Abstract

Sampah plastik banyak dijumpai di berbagai wilayah pesisir, terbawa oleh gelombang arus dan pasang surut, serta kontribusi aktivitas daratan melalui sungai yang bermuara di laut. Ekosistem pesisir yang saat ini mengalami dampak peningkatan sampah plastik antara lain terumbu karang, padang lamun, pantai dan ekosistem mangrove. Ekosistem mangrove menjadi wilayah dengan ancaman akumulasi sampah makroplastik dengan jumlah sangat banyak dari berbagai aktivitas. Kawasan mangrove Karangsong di Kabupaten Indramayu merupakan ekosistem mangrove yang memiliki fungsi dan dikelola sebagai kawasan ekowisata. Riset ini bertujuan untuk mengetahui komposisi jenis dan kepadatan makroplastik di kawasan ekowisata Mangrove Karangsong. Penelitian menggunakan metode survei dengan plot transek 10 x 10 m2 secara stratified random sampling. Hasil penelitian ini menunjukkan makroplastik terbanyak merupakan jenis Polyethylene Terephthalate (PETE) sebesar 33,47% dengan kepadatan 5,43 potong/m2, sementara makroplastik paling sedikit dijumpai pada jenis Polyvinyl Chloride (PVC) sebesar 0,15% dengan kepadatan 0,01 potong/m2. Sebaran sampah makroplastik yang ditemukan umumnya terkumpul tersangkut pada sistem perakaran mangrove dan tertutup substrat sedimen. Jenis makroplastik yang ditemukan, mengindikasikan pentingnya pengelolaan sampah di kawasan ekowisata maupun dari sumber utama penghasil.

Abstract

Coral transplantation is a proven method for restoring degraded marine ecosystems affected by environmental changes and human activities. This study investigates how depth influences the growth and survival of Acropora formosa using the RakSagon structure at Gosong Pramuka Island, Seribu Islands. RakSagon is a hexagonal dome frame made of 10 mm iron, coated with a resin-catalyst mixture, and designed with two tiers to support coral fragment attachment. The observation spanned 378 days and was divided into three monitoring periods (t0–t3) with varying intervals. The study analyzed growth, survival, and effectiveness at depths of 3, 5, and 7 m. Additionally, the ratio between coral length and width (0.38–1.08) was measured to identify horizontal or vertical growth tendencies. The highest growth occurred at 7 m, averaging 1.41–1.74 cm.mo-1, while the lowest was at 3 m (0.68–0.99 cm.mo-1). Growth varied between observation periods, with the second interval showing the most notable increase. Fragment survival was evaluated using the Survival Rate (SR) and Mortality Index (MI); the MI value of 0.305 indicated moderate mortality, with a 69% success rate (25 of 36 fragments survived). A one-way ANOVA test revealed a significant difference in growth rates among the depths (P= 0.004), confirming that depth plays a crucial role in transplantation outcomes. The findings suggest that a depth of 7 m offers optimal conditions for coral growth and survival, providing valuable insights for future reef restoration programs and stakeholder initiatives.

Abstract

Land cover changes in the Pangandaran Coastal area are significantly influenced by tourism attractions as well as geographic and socio-economic dynamics. As one of the main coastal tourism destinations in West Java, Pangandaran receives more than 3.5 million tourists annually, which puts significant pressure on the coastal environment. This study uses land cover data from 2017–2023 analyzed using a regression and GIS approach, this study identifies spatial and temporal patterns of urban expansion and their implications for environmental sustainability. The results show that urbanization in Pangandaran is concentrated in the coastal lowlands, especially in Pangandaran and Sidamulih Districts, increasing vulnerability to natural disasters such as tsunamis. This expansion is triggered by the need for tourism infrastructure that often sacrifices natural ecosystems such as mangroves and coastal forests. In Cimerak and Parigi Districts, changes are more influenced by industrial and agro-industrial development, while growth in Cijulang is hampered by karst topography which is less supportive of urban development. Meanwhile, Kalipucang remains relatively natural due to geographic limitations that limit urban expansion. This study emphasizes the importance of sustainable coastal management, including adaptive spatial planning, conservation of critical ecosystems, and community-based initiatives to mitigate risks posed by unplanned urban expansion. The results of this study provide important insights for policymakers to balance tourism-based development with environmental resilience in the coastal area of Pangandaran.

Abstract

Global warming is a phenomenon of increasing the average temperature of the earth's surface. Carbon can be stored in various forms in ecosystems, one of which is the concept of blue carbon. This research aims to analyze the condition of the mangrove ecosystem and the potential for carbon storage in the mangrove forest rehabilitation area in Sebele Village, Karimun Regency, Riau Islands. This research was conducted from October 2024 to July 2025 in the mangrove forest rehabilitation area of Sebele Village, Riau Islands Province. The method used in this research is the survey method. Standing biomass data was obtained using allometric equations. The research results show that the level of tree density in the mangrove forest rehabilitation area of Sebele Village is in the Sparse category. At the tree level, it is dominated by the Xylocarpus granatum species, while at the sapling level it is dominated by the Rhizophora mucronataspecies. The highest carbon storage value is found in the Avicennia marina species with a carbon storage value of 14.44 tons/ha. And the potential carbon storage from the calculation results obtained a carbon storage value of 61.43 tons/ha. The carbon storage value is directly proportional to the standing biomass. The greater the standing biomass, the greater the carbon stored.

Abstract

The Nizam Zachman Ocean Fishing Port (PPS) in Jakarta is a key fisheries hub with many cast nets and high squid landings. However, overfishing in several Fisheries Management Areas (WPP) requires an evaluation of fishing gear selectivity. This research aims to analyze the size distribution of squid (Uroteuthis chinensis) caught, cast net selectivity, and growth, mortality, and recruitment parameters. Data were analyzed using length-frequency distributions and FISAT II software. Results showed that squid mantle lengths ranged from 15–41 cm, with a modal shift from 18 cm in December 2024 to 24 cm in January 2025. The first-capture length (Lc50%) of 26.90 cm, greater than half the maximum length, suggests that cast nets tend to catch appropriately-sized individuals. The selectivity factor (SF) was 7.06, indicating high selectivity. Growth analysis using the Von Bertalanffy model showed an asymptotic length (L∞) of 41 cm, a growth rate (K) of 1.01/year, and a theoretical zero-length time (t₀) of –0.14. Total mortality was 2.02/year, with natural and fishing mortality at 1,10 and 0,92/year, respectively; exploitation rate (0,45) remained below the optimal 0,5. The recruitment pattern shows the highest peak occurred in June (26.89%). Key words: long frequency histogram, population dynamics, size distribution
