Abstract

The mangrove ecosystem is one of the ecosystems in the estuary area that is unique and very sensitive to environmental changes. The large number of aquaculture businesses around Cemare Hamlet, West Lombok Regency have resulted in many mangrove areas being converted into pond cultivation locations. This will have an impact on the life of mangrove ecosystems such as plankton. This study aims to determine the abundance of plankton species around the mangrove area of ??Dusun Cemare, Sheet Selatan Village, West Lombok Regency. The research was conducted in May-October 2019 using a purposive sampling method by determining 7 stations to represent water conditions. Plankton analysis using the Lackey drop microtranscting method. The results showed that the mangrove ecosystem in Dusun Cemare was composed of 4 types, namely: Rhizophora sp., Avicenia sp., Bruguiera sp., And Soneratia sp. The plankton community in mangrove waters is composed of 13 types, while the abundance of plankton species (periphyton) attached to the mangrove roots consists of 6 types. The composition of plankton species which tends to be high indicates that the mangrove waters of Dusun Cemare are still feasible to sustain the survival of the associated biota in it.

Abstract

Plankton has an important role for aquatic ecosystems, especially in the food network in a waters. This study aims to assess the abundance and diversity index of plankton in Sire Beach, North Lombok Regency. The study was conducted in September 2019 using purposive sampling with 9 sample points. The water sample was filtered using plankton net then put into the sample bottle for identification in the laboratory. Shannon-Wienner Index was used for determining diversity of plankton species. The types of plankton found were 12 genera of phytoplankton from the Bacillariophyta group, including: Biddulphia, Coscinodiscus, Cocconeis, Cylindrotheca, Diploneis, Fragilaria, Gyrosigma, Licmophora, Navicula, Nitzschia, Pleurosigma, and Triceratium. The highest abundance of phytoplankton belonged to Coscinodiscus species as many as 1.380 cells/l at station 2.3. The high abundance of Coscinodiscus might be due to a nutrient supply in these waters. Seagrass ecosystem was thought to have an important role in obtaining nutrients for phytoplankton. Diversity index has a value which ranges between 1.117505-1.841236 showing that it is in the medium category. The uniformity index ranges from 0.450718-0.673373 indicating that the distribution of plankton species in each station is even. The dominance index ranges from 0.233508-0.522215. This shows that there is no type of plankton that dominates the waters of Sire Beach. This is due to the abundance of plankton species at each station which is fairly evenly distributed.

Abstract

Economic valuation is an important instrument in making policies for managing coral reef resources effectively and efficiently and is able to distribute the value of benefits and costs in developing conservation areas. This study aims to determine the economic valuation of coral reef resources in TWP Gita Nada Sekotong Lombok Barat Regency. The research used the survey method with a sample size of 45 respondents determined by purposive random sampling based on the status of the respondent. Data analysis uses the Total Economic Value (TEV) approach by aggregating the value of direct benefits, indirect benefit values, value of selected benefits, value of existence benefits, and value of inheritance benefits. The results showed that the TEV of coral reef in TWP Gita Nada was Rp. 147,976,915,107.98/year or IDR 54,778,806.30/ha/year. The value of indirect benefits contributed IDR 113,523,601,904.00 per year (76.7% of the total economic value of coral reefs), while the direct benefit contributes Rp. 34,453,313,203.98 per year (23.3% of the total economic value of coral reefs).

Abstract

Protection and sustainable data collection are very important in order to protect the coral reef ecosystem. This research was conducted to monitor and determine the condition of coral reefs in the eastern part of Gili Gede Island, which is administratively located in Sekotong Sub-District, West Lombok Regency, NTB. The method used is Line Intercept Transect (LIT). Furthermore, the starting point of the transect stretch is recorded using GPS coordinates and the depth gauge is used to estimate the depth of the water. The results showed that the status of coral reefs tended to be badly damaged with the mean value of all stations (21.92%). Fishery activities and pressure from the land are thought to be several factors that tend to affect the poor coastal ecosystem

Abstract

The whitespotted guitarfish (Rhyncobatus Springeri) resource is an important commodity and has high economic value. This study aims to determine the growth pattern of whitespotted guitarfish landed in the PPI Sungai Kakap. This research was conducted at the PPI Sungai Kakap, Sungai Kakap District, Kubu Raya Regency, West Kalimantan Province in July and August 2019. Data was collected by observation, surveys, and interviews. Data analysis of sex ratios, length, and weight was carried out on samples of whitespotted guitarfish. The results of the analysis of the sex ratio of male and female whitespotted guitarfish were 1.00:1.44, this shows that the number of male fish caught is relatively equal to the number of female fish caught. The results of the analysis of the length and weight relationship of whitespotted guitarfish, the a value is 20.643 and the b value is 0.6770. That value represents a negative allometric growth pattern for male and female fish. The negative allometrics explain that the length growth is faster than the weight growth. Generally, the increase of the length and weight is equal, but the whitespotted guitarfish has length growth faster than weight growth

