“…Hydrodynamic condition has a significance role evoking the unstable abrasion and accretion along Banten Bay coast. According to Rahmawan et al (2017) during 1991-2013, the abrasion reached 384.15 hectares and the accretion reached 425.50 hectares. The erosion is faster when the mining activity has been occurring (2003)(2004)(2005)(2006)(2007).…”

“…One of the worst problems occurred in Banten Bay is sand mining activity. It started from 2003 and stopped for a while in 2013, resulting in altered morphology around Lontar Village coast (Rahmawan et al, 2017). It also influences Ciujung delta formation.…”

“…In addition, the current direction is slightly different compared with the newer simulation, located in the west part within the bay where the speed is decline. That declination is caused by a rapid sediment deposition within the bay resulted by sand mining in the bay mouth triggering the unstable sediment transport in the surrounding (Rahmawan et al, 2017).…”

“…Those small islands should have a role influencing longshore current profile within the bay. In addition, some small islands run into erosion and sedimentation impacted by sand mining in the northern of the bay triggering the unstable transport sediment in and out of the bay (Rahmawan et al, 2017).…”

Hydrodynamical condition of Java sea as a part of Indian-Pacific throughflow system which is influenced by monsoon will affect the condition of Banten bay such tidal current. Bordered by Java sea makes Banten bay preoccupied with fisheries and shipping activities, so the information of current pattern e.g. tidal current is very necessary. This study aims to simulate the tidal current pattern using flow model fm as a numerical approach. Two-dimensional hydrodynamic model was employed to perform the simulation of tidal current. Model was validated by using current and tidal observation data which was taken on September 2015 and April 2016. The result shows that the current moved southwestern toward the land during high neap and high spring tidal conditions which ranged 0 – 0.142 m/s at the first transitional monsoon and 0-0.153 m/s at second transitional monsoon. During low spring tidal condition for both transitional monsoon, the current flowed northwestward on west side and northeastward on east side within the bay which ranged 0 – 0.137 m/s and 0 – 0.127 m/s respectively. The hydrodynamic conditions of Banten Bay are severe different between 2 transitional seasons, especially for the current speed and direction. It induces a different transport mechanism, resulting the unstable accretion and abrasion along Banten Bay coast.

“…Sand mining legally since 2003 started from Lontar Village and was temporarily stopped in 2013. Sea sand mining which has lasted for more than 10 years has resulted in morphological changes as evidenced by an increase in the incidence of abrasion and accretion in the northern region of Banten [11].…”

Seagrass meadows are important ecosystem due to their structural and functions role as a place for various nutrient cycles, feeding area, and breeding for a variety of marine species. Increased human activity in the form of shipping, sand mining, reclamation, and the development of tourism sector is reported causing disturbed seagrass condition. Therefore, spasio-temporal monitoring of the seagrass condition is important to understand the relationship between the seagrass condition and the stresses from human activity. This research was conducted to analyze the change of seagrass distribution in Banten Bay and its relation with human activity using multi temporal Landsat data from 2008 to 2018. Landsat data is processed using Depth Invariant Index method and classified using Maximum Likelihood with field data. The results of this study indicate a reduction of 74,28 ha seagrass area in the Banten Bay from 2008 to 2018 due to increased human activity.

Coastal erosion and accretion have altered the shorelines of various Indonesian coastal areas, endangering the lives and livelihoods of coastal populations. Damage to beaches in coastal areas affects the community’s daily activities, the transportation system, industry, and trade, as well as the environment and public health. Based on this occurrence, the initial stage of disaster management study resulting from coastal damage is to identify the coast’s vulnerability to threatening harm. To assess coastal vulnerability, field observations and measurement from the research location were carried out to obtain visual damage observation, land use, lithology, tidal range, and beach slope. Coastline data from satellite imagery and wind data from the government agencies were carried out to obtain the rate of shoreline change, width of damage, length of damage, and wave height. The purpose of this research is to look at changes in the coastline of Serang, Banten Province, and analyse the amount of beach damage to set priorities for coastal management. The beaches explored were Karangantu Beach, Domas Beach, Lontar Beach, and Tengkurak Beach. Karangantu Beach’s level of vulnerability is classified as very high, so dealing with it is a top priority. Domas and Lontar Beaches are extremely vulnerable, so dealing with them is a key priority. Tengkurak Beach has a moderate level of vulnerability, hence the priority for managing is rather high. This can be utilized as a model for overcoming coastal damage in Serang District, Banten Province, by constructing coastal protection buildings based on the shore’s vulnerability and management priority.
