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.