Abstract

The survival of coral larvae as early phase of coral life is very important for their viability in environmen. This research aims to determine the survival of Acropora sp planula at different densities intensive nursery, and also to khow the critical survival time of them.. This research method was used experiment in density of larvae were held in control laboratory. The planula were rearing ini small container 200 ml of water while the lavae density were used namely 0.5; 1.0, 1.5, 2.0 larvae / ml. The results indicated that survival rate for larvae of different densities (0.5 larvae/ml; 1.0 larvae/ml; 1.5 larvae/ml; 2.0 larvae/m) did not show any significant difference (P>0.05). the highest survival rate of planula larvae was in the treatment with a density of 1.5 larvae/ml and the lowest from a density of 2.0 larvae/ml, and the most larval mortality was in the first 12 hours of rearing, due to the degree of adaptation of larvae to the rearing water medium in all treatment units, then death coral larvae decreased exponentially. This research will be very useful for efforts to restore coral reefs sexually, so as to reduce the impact of exploitation of coral seedlings which are often taken for asexual coral reef restoration as is often done throughout the world's coral reefs.

Abstract

Research related to aerosols in Indonesia is still very minimal compared to sea surface temperature parameters and other oceanographic parameters. This study is a preliminary study that aims to determine the variation in aerosol distribution and its influence by variations in sea surface temperatures in the areas crossed by Arlindo, especially the savu sea. Savu sea surrounded by Flores islands (Sumba Regency, Kupang Regency, and Manggarai Regency) has a variation of SPL from 22 - 30 °C, where in the wetar strait, ombai strait, and sumba strait in the northwest part of sawu often occur low temperatures. While the value of aerosol spread is ranging from 0 - 0.3. Thus, a numerical model is needed that can help in analyzing the results that currently exist.

Abstract

The shape of marine protected areas (MPAs) aimed for fisheries goals should be small enough to allow for spillover of adult fished species as well as larval and juvenile fished species. Such consideration was applied during the establishment of Liang-Ngali Island MPA in West Nusa Tenggara (WNT), Indonesia, which was mainly developed to support fisheries activities around it. In WNT, biologically diverse coastal and marine ecosystems have been utilized by local residents to support their livelihoods, mainly through fisheries and tourism activities. Aside from being a home for unique habitat such as mangrove forest, seagrass beds, and coral reef, Liang and Ngali Island also shows indication of spawning aggregation sites for reef fishes such as groupers and snappers. In 2016, the government of WNT Province designated both islands as marine protected areas under the category of marine recreational park. Following the Governor Decree, a management and zonation plan of Liang-Ngali MPA was then developed by engaging stakeholders from multiple institutions. In the framework of ecosystem approach to fisheries management, the existence of MPA provides strong instrument to support the sustainability of fish resources as well as maintaining continuous livelihood for surrounding coastal communities.

Abstract

Halophilic bacteria are bacteria that can survive in environments with high salt levels, one of which is in salt ponds. Therefore, it is necessary to research to determine the morphology of halophilic bacteria for further use in the identification of bacterial species. This study aimed to determine the colony morphology and types of gram halophilic bacteria. Isolation of halophilic bacteria was carried out using the scatter method. Bacterial purification was carried out by streak method, then morphology identification and bacterial staining were carried out to determine the cell shape and gram of bacteria. The isolation results obtained 4 isolates from raw water (B.AB.1) and reservoir (B.B.1, B.B.2, and B.B.3). The results of the identification of the colony morphology of each bacterial isolate had different colors, shapes, colony edges, elevations, and surfaces. The results of the gram staining test showed that 2 isolates (B.B.1 and B.B.2) were gram-positive and 2 bacterial isolates (B.AB.1 and B.B.3) were gram-negative. The isolates of B.AB.1, B.B.2 and B.B.3 were in the form of bacilli, while the isolates of B.B1 were in the form of cocci.

Abstract

Seagrass is a coastal ecosystem that has important role as a feeding ground, a spawning ground and a nursery ground for various marine biota. This study aims to examine the biodiversity of seagrass at Gili Air, North Lombok Regency, West Nusa Tenggara. This study was conducted to observe the cover percentage of seagrass, it's composition, the number of seagrass stands, canopy's height, frequency of seagrass presence, and index of importance of seagrass. Seagrass data was collected using a 50cm x 50cm quadrant transect, with a total area of 100 m2, referring to the monitoring standards set by SeagrassNet. Water quality analysis was carried out at the Bioecology Laboratory of the Aquaculture Study Program, University of Mataram, and at the Laboratory of the Marine Aquaculture Center (BPBL) of Sekotong, West Lombok. The results showed that the seagrass communities in Gili Air waters were composed of 5 (five) species: Halophila ovalis, Thalassia hemperichii, Cymodocea rotundata, Halodulea pinifolia, and Halodule uninervis, with the percentage of coverage ranging from 26.88-39.17%, and the average coverage by 31.53%. Thalassia hemperichii is the species that has the highest contribution to the seagrass community at Gili Air.
