54-80% range). Breastfeeding patterns showed a structural break in 2015 due to methodological changes, which complicated trend interpretation. Healthcare utilization evolved significantly, with outpatient care increasing from 20% to >50% before declining to 35% by 2023, while self-medication practices rose substantially to 80%. Correlation analysis revealed alignment between health needs and service utilization (r = 0.48 for outpatient care). Changepoint analysis identified accelerated improvements around 2000-2005 and 2014-2015, coinciding with healthcare decentralization and universal coverage implementation respectively. Indonesia achieved remarkable progress in maternal and child health over 28 years, with skilled birth attendance approaching universal coverage and immunization programs maintaining high performance. The implementation of universal health coverage in 2014 coincided with continued improvements, though some recent declines in vaccination coverage warrant attention. The evolution from traditional medicine to modern healthcare services, alongside increasing self-medication practices, reflects maturing health systems requiring adaptive policy responses. Indonesia's experience demonstrates that sustained MCH improvements are achievable in large middle-income countries through systematic health system strengthening, though maintaining momentum requires continuous adaptation to emerging challenges. These findings provide valuable insights for other countries pursuing similar health system transformation goals.

Abstract

The low effectiveness of mathematics learning in secondary schools remains a significant challenge, particularly in relation to teachers’ difficulties in presenting abstract concepts, selecting appropriate instructional strategies, and responding to students’ diverse learning abilities. This condition indicates the need to strengthen teaching practices through reflective and participatory activities that are grounded in real classroom problems. This community service activity aimed to strengthen the teaching practices of mathematics teachers in Gowa Regency through the identification of teaching difficulties as a basis for formulating contextual and applicable learning solutions. The implementation method employed a participatory approach consisting of planning, implementation, and reflection stages. During the implementation stage, teachers were divided into several working groups based on teaching level and teaching experience. Each group conducted focused discussions to identify experienced teaching difficulties, analyze contributing factors, and formulate alternative instructional solutions. Activity data were obtained from group worksheets, discussion results, and group presentations. The activity involved thirty mathematics teachers who were divided into five groups, each consisting of six participants. The results indicated that the first and second groups predominantly identified difficulties in presenting abstract concepts and low student participation, the third group emphasized constraints in selecting instructional models, the fourth group revealed difficulties in learning assessment, and the fifth group highlighted limitations in instructional media. The benefits obtained included increased teachers’ reflective awareness, improved ability to systematically analyze instructional problems, and the development of alternative solutions that were relevant to classroom contexts. This activity confirms that active teacher involvement in identifying teaching difficulties represents an important and innovative approach to strengthening teaching practices based on authentic school needs.
