Abstract

PT. AGS Medan merupakan pabrik yang bergerak dalam produksi pupuk NPK yang salah satu produknyaadalah formula 12.12.17 dengan komposisi 12% unsur nitrogen, 12% unsur fosfor dan17% unsur kalium. Salah satu tahapan dalam proses pembuatan pupuk NPK yaitu proses pengeringan. Jenis dryer yang digunakan adalah rotary dryer dengan putaran 5 rpm dan kemiringan 20o. Pengering yang digunakan adalah udara panas yang berasal dari pembakaran batu bara jenis bitminious di dalam furnace.Untuk menentukan jumlah batu bara yang dibutuhkan dalam proses pengeringan pupuk NPK sebagai bahan bakar furnace maka diperlukan perhitungan jumlah panas. Pengambilan sampel, analisis kadar air dan suhu serta menghitung panas dengan prinsip neraca massa dilakukan dalam penelitian ini. Berdasarkan perhitungan yang telah dilakukan untuk mengeringkan pupuk NPK dengan kapasitas pupuk NPK 7000 kg/jam dibutuhkan energi sebesar 6136268,402Kkal/jam. Jumlah bahan bakar yang dibutuhkan untuk mengeringkan pupuk NPK adalah sebesar 789,219kg/jam.

Abstract

PT XYZ Belawan has a kernel crushing plant unit that produces Crude Palm Kernel Oil (CPKO) with 700 tons/day capacity. Palm kernel processing is carried out in two pressing stages. The first stage or first press produces oil and cake, while the second stage or second press produces oil and meal. The meal still contains 7-8% of the oil content. This study is aimed to determine the amount of CPKO yield, oil content, and oil losses in a meal during the pressing palm kernel process. The method used was the calculation of the mass balance in each process flow. The mass balance calculation is carried out after collecting the secondary data from the factory, including the analysis of water content, solids, FFA, and oil content. Based on the calculation results, CPKO yield was 48.10% of the average kernel mass rate of 714.7155 tons and met the plant standard of at least 44%. Furthermore, the average yield of oil content from the meal was 7.45% and oil losses were 3.86%.
