Abstract

Senggarang is one of the coastal villages in Tanjungpinang City which has a river that flows from the upstream downstream into the sea. The flow of the Senggarang river has distinctive characteristics that are commonly found in small island waters, namely having a relatively short upstream to downstream distance, and the downstream part is influenced by tidal conditions. Various activities along the Senggarang river flow would cause changes in water quality which would impact the presence of macrozoobenthic. The objective of this study was to determine the relationship between the macrozoobenthic community and the water quality of the Senggarang river. Macrozoobenthic sampling, and environmental parameters were carried out using random sampling methods. The results of this study were obtained 27 species from 6 phylum, namely phylum Arthropoda 13 species, phylum Ciliophora 3 species, phylum Echinodermata 1 species, phylum Mollusca 4 species, phylum Nematoda 5 species, and phylum Tardigrada 1 species. The average macrozoobenthic density is 172 ind./ m3 for freshwater and 704 ind./ m3 for brackish waters. The average diversity value for freshwater is 1.29 and 2.16 waters with medium salinity, the average uniformity value of 0.85 freshwater and 0.94 of high in brackish waters, the average dominance value of 0.32 freshwater and 0.13 of low in brackish waters. The relationship of macrozoobenthos with the quality of freshwater based on PCA analyses related to temperature and dissolved oxygen, in brackish waters to temperature, dissolved oxygen, and current.Keywords: Macrozoobenthic community, PCA, River flow, Water quality

Abstract

Sea cucumbers which have the scientific name Holothuroidea are fishery commodities that have high economic value and are in great demand in the global market. Sea cucumbers are the main commodity of Benan Village which is the outermost island of Lingga district. Most of the people in Benan Village work as sea cucumber fishermen. As an aquatic resource owned by the village, sea cucumbers are still constrained in terms of handling so that it reduces the selling value of the dried sea cucumbers produced. Therefore, it is important to empower the people of Benan Village regarding the postharvest handling of sea cucumbers which aims to improve the quality as well as directly increase the selling value of that resources. Community empowerment activities are expected to add insight and improve the ability of the Benan Village community in handling sea cucumbers post-harvest. Empowerment was carried out through three methods, namely the distribution of questionnaires and discussions in the form of questions and answers with the Benan Village community group regarding the problem process in handling post-harvest sea cucumbers, which was carried out after distributing questionnaires to the sea cucumber aquaculture community, then education and discussion on good procedures were carried out in post-harvest handling. To improve the quality of this sea cucumber commodity, then in the third stage, mentoring and practice regarding the correct handling of sea cucumbers is carried out to produce good quality sea cucumbers from washing to packaging. The selection of discussion methods, lectures/education, and direct practice is considered effective in increasing public knowledge about the process of handling sea cucumbers postharvest properly and correctly, considering that the target stakeholders are sea cucumber farmers.
