Abstract

The Indonesian archipelago is a region with high marine diversity, especially in the coral reef ecosystem. Coral reefs have ecological functions such as habitat and foraging. However, coral reefs facing various threats including land pollution, fishing effects, climate change, and coral reef depletion caused by ocean acidity. The condition of coral reefs in Pemuteran waters now is much different from a few years ago. Many organisms symbiosis in living and dead corals, especially crabs. Water depth can affect the abundance of crabs. This study was to determine the level of crab diversity on dead corals (Acropora sp. And Pocillopora sp.) Based on differences in depth. The water depth was divided into 5 and 20 meters. Each depth is taken by three Acropora sp. and three Pocillopora sp. The types of crabs that obtained consist of the family Cheiragonidae, Eriphiidae, Leucosiidae, Majidae, Pilumnidae, Pinnotheridae, Porcellanidae, Xanthidae, Portunidae, and Goneplaciade. Highest composition of crab species in Acropora sp. depth of 5 meters 60% (Xanthidae) and depth of 20 meters 37% (Portunidae and Pilumnidae). Highest composition of crab species in Pocillopora sp. A depth of 5 meters 34% (Xanthidae) and depth of 20 meters by 37% (Pilumnidae). The highest density of Acropora sp. is 37.03 ind/cm2 and Pocillopora sp. is 229.63 ind / cm2. The diversity index analysis of crabs at 2 depths category is moderate, which means that the balance in the ecosystem is unstable, where there are some of species with low and high tolerance levels if there is a change in pressure from the environment.

Abstract

Seagrass is the only flowering plant which has a true roots, leaves, and stems, an angiosperm plant that adapted to live entirely in the ocean. Seagrass produces several compounds which produced through secondary metabolism, one of the secondary metabolism is the phytochemicals. Seagrass ecosystem in Tanjung Benoa was discovered along Samuh Beach, where 9 kinds of seagrass species were found around the seagrass ecosystem in Tanjung Benoa. Samuh Beach has a tranquil water conditions and sandy substrate. The activities of marine tourism and hotel waste disposal in Tanjung Benoa waters cause major ecological pressure and physical pressure for the seagrass ecosystem. This study aims to determine the content of phytochemicals in the leaves and roots of seagrass. Screening method was used to determine the content of bioactive alkaloids, flavonoids, saponins, steroids, and tannin compounds. Each of these compounds has an important role in the seagrass. The existence of chemical compounds of the flavonoid, alkaloid and steroid groups in the roots and leaves of Cymodocea rotundata seagrass, Enhalus acoroides, Thalassia hemprichi, Halophila ovalis, Halophila minor, Halodule uninervis and Sryngodium isoetifolium in this study indicate that the seven species of seagrass has potential as a natural chemical antifouling, antifungal, and antibacterial.Then the seagrass will be protected from the danger of predators or epiphanies that interfere with the growth of seagrass and the ecosystems on Samuh Beach will remain intact.

Abstract

The existence of coral reef fish is closely related to the availability of coral reef resource as a habitat. Coral reef fish is a biota that has a fascination with a variety of color patterns and fascinating. Differences in coral cover conditions will affect the abundance of coral reef fish, especially those with strong linkages to living corals. This research was conducted in June - August 2017 by using line intercept transect (LIT) method for coral cover percentage and visual census method for biodiversity and biomass of coral reef fish with 3 research stations in Manggis waters, Karangasem. From the research results, it shows that the diversity index ranged between 2.54 - 2.70 which means the diversity of coral reef fish in the medium category and the stability of the community is in the medium. Furthermore, total biomass of coral reef fish ranged between 186,17 - 1692,08 kg / ha. The results stated that the percentage of live coral cover in Manggis waters ranged from 3.83% to 12.44% which means that live coral cover is categorized as bad. A very strong positive correlation between living coral conditions and coral reef fish biomass was 92.42%. Meanwhile, the relationship between living coral conditions and the diversity of coral reef fish had a strong positive correlation of 65.4%. The diversity of coral reef fish in waters is not only caused by live coral cover; however, it is caused by coral reef ecosystems that are associated in the bottom of the waters.

