Abstract: | Sebanyak 50% hutan mangrove telah mengalami penurunan luas selama 2-3 dekade terakhir. Salah satu faktor yang berperan pada kematian mangrove adalah cemaran minyak di pantai habitat mangrove. Minyak di perairan pantai akan memengaruhi sistem perakaran, sehingga pertumbuhan mangrove terganggu yang dapat berakibat kematian. Keberadaan minyak dalam jaringan akar, batang maupun daun pada mangrove akan memengaruhi pergerakan air melalui pembuluh xilem. Oleh karena itu, penelitian ini bertujuan menganalisis keberadaan minyak dalam pembuluh xilem daun mangrove yang tercemar minyak. Penelitian ini menggunakan 3 spesies mangrove yaitu Avicienna alba, Avicienna marina dan Rhizopora mucronata. Metode yang digunakan dalam penelitian ini adalah dengan preparat anatomi daun mangrove. Analisis sampel menggunakan perangkat lunak Adobe® Photoshop dan dilanjutkan dengan aplikasi ImageJ untuk mendapatkan nilai-nilai numerik dari foto sampel. Hasil penelitian menunjukkan bahwa pembuluh xilem daun Rhizopora mucronata lebih banyak terisi minyak dibandingkan dengan pada genus Avicienna. As much as 50% of mangrove forests have experienced a decline in an area over the last 2-3 decades. One of the factors that play a role in the death of mangroves is oil contamination on the coast of mangrove habitats. Oil in coastal waters will affect the root system, so that mangrove growth is disturbed which can result in death. The presence of oil in the roots, stems and leaves of mangroves will affect the movement of water through the xylem vessels. Therefore, this study aimed to analyze the presence of oil in the oil-contaminated xylem vessels of mangrove leaves. This study used 3 mangrove species, namely Avicienna alba, Avicienna marina and Rhizopora mucronata. The method used in this research is the anatomy of mangrove leaves. Sample analysis using Adobe® Photoshop software and continued with ImageJ application to obtain numerical values from sample photos. The results showed that the xylem vessels of the Rhizopora mucronata leaves were filled with oil more than those of the genus Avicienna. |
