Abstract
Mangrove menyumbangkan nutrisi penting bagi tanah melalui serasah yang jatuh ke dalam sedimen. Secara umum, jamur merupakan komponen tanah yang penting karena keduanya pengurai dan simbion tumbuhan, memainkan peran utama dalam ekologi dan proses biogeokimia. Dekomposisi serasah daun, sebagai bagian dari produktivitas kawasan, menghasilkan unsur hara esensial sederhana yang dimanfaatkan untuk menopang pertumbuhan bakau dan organisme di ekosistem mangrove. Serasah daun sebagai komponen utama yang juga merupakan sumber karbohidrat dan protein serta unsur-unsur hara yang dibutuhkan untuk pertumbuhan vegetasi di lingkungan pesisir. Pengabdian masyarakat dilaksanakan dari Agustus sampai November 2024. Tujuan pengabdian ini adalah untuk meningkatkan animo masyarakat pesisir untuk menanam mangrove. Penelitian ini menggunakan kantong serasah yang terbuat dari nilon, serasah daun Avicennia marina, jenis fungi Aspergillus sp 1. serta bibit Ikan Bandeng. Pengambilan kantong berisi serasah daun yang telah diaplikasi fungi Aspergillus sp 1. dilakukan setiap 15 hari sekali. Pada saat ini juga dilakukan pengukuran berat bobot ikan bandeng sampai 6 kali pengamatan. Penelitian ini mendapatkan bobot Ikan Bandeng pada serasah mangrove yang diberi fungi Aspergillus sp 1. lebih besar dibanding Ikan Bandeng yang dijadikan kontrol.
Mangroves contribute important nutrients to the soil through litter that falls into the sediment. In general, fungi are important soil components as they are both decomposers and plant symbionts, playing a major role in ecology and biogeochemical processes. Decomposition of leaf litter, as part of regional productivity, produces simple essential nutrients which are used to support the growth of mangroves and organisms in the mangrove ecosystem. Leaf litter as the main component is also a source of carbohydrates and proteins as well as nutrient elements needed for vegetation growth in coastal environments. Community service will be carried out from August to November 2024. The aim of this service is to increase the interest of coastal communities in planting mangroves. This research used litter bags made of nylon, Avicennia marina leaf litter, the fungus Aspergillus sp 1. and milkfish seeds. Collecting bags containing leaf litter that has been applied with the Aspergillus sp 1. fungus is carried out every 15 days. At this time, the weight of the milkfish was also measured up to 6 times. This research found that the weight of milkfish in mangrove litter treated with Aspergillus sp 1. fungus was greater than that of milkfish which was used as a control.
