Abstract

The development of Ambon city is centered around Ambon Bay. As the major area of marine and social activities, changes occurred directly affect to seawater degradation. Sedimentation is the main issue that has been occurring. Marine ecosystem can be potentially hampered by the high rate of sedimentation in the Inner Bay of Ambon (TAD). This study aimed to determine the distribution of sediment volume within the bay. Bathymetry of TAD was surveyed using transducer (Echosounder Echo track CVM Teledyne Odom Hydrographic Single Beam), which the depth of certain position was connected to GPS to record all the position data accurately. The field data are then analyzed spatially modelled in the form of 2D and 3D maps, overlaid with the past bathymetry data to calculate the bathymetry alteration and sediment volume estimation during 2014-2016. The depth of TAD in 2014 ranged between 0 – -42 meters, while, in 2016 the water depth slightly changed to 0 – -44 meters. The reduction of the water depth is observed in the 25 – 125 m from shoreline, where the bed thickness changes observed ranging from 0.1 - 1.4 m. Total volume of sediment augmentation reaches 13,236,182 m3 that covers about 67.67 Ha. Tidal current, that ranged averagely from 0-1.2 m/s, has a tremendous influence on sediment transport in TAD. The bay mouth, that is a semi-enclosed enclosed area, triggers sediment accumulation due to the weak tidal current transport. If ongoing, these conditions may endanger the environment and biota survival ability.

Abstract

An appropriate foreshore management should take into account coastal processes based on physical and biological features of the particular coastal environment. This study aims to determine the coastal landform and its instability and susceptibility through satellite study, thematic map, and groundtruth checking. The coastal landform of Pati is typified by the muddy coast with ~1 km tidal mudflat moving seaward and coastal plain moving landward. Mangrove ecosystem, mainly Avicennia, intermittently occurs along the coast of Pati resting on muddy substrates where tributaries drain off water from the hinterland. The coastal plain is largely occupied by salt and/or fish ponds. Considering the geological condition, coastal characteristic, and oceanographic processes, the coast of Pati has medium to high-risk level of landform changes with shoreline changes greater than 1 m/yr and 5 to 10 yearly coastal inundation driven by the erosion and sedimentation. The study provides insight in recognising time and space scale of an indicative risk of landform changes and its driving processes for the coastal management and planning purposes.

Abstract

Mangrove forests are tropical coastal vegetation communities, which has the ability to grow in coastal area with tidal and muddy environment. Several functions of mangrove forest such as ecological functions can be used for coastal protection, trapping sediment and strengthen the coastal ecosystems. Coastal waters in Dompu Regency, West Nusa Tenggara have natural mangrove ecosystem with a huge potency and advantages to the region. This study aimed to understand the condition of mangrove ecosystem based on satellite image analysis of Landsat 8 Operational Land Imager (OLI) in 2014 and assess the potency, information related to the utilization by community. Data collection in this study were combined from satellite imagery interpretation with interview and questionnaires. The results showed that the mangrove forest extent in Dompu Regency Coastal Waters were about 90,631 ha with uniformity index 0.68 (medium uniformity). Two mangrove species were found in the region namely Rhizopora stylosa and Rhizopora apiculata and used by the community for several purposes such as firewood, natural coastal protection from tidal, waves and abrasion, also for crabs and fish spawning ground.

Abstract

Ornamental coral is one of the trading commodities targets with high demand in all of the world because of its color and unique shape.  Various types of ornamental corals are usually found in a specific area and out of reach, where one of them situated in water depth that it so difficult to find. West Nusa Tenggara Province is known as one of the ornamental coral suppliers that has not been touched much by research related to the existence of ornamental coral natural resources. This study aims to obtain preliminary data on the existence of ornamental coral, especially in Saleh Bay waters. Observations carried out from 6 to 11 May 2015 at 6 locations, determined based on distance from the mainland with respective representation, which divided into categories such as near, medium and far using the straight-line transect methods for coral reefs condition, while belt transect methods used for ornamental corals assessment. The results showed the health of coral reefs in good condition with the cover above 50% at all stations except station 4 (medium category), where Acropora coral species dominated at stations 5 and 6 (distant category). The bottom substrate dominated by coral fragments and dead corals with algae (DCA), which are found 28 genera of ornamental corals and considered as trade commodities such as Euphyllia glabrescens, Euphyllia cristata, Euphyllia ancora, Echinophora sp, Gonioporasp, Lobophyllia sp, Physogyra sp, Merulina sp, and Turbinaria sp. The research location can be used as a permanent study area for ornamental coral focus subject and as an indicator for sustainable ornamental coral management in the region.

Abstract

Pangandaran West Coast is the famous tourism site besides many tourisms offer in Pangandaran Regency. These white sand beaches provide beautiful sightseeing, water sports, tourism facilities, culinary and many other interesting things. In contrary, there were many erosion evidences found and building damage during the field research, in this area that may harm the nature its self and the population as well. The aim of this research is to map the coastal vulnerability in Pangandaran West Coast by integrating Smartline Mapping approach and CVI (Coastal Vulnerability Index). Thus, we map vulnerability parameters in two directions, along and cross the coastline, that consist of 10 parameters such as beach material, wave exposure, hinterland relief, berm feature, grain size, berm height, beach face feature, significant wave height, coastline changes, and residential area density. Finally, after the mapped parameters were scored and calculated using CVI formula, the result showed that vulnerability index in Pangandaran West Cost ranged from 16.43 to 129.9 which divided into 5 vulnerability classes; 1) Very low, 2) Low, 3) Moderate, 4) High, and 5) Very High.

Abstract

Tourism carrying capacity assessment for the protection of coastal area was applied to Tanjung Bira beach as an attempt to assess the optimum allowable number of visitors in accordance to the PAOT (people at one time approach) without damaging the surrounding ecological, social and cultural environments. The study shows that the Real Carrying Capacity (RCC) was 202 beach user/day and the Effective Carrying Capacity (ECC) was 117 beach user/day. Although there was a significant difference between Physical-Ecological and Social-Cultural Carrying Capacity, this study suggests that the Physical-Ecological Carrying Capacity or Real Carrying Capacity may be applied for ecosystem management, whilst the Social-Cultural Carrying Capacity or Effective Carrying Capacity (ECC) may be addressed when management objectives are tourists and beach user.
