Abstract

Ketersediaan tandan kosong kelapa sawit (TKKS) di Indonesia belum sepenuhnya dimanfaatkan secara optimal. Salah satu potensi produk yang bisa dihasilkan adalah pulp. Pulp adalah bahan utama dalam produksi industri kertas. Pada proses produksi pulp dengan metode kraft, serat dari TKKS melalui lima tahapan utama yaitu pre-treatment, pulping, washing, liquor separation, dan drying. Tahap pertama dilakukan pre-treatment untuk memproses bahan baku TKKS menjadi serat-serat kecil yang dapat diolah. Selanjutnya, campuran antara natrium hidroksida dan natrium sulfida (white liquor) dimasukkan ke dalam digester yang berisi serat hasil pre-treatment. Proses washing kemudian dilakukan menggunakan air sebelum dilakukan liquor separation, Pulp yang masih berisi liquor berisi lignin (black liquor) dipisahkan pada proses liquor separation agar bisa diproses untuk digunakan kembali. Pulp kemudian dikeringkan pada proses drying, sebelum dimasukkan ke storage. Perencanaan Pembangunan Pabrik pulp dari TKKS ini ingin didirikan di Kawasan Industri Dumai, Provinsi Riau. Kawasan tersebut dipilih dikarenakan ketersediaan bahan baku (Limbah TKKS) yang amat melimpah di daerah tersebut, ketersediaan air melimpah, sumber energi listrik yang memadai, jumlah tenaga
kerja pada usia kerja telah memenuhi, iklim dan topografi yang mendukung untuk perkebunan sawit, dan hukum yang memadai jika dibangun pabrik di daerah tersebut. Adapun, dari hasil analisa perhitungan ekonomi didapatkan IRR 33%, POT 3,5 tahun, dan BEP 51%. Jika dilihat secara keseluruhan, rata-rata %IRR, BEP dan POT masih menunjukkan bahwa pabrik pulp dari tandan kosong kelapa sawit menggunakan metode kraft ini layak untuk didirikan.
============================================================
The availability of oil palm empty fruit bunches (EFB) in Indonesia has not yet been fully optimally utilized. One of the potential products that can be produced is pulp. Pulp is the main ingredient in the production of the paper industry. In the pulp production process with the kraft method, fibers from TKKS go through five main stages, namely pre-treatment, pulping, washing, liquor separation, and drying. The first stage is pre-treatment to process the raw material into small fibers that can be processed. Next, a mixture of sodium hydroxide and sodium sulfide (white liquor) is put into the digester containing the pre-treated fibers. The washing process is then carried out using water before liquor separation, Pulp that still contains liquor containing lignin (black liquor) is separated in the liquor separation process so that it can be processed for reuse. Pulp is then dried in the drying process, before being put into storage. The planned pulp mill from TKKS is to be established in the Dumai Industrial Estate, Riau Province. The area was chosen due to the availability of raw materials (TKKS waste) which is very abundant in the area, abundant water availability, adequate electrical energy sources, the number of workers at working age has met, climate and topography are favorable for oil palm plantations, and adequate laws if a factory is built in the area. Meanwhile, from the results of the economic calculation analysis, the IRR is 33%, POT is 3 years and BEP of 52%. Overall, the average %IRR, BEP and POT still indicate that a pulp mill from oil palm empty fruit bunches using the kraft method is feasible.
