Abstract

Hutan mangrove merupakan organisme atau tumbuhan yang mampu hidup pada salinitas yang relatif tinggi dan umumnya terdapat di seluruh pantai serta tumbuh berkembang pada daerah yang mempunyai pasang surut air laut. Penelitian bertujuan mengetahui kondisi ekosistem mangrove di Pesisir Selatan Purworejo.

Metode yang digunakan untuk pengambilan data adalah Metode Transek Garis dan Petak Contoh (Transect line plot). Hasil pengamatan ditemukan 3 jenis mangrove, yang ditemukan pada lokasi, yaitu: Rhizophora mucronata, Sonneratia alba dan Avicennia alba, terdapat juga mangrove Acanthus ilicifolius, dan Nhypa fruticans, diketahui juga kerapatan mangrove tertinggi pada stasiun III 9900 Ind/Ha, tutupan jenis Sonneratia alba 50.48, frekuensi tertinggi pada jenis mangrove Sonneratia alba dan Rhizophora mucronata. Indeks nilai penting tingkat pohon, pancang, dan semai yaitu tingkat pohon dari Sonneratia alba sebesar 215, tingkat pancang dari jenis Sonneratia alba sebesar 142, dan semai untuk Rhizophora mucronata dan Sonneratia alba sebesar 100.

Abstract

The aims of this study was to determine the distribution patterns and diversity of seagrass in Pallette and Tangkulara waters. This research was conducted for two months, from August to September 2019. Data collection was carried out at two points with three replications each. Seagrass data retrieval uses the line and quadrant transect method. The results showed that there were 5 species of seagrass found in the Pallette and Tangkulara Waters, namely Enhalus acoroides, Thalassia hemprichii, Halodule uninervis, Cymodocea rotundata, and Halophila sp. The diversity of seagrass species in the Pallette and Tangkulara Waters was in the low category. Distribution patterns of all species of seagrass Thalassia hemprichii Halodule uninervis, Cymodocea rotundata, Halophila sp. has a grouped distribution pattern value while for Enhalus acoroides the distribution pattern is equal.

Abstract

ABSTRACTSeagrass beds have an important role as the main source of primary productivity or organic matter producers, habitat for various biota, nursery grounds, spawning grounds, food sources for rare biota, and support for the diversity of marine biota species, as well as the economic value of seagrass ecosystem services. This study aims to determine the ecological index and distribution pattern of seagrass in the Banda Sea Aquatic Tourism Park (TWP). The method used is a line transect with a quadrant size of 50 cm x 50 cm that is placed perpendicular to the shoreline. The results showed that the seagrass diversity index at the study site consisted of 7 types of seagrass, namely Thalassia hemprichii, Enhalus acoroides, Cymodocea rotundata, Cymodocea serrulata, Halodule uninervis, Halophila ovalis, and Syringodium isoetifilium. The diversity index is categorized as moderate with a value of H' = 0.01-0.05, and a uniformity value of 0.71 has a high uniformity, which means that the number of individual species from one species to another is not much different from a stable environmental condition. The distribution pattern of seagrass with Id 1 is a grouped category. The physicochemical parameters obtained were in accordance with the growth of seagrass life.Keywords: Banda sea, Distribution pattern, Diversity, Dominance, Seagrass, Uniformity

Abstract

Small pelagic fisheries are highly sensitive to oceanographic variability, particularly sea surface temperature (SST) and primary productivity. The Banda Sea, located in eastern Indonesia, represents one of the country’s most productive yet understudied pelagic fishing grounds. This study examines the relationship between satellite-derived SST and chlorophyll-a concentration and the catch variability of Decapterus spp. in the Banda Sea. Monthly fisheries landing data from Banda Fishing Port in 2024 were integrated with Aqua MODIS Level 3–4 SST and chlorophyll-a products using spatial analysis and multiple linear regression. SST ranged from 25.3 to 33.6 °C, while chlorophyll-a concentrations varied between 0.04 and 13.78 mg.m-³, exhibiting strong seasonal patterns. The highest Decapterus catch (740,374 kg) occurred during the first transition season, coinciding with moderate SST and elevated chlorophyll-a levels. Regression analysis revealed strong correlations between catch and SST (r = 0.778) and chlorophyll-a (r = 0.775), indicating a significant influence of oceanographic conditions on fish availability. This study provides one of the first quantitative assessments linking satellite-derived environmental variability to small pelagic fisheries in the Banda Sea. The findings highlight the potential application of satellite-based monitoring to support ecosystem-based and climate-adaptive fisheries management in tropical marine environments.

Abstract

Mangrove ecosystems play a critical ecological role in maintaining coastal stability by serving as natural buffers against erosion, storing blue carbon, and providing habitat for marine organisms. In recent years, coastal zones in Bone Regency, South Sulawesi, have been degraded due to anthropogenic activities such as mangrove clearing, land conversion for aquaculture, and coastal infrastructure development. To address this issue, the Politeknik Kelautan dan Perikanan Bone in collaboration with Lembaga Survey Nypah Indonesia conducted a community service activity titled “Mangrove Rehabilitation Action: Growing Hope from the Coastline”. The activity was held on November 8th, 2025, in Tabu Hamlet, Waetuwo Village, Tanete Riattang Timur Sub-district, Bone Regency. Its objectives were to restore the mangrove ecosystem, raise community awareness of environmental conservation, and foster collaboration between vocational education institutions, environmental organizations, and local communities. A total of 100 participants—including students, lecturers, and residents—planted 2,000 seedlings of Rhizophora mucronata and Avicennia marina. The activity improved participants’ understanding of mangrove ecology, strengthened community-academic collaboration, and initiated plans for an eco-education area. This program serves as a participatory model for sustainable coastal ecosystem restoration.
