Abstract
Pengaruh suhu pengeringan porang terhadap kadar glukomanan dan oksalat telah diteliti. Variasi pengeringan yang digunakan adalah oven dengan suhu 45, 50, 55, dan 60℃, serta pengeringan dengan matahari. Kadar glukomanan dianalisa dengan metode gravimetri, sedangkan kadar oksalat dianalisa dengan titrasi permanganometri. Analisa glukomanan menghasilkan kadar tertinggi pada suhu 55℃ sebesar 51,62%. Uji ANOVA menunjukkan bahwa suhu pengeringan yang optimum yaitu 55℃ berpengaruh terhadap tingginya kadar glukomanan. Nilai kadar oksalat pada porang menurun seiring menurunnya suhu pengeringan, dengan kadar oksalat terendah diperoleh pada suhu 45℃ sebesar 5,37%. Uji ANOVA menunjukkan adanya pengaruh suhu pengeringan terhadap menurunnya kadar oksalat.

The effect of drying of porang tuber toward glucomannan and oxalate content has been studied. Variation of drying used are oven drying with temperature of 45, 50, 55, and 60℃, and sun drying. Glucomannan content analyzed by gravimetric method, while oxalate content analyzed by permanganometric titration. The results showed that the highest glucomannan content was 51,62% in 55℃. ANOVA analysis shows optimum drying temperature, 55℃, affected the high glucomannan content. The results showed that oxalate content decreased with temperature, which lowest content is 5,37% in 45℃. ANOVA analysis shows drying temperature affected the decrease of oxalate content.
