Abstract

Manufacturing Company is a sample of this study, the dependent variable used in this study is a binary variable, namely whether the company is in financial distress or non-financial distress. Hypothesis testing uses binary logistic regression (Binary Logistic Regression) because the dependent variable is a combination of metric and non-metric (nominal). The model used is the Altman Z-Score model, Springate S-Score, Grover G-Score, Zmijewski X-Score, and univariate models. Of the five models, the best model is the Springate S-Score with a Nagelkerke R2 value of 0.582. the second is, Zmijewski X-Score with a value of 0.227 and the third best is the Univariate Model with a value of 0.042. Of the three best models, namely the Springate S-Score, Zmijewski X-Score and the Univariate Model. The implementation is that the ratios in these models are very important to be considered by companies as a sensitivity tool so that companies do not experience financial distress. ratios that are often used are ratios related to the company's ability to manage and produce net working capital, sales, debt and ability to generate profits from sales and profits from assets.

Abstract

Generation Z is currently entering the working world. However, there are reports that generation Z is uninterested in working for the government agency, thus government agencies need to understand the principles and values held by this young generation,  so as not to lose potential human resources in the future. Through an analysis of the work values dimensions, this study aims to identify the career preference of generation Z. The respondens in this study were 102 generation Z students at Putra Bangsa University, Indonesia. Data was obtained by distributing questionnaires and then analyzed with descriptive statistics via SPSS. The results show that the majority of generation Z students prefer to work at State-Owned Enterprises or Badan Usaha Milik Negara (BUMN) rather than being civil servants when they graduate from university. The work values believed by the group who want to work in BUMN and the group who want to become civil servants are explained in the results of this study. The results of this study provide an overview of the work values that are the principles of generation Z, so that it can help organizations understand the characteristics of generation Z in the workplace.
