Abstract

The waste water of tapioca is the waste produced from the washing process raw materials, screening cassava porridge (extraction) and starch sediment containing organic compounds which are still important, especially starch and other compounds that can be used as raw material for the manufacture of bio gas. This study aimed to determine the effect of fermentation time on the elimination percentage of Total Suspended Solid (TSS) using batch anaerobic digester system. Research was carried out by mixing the liquid waste of tapioca industry with water in the ratio 100:0; 85:15; 65:35; 50:50;35:65, and 15:85 (v/v) with starterin an anaerobic digester system batch in which neutral pH of the mixture was set. Parameter observed was the content of Total Suspended Solid. Percentage of elimination of Total Suspended Solid was reached at the rasio of liquid waste to water 100:0 (v/v) with the optimal value of 89.851% on the 21th day.

Abstract

Study about the effect of fermentation time on the percentage removal of chemical oxygen demand (COD) a mixture of tapioca liquid industrial waste and water that aims to determine the effect of water quality and quantity of bio-gas generated from tapioca industrial wastewater combined with water. The research was conducted by combining tapioca industrial wastewater with water on several compositions, namely 100: 0; 85:15; 65:35; 50:50; 35:65; 15:85 (v / v) with cow dung starter in the batch anaerobic digester systems for 24 days with a neutral pH. The optimum percentage of allowance for COD at the ratio of tapioca liquid industrial waste and water at 15:85 with a value of 42.14% where the value of COD on day 0 was 1723 mg / L after day 24 was 997 mg / L .
