Abstract

Sarkopenia merupakan kondisi degeneratif yang ditandai dengan penurunan massa dan kekuatan otot. Pengabdian ini bertujuan untuk mencegah sarkopenia melalui sosialisasi, edukasi, dan tindak lanjut pengukuran kekuatan otot pada masyarakat lansia di Kelurahan Randusari, Kota Semarang. Metode yang digunakan meliputi edukasi dan skrining kekuatan otot menggunakan alat electromyography sebagai indikator dini risiko sarkopenia. Electromyography merupakan alat ukur kekuatan kontraksi otot yang dapat digunakan untuk mengevaluasi kondisi otot. Proses screening sarkopenia diawali dengan identifikasi gejala melalui kuesioner, dilanjutkan dengan pengukuran kekuatan otot menggunakan electromyography sebagai indikator utama. Jika kekuatan otot menunjukkan nilai di bawah ambang batas, maka dilakukan evaluasi performa fisik, seperti kecepatan berjalan, dilakukan untuk menentukan tingkat keparahan. Berdasarkan hasil pemeriksaan, sarkopenia diklasifikasikan menjadi probable, confirmed, atau severe. Hasil pengabdian menunjukkan peningkatan pemahaman peserta tentang pentingnya pola makan bergizi dan aktivitas fisik rutin, serta terdeteksinya kelompok lansia dengan risiko penurunan fungsi otot yang kemudian diarahkan untuk tindak lanjut intervensi kesehatan. Program ini memberikan dampak positif berupa peningkatan kesadaran pencegahan sarkopenia dan penguatan kapasitas komunitas dalam menjaga kesehatan otot lansia. Rekomendasi pengembangan program ini adalah pelaksanaan monitoring berkelanjutan dan pelibatan lebih luas dari pemangku kepentingan setempat untuk meningkatkan efektivitas pencegahan sarkopenia di masa depan.

Abstract

Catheter-associated urinary tract infections (CAUTIs) are among the most frequent healthcare-associated infections, primarily caused by biofilm formation on catheter surfaces. This narrative review summarizes recent progress in antimicrobial urinary catheter development, focusing on substrate materials, functional agents, and fabrication strategies. Common substrates such as silicone, polyurethane, and thermoplastic elastomers provide biocompatibility and durability but require modification to achieve antimicrobial performance. Strategies including surface coatings (e.g., dip- and spray-coating, sol–gel, and layer-by-layer deposition), impregnation, composite blending, and hybrid designs have been investigated to deliver sustained antimicrobial release, antifouling resistance, and improved patient comfort. Coating-based methods enable localized control of active agents, while bulk modifications ensure durability despite surface wear. Emerging approaches highlight multifunctional systems that integrate antimicrobial, antifouling, and lubricious properties, supported by precision techniques such as nanostructured coatings and bioinspired surface engineering. By linking material selection with fabrication design, this review underscores the need for scalable and cost-effective strategies that combine long-term antimicrobial protection, mechanical integrity, and regulatory compliance. Future research directions include hybrid fabrication methods, sustainable manufacturing, and clinical translation to reduce the global burden of CAUTIs.

Abstract

The increasing demand for energy efficiency and lightweight transportation has encouraged the development of three-wheeled vehicles with optimized structural frames. This study evaluates the static and dynamic performance of three-wheeled vehicle frames using three high-performance materials Aluminium 7075-T6, S690 steel, and ASTM A572 HSLA 60 steel. Finite Element Analysis (FEA) was conducted with Altair HyperWorks to analyze stress distribution, deformation, safety factor, and natural frequency response. Static analysis results indicate that all materials are structurally safe, with S690 steel showing the highest stiffness and safety factor, while Aluminium 7075-T6 provides the greatest strength-to-weight efficiency despite higher deformation. ASTM A572 HSLA 60 offers moderate performance as a cost-effective alternative. Modal analysis reveals similar natural frequency ranges (1.5–3.2 Hz) across all materials, indicating that dynamic behavior is more influenced by geometry than material properties. The findings highlight the trade-off between strength, stiffness, and weight, suggesting Aluminium 7075-T6 as the optimal choice for lightweight and energy-efficient applications, while S690 steel is preferable for heavy-duty requirements. Overall, this research emphasizes a holistic approach in material selection for three-wheeled vehicle frames to balance mechanical strength, vibration characteristics, and energy efficiency.
