Abstract

Plankton is an organism that lives floating in the water whose movement is influenced by the current. The presence of plankton in a water body can be used as a bioindicator because it has a high level of sensitivity and is also influenced by changes in water conditions. Changes in water conditions can be caused by human activities. The purpose of this study was to determine the structure of the plankton community in seagrass beds in the waters of Selangan Hamlet. This research was conducted in November-December 2019 in Selangan Hamlet, Bontang City, East Kalimantan. Data analysis includes abundance, diversity index, uniformity index and dominance index. The results showed that the composition of plankton species found in the waters of Selangan Hamlet at 4 stations with conditions at high tide and low tide obtained 13 plankton classes namely Cyanophyceae, Bacillariophyceae, Oligotrichea, Dinophyceae, Foraminifera, Chlorophyceae, Trebouxiophyceae, Conjugatophyceae, Hexanauplia, Crustaceae, Gastropoda, Tubulinea, and Euglenoidea consisting of 47 plankton species. Plankton abundance ranged from 893-2,514 ind/L. The structure of the plankton community in the waters of Selangan Hamlet has a Diversity Index (H') value in the medium category with a range of values of 2.28-2.99, Diversity Index (E) category of stable plankton communities with a range of values of 0.82-0.95, and Dominance Index (C) category there is no dominant genus at each research station with a range of values of 0.06-0.14.

Abstract

Seagrass has clear economic benefits in supporting the availability of various commercial fish species and also serves multiple ecological functions. The presence of seagrass in marine waters can act as a bioindicator of heavy metal pollution, as it can absorb and accumulate contaminants. Until now, the exact concentration of heavy metals in the water and sediment of seagrass beds in Tihi-Tihi Village, Bontang City, has not been clearly known. This study aims to determine the content of heavy metals (Pb, Cu, Mn, and Zn) in the water and sediment of seagrass beds in Tihi-Tihi Village, Bontang City, East Kalimantan. The results showed that the concentrations of heavy metals (Pb, Cu, Mn, and Zn) in the water were the same across all stations, ranging between <0.001–<0.003 mg/L, which is below the quality standards set by the government. Lead (Pb) is the heavy metal of most concern due to its concentration falling within the Severe Effect Level. Further studies are needed to investigate the potential impacts of the high concentration of Pb in the sediment of this seagrass bed.

Abstract

This study aims to determine the socio-economic conditions and survival strategies of gillnet fishermen households in maintaining their lives. The research was conducted for 11 months from July to May 2024 in Bontang Kuala Village, North Bontang District, Bontang City.  The method used in sampling fishermen is simple random sampling with a total of 34 respondents. The analysis method uses qualitative descriptive analysis. The results showed that the socio-economic conditions of the majority of gill net fishermen were productive age 53-59 years, the average education level was elementary school 26 people, fishermen's income ranged from IDR 420,000 - IDR 3,000,000 per month with an average per fisherman IDR 2,031,470. Their status is owner fishermen with fishing fleets in the form of boats with no engine, boats with ketinting engines and boats or boats with dompeng engines. Fishermen's residences are generally semi-permanent houses with good physical conditions and the land ownership status of the house building is Hak Guna Bagunan (HGB). Fishermen's survival strategies are carried out in three ways, namely, active strategies by doing side jobs, optimising the role of family members (wife and children) and increasing working hours at sea. Passive strategies, reducing the cost of food, clothing, education and setting aside money or saving money from fish sales. Network strategies, making loans through horizontal social networks (family) and vertical social networks (collectors), as well as economic or financial institutions, such as cooperatives, banks, People's Business Credit (PBC) through fisheries organisations and utilising poverty programs.

Abstract

Microplastics present in the environment, particularly in sediments, pose potential threats to aquatic organisms, as they can impair organ function when ingested. This study aims to assess the abundance, types, and colors of microplastics in the sediments of the artificial pond at Mulawarman University, Samarinda. The research employed a purposive sampling method. The Faculty of Agriculture pond had a higher microplastic abundance compared to the UNMUL HUB pond. Nonetheless, statistical analysis using a t-test showed no significant difference in microplastic levels between the two sites at Mulawarman University, Samarinda (p-value > 0.05). Overall, the artificial ponds at Mulawarman University, East Kalimantan, contained an average of 275 particles of microplastic per kilogram of dry sediment. Specifically, the Faculty of Agriculture pond had 161.25 particles/kg, while the UNMUL HUB pond had 113.75 particles/kg. The microplastics found consisted of fibers, fragments, films, and pellets, with colors including black, blue, red, brown, yellow, and white.
