Abstract

Fishery waste management activities are an important issue in maintaining the sustainability of the coastal environment. In the Tanjung Luar area, East Lombok, dense fishing activities have the potential to produce large amounts of organic and inorganic waste. This community service activity aims to increase fishermen's awareness of the impacts of fishery waste and the importance of sustainable management through socialization activities. The methods used are counseling and participatory group discussions with local fishermen. The results of the activity showed an increase in participants' knowledge about the types of waste and how to handle it. This activity is expected to be the first step towards more environmentally friendly fisheries practices in coastal areas.

Abstract

Coastal waters are essential to both marine ecosystems and the livelihoods of local communities, yet they are increasingly vulnerable to degradation due to anthropogenic activities. This study aims to evaluate the water quality of the coastal waters in Poja Village, Sape District, Bima Regency, to assess the environmental health and the impact of local human activities on marine ecosystems. A descriptive-quantitative approach was employed, with water samples collected from seven locations to analyze physical and chemical parameters, including temperature, pH, salinity, ammonia, nitrite, nitrate, and water visibility. The findings revealed that the water quality remains in a favorable condition, with temperatures ranging from 28.3°C to 30.0°C, pH values between 7.3 and 7.8, and salinity within acceptable standards. Nitrate concentrations were recorded between 5 and 10 ppm, indicating some anthropogenic influence, while ammonia and nitrite were undetectable. In conclusion, the coastal waters of Poja Village exhibit good quality, supporting marine ecosystems and local fishing activities. Regular monitoring is essential to ensure the sustainable management and conservation of marine resources.

Abstract

This study examines the growth of the Pharella acutidens clam in mangrove ecosystem of  Cempi Bay, which has a habit of living in the substrate with a vertical shell position. These clams emit siphons when the hole they live is waterlogged to obtain food. Field observations showed that the depth of the Pharella acutidens hole was strongly influenced by the tide. During high tide, the clam moves close to the surface up to 10 cm from the substrate, while during low tide, the clam can bury itself to a maximum depth of 70 cm and a minimum of 25 cm. The minimum shell length recorded was 4.90 cm, while the maximum length of Pharella acutidens clams was 9.30 cm. the highest L∞ (9,71) and K (0.45) is found in locations that are densely vegetated, the lowest L∞ (7,88) and K (0.38) is found in low vegetated locations. There is something interesting because the low-vegetated location and higher disturbance has a relatively high recruitment value.

Abstract

Coastal waters play a vital role in supporting ecological balance and socio-economic activities in island regions such as Lombok, Indonesia. Rapid tourism growth, coastal settlements, and marine transportation have increased environmental pressures on these ecosystems. This study aims to provide a comprehensive overview of the ecological condition of Lombok’s coastal waters through a Systematic Literature Review (SLR) of ten scientific articles published between 2014 and 2025. The review follows the PRISMA protocol, focusing on themes of water quality, mangrove and coral reef ecosystems, pollution, and coastal management. The analysis reveals that most coastal areas in Lombok still meet the national seawater quality standards (PP No. 22/2021), with parameters such as temperature, salinity, and dissolved oxygen remaining within optimal ranges. However, nutrient enrichment and trace metal accumulation have been detected in high-activity zones like Mandalika and Teluk Kodek. Mangrove and coral ecosystems in Gili Petagan and Gili Matra remain relatively healthy, supporting conservation and eco-tourism potential. The findings emphasize the need for integrated, science-based management involving community participation to maintain ecological stability while promoting sustainable blue economy development toward Indonesia’s 2045 Vision.
