Abstract

River estuary is downstream part of the river that associated with the sea. The river water flowing from upstream to downstream will be wasted to the sea through the river estuary (Loloan). The water that flows in a river was a water surface due to rain, springs, groundwater and waste or household waste. This research will organize the Saba River estuary area in Buleleng Regency based on tourism environment, for water conservation.The whole Watershed that flows in Buleleng regency bali province drain its water towards the sea through the downstream river / estuary of the river. River estuary / Tukad Saba is one of the downstream located in Buleleng Regency with parennial type. where much of the flow is a rice field, river estuary area Saba has not laid out properly. It needs to be planned for area arrangement based tourism environment. River estuary is the water body area where the entry of one or more of the river to the sea, kedanau, dams, ocean or river to another larger. In coastal areas, river estuary deeply affected by inland water conditions such as freshwater and sediment flow. and sea water such as tidal, wave, and the influx of salt water inland. Depending on the location and the environmental conditions, estuaries may contain many ecological niches within a small area, and so is associated with high biodiversity. The results of measurements of water discharge in the river estuary Saba in the dry season of 0,156 m3/sec and in the rainy season amounted to 1,023 m3/sec. Potential water in the estuary of the Saba of 9.34 million m3/year can be used for the water industry (hotel) 1364 rooms, for domestic water 81.854 inhabitants, for a fish pond of 2 ha and 148 ha of irrigation water. Arrangement of estuary area of the river Saba of the environmental aspects of tourism can be implemented with the availability of hazard map, clean water can be met as needed, illumination walkways such street lights are designed appropriately, the opening of the circulation path effluent from the coast toward the riverbank and the construction of a jetty for the smooth of discharge flow of the river to the sea.
