Abstract

This research was conducted in May, 2017 located at Kelurahan Bagan DeliMedan Belawan Subdistrict Medan City North Sumatera Province. This studyaims to determine changes in income generated by mangrove crab fishermenbefore and after the occurrence of mangrove land damage and the efforts ofmangrove crab fishermen to increase income due to damage to mangrove inKelurahan Bagan Deli. The method used in this study is survey method with 36household as respondents detemination by random sampling.The results showed that there was a decrease in income from the catch offishermen of mangrove crabs by IDR 1,702,219.44 per month (54.85%) aftermangrove damage, from IDR 3,103,044.44 to IDR 1,400,825.00 per month andare statistically significant. The efforts of mangrove crab fishermen to increaseincome are diversification of livelihoods, the addition of fishing gear such astraps, fishing rods and nets, mobilizing the role of family members and savingmoney.Keywords: mangrove damage, income, fisherman, mangrove crab

Abstract

Samsam Swamp is a lowland swamp that receives water from the Samsam River during the rainy season. To understand the trophic status of Samsam Swamp, a present study based on the concentration of chlorophyll-a was conducted in March-April 2016. The method used was a survey method. There were four sampling stations namely Station 1, Station 2, Station 3 and Stasion 4. Samplings were conducted 3 times, once a week. Results shown that concentration of chlorophyll-a was 4.05 – 7.69 μg/L; temperature 28 – 33⁰ C, transparency 28 – 46.9 cm, water pH 4 – 5, orthophosphate 0.37 – 0.65 mg/L, nitrate 0.33 – 0.63 mg/L, dissolved oxygen 3.69 – 4.93 mg/L, free carbon dioxide 4.00 – 11.99 mg/L and depth 39 – 170 cm. Based on the concentration of chlorophyll-a, Rawa Samsam is classified as mesotrophic waters.Keywords: Lowland Swamp, Samsam Swamp, Chlorophyll-a, Trophic Status

Abstract This study aims to determineof long storage at room temperature to the quality of seaweed(Eucheuma cottonii)jamwhich fortifiedChlorella sp.powder. The method used in this research is experimental method with Randomized Block Design (RBD) non factorial, the treatment is different concentration of Chlorella sp. powderthat is C0 (0 gr of Chlorella sp. powder) as a control, C1(1 gr ofChlorella sp. powder) and C2 (1.5 gr ofChlorella sp. powder), while as a group is a long storage, which is H1 (0 day), H2 (10 days), H3 (20 days), and H4 (30 days), by using a glass bottle. The tested parametersare organoleptic (appearance,odor, texture and flavor),chemical analysis (water and protein content) and Total plate count (TPC). The results showed that the effect of long storage at room temperature to the quality of seaweed(Eucheuma cottonii) jam which fortified Chlorella sp. powder give a real effect at 95% confidence level against organoleptic (appearance 7.02%, odor 6.80%, texture 6.84%, and flavor 6.94%), chemical analysis(water content 31.08 %, protein content 6.26%) andTotal plate count4.10 cfu/g, and can be accepted by consumers with the best storage durationis H0 - H10 at room temperature storage.  Keywords: jam, seaweed, storage, Chlorella sp

Abstract

The aim of the research was to determine the effect of fortification Chlorella sp. which can be used as a substitute for urea in the manufacture of nata de seaweed and the quality of nata de seaweed produced from fortified Chlorella sp powder. The method used was this research is experimental method that is making nata de seaweed which fortified with Chlorella sp. different amount . The design used was non-factorial complete randomized design (CRD) which consisted of 4 levels, namely NR0 (urea 5g), NR1 (2g Chlorella), NR2 (4g Chlorella) and NR3 (6g Chlorella). The parameters used were sensory evaluation and procsimate evaluation. Based on the results of this study it can be concluded that use of Chlorella sp. can be used as a substitute for urea in the manufacture of nata which has been prohibited its use. The best treatment of the four treatments used was by using Chlorella sp. as much as 6g, with average organoleptic value (color 3,76, odour 3,66, texture 4,10 and taste 3,93), water content 87,75%, ash 0,21%, protein content 1,56 %, And 0.34% crude fiber content.Keywords: Seaweed, Nata, Chlorella, Urea

