Abstract

Differences in the accumulation of lead heavy metal among plant organs (leaves, roots and rhizomes) were examined in the seagrass Thalassia hemprichii. Samples were taken from three coastal waters in Ambon Island, with total of nine sampling sites encompassing by seagrass distribution and also based on the land use. Lead heavy metal content was analyzed on the seagrass organs, water and sediment by atomic absoption spectrophotometer. It appeared that leaves, roots and rhizomes of T. hemprichii were able to uptake lead from water and sediment. Lead concentration was significantly higher in sediment and roots than water, leave and rhizome. Therefore, roots can be used to determine heavy metal of Pb distribution in coastal waters.

Abstract

Masyarakat pesisir menghasilkan limbah domestik anorganik maupun organik. Limbah tersebut sebagian tertahan dan terendapkan pada ekosistem lamun dan terdekomposisi yang menyebabkan pelepasan gas CO2. Penelitian ini bertujuan untuk menganalisis hubungan kepadatan lamun dan emisi gas CO2 yang ada di pesisir Negeri Waai, Kabupaten Maluku Tengah. Metode penelitian menggunakan sungkup silinder dan analisis emisi gas mengacu pada hasil analisa kromatografi gas (GC-MS). Hasil penelitian menunjukkan bahwa emisi CO2 terbesar pada stasiun I ditemukan pada spesies C. rotundata yaitu 55.91 mg/m2/jam dan yang terendah pada spesies E. acoroides yaitu 5.51 mg/m2/jam. Sementara pada stasiun II dan III, emisi terbesar ditemukan pada spesies T. hemprichii dengan nilai masing – masing sebesar 66.68 mg/m2/jam dan 33.57 mg/m2/jam. Sementara itu, hubungan kepadatan lamun jenis E. acoroides terhadap emisi CO2 diformulasikan dengan y = 11,318x – 8,3343 dan tingkat korelasi sangat kuat (r = 0,93). Hal yang serupa terlihat pada lamun jenis C. rotundata dan T. hemprichii dengan persamaan regresi linier masing – masing y = 14,284x + 10,751 (r = 0,9629) dan y = 19.085x (r = 0,96). Hal tersebut menunjukkan semakin padat lamun, maka semakin banyak bahan organik yang dapat didekomposisi untuk pembentukan emisi CO2. Selain itu, emisi yang tinggi juga dapat dipengaruhi oleh epifit mikroalga yang melakukan respirasi sehingga memicu peningkatan emisi CO2 di atmosif.

Abstract

The village of Talaga Ratu in Kairatu Village, West Seram Regency, Maluku Province, is known as a fishing village that produces demersal fish and marlin. However, fishing activities around coral reefs can damage fish habitats, making it essential to protect the environment so that fish populations remain diverse and abundant. One way to achieve this goal is by introducing a variety of fishing gear. The bale-bale technology, a trap fishing gear, offers a solution for the utilization of fish resources, especially flying fish eggs, which have high economic value. This community service activity aims to transfer knowledge about flying fish egg fishing technology as an alternative livelihood for fishermen, to optimally and sustainably utilize the fisheries potential. This activity includes lectures and training on making bale-bale. The results of the questionnaires showed an increase in community understanding of fishing gear diversification. This creates new business opportunities with high market value, which in turn can improve the economy and preserve the coastal island ecosystem.

Abstract

Abstrak Wilayah pesisir merupakan kawasan yang rentan terhadap berbagai ancaman bencana, seperti abrasi pantai, banjir rob, dan gelombang pasang, yang semakin meningkat akibat perubahan iklim dan tekanan aktivitas antropogenik. Salah satu upaya mitigasi bencana pesisir berbasis ekosistem yang efektif adalah melalui pelestarian dan rehabilitasi hutan mangrove. Namun demikian, rendahnya pemahaman dan keterlibatan generasi muda dalam upaya pengelolaan ekosistem pesisir masih menjadi tantangan dalam mewujudkan keberlanjutan mitigasi bencana. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk mengedukasi generasi muda mengenai peran strategis ekosistem mangrove dalam mitigasi bencana pesisir serta mengimplementasikan upaya perlindungan pantai melalui aksi penanaman mangrove di pesisir Negeri Hila. Kegiatan pengabdian kepada masyarakat ini dilaksanakan di Negeri Hila Kabupaten Maluku Tengah, dengan melibatkan siswa sekolah menengah atas sebagai mitra sasaran utama dengan jumlah peserta yang mengikuti kegiatan sebanyak 44 siswa. Metode pelaksanaan kegiatan menggunakan pendekatan edukatif, partisipatif, dan aplikatif. Kegiatan pengabdian dilaksanakan melalui tiga tahap, yaitu tahap persiapan, tahap pelaksanaan, dan tahap evaluasi. Hasil kegiatan menunjukkan adanya peningkatan pemahaman peserta sebesar 80% yang tercermin dari meningkatnya partisipasi dan ketepatan jawaban pada sesi tanya jawab setelah materi diberikan, serta tingginya antusiasme peserta dalam mengikuti seluruh rangkaian kegiatan. Selain itu, hasil monitoring pertumbuhan menunjukkan bahwa anakan mangrove yang bertahan mengalami perkembangan vegetatif yang baik, meskipun menghadapi berbagai tantangan lingkungan pesisir. Kegiatan ini memberikan kontribusi nyata terhadap rehabilitasi ekosistem mangrove serta memperkuat peran generasi muda sebagai agen perubahan dalam mendukung mitigasi bencana pesisir berbasis ekosistem secara berkelanjutan di Negeri Hila. Kata kunci: pesisir; mitigasi bencana; generasi muda; mangrove; Hila. Abstract Coastal areas are vulnerable to various disaster threats, such as coastal abrasion, tidal flooding, and tidal waves, which are increasing due to climate change and the pressure of anthropogenic activities. One effective ecosystem-based coastal disaster mitigation effort is through the preservation and rehabilitation of mangrove forests. However, the limited understanding and involvement of the younger generation in coastal ecosystem management efforts remain a challenge to realizing sustainable disaster mitigation. This community service activity aims to educate the younger generation about the strategic role of mangrove ecosystems in coastal disaster mitigation and implement coastal protection efforts through mangrove planting actions on the coast of Negeri Hila. This community service activity was carried out in Negeri Hila, Central Maluku Regency, targeting high school students as the main partners, with a total of 44 participants. The implementation method used an educational, participatory, and practical approach. The service activity was carried out in three stages: preparation, implementation, and evaluation. The results of the activity showed an 80% increase in participants' understanding, reflected in increased participation and answer accuracy during the question-and-answer session after the material was presented, as well as in participants' high enthusiasm for the entire series of activities.Furthermore, growth monitoring results indicate that the surviving mangrove seedlings are exhibiting good vegetative development despite various coastal environmental challenges. This activity makes a significant contribution to the rehabilitation of the mangrove ecosystem. It strengthens the role of the younger generation as agents of change in supporting sustainable, ecosystem-based coastal disaster mitigation in Hila State. Keywords: coastal; disaster mitigation; young generation; mangrove; Hila.
