Abstract

Industri pulp dan kertas nasional memiliki prospek yang cukup cerah di masa depan, dan berpeluang untuk terus berkembang. Hal ini antara lain didukung oleh prospek permintaan meningkat pada kertas kemasan (packaging). Proses produksi kertas merupakan suatu rangkaian proses yang merubah fibrous feedstocks menjadi pulp. Pada produksi pulp menggunakan metode organosolv terdapat lima tahapan proses yaitu pre-treatment, pulping process, washing and separation, dan ethanol recovery. Proses pertama yaitu pre-treatment dilakukan untuk mereduksi ukuran bahan baku utama yaitu tandan kosong kelapa sawit. Selanjutnya dilakukan proses pulping menggunakan ethanol dalam digester bertekanan 15 atm. Kemudian dilakukan tahap pencucian dan pemisahan slurry pulp dengan filtrat berupa larutan lignin. Lalu pulp akan dikeringkan menggunakan tray dyer sebelum dimasukan pada tangki penampung produk berupa pulp. Pabrik pulp dari TKKS ini didirikan di Kawasan Industri Dumai, Riau. Kawasan tersebut dipilih dikarenakan ketersediaan bahan baku yang amat melimpah di daerah tersebut (luas lahan kelapa sawit terluas di Riau dan terdapat banyak pabrik CPO), ketersediaan air melimpah, sumber energi listrik cukup memadai, jumlah tenaga kerja pada usia kerja memenuhi, dan dilandaskan hukum serta topologi daerah yang memadai jika dibangun pabrik di daerah tersebut. Adapun, dari hasil analisa perhitungan ekonomi didapatkan IRR 18,48%, POT 7 tahun, dan BEP 57,76%. Jika dilihat secara keseluruhan, rata-rata %IRR, BEP dan POT masih menunjukkan bahwa pabrik pulp dari tandan kosong kelapa sawit menggunakan metode organosolv ini layak untuk didirikan.

The national pulp and paper industry has promising prospects for future growth. It is supported by the increasing demand for packaging paper, cardboard, and tissue. The paper production process involves a series of steps that transform fibrous feedstocks into pulp. In the organosolv pulp production method, there are five stages: pre-treatment, pulping process, washing and separation, and ethanol recovery. The first step, pre-treatment, is carried out to reduce the size of the main raw material, which is empty palm fruit bunches. The pulping process is then conducted using ethanol in a pressurized digester at 15 atm. Subsequently, the pulp slurry is washed and separated from the lignin solution through filtration. Afterward, the pulp is dried using a tray dryer and stored in a pulp storage tank. The pulp plant using empty palm fruit bunches (EFB) is established in the Dumai Industrial Zone, Riau. The location is chosen due to the abundant availability of raw materials in the area (the largest oil palm land area in Riau and the presence of many CPO factories), ample water resources, sufficient electricity supply, an adequate workforce in the working age range, and a suitable legal and topographical environment for establishing the plant in the area. The economic analysis results indicate an Internal Rate of Return (IRR) of 18%, Payback Period (POT) of 6 years, and Break Even Point (BEP) of 56%. Overall, the average IRR, BEP, and POT percentages demonstrate that establishing a pulp plant using empty palm fruit bunches and the organosolv method is feasible.
