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

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

Salah satu kawasan konservasi perairan yang telah dicadangkan oleh pemerintah dalam hal ini Dinas Kelautan Provinsi Sulawesi Selatan yang telah dimuat dalam Dokumen Rencana Zonasi Wilayah Pesisir dan Pulau-Pulau Kecil (RZWP-3-K) tahun 2019 adalah KKPD TanaLili dengan luas 1.512,34 Ha. Setelah dicadangkan sejak tahun 2019 hingga sekarang belum memiliki rencana pengelolaan dan zonasi. Penelitian ini dilakukan dengan tujuan: (1) Memetakan sebaran ekosistem wilayar pesisir kawasan konservasi perairan Tana Lili, (2)Memetakan zonasi kawasan konservasi perairan daerah Tana Lili. Penelitian ini dilaksanakan pada Maret-Juni 2021.Pembuatan peta zonasi menggunakan software Marxan. Data citra satelit yang sudah diunduh kemudian dilakukan diproses melalui beberapa tahap, yaitu koreksi radiometerik, koreksi geometric, masking & cropping, komposit dan penajaman citra dan ground truth.  Hasil penelitianmenunjukkan bahwa sebaran ekosistem mangrove seluas 34,21 Ha, ekosistem padang lamun seluas 35,95 Ha dan ekosistem terumbu karang seluas 140,39 Ha. Peta zonasi menunjukan Zona Inti seluas 71,34 Ha, Zona Pemanfaatan Terbatas yang terdiri atas subzona Perikanan Tangkap dengan luas sekitar 979,83 Ha, Subzona Pariwisata Budidaya dengan luas 316,43 Ha, Subzona Wisata Bahari dengan luas sekitar 11,04 Ha

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.
