Coastal ecosystems are dynamic ecosystems that have a rich diversity of habitats on land and in the ocean, as well interacting between one habitat with another. The purpose of this study is to identify the ecological parameters of the coastalecosystemamarineecotourism area and determine the suitability class of the KokoyaIsland coast as amarineecotourism area for the coastal tourism category. This research was conducted in January to February 2019. Data collection using primary data with survey methods and direct measurements in the field. The analysis is used to analyze the suitability of the beach ecosystem class on KokoyaIsland by using the area suitability matrix for the recreation category of beach tourism. The results showed that at 7 stations in the study location had a Travel Conformance Index in the category of Very Appropriate (S1) and Appropriate (S2). The IKW of each station can be presented; Station 1 IKW. 92.31% (S1), Station 2 IKW. 89.74% (S1), Station 3 IKW. 89.74% (S1), Station 4 IKW. 97.44% (S1), Station 5 IKW. 78.21% (S2), Station 6 IKW. 90.38% (S1), and Station 7 IKW. 97.44% (S1).
The area of Liwutongkidi island in the Districtof Buton, Province South East Sulawesi, has a varied coastal and marine resource potentials, such as coral reef ecosystem. The objectives of this research was (a) to identify the potential for coral reef ecosystem in the islandof Liwutongkidi area (b) to analyze the suitability and carrying capacity of coral reef for tourism development (c) to estimate the economic value of the tourism. The coral reef ecosystem can be used to study its suitability for marine tourism objects of diving and snorkeling. Collected data were life form of coral reef, coral fish, current speed, water transparency and coral reef depth. The formula used to determine tourism suitability is suitability matrix of diving and snorkeling, and Scenic Beauty Estimation (SBE) to judge the quality of landscape. Line intercept transept method during survey showed that Islandof Liwutongkidi area had a condition of coral reef in the category of “good” with the average coral coverage is 52.03%. However the economic value was very low calculated the travel cost method analysis.
Coastal and marine tourism has become a big business which is a significant part of the growing global tourist industry. Marine tourism activity, namely diving tourism is very important and is international tourism market. Increased activity of diving tourism if not managed in a sustainable manner will cause damage to coral reefs as its object. The main goals of this research are: 1) Identify the biophysical conditions of coral reef for marine tourism, 2). To analyze the coral reef’s carrying capacity for diving tourism development, 3) Formulating the strategic direction of diving tourism development based on the biophysical carrying capacity of coral reef. The survey was conducted at 5 sites with each site into 3 and 10 m depth, percentage of live coral cover using the Line Intercept Transect (LIT) method, shows that life cover coral is ranging from 22.73% to 45.72% of the sites. The composition of reef fishes community using the Underwater Visual Census (UVC) is 18 families with 85 species of reef fishes. All sites are suitable to be developed for diving tourism areas. The Carrying Capacity of area for diving tourism is ranging from 10 until 17 people per/day. From 30 images with Scenic Beauty Estimation (SBE) values are 17 types of high category, while 12 species are medium category and 1 species is low category . Residents and visitors alike have a positive view for the marine tourism development. They would like to see the conservation of the coral reef and economic benefits.
Rehabilitating and reconstructing the ravaged areas are not straightforward and short- time efforts, on the other hand, they call for strong commitment of multi sides, well- thought and precise planning and designing, and definitely a great deal of investment. The works ask for long period and, during implementation, both studies and assess- ments of multi dimensional aspects incorporating social, economic, cultural, environ- mental, ecological, etc. that altogether integrated in planning and implementation. One amongst the marine and fishery rehabilitation and reconstruction projects is the Green Coast Project. It is organized as joint project with WWF, Wetlands Internation- al, both ENDs and IUCN, while financial sponsorship run by n(o)vib. The project aims at protecting the uniqueness ofcoastalecosystem and improving income of the coastal villagers. The main target is to recover coastal ecological functions and to provide sus- tainable income sources for the local villagers struck by the tragedy. The project’s out- puts are to get coastal areas rehabilitated; new or renewed income sources accessible; community’s means of livelihood (mainly fishery and ecotourism) re-established, re- newable resources through coastal communities’ participative focusing on planning and women’s roles become useable.
to the ecological balance for the sustainability. It is expected that the potency of the seagrass ecosystem can be appropriately maintained both for conservation and ecotourism areas. The management also should pay attention to the potential threat to this ecosystem. Mainly, the current environmental condition brings the seagrass ecosystem to be prone to damage. The seagrass is facing a crisis due to various reasons including pressures from human activities in the coastal zone, the increasing of the frequency and intensity of natural disasters such as hurricanes, which may be indirectly associated with human activities (i.e. global warming) (Orth et al., 2006). 4.

The Based on results and discussion of this research, it can be concluded that the physical chemical environmental factors (temperature, salinity, and dissolved oxygen) in the coastal waters of Marsegu Island experienced fluctuations, while the pH of seawater did not experience a fluctuation in the measurement which was carried out in the morning, afternoon and evening. The physical chemical environmental factors had an effect on the structure of macrozoobenthos community in waters. The macrozoobenthos found in the coastal waters of Marsegu Island consisted of 2 Phylum, namely Mollusk and Echinodermata, that is, gastropods with 17 species, bivalves with 5 species, and echinoderms with 18 species. Based on the number of the Macrozoobenthos found, the results of the diversity index calculation of macrozoobenthos in the three research stations showed that the highest value was at station 1 with 3.56, followed by Station 2 with 3.52 and the lowest was station 3 with 2.07. In addition, Nerita sp species was the main constituent component of the macrozoobenthos community in the coastal waters of Marsegu Island. This can be seen from the density value, occurrence frequency, and importance value index of Nerita sp which was high on the three research stations, while Culcita novagaeguinea species had the smallest contribution on the structure of macrozoobenthos community in the coastal waters of Marsegu Island.

