Abstract

Snail and rice water has a very high protein content so the snail meat and rice water can be used as an additional food that is good for eel. Giving snail and rice water as a feed supplement in the eel (Monopterus albus) is expected to boost growth in the eel. This study aimed to determine the effect of snails and rice water on the growth of eel (Monopterus albus) and know Where feed to get optimal results on the growth of eel (Monopterus albus). Research conducted at the Laboratory of MIPA IAIN Raden Fatah Palembang. This study used a Rancangan Acak Lengkap (RAL) with 4 treatments and 6 replications. Such treatment is A : pellets 4.5 grams, B : 150 ml of rice water + 3 grams of snail, C : 100 ml rice water + 3.5 grams of snail, D : 50 ml rice water + 4 grams of snail. The analysis showed that the highest growth in treatment D is 50 ml rice water + 4 grams of snail. The conclusion is giving snail and rice water in the eel (Monopterus albus) significant effect on the growth of the body's weight and length of the eel.

Abstract

World Health Organization (WHO) noted that Indonesia was the country with the highest cases of Dengue Hemorrhagic Fever in Southeast Asia. Control efforts include vector observation and monitoring, one of which is larvicides. This study aims to determine the effectiveness of Apu-apu (Pistia stratiotes) leaf extract to inhibit the growth of the third instar larvae of the Aedes aegypti. The design of this study was Completely Randomized Design (CRD). The treatment in this study was repeated 3 times using 4 treatments (negative control treatment, given extract of 10 ml, 30 ml, 50 ml). The results showed that Apu-apu leaf extract had different effects on each test concentration (10ml, 30ml and 50ml). The higher the concentration, the greater mortality of Aedes aegypti larvae. ANOVA test showed that Apu-apu leaf extract (Pistia stratiotes) had an effect with the F=94.667, p= 0,000 on larvae mortality. The ability of Apu-apu leaf extract to kill larvae in LC50 value was 4.0% per minute, analyzed using probit regression. P. stratiotes could be an effective larvicide against A. aegypti third instar larvae (p=0,000).
