Abstract
This study aims to improve the performance of a 25 TPH sterilizer at PT Sampoerna Agro by addressing deformation and shell wall thinning. Pareto analysis identified two major issues—deformation (41%) and wall thinning (24%)—contributing to 65% of operational disruptions. The fishbone diagram revealed root causes including material abrasion, excessive pressure, and high-temperature exposure.The proposed solution involved replacing the bottom screen with ASTM A36 material coated with TCR 4003 and installing TCR 4003 liners on the sterilizer wall. Implementation resulted in increased processing capacity from 33.12 to 35.84 tons/hour, reduced FFB discharge time from 28 to 10 minutes, and improved structural resilience with a safety factor of 3. The solution proved effective in enhancing energy efficiency, reducing downtime, and extending the sterilizer's service life. Keywords: Bottom screen, efficiency, Pareto diagram, Sterilizer, TCR 4003, Penelitian ini bertujuan untuk meningkatkan kinerja sterilizer berkapasitas 25 ton per jam (TPH) di PT Sampoerna Agro melalui perbaikan pada bagian bottom screen yang mengalami deformasi dan shell body yang mengalami penipisan. Berdasarkan analisis Pareto, dua permasalahan ini menyumbang 65% dari total gangguan operasional, yaitu deformasi sebesar 41% dan penipisan dinding sebesar 24%. Analisis fishbone digunakan untuk mengidentifikasi akar penyebab utama, yaitu abrasi material, tekanan berlebih, dan paparan suhu tinggi.Solusi teknis meliputi penggantian bottom screen menggunakan material ASTM A36 yang dilapisi stainless TCR 4003, serta pemasangan liner TCR 4003 pada dinding sterilizer. Implementasi menghasilkan peningkatan kapasitas olah dari 33,12 ton/jam menjadi 35,84 ton/jam, penurunan waktu pengeluaran TBS dari 28 menit menjadi 10 menit, serta peningkatan ketahanan struktural dengan faktor keamanan mencapai 3. Solusi ini terbukti efektif dalam meningkatkan efisiensi energi, mengurangi downtime, dan memperpanjang umur pakai sterilizer. Kata kunci: Bottom screen, efisiensi, diagram Pareto, Sterilizer, TCR 4003,
