Abstract

Breast cancer is a health problem that can begin to be influenced from adolescence. This study aims to analyze the effects of body mass index (BMI), age at menarche, and family history on breast cancer risk among female students at SMA Trensains Muhammadiyah Sragen, while also integrating binary logistic regression results into a risk-scoring system for early screening purposes. The study used a cross-sectional analytic survey design with 122 students who had experienced menarche, selected through purposive and stratified random sampling. The analysis included bivariate tests, binary logistic regression, and ROC curve evaluation. Only BMI showed a significant relationship with breast cancer risk (χ² = 27.4; p < 0.001). The logistic regression model was significant (χ² = 35.2; p < 0.001) with an AUC of 1.00, although affected by perfect separation. The regression coefficients were then converted into a risk-scoring system that preserved the data-separation pattern. The scoring system produced an AUC of 1.00 with a cut-off of 2.5; a total of 118 students (96.7%) were classified as low risk and 4 students (3.3%) as high risk. This integration produces a simple screening tool that can be used for health education and early risk detection among adolescent girls. Keywords: BMI, menarche, breast cancer risk, logistic regression, risk scoring. Abstrak Kanker payudara merupakan masalah kesehatan yang dapat mulai dipengaruhi sejak masa remaja. Penelitian ini bertujuan menganalisis pengaruh indeks massa tubuh (IMT), usia menarche, dan riwayat keluarga terhadap risiko kanker payudara pada siswi SMA Trensains Muhammadiyah Sragen, sekaligus mengintegrasikan hasil regresi logistik biner ke dalam sistem risk scoring untuk keperluan skrining dini. Penelitian menggunakan desain survei analitik potong lintang dengan sampel 122 siswi yang telah mengalami menarche, dipilih melalui purposive dan stratified random sampling. Analisis mencakup uji bivariat, regresi logistik biner, dan kurva ROC. Hanya IMT yang menunjukkan hubungan signifikan dengan risiko kanker payudara (χ² = 27,4; p < 0,001). Model regresi logistik signifikan (χ² = 35,2; p < 0,001) dengan AUC = 1,00, meskipun dipengaruhi perfect separation. Koefisien regresi kemudian dikonversi menjadi sistem risk scoring yang mempertahankan pola pemisahan data. Sistem skor menghasilkan AUC = 1,00 dengan titik potong 2,5; sebanyak 118 siswi (96,7%) tergolong risiko rendah dan 4 siswi (3,3%) risiko tinggi. Integrasi ini menghasilkan instrumen skrining sederhana yang dapat digunakan untuk edukasi kesehatan dan deteksi risiko awal pada remaja putri.

Abstract

This research develops a wearable system based on the MPU6050 sensor to monitor infant sleep position as a form of preventing Sudden Infant Death Syndrome (SIDS), which is strongly linked to the prone sleep position. The system utilizes Inertial Measurement Unit (IMU) technology to detect body orientation through accelerometers and gyroscopes. The method used is descriptive quantitative thru tool design, system programming, sensor calibration, and testing against three main parameters: tilt angle accuracy, alarm activation time, and buzzer response. The research results show that the sensor is able to read angles with an average error of 3.8%, which is still below the standard limit of 5%. The alarm system shows an average response time of 0.82 seconds, while the buzzer has an average sound duration of 0.20 seconds with a stable sound. Overall, these findings indicate that the MPU6050-based wearable system functions accurately and responsively, and has the potential to be used as an aid for monitoring infant sleep position.

Abstract

In an effort to reduce dependence on synthetic plastics and curb environmental pollution, the use of organic waste as raw material for bioplastics has become an innovative solution. One potential alternative is the production of environmentally friendly biofilms from bagasse and banana peels, both of which contain cellulose and lignin as the main components for film formation. This study aims to create and test the characteristics of biofilms based on bagasse and banana peels, as well as to determine their level of biodegradability. The research method uses a descriptive experimental approach, with the stages of biofilm production involving mixing, heating, and drying. The tests include folding resistance, biodegradability, and organoleptic tests. The results showed that the biofilm had a folding resistance of 65 times, a biodegradability level of 90% from an initial weight of 11 grams to 1.1 grams, and organoleptic characteristics of a clear brownish color, a distinctive sugarcane aroma, and a flexible but slightly rough texture. Based on these results, the biofilm from sugarcane bagasse and banana leaves has proven potential as an environmentally friendly packaging material that is easily degradable and supports efforts to reduce plastic waste.

Abstract

Anemia remains a major health problem in Indonesia, especially among adolescent girls, with a prevalence of 32% that leads to fatigue, decreased concentration, and low productivity. The concept of developing synbiotic functional foods, a combination of probiotics and prebiotics, was chosen because it can improve gut health and support iron absorption. This study aims to formulate and analyze synbiotic gelato based on yogurt enriched with beetroot (Beta vulgaris L.), katuk leaves (Sauropus androgynus L.), and chia seeds (Salvia hispanica L.) as an alternative food to prevent anemia. This study was conducted from August to October 2025 using qualitative and quantitative descriptive methods through organoleptic, pH, Fe content, and overrun tests. The results showed that sample B was the most acceptable formulation to the panelists based on the organoleptic test. The pH value of the gelato was 5.5, which is within the safe and stable range. The average iron content of 2.3 mg Fe/100 g indicates an increase in functional value through the addition of beetroot and katuk leaves. The overrun value of 28.8–39.6% is still within the ideal range for gelato, resulting in a dense and creamy texture. Thus, yogurt-based synbiotic gelato has the potential to be a food supplement for the prevention of anemia in adolescents.

Abstract

Limbah shampo anti-ketombe mengandung zinc pyrithione (ZnPT) yang bersifat toksik dan berpotensi mencemari lingkungan perairan jika tidak diolah dengan baik. Penelitian ini bertujuan untuk menganalisis kemampuan kacang kedelai (Glycine max L.) sebagai bioadsorben dalam menurunkan kandungan ZnPT pada limbah shampo melalui mekanisme adsorpsi. Bioadsorben dibuat dari ampas kedelai yang dikeringkan dan digranulasi sebelum digunakan pada proses filtrasi sampel. Pengujian meliputi uji pH, uji kualitatif ZnPT, dan uji efektivitas adsorpsi berdasarkan perubahan tinggi endapan Zn(OH)₂. Hasil penelitian menunjukkan bahwa pH larutan tetap stabil pada angka 7,9 setelah proses adsorpsi, sehingga bioadsorben tidak mempengaruhi kestabilan larutan. Uji kualitatif menunjukkan penurunan endapan Zn(OH)₂ dari 5 mm menjadi 2 mm. Nilai efektivitas adsorpsi yang diperoleh sebesar 60%, menandakan bahwa bioadsorben kedelai cukup efektif mengurangi ion Zn²⁺ meskipun belum mencapai kategori efektivitas tinggi. Secara keseluruhan, bioadsorben kedelai memiliki potensi sebagai alternatif ramah lingkungan untuk mengurangi kadar ZnPT pada limbah domestik. Penelitian selanjutnya disarankan mengoptimalkan massa adsorben, ukuran partikel, dan waktu kontak untuk memperoleh hasil yang lebih maksimal.
