This study is to determine the effect of sugar content in the sago effluent using filtered and unfiltered sago effluent samples obtained from the sago factory. The samples were stored at different temperature and period of times to observe the effect of sugar content in sago effluent. The sago effluent were characterized according to its starch concentration using iodine test and sugar concentration using Dinitrosalicylic acid (DNS) test. Based on the analysis that have been made, pH ranging of filtered sago effluent has decreased from 5.57 to 4.15 at cold temperature (4°C) and it also decreased from 5.67 to 3.86 at room temperature (25°C) both within 30 days. Then, for the unfiltered sago effluent, it shown a decrease in pH ranging from 4.50 to 3.80 at cold temperature (4°C) and it also decreased from 4.40 to 3.00 at room temperature (25°C) both within 25 days. The highest amount of starch concentration for filtered sago effluent is 37.27 g/L when stored at day 0 for cold temperature (4°C) and 37.91 g/L when stored until day 10 for room temperature (25°C). For the unfiltered sago effluent, the highest amount of starch concentration is 52.40 g/L when it stored until day 10 at cold temperature (4°C) while 54.90 g/L when stored until day 10 for room temperature (25°C). Moreover, the highest glucose concentration for filtered sago effluent is 30.61 g/L when stored until day 15 for cold temperature (4°C) and 27.94 g/L when it stored until day 15 for room temperature (25°C). For unfiltered sago effluent, the highest glucose concentration is 23.13 g/L when stored until at day 0 for cold temperature (4°C) and 20.88 g/L when stored at day 0 for room temperature (25°C). Next, the highest amount of total sugar recovery for the filtered sago effluent is on day 15 at cold temperature (4C). which 90.1% starch converted into sugar while at room temperature (25 ° C), the 74.9% starch converted into sugar on day 5. However, the highest amount of total sugar recovery for the unfiltered sago effluent is on day 5 at cold temperature (4'Q, 47.6 % starch converted into sugar while at room temperature (25'C), 42.4 % starch converted into sugar on day 0. Thus, sago effluent had high potential to become an alternative substrate to sago starch for sugar production.
