Abstract

Breast cancer remains one of the most prevalent and life-threatening diseases worldwide, highlighting the urgent need for accurate and interpretable diagnostic models. While machine learning has shown promise in classification tasks, many existing models lack transparency and overlook the individual contribution of cellular features essential for clinical decision-making.This study proposes an integrative and explainable framework to identify the most influential cellular-level features in distinguishing between benign and malignant breast tumors. Using a publicly available dataset comprising 569 observations and 32 numerical features, we conducted a multi-step analysis. Feature relevance was first evaluated using Pearson correlation. Random Forest and Recursive Feature Elimination (RFE) were employed to rank and refine the feature subset, followed by Principal Component Analysis (PCA) for dimensionality reduction and pattern visualization. SHapley Additive exPlanations (SHAP) were utilized to interpret individual predictions. Complementary statistical tests, including t-tests and chi-square analyses, assessed associations between tumor characteristics and diagnosis. A logistic regression model was developed to evaluate predictive performance.Key cellular features—such as mean radius, texture, and concavity—were consistently identified as highly predictive of diagnosis. RFE demonstrated that fewer than 10 features were sufficient for optimal classification. The logistic regression model achieved high accuracy, offering a simpler yet effective alternative for prediction.By combining statistical methods with interpretable machine learning, this study presents a transparent and clinically relevant approach to breast cancer diagnosis. The integration of SHAP values bridges the gap between model performance and interpretability, supporting more informed and personalized clinical decisions. Future work should consider external validation, image-based features, and patient demographic variables to enhance generalizability.

Abstract

Cervical cancer is the fourth most common cancer in women globally, with 64,000 new cases in 2020. In Indonesia, cervical cancer ranks second after breast cancer, with 36,633 cases accounting for 17.2% of all cancers in women. This case has a high mortality rate of 21,003 deaths accounting for 19.1% of all cancer deaths. The purpose of this study was to determine the factors that influence women's compliance with early detection of cervical cancer, including individual, social, and health service factors. This research is a quantitative research with analytical survey with cross sectional approach. Sampling using simple random sampling technique with a sample size of 112 respondents with inclusion criteria of women aged 25-50 years who have been married, willing to be respondents and can read and write well. Data analysis using descriptive frequency test, chi square test, and multiple logistic regression test. The results of this study obtained a relationship between age p value (0.000), education p value (0.104), occupation p value (0.002), parity p value (0.000), general health condition p value (0.018), distance to health facilities p value (0.006), knowledge p value (0.021), family support p value (0.011), and the role of health workers p value (0.000) with women's compliance with early detection of cervical cancer. The results of multiple logistic regression test obtained the most influential variable, namely age p value (0.045) with women's compliance with early detection of cervical cancer Based on statistical tests obtained the results of the most influential factor, namely age factor. The conclusion of this study is that it is hoped that this study can increase women's knowledge regarding cervical cancer screening.

Abstract

Dismenore merupakan keluhan menstruasi yang sering dialami remaja putri dan dapat menimbulkan ketidaknyamanan fisik maupun psikologis, seperti nyeri perut, kelelahan, serta gangguan konsentrasi belajar. Dismenore yang tidak ditangani dengan baik berpotensi mengganggu aktivitas sehari-hari, menurunkan kualitas hidup, dan menyebabkan ketidakhadiran di sekolah. Salah satu upaya yang efektif untuk mengatasi permasalahan tersebut adalah melalui edukasi kesehatan reproduksi yang tepat dan mudah dipahami oleh remaja. Pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan remaja putri tentang dismenore serta upaya pencegahan dan penanganannya. Kegiatan dilaksanakan di Desa Margorejo, Kecamatan Margorejo, Kabupaten Pati melalui dua tahap pertemuan dengan metode ceramah, diskusi, tanya jawab, dan focus group discussion (FGD). Sasaran kegiatan adalah remaja putri. Evaluasi dilakukan melalui pre-test dan post-test untuk menilai peningkatan pengetahuan peserta. Hasil kegiatan menunjukkan bahwa sebagian besar peserta mengalami peningkatan pengetahuan yang signifikan, ditandai dengan kemampuan menjelaskan pengertian, penyebab, gejala, serta penatalaksanaan dismenore baik secara farmakologis maupun nonfarmakologis. Selain itu, peserta menunjukkan sikap lebih terbuka dan aktif dalam membahas permasalahan menstruasi. Kegiatan ini memberikan dampak positif dalam meningkatkan pemahaman dan kesiapan remaja putri dalam mengelola dismenore secara mandiri. Edukasi dismenore direkomendasikan untuk diintegrasikan ke dalam kegiatan posyandu remaja sebagai upaya berkelanjutan dalam meningkatkan kesehatan reproduksi remaja
