Abstract

Kerusakan hutan mangrove di Desa Silo Baru menyebabkan terganggunya fungsi mangrove baik secara fisik, biologis, dan ekonomi. Upaya rehabilitasi dilakukan sebagai sebuah langkah perbaikan agar fungsi-fungsi tersebut dapat kembali berjalan sebagaimana mestinya. Selain itu, kegiatan rehabilitasi bisa memicu perubahan atau penambahan komposisi dan keanekaragaman jenis di suatu wilayah. Penelitian ini bertujuan untuk mengetahui komposisi dan keanekaragaman jenis vegetasi mangrove hasil rehabilitasi di Desa Silo Baru, Sumatera Utara. Pengambilan data dilakukan pada 4 lokasi rehabilitasi mangrove menggunakan metode transect line plot dengan jarak antar petak ukur adalah 55 m. Setiap petak ukur dilakukan pengamatan vegetasi dengan metode nested sampling menggunakan petak ukur 10x10 m untuk pohon, 5x5 m untuk pancang, dan 2x2 m untuk semai. Analisis dilakukan dengan menggunakan INP dan indeks diversitas Shannon. Hasil menunjukkan bahwa ditemukan 12 jenis vegetasi mangrove yang terdiri dari 10 mangrove mayor dan 2 mangrove minor. Jenis mangrove yang mendominasi pada setiap lokasi rehabilitasi berbeda-beda dan keanekaragaman jenis mangrove hasil rehabilitasi di Desa Silo Baru tergolong kriteria keanekaragaman rendah hingga sedang.

Abstract

Ecotourism development, especially in Central Bangka Island of Ketawai more rapidly. The rapid tourist activities on the Island of Ketawai can cause loss of quality attractions for damage to the ecosystem. This is because the pressure on the environment caused by the increased number of tourists. This study aims to determine the  maximum capacity rating  with ratings of three aspects:  (1) the carrying  capacity  of  the  region  (DDK),  (2)  the  carrying  capacity  of  the environment (the carrying capacity of the physical / PCC and the carrying capacity of the real / RCC), and (3) ecological carrying capacity (AR). This  study  uses  primary  data  by  direct  observation  in  the  field  and secondary data from relevant agencies. An assessment of the carrying capacity of the region (DDK), an assessment of the carrying capacity of the environment using methods the Physical Carrying Capacity (PCC), the carrying capacity of the Real (RCC), and an assessment of the ecological carrying capacity (AR). The  results  obtained,  there  are  two  tourist  activity  on  the  island  of Ketawai are picnic and camping. The result of the carrying capacity of the region (DDK) for picnic activities is 240 people / day and camping activities is 900 people/day. The  results  of the  physical  carrying  capacity (PCC)  for  picnic activities is 249 people / day and for camping is 100 people / day. Assessment of the real carrying capacity (RCC) for picnic activities is 239 people / day and camping 96/day. Ecological carrying capacity assessment. (AR) obtained the results of 81 people / day for a picnic and activity type 43 / day for camping activities. The value of these calculations are still well above the actual number of tourists who currently account for 9 person / day. Attraction Development Ketawai Island can still be optimized however, by taking into account the balance and sustainability of the local environment.
