Abstract

Many species of sea urchins (Echinoidea) can be found in the waters of Sembalagi Beach, Siompu Island. However, the diversity of sea urchins (Echinoidea) on the coast has not been scientifically researched and published. This study aims to determine the types, hunting, poaching and dominance of sea urchins (Echinoidea) at Sambalagi Beach, Siompu Island, South Buton Regency. This study uses a quantitative descriptive method with observation techniques. There are three research stations, namely station I (rocky and seagrass substrate), station II (sandy and seagrass substrate), and station III (rocky and seagrass substrate). The data obtained were analyzed using the formulation of documents, documents, secrecy and Shannon-Winner domination. The results showed that there were 5 species of sea urchins (Echinoidea) which namely Diadema setosum, Echinothrix calamaris, Tripneustes gratilla, Echinometra mathaei and Salmacis sphaeroides. The species diversity index (H') for the three abnormalities was classified as moderate, namely station I (H' 1,34), station II (H' 1,18) and station III (H' 1,22). The highest relative abundance of Echinoidea was found in Tripneustes gratilla species at Station II (37,67%) which had a lot and the lowest relative decline index was found in Echinothrix calamaris and Echinometra mathaei at Station III (1,52%) less abundant. The highest evenness index is at station II (0,85) which is very even and the lowest is at station III (0,76) which is more evenly distributed. And the highest dominance index is at station II (0,32) with moderate dominance and the lowest dominance index is at station I (0,29) with low dominance.

Abstract

Insect diversity is believed to serve as one of the bioindicators for the condition of an ecosystem.In this investigation, data pertaining to the density of mangroves were collected by extracting samples from designated stations. This was achieved by utilizing the transect line and quadrat approach, known as the Transect Line Plot method. The data were gathered through observation plots measuring 10x10 m2, aiming to document the mangrove vegetation categorized as trees.At each station, any insect samples identified were subjected to characterization based on their morphological traits, utilizing an insect identification guide.Based on the research results, there are six mangrove species among themfindings obtained through field research at four observation station sites unveiled the existence of six distinct variations of mangrove forest types within the coastal region of Wundulako District. Among these, four types belonged to the Rhizophoraceae family, specifically Rhizophora apiculata, Rhizophora Mucronata, Ceriopstagal, and Bruguiera Gymnorrhiza, . Additionally, there was one species from the Combretaceae family, Lumnitzeraand Racemosa, and another from the Sonneratiaceae family, Sonneratia Alba. Generally, the density of the mangrove ecosystem was determined to be ranging from moderate to dense.Furthermore, a scrutiny of the insect diversity index yielded values of 1.23 for Station I, 1.39 for Station II, 1.36 for station III, and 1.69 for sStation IV. Based on the findings derived from the research, it is plausible to conclude that the condition of the mangrove ecosystem in Wundulako District across the four stations varies from limited to extensive. Additionally, the outcomes from the insect diversity index suggest a relatively reduced level of insect diversity.
