Abstract

The appearance of whale sharks in several waters in Indonesia has now encouraged the development of tourism activities based on whale sharks. One area that has become a tourist destination for whale sharks both locally and abroad is Botubarani Waters, Gorontalo. Some experts reveal that the presence of whale sharks is influenced by environmental factors, such as salinity, temperature and pH. This study was aimed to measure the value of water quality (temperature, salinity and pH) in the Botubarani whale shark tourist area, Gorontalo so as to create a balance between whale shark tourism and the preservation of the tourist attraction itself. This research was conducted in Botubarani waters, from 8 March to 8 April 2020. The data collection of temperature, salinity and pH was carried out for 30 days. The data collection point is the area where whale sharks were found to surface. Data were collected on temperature, salinity and pH, respectively, using alcohol thermometer, seawater hydrometer and pH test paper. The results showed that the temperature values in Botubarani waters ranged from 24-30.3 ºC, salinity ranged from 33-36 ppt and pH 7. The conditions of Botubarani waters (temperature, salinity and pH) were still in the optimal category for both whale sharks and marine tourism

Abstract

Mangrove forest is a type of forest that grows in tidal areas, especially on protected beaches, lagoons, and river mouths whose vegetation communities can tolerate high salinity). This research began to be carried out from March to June located in Tampara village, South Kaledupa District, Wakatobi Regency, Southeast Sulawesi Province which aims to determine mangrove species, density, closure, and Important Value Index (IVI). The method used is line transect. The observations found 4 types of mangroves in the transect, namely Rhizophora stylosa, Bruguiera gymnorrhiza, Rhizophora mucronata, and Rhizophora apiculata. The density of trees and seedlings has a good density with an average of very dense criteria, while the mangrove sapling category has a damaged density and all stations have a rare density. The highest closure was Bruguiera gymnorrhiza 96.49% (station 4), the lowest was Rhizophora apiculata 2.75% (station 1). The highest overall IVI of mangroves was 200% of Rhizophora stylosa and Rhizophora mucronata (stations 2,3,4 and 7) and the lowest IVI was 39% of Rhizophora mucronata at station 5 seedling level.

Abstract

The aims of this study was to determine the distribution patterns and diversity of seagrass in Pallette and Tangkulara waters. This research was conducted for two months, from August to September 2019. Data collection was carried out at two points with three replications each. Seagrass data retrieval uses the line and quadrant transect method. The results showed that there were 5 species of seagrass found in the Pallette and Tangkulara Waters, namely Enhalus acoroides, Thalassia hemprichii, Halodule uninervis, Cymodocea rotundata, and Halophila sp. The diversity of seagrass species in the Pallette and Tangkulara Waters was in the low category. Distribution patterns of all species of seagrass Thalassia hemprichii Halodule uninervis, Cymodocea rotundata, Halophila sp. has a grouped distribution pattern value while for Enhalus acoroides the distribution pattern is equal.

Abstract

Macrobenthos are aquatic organisms that live on the bottom of the waters with relatively slow movements which are strongly influenced by the basic substrate and water quality. This data collection aims to identify macrobenthos, calculate the abundance, diversity and dominance as well as the composition of macrobenthic species and to determine the quality of the waters on Kelapa Dua Island. The method used in this activity uses a transect line technique that is pulled along 50 meters in a perpendicular direction from the coast to the sea, on each transect a frame measuring 1x1 meter is placed. Observations were made at 3 stations, where each station was repeated 3 times. Observations showed that there were two classes of macrobenthos, namely gastropods and bivalves. From the results of data collection obtained two classes of macrobenthos, namely gastropods and bivalves. The abundance value (Di) is 1685 Ind/m², the diversity value (H') is 23.56, and the dominance value (C) is 0.51, and the species composition value (9.09%). Water quality measurements obtained from the data collection include, water temperature (C°) in the range of 29-33, depth (cm) 20-42, current velocity (m/s) 0.06-0.08, salinity (ppt ) 20-27 and pH 6, and the water substrate contained coarse sand, fine sand, rubble.

Abstract

The purpose of this study was to identify the type of algae, calculate the composition, density, diversity index, similarity index, and dominance index, and measure water quality parameters in the waters of the Banda Sea marine tourism park in central Maluku Regency. The method used in this study is a line transect method and a quadrant frame measuring 1m x 1m. There are 3 stations used with 5 replications each. The results showed that there were three divisions of algae, namely Chlorophyta, Phaeophyta, and Rhodophyta, with details of the species obtained were Amphiroa fragilissima, Boodlea composita, Boergesenia forbesii, Cladophora, Chaetomorpha crassa., Dictyota dichotoma, Gracilaria edulispuntia, Halimeda macrophyopuntia. tuna, Padina australis, Ulva compressa, Ulva reticullata, and Valonia ventricosa. The Chorophyta division of 66% obtained the highest species composition value, the highest density was obtained by the Amphiroa fragilissima species of 0.205. In addition, the ecological index such as (1) the diversity index was in the medium category with a value range of 1.35-1.97, (2) the similarity index was included in the high category with a value range of 0.72-0.86 which indicates that the ecosystem is in a stable condition and the dominance index of the three stations shows a value close to one, namely 0.87-1 which indicates that there is a tendency for one species to dominate. The measurements of water quality parameters such as temperature, salinity, and currents show that they are optimal for algae growth.

Abstract

Padang lamun merupakan ekosistem perairan dangkal yang kompleks, memiliki produktivitas hayati yang tinggi. Oleh karena itu padang lamun merupakan sumberdaya laut yang penting baik secara ekologis maupun secara ekonomi. Tujuan dilakukannya penelitian ini adalah untuk mengetahui komposisi jenis lamun yang ada di Perairan Tanjung Pallette dan Tangkulara. Penelitian ini dilakukan selama dua bulan, mulai bulan Agustus sampai September 2019. Pengambilan data lamun dilakukan di dua titik dengan masing-masing tiga kali ulangan. Pengambilan data lamun menggunakan metode transek garis dan kuadran. Parameter kualitas yang diambil adalah suhu, arus, kecerahan, pH, dan salinitas. Hasil penelitian menujukkan bahwa terdapat 5 spesies lamun yang ditemukan di Perairan Pallette dan Tangkulara, yaitu Enhalus acoroides, Thalassia hemprichii, Halodule uninervis, Cymodocea rotundata, dan Halophila sp.Penutupan jenis lamun tertinggi pada Perairan Pallette adalah Thalassia hemprichii sebesar 22,67% sedangkan penutupan lamun tertinggi pada Perairan Tangkulara adalah Cymodocea rotundata sebesar 25,6 %. Data kualitas air yang diambil menunjukkan masih optimal untuk lamun bertumbuh.

Abstract

Nara Bay Beach has enormous marine resource potential with high biodiversity. One of the marine resources owned by Nara Bay Beach is seagrass beds. The purpose of this study was to calculate the composition, species density and cover of seagrass and to measure water quality parameters at Nara Bay Beach. The method used in collecting seagrass data at the location is the quadrant transect. The number of stations used is 3 stations. The results showed that Cymodocea rotundata had the highest species composition value of 73.48% (ST.3), the highest density was obtained by Syringodium isoetifolium of 161.8 (ST.3), the highest seagrass cover was obtained at ST. 3 and for water quality parameters (temperature, salinity, currents and pH) are still within optimum limits for seagrass growing.
