Abstract

Mangrove forests existed in Village Belawan Sicanang have been many experienced land conversion as embankment and settlements. These conditions led to degradation in habitat quality. The research aimed to know mangrove species composition and to know mangrove community structure. The research took place in May  June 2016. The method used in the determination of the location is purposive sampling and divided into 3 stations based on different activities. Analysis of mangrove vegetation derived mangrove density, relative density, mangrove frequency, relative frequency, dominance, relative dominance, importance value index, diversity index, and evenness index. The results showed that the composition of mangrove species found eleven species of true mangroves that are Avicennia alba, Avicennia marina, Bruguiera gymnorrhiza, Bruguiera hainessii, Ceriops tagal, Nypa fruticans, Sonneratia alba, Sonneratia caseolaris, Xylocarpus granatum, Rhizophora apiculata dan Rhizophora mucronata. The mangrove forest located in Village Belawan Sicanang is classified on very tight criteria where mangrove density ≥ 1500 ind/ha, the relative dominance ≥ 75%, and the mangrove community were in stable condition.Keywords : Mangrove, Species Composition, Community Structure

Abstract

Dusun Paluh Merbau is one of 13 villages at Desa Tanjung Rejo Kabupaten Deli Serdang with covering area of 4.114 Ha. Rapid population growth directly caused a pressure on natural resources. The purpose of this research was to describe the causes of mangrove ecosystem damage and mangrove ecosystem management strategy at Dusun Paluh Merbau Desa Tanjung Rejo Kabupaten Deli Serdang. This research was held from April to Mei 2016. It used descriptive qualitative method and SWOT Analysis for sustainable mangrove ecosystem management strategy. Mangrove species found were Rhizophora apiculata, Bruguiera cylindra, Avicennia marina, and Lumnitzera racemosa. Activities at mangrove ecosystem caused some damages in Dusun Paluh Merbau such asdeveloping agriculture, aquaculture, settlement and it’s supported by weakness of law enforcement. SWOT analysis quadrant for mangrove ecosystem management at Dusun Paluh Merbau is in 3rd quadrant that means this village has opportunity butit hasthe internal weakness too, so that difficult to achieve profitable opportunity. Turn Arround Quadrant brings in the W-O strategy as the priority alternative strategy for mangrove ecosystem sustainable management; socializing or awareness to the community about the importance of integrated sustainable natural resources management (W1, W2, W3, W4, O1, O2, O3, O4) gained the highest score 3,11.Keywords : Dusun Paluh Merbau, Management Strategy, Mangrove, SWOT Analysis.

Abstract

Mangroves serve as a habitat organism aquatic, one of which is Macrozoobenthos. The abundance of Macrozoobenthos are very dependent on the power of tolerance to environmental changes. This research was aimed to analyzed density of Mangrove and how a relation with abundance of macrozoobenthos in the coastal village of Jaring Halus. This research is done in December 2016 to Januari 2017. The study used purposive random sampling method by taking and observation of mangrove vegetation, abundance of macrozoobenthos, and measurement of water quality parameters. Data analysis included analysis of mangrove vegetation, analysis of macrozoobenthos, analysis of water quality and analysis of the substrate. Found 11 species of mangrove with density at Station I 5.166 ind/ha, Station II 4.066 ind/ha and Station III 1.567 ind/ha. For macrozoobenthos found 16 species are the research site at Station I 249 ind/m2, Station II 167 ind/ m2 and Station III 147 ind/ m2. The Relationship of Mangrove’s Density and Macrozoobenthos Abundance in the coastal village of Jaring Halus indicated by the equation y = 0,0808x + 24,225 with R2 of 0,7526 and r = 0,867. And the Relationship of organic materials and Macrozoobenthos Abundance indicated by the equation y = 93,20 x – 323,8 with R2 of 0,776 and r = 0,881. From the result of data analysis relationship are very stong and real.Keywords : mangrove, macrozoobenthos, Jaring Halus Village, water quality

Abstract

Tilavia is favorite fish consumsion by the people of indonesiaand it is very easy to cultivate because it has a sufficient level of the prospective development. The feed is a very important factor in the process enlargement fish. This research was conducted to determine the effect of feeding a mixture of pellets water kale on the growth of tilapia. Container maintenance of tilapia used mine concrate pols with 1 x 1 x 1 M2 of size and 50 liters of volume water for each pool.This research was conductedin August – November 2015 in the Binjai Town. The method user completely randomized design with treatment of pellets feed was + kale (1:3). The P1 treatment showed the best daily length growth and daily weight growth. The final result obtained the length of P1 treatment was 11,76 cm, P2 treatment was 10, 92 cm, P3 treatment was 9, 97cm, and the weight of P1 treatment was 13,15 gr, P2 treatment was 11,21 gr, P3 treatment was 9,66 gr. The total feed used 3966.9 gr.Key Words : Tilapia (Oreocromis niloticus), Growth, Water Kale (Ipomea aquatica)

Abstract

The research about Aquatic Primary Productivity needs to be done, it is because by knowing the value of primary productivity in the waters, will be known fertility waters. The research was done in May 2016. The aim of this research was to knowing the value of Primary Productivity of phytoplankton in Betimus River at Deli Serdang and to analyze its relationship with the physical and chemical factors. The sampling station was determinated by Purposive sampling method. Samples were collected from 3 sampling station. The result showed that of primary productivity range from 100,096-250,240 mg C/m3/day, the highest value was at station 3 and the lowest value was at station 1. Analysis of pearson correlation shows that the factors which have a very strong relationship with the primary productivity are DO, phosphate, nitrate, and the abundance of phytoplankton, factor which has a strong relationship with pimary productivity is temperature, and factor which has a moderate with pimary productivity is pH.Key Words: Primary Productivity, Purposive sampling method, Phytoplankton.

Abstract

The research about parameter analysis of physics and chemistry is one way to know of water quality and the value contained in the water bodies. The aim of this research paper is to learn the value of physics and chemistry content on the water and status water quality based on regulations PP 82 year 2001 in Artificial Lake Perumnas Griya Martubung, Medan City. The research done by using porpusive sampling method. Determination of water quality status on the lake using STORET method and table of water quality standard from regulations PP 82 year 2001. The measurement result shows that the physical and chemical parameter of water that isn’t pass the quality standard was temperature (32.33°C); brightness (15-18 cm); TSS/Total Suspended Solid (256 to 188 mg/L); the degree of acidity/pH (6.5 mg/L); nitrate/NO3-N (0.2 to 0.36 mg/L); phosphate/P (0.81 to 1 mg/L) and which parameter passed of quality standard is Dissolved oxygen/DO (0.26 to 0.36 mg/L); Biochemical Oxygen Demand/BOD (17 to 18.75 mg/L); total ammonia / NH3-N (8.5 to 8.9 mg/L); and oils and fats (4.5 to 8.5 mg/L). Quality status of water Artificial Lake in Griya Martubung Housing was heavily polluted for standard quality on class III water.Keywords: Artificial Lake Perumnas Griya Martubung, Water Quality, method STORET
