Abstract

Environmental problems included biotic, abiotic, and social problems, therefore, to overcome them, various scientific disciplines are needed as well as the characteristics of environmental science itself. As consequences of population growth, industrial development, and technological progress, environmental problems are more complex. Therefore, appropriate research methods are needed to overcome new problems that arise as a result of these developments. UNEP recommends a research method called the DPSIR (Driving force–Pressure–State–Impact–Response) model that can describe the interactions between various environmental and social factors. This method has been applied as an approach to analyzing environmental problems in many countries around the world, including Indonesia. The Ministry of Environment and Forestry (KLHK) and some researchers in Indonesia have also applied the DPSIR method to assess environmental status both nationally and regionally. So far, the DPSIR method is still quite well applied to analyze environmental problems, although some scientists highlight the need for this method to be supplemented with other models to improve results.

Abstract

Water use efficiency (WUE) is an essential subject in drought-restricted agricultures. Physiological parameters can be used to understand plant efficiencies in water usage. This research aimed to understand the physiological characteristics of 30 Indonesian sorghum accessions (Sorghum bicolor (L.) Moench), which indicate WUE and drought tolerance. Field research was conducted at Cibinong Science Center, National Research and Innovation Agency (BRIN) using Randomized Block Design with 30 sorghum accessions in 3 replicates. Experimental parameters included photosynthetic photon flux density (PPFD), stomatal conductance (GSW), photosynthetic (A) and transpiration (E) rates, and Leaf Area Index (LAI). The WUE was measured using four different approaches: instantaneous WUE (A:E), intrinsic WUE (A:GSW), and the relation between the biomass dry weight (BDW)/A and BDW/E. Based on WUE measurements, we concluded that sorghum accessions could be clustered into five groups, from the most efficient to inefficient water use. We also found that in some cases, WUE based on single leaf measurement had a positive correlation with WUE based on biomass, indicating its sufficiency in determining WUE status. The inconsistencies may be due to different sorghum physiological characteristics regarding gas exchange due to external stimuli (PPFD).
