Berdasarkan penelitian ini, didapatkan metode paling optimal adalah pada ekstraksi dengan hidrolisis asam pada suhu 4oC tanpa pengadukan yang menghasilkan rendemen 0,608% dengan kadar kolagen 2,4666% dari total hasil ekstraksi.

ABSTRACT
Chicken eggs are one of the food that most enjoyed by all people in the world. The consumption of eggs cause eggshell to be one of the biggest waste. However, the eggshell has its own benefits. The eggshell membrane, located right in the inner layer of the egg, contains collagen. Extraction needs to be done to obtain collagen from the chicken eggshell membrane. Hydroxyproline, a secondary amino acid, is a marker of collagen that needs to be derivatized using FMOC-Cl (9-Fluorenylmethoxycarbonyl-chloride) so, it could be analyzed with HPLC. This study aims to obtain an optimal method for collagen extraction from chicken eggshell membranes and its optimal method collagen content analysis using HPLC-fluorescence detector. Collagen extraction from the chicken eggshell membrane needs to be optimized to produce an optimal amount. Extraction optimization in this study was carried out with three parameters, which were, method (acid hydrolysis, enzyme hydrolysis, and mixture of both), temperature (4oC and 22-23oC), and the presence or absence of stirring. Based on this research, the most optimal method was extraction with acid hydrolysis at 4oC without stirring which results in 0,608% yield with collagen content of 2,4666%.

The dynamic nurse-patient relationship model has been used as a primary theory, providing nursing care approach into nursing practice which emphasizes the basic principles of critical thinking, client-centered and intervention-oriented approaches, and the use of evidence-based nursing intervention recommendations. The dynamic nurse-patient relationship model in residency practice establishes a decrease in cardiac output as the main nursing diagnosis in primary management patients and 30 other patients, with cardiac care as the choice of nursing intervention to optimize cardiac function and reduce cardiac workload. CAM-ICU as a diagnostic instrument has perfect reliability to assess delirium after cardiac surgery (100% sensitivity and 100% specificity). BHIS as an instrument to assess the risk of SSI events after cardiac surgery has moderate reliability (70% sensitivity and 67% specificity), meaning that BHIS needs to be developed by taking into account the factors related to SSI events.

 

Keywords: ida jean orlando, delirium, CAM-ICU, surgical site infection, cardiac surgery, low cardiac output, respiratory muscle training.
