Abstract

This research aims to optimize the parameters in a weather prediction model using the Differential Evolution (DE) algorithm, with a focus on improving the accuracy of more reliable weather predictions. The main problems faced in developing weather prediction models are model complexity and uncertainty in parameterization. The DE method is used to adjust the complex parameters in the model, resulting in a significant improvement in weather prediction accuracy based on evaluation using observational data. The implications of this research are that it makes a valuable contribution to our understanding of parameter optimization in weather prediction, as well as improving our ability to predict atmospheric conditions more accurately and reliably.

Abstract

In the growing digital era, big data clustering becomes a major challenge in data analysis, especially with the well-known K-Means Algorithm that has limitations in dealing with large-scale data. This study aims to optimize the K-Means Algorithm for big data clustering with a computational distribution approach, to improve clustering efficiency and accuracy. We use the computational distribution approach to process data in parallel across multiple computing nodes, optimize memory usage, develop an intelligent cluster center selection algorithm, and optimize communication between nodes. The implementation of this optimization method successfully improves the efficiency and accuracy of big data clustering, reduces execution time and memory consumption. The practical implications include better business decision making and more effective marketing strategies based on more precise customer data analysis.

Abstract

Program pengabdian masyarakat dengan judul “Inovasi Edukasi Berbasis WhatsApp sebagai Upaya Peningkatan Partisipasi Keluarga Berencana yang Berwawasan Budaya Lokal dan Konservasi Sosial di Desa Sukamulya”  di Desa Sukamulya berfokus pada peningkatan partisipasi program KB melalui edukasi digital berbasis WhatsApp. Survei awal mengungkap hambatan utama berupa pandangan konservatif, keterbatasan informasi, dan minimnya pendampingan langsung. Implementasi grup WhatsApp yang melibatkan kader, tokoh masyarakat, dan keluarga muda memungkinkan penyampaian materi interaktif yang disesuaikan dengan budaya lokal. Evaluasi menunjukkan peningkatan pengetahuan peserta dari 48% menjadi 78% (kenaikan 30%) serta meningkatnya akses informasi dan komunikasi dengan tenaga kesehatan. Pelaksanaan program menghadapi beberapa kendala, antara lain keterbatasan akses teknologi bagi sebagian warga, perbedaan tingkat pemahaman yang menyebabkan penyerapan materi kurang merata, kesibukan peserta yang mengurangi konsistensi keikutsertaan, serta keterbatasan kapasitas kader dalam menangani pertanyaan kompleks. Meski demikian, program terbantu oleh dukungan pemerintah desa dan tenaga kesehatan, antusiasme masyarakat, ketersediaan teknologi bagi mayoritas warga, serta keterlibatan aktif kader dan tokoh masyarakat yang memperkuat kepercayaan dan mempermudah adopsi edukasi digital. Secara keseluruhan, inovasi berbasis WhatsApp terbukti efektif dalam memperluas jangkauan edukasi KB dan meningkatkan kesiapan masyarakat dalam menerima informasi kesehatan reproduksi.

Abstract

Background: The prevalence of anemia among pregnant women in Sukamulya Village has reached 60%, which is considerably higher than the provincial and national rates, indicating the need for educational and sustainable interventions. This community service program aimed to improve knowledge and preventive behaviors related to anemia through culturally based nutrition education and local food empowerment utilizing the SEHATI Digital Education innovation. Methods: This study employed a community service (PkM) program approach with a pre–post test design involving 60 participants (30 pregnant women and 30 posyandu cadres). The intervention included cadre training, education sessions for pregnant women, interactive modules, Sundanese-language educational videos, and a mobile-based digital application. Results: The implementation of Digital SEHATI increased pregnant women’s knowledge scores regarding anemia, iron (Fe) tablet consumption, and the utilization of local foods, from a mean pre-test score of 58 to 79 on the post-test (±36% increase). These findings indicate that the SEHATI digital education media has the potential to enhance health education outcomes compared to conventional approaches and support the establishment of the “Ibu Hamil Sadar Gizi Sukamulya (ISGS)” group as a platform for program sustainability. Conclusion: Technology-based nutrition education, combined with local food empowerment, effectively improved knowledge, health behaviors, and community capacity to prevent anemia among pregnant women.
