Abstract

Penelitian ini bertujuan untuk mengetahui komposisi dan keanekaragaman gastropoda yang berasosiasi dengan ekosistem mangrove di wilayah pesisir Teluk Tomini sekitar Desa Tabulo Selatan Kecamatan Mananggu. Penelitian ini dilaksanakan pada Bulan April sampai Bulan Desember 2014. Metode yang digunakan dalam pengambilan data adalah metode line transek dengan menggunakan kuadran berukuran 1x1 meter. Lokasi penelitian dibagi menjadi 3 stasiun yaitu Stasiun I (dekat Pemukiman), Stasiun II (Area Rehabilitasi), dan Stasiun III (dekat Estuary). Semua jenis gastropoda yang terdapat di dalam kuadran (epifauna dan treefauna) dihitung dan diidentifikasi. Parameter kualitas air yang diukur yaitu suhu, pH, salinitas, dan substrat. Analisis data meliputi komposisi jenis, dan keanekaragaman gastropoda. Hasil penelitian menunjukkan bahwa jenis gastropoda yang ditemukan pada lokasi penelitian ada 10 jenis dari 7 famili. Komposisi tertinggi gastropoda treefauna dari spesies Littorina scabra yaitu 39,52%, terendah dimiliki oleh gastropoda epifauna dari spesis Chicoreus capucinus yaitu 1,52% . Indeks keanekaragaman secara rata-rata masuk kategori sedang. Kualitas air dan substrat yang terukur masih dalam kondisi layak untuk kehidupan gastropoda. Kata kunci: Komposisi, keanekaragaman, gastropoda, ekosistem mangrove

Abstract

This study aims to determine the effect of immersion in a mangrove api-api (Avicennia marina) leaf juice with different doses that affect the survival of tilapia (Oreochromis niloticus) seeds infected with the parasite Trichodina sp. This research is a quantitative descriptive study with 4 treatments and 3 replications. The fish used were tilapia that had been infected with an initial intensity of 205 Trichodina sp. This research was conducted for 7 days. The treatment used was the dosage of mangrove leaf juice and water, where the dosages were A (2.5 gram/liter), B (5 gram/liter), C (7.5 gram/liter) and D (Control). The results showed that giving different doses of api-api leaf immersion had an effect on the survival of tilapia where the use of the mangrove leaf juice at a dose of 7.5 mg/liter gave the best survival results with a percentage of 86.66% and also is a solution dose that can reduce the intensity of Trichodina sp. The results of the calculation of the intensity of Trichodina sp. in treatment A (2.5 gram/liter), namely 30 individuals/head and treatment B (5 gram/liter) 15 individuals/head of treatment C (7.5 gram/liter) the intensity of Trichodina sp. 6 individuals/head. Keywords: Mangrove; api-api; Avicennia marina; tilapia; Trichodina sp.; survival rate.

Abstract

This study aims to determine the effectiveness dose of EM4 (Effective Microorganism-4) pro-biotic to increase the population of Daphnia magna natural feed. This study used a completely randomized design (CRD) with three treatments and three replications. The treatment in this study used pro-biotic EM4 with a dose of 1 ml for treatment A, a dose of 3 ml for treatment B. 5 ml dose for treatment C and a dose of 7 ml for treatment D. The highest population growth rate was found in treatment A dose 1 ml. Followed by treatment B with a dose of 3 ml, treatment C at a dose of 5 ml and the lowest at treatment D at a dose of 7 ml with values of 0.29, 0.09, 0.05 and 0.03 respectively. ANOVA analysis showed that the provision of pro-biotic EM4 had an effect on the population growth rate of Daphnia magna. The data from the further test of the least significant difference (LSD) showed that treatment A was significantly different from treatment B, C and D. Treatment B, C and D were not significantly different. The results of water quality measurements for temperatures ranging from 26-29 ° C, pH ranges from 5-6 and Dissolved Oxygen (DO) ranges from 4.4-4.9 mg / liter. This condition is the optimum range in Daphnia magna culture. Keywords: Daphnia magna; EM4 (Effective Microorganisme-4); population increase
