      Abstract
      Mangrove mudah tercemar karena tumpahan minyak di perairan laut yang dapat menyebabkan kematian. Penelitian mengenai dampak cemaran minyak terhadap kerusakan anatomi batang mangrove belum banyak dilakukan, khususnya pada mangrove di pantai sekitar Jakarta. Penelitian ini bertujuan menduga keberadaan minyak pada pembuluh xilem batang mangrove pada lokasi yang tercemar minyak dan menghitung jumlah pembuluh xilem yang terisi minyak untuk menduga fungsi fisiologinya. Metode untuk menganalisis jaringan secara anatomi menggunakan perangkat lunak Adobe Photoshop dan ImageJ untuk menghitung jumlah, luas, dan persentase pembuluh xilem batang yang terisi minyak. Hasil penelitian menunjukkan terdapat perbedaan nyata pada nilai densitas pembuluh xilem antara perlakuan terpapar minyak dan kontrol. Tiga spesies mangrove yang diamati menunjukkan bahwa Rhizophora mucronata memiliki persentase pembuluh xilem yang diduga terisi minyak paling rendah dibandingkan dengan Avicennia marina dan Avicennia alba.
       
      Mangroves are easily polluted due to oil spills in marine waters which can cause death. Research on the impact of oil contamination on the anatomical damage of mangrove trunks has not been widely carried out, especially on mangroves on the coast around Jakarta. This study aimed to estimate the presence of oil in the xylem vessels of mangrove stems in oil-contaminated locations and count the number of oil-filled xylem vessels to estimate their physiological function. Methods to analyze tissue anatomically using Adobe Photoshop and ImageJ software to calculate the number, area, and percentage of oil-filled stem xylem vessels. The results showed that there was a significant difference in the value of xylem vessel density between the oil-exposed treatment and the control. The three mangrove species observed showed that Rhizophora mucronata had the lowest percentage of xylem vessels thought to be filled with oil compared to Avicennia marina and Avicennia alba.
