"ABSTRAK Ekosistem perairan dan daratan di sepanjang jalur pantai utara Pulau Jawa membentuk ekosistem mangrove menjadi ekosistem yang kaya akan keanekaragaman hayati yang saling berinteraksi, salah satunya di Desa Pantai Bahagia yang berada di Kecamatan Muara Gembong Kabupaten Bekasi, Jawa Barat. Pada kenyataannya, dari tahun 1999 hingga 2014, hutan mangrove di desa ini terus mengalami degradasi karena faktor antropogenik, yakni konversi lahan mangrove menjadi tambak oleh masyarakat pesisir yang menyebabkan penggerusan pantai terus terjadi di kawasan ini, karena tidak adanya penghalang ombak, sehingga intrusi air laut menjadi tinggi dan terjadi banjir rob yang menyebabkan kerugian besar bagi warga yang sebagian besar memiliki mata pencarian sebagai petani tambak. Hasil penelitian ini menunjukkan bahwa kondisi mangrove di Desa Pantai Bahagia dikategorikan rusak parah dan kondisi biodiversitas yang rendah, sehingga urgensi untuk melakukan rehabilitasi tergolong tinggi. Hingga tahun 2018 sudah mulai muncul partisipasi masyarakat dalam merehabilitasi hutan mangrove, namun masih tergolong rendah dan belum dapat menandingi laju kerusakannya. Karenanya, dilakukan studi pada 30 masyarakat Desa Pantai Bahagia yang memiliki kepedulian dan tingkat partisipasi mengelola mangrove yang tinggi untuk menganalisis faktor-faktor yang dapat meningkatkan partisipasi masyarakat secara keseluruhan, serta menyusun strategi peningkatan partisipasi masyarakat dalam merehabilitasi mangrove Desa Pantai Bahagia.

ABSTRACT Aquatic and terrestrial ecosystems along the northern coastline of Java Island form a mangrove ecosystem into an ecosystem rich in interacting biodiversity, one of which is in Pantai Bahagia Village in Muara Gembong District, Bekasi Regency, West Java. In fact, from 1999 to 2014, mangrove forests in this village continued to experience degradation due to anthropogenic factors, namely the conversion of mangrove land into ponds by coastal communities which caused coastal erosion to continue to occur in this region, due to the absence of wave barriers, so that seawater intrusion became high and there was a tidal flood which caused huge losses for residents who mostly had livelihoods as pond farmers. The results of this study indicate that the mangrove conditions in Pantai Bahagia Village are categorized as severely damaged and have low biodiversity conditions, so the urgency to carry out rehabilitation is classified as high. Until 2018 community participation has begun to emerge in rehabilitating mangrove forests, but is still relatively low and has not been able to match the rate of damage. Therefore, a study was conducted on 30 Pantai Bahagia villagers who have a high level of care and participation in managing mangroves to analyze factors that can increase overall community participation, and develop strategies to increase community participation in rehabilitating mangrove Pantai Bahagia Village.

"ABSTRACTMangrove merupakan vegetasi yang hidup di daerah pesisir dan berhubungan langsung dengan keadaan dan kondisi perairan laut. Umumnya, tumbuh di daerah tepi pantai, muara, dan sungai. Penelitian ini bertujuan untuk memahami sebaran mangrove berdasarkan kondisi fisik perairan dan melihat luasan mangrove, serta mengaitkannya dengan kondisi hutan mangrove. Penelitian ini menggunakan Landsat 8 dengan software ArcMap 10.1 untuk mengindetifikasi sebaran mangrove dan metode yang digunakan adalah Normalized Difference Vegetation Index (NDVI) untuk melihat kerapatan vegetasi mangrove. Kondisi fisik perairan yang digunakan antara lain: salinitas, suhu permukaan air laut, pH air, substrat tanah, dan pasang surut, sedangkan kondisi hutan mangrove yang diteliti antara lain: kerapatan, ketebalan, dan spesies mangrove. Sehingga dengan demikian, penelitian ini dapat mengaitkan kondisi fisik perairan dan kondisi hutan mangrove dengan sebarannya. Hasil penelitian ini menunjukkan bahwa hutan mangrove Bojongsalawe memiliki suhu permukaan yang lebih tinggi dibandingkan dengan hutan mangrove di Batukaras dan Nusawiru karena populasi mangrove yang lebih sedikit dibandingkan dengan kedua hutan mangrove lainnya, namun hutan mangrove Bojongsalawe dan Nusawiru memiliki pH yang lebih tinggi dengan nilai kisaran antara 6,6-6,9 dibandingkan dengan hutan mangrove Batukaras yang memiliki nilai kisaran antara 6,3-6,6. Hal ini dikarenakan hutan mangrove Bojongsalawe dan hutan mangrove Nusawiru berada di muara yang mengalir menuju Sungai Cijulang dan anak sungai Cialit.

ABSTRACTMangrove is a vegetation that live in the coastal region and directly related to the circumstances and condition of the waters of the sea. Generally, growing in coastal areas, estuaries, and rivers. This research aims to understand the distribution of mangroves on the basis of the physical condition of waters and view the mangrove area, as well as associated it with the conditions of the mangrove forests. This research uses Landsat 8 with ArcMap software 10.1 for mangrove and distribution mengindetifikasi method used is the Normalized Difference Vegetation Index (NDVI) to see mangrove vegetation density. The physical condition of waters which are used, among others: salinity, surface temperature of sea water, the pH of the water, the soil substrate, and ups and downs, while the condition of the mangrove forests that are examined include: density, thickness, and mangrove species. This study can relate the physical condition of the waters and the condition of the mangrove forest to its distribution. The results of this study indicate that Bojongsalawe mangrove forest has a higher surface temperature compared to mangrove forests in Batukaras and Nusawiru because the mangrove population is less than the other two mangrove forests, but the mangrove forests of Bojongsalawe and Nusawiru have a higher pH with a range between 6,6-6,9 compared to Batukaras mangrove forest which has a range between 6.3-6.6. This is because the mangrove forests of Bojongsalawe and Nusawiru mangrove forests are in the estuary which flows towards the Cijulang River and the Cialit tributary."
