Abstract

The coastal area of Bengkulu City's Long Beach currently has natural, cultural and historical tourism and forest tourism. However, tourism in Bengkulu City's Long Beach is still not optimal in its management. In addition to increasing the diversity of tourism in the Long Beach area of the city of Bengkulu, alternative tourism is needed, namely marine tourism in the city of Bengkulu. To support the management of Bengkulu City Long Beach tourism area as a marine tourism area, it is necessary to manage and develop Bengkulu City Long Beach area in accordance with the conditions and pay attention to the potential of natural resources around the area.This study aims to examine and analyze how the strategy of managing the Long Beach area of Bengkulu city becomes an integrated and sustainable marine tourism area.

Abstract

This study aimed to analyze the pattern of sediment transport to the distribution of plankton and fishing ground in the estuary of KamparRiver. This study used survey methods, the study sample was obtained in the field are considered to represent the Kampar River estuary. Then the sampling results in the form of TSS, brightness, temperature, salinity, pH, flow velocity and plankton descriptively analyzed and discussed with reference to data interpretation method by using mathematical models (software mike21 ). The results showed the concentration distribution of sediment at the mouth of the Kampar River in east monsoon amounted to 8.76 million tons / day and in the west monsoon amounted to 7.64 million tons / day. A region prone to silting due to sediment transport is periodically southeastern portion Mendol. Based on the analysis modeling , plankton diversity index tends to be low in the study site so that the waters around the Mendol island excluding strategic area for fishing grounds it is indicated there has been a downward trend in plankton diversity index as the primary productivity . The existence of TSS may hinder the penetration of light that ultimately affect the photosynthetic plankton.

Abstract

Environmental change due to development processes, such as land clearing and construction of settlements and industries, are belived to cause disruotion of hydrologic conditions, increases level flow and flood peak flow. It happens because of the water absorption capacity at the land surface reduced. The menthod used is frequency analysis to determine the expected local rainfall on various repeated periods and the rain intensity, which are needed for flood flow calculations. The space utilization on economic sector in Sudirman Kota Dumai Rd., are likely to be increased from 2001, 2011, ro 2015. The result of the flood flow (Qp) analysis on 2015 shows tendency to increase on the following years (Qexisting kurang dari Qprediction). Where as the result of the flood flow (Qp) with catchment well is Qeksisting lebih dari Qscenario.

Abstract

Rangsang Island is home to more than 48,000 residents. Climate change has been a critical issue to the Island and threatened the existence of the inhabitants. This study is proposed to identify the zone of the coastal area of Rangsang Island which is vulnerable to climate change. By mapping coastal vulnerability index (CVI) of the island, it is expected to be a reference of local government in planning their spatial management. The method of this study was by a direct survey for collecting data of geomorphology, beach elevation, sea level rise, tidal fluctuation, significant wave height, and changes in the coastline. To determine CVI, each parameter is divided into 5 categories and given a value level: 1 for very not vulnerable, 2 for not vulnerable, 3 for moderate, 4 for vulnerable, and 5 for very vulnerable. The results show that most villages on the island are classified as highly vulnerable to climate change, namely 9 villages. Even 2 villages are threatened very high risk because the village has CVI more than 12.5. Only 6 villages whose territory has moderate vulnerability index. Vulnerability level of coastal Rangsang Island is strongly influenced by geomorphological variable and coastal elevation. In addition, the variable coastline changes and sea level rise also contributed to the vulnerability index of the Island.

Abstract

Siak river has a long history as a transportation lane in the east of Sumatera. From traditional to timber transportations are dependent on this river. Now the river is a severe suffering pollutant spill from many sources. Anthropological activities were higher contributions in the degradation of river environments. Many works were reported about pollution in Siak river. But how the distribution of model sediment transport in the mouth of the river is less to be explained. We consider hydrodynamics model of the mouth of Siak river for modeling the sediment distribution. This simulation gives a fundamental and clear understanding of how total solid sediment (TSS) distribution when flood and ebb tide happens. At ebb tide, TSS dispersion is higher than at flood tide. There is found that the sediment is concentrated in the plume of Siak river in Bengkalis strait. The composition of the sediment is dominated by organic matters.

Abstract

Studying Singapore Strait waters condition as a form of maritime mitigation is necessary because it is an international shipping lane. The dominant weather changes include rainfall, wind flows, and sea surface temperature (SST). This study aims to reveal the relationship between rainfall and SST activity in the Singapore Strait for over 18 years, from 2002 to 2019. The results showed a negative correlation, where the SST decreases as rainfall increases and vice versa. In addition, the high rainfall and low SST distribution occur in the Western season (December–February). The low rainfall intensity and high (warm) SST distribution occur yearly in the transition from West to East (March–August). Also, the distribution pattern is influenced by rainfall intensity and the water mass from the South China Sea and the Malacca Strait, where the strait is a mixture of these masses. The neural network model confirmed the negative correlation. Hence a small change in SST causes rainfall if it is cooler, and less precipitation if warmer.
