Abstract

The composite material made is a sandwich composite, GRC-mortar. This system is composed of a combination of laminae with others through a wiremesh that binds Styrofoam. This composite system is used as an earthquake-resistant house wall, which is expected to be not only lightweight, but also rigid and strong, the mechanical testing involved is bending testing to determine the bending strength and modulus of elasticity of the variation in mortar massa of 20 kg, 30 kg and 40 kg. the highest bending strength is 0.88 Mpa given massa mortar 20 kg, the lowest bending value is given over a mass of 30 kg, which is 0.79 MPa. The highest modulus of elasticity is 30 kg of mortar mass, which is 0.005 MPa, while the massa of 20 kg and 40 kg of mortar has a modulus of elasticity value of 0.003 MPa respectively. The composite that provides optimal strength is at a mass of 20 kg, in addition to being quite resistant to high bending strength.

Abstract

The community needs education to change from the first behavior which usually un-separates waste to separate the organic types into non-organic types, even needs developing to have a 3R behavior, reduce, reuse and recycle. Educational activities for the community of the RT 29 RW 08, the village Sawah Lebar Baru were begun with socialization and distributing brochures. In the following week, a questionnaire was distributed to assess who had a better perception of waste among them to be collected and formed into a group. This group was directed to develop their perception into behavior; they were given a means of separating organic and non-organic waste. In the upcoming activity program, an assessment will be carried out on them to find out which ones give more time voluntarily to manage waste. Those who do so will be developed into compost producers or craftsmen of valuable objects from waste
