Abstract

The partner in this program is a collaboration with the Mechanical Students Association (HMM) of all universities studying in the Mechanical Engineering study program which is currently completing its final project in Aceh. The partner's problem is the lack of ability to write scientific articles, and, not knowing how to submit scientific articles via OJS (Oper Journal System), and the solution offered is to provide an introduction to strategies for writing scientific articles and the OJS stages in the journal publishing process, provide training in creating author accounts at OJS, providing training on submitting scientific articles through OJS, outreach on how to write scientific articles, as well as training on writing scientific articles. The results of service activities are that partners can recognize OJS and the OJS stages in the journal publishing process, partners have author accounts and can submit scientific articles to OJS, partners can write scientific articles well and correctly. Monitoring and evaluation are also carried out for the sustainability of further activities to resolve partner problems.

Abstract

This paper discusses the process of optimizing the truss structure step by step from 2D to 3D space using finite element analysis. This step-by-step optimization process is carried out to simplify the analysis of truss structures from simple to more complex cases. Optimization aims to obtain the minimum cross-sectional area and weight for each truss member. The stages of the optimization process carried out in this study are starting from a 2-dimensional (2D) truss structure with several two and five members to a 3-dimensional (3D) one-level tower with a total of 18 members. The optimum criterion as the constraint used is the full stress design method and the value of the cross-sectional area and weight of the structure as a result of optimization, leading to convergence during the iteration process. The tool used to run the iteration process is performed using Fortran software. The results of this optimization process are the total cross-sectional area (A) and a minimum of weight (W), that is, for a two-member truss A = 1 in2 and W = 4 lb, for a five-member truss A = 3.48 in2 and W = 14 lb. Furthermore, for a one-level of tower-space truss with a total of 18 elements, A = 57.91 in2 is obtained and the optimum weight of the truss structure is W = 134.02 lb. From these results, it can be seen that the optimization process that starts from simple to complex cases can be carried out easily and still takes into account the existing constraints
