Abstract

The Mamuju River Estuary is an estuary whose role is to protect coastal ecosystems (mangroves, seagrasses, coral reefs) from the negative effects of intensification of land clearing upstream and coastal. Land clearing for various human needs encourages erosion resulting in high TSS (Total Suspended Solid) concentrations in river water bodies. This study aimed to determine the assimilation capacity of the Mamuju River estuary on TSS pollutants. The results showed that TSS concentrations still met the quality standard for marine biota (mangroves: <80 mg / l) with a lower distribution pattern when getting further away from the river mouth. The flushing time at the study site is 5.6 days so the river and seawater exchange is ± 65 times per year. The pollutant load was 586.11 tons/month. The value of the assimilation capacity reaches 255.57 tons/month. Based on these results it can be concluded that the Mamuju River estuary has experienced an overload of sediment.

Abstract

The presence of community activities along the coast, including tourism, can be a source of marine debris. Several coastal areas in Majene Regency have been made into tourist destinations, some of which are managed by the government while the majority are not. The research conducted aims to determine the characteristics of marine debris at beach tourism locations in Majene Regency. The research method used a quantitative approach with a field survey method to collect and observe the debris found at the observation sites, namely Barane Beach and Dato Beach, over a period of 15 days. Data analysis was carried out using descriptive statistics to determine the characteristics of marine debris based on type, size, and total mass of waste, as well as oceanographic characteristics. During the research period, a total of 837 pieces of debris were collected at Dato Beach and 2,265 pieces at the northern part of Barane Beach. The analysis results showed that the dominant type of waste at both locations was plastic, primarily beverage packaging, while the majority of the debris size was meso-debris. The total mass of marine debris at Barane Beach was 173.7 kg and 15.2 kg at Dato Beach. The types of debris were significantly different, while the size did not show a significant difference. The results highlight the importance of waste management, especially at beach tourism sites. Keywords: Beach tourism, Majene, Macro-debris, Marine debris, Plastic

Abstract

Samalona Island is a small island that administratively belongs to the inner zone of the Spermonde Islands region with low live coral cover. One effort to improve coral conditions is to carry out vertical transplantation, but hydro-oceanographic conditions are thought to be an inhibiting factor, including sediment. The research carried out aims to determine the suitability of oceanographic parameters, estimate sediment rates, and determine the phosphate and nitrate in sediments. The research method used a field experiment method by taking water and sediment samples and installing sediment traps for 15 days. The parameters measured in situ are temperature, pH, current speed, salinity, and dissolved oxygen, while the ex-situ test is the dry weight of sediment, TSS, nitrate, and phosphate concentrations. Data analysis uses descriptive statistics and is categorized according to the evaluation instrument used. The research results show that the values for temperature, pH, current speed, salinity, and dissolved oxygen meet the standard criteria for coral-based on PP 21/2022. The sediment rate during the research period was 0,003 – 0,015 gr/cm2/day, so it was categorized as having the potential damage to corals with a mild to severe impact level. The nitrate concentration in sediment ranges from 0,19 – 0,25 ppm while phosphate ranges from 0,35 – 0,72 ppm, so it can be said to be waters with a medium trophic level (mesotrophic). The current speeds and sediment rates potentially accelerate nutrient concentrations and cause sediment resuspension, thereby closing coral polyps, especially on corals closest to the substrate where vertical coral transplant installations are installed.

Abstract

Coastal communities in Tinambung Subdistrict, West Sulawesi utilize the potential of traditional aquaculture in their area. POKDAKAN Sipodalle is one of the traditional aquaculture systems with a polyculture method between milkfish and vanamei shrimp. However, the constraints faced are declining production yields as a result of crop failure due to commodities attacked by pests and diseases. One of the crucial things that need to be considered is water quality. The purpose of the activity is to increase knowledge for the Sipodalle' Fish Cultivation Group (POKDAKAN) about traditional pond water quality. The availability of water quality measurement tools managed by partners to increase productive cultivation. The activity was held on Monday, June 22, 2024 at the Tandung Village Office Hall, Tinambung District, West Sulawesi Province. The main participants of this service were Sipodalle' POKDAKAN, but also involved students and lecturers. The method applied was training using presentation methods and hands-on practice on how to use water quality checking tools. The results of the service activities showed an increase in farmers' knowledge related to traditional pond water quality management, techniques and SOPs for checking pond water quality. Furthermore, from this activity, the group of farmers obtained water quality checking tools and farmers already know how to use these tools. The results of the training opened the insight of farmers to pay attention to shrimp health through water quality control from water quality measurement tools provided including DO meters, pH meters, and thermometers. The end result is that farmers can monitor water quality to prevent pond water problems including optimizing growth and better yields. The community service activities carried out have been carried out smoothly and well. Partner problems related to lack of knowledge about water quality are overcome through understanding water quality parameters effectively.
