Abstract

The current marine environment has begun to be polluted and will directly affect the biota around it. The study of health conditions and spatial variations in the characteristics of the population of Rhizophora apiculata was carried out in the mangrove ecosystem around the oil and non-industrial areas of Riau Province. This study aims at a baseline for evaluating mangrove management in Riau Province. Sampling is carried out using line transects drawn from the reference point (outermost mangrove stands) in a direction perpendicular to the coastline to the mainland and sample plots made with a size of 10 X 10 m2. Samples of leaves, fruits, and flowers are taken randomly based on the sample plots made. Then preserved with 70% alcohol and labeled. The preserved samples were taken to the laboratory to measure morphometrics and calculate the number of stomats. The results showed that the population of R. apiculata at all stations was in an unhealthy condition. In addition, individual competition and adaptability possessed by the population of R. apiculata are very low, ranging from 09.53 - 17.27% and illustrating more group growth and very high competition among individuals. Furthermore, the discriminant analysis shows that the morphometric variables that most characterize the population of R. apiculata in the oil industry with non-industrial areas are the length of the stem. Based on the results of PCA analysis, the variables that most determine the poor health of the population of R. apiculata are the parameters of Pb heavy metals, pH, temperature and DO waters.

Abstract

Kajian faktor penentu kesehatan populasi Rhizophora apiculata telah dilakukan pada ekosistem mangrove sekitar kawasan industri perminyakan dan non kawasan industri di Provinsi Riau yang berdasarkan karakteristik lingkungannya dengan menggunakan Analisis PCA. Penelitian ini dilaksanakan pada bulan November hingga Desember 2014 di pesisir pantai Kota Dumai dan Kabupaten Bengkalis dengan tujuan sebagai dasar evaluasi terhadap pengelolaan mangrove di Provinsi Riau kedepannya. Pengukuran kualitas perairan dilakukan dengan cara insitu dan sampel sedimen diambil menggunakan eckman grab pada daerah intertidal dengan kedalaman air 5 – 10 m. Hasil penelitian menunjukan bahwa kondisi kesehatan populasi R. apiculata dipengaruhi oleh tiga faktor. Faktor pertama adalah parameter logam berat Pb, pH, suhu dan DO. Faktor kedua adalah parameter TPH dan trigliserida. Sementara faktor ketiga adalah salinitas dan potensial redoks. Kemudian masing-masing faktor memiliki nilai varian yang berbeda-beda yakni 33.36% (faktor pertama), 30.34% (faktor kedua) dan 15.57% (faktor ketiga). Dari ketiga faktor tersebut, yang paling mempengaruhi kondisi kesehatan populasi R. apiculata pada kawasan industri perminyakan dan non kawasan industri di Provinsi Riau adalah parameter logam berat Pb, pH, suhu dan DO.
