Optimization Design for Manufacturing and Assembly Method in Multifeedstock Jember Biodiesel Processor

Abstract

A method used to optimize the design process in a manufacturing system is the Design For Manufacturing and Assembly Method (DFMAM). The idea of this optimization method is to minimize assembly process errors, reduce redundancy of components, save on production costs, as well as ease of operation. In this study, the method will be used on a biodiesel processor with multi feedstock type equipped with intelligent system for production perimeter control that is specifically designed to produce biodiesel from corn and coconut oil as raw materials produced by Jember, Indonesia. The design framework is made suitable for small-scale biodiesel production in MSMEs for industrial or laboratory purposes, in order to produce biodiesel that meets the biodiesel standards of Ministry of Energy and Mineral Resources of Republic of Indonesia. Processor component assembly via the DFMAM principle is simplified to reduce component complexity and redundancy. The biodiesel produced by this method has been tested and recorded a density value of 15 cel.deg. 874 - 877 kg/m3, viscosity at 40 cel.deg 4.3 – 4.7 mm2/s, Acid value 0.14 0.15 mg KOH/g, Cetane 56 – 58, Cloud Point 7 – 8 cel.deg., pour point 4 – 5, Flashpoint 171 – 178 cel.deg and distillation point 345 – 350 cel.deg.
