Abstract

This research evaluates the performance of coastal safety structures in mitigating wave runoff through laboratory-scale simulations. Pancana Beach in Barru Regency, South Sulawesi, was selected as the research site due to its vulnerability to wave-induced beach damage. To simulate wave conditions, a wave generator was designed using a 12-volt DC motor integrated into an acrylic wave bath. This research analyses the effectiveness of three types of coastal safety structures: reflectors, sea walls and sloping sea walls. Laboratory experiments measured the wave overflow volume for each type of structure under controlled conditions. The results showed that reflector-type structures achieved the highest efficiency in mitigating wave overtopping, with an average minimum overtopping value of 0.006 m³/ms. The findings emphasise the importance of selecting and designing appropriate coastal protection measures to minimise coastal erosion, protect coastal infrastructure and reduce risks to surrounding settlements. This study contributes valuable insights into the role of engineered structures in enhancing coastal resilience, especially for areas vulnerable to high wave energy.

Abstract

This study aims to determine the factors that affect the catch of mackerel in the potential zone of fishing grounds in the Makassar Strait, namely; oceanography sea surface temperature, salinity, current velocity, depth and sea surface chlorophyll content on the catch of mackerel in the potential zone of fishing grounds in the Makassar Strait. The research method used is the survey method, which directly follows the fishing operation. The number of observations was 38 times. Data were analyzed with histogram graphs and also analyzed with multiple linear regression. The results of this study showed that mackerel were generally caught in waters with temperatures between280Cand290C; salinities of 30 ppt and 31 ppt; water depths of about 50 m and 60 m; current speeds of about 0.09 m/s and 0.12 m/s; and chlorophyll-a content of about 1.80 mg/m3 and 2.20 mg/m3. This study has explained that chlorophyll-a content is the dominant factor in relation to mackerel catch.

Abstract

Indonesian waters have potential ornamental coral resources in South Sulawesi waters, especially in Karanrang Island, which still need to be optimally utilized by the fishing community. The main objective of this community service is to increase the understanding and skills of the community in managing coral transplantation in situ and caring for them in an environmentally friendly modular system aquarium based on re-circulation. Adopting the ABCD (Asset-Based Community Development) method, this approach begins with the identification of local assets, including the expertise and skills of the karanrang island community. Subsequently, capacity building is carried out by utilizing these assets, and the community is actively involved in the planning and implementation process. Results included increased community knowledge on technological innovations of modular circulation systems holding aquarium design at the household scale and post-harvesting of coral transplant farming products for holding in aquariums. This process contributed to the development of the local ornamental coral sector, empowered the community, and opened up product marketing opportunities at both local and international levels.
