The research was conducted from March to June 2015 in the laboratory of Marine Science of the faculty of FPIK UNPAD. The sampling of Gracilaria sp. was taken from a seaweed farming in Kalianda, Bandar Lampung Province. The aim of conducting this research is to investigate the effect of Ammonium addition to Gracilaria sp. on the absorption process of Mercury. The proportion amount of 10.5-gram Gracilaria sp. used in this research is mixed with 3 litres seawater media. The research method was performed using Completely Randomised Design (CRD) with four treatments and three replications. Parameters for the measurements are water quality, reduction of mercury and ammonium concentration, bio concentration factor, and growth rate. The research was designed with an addition of 0.05 ppm Mercury in all treatments, where each treatment was given different concentrations of Ammonium as follows: treatment A: 0.5 ppm, treatment B: 1 ppm, and treatment C: 1.5 ppm, with no addition of Ammonium for Control Treatment. The result of this research showed that treatment C hit the highest absorption level in absorbing Ammonium and Mercury with their concentrations of 95.98% and 56.44% respectively in seawater media, while the concentration of Mercury in the Gracilaria sp. biomass was measured 0.47 ppm.Keywords: Absorption, Ammonium, Gracilaria sp., Phytoremediation, Mercury.

ABSTRACTPangkil Village is one of the villages located in Teluk Bintan District, Bintan Regency, Riau Islands Province which has potential for seagrass resources, especially the type of Enhalus acoroides. This study aims to examine the growth response of seagrass E. acoroides to differences in water quality in the waters of Pangkil Village. This research was conducted in September to November 2020. The stations in sampling site was determined by purposive sampling method, there were 4 sampling stations, namely: shipping activity, boat mooring activities, catching shellfish activity, and no activity of the community (mangrove area). The measurement of the growth rate of seagrass leaves was useds the marking method on young and undamaged leaves using a cable tie. Leaf growth was observation for 60 days with intervals of 15 days. The water quality in Pangkil Village Waters meets quality standards. The highest density value of Enhalus acoroides seagrass was in the shipping activity of 64.67 ind/m2. The highest growth rate of seagrass after 60 days on Enhalus acoroides seagrass leaves was in the boat mooring activity area with value 0.401 cm/day, while the lowest growth rate of Enhalus acoroides leaves was in the area of catching shellfish activity of 0.383 cm/day.Keywords: Enhalus acoroides. density, growth rate, Pangkil WatersABSTRAKDesa Pangkil merupakan salah satu desa yang berada di Kecamatan Teluk Bintan, Kabupaten Bintan, Provinsi Kepulauan Riau yang memiliki potensi sumberdaya lamun, khususnya jenis Enhalus acoroides.

ABSTRACTBanggai cardinalfish (Pterapogon kauderni) has been introduced and has spread around Bokori Island, Southeast Sulawesi. This study aims to determine the population of P. kauderni in the waters of Bokori Island from the aspect of density, body length distribution, and microhabitat. This study used the belt transect method at three observation stations, with three replications for each station to observe of the fish population’s density. Overall, fish density is in the range of 13.67±1.53 individuals/100 m2 to 36.67±4.62 individuals/100 m2. The distribution of fish body size (Total Length/TL) that is observed varies moderately, ranging from 0.5 cm to 5.5 cm. Microhabitat preferences that are associated with fish include sea anemones (57.3%), coral Millepora (28.5%), and sea urchins Diadema (14.2%). Despite the presence of other fish species in the same microhabitat, P. kauderni coexists with other fish species peacefully.Keywords: Pterapogon kauderni, density, body length, microhabitatABSTRAKIkan Banggai cardinal (Pterapogon kauderni) telah diintroduksi dan telah menyebar di sekitar Pulau Bokori, Sulawesi Tenggara.

ABSTRACTThis research is based on the importance of the role of mangroves to the needs of coastal ecosystems, because they have high economic and ecological value. The main problem in the mangrove ecosystem is the occurrence of logging and degradation for several purposes and purposes. Therefore, it is necessary to understand and understand the importance of rehabilitation and restoration, especially for the Bintan Regency area.

摘要红树林具有很高的经济和生态价值，对沿海生态系统的需求具有重要的作用。红树林生态系统的主要问题是出于多种目的而发生的伐木和退化。因此，有必要了解和理解重建和恢复的重要性，特别是对于民丹摄政地区。目前进行的修复都是采用苗木法。利用Rhizophora sp.研究民丹县丹绒美拉和丹绒美拉沿海地区红树林恢复活动的存活率和社区对红树林恢复活动的认识水平。本研究采用目的性抽样方法。根据已实施的政府方案中选择的抽样点确定抽样点，同时考虑到代表每个地区的能力。监测采用样地进行，其中一个样地将以3x1模式种植33棵红树林，每个区域将监测10个样地。结果表明，各地区丹戎美拉和丹戎皮索的存活率分别为58%和85%，均取得了较好的效果。而公众的意识水平也相当不错，占73.4%。关键词:意识，红树林，恢复，民丹岛[关键词]:红树林，红树林，恢复，民丹岛[关键词]:红树林，红树林，恢复，民丹岛[关键词]:红树林，红树林，生态系统，生态系统，生态系统，生态系统红树林生态系统的研究:红树林的生态系统。Maka dari itu, perlunya memahami dan mengerti akan pentingnya rehabilititasi dan restorasi terutama untuk kawasan daerah Kabupaten Bintan。【译】植物性植物，植物性植物，植物性植物。Kegiatan Restorasi红树林paada wilayah Tanah Merah dan Tanjung binau, Kabupaten binau, menggunakan cara pembenihan, Rhizophoran sp.
