Abstract

The usage of Azolla Microphylla as fish feed provides several advantages for fish farmers such as; the low-cost, the easy-to-obtain, and the taste that is favoured by some freshwaterfish especially catfish (Clarias Batrachus). Azolla Microphylla is known as one ofPterideophyte aquatic plants that can be utilized as fish feed for catfish because of its highnutritional values, including N, P, Si, Ca, Fe, Mg, and some others. This study aims to analyzethe effectiveness of feeding Azolla Microphylla on catfish length and weight growth by anexperimental method. A completely randomized design was conducted with 5 treatments and 4repeatabilities using 20 fish farms containing a cluster of catfish with an average size of 5 cm,that regularly fed with Azolla Microphylla. The observation was conducted every 10 daysduring the treatment, with a total number of observations held 4 times in the 40-daystreatment. The result indicated that the treatment in P2, with a 60-gram dosage of AzollaMicrophylla feeding, gives the optimal growth on catfish length and weight compared to othertreatments. Best scores in P2 treatment is found in the fourth observation, where the catfishlength reaches around 28 cm, and the weight reached 100 gram. Based on the single factorANOVA test, the real difference values for each group and treatment which analysed at asignificance level of 0,05, namely FvaluesFtable, indicates a significant effect of AzollaMicrophylla on the catfish growth. The Tukey’s Honest Significant Difference test also showsa significant effect of the Azolla Microphylla feeding on the catfish length and weight growth.Therefore, feeding catfish with 60-gram of Azolla Microphylla creates an effective treatmentto gain catfish length and weight.Keywords: Azolla Microphylla, Feeding, Fish Feed, Catfish Growth

Abstract

Telah dilakukan penelitian dengan judul Identifikasi Makrozoobentos di Kawasan Hutan Mangrove Dusun Monsinget Kajhu Kabupaten Aceh Besar yang dilaksanakan pada tanggal 15 s/d 28 Desember 2018 dengan tujuan untuk mengetahui jenis-jenis makrozoobentos yang terdapat di kawasan hutan mangrove Dusun Monsinget Kajhu Kabupaten Aceh Besar. Penelitian ini menggunakan teknik Index Point Abudance (IPA) sehingga diperoleh 3 stasiun yaitu stasiun I berada pada bagian pinggir hutan mangrove daerah muara sungai, stasiun II pada bagian inti hutan mangrove, dan stasiun III pada bagian pinggir hutan mangrove daerah tambak dengan metode line-transect (transek garis) yang masing-masing stasiun terdapat 3 plot garis pengambilan sampel. Hasil identifikasi ditemukan 12 jenis keanekaragaman makrozoobentos di kawasan hutan mangrove Dusun Monsinget yang tersebar pada 9 plot. Sebanyak 12 jenis Makrozoobentos ini terdiri dari 3 jenis kelas Bivalvia (filum Mollusca), 6 jenis dari kelas Gastrophoda (Filum Mollusca), dan  3 jenis dari kelas Crustaceae (Filum Artrophoda). Hasil Indeks keanekaragaman(H’) pada stasiun I berkisar 1,871, pada stasiun II berkisar 1,700, dan pada stasiun III berkisar 0,901 yang menunjukkan kriteria tinggi.Jumlah makrozoobenthos terbanyak ditemukan yaitu dari kelas Gastrophoda spesies Ceritidea cingulata. Kelimpahan makrozoobentos paling banyak ditemukan di stasiun II yang merupakan daerah inti hutan mangrove bersubstrat lumpur dan air tenang karena terkait dengan faktor lingkungan yang sesuai dan bahan makanan yang tersedia. Kata Kunci: Identifikasi, Makrozoobentos, Hutan Mangrove
