Miangas Island is one of the outer islands of Indonesia. Determining policies for optimal and sustainable spatial use of coastal areas on Miangas Island requires a deep understanding of the people who live there. Observation survey and interview methods were used to collect primary data. The analysis used is the Analytical Hierarchy Process (AHP) to formulate solutions to land use conflicts in coastal and marine areas. The results of the analysis of conflict resolution on the use of coastal space using AHP show that the criteria that have a large influence on the purpose of conflict resolution analysis are land availability and suitability, and the first priority for alternative spatial development for the coastal area of Talaud Islands Regency is the development of fishery areas.

Sea urchins were ecologically and economically important biota, but scientific information on sea urchins is still very minimal and there is no ongoing monitoring. The purpose of this study was to determine the density, abundance, community structure, and distribution patterns of sea urchins in the intertidal zone of Karanrang Island, Pangkep Regency. The research in June-July 2022 was carried out at high and low tide using three transects measuring 1 x 1 m consisting of four plots measuring 50 x 50 cm. Determination of stations based on information from local residents to get observation stations based on tidal conditions. The results showed that three species of sea urchins from two families were found, namely Diadema setosum, Echinothrix calamaris, and Tripneustes gratilla. The species of D. setosum was found to be very abundant (97.3-97.6%) and tended to be more abundant during high tide than during low tide. The index of diversity and uniformity of porcupine species is low (H' = 0.130-0.142 and E = 0.118-0.129). The species dominance index was in the range of 0.946-0.953 indicating high dominance of D. setosum. Spatially, D. setosum had a uniform distribution pattern, whereas E. calamaris and T. gratilla were distributed in clusters. Further spatial and temporal research is needed to comprehensively determinant the conditions of the sea urchin population on Karanrang Island, Pangkep Regency.

Mangrove ecosystems consist of tropical plants that have adapted to the salinity, tidal fluctuations, and loose soil condition. Identification of mangrove ecosystems can be carried out by direct survey methods or by utilizing remote sensing technology. This study aims to map the area, percent cover, and density of mangroves in Makassar City using Sentinel 2A Imagery. The method used is the NDVI transformation, followed by Unsupervised-ISODATA classification, ground check with the 10 x 10-meter plotting method, and hemispherical photography. The results showed that the existence of mangroves in Makassar City was still found in the Tallo and Biringkanaya districts, with 68.81 ha of mangrove ecosystem cover area in the range of 84.36 - 91.89% (dense category). Likewise, the vegetation index based on NDVI analysis ranged from 0.73 - 0.81 (dense category), and the species density was in the range of 2700 - 6400 trees/Ha (dense category). Sentinel-2A imagery transformed with NDVI can be used to track mangrove areas and their density. The wide distribution of mangrove ecosystems in Makassar is relatively small but has good conditions.

Macrozoobenthos are bottom animals that play an important role in the productivity of waters in seagrass beds. This study aims to determine the species composition, density of macrozoobenthos, community structure of macrozoobenthos and the relationship between seagrass density and density of macrozoobenthos. The research method used is purposive sampling method, this method is taken based on certain reasons and criteria. This research was conducted in June-July 2022 on Barrang Lompo Island. Sangkarrang District, Makassar City. There were 26 species found consisting of 4 classes namely Bivalvia, Gastropods, Chepalopods and Crustacea with a total of 283 ind and dominated by the Gastropod class, both from the number of species and individual density. Macrozoobenthos community structure on Barrang Lompo Island at station I and II with a moderate diversity index (H'), moderate uniformity index (E') and low dominance index (D). The types of seagrass found at stations I and II were Enhalus acoroides, Thalassia hemprichii, and Cymodocea rotundata. The regression results of the relationship between seagrass density and macrozoobenthos density on Barrang Lompo Island show a weak relationship, which means that seagrass density has no relationship with macrozoobenthos density but macrozoobenthos density is influenced by physical and chemical factors of the waters and the type of sandy substrate.

The waters of the Beladeng River Muara is one of the areas in the Dompak Tanjungpinang Sub-District which has quite large potential for mangrove ecosystems. To maintain the condition of the mangrove ecosystem, it is necessary to know the structure of the mangrove community itself. The purpose of this study was to determine the types of mangroves and the structure of the mangrove community which includes the level of species density, species frequency, species closure, importance value index and mangrove canopy cover in the waters of the Beladeng River estuary, Dompak Tanjungpinang Village. This research was conducted in April-December 2022 using the Purposive Sampling method with 3 stations. In observing the mangrove ecosystem using the Transect Line Plot method measuring 10x10 m2. Based on the results of the study, there were 3 types of mangroves found, namely Rhizophora apiculata, Xylocarpus granatum, and Brugueira gymnorhiza. Meanwhile, the mangrove community structure obtained the highest density at station 3 with a value of 4733.34 ind/ha. At station 1, the types of Rhizophora apiculata and Xylocarpus granatum received the same frequency values, and the highest IVI was achieved by Xylocarpus granatum. At station 2 the highest species frequency values were found in 2 species, namely Xylocarpus granatum and Rhizophora apiculata, and the highest IVI was Rhizhopora apiculata. For station 3, the 3 types of mangroves got the same type frequency value, and the highest IVI was achieved by Rhizophora apiculata. Meanwhile, the highest percentage of mangrove canopy cover was found at station 1 with good and very dense categories.

Bonylip barb (Osteochilus vittatus) is one of Indonesia's local fish which is starting to bloom in cultivation. One of the important needs in the development of fish farming is feed, to increase feed efficiency by providing probiotics which play a role in increasing growth, survival rates, digestibility, feed efficiency, the immune system and the composition of beneficial bacteria in the digestive tract of fish. This study aims to compare the concentration of different probiotics in commercial feed on the growth and survival of barley nilem (Osteochilus vittatus). The research was conducted at Pandaan Aquaculture Installation (IPB), Pasuruan Regency, East Java. Experimental study using a completely randomized design (CRD) with four treatments and three replications. Statistical analysis to compare growth performance (length and weight) and survival of nilem fish used analysis of variance (ANOVA) test. The results showed that there were differences in the growth of weight, length, and survival of barley nilem (Osteochilus vittatus) on commercial feed with different concentrations of probiotics. Where there is a tendency that the higher the concentration of probiotics in commercial feed, the higher the growth in length and weight and survival of nilem fish (O. vittatus).
