Abstract

This study was aimed to: 1) assess the potential and condition of mangrove ecosystems in Bokor Village to be developed into ecotourism destination, 2) knowing the level of community participations and perceptions, 3) knowing the effort and perceptions of stakeholders concerning to development ecotourism in Bokor Village, and 4) developing a strategy for ecotourism in Bokor Village. The methods used in this study were observation, survey and interviews.The results showed that the mangrove forest in the Bokor Village had good density with very dense with a density of 2955.55 Ind/ha and there were 13 species of mangrove flora. The average value of the category of community participation showed 0.41, thus community participation in the development of ecotourism in the Bokor Village was relatively low. The average value of the category community perceptions was 3.32, it means the level of community perceptions of ecotourism development was classified as supporting category. Furthermore, the results showed that the stakeholders related provide a very strong support for the development of ecotourism in the Bokor Village.Based on the result of SWOT analysis, the development strategy in the Bokor Village was by applying an aggressive strategy (Growth Oriented Strategy) or also known as S-O Strategy (Strength-Opportunities). This consisted of making the general management plan and conservation site plan for the development of ecotourism, building and adding the quality of products/services ecotourism (High Quality), improving access to a wider market and establishing cooperation with universities or research institutions in the field of research and conservation.Keywords: Bokor Village, Ecotourism, Participations, Perceptions

Abstract

The amount of solid waste at station 1 to station more than 2 type of solid waste in the Black Water Strait of each station is almost the same, where the Black Water Strait is dominated by the type of waste plastic and small pieces of wood. In Black Water Strait encountered type of waste that generally consist of plastics, paper, rubber, foam, jute sacks, leaves, and small pieces of wood. From this we can conclude that the solid waste at both stations originate from the same source ie domestic waste. The strong tidal currents provide a direct influence on the amount of solid waste that are found in every point of the study and vice versa if the lower the pressure, the current is the entry-level waste into gear tends to be decreased.Keywords : Comparative Study, Solid Waste, Selat Air Hitam, Meranti Island

Abstract

The research was conducted in February-March 2015 with a goal to determine the relationship between the oil content and the abundance of diatomsin Meral Karimun waters of Riau Islands Province. The survey method was applied in four stations with three sampling strata,i.e. the surface area, the middle and near the bottom. It revealed that the oil content of water ranged from 0.1797 to 0.2063 ppm and diatom abundance were between 44 to 149 cells/l, which contain of 14 species. Apparently, the oil content of seawater was not correlated (p>0.05) with diatom abundance were the coefficient correlation of (r) = 0.318. The regression equation was y = - 468.350x + 184.297 with a coefficient of determination (R2) =0.101 and a correlation coefficient (r) = 0.318. It was suggested that increasing oil content will decrease the abundance of diatoms in the Meral Karimun waters.Key Words:Meral,abundance, diatoms, oil content

Abstract

Indonesia has a local source of raw materials based on natural polymer hydrogel, ie seaweed the number and type of abundant. One of processed seaweed products of high economic value is carrageenan. Synthesis of carrageenan-based hydrogels prepared from local seaweed is still not widely used. Based on the properties that can proved a cooling effect and moisture of water is also restricted by the hydrogel. This research aims to develop the use of carrageenan from seaweed into a hydrogel wound dressings. The current study analysis further the quality of the resulting hydrogel using κ and τ-carrageenan than the optimal concentration of PVA in producing the hydrogel. Well studied conducted with concentration κ and τ -carrageenan (6:4) 3%, and the addition of PVA polymer concentration formulation (7.5%; 10%; 12.5%; 15%), and irradiated using γ-rays at a dose 15 kGy (dose rate of 2.5 kGy / h). Characterization measured include the value of the ratio swelling, gel fraction and tensile strength. The test results hydrogel formulations with increasing concentration of 12.5% PVA ratio swelling 416.58%, 67.39% gel fraction and tensile strenght of 3.48 kg / cm2.Key words: τ-carrageenan, κ-carrageenan, hydrogels, irradiation, hydrogel, a polymer PVA (Polyvinyl Alcohol)

