There is a rising concern regarding the accumulation of microplastics (MPs) in the aquatic ecosystems. Monitoring effort is crucial to understand the concentration and distribution of MPs. The objective of this paper is to mapping the concentration and characteristics of MPs distributed/deposited in estuary, coast, sediment, and marine organism in Indonesia based on data published from the last five years. In the estuary and coast, the highest MPs concentration were located in Brantas River, East Java, around 133 - 5467 particles/m3. In sediment, the highly amount of MP’s, 1136 particles/kg, were found in Kawal village, Bintan Island, Riau. In marine organism, horn snail (Telescopium telescopium) from Rambut Island, Jakarta Bay contained the highest amount of MP’s around 764.81 particles/individual . MPs were commonly found in fragments, fibers, and films with size ranging between 1 μm - 5 mm. Those MPs are mostly made of polyethylene (PE), polypropylene (PP), polystyrene (PS) and polyesters (PES). The data summary obtained in this study could be useful for understanding the sources of MPs as well as monitoring the environmental condition in the aquatic ecosystems.

Siganus sp is one of the leading commodities that have high economic value. Until now, the market demand for Siganus sp continues to increase so that the prospect of its cultivation is very promising. The problem that arises specifically for fishermen in the coastal sub-district of Maros Regency is that there is no data and knowledge about suitable locations for the cultivation of Siganus sp. This study aims to determine the area that is suitable for cultivation of Siganus sp in the coastal district of Maros Regency. Data collection techniques were carried out by literature studies and direct field observations by taking coordinates and measuring oceanographic parameters (temperature, salinity, pH, brightness, dissolved oxygen, depth, current velocity). Water quality data were analyzed by weighting, overlaying and layout using GIS analysis. This research was conducted in the waters of the coastal sub-district of Maros Regency in January-August 2021. The results showed that the location of the suitability of Siganus sp aquaculture waters in the coastal sub-district of Maros Regency obtained suitable waters (S) for the development of Siganus sp cultivation covering an area of 630.36 ha and waters that are not suitable (N) for the development of cultivation Siganus sp covering an area of 681.2 ha.

This study aimed to analyze the income level of fishing gear fishers and analyze the welfare level of fishing gear fishers in Barombong Village, Makassar City, South Sulawesi Province. Techniques data collection is done using observation, interviews using questionnaires and documentation. The type of data collected is data that is by the prosperous family indicators based on the 2019 BPS, namely; income data, household consumption or expenditure data, living conditions, household facilities, the health of family members, ease of obtaining health services, ease of entering children into education level and ease of securing transportation facilities. This research was carried out in Barombong Kacan Tamalate Village, Makassar City, in February - April 2021. The results showed that fishing gear fishermen respondents' average income per year was Rp. 36,905,833/year or Rp. 3,075,486/month and fall into the category of low-income level. Based on the 2019 BPS indicators, it is known that 24 respondents from 10 groups of fishing gear fishermen in the Barombong Village, Makassar City belong to the high welfare level as many as 8 respondents (33%) with a total indicator score of 20. As many as 16 respondents (67%) belong to the moderate welfare level with total indicator scores ranging from 18-19. Based on these results, it can be seen that the standard of living of fishing gear fishers in the Barombong Village, Makassar City, is classified as prosperous, with the fact that the income of respondents is low. Still, most of the life support has been provided by the government, especially in the health and education sectors, so that it does not burden household expenses. The addition of new jobs needs to be done as another source of income to increase welfare from a moderate level of interest to a high level of welfare.
本研究旨在分析南苏拉威西省望加锡市Barombong村渔具渔民的收入水平和渔具渔民的福利水平。技术数据收集是通过观察、访谈、问卷调查和文件来完成的。收集的数据类型是基于2019年BPS的富裕家庭指标的数据，即;收入数据、家庭消费或支出数据、生活条件、家庭设施、家庭成员健康、获得保健服务的难易程度、儿童接受教育的难易程度和获得交通设施的难易程度。这项研究于2021年2月至4月在望加锡市Barombong Kacan Tamalate村进行。结果表明，渔具渔民受访者的年平均收入为36,905,833 Rp /年或3,075,486 Rp /月，属于低收入水平。根据2019年BPS指标，在望加锡市巴隆峰村的10组渔具渔民中，有24名回访者属于高福利水平，多达8名回访者(33%)，总指标得分为20分。总体指标得分在18 ~ 19分之间，属于中等福利阶层的应答者达16人(67%)。根据这些结果可以看出，望加锡市Barombong村渔具渔民的生活水平属于富裕，但调查对象的收入较低。尽管如此，大多数生命支持都是由政府提供的，特别是在卫生和教育部门，因此不会给家庭开支带来负担。增加新的工作岗位需要作为另一个收入来源，将福利从中等兴趣水平提高到高福利水平。

Business Crab (Portunus pelagicus) Kawal Village waters are waters located in the Gunung Kijang area, Bintan Regency, Riau Islands Province. High market demand for crab fishery commodities that triggers excessive exploitation so that it can have an impact on the sustainability of crab resources. This study aims to determine the condition of the sex ratio and the pattern of crab growth in the waters of Kawal Village, Bintan Regency. The method used in this study is a survey method. The sampling technique was carried out using a random census, in which the researcher immediately went down to the field to take a sample of 176 crabs. The results showed a good sex ratio for female crabs at 52% and male crabs at 48%, which has calculated the Chi-square test which between females and males has a balanced ratio, which results in: X2 count of 33, 2 while X table is 74,975 which if X2 count < X table: male and female sex ratio is balanced. The growth pattern of both female and male crabs in the waters of Kawal Village, Bintan Regency has a negative allometric character where the growth pattern of carapace width is greater than weight growth.

Pangkil Village is one of the areas located on the coast of Bintan Island, Teluk Bintan District. This island has an aquatic ecosystem with abundant marine resources, one of which is the mangrove ecosystem. Mangroves are the main supporting ecosystem for life activities in coastal areas that play an important role in maintaining the balance of environmental biological cycles. This study aims to determine the condition, distribution and density level of mangroves in the waters of Pangkil Village. This research was conducted in February-March 2021. The research method is purposive sampling, which means that the research station points are chosen intentionally based on the consideration of the condition of the existence of mangroves or the density of mangroves. The research station points were determined as many as 8 stations, at each station consisting of transects and at each transect consisting of 3 sample plot plots (Transect Line Plot). The density level data was collected using a line transect measuring 10x102 which was drawn from the sea to the land and the distribution of mangroves using lansat-8 imagery. The level of mangrove density in the waters of Pangkil Village is still quite good. The results of the research on the level of mangrove density in the waters of Pangkil Village are classified as good with the distribution of mangrove areas in the waters of Pangkil Village covering an area of 40.23 ha, with an average density level of 1,033 ind/ha per station to 1,733 ind/ha. with medium and solid status based on the Decree of the Minister of the Environment No. 201 year 2004.
