Abstract

Organic waste from household can cause air pollution, produces stench. Actually, organic waste can be used to make compost. compost is very useful for fertilizing plants. The purpose of the enlightenment is making compost. The making compost education as an effort to empower low educate communities and optimize the use of organic waste to produce compost. Making compost also can improve skill of communities in Sidomulyo, Babakbowo, Gresik. The long term goal of this extension program is increasing the intelligence and provision of skills to be able to make their own compost and composter. The method that used in the community service program is counseling and assistance in making compost from organic waste. The step of this program began with the socialization and counseling of making compost and composter from household waste. The composter is made by using anaerob composter system. Keywords: Compost, Organic, Anaerob

Abstract

The manufacturing process is an activity of processing raw materials into products to increase added value. One of these products is chair furniture; to reduce errors and failures in its manufacture, it is necessary to do prototype model experiments first. This research conducts a simulation study and analysis of the chair design on stress, deformation and safety factor using the Finite Element Method approach with the help of ANSYS ADPL 18.0 static structural software where the chair design is made of 304 stainless steel, aluminum-T6, HCP 30 polymer foam in one chair structure by simulating several static load loading scenarios, boundary conditions, and even distribution on the surface of the chair. The simulation results show that the highest maximum stress distribution (von misses stress) is 3.5 Mpa at a pressure of 175 kg.f, for the lowest value of 1.5 Mpa at a pressure of 5 Kg.f and a deformation (displacement) of 0.145x10ˉ4 mm occurs at a pressure of 175 Kg.f, while the lowest deformation value of 0.621x10ˉ5 occurs at a pressure of 75 Kg.f, This is due to the loading increasing along with the applied pressure force, but still in the minimum safety factor standard position for static loads, so as not to damage the geometric structure.
