The Benefit of Wind Distribution Analysis for Coastal Construction Design in East Java Province

To create a safe and durable coastal structures design, a comprehensive data including minimum, maximum, and significant sea wave’s height are needed. Normally, to obtain such massive data, engineers need to elaborate specialized consultant to carry out direct measurement on site, which typically consumes enormous financial resources and involves exceptionally rare experts. In such case, engineers can use a set of 10 to 20 years wind data as a substitution. The suggested duration is expected to ensure that the set of data has sufficient information, which includes extreme wind speed and its fluctuation along the respective years. Therefore, it is common to adopt available data at the nearest wind stations, such as airports and harbors, to estimate the wind features on site. This paper presents a normative wind speed distribution model based on 16 years’ wind data at a location obtained from National Oceanic and Atmospheric U.S. Department of Commerce (NOAA). The outcomes of the research show that the maximum sea wave height prediction in Sidoarjo Regency East Java with respect to analytical and graphical method are 0,465 m and 0,840 m, respectively. The results are considered satisfactorily reliable to be used as primary data to design coastal structures

The Benefit of Hydrodynamic Model As an Assessment of the Hydro-Environment Engineering in Decision Support System for the Sustainable Mariculture Development in Indonesia

Indonesia has a great potential for developing the mariculture industry. However, during the operation faced a lot of problems due to hydrodynamic environment engineering fields. The main case was the misplaced location of the mariculture development with respect to the weak sea current in the vicinity area. Meanwhile, the accomplishment of sustainable practices and management systems to preserve coastal environments is still in its infancy. Therefore, it is vital to improve aquaculture technology and to develop management tools. This problem can be determined by an implementation of the numeric mathematical model of the sea current flow which illustrates the physical process of domain area. At this manuscript, the assessment utilized 2-dimensional numerical models in Decision Support System (DSS) at the Ekas Bay, Lombok Indonesia. Simulations were carried out by applying the open source of Delft3D modeling system which was fully integrated with modeling framework for the simulation, among others of flow and waves. The outcomes prove that hydrodynamic model can be used as an initial assessment for decision maker for future development of sustainable mariculture industry in Indonesia

THE SYNOPTIC DATA FOR ADAPTATION CLIMATE CHANGE IN SIDOARJO REGENCY EAST JAVA

As the biggest archipelago country in the world, many places in Indonesia are potential for maritime economy industries but also suffered from negative impact of the global sea level rise. It was identified as one most contributing factors which is threatening Indonesia coastal water by coastal flood, including the research area where is in Sidoarjo Regency. To adopt the climate change, it is compulsory to have knowledge and technology along with data, unfortunately insufficient raw data in research area have identified as a major problem during years. The purpose of this research is to utilize synoptic data for coastal adaptation of climate changing design and construction. The data were collected from the National Oceanic and Atmospheric Administration (NOAA) for 16 years that will be processed into wind rose and fetch length. The outcomes are going to be obtained from the analysis of graphical and analytical calculations. The results prove that the using of synoptic data analysis give an accurate forecasting of maximum sea wave height at the research area in the range of 0.30 – 0.88 m, then it can be used to determine appropriate adaptation to the sea level rise due to global climate changing

THE UTILIZATION OF THE DRONE AND SONAR FOR FLOOD DESIGN IN CONSTRUCTION ERA 4.0.

Climate change caused by global warming has become an interesting study in recent years which is indicated by an increase in seawater temperature, sea-level rise and flooding. In the research area at Jabon District Sidoarjo was affected by sea flood in December 2017 within material loss about 5 billion rupiahs. This research aims to utilise the recent technology in construction era 4.0 with photogrammetric techniques using Unmanned Aerial Vehicles and sonar tools to analyse flooding events by making bathymetry maps with low and affordable costs in watersheds, including the effects of tides was also carried out. The method in this research was carried out the right photogrammetric technique and processed to provide a 3-dimensional appearance. Also, sonar tools use as benchmarks with high accuracy in the bathymetry mapping and river sedimentation occurrence. The outcome of this study proves that the watershed at the study site was a tidal influence on the condition of the highest high water level, which caused seawater to pass through the river bank as high as 10 centimetres. Fur further to overcome this problem, it recommends to do dredging of the riverbed, and the appropriate construction of river banks/embankments are higher and more durable

The utilisation of the numerical hydrodynamic model to face rob floods in coastal areas in the industrial revolution era 4.0 at east java Indonesia

Global warming which occurred has resulted in sea level rise resulting in Rob flooding in coastal areas. The research location is in Rob floods area in Tegalsari Hamlet, Jabon Subdistrict, Sidoarjo that have damaged seaweed cultivation, and estimated losses reached 5 billion rupiahs in early 2018. Therefore, it needs to do research numerical hydrodynamic models to prevent this flood. However, the devices for measurement data are too expensive. The purpose of this research is to utilise economical devices measurement based on the industrial revolution 4.0 with numerical hydrodynamic methods models in the field of civil engineering. This model is an approach to estimate the hydrodynamics of coastal waters such as tides, currents and water levels. To simulate the hydrodynamic model, for nearshore bathymetry data are gained from sonar and offshore bathymetry data from GEBCO. The simulations utilise open-source Delft3D software using the Navier-Stock formula. The outcomes prove that hydrodynamic simulation models can be used to estimate sea-level rise for the next few years in coastal areas. Thus, the determination of the type of construction of civil engineering buildings that are strong and environmentally friendly so that publics do not cause huge losses and make coastal communities resilient to disasters
