Abstract

Diabetes mellitus adalah penyakit kronis dengan prevalensi yang terus meningkat, termasuk di Kota Bukittinggi, yang sering menimbulkan stres pada pasien dan membutuhkan dukungan keluarga untuk mendukung pengelolaan diri (self-management). Survei awal di Puskesmas Tigo Baleh menunjukkan sebagian pasien belum mendapat dukungan keluarga memadai, datang berobat tanpa pendamping, serta mengalami stres yang berdampak negatif pada self-management. Penelitian ini bertujuan mengetahui hubungan dukungan keluarga dan tingkat stres dengan self-management pada pasien diabetes mellitus di Puskesmas Tigo Baleh. Desain penelitian menggunakan analitik korelasional dengan pendekatan cross-sectional. Populasi penelitian adalah seluruh pasien diabetes mellitus yang berkunjung ke Puskesmas Tigo Baleh, dengan sampel 69 responden yang dipilih melalui cluster sampling. Instrumen penelitian meliputi kuesioner dukungan keluarga, DASS-42 untuk tingkat stres, dan DSMQ untuk self-management. Analisis data menggunakan uji Spearman Rank. Hasil penelitian menunjukkan 44,9% responden memiliki dukungan keluarga baik, 40,6% memiliki tingkat stres normal, dan 56,5% memiliki self-management baik. Analisis statistik menunjukkan hubungan signifikan antara dukungan keluarga dengan self-management (p=0,000) serta antara tingkat stres dengan self-management (p=0,000). Kesimpulannya, semakin baik dukungan keluarga dan semakin rendah tingkat stres, maka semakin baik pula self-management pasien diabetes mellitus.

Abstract

Background: Calcium is a material that is mostly contained in the Anadara-granose shell. Beta-TCP can be obtained from the hydrothermal process from the Anadara-granose shell. Beta-TCP has a chemical composition that approximates the structure of bones and teeth. Objective:The microencapsulation technique aims to increase stability, reduce side effects and toxic effects of drugs, and prolong the release of ingredients. The encapsulation process is an attempt to inhibit the dissolution speed of Calcium to prevent tunnel defects. Methods: Anadara-granose shell powder was subjected to hydrothermal processing for 18 hours and sintering for 3 hours. The beta-TCP powder was dissolved with aquadest using a magnetic stirrer until it was homogeneous, Na-alginate was dissolved in aquadest until it was homogeneous with a magnetic stirrer then the two solutions were mixed and the CaCl2 solution was dropped. The sample was divided into 3 groups; Pure Beta-TCP(K-); 7 hours stirring (P1); 8 hours stirring (P2). After completion of the stirrer, the samples were centrifuged at 2500 rpm for 6 minutes, then freeze-dried for 12 hours. The level test was carried out using complexometry comparing the pure Beta-TCP group with the Beta-TCP stirrer encapsulation process for 7 hours and 8 hours. Results: The data showed that the average calcium level in K(-) group with pure Beta-TCP was 8.63%, the P1 Beta-TCP group with 7 hours stirrer 2.86%, and the P2 Beta-TCP group with 8 hours stirrer 2.12%. Conclusion: In the Anadara-granosa shell nanoencapsulation process, the calcium level gradually decreased with the longer duration of stirring time

Abstract

B-emission (Be) star is a B type star which shows emission line in its spectrum, especially Hα, caused by the disk surrounding it. One of the Be stars, π Aqr, is a binary Be star in constellation Aquarius which shows variability of double-peaked Hα emission line caused by a circumstellar disk around the primary component. We aim to study recent physical phenomenon which occurs in the disk of π Aqr star based on its spectral data from 2004 to 2024, retrieved from BeSS database, by analyzing the variability of its Hα emission line parameters: the Violet-to-Red peak ratio (V/R), Emission-to-Continuum ratio (E/C), Equivalent Width (EW), Full Width at Half Maximum (FWHM), and peak separation. The variation of V/R ratio from 2004 to 2019 shows period of 84.1 days which corresponds with orbital period of the binary system. However, in 2024, the V/R variability does not show similar cycle period in previous years as the red peak strength dominates throughout most of the year. The EW and E/C increase, indicating rising disk activity and expansion until 2024. Overall increase of red and blue peak separation roughly suggests expansion in Hα region in the disk.

