Abstract

Community activity gives influence to ecosystem condition in river estuary area in Desa Pintu Air and potentially affect water quality, characteristic and sedimentation rate, and abundance of marine biota especially macrozoobenthos. The study was conducted from May to July 2017 at Pintu Air Village, Langkat Regency, North Sumatra Province. The study was conducted by purposive sampling. The result showed that sedimentation rate in Desa Pintu Air estuary Station I was 3491,98 gr/ m2/day, Station II was 389,10 gr/m2/day, Station III was 369,15 gr/m2/day, Station IV equal to 1576,14 gr/m2/day, and Station V was 5353,51 gr/m2/day. Abundance of macrozoobenthos in Station I was 18 ind/m2 Station II of 17 ind/m2, Station III was 13 ind/m2, Station IV was 22 ind/m2 and Station V was 7 ind/m2 . The value of Diversity Index (H ') Station I was 4,08 Station II was 4,65 Station III was 4,83 Station IV was 5,12 and Station V was 4,07. Dominance index (C) Station I was 1,01 Station II was 0,32 Station III was 0,47 Station IV was 0,49 and Station V was 0,77.

Abstract

Kampung Nipah Sei Nagalawan Village is a marine biota producer area such as aquatic macrofauna and mangroves. Villagers of Sei Nagalawan generally have livelihoods as fishemen. Their lives depend on seafood obtained through both fishing and cultivation. So the need to increase the potential problems against the biota. However, from excessive community activity on mangroves can damage the ecosystem so that there is a physical decline and water quality degradation of the mangrove ecosystem. This study aims to analyze the level of abundance, biomass, diversity and evenness and to analyze the pattern of the spread of aquatic macrofauna around the mangrove. This research was conducted in March – May 2017. This research was conducted by survey method and sampling was done by purposive sampling method. The results showed that the condition of aquatic macrofauna in the mangrove area of Kampung Nipah Sei Nagalawan was rare and the macro-aquatic macrofauna pattern was very minimal due to the large number of mangrove land that was damaged to reduce the habitat for the biota.Keywords : Mangrove, Aussiatic Macrofauna, Nipah Villege, Sei Nagalawan Village, Serdang bedagai

Unggeh island is administratively located in Sitardas Village, BadiriSubsistrict Tapanuli Tengah Regency. Exposure to the sea floor south, west, and north of Unggeh Island is overgrown by coral reef. Coral reef ecosystem is one of the coastal resources that are highly vulnerable to damage, especially those caused by human behavior. This research held on April 2017. This research aimed to know percent cover and the condition of coral reef ecosystem in the Unggeh Island. This research using Underwater Photo Transect (UPT) method. From this research results obtained 17 types of coral lifeform namely Acropora Branching,Coral Branching, Coral Encrusting, Coral Mushroom, Soft Coral, CoralSubmassive, Coral Massive, Makro Algae, Halimeda, Coral Foliose, Dead Coral with Algae, Dead Algae, Sand, Silt , Rubble, Turf Algae and Others, with were dominated by Dead Coral with Algae (DCA). The cover percentage of coral in the first station was 25,4 %, in the second station was 12,33 % and in the third station was 28,54 % with an average value was 22,09 % and coral reef condition in Unggeh Island was bad status.Keywords: Coral Reef Ecosystem, Unggeh Island, Percentage of CoralReef, Underwater Photo Transect (UPT)

Abstract

One method to find out food and feeding habits of mangrove crabs (Scylla serrata) is to examine what types of foods contained in the stomach of mangrove crab and feeding period of mangrove crab. The purpose of this study are the type of food, to know the time period of feeding crab mangrove and to determine the effect of time on the mangrove crab in the mangrove ecosystem in Kampung Sentosa. Characteristic observed food type, meal time mangrove crab. Analysis of food data and feeding habits method to research data by using the formula FK, E, ISC and IP. The results of data analysis found the type of mangrove crab food in the form of shellfish, shrimp, fish, moss and mangrove leaves. Mangrove crabs are more active to find food at night, especially from 12 am to 12 pm. Periods of mangrove crabs do not depend on time because they can find food anytime.Keywords: Food, Mangrove Crab, Sicanang Belawan, Feeding Habits

Abstract

Ecosystem of mangroves forest in the District of Percut Sei Tuan has a number of conversion that effected by aquaculture activities namely shrimp farming, then plantation activities such as palm oil plantation. Furthermore, the most utilization of mangrove that is done by society such as wood fuel and charcoal production. It causes permanent mangrove destruction and reduction in mangrove area which is lead to decrease in ecological function and benefit of mangrove ecosystem. The purpose of this study is to determine the condition and the dominant species of mangrove, hence how the coastal society effort in dealing with mangrove forest destruction. This research was conducted in May - June 2017. The research was conducted by survey method and purposive sampling. The result showed that mangrove condition in Percut Sei Tuan Subdistrict of Deli Serdang Regency was in rare state. And also found the most widely Plants of Nipah up to 2.000 Tree/ha. Condition of water parameters (temperature, salinity, pH) fulfill the quality standard of Decree of LH No. 51 of 2004. The value of mangrove landform changes as much as 64% which is used as palm oil plantation and 36% used as pond area and the utilization of mangrove as fishing (fish, shrimp, crab, et all) and charcoal fuel which resulted in decreasing of mangrove land in Percut Sei Tuan Subdistrict of Deli Serdang Regency of North Sumatera.Keywords : Mangrove, Transformation area, Sub-district Percut Sei Tuan, Deli Serdang district
