Abstract

Dikenal sebagai salah satu negara yang memiliki kebun kelapa sawit terluas, terbuka peluang besar bagi Indonesia untuk menggunakan potensi sumber daya energi terbarukan untuk menghasilkan energi listrik, terutama untuk daerah-daerah pedesaan atau kawasan terpencil. Limbah kelapa sawit dapat dimanfaatkan sebagai sumber bahan bakar dalam proses gasifikasi untuk menghasilkan syntetic gas (syngas) yang akan digunakan untuk menghasilkan energi listrik. Proses gasifikasi sangat dipengaruhi oleh reaktor gasifier agar gas yang dihasilkan memiliki nilai kalor tinggi dan bersifat mampu bakar. Penelitian ini bertujuan untuk merancang dan membuat reaktor gasifier tipe updraft tanpa blower sehingga tidak memerlukan energi listrik dalam pengoperasiannya, akan tetapi menggunakan daya hisap mesin. Desain ini sesuai untuk pembangkit listrik skala kecil yang tidak terhubung ke jaringan listrik (off-grid) di daerah pedesaan. Berdasarkan perhitungan, ketersediaan energi biomassa diketahui 2113,8 MJ dan hasil rancang bangun gasifier ini diketahui untuk luas penampang reaktor 375 cm2 dan untuk tinggi 100 cm dengan bahan baku 2.47 kg/jam serta menghasilkan daya output dengan kapasitas 5 kW. Penelitian menggunaan genset gasolin dengan output maksimal 2,5 kW. Pada percobaan terakhir, gasifier dioperasikan selama 3 jam dengan menggunakan beban 1 kW menghabiskan arang sebanyak 6.9 kg. percobaan masih perlu diusahakan untuk daya lebih besar dan penggunaan bahan bakar sesedikit mungkin. Kata kunci: Kelapa sawit, gasifier, listrik Known as one of the countries with the largest oil palm plantations, there is a great opportunity for Indonesia to use the potential of renewable energy resources to produce electricity, especially for rural areas or remote areas. Palm oil waste can be used as a fuel source in the gasification process to produce syntetic gas (syngas) which will be used to produce electricity. The gasification process is strongly influenced by the gasifier reactor so that the gas produced has a high heating value and is capable of combustion. This study aims to design and make an updraft type gasifier reactor without a blower so that it does not require electrical energy in its operation, but uses engine suction power. This design is suitable for small scale power plants that are not connected to the electricity network (off-grid) in rural areas. Based on calculations, the availability of biomass energy is known to be 2113.8 MJ and the results of this gasifier design are known for the reactor cross-sectional area of ​​375 cm2 and for a height of 100 cm with a raw material of 2.47 kg / hour and produce an output power with a capacity of 5 kW. The research uses a gasoline generator with a maximum output of 2.5 kW. In the last experiment, the gasifier was operated for 3 hours using a 1 kW load consuming 6.9 kg of charcoal. trials still need to be tried for more power and as little fuel usage as possible.

Abstract

Rokan Hulu is one of the regencies in Riau Province which has an area of ​​about 7747.01 km2 which is divided into 16 (sixteen) districts. One of the problems with the environment is the increase in garbage in the Final Processing Site (TPA) which raises the problem of limited landfill land and the cost of processing waste in the landfill is getting bigger. The waste landfill in Rokan Hulu Regency is located in Tanjung belit Village which has an area of ​​± 2.5 Ha and is 5 km from the residential area. The waste disposed of in this landfill reaches 10-13 (ten to thirteen) tons per day. Until now the collection of sanded waste collection can not be realized effectively due to lack of public awareness of the cleanliness of the environment and on the other hand the location or area of ​​the landfill that is far from Pasir Pengaraian City, and the road or access to the landfill site is still inadequate, besides the limited transportation equipment in the transportation of waste provided by the Environment Agency.
