    As a company that leads the generation of word class services, Indonesia Power has a vision to become a public company with world-class performance and environmentally friendly. To fulfill that vision, Grati Combined Cycle Power Plant (CCPP) contributes to Environmental Compliance (PROPER) Awards by Ministry of Environment of Indonesia. One of assessment criteria of PROPER is assessment of biodiversity protection with reporting aspects that require the presence of data, system information and publishing system that can collect and evaluate status and trends of biodiversity resources, managed at least 2 years. This innovation can increase biodiversity score up to 40 points over 100 of total score. Previously, in Grati CCPP, biodiversity data is manually recapitulated by the Division of Chemical and Environmental using basic Excel application. It causes some problem of difficulties, such as less structured and uneasy to find data due to offline system. We consider that creating application of E-Bios in order to process, evaluate, and present data in an online publication. In addition to better data integrity, E-Bios allows for publication of biodiversity data online as a solution to support Grati CCPP biodiversity innovation.

    In 2013, average waste water production of Grati Combined Cycle Power Plant is about 3,801 m3/month within only less than 8% (eight percent) has been reused for reboisation. It requires more effort to recycle effluent of Waste Water Treatment Plant (WWTP) in order to fullfil water conservation program and zero waste water of power plant with emphasis on Environmental Compliance (PROPER) Awarded by Ministry of Environment of Indonesia. Installation of Brackish Water Reverse Osmosis (BWRO) to process effluent of WWTP can remove chemical and physical impurities in order to reach quality specification of raw water for boiler water. A pilot project BWRO can produce 4 ton/hour service water and reduce specific conductivity effluent of WWTP from 500 microS/cm to less than 20 microS/cm. We also calculate financial analysis from this innovation, which resulted surplus is about IDR 320,060,578/annum from monthly batch BWRO operation of 160 m3 within 5 years payback period. There is also non-financial benefit, connected to improvement of environmental management to achieve higher level of PROPER Award. Potential water conservation from this innovation is 1,600 m3/month or 50% from total waste water by built effluent of WWTP storage pond capacity 300 m3.