Abstract

Penyakit Tidak Menular (PTM), termasuk hiperkolesterolemia, merupakan salah satu masalah kesehatan yang terus meningkat dan menjadi faktor risiko utama penyakit kardiovaskular. Data WHO menunjukkan bahwa sekitar 45% penduduk dunia mengalami kolesterol tinggi, sementara di Indonesia prevalensinya mencapai 28%. Kondisi ini dipengaruhi oleh gaya hidup tidak sehat, konsumsi makanan tinggi lemak, kurang aktivitas fisik, merokok, serta kurangnya pengetahuan masyarakat tentang pencegahan kolesterol. Penyuluhan kesehatan menjadi salah satu strategi preventif yang efektif dalam meningkatkan pengetahuan, sikap, dan tindakan masyarakat mengenai pengendalian kolesterol. Penelitian ini bertujuan untuk mengetahui pengaruh penyuluhan terhadap perubahan pengetahuan, sikap, dan tindakan masyarakat sebelum dan sesudah intervensi penyuluhan tentang kolesterol di Desa Kasoloang, Kecamatan Bambaira, Kabupaten Pasangkayu. Penelitian menggunakan desain pre-experimental one group pretest-posttest design dengan total sampel berjumlah 23 orang yang dipilih melalui total sampling. Instrumen penelitian berupa kuesioner pengetahuan, sikap, dan tindakan yang diberikan sebelum (pretest) dan sesudah (posttest) penyuluhan. Analisis data dilakukan secara univariat dan bivariat menggunakan uji Wilcoxon Signed Rank Test untuk melihat perubahan signifikan sebelum dan sesudah intervensi. Hasil penelitian menunjukkan adanya peningkatan yang signifikan pada ketiga variabel. Pengetahuan kategori baik meningkat dari 65,2% menjadi 95,7% setelah penyuluhan. Sikap kategori baik meningkat dari 65,2% menjadi 91,3%, sementara tindakan baik meningkat dari 56,5% menjadi 91,3%. Uji Wilcoxon menunjukkan nilai p-value pengetahuan = 0,020, sikap = 0,034, dan tindakan = 0,005 (p < 0,05), yang mengindikasikan bahwa penyuluhan berpengaruh signifikan terhadap peningkatan ketiga variabel tersebut. Media leaflet yang digunakan dalam penyuluhan turut membantu responden memahami materi secara lebih mudah dan berulang. Penelitian ini menyimpulkan bahwa penyuluhan kesehatan efektif dalam meningkatkan pengetahuan, sikap, dan tindakan masyarakat terkait pencegahan kolesterol. Rekomendasi dari penelitian ini adalah perlunya kegiatan penyuluhan rutin oleh tenaga kesehatan, peningkatan akses masyarakat terhadap informasi kesehatan yang mudah dipahami, serta penerapan gaya hidup sehat secara berkelanjutan untuk menekan risiko kolesterol tinggi di masyarakat pedesaan.

Abstract

Learning Artificial Intelligence (AI) concepts at the vocational high school level often presents challenges, particularly in understanding procedural algorithms such as K-Nearest Neighbor (K-NN). Students frequently experience difficulties in calculating distances, selecting the optimal value of k, and determining classification results accurately and efficiently. This study investigates the effect of a chatbot tutor designed for K-NN practice on students’ speed and accuracy in solving AI problems. A quasi-experimental design with a pretest–posttest control group model was employed. Sixty students from a vocational high school majoring in Software Engineering were divided into an experimental group receiving chatbot-assisted practice and a control group receiving conventional instruction. Data were collected through validated K-NN problem-solving tests and task completion time measurements. Statistical analysis using paired and independent sample t-tests revealed that the experimental group demonstrated significantly faster completion times and higher accuracy scores compared to the control group (p < 0.05). The effect size indicated a moderate to high practical impact. The findings suggest that chatbot-based tutoring can enhance both efficiency and precision in learning K-NN algorithms. This study contributes empirical evidence supporting the integration of chatbot tutors into Artificial Intelligence instruction in vocational education to improve problem-solving performance.

Abstract

This study aims to identify the perspectives of first-year students in the French Language Education Study Program, Faculty of Languages and Arts, Universitas Negeri Jakarta, regarding the use of digital flashcards in learning French reading skills at the A1 level. The research was conducted in the French Language Education Study Program of the Faculty of Languages and Arts at Universitas Negeri Jakarta in 2025. The population of this study consisted of first-year students enrolled in the reading skills course (réception écrite), with a total sample of 62 students. The research instrument was a 20-item Likert-scale questionnaire to measure students’ perceptions, needs, and experiences regarding the use of learning media in reading activities. The data were analysed using a quantitative descriptive method, and the percentage of students’ responses to each statement was calculated. The results show that 95% of students are aware that reading skills are an essential competence in learning French. However, 71% of students reported difficulties understanding French texts, particularly with new vocabulary, sentence structure, and overall comprehension. In addition, 89% of students stated that they need support for learning media to facilitate the reading process, and 87% reported feeling more helped when the material is presented through visual media.““Furthermore, 92% of students indicated that digital flashcards are needed for French language learning. Although the use of digital flashcards is still relatively rare in classroom practice, students demonstrate very positive perceptions of this medium. Therefore, the development of digital flashcards can be considered a relevant and potential solution to support the learning of reading skills for beginner-level French learners (A1).
