Abstract

The Tondano watershed is a very important natural resource and has a strategic function for the surrounding area up to the city of Manado. However, lately there are many problems that occur in the Tondano watershed. The activity of community partnership program for the PKK group of women in the Pinaesaan Kelurahan is carried out, to refresh the knowledge of the existence and sustainability of the Tondano watershed and to recycle the 2 L plastic bottle waste for simple aquaponic activities.Keyword: Tondano Watershed, plastic waste, sustainability, PKK groupABSTRAKDaerah aliran sungai (DAS) Tondano merupakan sumberdaya alam yang sangat penting dan memiliki fungsi strategis bagi daerah sekitarnya sampai ke kota Manado.  Namun demikian, akhir-akhir ini terdapat banyak permasalahan yang terjadi di DAS Tondano. Kegiatan program kemitraan masyarakat bagi kelompok ibu PKK di Kelurahan Pinaesaan dilakukan untuk penyegaran kembali tentang eksistensi dan keberlanjutan DAS Tondano serta mendaur ulang limbah botol plastik kemasan 2 L untuk kegiatan akuaponik

Abstract

Benthic fauna is a group of benthic organisms that live on the bottom of the water or bottom of sedimentary grounds or among sediments. This study aims to understand the distribution and types of benthic faunal organisms measuring > 1mm in the Sario river at a depth of 1-3 m. Benthos sampling was carried out using a grab sampler with three repetitions. The benthic sediment sample was sieved using a 1000 m (1.0 mm) sieve. The sediment retained in the sieve was identified based on its morphological characters using a stereomicroscope. Furthermore, the number of organisms found was counted and analyzed according to the calculation of the ecological index. The results of the identification of benthic faunal organisms >1mm got a total of 60 individuals from 9 families earning an average density of 222.1 ind/m2, Diversity Index 1.04 (medium category), Uniformity Index 0.47 (medium category), and Dominance Index 0.44 (no one dominates). Keywords: Benthic Fauna, Sario River, Density, Ecological Index Abstrak Fauna bentos merupakan kelompok organisme bentos yang hidup di dasar perairan atau dasar sedimen maupun di antara sedimen. Penelitian ini bertujuan untuk mendapatkan gambaran distribusi dan jenis organisme fauna bentos yang berukuran > 1mm di daerah muara sungai Sario pada kedalaman 1-3 m. Pengambilan sampel bentos dilakukan dengan menggunakan grab sampler dengan pengulangan sebanyak tiga kali. Sampel sedimen bentos diayak menggunakan saringan 1000 µm (1,0 mm). Sedimen yang tertahan di saringan kemudian diidentifikasi berdasarkan karakter morfologi dengan menggunakan bantuan mikroskop stereo. Selanjutnya jumlah organisme yang ditemukan dihitung dan dianalisis menurut perhitungan indeks ekologi. Hasil identifikasi organisme fauna bentos >1mm mendapatkan total 60 individu dari 9 famili mendapatkan hasil rata-rata kepadatan 222,1 ind/m2, Indeks Keanekaragaman 1,04 (kategori sedang), Indeks Keseragaman 0,47 (kategori sedang) dan Indeks Dominansi 0,44 (tergolong tidak ada yang mendominasi).
