Abstract

Industri pulp dan kertas di Indonesia merupakan salah satu sektor penting dalam perekonomian negara. Industri ini memiliki prospek yang cerah di masa depan dan berpotensi untuk terus berkembang. Hal ini disebabkan oleh peluang pasar yang besar baik di dalam negeri maupun di pasar internasional. Indonesia memiliki potensi dalam menggunakan bahan baku alternatif untuk industri pulp dan kertas berkat keanekaragaman tumbuhan yang ada di negara ini. Salah satu langkah yang diambil adalah mengganti bahan baku kayu dengan bahan baku yang lebih ekonomis, yaitu bagasse atau ampas tebu. Bagasse tersebut akan diolah menjadi pulp melalui proses depithing untuk menghilangkan komponen pith dan menjaga keawetannya selama penyimpanan. Selanjutnya, proses pre-treatment menggunakan Reaktor Steam Explosion dilakukan untuk memisahkan komponen hemiselulosa. Proses delignifikasi dengan penambahan NaOH dilakukan untuk memisahkan komponen lignin dari pulp selulosa. Pulp selulosa kemudian di-bleaching menggunakan larutan H2O2 dan NaOH untuk mendapatkan pulp berkualitas tinggi. Pabrik ini direncanakan memiliki umur selama 10 tahun dengan masa konstruksi selama 5 tahun. Modal tetap pabrik ini sebesar $9.093.386,13 - dan modal kerja sebesar $1.364.007,92. Hasil perhitungan menggunakan metode discounted cashflow menunjukkan nilai Net Present Value (NPV) sebesar $24.366.919, dengan discounted factor sebesar 10%. Laju pengembalian modal (Internal Rate of Return) adalah 49,42% per tahun. Waktu pengembalian modal (Pay Out Time) diperkirakan sekitar 1 tahun 7 bulan. Titik impas (Break Even Point) berada pada 28%.

The pulp and paper industry in Indonesia plays a significant role in the national economy. It has promising prospects for the future and is poised for continuous growth. This is supported by ample market opportunities both domestically and internationally. The diversity of plant species in Indonesia contributes to the potential for alternative raw materials in the pulp and paper industry. One notable initiative is the substitution of wood, the original raw material, with a more cost-effective option: bagasse or sugarcane waste. Before being transformed into pulp, the bagasse undergoes a depithing process to remove the pith component and ensure its longevity during storage. Pre-treatment involves using a Steam Explosion Reactor to separate the hemicellulose components. Delignification is then carried out with the addition of NaOH to separate lignin from cellulose pulp. The cellulose pulp is subsequently bleached using a solution of H2O2 and NaOH to obtain high-quality pulp. The factory is designed to have a lifespan of 10 years, with a construction period of 5 years. It has a fixed capital of $9.093.386,13 and a working capital of $1.364.007,92. By employing the discounted cash flow method, the calculated Net Present Value (NPV) amounts to $24.366.919, with a discounted factor of 10%. The Internal Rate of Return (IRR) stands at 49,42%per year. The payback period (Pay Out Time) is estimated to be 1year and 7 months. The break-even point is at 28%.
