Abstract

Trolley is a means of moving from one area to another. A very helpful manual tool for moving goods, in order to facilitate the movement of an item to the destination. However, these activities will be hampered if the luggage is a lot and heavy. So the trolley will be made slightly different from the general trolley, namely in the form of a trolley that can be paired as a bicycle holder. This tool has a main frame that can be called for a load, the frame itself uses low carbon steel material in the form of a hollow box, namely St37 steel with a length of 188 mm, width 15x15 mm and thickness of 1.3 mm. In this study, to complete the analysis of frame strength using Solidworks Software, using a static simulation feature so that the stress value that occurs can be known. Solidworks is able to improve and validate performance and reduce the need for prototypes or costly design changes at a later date. The results of this study indicate that the trolley using low carbon steel material with a predetermined size is able to withstand the load of 30 kg.

Abstract

Indonesia as a tropical country has the potential to develop and utilize solar energy as one of the many solar energy conversion systems, this solar energy conversion system can be applied to overcome the depletion of existing conventional fuel reserves. The main objective of this final project is to determine the effect of solar tracker angle on solar panel power on 1 axis and 2 axis solar tracker. The angle of the solar tracker affects the performance of the solar panel, namely the closer it is perpendicular to the arrival of the solar light, the greater the voltage and current. Solar cells that use a tracker are able to absorb solar energy more optimally than those without a tracker. The power absorbed by the 2 axis solar tracker is very large, so this tool has a greater power efficiency than previous technologies.
