Abstract

Peningkatan kebutuhan mikrokrisalina selulosa (MCC) di Indonesia yang belum dapat dipenuhi oleh produksi domestik menjadi latar belakang perancangan pabrik MCC ini. Proyek ini bertujuan untuk merancang pabrik MCC dengan kapasitas produksi 3.500 ton per tahun, menggunakan kayu sengon (Albizia chinensis) sebagai bahan baku utama. Hasil studi menunjukkan bahwa pabrik MCC ini berpotensi mengurangi ketergantungan impor MCC serta membuka peluang ekspor, seiring dengan meningkatnya permintaan MCC dalam industri farmasi, makanan, dan kosmetik. Kayu sengon dipilih karena memiliki kandungan selulosa yang tinggi (≥45%) dan pertumbuhan yang cepat, serta tersebar luas di wilayah Indonesia. Proses produksi MCC melibatkan beberapa tahap utama, yaitu pulping kimiawi metode soda, bleaching secara Totally Chlorine-Free (TCF), hidrolisis asam untuk pembentukan MCC, dan pengeringan menggunakan tray dryer. Pemilihan teknologi dilakukan berdasarkan pertimbangan teknis, ekonomi, dan dampak lingkungan. Lokasi pabrik di Madiun, Jawa Timur dipilih dengan mempertimbangkan akses bahan baku, sarana transportasi, ketersediaan utilitas, pemasaran, iklim, ketersediaan tenaga kerja, dan legalitas. Berdasarkan dengan serangkaian uraian proses yang dilakukan, kayu sengon dengan laju alir 1.039,309 kg/jam dapat menghasilkan 441,921 kg/jam MCC dengan kemurnian 99,875 %. Berdasarkan analisis ekonomi yang telah dilakukan, didapatkan penaksiran model (CAPEX) sebesar Rp 450.152.678.927,58; biaya operasional (OPEX) sebesar Rp 317.701.431.271,59 per tahun. Estimasi umur pabrik adalah 15 tahun. Berdasarkan perhitungan didapatkan nilai IRR sebesar 16,97%; POT selama 5,8 tahun; dengan BEP sebesar 33,69%; dan NPV yang bernilai positif yaitu Rp 231.834.664.106,80. Berdasarkan hasil analisis dan perhitungan ekonomi, pendirian pabrik MCC dengan kapasitas 3.500 ton per tahun layak untuk didirikan.

The increasing demand for microcrystalline cellulose (MCC) in Indonesia, which has not yet been met by domestic production, serves as the background for the design of this MCC plant. This project aims to design an MCC manufacturing plant with a production capacity of 3.500 tons per year, using silk tree (Albizia chinensis) as the primary raw material. The study indicates that this MCC plant has the potential to reduce reliance on MCC imports and create export opportunities, in line with the growing demand for MCC in the pharmaceutical, food, and cosmetics industries. Sengon wood was selected due to its high cellulose content (≥45%), rapid growth rate, and wide availability across Indonesia. The MCC production process involves several key stages, namely chemical pulping using the soda method, Totally Chlorine-Free (TCF) bleaching, acid hydrolysis for MCC formation, and drying using a tray dryer. Technology selection was based on technical, economic, and environmental considerations. The plant location in Madiun, East Java, was chosen by considering access to raw materials, transportation facilities, utility availability, market potential, climate, labor availability, and legal aspects. Based on the outlined process, sengon wood with a flow rate of 1.039,309 kg/hour can yield 441,921 kg/hour of MCC with a purity of 99,875%. The economic analysis estimates a capital expenditure (CAPEX) of IDR 450.152.678.927,58 and an operational expenditure (OPEX) of IDR 317.701.431.271,59 per year. The estimated plant lifespan is 15 years. The economic evaluation results in an internal rate of return (IRR) of 16,97%, (POT) of 5,8 years, a break-even point (BEP) of 33,69%, and a positive net present value (NPV) of IDR 231.834.664.106,80. Based on the analysis and economic calculations, the establishment of an MCC plant with a capacity of 3.500 tons per year is feasible.
