Abstract

The Energy Efficient Car Contest (Kontes Mobil Hemat Energi or KMHE) is a national competition in Indonesia that challenges university students to develop ultra-efficient prototype vehicles. This study presents the design, simulation, and manufacturing of a custom steering system for the Laksamana V 1.0 single-passenger prototype vehicle developed by Team Laksamana. The steering system was engineered to meet strict requirements for weight, structural reliability, ergonomic fit, and maneuverability under competition conditions. A rack-and-pinion mechanism was selected after comparative evaluation of multiple steering concepts. Computer-Aided Design (CAD) and Finite Element Analysis (FEA) were employed to optimize the geometry and assess the mechanical strength of key components, including a tie rod made from SUS 201 stainless steel. The manufactured system weighs 3.74 kg, delivers a steering ratio of 12:1, and requires 2.8 Nm of torque, ensuring both agility and driver comfort. Although the measured turning radius was 6.3 meters—above the original target—it remains functional for KMHE circuits. FEA results confirmed that all structural stresses and deformations were well within safe limits, validating the design’s stiffness and durability. Overall, the developed steering system is reliable, efficient, and suitable for application in energy-efficient vehicle competitions.

Abstract

In terms of potential, the people of Palas Village mostly depend on the agricultural sector, industrial employees and fisheries in the river basin (DAS). One of the local potentials that is quite prominent is the existence of a Fishing Park on the banks of the Siak River (SUSI). With 6 floating houses and 2 fishing boats, it can improve the decent life for partners by seeing changes in their increasingly improving economic growth so that the sustainability of this program can be carried out in such a way. Implementation in the form of intensive implementation and assistance to produce mobile-based floating house empowerment products. The activities that have been carried out are the manufacture of 5 floating houses for a size of 2x2 meters and 1 unit with a size of 3x5 meters, as well as one unit of fiber boat made from new with a 7.5 Hp engine and repair of 1 unit of 20 Hp capacity boat, as well as the installation of a 100Wp solar panel lighting system and financial management and asset management training have also been carried out as well as social media-based marketing training.
