Siombak Lake is an artificial lake located in Kelurahan Rengas Pulau, Medan Marelan, is 18 km north of the center of Medan. Plankton is one of the main components in the food chain and food web. The purpose of this research is to know the diversity of plankton community, the value of water chemistry physics parameters, and the correlation between water chemical physics factor with plankton at Lake Siombak Medan Marelan Sub-district Medan City. The research was conducted at Siombak Lake in September 2015. Plankton and plankton water quality data including temperature, pH, brightness, dissolved oxygen (DO), BOD5, NH3, and phosphor grades were obtained from the field and analyzed in the laboratory. The method used in determining the sampling location for plankton sampling is "Purposive Sampling" at 5 (five) observation stations. The value of plankton diversity index obtained at Lake Siombak is Station 1: 3.05145, Station 2: 3.14593, Station 3: 3.10679, Station 4: 3.07244 and Station 5: 3.1212. Temperature, pH, BOD, Salinity, DO, Brightness are in the range of quality standards, while nitrate and phosphate exceed the quality standard.Keyword : Plankton, Physics - Chemistry of Water, Lake Siombak

Mangroves are an important part of determining conservation areas as well as determining zoning within conservation areas. Therefore, information on the status and distribution of mangroves is essential in managing conservation areas. This study was conducted in Taman Pulau Kecil, Central Tapanuli District. The data was collected in June 2019. The sampling sites consisted 26 points (1-15 at the Mursala Island and its surroundings and 16-27 in the Tapian nauli Bay (maindland)). The study revealed 17 mangrove species from 9 families consisted of 14 true mangroves and 3 associated mangroves namely pandan (Pandanus tectorius), waru (Thespesia populnea), and ketapang (Terminalia catappa). Analysis of the importance of mangrove species in Taman Pulau Kecil, Central Tapanuli district showed that Rizophora, Xilocarpus, and Bruguiera have a large influence and role in the mangrove vegetation community. Mangroves in conservation area at Taman Pulau Kecil were in the good category. However, the condition and status of mangroves in Tapian Nauli Bay had better condition with the density of 3.120 ind/ha while in Mursala Island and its surroundings with density of 2.356 ind/ha.Keywords: Mangrove, Marine Protected area, Mursala Island, Tapian Nauli BayABSTRAKMangrove merupakan salah satu ekosistem penting dalam penentuan kawasan konservasi serta dalam penentuan zonasi di dalam kawasan konservasi.

The Nias Islands are a group of islands located on the west coast of Sumatra. Nias Island is the main and largest island on the West Coast of Sumatra. Information on the distribution and potential status of mangroves in the Nias Islands has been reported, but it is limited to a narrow area and not yet comprehensive throughout the Nias Islands. This study aims to determine the distribution and ecological status of mangroves in the Nias Islands. The research location was divided into two observation areas, namely 15 points on Nias Island and 23 points on the southern part of Nias. The research was carried out in June 2019 and June 2021. Mangrove sampling was carried out using the "spot check" method which refers to Bengen (2004). The results showed that the mangroves found in the Nias Islands consisted of 22 primary mangrove species and 9 secondary mangrove species. Rhizophora apiculata, Rhizophora mucronata, and Xylocarpus granatum are the most abundant mangrove species and are commonly found in the Nias Islands. The thickness of mangroves in the Nias Islands ranges from 15 â€“ 880 m. The density of mangroves found reached 350-4,360 ind/ha. Mangrove cover reaches 0.08-31.62 m2/ha. The results of the analysis of the significant value of mangrove species show that Rhizophora mucronata and Rhizophora apiculata have a large influence and role in the mangrove vegetation community on Nias Island. Mangroves in the Nias Islands are categorized as damagedâ€“good. The good category was found in South Nias, Belukar Bay, and Bengkuang Bay, while the damaged category was found in Lahewa Bay and Dalam Bay
