“…Namun hal ini tidak terjadi pada stasiun 5 meskipun terletak di dekat daratan dan membuktikan bahwa kemungkinan sumber masukan dari daratan berpengaruh sangat kecil atau dengan kata lain asupan massa air dari laut termasuk lebih tinggi. Hal ini juga terjadi pada penelitian [9], dimana nilai salinitas pada ujung Teluk Ambon Dalam memiliki salinitas tinggi, meskipun terdapat banyak muara sungai disekitarnya. Pada kedalaman 5 meter terjadi peningkatan nilai salinitas dengan salinitas tertinggi terdapat pada stasiun 5.…”

Penelitian ini dilakukan di Perairan Teluk Prigi pada bulan Mei 2017 di 18 stasiun. Parameter suhu, salinitas dan oksigen terlarut diukur secara in situ dengan menggunakan multi sensor kualitas air AAQ 1183 pada kedalaman 1, 5 dan 10 meter, sedangkan parameter kedalaman diukur menggunakan Echosounder GPS Map 585. Tujuan dari penelitian ini adalah untuk mengetahui distribusi suhu, salinitas dan oksigen terlarut dalam hubungannya dengan kedalaman di Perairan Teluk Prigi. Hasil menunjukkan bahwa kedalaman perairan tidak hanya mempengaruhi distribusi suhu, namun juga distribusi salinitas dan oksigen terlarut. Terdapat perbedaan distribusi parameter perairan yang cukup ekstrem pada 18 stasiun tersebut, terutama pada stasiun 2 dan 5, yang masing-masing terletak pada muara sungai dan Pantai Pasir Putih. Distribusi suhu dan oksigen terlarut mempunyai pola yang sama, namun berbanding terbalik dengan distribusi salinitas. Suhu tertinggi dan terendah ditemukan secara berturut-turut pada stasiun 2 (28,18 o C) dan 5 (26,72 o C). Demikian pula, kadar oksigen terlarut tinggi dan terendah terdapat pada stasiun 2 (8,40 ppm) dan 5 (7,99 ppm). Sebaliknya salinitas tertinggi dan terendah terdapat pada stasiun 5 (34,10 ‰) dan 2 (32,31 ‰). Perbedaan ekstrem pada distribusi suhu, oksigen terlarut, dan salinitas antara stasiun 2 dan 5 terjadi karena adanya pengaruh internal yaitu perbedaan batimetri dan kontur kedalaman pada kedua stasiun tersebut. Stasiun 2 memiliki kedalaman yang sangat dangkal (sekitar 4 meter), sedangkan stasiun 5 memiliki kedalaman yang relatif dalam (sekitar 24 meter). Penelitian ini menyarankan tentang pentingnya informasi batimetri dan distribusi kualitas air sebagai dasar untuk pemanfaatan perikanan dan pembangunan pelabuhan.

“…Menurut Hadikusumah (2008), variasi suhu dipengaruhi oleh pola arus yang dihasilkan oleh pasang surut dan angin. Hal ini serupa dengan hasil penelitian Gemilang et al (2017), dimana suhu perairan di dalam teluk lebih rendah dibandingkan dengan bagian di luar teluk dikarenakan tidak adanya pengaruh angin atau arus. Namun, rata-rata suhu perairan pada kedua lokasi budidaya berada pada kisaran suhu optimal untuk pertumbuhan karang yaitu berkisar antara 25-32 (Dahuri, 2003).…”

Besides the second largest community in the coral reef ecosystem, the attractive shapes and colors of soft corals establish it an export commodity for the marine ornamental aquarium. The transplantation methods in soft coral are limited. Commonly method for soft coral transplantation is attached to the artificial substrate followed by placed at table frame. However, this method is easily covered by algae and costly. One of the alternative methods is vertically hanging that this method commonly applied in hard corals transplantation. This study aimed to examine the average differences of growth rates among different transplanted soft coral species, different location, and the presence of interaction between soft coral species and location towards the difference of growth rates. Moreover, it determined the average survival rates among different transplanted soft coral species at different location. There were three soft coral species, Lobophytum strictum, Sinularia polydactyla and S. asterolobata. They were fragmented at initial size ± 25 cm2, hanging vertically in 1.5 m length, and 0.03 m diameter followed by located inside and outside the Pegametan bay, Sumberkima village, Buleleng Regency. The increased size of each transplanted soft coral species and the number of survivals and environmental parameters were observed every two weeks for 12 weeks. The average in growth rates among species, location, and interaction was analysed using two ways Anova, whereas the survival rates were tested using Log-Rank. Results showed that the average growth rates of transplanted soft coral inside the bay were significantly higher (4.53 cm2) than outside the bay (1.64 cm2). Moreover, the average growth rates of transplanted S. polydactyla were significantly higher than others (5.22 cm2), (respectively; 2.35 cm2 and 1.7 cm2). It was also indicated that different location and species did not differentiate the transplanted soft corals' average growth rate. The survival rates of the transplanted soft corals in different location were not significantly different as well.

“…Dissolved oxygen is one of the important parameters needed by biota for the respiration process and the breakdown of organic substances. The need for dissolved oxygen tends to vary depending on the type, stage and activity [41]. The results of measuring DO at the time of the study were obtained a value of 3 mg / l. The optimal DO value for marine life ranges from 3 -7 mg/l [42].…”

This study aims to find out the activities of local sea cucumber methanol extract (Phyllophorus sp.) as a natural antifouling against macrofouler Nerita sp. This study uses experimental methods laboratory. Laboratory-scale data collection is carried out by observation of biota paste activities fouling on the aquarium (antifouling rate) as well as its regaining rate. This research uses research design complete random design (RAL) with three repetitions. Local sea cucumber methanol extract (Phyllophorus sp.) contains bioactive compounds such as saponins, alkaloids, tannins, steroids and phenolics. Methanol Extract local sea cucumber (Phyllophorus sp.) affects the antifouling rate by reducing the Nerita sp. macrofouler paste rate with increasing concentration. It's the same thing,occurs where the increasing concentration of local sea cucumber methanol extract (Phyllophorus sp.) provides a significant decrease in Nerita sp. macrofouler regaining capability. The results lethal concentration 50 or LC50 obtained a value of 185.18. This means the concentration of the extract sea cucumber (Phyllophorus sp.) is deadly 50% of all biota test at a concentration of 185.18 mg/ml. Based on antifouling rate analysis and regaining rate it is known that the concentration of the most effective that can be used as an antifouling is a concentration of 75 mg/ml. This is because a concentration of 75 mg/ml of local sea cucumber methanol extract (Phyllophorus sp.) can already inhibit paste macrofouler Nerita sp. The concentration of 75 mg/ml also has a large regaining rate of 85%.
