Information on macroalgae species and their distribution in the coastal areas of Kolaka Regency is extremely limited. This research is a preliminary study of macroalgae species found along the coast of Kolaka Regency, conducted in the waters of Tanggetada Village. The research applied the belt transect method and 1 x 1 m quadrats using a 50 m long line transect with a placement interval of each quadrat of 5 m, which was repeated 3 times with a distance of 50 m between line transects. The results showed that 20 species of macroalgae, namely Caulerpa verticillata, Caulerpa racemosa, Dyctiosphaeria versluysii, Dyctiosphaeria cavernosa, Udotea sp., Halimeda opuntia, Halimeda macroloba, Halimeda sp., Boodlea composita, Gelidiella acerosa, Hormophysa triquetra, Sargassum sp., Lobophora variegata, Padina minor, Liagora sp., Avrainvillea obscura, Gracillaria coronopifolia, Valonia aegagropila, Acanthophora spicifera, and Dictyota dichotoma, come from 3 group, namely 11 species from the Chlorophyta, 5 species from the Rhodophyta, and 4 species from the Phaeophyta. Water conditions in Tanggetada village still support macroalgae growth. Further research with a wider scale is needed in the observation area to reach the coral reef area and an overview of the ecological index of macroalgae in the Tanggetada village.

This study aims to report the diversity of the Halimeda genus on the West Aceh coast. Data was collected in the Lhok Bubon Coastal intertidal area, Samatiga, West Aceh Aceh Province. Macroalgae samples were collected using the cruising method along the beach with a depth of 1-2 m at low tide. The Halimeda genus found four species, namely Halimeda macroloba, Halimeda macrophysa, Halimeda incrassata, and Halimeda simulans. Halimeda macroloba was found to have a whitish-green talus. Halimeda macrophysa samples have irregular talus branches. Description Halimeda incrassata at the study site is light green, and the holdfast is attached to the sandy substrate to form large sediment clumps. Halimeda simulans were found to be linked to sand, which tends to have a finer texture. The results of this report provide information that Lhok Bubon Beach, West Aceh, has macroalgae potential that needs further study.

Seagrass beds are highly productive ecosystems and have ecosystem services in the coastal zone but are continuously declining globally. Mainly due to anthropogenic activities that reduce the amount of light entering the waters and reaching seagrasses, such as dredging, reclamation, sedimentation, and eutrophication. This research was conducted to determine the relationship between turbidity level and seagrass composition and morphology. The observations were conducted in November 2016 in Pangkep district on Sagara Island and Makassar City on Barrang Lompo and Lae-lae Island, South Sulawesi Province. The observation stations are determined based on the level of turbidity conditions. Sagara Island, Barrang Lompo, and Lae-lae are areas that are considered to represent turbid waters, by laying a line transect (roll meter) perpendicular to the coast and doing it 3 times. The data collected in this study related to seagrass conditions such as seagrass composition and seagrass morphometrics. Variables observed in seagrass leaf morphometric observations were leaf surface area and leaf width, leaf thickness, and distance between internodes. In addition, other data collected is environmental parameter data, such as currents, TSS, PAR, temperature, and salinity. One-way ANOVA analysis showed that there was a difference in turbidity levels between Barrang Lompo Island, Sagara Island, and Lae-lae Island with a significance value of 0.000. The types of seagrasses found on Barrang Lompo with light availability of 1735.23 mol/m/s are Enhalus acoroides, Cymodocea rotundata, Halodule uninervis, Halophila ovalis, Thalassia hemprichii. On P. Sagara with light availability of 170.01 mol/m/s, E. acoroides, T. hemprichii, Cymodocea serrulata, H. uninervis, and H. ovalis were found. Whereas in P. Lae-lae only E. acoroides was found. The results showed that the level of turbidity has an influence on seagrass morphometrics, namely leaf ratio and leaf thickness of E. acoroides species, and internode distance in H. uninervis species.Keywords:Availability of lightMorphometricsPARSeagrass bedsTurbidity

Tanggetada Village has very large potential for marine fishery resources. However, this potential has not been optimally utilized. One of the problems is that the majority of fishermen in the village are small fishermen who have traditional fishing gear with low catch production. Therefore, to increase catch production, this community service activity provides training and assistance to fishermen groups to create fishing gear technology that can increase catch production and is environmentally friendly. The fishing gear used is the Bubu (Fish trap). The partner of the fishermen group in this activity is the Kelompon Nelayan Anak Pesisir of Tanggetada Village. This activity was carried out in August 2024. The activity method was carried out in several stages including the Socialization stage, training and assistance in making Bubu (Fish trap), application of bubu and evaluation of activities. The results of this activity were an increase in the knowledge and skills of fishermen group partners regarding the method of making Bubu, and being able to apply the fishing gear technology.
