Abstract

Seagrass ecosystem in Youtefa Bay is very important and useful for the local people’s lives in around the Youtefa Bay. Willingness to Pay (WTP) of the locals toward the seagrass ecosystem is their appreciation for the existing value of seagrass ecosystem. This research explored how much the WTP was given by the local people toward the existences of seagrass ecosystem in Youtefa Bay. The data collection was conducted in March to April 2018 located in three villages around the Youtefa Bay, namely Tobati, Enggros and Nafri Villages as many as 228 respondents. Data analysis of this research was quantitative analysis to find out the mean WTP, aggregate and attribute WTP that influenced WTP value. The result of this research showed that there were 202 respondents were willing to contribute or pay and 26 respondents were not. The obtained WTP value of respondents ranged between IDR 0 to IDR 200,000.00 with mean WTP of respondent was Rp 53,464.91/year meanwhile aggregate WTP was Rp 27,480,964.91/year. Variables which had significant influence toward WTP value were participation at seminaries/trainings regarding coastal ecosystem. Meanwhile gender, age, education level, income, and profession or job variables didn’t make any significant influence toward the given WTP value amount.

Abstract

Kabori Lagoon is a lagoon located in Manokwari Regency, West Papua, where the water quality data is still very limited. Chlorophyll-a is the most important photosynthetic pigment for aquatic plants such as phytoplankton. The purpose of this study was to determine the horizontal distribution of chlorophyll-a based on the spatial data approach in the waters of the Kabori Lagoon. The study was conducted from April to May 2019. The sampling point was determined by purposive sampling at eight points for sampling of chlorophyll-a and water parameters including physics and chemistry (temperature, DO, salinity, brightness and depth). Measurement of physical and chemical parameters is carried out in situ. Chlorophyll-a analysis was carried out at the Laboratory of Water Productivity and Quality, Faculty of Marine and Fisheries Sciences, Hasanuddin University. Spatial data processing used ArcGIS 10.4 and Surfer 16 to create chlorophyll-a distribution maps and bathymetry. The results showed that the chlorophyll-a content in Observation I was in the range of 0.12-2.40 mg/m3 and in Observation II it was in the range of 1.43-10.84 mg/m3. Based on the chlorophyll-a content, the Kabori Lagoon is included in the mesotrophic category. Spatially, the distribution of chlorophyll-a content varies, but tends to be higher in the southern part of the lagoon than in the northern part of the lagoon.

Abstract

As one of the marine areas included in the world's Coral Triangle region, Yos Sudarso Bay have a potential reef fish diversity that needs to be studied. However, there is very little information about reef fish diversity in these waters to date. This study aims to determine the species diversity of reef fish in Yos Sudarso Bay, Jayapura City, Indonesia. The study was conducted in April 2020 at seven sites; six of them located inside the Yos Sudarso Bay and one more located outside the bay. Sampling was carried out using the Underwater Visual Census method (25 m long and 5 m wide). Relative abundance by species, and diversity (H´), evenness (E), and dominance (C) indices were calculated. A total of 1,075 individual reef fish was recorded in seven study sites, representing 122 species and 26 families. Locations showed differences in reef fish abundance (86 to 215 individuals/125 m2), diversity (H´= 2.462 to 3.358), evenness (E = 0.770 to 0.887), and dominance (C = 0.047 to 0.155). This study has provided preliminary information on species diversity, fish abundance, and the ecological index of reef fish in Yos Sudarso Bay, Jayapura City.

Abstract

The zooplankton ecological index which includes diversity, uniformity and dominance is one approach used to determine the condition of the aquatic environment. This study aims to determine the environmental status of the waters based on zooplankton ecological index which includes diversity, uniformity, and dominance in Doreri Bay water, Manokwari. This study was conducted in September 2020 at two 5- and 10-meter stations depth from the water's surface. Water quality measurements and water sampling were carried out at both stations thrice for 1 week. Water sampling to determine individual zooplankton used a 5 L volume Van Dorn. Temperature, salinity, and pH of the waters were measured successively using a rod-type thermometer with a 50 °C scale, a handheld refractometer RHSN-10ATC, and a pH meter of Orion A215 type. The measurement results obtained the temperature, salinity, and pH values ranging from 29.1 – 29.9 °C with an average of 29.5 °C, 30 – 35 ppt with an average of 33.2 ppt, and 7.9 – 8.3 with an average of 8.1, respectively. The diversity, uniformity, and dominance indexes ranged from 1.5 – 2.2, 0.7 – 1.0, and 0.1 – 0.4, respectively. The ecological status of Doreri Bay waters based on the diversity, uniformity, and dominance indexes show that the components of the food chain are still complete, including the producer and consumer groups and reducers. The effect of liquid waste from land activities around the bay has not disturbed the zooplankton.
