Abstract
Rice (Oryzae sativa L.) is one of the main staple food in Indonesia. Given the importance of rice as the main staple food source so any factors that affect the level of production is very important to note. Rice production in the province of Riau year in 2011 – 2012 has decreased production of 53,578 tons to 45,434 tons. One reason is the existence of pest snails, which damages the base of the plant stem. Control efforts undertaken many farmers who use synthetic chemical pesticides, but synthetic pesticides can have negative impacts such as pest resistance, pest resurgence and environmental pollution. Therefore, need another method for controlling snails is to use botanical pesticides are the base ingredients of plant origin that easily obtained as forest betel plant (Piper aduncum L.). This study aims to obtain forest betel leaf starch concentration is good for population control snails (Pomacea sp.) in rice. The experiment was conducted at the Laboratory of the Faculty of Agriculture, University of Agribusiness Incubator County Campus Bina Widya, Pekanbaru which lasted for 3 months (July to September). The data analyzed using a completely randomized design (CRD) with 5 treatments and 4 replicates the SH0 (betel leaf starch concentration woods 0 g/l of water), SH1 (betel leaf starch concentration woods 25 g/l of water), SH2 (concentration forest betel leaf flour 50 g/l of water), SH3 (betel leaf starch concentration woods 75 g/l of water), SH4 (betel leaf starch concentrations forest 100 g/l of water). Application of betel leaf extract powder forests at treatment 100 g/l of water was able to kill the snails pests to 87.50%. Number concentration is still in the range of LC 95 values are from 9.64 to 22.50%. Appropriate concentration to kill 95% of the snails is 16.27% or equivalent 162.7 g/l of water
