Abstract

Penelitian bertujuan untuk mengetahui pertumbuhan fodder millet (Panicum miliaceum) dari pengaruh densitas biji tanam, intensitas cahaya dan umur panen yang berbeda. Biji tanaman yang digunakan adalah pearl millet, ditanam secara hidroponik pada fase fodder. Penelitian menggunakan metode rancangan acak lengkap faktorial 2x3x4 dengan 4 ulangan. Faktor pertama adalah densitas biji tanam 1,5 dan 2,5 kg/m2. Faktor kedua adalah umur panen 6, 9, dan 12 hari. Faktor ketiga adalah intensitas cahaya 25, 50, 75, dan 100% terhadap cahaya penuh. Variabel pertumbuhan yang diamati meliputi panjang daun, tinggi tanaman, produksi biomassa, konversi segar dan konversi bahan kering (BK). Data dianalisa menggunakan anova dan uji lanjut menggunakan Duncan’s Multiple Range Test. Hasil penelitian menunjukkan adanya interaksi perlakuan densitas biji tanam, intensitas cahaya dan umur panen terhadap variabel pertumbuhan fodder. Densitas 2,5 kg/m2 menghasilkan produksi BK lebih tinggi daripada densitas 1,5 kg/m2.Panjang daun, tinggi tanaman, produksi segar dan produksi BK secara nyata (P<0,05) meningkat seiring dengan umur pemanenan 12 hari. Fodder millet perlakuan intensitas cahaya 50% menghasilkan produksi biomassa dan konversi lebih tinggi (P<0,05) daripada intensitas cahaya 25 dan 100%. Penelitian disimpulkan bahwa hasil pertumbuhan dan produksi biomassa fodder millet terbaik pada kombinasi densitas tanam 2,5 kg/m2, intensitas cahaya 50%, yang dipanen umur 12 hari.

Abstract

Catfish farming waste contains a lot of organic materials which also contain phytoplankton. One of the organic materials is in the form of dissolved solids / Total Dissolved Solid (TDS). The content of TDS and Phytoplankton can be used as an alternative growth medium for Daphnia sp. Daphnia sp. is a type of cladocera for fish natural food. Catfish culture waste produces different TDS values ​​depending on the cultivation method and the food given to catfish. This study tested catfish culture waste containing different TDS for Daphnia sp. Treatment Media of catfish culture wastewater with 4 treatments of TDS value of 33, 66, 84 and 110 ppm with 3 replications. Daphnia with a density of 20 individuals / L was reared in an aquarium size 60x30x35 cm filled with 50 L of well water with a TDS content of 100 ppm. Treatment of feeding catfish culture wastewater at a dose of 0.5 L per day. Daphnia sp. and 3.5 L of sifon once a week. Water quality tests (DO, pH, temperature, TDS) were carried out every day as secondary data. The results of the analysis of the growth statistical test of Daphnia sp. showed no significant difference. This means that aquaculture wastewater with TDS values ​​of 33 ppm, 66 ppm, 84 ppm, and 110 ppm results in the growth of Daphnia sp. which is just as good. This is because the phytoplankton that grow in wastewater with TDS values ​​of 33, 66, 84, 110 ppm can meet the feed needs of Daphnia sp. during cultivation. From the results of the water quality test the DO and pH values ​​during the study were in good standard conditions for cultivation. The TDS that was observed every day for one week increased this was due to the dissolved solids content of Daphnia sp. The temperature observed during the study fluctuated very large, where at night the temperature was 20 0C while during the day it was 27.5 0C. This drastic temperature fluctuation led to the proliferation of Daphnia sp. not maximal.
