Freshwater Consumption

A case study of water using network of a coal to methanol plant was under taken with an aim to reduce freshwater consumption, and the accumulated water pinch was employed for minimization of freshwater consumption. The problem was identified as a single contaminant, reuse directly problem. The limiting constraint (i.e. COD) was identified based on the investigation of water quality. A nearest neighbor algorithm (NNA) was used to distribute the fresh water and reuse water among each of operations. The results showed that the flow rates of freshwater and wastewater could be decreased by 24.2% and 86.7%, respectively.

Agroforestry Practices

<p>Humans have utilized landscape for  produces a diverse character of the wider area of the watershed. Agroforestry is a land management system in addressing the problems that arise due to changes in land use of soil and water conservation. The aim of the study was to analyze plant diversity in agroforestry practices that have services in the Krueng watershed landscape in Aceh watershed. Develop strategies in the Krueng Aceh DAS agroforestry service. This research was conducted in the upper, middle and downstream of the Krueng Aceh watershed, with a rapid method of Agro-Biodiversity Appraisal and SWOT. The results showed that the composition of the vegetation structure found in the study sites tended to vary with the diversity index of agroforestry that was currently in the upstream and middle of the Krueng Aceh watershed. Based on SWOT analysis, internal scores are 2.45 and external scores are 3.21. Agroforestry practices in the upper stream of Krueng Aceh watershed were dominated by <em>Aleurites moluccana</em>, <em>Areca cathecu</em>, and  <em>Averrhoa bilimbi</em> L  species with the highest INP in the upper stream of Krueng Aceh watershed. Vegetation at the middle stream of Krueng Aceh watershed dominated by <em>Areca cathecu,</em> <em>Lansium domesticum</em> and Musa<em> paradisiaca</em>.  </p>

Design Council

Co-design is a process in which designers and users collaborate as ‘equals’ to develop innovative solutions. Co-design methods are increasingly used by professional designers to facilitate and enable users to co-develop innovative solutions for ‘themselves’. For example, the Design Council is advocating the use of co-design methods to support the development of practical innovative solutions to social problems such as increased cost of elderly care and tackling child poverty. The involvement of users in developing solutions acknowledges that their take up is dependent on the ways users create and negotiate meanings of objects and services.
