Abstract

Abstract During Covid-19 outbreak, the production of the Vannamei Shrimp (Litopenaeus vannamei) actually increased and even increased the value of Indonesia's exports. The existence of shrimp culture is closely related to the nature of the surrounding environment, especially climate change. Climate change has a potential impact on aquaculture production, which affects livelihoods that depend on aquaculture. This study aims to analyze the development of sea surface temperature (SST) and high tides over the last 10 years and to analyze the vulnerability of the vannamei shrimp culture to climate change. This research uses a descriptive method. Data were collected through direct interviews with respondents, while the model was a structured interview. Secondary data were obtained from satellite imagery through geographic information systems, and from literature. Data analysis used spatial analysis with Geographic Information Systems (GIS), and vulnerability analysis was carried out to build the Livelihood Vulnerability Index matrix. The results show that climate change affects the development of sea surface temperature (SST) and high tides on the coast of Banyuwangi Regency, East Java Province, Indonesia. It is proven that during the last 10 years SST and high tide data shows that it fluctuates every year, SST between 27.75-29.6°C, the high tide between 1.47-1.57 m. Changes in SST affects high tide, and both become variability that affects vannamei shrimp culture. The results of the vulnerability analysis show that vannamei shrimp culture livelihoods in Banyuwangi Regency are categorized as vulnerable to climate change, with a value of 3.30 (3.34 vulnerability threshold).

Abstract

Graphical Abstract Highlight Research  1. Assessment of aquifer potential around vannamei shrimp ponds on the coast of Banyuwangi Regency. 2. Lithology along the coast of Banyuwangi Regency. 3. Estimation of groundwater potential around vannamei shrimp ponds on the coast of Banyuwangi Regency. 4. Aquifer depth, which is related to seawater intrusion based on aquifer layer color.   Abstract The coast of Banyuwangi Regency is an area with high human activity involving the use of groundwater in aquifers, including activities related to vannamei shrimp farming. Therefore, seawater intrusion is suspected to occur, given that this area is adjacent to the sea. To assess the potential (distribution and depth) of the aquifer and the suspected seawater intrusion around the vannamei shrimp farming area. This approach is new because the aquifer assessment is conducted around the vannamei shrimp farming area as a basis for sustainability, especially in relation to the estimated seawater intrusion around the area. Data was collected through surveys and direct observation, by dividing the measurement area vertically and horizontally. Detection was carried out using AIDU Golden Rod (AGR), including data analysis using AIDU Prospecting software. The results of the study indicate that the productivity of aquifers around vannamei shrimp ponds in Banyuwangi Regency, for water discharge between < 5 L/second - > 10 L/second, and aquifer depths ranging from 5 to 155 m, shows indications of seawater intrusion around vannamei shrimp farms. The aquifer zone includes moderate to high productivity stretching along the geological structure, where seawater intrusion has occurred around the shrimp ponds indicated in blue. Therefore, further research is needed on the analysis of seawater intrusion values as a basis for sustainable groundwater management policies.
