Absorpsi Dispersant Linear Alkylbenzene Sulfonate (LAS) Oleh Fitoremediator Tanaman Rhizophora mucronata

---

Linear alkylbenzene sulfonate (LAS) is included in the group of anionic surfactants. LAS only decomposes by 50% and takes 9 days. LAS is a detergent originating from industrial and petroleum waste. LAS compounds can deteriorate the quality of seawater by reducing the dissolved oxygen in water quality. One method that can be used to control LAS pollutants is by using phytoremediation methods. Phytoremediation involves the use of plants and related microorganisms to degrade, transform, or absorb pollutants. One plant that can be used is the Rhizophora mucronata plant. This study is an experimental study utilizing phytoremediation from R. mucronata plants to control LAS pollutants in seawater media. After preparation and acclimatization stages with the plants, the implementation phase involves preliminary testing to determine the level of LAS concentration used. The concentration levels used are different, namely M0 (Control without plants), M1 (25 ppm), M2 (100 ppm), M3 (175 ppm), M4 (250 ppm), and M5 (325 ppm). The method used is a Completely Randomized Design (CRD) with one factor of five treatments with 3 repetitions. The absorption rate of LAS by R. mucronata plants M1(25) - M5(325) > 95% and M0 (Control without plants) >75%. LAS concentration absorption significantly affects dissolved oxygen analyzed in the 2nd and 4th weeks. From the 2nd to the 4th week, dissolved oxygen increased from 17.79% to 24.97%. The analysis results using a simple linear regression equation to observe the simultaneous effect of LAS residues on DO have an influence of 99.9%, indicating a very strong correlation.
