Abstract

Population and the intensity of the rice stem borer attack can influence pesticide application. This study aimed to examine the effect of active ingredient formulation of solid and liquid Beauveria bassiana bioinsecticide to control rice stem borer (PBP). The research was conducted in tidal lowland rice cultivation in the Village Mulya Sari Banyuasin Regency, South Sumatra, from Maret 2012 to Juni 2012. Observations of population and intensity of attacks observed directly on the rice clump clump as many as 80 samples per ha. The results showed that the application of liquid and solid bio insecticide with active entomopathogenic fungi material effected on the population, the intensity of PBP larvae attack. The results showed that the application of liquid and solid bio insecticide with entomopathogenic fungi active material in the tidal land effect on the population, the attack intensity of PBP larvae. The results found that in tidal land application of liquid bio insecticide could suppress the population aged 10-40 dap of PBP approximately 75%, and solid and bio insecticide approximately 37.5%. Application of liquid bioinsecticide could suppress population aged 50-80 dap of PBP approximately about 55%, and solid bioinsecticide could suppress larval populations of PBP approximately 40%. Liquid bioinsecticide applications could reduce attack intensity PBP of rice plants aged at 10-40 dap approximately 81.75% and approximately 55.44% for solid bioinsecticide.

Abstract

Feed is a major factor in the business of laying ducks. Approximately 70% of the production is to feed. Therefore, to get optimum benefit, feed must be efficiently formulated. To efficient, feed must be balance, the content of feed nutrients must be in accordance with the needs of livestock, so the remaining nutrients out of feed is a minimum. In addition to efficient, balanced feed can also reduce environmental pollution. Waste produced from farm can be a source of contamination of water or wells, if there is no further waste management. One of the consequences of water pollution by livestock waste nitrogen levels are rising. To simplify and accelerate the balanced feed formulations required a software application. This paper aims to introduce balanced feed formulation based software. Application software consists of three main parts, namely database, data processing and results. Simulations conducted on laying ducks feed on the production period. Two types of feed used in this simulation, namely: regular feed (PB) and balanced feed (PS). Each type of feed is repeated five times. Simulation results with the feed formulation software application show significant difference between PB and PS feed. PS is better than PB. Application of balanced feed formulation can be used to support environmentally friendly farming laying ducks.
