Abstract

Kidney failure is a critical condition that requires intensive monitoring of the patient's survival. This study aims to analyze the survival of kidney failure patients using a survival analysis approach with Nelson-Aalen cumulative hazard function estimation and the Log-Rank Test. The data used consisted of 106 patients with kidney failure who underwent hospitalization for 35 days, with characteristic variables including disease severity (chronic or acute), sex, and age group (≤ 50 years or > 50 years). The results of Nelson-Aalen's estimation showed that patients with acute conditions, male and > age 50 years had a visually higher risk of death. However, the results of the Log-Rank test showed that there was no significant difference in survival function between the three categories (p-value > 0.05). These findings suggest that although there are visual indications of a difference in risk, statistically, these clinical characteristics have not had a significant effect on patient survival in the observation period. This study suggests the need for further studies with data and a broader duration of observations to gain a deeper understanding.

Abstract

In Biology class, students face problems understanding the material that seems abstract to observe, such as biological system mechanisms. This study was aimed at developing interactive learning media products based on animated videos using the Unity application in the excretory system lesson for eighth grade and determine the response of teachers and students. This study adapted the ADDIE model to develop interactive learning media. The steps in this study are analysis, design, development, implementation, and evaluation. The findings indicate that the content quality and media quality percentages are 83.35% (very feasible category) and 92.75% (very viable category) respectively. Furthermore, students scored the product in average 84.5% (very feasible category). Meanwhile, the science teachers assessed the product in average 91.7% (very viable category) from the teachers. The results of the Wilcoxon signed-rank test also showed a significant difference between the students' pretest and posttest results. It can be concluded that the interactive learning media based on animated videos can be used as an alternative learning media in the excretory system lesson for eighth grade students.
