Ecomaterials in Low-Cost Housing. Connecting Cutting-Edge Science with the Grassroots

This research is purposed to formulate model of slum settlement policy in Nusa Tenggara Barat Province. Method used in this study is mixed method with data collection method is Purposive Sampling and Analytical Hierarchy Process (AHP). Study discussion is resulting in alternative policy of settlement policy in Nusa Tenggara Barat Province, Indonesia that is: (1) demolition of slum area; (2) opening job vacancy; (3) providing low-cost housing; (4) providing loans from banks; and (5) flats. From these alternative policies, it is aimed to raise standard of living in Nusa Tenggara Barat province, especially in the area of study and eliminating slums area to achieve the correct urban planning.

Reinforcing Filler

The development of an inter-cross-linked polymer network of thermoset-thermoset blends have been extensively studied due to their enhanced mechanical properties. Among various polymer blends, modifications of unsaturated polyester (UPE) resin with epoxidized soybean oil acrylate (ESOA) combinations are an attractive route to promote the performance of the thermoset matrix and to overcome the inferior properties of both the components. Biodegradable and effectively accessible chitosan biodegradable waste material can shape the new stage for cutting-edge innovation items. Blend of both recyclable fibrous reinforcement and eco-friendly filler with two miscible thermosetting polymers will provide enhanced properties. At this time, chitosan up to 15 wt% (based on matrix weight) was utilized as reinforcing filler. At last, an interesting result was built up by confirming that chitosan filled chemically tailored bamboo and UPE/ESOA (80:20) biocomposites offered enhanced properties by 10 wt% of filler concentration with the most enhancements in whole properties. They have extensive variety of applications in the sector of low cost housing, structural projects and structural laminates.
