Pengaruh pemberian ekstrak daun karamunting (Melastoma malabatrhicum) pada indukan terhadap jumlah anakan dan sintasan hidup benih ikan cupang (Betta sp)
THE EFFECT OF KARAMUNTING (Melastoma malabatrhicum) LEAF EXTRACT ON BREEDES TOWARD THE NUMBER OF BREEDING AND LIFE SURVIVAL OF BETTA FISH (Betta sp) Abstract Betta fish (Betta sp) is a freshwater ornamental fish that is excellent because of its high economic value, thus encouraging cultivators to cultivate it. To produce the mature Betta fish, efforts are needed to accelerate and improve the reproductive performance of Betta fish. This study aimed to examine the effect of giving karamunting leat ectract (Melastoma malabatrhicum) to brooder on the number of tillers and survival Betta fish. This study used completely randomized design (CRD) which consisted of four treatment three replications. The use of karamunting leaf ectract in this study was treatment A: (Control), treatment B was injections of ectract dose ( 1 g/g BW), treatment C was injection of ectract dose (5 g/g BW) and treatment D was injections of ectract dose (10 g/g BW) the parameters observed include; egg diameters percentage of chicks, sr, water quality measuremeants, the results showed that the use of ectract at a dose of 1 g/g. 5 g/g, 10 g/g indicated a larger egg diameter than te control. The highest number of tillers was obtained in treatment B (10 g/g BW) with a total of 37.28% the survival rate of Betta fish from treatment A, B and C had value above 95%. While treatment D there was a total death on the third day. Giving karamunting leaf ectract gave a higher value on the size of the egg diameter. the percentage of the number of tillers. And the SR value Betta fish seeds. Keywords : ectract, Karamuntinng, seeds, Betta, egg
