Tirta Samudra Beach is a beach that is quite famous and has become a mainstay of Jepara Regency so that it becomes a fairly popular tourist destination, not only for the people of Jepara, but also most of the population of Central Java and even outside the province. Currently, tourism activities on Tirta Samudra Beach are very limited to just recreation, enjoying the panoramic beauty of the coast, and swimming activities. While there is still a lot of physical potential in the form of a coastal environment that has not been fully utilized, such as water sports tourism, vacant land, and so on. Its natural beauty is in great demand by many people, therefore it can cause environmental damage because it is often visited by visitors. Therefore, it is necessary to analyze and study the tourism industry strategy to find out what is needed to keep attracting visitors and minimize environmental damage. The purpose of this study is to analyze the potential and to anticipate the development strategy of tourism objects in Tirta Samudra Beach. The method used is a field survey with data collection using observations, questionnaires, and documentation to tourists and local managers.

The mangrove ecosystem is a coastal ecosystem that is important for humans. Mangroves absorb carbon in the atmosphere and store it in biomass or sediment. So, in other words, mangroves play a significant role in mitigating global climate change. This study aimed to examine the structure of the mangrove ecosystem composition and estimate standing carbon stocks on Sangiang Island, Banten. The data taken was for the categories of trees, saplings, and seedlings (consisting of mangrove species, DBH, and height). The study was conducted at three stations with three replications for each station. The allometric formula obtained the estimated carbon stock from the stand biomass value. The results showed that 11 species of mangrove species were found with an average density of 1266 ind/ha (trees), 3733 ind/ha (saplings), and <70% (seedlings). Then the estimated average carbon stock in Sangiang Island, Banten is 271.29 tons/ha.

Tunda Island is one of a group of islands located in the northern area of Banten Province. In the eastern and southern parts of Tunda Island, there is a mangrove ecosystem which is a habitat for various organisms, one of which is gastropods. In the mangrove ecosystem, some gastropods live on the roots, stems, and leaves of mangroves by sticking and climbing, clinging to dead wood, to the muddy ground. It is necessary to know the type composition and distribution of gastropods in the mangrove ecosystem found on Tunda Island, Serang Regency, Banten. Gastropod sampling was carried out on a 5 x 5 m2 plot at the lowest tide. All types of gastropods found in the plots were taken by hand. The gastropod samples obtained were then cleaned and put in a sample bottle, then given a 70% alcohol solution as initial preservation for further identification at the Laboratory of Dry Hydrobiology, Marine Science and Technology, FPIK, Bogor Agricultural University. There are 19 types of gastropods found in the mangrove ecosystem of Tunda Island from 11 families, including: Cerithidea cingulata, Telescopium telescopium, Terebralia sulcata, Terebralia palustris, Cerithium kobelti, Chicoreus capucinus, Coralliophila persica, Littoraria scabra, Mitrella puella, Xenorita plana. indica, Clea helena, Morula biconica, Phos senticosus, Fissilabia decollate, Monodonta canalifera, Imbricaria vanicorensis.

The Covid-19 pandemic has had a major economic impact on the community, including those on small islands. Related to this, the government as a decision maker in various programs to improve community welfare needs to think about effective and efficient forms of programs to intervene in small island communities. One of the government's basis for making these decisions is through the existing conditions of community economic resilience. Without this information and analysis regarding the existing conditions, the government will find it difficult to implement targeted intervention programs. This study aims to determine the level of economic resilience of the people of the small islands of Gili Matra as destinations that are most affected by the Covid-19 pandemic, as well as to formulate interventions that will be carried out to increase the resilience and adaptive capacity of the people of small islands in the face of the Covid-19 pandemic. The results of this study indicate that the era of the Covid-19 pandemic has had a significant impact on the economic resilience of small island communities, including the Gili Matra TWP area. During the Covid-19 pandemic, there was a weakening of business, loss of assets, loss of livelihood, loss of markets, inability to produce resulting in loss of income, so an adaptation strategy was needed to face threats and opportunities to the economic sustainability of the Gili Matra TWP community. Economic assistance for communities affected by Covid-19 is one solution in increasing the adaptability of the Gili Matra TWP community. There are five forms of intervention that need to be carried out in economic assistance, namely: 1) Strengthening/Formation of Joint Business Groups, 2) Strengthening group capacity, 3) Assistance with production equipment and production raw materials, 4) Repackaging rebranding and business nameplates, and 5) Online Marketing Training.

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.

The mangrove ecosystem is one of the ecosystems with high productivity due to the input of organic matter from litter. Litter production is the main supporter of fisheries potential, namely as a food source for aquatic biota. On Manomadehe Island, the community still continues to cut down mangroves to be used as firewood and building materials. Activities like this will result in damage to the mangrove forest and a decrease in the amount of litter production. Research objectives 1. To determine the amount of mangrove leaf litter production on Manomadehe Island, South Jailolo District, West Halmahera Regency. 2. Knowing the rate of decomposition of mangrove leaf litter on Manomadehe Island, South Jailolo District, West Halmahera Regency. This research was carried out in June-August 2020 using the purposive sampling method to determine stations, density (line transect plot), and litter-trap litter production. In general, the composition of mangrove species found at the study site on Manomadehe Island consisted of 3 families with 6 species (Rhizophora stylosa, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, Avicennia marina, Avicennia lanata). Total production of mangrove leaf litter is 1276,59 grams/m2/60days, the highest is at Station 1 589,80 grams/m2/60days, Station 2 is 419,59 grams/m2/60days, Station 3267,21 grams/m2/60days. The highest litter contributor was Rhizophora stylosa 424,25 grams/m2/60days. Rhizophora apiculata 340,79 grams/m2/60days, Sonneratia alba 336,94 grams/m2/60days, Rhizophora mucronata 99,26 grams/m2/60days, Avicennia lanata 38,55 grams/m2/60days, Avicennia marina species are 36,80 grams/m2/60days.
红树林生态系统是具有高生产力的生态系统之一，主要得益于凋落物有机质的输入。凋落物生产是渔业潜力的主要支持者，即作为水生生物群的食物来源。在Manomadehe岛上，社区仍在继续砍伐红树林，用作柴火和建筑材料。这样的活动将导致红树林的破坏和凋落物产量的减少。研究目的目的:确定西哈马赫拉县南Jailolo区Manomadehe岛红树林凋落叶产量。了解西哈马黑拉摄政区南Jailolo区Manomadehe岛上红树林凋落叶的分解速度。本研究于2020年6月至8月采用目的抽样方法进行，以确定站点、密度(样线样地)和凋落物诱捕器凋落物产量。总体而言，Manomadehe岛研究地点红树林的物种组成包括3科6种(茎尖、尖根、粗根、海桑、滨海、大叶海桑)。红树林凋落叶总产量为1276、59 g /m2/60d，其中站1 589、80 g /m2/60d产量最高，站2 419、59 g /m2/60d产量最高，站3267、21 g /m2/60d产量最高。对凋落物贡献最大的是茎尖根霉424,25 g /m2/60d。尖根霉340、79克/m2/60天，海桑336、94克/m2/60天，长根霉99、26克/m2/60天，海棠38、55克/m2/60天，海棠36、80克/m2/60天。
