Abstract

Penyakit ginjal kronik (PGK) stadium lanjut sering disertai komplikasi anemia dan hipertensi yang memperburuk kualitas hidup serta meningkatkan risiko morbiditas. Laporan kasus ini bertujuan menggambarkan manifestasi klinis, penatalaksanaan, dan respons terapi pada pasien anemia et causa PGK stadium V yang menjalani hemodialisis rutin. Kasus ini melaporkan seorang perempuan 65 tahun dengan keluhan lemas, sesak, mual, pucat, dan edema tungkai, serta riwayat hemodialisis dua kali seminggu dan hipertensi. Pemeriksaan fisik menunjukkan konjungtiva anemis, peningkatan JVP, ronki halus minimal, dan edema pitting bilateral. Laboratorium awal menunjukkan anemia berat (Hb 5,55 g/dL), ureum dan kreatinin meningkat, serta laju filtrasi glomerulus sangat rendah. Pasien mendapat transfusi PRC, terapi medikamentosa, pengaturan diet, serta hemodialisis. Evaluasi pascaterapi menunjukkan peningkatan hemoglobin, penurunan ureum dan kreatinin, serta perbaikan tekanan darah, meskipun muncul hipokalemia pascadialisis. Kasus ini menegaskan pentingnya tatalaksana komprehensif meliputi koreksi anemia, kontrol tekanan darah, manajemen cairan, dan kepatuhan hemodialisis rutin untuk memperbaiki kondisi klinis serta mencegah komplikasi pada pasien PGK stadium akhir.

Abstract

A ship is a type of floating structure that is specifically designed to move on the surface of sea water. This structure provides the ability for the ship to carry out various functions, from transporting goods, carrying passengers, to carrying out various other maritime operations. The advantage of a ship lies in its ability to move stably and efficiently in the midst of various dynamic marine environmental conditions. The direction of the ship's movement is controlled by the steering system, which is a crucial component in maintaining the smoothness and accuracy of the ship's journey. This steering system consists of various elements, one of which is the Rudder Stock. Rudder Stock has a vital role in the steering system because it functions as a link between the steering and the ship's propulsion system. Inside the Rudder Stock, there is another important component, namely the Seal. The Seal has the main function of withstanding pressure during ship operations, so that it can prevent leaks that can damage the steering system and other mechanical components. To evaluate the performance of the Seal in withstanding pressure, a pressure analysis was carried out using a numerical method based on Computational Fluid Dynamics (CFD) software, namely ANSYS. The results of the study showed that the total working pressure on the Rudder Stock Seal reached 0.766 bar, which is the sum of the maximum hydrostatic pressure of 0.432 bar and the maximum fluid flow pressure of 0.334 bar.
