Tidal flood, erosion and sedimentation are serious problem in Nord of Central Java-Indonesia. Many spots experience functional coastal land disturbance. This research, therefore, is aimed to identify coastal problems and analyze the causes and bring up some alternative engineering solution. The research method used is to hold a survey at the damaged location of the coast, to analyze the characteristics of hydrooceanography and spatial measurement and the alternative engineering solution. The total of coastal line of the studied coast based on Geographical Information System is 427,01 kilometers, covering 13 regencies and towns in Central Java Province. The dominant problem found at the studied location are tidal flood, erosion, estuary closing, sedimentation and sea water intrusion caused by the impact of coastal area development, mangrove plant cutting, and coral destruction. The most infrastructure built is port facilities without assisting building for anticipating impact. Mangrove plant cutting is due to extension of fish pool. Coral materials are exploited and traded. Generally the alternative engineering solution is protection with hard structure (groins, seawall), and with soft structure by replanting mangrove plants. Part of the alternative solution has been implemented and evaluated.
