Abstract

Damage to mangrove ecosystems in coastal areas could result in biotic and abiotic physical changes. This damage might occur due to natural factors or human activities. Among the damaged mangrove ecosystems in East Kalimantan Province is Sebuntal Village. The aim of this research is to monitor and evaluate the survival rate of mangrove seedlings in Sebuntal village, Kutai Kartanegara Regency. The research population used in this research was all mangrove seedlings (Avicennia spp) planted during community service activities on August 9th, 2023. The research method used in this study was the survey method. It was found that the survival rate in this study was only 8.2%. This research showed that individual mangroves' survival rates were unsuccessful due to inappropriate planting times, hydro-oceanographic patterns that are poorly studied, and poor seed preparation.

Abstract

Mangrove are one of the important ecosystems in coastal areas that provide great benefits to other ecosystems. Excessive use of mengroves poses a threat to the growth of mengroves, one of which is the conversion of land, therefore it is necessary to make efforts to improve the mengrove ecosystem by planting mangroves. However, in the planting process, it is necessary to match the planting location, including the condition of the substrate. The aim of the research was to determine the percentage of substrate on the growth of Rhizophora sp. mangrove saplings. This research was conducted in June to October 2022 at Kuala Samboja beach, East Kalimantan. The research method is a survey method with a quantitative approach, measuring the success rate of mangrove life and analyzing substrate types. Based on the life success rate, the most mangrove saplings live at SR stations at 28 ind, ST stations at 20 ind and the least success at SD stations at 6 ind. Based on the research location, at SR and SK stations the silt type is dominated by 51-54%, at SL and ST stations the substrate type is dominated by silt (46-49%) and fine sand (39-49%) and at the SD station the substrate type is dominated by sand. (56%).

Abstract

The Pangempang waters, located within the estuarine area of Muara Badak, have experienced continuous coastline changes due to annual erosion. Monitoring water conditions in this region is essential to evaluate environmental suitability and detect potential threats. This study examined the physical and chemical properties of the water, following the guidelines of Government Regulation No. 22 of 2021. Observations were conducted at five selected sites: a shrimp pond, a river area adjacent to the pond, the river mouth near mining activities, a tourist area on Pangempang Island, and the outer section of the island near the dock, representing the Pangempang waters. Overall, the results indicate that water quality remains within acceptable limits for marine biota. However, certain parameters, such as temperature, salinity, and nitrate levels, deviated from the established standards. These variations are influenced by weather conditions, location, and potential organic waste input from activities along the study area.
