Coastal degradation can be determined as mangrove destruction and water quality degradation. Erosion and accretion are the impacts of mangrove destruction in coastal areas. Ecosystem condition and coastal environment destruction were analyzed in Tangerang coastal areas. Soil, mangrove vegetation, and water quality analysis were carried out in this study. Soil quality was analyzed descriptively. Mangrove vegetation and water quality were analyzed with the Important Value Index and STORET Index, respectively. The results indicated that the coastal of Tangerang is damaged both in terms of mangrove and water quality. The causal analysis showed that the damage to the coastal environment in Tangerang is largely influenced by the high amount of plastic, domestic, and industrial waste. Management recommendations that can be carried out on the coast of Tangerang are silvofishery management and mangrove planting right behind the wave breaker.

Jor Bay in East Lombok - West Nusatenggara is a small bay system characterized by a common pool resource, in which found a contestation of utilization among resources users. Even though the bay has been managed by a local institution, namely Lembaga Pemangku Awiq-awiq Teluk Jor (LPATJ), the role and perform of institutions in managing the bay is still very low. To ensure the sustainability of the bay, the need to converge the different resource users’ interests by balancing utilization to accommodate economical, ecological and social dimensions. This study aimed to assess the sustainability status of bay management and design future sustainable bay management strategies. To measure the sustainability status, we used a sustainability index intended to develop to bay ecosystem form. The current sustainability status of Jor Bay management showed a moderate level. The institutional dimension provides the greatest sustainability value, while the lowest degree shows in the ecological dimension. The governability of Jor Bay management shows low institutional interaction, limited scale (local), minimal initiative and low willingness to cooperate among elements. For this reason, the ICM (integrated coastal management) based management mechanism needs to be strengthened to ensure the functioning of the Jor Bay management system.
