The study mixed coal bottom ash with biomass from municipalities solid waste (MSW), called bio-coal fuel. This study aims to conduct an economic assessment of pilot-scale projects to reuse bottom ash to support the clean industry strategy. LB3 management becomes an obligation for the industry which producing it and being a burden in itself due to the project of waste utilization often regarded as the high-cost investment projects or less profitable. While in the Intensive care system with the average tenure of 385 ducks provides the advantage of Rp 86,428,625,-for one cycle peroduksi or Rp 28,809,541,-per year or Rp 2,400,795,-per month.Coal bottom ash was included in Hazardous and Toxic Waste (LB3), which requires seriously manage not to warm the environment and humans health. In general, each system provides the advantage that the maintenance of the system maintenance Extensive varied with the number of duck ownership average of 65 ducks gives a profit of Rp 3.065.000,-during the production cycle or per year or Rp 255.416,- Semi-Intensive maintenance system with a number of The average tenure of 132 ducks Rp 26.4655.000,-benefit, for one production cycle or Rp 8,812,833,-per year or Rp 735 152,-per month.
Payback Period for each indicator was 25.5 months, 18.82 months and 17.73 months. For the indicator BEP production volume of each grain produces 30 645: 67 980 206 512 grains and, while the indicator for each BEP production rates are Rp 914,- Rp 859,-and Rp 840,.
The results showed that there are three systems maintenance Extensive, Semi Intensive and Intensive each gave a B / C 1.28 1.35 and 1.38. With profit and loss analysis and the feasibility of covering the Benefit Cost Ratio, Break Even Point The volume of business and production rates, Payback Period and the Rate of Investment. Revenue from the sale of duck eggs as a consumer, expired ducks (itik apkhir) and duck droppings as manure. Analysis of the data used is descriptive, which covers a large number of investments, fixed costs, variable costs of each system maintenance duck.
The purpose of this study was to determine how much profit is obtained. Sampling was done randomly from a population and used the questionnaire as a data collection tool, which included the primary data, namely the identity of the breeder, duck maintenance management, business receipts of duck, duck business expenses and capital invested in the duck business. Respondents are made of duck breeders as a Farm, which involves a number of 40 respondents duck breeders producing eggs with a variety of system maintenance.