Abstract

ABSTRACT Epi-macrozoobentos are animals that live on the surface of a water base substrate and are larger than 1 mm in size. This study aims to determine the structure of epi-macrozoobenthic community which includes: species composition, abundance, diversity, uniformity, dominance and the relationship between the total organic content of sediment to epi-macrozoobenthic abundance. Environmental parameters measured include physics-chemical parameters of waters (temperature, velocity, salinity, pH and DO) as life-supporting factors of epi-macrozoobentos. The species of epi-macrozoobentos in the waters of Pandan Island were found to be 17 species from 14 families, 7 classes and 14 genera with species composition ie 74% Gastropoda class, Echinoidea 9.6%, Malacostraca 8.6%, Bivalva 3%, Asteroidea 2.6 % and Holothuridea 2.2%. Epi-macrozoobenthic abundance in Pandan Island waters ranged from 4.5 to 6.6 ind / m2 with an average of 5.3 ind / m2. The diversity index values ranged from 2.45 to 2.86, the dominance index ranged from 1.14 to 1.21 and the uniformity index ranged from 0.62 to 0.81. The total organic content of sediments ranged from 1.70 to 2.57%. Based on the diversity index (H ') of Pandan Island waters classified as moderate and medium diversity. In general, the state of the chemical physics of Pandan Island waters can still support the life of epi-macrozoobenthic organisms.Keywords: Community structure, epi-macrozoobentos, Organic matter, Pandan Island.

Abstract

This research was conducted on June until August 2016 in Parasites and Fish Diseases Laboratory, Faculty of Fisheries and Marine science, University of Riau, Pekanbaru. The aim of this research was to determine leucocyte differentiation of Pangasius hypopthalmus that were feed with curcumin extract from Curcuma domestica V. This research used five treatment such as; Kn (negative control): that were feed without curcumin extract and were not infected with A. hydrophila, Kp (positive control): that were feed without curcumin extract and infected with A. hydrophila, P1: feed with curcumin extract in 0,3g/kg, P2: feed with curcumin extract in 0,5g/kg and P3: feed with curcumin extract in 0,7 g/kg. Fish reared in an aquarium the size of 40x30x30 cm with stocking density 10 fish / aquarium, feeding as many as 10% of body weight and do 3 times a day. Pisciculture carried out for 30 days and after that fish infected with Aeromonas hydrophila. The results shown that P3 (feed with curcumin extract in 0,7 g/kg) were the best treatment with lymphocytes 83,00%; monocytes 5.33%; neutrophils 3,67%; thrombocyte 8.00%; total leukocytes 12,01x104 cell/mm3; and fagocyte index 58,33.Keyword: Leukocytes, Pangasius hypopthalmus, Curcuma domestica V, Curcumin Extract

Abstract

The objective of the research is to find out water quality condition in most coastal water in East Sungaitohor especially turbidity and its effect toward water primary productivity and its nutrient. This research has been conducted in Sungaitohor waters, district of Kepulauan Meranti. The methods used is purposive sampling. Sampling has been conducted on March 4th, 2017 and nitrate, phospate analysis and turbidity conducted in Marine Chemistry Laboratory and phytoplankton identification has been conducted in Marine Biology in March 10th, 2017. The result shows that the range of turbidity in the waters around 32,07-190 NTU, nitrate consentration is about 2,325-2,4291 mg/L and phospate consentration around -0,5 – 5 mgC/m2/day. Corelation between turbidity and primary productivity, phitoplankton, nitrate, and phospate respectively shows very weak, moderate, moderate, and weak.Keywords: Turbidity, Primary Productivity, Nutrient, Phytoplankton