Abstract

ABSTRACTThis research was conducted in coastal waters of Singkep Island held on 28 Januari 2018 – 4 Februari 2018. The study aimed at analyzing Pb, Cr, Cu and Zn concentration in waters column as well as in sediment were taken from two stations with three replicates at each station.. Heavy metals were analyzed by following Hutagalung procedure (1991) and Yap et al., (2003). The results showed that the average content of heavy metals in Singkep water is 0.23 mg/l (Pb), 0.05 mg/l (Cr),  0.09 mg/l (Cu),  and 0.43 mg/l (Zn), the sediment was 3.89 μg/g (Pb), μg/g, 18.53 (Cr), 2.08 μg/g (Cu), 38.67 μg/g (Zn). Simple linear regression analysis indicates negative correlation between Cr, Cu and Zn content in sea water and in sediment with Y =38.51 – 430.4x , r = 0.51 (Cr), Y =37.87 – 378.0x r = 0.88(Cu) ; and Y =45.74 – 16.31x, r = 0.11 ( Zn) and positive correlation between Pb content in sea water and in sediment with Y= -4.2241+ 34.19x, r = 0.71. The concentration of all metals measured in water exceeded the quality standard regulation. However, concentration of metals in sediments were below the ERL and ERM.Key Words : Singkep Island, Heavy Metal, Pollution, Seawater, Sediment

Abstract

ABSTRACT This research was conducted in June 2019 at the Marine Chemistry Laboratory, Department of Marine Sciences, Riau University.The purpose of this study was to determine the ability of ash cockle (Anadara granosa) as biosorbers of zinc (Zn2+).The research was conducted by contacting zinc  and blood clam ash with the variation of concentrationof 14 × 103, 20 × 103 and 26 × 103 ppm with a maximum contact time of 24 hours.Zinc analysis performed by using atomic absorption spectroscopy (AAS). The results showed that the ash shells could be used as adsorption material and variations in concentration could affect the absorption of zinc metal. The optimum absorption occurs at a concentration of 14 × 103 ppm with a 24 hour contact time of 99.67%.Key word: Blood Calm Seashell, Adsorbent, Zinc, Atomic Absorption Spectroscopy

Abstract

ABSTRACTA Study on the abundance of Chaetodontidae, coral cover and  relationship of  abudance with coral cover were conducted from May -          July 2019 in the Lagoi Waters of Bintan Regency of  Riau Islands Province. Abudance of fish observed with Underwater Visual Census (UVC) method while coral cover with Reef Check  method. Apparently the abundance of Chaetodontidae fish ranged from 313.3 - 603.3 ind/ha whereas coral cover ranging from 46 - 74%.Forthat, abudance of coral fish corelated (r = 0.977) with coral cover, suggest that, there is a very strong relationship between live coral cover and Chaetodontidae fish. Key words :Chaetodontidae, Coral Reef, Lagoi Waters

Abstract

Accumulation of Pb and Zn in Blood Shells can be seen that the Shellfish not respond toheavy metal that accumulates in the body at different salinity. Evaluation of the abilityaccumulation Shellfish Blood (Anadara granosa) against Pb fluctuated. While metals Zn showeda fairly high response in the process of accumulation of heavy metals in blood Shells.The concentration of Pb at 20 ppm salinity treatments were the highest found in bothreplicates with a concentration of 0.05 ppm which is equal to 0036 mg / g. While the data waslowest for the first repeat also with a concentration of 0.05 ppm was 0.0027 mg / g. While theconcentration of Zn in the treatment of 20 ppm the highest salinity found in both replicates witha concentration of 2 ppm which is equal to 0.86 mg / g. While the Zn concentration was lowestfor the second replay with 1.5 ppm concentration of 0.38 mg / g.Water quality at each research station there was no difference so far. However, waterquality in the study site contained a water quality to support shellfish life blood. Initialtemperature in this study is the final temperature is 290C and 280C.Keywords: Heavy Metal, Anadara granosa, Salinity
