How Perceived Organizational Support for Environment Serves a Mechanism to Enhance Environmental Performance From Employee Perspective in Health Sector of Indonesia

Abstract: Our study investigates the role of Green human resource management (GHRM) practices on the individual environmental performance of employees (IEP) as well as the mediating role of perceived organizational support (POS) in the health sector in Indonesia. Data was collected using a questionnaire that was shared with 310 nurses working in Indonesian as respondents. SmartPLS 3 software is used to analyze data by adopting the PLS-SEM approach. The research findings reveal a strong and positive relationship between the dimensions of GHRM practices such as Green Employee Involvement (GEI),  Green Management Performance (GMP), and Green Training (GT) on the individual environmental performance of employees in Indonesia's health sector. Furthermore, we also found an indirect effect of GHRM practices on employees' environmental performance through perceived environmental support from the organization company. Based on our study, we suggest Institutions and organizations in Indonesia's health sector concern implement GHRM practices to improve their employees' individual environmental performance. Specifically, our study extends the previous literature by exploring the relationship of GHRM practices with individual environmental performance using perceived organizational support (POS) as a mediating variable.

Forecasting Periodic Series to Reduce the Bullwhip Effect in Palm Oil Commodity Supply Chain System in PTPN VII, Lampung, Indonesia

Abstract:

The purpose of this study was to investigate whether the bullwhip effect (BE) occurs in CPO production  at PTPN VII Unit Bekri, Lampung. Moreover, we make forecasting for the demand of CPO Products using the Double Moving Average (DMA) method and the Double Exponential Smoothing (DES) method as well as comparing the forecast result from both of these methods based on the lowest Mean Absolute Error (MSE) and Mean Absolute Percentage Error (MAPE) values. The monthly data on CPO production and sales for the period 2019 – 2021 is used for forecasting demand of CPO products. Our result shows that the initial BE value (1.08) is higher than a parameter value (1.04) and it indicates occurs BE on CPO production in PTPN VII Unit Bekri, Lampung. Furthermore, our findings also found that the value of MSE and MAPE from using the DMA method is lower than the DES method. Based on the results of this study, it is also expected to contribute references related to the application of forecasting methods in order to minimize BE. The DES method can be used to minimize BE that occurs in PTPN VII bekri units, based on the results of the analysis the DES method can reduce the BE value by 0.09.