The aim of the research is to analyze the economic value of Weh IslandMarine Tourism Park (TWA Laut Pulau Weh) in Sabang City and to formulate and assign the policy of its management. The development of TWA Laut Pulau Weh faces some aspects such as economic, social, ecology, politic, geografic, and technical. To analyze this area, the method of area survey is used; it refers to standard criteria of assessing the object and the interest of natural tourism. To analysis economic value, techniques of travel cost is used. This research uses two approach of travel cost techniques (individual and zonation) including strategic plan of tourism development through multicriteria decision making analysis. There are three policy alternative to manage TWA Laut Pulau Weh which is status quo, marine protected area, and market development. The result of this research shows that the economic value of TWA Laut Pulau Weh with individual approach is more accurate than zonation approach. At present, the best policy alternative is assignment TWA Laut Pulau Weh as marine protected area on bases the economic benefit and utilization of the area for protection that involves active participation of the community and that serves educational products and learning activities, and also minimizes the negative impact of the activities in this area.
The CA can represent spatial dimension from a dynamic process. It is simple, transparent and strong in capacities for dynamic spatial simulation model where it is discrete at time dimension, place, and condition consists ofa regular grid of cells (Messina and Walsh 2000). CA has been utilized as prediction technique to study the impressive wide range of dynamic phenomena and also exudes superior performance in simulating land changes compared to conventional models (Hegde et al. 2008 in Wassahua 2010). According to Weng (2002), it has been successful in analyzing the direction, rate and spatial pattern from land use change by integrating the Markov Chain and CA. Integration of Markov chain and CA is known as an approach that considers the principles of coral reef change in a cell as being affected by surrounding cells (CA Principle), while changes in the future coral reef are determined by current and past conditions (Markov Chain). The Markov transition probabilities are used as basis for transitional provisions to the possible changes of each cell. Another parameter is the probability map that defines the direction of changes in surrounding cells.
research area has been formed of tuff rocks from the volcano. Based on the nature or characteristics of sandy clay soil texture, this layer is called an aquifer layer that can catch and pass water. Some points of the interpretation ofmarine sediments consist of: shale (limestone), rock salt and gravel. Sedimentary deposition rocks are sedimentary rocks that occur due to the deposition of erosion material, which consists of various types of particles that exist smooth, rough, heavy and some are light. Based on the value of resistivity, then a layer of rock is the hard rock due to precipitation and cementation, but has many cracks and fissures due to weathering so that rain water entering on this rock will mostly flow as surface runoff and most probably enter through fracture rock and escapes into layers below the surface or in the base layer of rock, the ground water will not be found at this layer. Possibility of water contained in the track 3 contains mineral salts as rocks constituent derived from marine sediments that contain mineral salts.
Ketika minyak masuk ke lingkungan laut, maka minyak dengan segera akan mengalami perubahan fisik dan kimia (Gambar 5). Diantara proses tersebut adalah menyebar dan adveksi (spreading and advection), larut (dissolution), menguap (Evaporation), memecah (dispersion) polymerase (polymerization), bercampur (emulsification), fotooksidasi (photooxidation), biodegradasi mikroba (microbial biodegradation), dan sedimentasi (sedimentation), Semua proses tersebut secara kolektif disebut dengan weathering of oil (Mukhtasor 2007; ITOPF 2002; Sloan, 1993; API, 1999; IMO, 1988). Faktor utama yang mempengaruhi weathering of oil adalah karakteristik fisik minyak seperti gaya grafitasi, viskositas, dan volatility, komposisi dan karakteristik kimia minyak, kondisi meteorologi (kondisi laut, sinar matahari dan temperatur udara), dan karakteristik air laut (gaya gravitasi, arus, suhu, bakteri, nutrient, oksigen terlarut, dan bahan terlarut lainnya) (IMO, 1988).
Dalam paradigm neoklasik, nilai ekonomi (economic value) dapat dilihat dari sisi kepuasan konsumen (preferences of consumers) dan keuntungan perusahan (profit of firms). Dalam hal ini konsep dasar yang digunakan adalah surplus ekonomi (economic surplus) yang di peroleh dari penjumlahan surplus konsumen (consumers surplus; CS) dan surplus oleh produsen (producers surplus; PS). Surplus konsumen terjadi apabila jumlah maksimum yang mampu konsumen bayar lebih besar dari jumlah yang secara aktual harus dibayar untuk mendapatkan barang atau jasa. Selisih jumlah tersebut di sebut consumers surplus (CS) dan tidak dibayarkan dalam konteks memperoleh barang yang diinginkan. Sementara itu, producers surplus (PS) terjadi ketika jumlah yang diterima oleh produser lebih besar dari jumlah yang harus dikeluarkan untuk memproduksi sebuah barang atau jasa. (Grigalunas dan Conger 1995; Freeman III 2003 dalam Adrianto 2004). Green (1992) diacu dalam Fauzi (2004) memandang bahwa menggunakan pendekatan surplus untuk mengukur manfaat sumberdaya alam merupakan pengukuran yang tepat karena sumberdaya dinilai berdasarkan alternative penggunaan terbaiknya (best alternative use). Surplus ekonomi dalam surplus konsumen, surplus produsen dan resource rent (rent sumberdaya).
