Abstract

AbstrakHipertiroid merupakan sindroma klinis yang terjadi bila jaringan terpajan dengan jumlah hormon tiroid yang berlebihan karena hiperaktivitas kelenjar tiroid. Hal tersebut akan memberikan efek spesifik terhadap metabolisme sel, termasuk metabolisme lipid. Perubahan metabolisme lipid pada hipertiroid akan menimbulkan manifestasi klinis seperti gangguan mood, peningkatan perilaku depresi, dan peningkatan perilaku agresif. Dalam diagnosis pasien hipertiroid, pemeriksaan kadar FT4 dan TSH serum menjadi tes fungsi tiroid yang tepat. Penelitian ini bertujuan untuk melihat bagaimana hubungan antara kadar FT4 dan TSH serum dengan profil lipid darah pada pasien hipertiroid. Penelitian ini menggunakan data deskriptif di Instalasi Rekam Medis RSUP dr. M. Djamil Padang pada bulan Februari 2013 sampai Juli 2013. Data yang dikumpulkan berasal dari catatan rekam medik pasien hipertiroid yang dirawat inap berjumlah 21 orang dengan teknik total sampling. Analisis bivariat digunakan untuk melihat hubungan antara kadar FT4 dan TSH serum dengan profil lipid darah. Dari sampel yang ada diperoleh data rerata profil lipid, yakni: 143,33 mg/dl (kolesterol darah total); 42,06 mg/dl (HDL); 85,45 mg/dl (LDL); dan 77,19 mg/dl (trigliserida). Berdasarkan uji korelasi regresi, terdapat korelasi negatif antara kadar FT4 dengan kadar kolesterol darah total, HDL, dan LDL, tetapi tidak terdapat korelasi antara kadar FT4 dengan trigliserida. Hubungan antara kadar TSH serum dengan kolesterol darah total dan LDL mempunyai korelasi positif, tetapi tidak terdapat korelasi antara kadar TSH serum dengan HDL dan trigliserida. Penelitian ini memperlihatkan bahwa sebagian besar profil lipid darah mempunyai korelasi dengan kadar FT4 dan TSH serum, kecuali trigliserida.Kata kunci: kadar FT4 dan TSH serum, profil lipid darah, hipertiroidAbstractHyperthyroidism is a clinical syndrome that occurs when tissues are exposed by excessive amount of thyroid hormones due to thyroid gland hiperactivity. It has spesific effects on cell metabolism, including lipid metabolism.L ipid metabolism disorder in hyperthyroid will inflict clinical manifestation; such as mood disorders, depression, and increased aggressive behavior. In diagnose patient with hyperthyrodism, FT4 and TSH serum level test are the appropriate thyroid function test. The objective of this study was to determine relationship between FT4 and TSH serum level with blood lipid profile in patient with hyperthyrodism. This studies got the descriptive data in Medical Records Departement of RSUP dr. M. Djamil Padang from February 2013 to July 2013. Data of 21 hyperthyrodism patient were got with total sampling technique. Bivariat analysis is used to examine the relationship between FT4 and TSH serum level with blood lipid profile. From the sampel was obtained data of profile lipid average, that is 143,33 mg/dl (total cholesterol); 42,06 mg/dl (HDL); 85,45 mg/dl (LDL); dan 77,19 mg/dl (triglycerides). Based on the regression test, there was negative correlation between FT4 level with total cholesterol, HDL, and LDL, but, there wasn’t correlation between FT4 level with triglycerides. The relationship between TSH serum level with total cholesterol and LDL had positive correlation. But, there isn’t evidence of correlation between TSH serum level with HDL and triglycerides. This study shows that the most of blood lipid profile has correlation with FT4 and TSH serum level, except triglycerides.Keywords: FT4 and TSH serum level, blood lipid profile, hyperthyrodism

Abstract

Plasma cutting is a widely used process for cutting metal plates using a high-temperature electric arc. Conventional systems are manually operated, which limits cutting precision and efficiency. To address this, a CNC plasma cutting machine was designed with a focus on structural reliability. The machine frame was designed to support automated motion along X, Y, and Z axes, enabling precise plasma head movement. The overall machine dimensions are 3000 mm × 1500 mm × 1000 mm, with a work area of 2400 mm × 1200 mm. Structural components were modeled using CAD software and analyzed using the Finite Element Method (FEM) to evaluate deformation, stress distribution, and safety factors. The structural analysis revealed maximum displacements of 4.14 µm and 3.83 µm in the X and Y units, respectively. The highest von Mises stress was found to be 56.57 MPa on the X unit and 50.19 MPa on the Y unit. The minimum safety factors were 4.41 for the X unit and 2.36 for the Y unit, indicating a safe and robust structural design. The results confirm that the designed machine frame meets mechanical integrity requirements for automated plasma cutting operations. The low deformation and acceptable stress levels ensure cutting accuracy and operational reliability. This design may serve as a foundation for future improvements or implementation in manufacturing environments.
