Abstract

As is known, cement is one of the most important materials needed in infrastructure development. The main equipment for the cement production process is the rotary kiln which is used as a process of burning, mixing and decomposition of the kiln feed which is a mixture of around limestone (70% - 90%), clay (about 10% -30%) , and the rest (0 – 10%) is correction material in the form of iron sand, and silica sand becomes clinker. Specific Fuel Consumption (SFC) is an indicator to determine the performance of the rotary kiln tool, and as an industrial benchmark to save production costs. This calculation is made based on actual data taken from the Central Control Room (CCR) and Quality Control (QC) Laboratory of From the calculation of the mass balance, energy balance, and SFC value, the results for the lowest SFC value were obtained on July 26, 2023, which was 628.77 kcal/kg while the highest SFC value was obtained on July 29, 2023, which was 724.01 kcal/kg. Concluded the SFC is inversely proportional to the number of kiln feeding. The greater the number of kiln feeding, the smaller the SFC value.

Abstract

Metode pengeringan memungkinkan produk tetap berkualitas tinggi untuk waktu yang lebih lama. Salah satu metode alternatif untuk mengeringkan biji kopi adalah dengan menggunakan pengeringan jenis rotary. Rotary dryer merupakan salah satu perangkat yang sering digunakan dalam industri pengeringan yang terdiri dari tabung berputar yang dipanaskan dari luar, dan udara panas diarahkan ke dala m tabung untuk menguapkan kelembaban dari permukaan material yang berputar di dalamnya. Pada penelitian bertujuan untuk mengurangi kadar air pada biji kopi dengan nilai kadar air sesuai dengan standar SNI 01-2907:2008 yaitu sebesar 12,05%. Hasil dari penelitian ini didapatkan kadar air 12,05% pada temperatur 80oC pada waktu selama 300 menit, dengan laju pengeringan paling tinggi sebesar 1,063 kg/jam m2 dengan nilai Specific fuel Consumption (SFC) meningkat hingga 0,383 Kg/kWh.
