Article Integration of Water and Energy Sustainable Program in Cluster Starch Industry

The issue of water supply and sustainable energy is significant in dealing with clean water and energy crises in the long term. In addition, there has been a rise in water and air pollution caused by the community’s activities. Conservation strategies should be implemented to lessen dependence on the supply of clean water and energy and promote self-reliance. The aim of this paper is the existence of a water and energy conservation program system. It is not separately built from the industrial unit, where pollution is a source of raw materials for water and energy to create a sustainable conservation system. The scope of the case report is on the tapioca and sago flour industries. The problem is solved by reusing the wastewater from the production line as raw material for biogas production. The residual water is reused for tapioca and sago starch production. The field data collection was conducted using a combination of primary and secondary data. The case study results are a consistent power supply of 900 kW from a 1.2 MW generator, the reuse of treated wastewater as raw water at a rate of 702 m 3 per day, and an idle capacity of 300 m 3 per day for biogas.
