Abstract

Snakehead (Channa sp.) was one of the superior freshwater fish species native to Indonesia that has been successfully domesticated. The increasing demand for snakehead fish on the market has resulted in the addition of cultivated land and water use. Aquaponics technology was a combination of fish farming and plants that grow without soil media. The aim of this research was to determine the best composition of probiotics that can be used in aquaponic technology to optimize growth rate and feed conversion of snakehead fish (Channa sp.). This research used an experimental method. The experimental design used was a completely randomized design with four probiotic combination treatments and each treatment was repeated three times. The results showed that awarding of different probiotic compositions in the aquaponic system resulted in a spesific growth rate that was not significantly (P>0.05) different between treatments. The highest value of spesific growth rate were in the treatment of probiotic composition of Lactobacillus casei and Saccharomyces cerevisiae with a value of 4.11%/ day. Awarding of different probiotic compositions in the aquaponic system results in significantly (P<0.05) different feed conversion ratio values. The best feed conversion ratio values were in the treatment of probiotic composition of Lactobacillus casei and Saccharomyces cerevisiae with a value of 1.78. The conclusion of this study was the composition of probiotic Lactobacillus casei and Saccharomyces cerevisiae was the best probiotic composition to increase the spesific growth rate and feed conversion ratio of snakehead fish.

Abstract

Tujuan penelitian ini adalah untuk mengetahui kelayakan media PKMD (pengembangan konsep matematika dasar) terhadap perkembangan anak usia dini 4-5 tahun di PAUD kb Laksamana Desa Bukit Batu Kecamatan Bukit Batu Kabupaten Bengkalis . Jenis penelitian ini adalah penelitian dan pengembangan (research and development) yaitu metode penelitian yang digunakan untuk menghasilkan produk tertentu, dan menguji keaktifan media tersebut . Kelayakan produk ini dapat di peroleh dari data materi dan media dan uji coba terbatas pada anak usia 4-5 tahun. produk yang dikembangkan divalidasi oleh 2 ahli media dan materi. Dari hasil validator dapat hasil pada hasil validator mengenai penilaian media jumlah keseluruhan validator 1 dan 2 didapat jumlah persentase 92% dengan kategori “layak”. Dengan adanya penilaian validator 1 dan 2 mengenai produk maka media boleh di uji coba di lapangan. Berdasarkan hasil validator mengenai penilaian materi 1 dan 2 didapat jumlah persentase 91% dengan kategori “layak”. Berdasarkan dari hasil ahli pendidik media maka didapatkan pada ahli pendidik 5 orang didapatkan jumlah skor 75% dengan kategori “cukup layak” . untuk persentase keseluruhan didapatkan jumlah skor 85% dengan kategori “ layak ” untuk ahli pendidik sangat banyak memberikan masukan dan saran yang bertujuan untuk memberikan ciri khas di dalam media sehingga memenuhi unsur media dan mudah digunakan karena adanya petunjuk penggunaan.
