Abstract

Hutan mangrove merupakan salah satu hutan di daerah tropis yang berperan besar dalam hal penyerapan dan penyimpanan karbon. Kerusakan hutan mangrove yang terjadi bersumber dari perilaku masyarakat untuk membuka lahan tambak, budidaya perikanan, dan penebangan liar untuk produksi kayu maupun pembangunan pemukiman baru, sepertihalnya yang terjadi pada hutan mangrove di Teluk Lamong yang merupakan lokasi studi pada penelitian ini. Lokasi tersebut telah mengalami pembabatan akibat adanya pembangungan pada wilayah Romokalisari. Pada penelitian ini dilakukan penghitungan pendugaan biomassa dengan menggunakancitra satelit Pleiades 1-A tahun 2015, serta nilai dari allometrik biomassa dari data pengukuran di lapangan. Metode pengambilan sampel yang digunakan yaitu plot acak dan tanpa pemanenan. Algoritma indeks vegetasi yang digunakan yaitu Normalized Difference Vegetation Index (NDVI). Allometrik biomassa yang digunakan untuk menghitung keseluruhan mangrove dalam penelitian ini adalah BAP = 1,2218.D1,679. Berdasarkan hasil penelitian, nilai koefisien korelasi NDVI Citra dengan biomassa di lapangan sebesar 0,728. Nilai koefisien korelasi NDVI Citra dengan NDVI Foto sebesar 0,341. Nilai koefisien korelasi biomassa di lapangan dengan salinitas sebesar 0,797. Nilai koefisien korelasi biomassa di lapangan dengan pH sebesar 0,264. Pada persebaran biomassa hutan mangrove Teluk Lamong pada tahun 2018 terbagi kedalam tiga kelas, yaitu pada kelas rendah, biomassa mencapai 0 – 50 ton/ha, pada kelas sedang mencapai 50 – 400 ton/ha, dan pada kelas tinggi mencapai 400 – 700 ton/ha. Total keseluruhan biomassa hutan mangrove di Teluk Lamong pada tahun 2018 sebesar 6.593,850 ton/ha.================ The mangrove forest is one of the forests in the tropical which has role as a major of carbon absorption and storage. The damage of mangrove forests occur due to the behavior of the community to build fishpond, aquaculture, and illegal logging for timber production or construction of new settlements, as it happens at the mangrove forest on the Lamong bay which is the study location in this research. This location has been deforested due to construction at Romokalisari. This research calculated biomass prediction using satellite images of the Pleiades 1-A 2015 and the value of allometrik biomass data from measurements in the field. Method of sampling in the field used is random plot and non destructive sampling. The algorithm used is Normalized Difference Vegetation Index (NDVI). Allometrik biomass used to calculate overall mangroves in this research is BAP = 1,2218.D1,679. Based on the results of the research, the correlation coefficient value of NDVI satellite imagery with biomass in the field is 0.728. The correlation coefficient value of NDVI satellite imagery with value of NDVI photo is 0.341. The value of the correlation coefficient of biomass in the field with the salinity is 0.797. The value of the correlation coefficient of biomass in the field with pH is 0.264. Biomass distribution of mangrove forests on the Lamong bay in 2018 is divided into three classes, which are, on low grade biomass reached 0 – 50 ton/ha, on the middle class reached 50 – 400 ton/ha, and on high class reached 400 – 700 ton/ha. The total biomass of mangrove forests in the Lamong Bay in 2018 amounts to 6,593.850 tons/ha.
