Empowerment and Optimalisation of Kenjeran Beach Tourism Potential, Surabaya-East Java

Coastal management is interested in restoring the natural conditions of increasing the comfort of the community after being degraded due to reclamation, as in Lamong Bay. Therefore, it is necessary to know the character of the current pattern vertically in the study area. This paper aims to find out the current vertical pattern by referring to the shape of the Ekman Spiral. This concept is based on the implementation of surveys and the presentation of currents with hydrodynamic analysis in Lamong Bay. The survey has been carried out at five points, presented with measurement results, and analyzed to the character of the current spiral pattern to depth. Tidal measurement and modeling are also carried out to determine the validation of current measurements synchronized with their position and time. The results obtained in the form of a spiral are not exactly according to the shape of the Ekman Spiral theory, namely on the Southern Hemisphere Earth rotating towards the left. The speed is getting lower and smaller i.e. getting smaller and smaller to the depths (average of CM-1: 0.24 m/s for 0.2D, 0.21 m/s for 0.6D, and 0.18 m/s for 0.8D). Validation of tidal and current measurements from measurements and models qualitatively obtained minimal errors.

“…Indonesia is an archipelagic country with a long coastline. As an area bordering the ocean, the coast also has the potential to experience damage, such as erosion, sedimentation, and damage to coastal areas which can cause changes in the existing coastline [1]- [7] and disrupt beach tourism [8] [9]. These coastal problems can be overcome by natural protection with mangroves or bamboo [10]- [12] or by building protective structures to protect the coastline from existing problems.…”

Effect of Interparticle Distance on Smoothed Particle Hydrodynamics on Wave Transformation Through Submerged Breakwater

Sujantoko,

et al. 2024

Beach abrasion and erosion are problems that many beaches in Indonesia experience. Waves are the most influential processes in this phenomenon. When the waves move towards the coast, they will transform, generating currents near the coast. Currents moving along the coast displace sediment on the beach, causing changes in the shoreline. So it is necessary to carry out coastal protection efforts so that abrasion does not occur, which results in the erosion of coastal areas so that the island’s area is reduced and the coastline retreats. To overcome this problem, one of the supporting facilities is a submerged breakwater. In this paper, researchers will numerically study the effect of particle size on smoothed particle hydrodynamics (SPH) when waves pass through a submerged breakwater structure. The simulation is carried out on a Numerical Wave Tank (NWT), the piston is at the end of the tank, and the structure of the submerged breakwater is set according to the experimental scenario. The distance between the particles varied from 0.03, 0.025, 0.02, 0.015, and 0.01. The results show that the smaller the distance between the particles used, the wave elevation results are closer to the experimental model.

“…When talking about tourism services, it cannot be separated from beach and sea tourism. Even beach and sea tourism development is environmentally sound [1][2][3][4].…”

Increasing Globalization Business and Ecotourism Branding on the Beach of Delegan, Gresik, East Java

Mustain,

2024

Developing and managing ecotourism is an effort to utilize local resources optimally. Delegan Beach in Gresik, East Java, is an area for the management and development of ecotourism. This study aims to determine the potential resources in the Delegan beach tourism object using the Analysis Hierarchy Process (AHP) method. Based on the analysis, Delegan Beach has potential ecotourism because of the sloping beach topography, calm waves, and white sand. However, the development of Dalegan Beach as ecotourism has several obstacles, including the lack of supporting infrastructure for tourist attractions, cooperation between village communities and local governments, and poor management so that ecotourism development has not been maximized. The main priority of the policy regarding management studies and the potential of the Gresik coastal area, according to stakeholder perceptions, is the empowerment of human resources 51%, then followed by the development of tourism branding by 26% as the second priority, followed by the development of tourist destinations by 16%, and the last is ecotourism-based management. by 8%. The study’s results also show that the determinants of the development of the Delegan Beach tourism area influence the forms of participation carried out by the local community. The resulting development directions include utilizing various resources, developing facilities as community business opportunities, empowering community skills, increasing area promotion, and efforts to preserve the environment.