Abstract

The population of olive ridley has declined in Indonesia, so that efforts are needed to preserve this turtle population through conservation. In conservation of olive ridley, the selection of the precise feed will affect for a good growth. Feed that has high protein content one of them is dried rebon shrimp and tongkol fish. The utilization of feed from dried rebon shrimp and tongkol fish, especially mix feed of these two feeds for olive ridley baby is still very limited information. This research aims to determine the comparison growth rate of olive ridley with a feeding of tongkol fish, dried rebon shrimp and mixed feed also to know the percentage of feed efficiency. The research was conducted for six weeks at the conservation center TCEC Serangan, Bali. The design method used was Completely Randomized Design (CDR) with one control and three treatments, each treatment getting five repetitions. ANOVA analysis was used to analyze the mean differences between groups and the calculation of feed efficiency was performed to see the percentage of feed that was most efficient in the body of the hatch. The results showed different feeds gave different growth rates. The high protein on mixed feeds has produced the highest growth rates compared with dried rebon shrimp and tongkol fish feed. Similarly, the percentage efficiency of mixed feed is more efficient compared with dried rebon shrimp and tongkol fish feed.

Abstract

Mangrove menjadi salah satu ekosistem lahan basah yang berperan penting dalam menyerap karbon. Namun, secara alami ekosistem mangrove juga mampu mengemisikan gas rumah kaca kedalam atmosfer. Metana merupakan salah satu gas rumah kaca yang berdampak signifikan terhadap perubahan iklim. Penelitian tentang siklus metana telah dilakukan di ekosistem mangrove TAHURA Ngurah Rai Bali. Penelitian ini bertujuan untuk mengukur konsentrasi gas metana pada tiga zona ekosistem mangrove. Metode chamber tertutup digunakan dalam pengambilan sampel gas yang kemudian dianalisis dalam gas kromatografi dengan sensor flame ionization detector (FID). Karakter ekologi mangrove yang terdiri dari parameter struktur komunitas mangrove dan lingkungan diukur dari setiap plot kuadrat pengambilan sampel gas. Hasil penelitian menunjukkan konsentrasi gas metana tertinggi ditemukan pada zona darat dengan rata-rata 3,698 ± 0,986 mg. L-1. Walaupun demikian, konsentrasi gas metana pada dua zona lainnya tidak menunjukkan perbedaan yang signifikan dengan zona darat. Variabilitas konsentrasi gas metana tidak berbeda signifikan dengan kondisi struktur komunitas mangrove yang berbeda antar zona. Penelitian ini hanya menemukan variasi nilai potensial redoks (ORP) yang berhubungan signifikan dengan konsentrasi gas metana. Hasil penelitian mengindikasikan bahwa karakter ekologi mangrove yang cukup seragam di kawasan sehingga, tidak menimbulkan perbedaan yang signifikan pada konsentrasi gas metana antar zona. Namun, parameter kondisi substrat lainnya perlu dilibatkan dalam penelitian berikutnya.AbstractMangrove is one of the wetland ecosystems that play an important role in carbon sequestration and storage. However, the ecosystem also emits greenhouse gas into the atmosphere naturally. Methane has been considered as a significant effect on global warming. A preliminary study in a part of the carbon cycle was conducted on the mangrove ecosystem in Ngurah Rai Forest Park Bali. This study was aimed to determine methane gas concentration in three different mangrove zones. Gas samples were collected by closed chamber method and they were analyzed using gas chromatography embedded with the flame ionization detector (FID) sensor. Mangrove ecological parameters i.e. community structure and environmental condition were determined on each quadratic plot where gas samples were collected. The result showed that the highest methane concentration was found in the landward zone at 3,698 ± 0,986 mg. L-1. Even though, the methane concentration of the other zones had not significantly different from the landward zone. In addition, the mangrove community structure among the three zones was not different significantly. The oxidation-reduction potential was the only factor that had a significant correlation with methane concentration. Those results indicated that mangrove ecological conditions among zones were similar to each other,  hence the variation of methane concentration was not significant. Nevertheless, substrate abiotic characters need to be involved in greenhouse gas studies in the future.
