Abstract
Pulp adalah hasil pemisahan serat dari bahan baku berserat. Industri pulp dan kertas sangat berkaitan dengan industri lain, di antaranya percetakan, industri pengemasan dan pengepakan, serta penunjang berbagai kegiatan administrasi, perkantoran, dan kearsipan. Konsumsi pulp dan kertas semakin meningkat dari tahun ke tahun. Salah satu bahan pembuatan pulp adalah bagasse. Bagasse merupakan sumber biomassa yang berasal dari limbah pabrik gula. Bagasse mengandung banyak selulosa, hemiselulosa, dan sedikit lignin. Pabrik pulp selulosa dari bagasse ini terdiri dari 3 proses utama, yaitu: pre-treatment, di mana dalam proses ini akan terjadi pemisahan hemiselulosa; delignifikasi untuk menghilangkan lignin; dan bleaching untuk memutihkan pulp agar sesuai dengan SNI. Pabrik ini direncanakan akan berdiri tahun 2022 di Daerah Tlogowaru, Kota Malang, Jawa Timur, dengan kapasitas 33.168.632,45 kg/tahun yang beroperasi secara batch 24 jam/hari selama 330 hari dalam setahun. Produk akhir yang dihasilkan oleh pabrik ini adalah pulp selulosa. Dari analisis ekonomi menggunakan metode discounted cash flow diperoleh nilai Net Present Value (NPV) sebesar Rp309.167.620.350 dengan WACC 8,8%. Laju pengembalian modal (Internal Rate of Return) sebesar 17,60% per tahun. Waktu pengembalian modal (Pay Out Time) adalah 4 tahun 10 bulan. Titik impas (Break Even Point) sebesar 27,70%. Sensitivitas terhadap IRR akan menguntungkan saat harga bahan baku dan modal tetap mengalami penurunan nilai, serta harga jual produk mengalami peningkatan nilai.

Pulp is produced by separating fibers from fibrous raw materials. The pulp and paper industry is closely related to other industries, including printing, packaging, and supporting various administrative, office, and archival activities. The consumption of pulp and paper is increasing from year to year. One of the raw materials used to produce pulp is bagasse. Bagasse is a source of biomass derived from sugar factory waste. Bagasse contains high amounts of cellulose and hemicellulose, as well as a small amount of lignin. The cellulose pulp mill from bagasse consists of three main processes: pre-treatment, in which hemicellulose is separated; delignification, to remove lignin; and bleaching, to whiten the pulp to comply with SNI standards. This plant is planned to be established in 2022 in the Tlogowaru area, Malang City, East Java, with a production capacity of 33,168,632.45 kg/year. The plant will operate in batches for 24 hours/day and 330 days/year. The final product produced by this plant is cellulose pulp. Based on an economic analysis using the discounted cash flow method, the Net Present Value (NPV) is Rp 309,167,620,350 with a WACC of 8.8%. The rate of return on capital (IRR) is 17.6% per year. The Pay Out Time is 4 years and 10 months. The Break Even Point (BEP) is 27.7%. The sensitivity analysis of the IRR indicates that the project becomes more favorable when raw material prices and fixed capital decrease, while the product selling price increases.
