Experimental factorial by two levels was conducted to 80 students which collected with cluster random sampling technique. Experimental learning strategy were accomplished two type strategies such Field Trip and Classical learning. While for simple effect using higher and lower the comprehension about physic of water body. Result of this research that are (1) there is significantly different between effect of field trip and classical learning on participation of bioregional conservation (F= 4,53; p < 0,01); (2) Students with higher comprehension about physic of water body, there is significantly different between effect of field trip and classical learning on participation of bioregional conservation (F = 4, 37; p < 0,01); (3) Students with lower comprehension about physic of water body, significantly different between effect of field trip and classical learning on participation of bioregional conservation (F = 4, 37; p < 0,01); and (4) there is interaction between environmental learning strategy and comprehension about physic of water body on participation of bioregional conservation (F =5,89; p < 0,01). Conclusion, to achieve participation of bioregional conservation with applied the environmental learning strategy will be taken attempts the comprehension about physic of water body. Keywords: Environmental Learning Strategy, participation of bioregional conservation, comprehension about physic of water body INTRODUCTION Rivers are the most important freshwater resource for people. Social, economic and political development has, in the past, been largely related to the availability and distribution of fresh waters contained in riverine systems. Physically, diverse of the river consist in size, geometry, substrat, sediment type, stage development, and climate (Nature Conservacy, 2015). The dynamic system of the rivers that continually adjust to natural and human caused changes for industry, agriculture, and domestic use. Rivers ranked highest using these criteria can be considered ‘high conservation aquatic ecosystems’ and can subsequently be targeted for more in-depth analysis and prioritisation. These aquatic habitats of high conservation value should facilitate strategic policy development aimed at conserving most valuable rivers (Stewart, Barbara, 2011). While management of erosion and flooding requires considerable effort and cost. The view of river perspective known as bioregional system, where a river as long from upper water flow to ocean affect to biodiversity. 1 Magister Program, Population and Environmental Education, State University of Jakarta 2 Magister Program, Environmental Management, Pakuan University
