The environments that receive the greatest impact from waste generation are coastal and marine areas. This is because waste dumped in gutters and rivers will flow to coastal areas and the sea. One of the ecosystems that receives the impact of waste disposal is mangroves. Poka Village is a coastal area in Inner Ambon Bay with a fairly dense population. One of the vegetation that is an important concern for people living in this area is mangroves. This is because there was sudden damage to mangroves in May 2022 due to oil waste. Quick and appropriate action needs to be taken immediately to preserve the mangrove ecosystem in Poka Village. Therefore, it is necessary to carry out clean-up actions and plant mangrove seedlings in Poka Village in the damaged mangrove ecosystem. The service activity took place in Poka Village on May 11 2023. The service was carried out together with the NGO Moluccas Coastal Care, the State Electricity Company (PLN), the Army, students and lecturers of Marine Science at Pattimura University and also the community in Poka Village. The activity began with a gathering at the mangrove planting location at 08:00 WIT. After that, clean up the rubbish and cut down the dead mangrove trees. Then proceed with planting Rhizhopora sp mangrove seedlings. Planted mangrove seeds can grow well after one year. This indicates that environmental conditions such as substrate and water are in good condition and suitable for the growth of mangrove seedlings. Future monitoring activities need to be carried out to maintain the successful growth of mangrove seedlings from year to year.

Abstract Background : Mangrove is a complex ecosystem that is unique and has a large enough carrying capacity for the surrounding environment. Mangrove ecosystems have ecological and economic functions. The ecological function is to protect the coastline, habitat, feeding ground, spawning ground and nursery ground for aquatic biota as well as controlling the microclimate. Meanwhile, its economic function is to produce raw materials for charcoal and medicines. Mangrove ecosystems have high biological productivity, but about 5% are consumed directly by terrestrial animals, and as much as 95% as debris from litter or leaf fall. In the Dokyar Hamlet area of Kaibobu Village, the mangrove forest ecosystem plays a very important role in maintaining the environmental balance in the area, because it is close to the villages. This area has unspoiled mangrove forests. However, there is no information regarding the types of mangroves in Dokyar Hamlet, Kaibobu Village, so it is necessary to conduct research on an identification of mangrove species found in the waters of Dokyar Hamlet, Kaibobu Village. Methods: This research was conducted in October 2020 with a sampling location taking place in Dokyar Hamlet, Kaibobu Village, Kairatu District, West Seram Regency, Maluku. The observation method used in the research and the sampling of mangroves used the line transect method, while the identification of mangroves was by observing the roots, stems, leaves, flowers and fruits. Results: Mangrove found 7 species from 6 genera: Bruguiera gimnorrhiza, Ceriops tagal, Nypa fruticans, Rhizophora apiculata, Rhizhopora mucronata, Sonneratia alba and Xylocarpus granatum Conclusion: The results of research in the mangrove ecosystem area of Dokyar Hamlet, Kaibobu Village, found 7 mangrove species belonging to 6 genera. Keywords: ecosystem, identification, mangroves

It is important to maintain a healthy marine ecosystem to support eco-friendly and sustainable fishery development. Implementation of Ocean Health Index (OHI) started globally in 2012, and it has been strongly recommended to be conducted at all levels: locally, nationally, and regionally. Indonesia has modified OHI for its national assessment, which its called Indeks Kesehatan Laut Indonesia (IKLI). IKLI has been estimated since 2020 and introduction applied at the sub-national level. This study is an attempt to implement IKLI in Maluku province with the main objective is to estimate score of a partial IKLI, based on clean waters (goal no. 9) and biodiversity (goal no. 10). Samples were taken from Ambon and Baguala Bays between June and September 2022. For clean water goals, the parameters used were concentration of phosphate, nitrate, silicate, dissolved oxygen (DO), pH, and the number of ports that implemented green principles. The parameters of water quality of silicate, DO and pH in those two bays are within the range of government-mandated standards, except for nitrate and phosphate concentrations which are not. For the biodiversity goal, the parameters used are the species composition of mangrove, seagrass, fish, and coral. The IKLI biodiversity score was low due to the high level of human activity pressure at the two selected study sites. This study demonstrates the applicability of the IKLI in a partial analysis, and its usefulness in highlighting existing data and knowledge gaps. The study suggests that a comprehensive IKLI assessment should be conducted in Maluku Province. Meanwhile to improve the national-level IKLI assessment, actions should prioritize improving water quality management, expanding marine protected areas, and monitoring coastal ecosystems, especially those heavily affected by human activities.KeywordsArchipelagonutrientOHIIKLI Maluku
