Analysis of marine garbage catches in mangrove roots of rhizophora sp in senggarang besar, tanjungpinang, Indonesia

Abstract

Rhizophora sp has a single root. The shape of the roots, which are like anchors, is what makes mangroves wave absorbers, sediment binder, and so on. One of the functions of mangrove roots is to prevent the release of garbage into the open sea. This is due to the shape of the roots that make garbage snagged (caught) on the sidelines of the roots. The purpose of this study was to analyze the capture of marine debris in the mangrove roots of Rhizophora sp in the Sengarang Besar ecosystem. This research was conducted in December 2021 in the mangrove forest of Senggarang Besar. The method used is the line transect method with 10 Rhizophora sp mangrove trees located on the coast. Then, data analysis on the density of waste caught in the mangrove roots of Rhizophora sp. The results showed that the inorganic waste found in the mangrove roots of Rhizophora sp were plastic waste, metal waste, glass waste, rubber waste, and cloth waste. Plastic waste is the highest waste catch in the mangrove ecosystem of the Great Senggarang beach. Then the data that has been taken is analyzed using Pearson correlation to prove whether there is a relationship between the circumference and the type of garbage caught. The results of the Pearson correlation between cloth and plastic with root circumference were -0.30 and -0.04 (no correlation between the two variables); Pearson glass correlation with root circumference was 0.45 (sufficient correlation); Pearson rubber correlation with circumference is 0.71 (strong correlation). It can be concluded that there are other factors such as geographical influences, ocean currents, and others in the catch of garbage at mangrove roots.
