Abstract

Calcium is one of the largest element in the human body with high levels of value of about 1.5-2% of the total body weight. Calcium intake is very important in the process of bone mineralization. Qisthi Hindi has a fairly high calcium content so that its utilization can be maximized for human daily calcium needs. Experiments were performed to determine the calcium content damaged by the drying temperature and to determine the effect of temperature on calcium on root damage Qisthi Hindi. Drying using a Fluidized Bed Dryer with the use of temperatures at 50°C and 100°C during drying based on the results of temperature measurements that can be achieved during the experiment. Levels of increased calcium content at a drying temperature of 50 ° C and the water content was reduced by 5.3% while the drying temperature of 100 ° C the water content is reduced to 52.45%. At a drying temperature of 50 ° C calcium levels increased by 29% from the initial level of the raw material. While the material in the drying temperature of 100 ° C, calcium levels declined from drying at 50 ° C at 15%. Keywords: Dryer, qishti hindi, calcium, fluidized bed dryer Kalsium merupakan salah satu unsur terbanyak dalam tubuh manusia dengan kadar nilai sekitar 1,5-2% dari keseluruhan berat tubuh. Asupan kalsium sangat penting dalam proses mineralisai tulang. Qisthi Hindi memiliki terdapat kandungan kalsium yang cukup tinggi sehingga pemanfaatannya dapat di maksimalkan untuk kebutuhan kalsium harian manusia. Eksperimen dilakukan untuk mengetahui kandungan kalsium yang rusak akibat temperature pengeringan dan untuk mengetahui pengaruh temperature terhadap kerusakan kalsium pada akar Qisthi Hindi. Pengeringan menggunakan alat Fluidized Bed Dryer dengan pengunaan temperature pada bahan 50°C dan 100°C saat pengeringan berdasarkan hasil pengukuran suhu yang dapat dicapai saat eksperimen. Kadar kandungan kalsium meningkat pada temperature pengeringan 50°C dan kadar air berkurang sebanyak 5,3% sedangkan pada temperature pengeringan 100°C kadar air berkurang sampai 52.45%. Pada pengeringan temperature 50°C kadar kalsium meningkat sebesar 29% dari kadar awal bahan mentah. Sedangkan pada temperature pengeringan bahan di 100°C, kadar kalsium menurun dari pengeringan di 50°C sebesar 15%. Kata Kunci: Pengering, qisthi hindi, kandungan kalsium, fluidized bed dryer
