iv Preface When I was studying Environmental Planning Course in RUG, I was interested with Strategic Environmental Assessment (SEA). SEA could be said as Environmental Impact Assessment (EIA) applied at policies, plans, and it has been applied internationally. SEA could be applied as a complement for EIA in achieving sustainable development goal. Since Indonesia has no SEA experience at all, this new insight has triggered me to deeply study SEA. Thus, the focus on this research is exploring the possibility of implementing SEA for transport planning, which has a wide influence on environment, socio and economic aspects.
