Lomek fish is a typical fish that is often found in the province of Riau, one of which is in Dumai. The stable production of lomek fishery in Dumai makes it necessary to have more management so that the catches obtained by fishermen are not only sold in the form of raw processing, but also in ready-to-sell products. The high potential of fish resources makes several products appear, one of which is churros made from lomek fish. This product diversification is also expected to improve the economy in Dumai City through MSMEs. The purpose of this study is to recommend a fish churros business development strategy using SWOT analysis. The results obtained are fish churros business based on SWOT analysis is in quadrant 1, namely the processing business must carry out aggressive efforts by taking advantage of strengths and opportunities, strategic recommendations that can be carried out are food certification, product registration in delivery services, collaboration and marketing in several markets. place, adding some variety to the taste of the product and providing price promotions to consumersKey Words: SWOT; Strategy; Business; Diversiification

Climate change has been global warming as greenhouse gas emissions (GHG) caused by increased emissions of gases such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and chlorofluorocarbons (CFC) so that solar energy is trapped in the earth's atmosphere. Various efforts have been made to reduce the impact of climate change, one of which is by utilizing the oceans and coastal ecosystems as natural CO2 sinks. The purpose of this study was to determine the density, carbon sequestration in biomass and the habitat conditions of seagrass beds conducted in March 2021 in Youtefa Bay, Jayapura Papua. Seagrass density was carried out using the quadrant transect method, carbon content analysis was carried out using the ashing method. The results of the study found 1 species of seagrass, namely Enhalus acoroides, the density values ranged from 85.69 ind/m² - 102.56 ind/m². the value of biomass under the substrate ranged from 3321.75 - 3580.75 gbk/m² which was greater than the value of the biomass above the substrate, which ranged from 720.19 to 955.79 gbk/m², followed by the value of the carbon content under the substrate (roots and rhizomes) ranged from 87.30 – 96.92 g C/m² while the value of carbon content above the substrate (leaf) ranged from 35.99 – 44.84 g C/m².

Osapan Beach is a beach tourism object located in Demta District, Jayapura Regency, which is currently still in the early stages of development to become a tourist spot. However, the existence of Osapan Beach is not widely known by the people in the City and Regency of Jayapura. Until now, there is no data or results of scientific studies that can be used as a reference for the development and management of Osapan Beach in the future. This study aims to determine the level of suitability of the area and carrying capacity and to find out how the perception of the community and tourists in the development of Osapan Beach as an eco-tourism location. This research was conducted from January to June 2021. The methods used in this study include the observation method (observation and direct collection of tourism suitability parameter data), interviews with respondents (asking several questions using questionnaires to 35 respondents and documentation (recording data, taking research drawings/photos). The results showed that the tourism suitability index (IKW) for all ecotourism suitability parameters at Osapan Beach, station 1 and station 2 had the same value, namely 89.28% (Highly Appropriate/S1), station 3 had a value of 95.23% (Very Appropriate/S1) and station 4 has a score of 82.14% (Suitable/S2). The carrying capacity of Osapan Beach as an ecotourism location is 21 people/day. Most of the respondents think that Osapan Beach deserves to be used as an ecotourism area where Osapan Beach has an attraction and has the potential to support the economy of the Yakore Village community.

Sedimentation can be one of the factors that limit coral life because it can cover coral polyps, in high numbers it can even cause coral death. The purpose of this study was to determine the rate of sedimentation in the coral reef ecosystem and to determine the condition of coral reef cover in the waters of Kampung Yakore. This research was carried out from January to May 2021. The method used in this study was to collect sediment in a sediment trap for 14 days and the LIT (Line Intercept Transect) method to observe the condition of live coral cover. Data were collected at 3 stations at a depth of 3 m and 5 m. The results showed that the sedimentation rate in the waters of Kampung Yakore was moderate to very heavy where the highest sedimentation rate was at station 3 with a depth of 5 m. The sedimentation rate ranged from 30.28 – 67.74 mg/cm²/day at a depth of 3 m. Meanwhile, at a depth of 5 m, the sedimentation rate ranged from 68.30 – 133.21 mg/cm²/day. This shows that the sedimentation rate in the waters of Kampung Yakore is at a very heavy impact level. It is suspected that the high sedimentation rate is caused by the time when data collection is carried out during the rainy season so that the river discharge is getting bigger and carrying sediment to the sea. The percentage of live coral cover in the waters of Kampung Yakore was classified as "moderate" to "good" with percentages ranging from 39.28% - 71.76% at a depth of 3 m and ranging from 30.7% - 56.12% at a depth of 5 m. The highest percentage of the cover was at station 2 with a depth of 3 m, which was 71.76%.Key Words: Sedimentation Rate; Coral Reef Ecosystem; Coral Cover; Yakore VIllage

Mangrove and seagrass ecosystems have important functions and roles in coastal and marine waters, as an ecological buffer system, habitat for various types of fish and aquatic biota, as well as a biosystem of energy flow for the aquatic environment in Youtefa Bay, Jayapura. This study was conducted to calculate and review the mangrove and seagrass ecosystem fisheries affected by ecosystem damage and pollution. Data collection using fishing methods, vertical plankton sampling, and measurement of water quality parameters. Analysis of the data used: (1) analysis of the level of diversity using the Shannon-Wiener index, (2) analysis of dominance, (3) analysis of species composition (4) analysis of fish abundance, and (5) descriptive analysis. This study succeeded in obtaining 99 fish samples from 11 families and 12 fish species. The level of diversity is moderate (2.21) and the abundance of species is 73 individuals/ha. There were 5 dominant fish species associated with the ecotone zone of mangrove and seagrass ecosystems, namely Valamungil buchanani, Chanos-chanos, Gerres oyena, Pempheris schwenkii, and Pentapodus aureofasciatus. More fish were found in the seagrass and coral reef ecotone zones, namely 180 fish individuals caught from 11 families and 17 species of fish, with a high level of diversity (2.77), an abundance of species as many as 150 individuals/ha, and no dominant species. The review study of fishery resources in the ecotone zone shows very rapid degradation and decline in diversity, composition, and abundance in the waters of the mangrove, seagrass, and reef ecosystems of Youtefa Bay, Jayapura.Key Words: Fisheries; Mangroves; Seagrass; Youtefa Bay; Jayapura

This study aims to determine the diversity, abundance, and economic value of target fish in the mangrove ecosystem of Demta Bay, Jayapura Regency, Papua Province, Indonesia. This research was conducted from August 2019 to January 2020. The research method used was the field observation method, the purposive sampling method, and the method of interviewing the community. The target fish diversity index value at all stations is 1.92. Based on the diversity index criteria it can be seen that the diversity of target fish in the mangrove ecosystem of Demta Bay is classified as moderate. The results of data analysis obtained the value of abundance from all stations is 1086.67. The target fish diversity value and the target fish abundance value indicate that the number of target fish groups in the waters of Demta Bay is quite good. There are several species of target fish that have high prices, namely Ephinephelus quoyanus with the local name Uwga and Cephalopholis microprion with the local name Padamuw. Besides, there are also several species of target fish that have a fairly low selling price, including Pristiapogon fraenatus (Dakai Tipir), Nematolosa come (Pylair), Lactarius lactarius (Lema), Leighnathus equluus (Awara), Valamugil buchanani (Amakai) and Upeneus vittatus (Marep).Keywords: Diversity index; Economic value; Fish target; Demta Bay
