Abstract

Latar Belakang: Fraktur merupakan gangguan kontinuitas tulang yang sering kali menimbulkan nyeri akut signifikan akibat kerusakan jaringan dan peradangan. Jika tidak ditangani, nyeri dapat menghambat proses penyembuhan dan meningkatkan stres fisiologis. Di RSUD Dr. H. Abdul Moeloek, angka kejadian fraktur masih tergolong tinggi, dan banyak pasien tetap merasakan nyeri meskipun telah diberikan analgesik. Kompres dingin merupakan salah satu manajemen non-farmakologis yang bekerja melalui vasokonstriksi untuk mengurangi aliran darah dan mematikan sementara saraf perasa nyeri. Tujuan: Penelitian ini bertujuan untuk menganalisis pengaruh pemberian kompres dingin terhadap penurunan tingkat nyeri akut pada pasien fraktur berdasarkan perbandingan skala nyeri sebelum dan sesudah intervensi di RSUD Dr. H. Abdul Moeloek Provinsi Lampung Tahun 2026. Metode: Penelitian ini menggunakan desain pre-experimental dengan pendekatan one group pre-test and post-test. Pengukuran tingkat nyeri dilakukan sebelum dan sesudah intervensi menggunakan instrumen Numerical Rating Scale (NRS). Hasil: Berdasarkan data prasurvei terhadap 10 pasien fraktur, rata-rata skala nyeri pasien menurun dari skala 7 (nyeri berat) menjadi skala 5 (nyeri sedang) setelah diberikan terapi kompres dingin. Literatur pendukung juga menunjukkan adanya pengaruh signifikan secara statistik dengan nilai p = 0,001 (< 0,05). Kesimpulan: Pemberian kompres dingin efektif dalam menurunkan intensitas nyeri akut pada pasien fraktur. Intervensi ini disarankan untuk diintegrasikan ke dalam Standar Prosedur Operasional (SPO) manajemen nyeri di rumah sakit.

Abstract

Starch-based bioplastics are promising sustainable alternatives to petroleum-based plastics; however, their limited mechanical strength and stability restrict broader packaging applications. This study investigates the influence of polyvinyl alcohol (PVA) content on the structural and functional properties of starch-based bioplastic films reinforced with chitosan and microcrystalline cellulose (MCC). Films prepared by solution casting with varying PVA compositions were characterized in terms of density, mechanical properties, thermal stability, biodegradation behavior, antibacterial activity, and structural features. Increasing PVA content produced denser film structures with improved tensile strength and thermal stability, while elongation at break reached its maximum at the intermediate formulation, indicating a strength–ductility trade-off. The control film exhibited antibacterial inhibition zones of 12.6 mm against Staphylococcus aureus and 8.8 mm against Escherichia coli, with activity decreasing at higher PVA content. These findings demonstrate that adjusting PVA composition effectively tailors the multifunctional performance of starch-based bioplastic films for sustainable packaging applications.

Abstract

Blowout Preventers (BOPs) are critical safety devices in drilling operations and operate in abrasive, high‑pressure environments that accelerate wear and failure. This study applies two Non‑Destructive Testing (NDT) methods, Liquid Penetrant Testing (LPT) and Magnetic Particle Testing (MPT), to identify surface defects on RAM BOP components, and integrates finite‑element‑based crack propagation simulation to assess the risk of further damage. LPT was applied to coated/non‑ferromagnetic parts, while MPT was used for ferromagnetic components, referencing ASME Section V acceptance criteria. Inspections revealed defects including a 4.9 mm crack on the piston shaft and pitting corrosion (≈0.8-5.3 mm) on several parts (e.g., cavity upper, housing). The simulation, with 3000 psi operating pressure and an initial flaw (l = 3 mm; h = 1 mm; r = 0.6 mm), predicted stress concentration at the crack tip (up to ~141 MPa) and potential growth toward ~7.9-11.7 mm if unrepaired. Recommended actions include re‑welding cracked regions and polishing minor scratches/pitting, combined with periodic NDT for early detection. The integrated NDT-simulation workflow supports proactive maintenance, enhances operational safety, and mitigates failure risk.

Abstract

This study examines the corrosion resistance performance and failure mechanisms of a hybrid coating system based on castor oil and nano-SiO₂ with three particle size variations (20 nm, 100 nm, and 500 nm) applied to ASTM A36 steel. We compared uncoated samples with three coating variants to evaluate the effect of nano-SiO₂ size on corrosion resistance and damage development. Coating resistance was tested using potentiodynamic polarization, FTIR analysis, corrosion morphology characterization, and coating thickness measurements. Compared to uncoated steel, the formulation with 100 nm nano-SiO₂ provided the greatest improvement, with a three-order decrease in corrosion current density (icorr = 1.33×10⁻⁸ A/cm²) and a shift in corrosion potential toward a more positive direction, accompanied by stable surface morphology and minimal chemical changes. This effectiveness is achieved through homogeneous particle dispersion, which produces a dense barrier structure and tortuous diffusion pathways without a significant increase in thickness. Failure mechanism analysis shows that small particle sizes (20 nm) trigger porous barrier breakdown due to nano-silica aggregation, while large particles (500 nm) cause coating cracking and localized pitting due to sedimentation and excessive thickness. In contrast, the 100 nm size stabilizes the passive film and suppresses pit initiation. These findings confirm that controlling the size and dispersion of nano-SiO₂ not only improves corrosion resistance but also determines the dominant failure pathway in coatings. This research contributes to the development of sustainable bio-nano coatings for structural applications by highlighting the importance of microstructural reinforcement and understanding failure mechanisms in designing high-resistance coating systems.

Abstract

This study investigates the structural performance of three stopper mounting designs for conveyor systems using finite element simulations in ANSYS Workbench. The analysis was conducted using a static structural method, where a vertical downward load of 103.43 N converted from the total weight of the stopper was applied to the structure, and fixed support boundary conditions were assigned at the mounting base. We compared the original design with two modified versions, including one reinforced with stiffening ribs. We evaluated each model under static loads by measuring total deformation, equivalent stress, elastic strain, and safety factor. Compared to the original design, MD 1 reduced total deformation by 88.42%, elastic strain by 53.04%, and equivalent stress by 30.72%, while increasing the safety factor by 0.94%. These improvements were achieved without significantly increasing material usage. The addition of stiffening ribs effectively directed internal forces, stabilized stress zones, and enhanced structural resilience. The original design, while functional, exhibited high deformation and uneven stress distribution that limited its suitability for precision-dependent operations. Reinforcing the geometry proved essential in achieving better mechanical performance and durability. This validates the use of local structural enhancement as a key strategy in mechanical design. The findings contribute to automation system development by highlighting the importance of local reinforcement in precision-oriented automation components.
