    BOGOR - The Regional Government of West Java Province has committed to processing urban waste originating from the City of Bogor, Bogor Regency, Depok City and South Tangerang City at the Regional LUNA (Lulut - Nambo) Waste Processing and Final Processing Site (Lulut - Nambo) with cutting-edge technology environment in order to be able to extend the life of the TPPAS and at the same time process waste into resources.

    West Java Governor Ridwan Kamil said the project was planned to have the capacity to process 1,650 tons / day of waste up to a maximum of 1,800 tons / day.

    "Alhamdulillah today, after negotiations and also the final agreement, as of today we can have a sophisticated Ground Breaking waste management, for this large scale in Indonesia with MBT technology," said Governor Ridwan Kamil, at the Ground Breaking Event for Processing and Final Processing Luna Regional Waste (TPPAS) (Lulut - Nambo), in the district Klapanunggal, Kab. Bogor, Friday (12/21/18).

    As a follow-up, the Governor said that the West Java Provincial Government has signed a cooperation agreement with PT Jabar Bersih Lestari (PT. JBL) for the Nambo TPPAS Regional Infrastructure Provision on June 21, 2017 with an investment of USD 46 million.

    PT. JBL itself, is a Business Entity formed by the Consortium of Companies winning the auction of Infrastructure Provision of Waste Processing and Final Processing (TPPAS) from the West Java Provincial Government, together with PT. Jasa Sarana as a Business Entity Owned by West Java Province.

    Based on the Cooperation Agreement, the implementation of development requires the latest of 18 months. Based on this, PT. JBL targets no later than July 2020 to operate and receive waste from the City of Bogor, Bogor Regency, Depok City and South Tangerang City.

    "Today, we are starting a process that will be completed in 18 months so that this facility can be used in July 2020," he said.

    "The Collaborative Project between the West Java Provincial Government and PT JBL in the provision of Luna Regional TPPAS infrastructure is the first project and will be a pioneer in large-scale modern waste processing in Indonesia," added Emil, the Governor's nickname.

    As a partner of the West Java Provincial Government, PT. JBL will carry out waste processing services sent by 4 Regencies / Cities to the Lulut - Nambo Regional TPPAS.

    Then, PT. JBL will process the waste to become coal-derived fuel or also called Refuse Derived Fuel (RDF) as an alternative fuel for coal for cement plants, namely PT Indocement Tunggal Perkasa (PT. ITP).

    Processing waste at the Luna Regional TPPAS will benefit all parties. For the West Java Provincial Government, the implementation of final waste processing and processing at the Nambo Regional TPPAS, will ensure the availability of solid waste management services for the people in the Bogor Regency, Bogor City, Depok City and South Tangerang City.

    "Hopefully this will be a perfect example," for the problem of waste in Indonesia, "he hoped.

    In addition, there will also be savings in landfill investment costs and new landfill management because the waste entering the Nambo Regional TPPAS will be processed first so that it will extend the life of TPPAS.

    And, the achievement of the implementation of Law No. 18 of 2008 concerning Waste Management is to achieve the goal of improving public health and the environment and making waste as a resource.

    For PT. JBL, will get benefits in the form of payment for tipping fees from the West Java Provincial Government and also revenues from RDF sales from PT. ITP, with mutually beneficial prices taking into account the feasibility of the project.

    The advantages for PT. ITP, will obtain alternative fuel (green fuel) that is suitable for the purpose of developing the company's vision and mission as Green Industries. As well as obtaining alternative fuel prices (RDF) at competitive prices with coal.

    Acting Head of West Java Environment Agency Nana Nasuha Djuhri revealed, the presence of the Lulut Nangka TPPAS, is a manifestation of the West Java Provincial Government's concern to assist District / City Governments in regional waste management.

    "The land in Nambo Village, Klapa Nunggal Subdistrict, Bogor Regency was originally intended to deal with Bogor Regency waste. However, along with the need to manage waste from Bogor to Depok, this location was developed to be regional," he said.

    Luna's TPPAS, Nana continued, stood on an area of ??55 hectares, consisting of 15 hectares of land belonging to the Bogor Regency Government, and around 40 hectares were state forest areas under the management of Perhutani Corporation.

    While the President Director of PT. JBL, Doyun Yu, revealed that the technology, the management of waste to be used in this project, uses Mechanical Biological Treatment (MBT) designed to produce RDF and compost.

    He also hopes that this regional waste management project can run smoothly according to the plan.

    "Hopefully everything will go according to the set target," said Doyun.


    Principles of Waste Management

    The principle of waste management with this MBT technology has biological and jaw. In the initial stage, garbage trucks that transport urban waste (Municipal Solid Waste-MSW) originating from the City of Bogor, Bogor Regency and Depok City will be weighed first at the weighbridge. This is to record the volume of waste that will enter the processing facility.

    After weighing, the waste will be lowered in the waste receiving area at the Early Stage Processing Building. The average waste entering this facility is 1,660 tons / day with a moisture content of 59.46% and gross calorific value of 1678 kcal / kg.

    At this stage, the garbage will be transported using a wheel loader to then be inserted into the shredder or shredder. Then the enumerated waste will be sent to the Pre Treatment System using a conveyor. While the leachate liquid from the waste in the waste receiving area will be flowed through the leachate channel to be processed later.

    Furthermore, in broad outline, there are four main systems in processing waste with this MBT system, namely, first, Waste Recycling, namely the Pre Treatment System, which is garbage sorted manually to separate or extract a portion of inorganic waste that can be recycle. Then some of the other waste will be chopped to be reduced in size.

    Second, the garbage drying system (Bio Drying), is a process to reduce water content in waste for + 3 weeks. Third, the Post-Treatment and RDF Production Systems are based on the criteria of RDF users, namely PT Indocement Tunggal Prakarsa.

    Fourth, namely controlling the impact of the environment through recirculating leachate (waste water) into biodrying which aims to accelerate the evaporation and drying process of waste. This recirculation system is also expected to prevent contamination of water bodies around the processing site.

    Waste management with this technology will produce RDF as much as 35% of the treated waste and a maximum of 10% in the form of unburnt residual waste such as soil, sand, gravel (stockpiled in sanitary landfills) recycled metal waste and the rest in the form of water evaporating into the air .
