Abstract

Pantai Labu merupakan daerah yang terletak di Kabupaten Deli Serdang dan dimanfaatkan oleh masyarakat untuk penangkapan ikan menggunakan kapal, pemukiman serta aktivitas wisata. Adanya aktivitas tersebut diduga menyebabkan penurunan kualitas lingkungan mangrove yang berada di Pantai Labu. Nitrat dan Fosfat merupakan nutrien utama yang menentukan kestabilan pertumbuhan vegetasi mangrove. Akibat penurunan kualitas lingkungan, maka akan mempengaruhi distribusi nitrat dan fosfat yang dapat mempengaruhi pertumbuhan mangrove tersebut. Penelitian ini bertujuan untuk mengetahui kandungan nitrat dan fosfat di substrat mangrove serta keterkaitannya dengan kerapatan mangrove. Penelitian ini dilakukan pada bulan September-Oktober 2019 dengan menggunakan metode purposive sampling pada 5 titik stasiun. Hasil penelitian didapatkan nilai total kerapatan mangrove untuk tingkat pohon yaitu 2,89 Ind/m2,untuk tingkat pancang 1,75 Ind/m2 dan untuk tingkat semai 0,1 Ind/m2. Kandungan nitrat dalam sedimen berkisar antara 0,7-1,11 mg/kg dan kandungan fosfat dalam sedimen berkisar antara 2,5-2,8 mg/kg. Kandungan nitrat di subtrat yang didapatkan dalam penelitian ini termasuk ke dalam kategori rendah. Kandungan fosfat di subtrat yang didapatkan dalam penelitian ini termasuk ke dalam kategori rendah. Keterkaitan nitrat dengan kerapatan mangrove yang didapatkan sebesar 98% yang berarti nitrat memiliki pengaruh yang sangat besar dengan kerapatan mangrove, sedangkan keterkaitan fosfat dengan kerapatan mangrove yang didapatkan adalah sebesar 20% yang berarti fosfat memiliki pengaruh yang kecil (sedikit) dengan kerapatan mangrove.Pantai Labu is an area located in Deli Serdang Regency which is used by the people for fishing using ships, settlements and tourist activities. The existence of these activities is thought to cause a decrease in the quality of the mangrove environment on Pantai Labu. Nitrate and Phosphate are the main nutrients that determine the stability of mangrove vegetation growth. As a result of environmental degradation, it will affect the distribution of nitrates and phosphates which can affect the growth of mangroves. This study aims to figure out the nitrate and phosphate content in the mangrove substrate and its relation to the density of the mangrove. This research was conducted in September-October 2019 using a purposive sampling method at 5 station points. The results obtained total value of mangrove density for tree level is 2.89 Ind/m2, for the sapling level 1.75 Ind/m2 and for seedling level 0.1 Ind/m2. Nitrate content in sediments ranged from 0.7-1.11 mg/kg and phosphate content in sediments ranged from 2.5-2.8 mg/kg. The nitrate and phosphate content in the substrate obtained in this study was the low category. Result of statistical analysis of the relationship between nitrate and mangrove density was 98%, which means that nitrate had a very big effect on mangrove density, while the relationship between phosphate and mangrove density was 20%, which meant that phosphate had a small effect (a little) with mangrove density.

Abstract

Pasar Sorkam Beach, Binasi Village is an area with many large coastal areas with an area of ​​3.85 km2, with a population of 1262 people and an average livelihood as a fisherman, with a total catch of 40234.7 tons. Based on information from POKMASWAS and temporary fishing groups, there are problems, that is the decline in fish catches due to damage to the ecosystem caused by illegal fishing and fishing that is Harmful to the environment, so that a solution is needed to solve this problem, namely by making fish aggregate device (FAD) called Rumpon that support sustainable fisheries so that it is in line with Sustainability Development Goals (SDGs) number 14. The method of implementing this activity is the educational method with demonstrations and counseling through four stages, preparation of activities, field practice, socialization, monitoring and evaluation. The results and discussions obtained were that preparation of activities was carried out after site surveys and literature studies with experience in using Rumpon, construction planning and determining the release of Rumpon, field practice was carried out by releasing Rumpon by all activity participants and accompanied by the Indonesian Navy, the release is intended as a new fishing ground for fishermen, socialization of activities attended by all participants, monitoring and evaluation, monitoring through the head of POKMASWAS, evaluation using a questionnaire with 15 questions about the condition of fishermen, community service activities are conducive and fishing group mitra are very enthusiastic about this activity.

Abstract

Highlight Calculated and assested the percentage of live coral coverIdentified reef fishes and calculated fish abundanceMeasured physical and chemical oceanography parameter Analyzed carrying capacity and suitability of Unggeh Island for tourism utilization especially marine diving and snorkeling.AbstractUnggeh Island located in the administration of the Village Sitardas Badiri District, Central Tapanuli Regency into a marine tourism area. The development of marine ecotourism Unggeh Island is an alternative to the economic improvement of so- ciety. This study aims to assess the potential of coral reef ecosystem in the form of percentage of life form coral, coral species and species and abundance of reef fish found in Unggeh Island waters of Central Tapanuli Regency and to analyze the suitability of coral reef ecosystem in Unggeh Island for tourism utilization es- pecially marine diving and snorkeling. Coral reef community data collection was done by using SCUBA divers equipment, in identifying The coral community used underwater photo transect (UPT) method, while coral fish diversity was observed by underwater visual census (UVC) method. Physical and chemical oceanography parameter data such as temperature, salinity, pH, current, transparency and DO are performed at each observation station. The survey results of coral reef observation at four stations showed different results. Percentage of live coral cover of station 1 to 4 were 25.40 %, 12.33%, 28.53%, and 25.53 respectively. Therefore, reef fishes found 36 species that consist of ten families and 423 individual fishes. The results showed that Unggeh Island was suitable (S2) for diving and snorkeling activities, with the carrying capacity was 3.054 persons/day.

Abstract

The coastal area of ​​Serdang Berdagai district, Bandar Khalifa sub-district, has a population of 25,857 people With 80% working as fishermen, which is still dominated by small-scale fishing, This coastal area has a high diversity of mangroves, However, based on a survey, the mangrove ecosystem in this location has begun to be damaged and competition with trawl fishing boats, damage and competition result in a decrease in the catch of small fishermen, so that the optimization of the ecological area needs to be done through the implementation of mangrove rehabilitation, nurseries and the application of fishing aids, with the aim of increasing the catch of fishermen, The approach method used demonstration and counseling methods, socialization of activities by delivering material to mitra in the form of sharing sessions, followed by field practice with mangrove nurseries carried out by the community service team, Ministry of Marine Affairs and Fisheries extension and fishing mitra POKMASWAS Elang Putih and fishermen group KUB Bina Usaha Mandiri
