Strength Analysis of the Frame and Shaft of the Planting Media Mixing Machine With a Maximum Capacity of 100 kg/process
Analisis Kekuatan Rangka Dan Aci Mesin Pembancuh Media Tanam Dengan Kapasiti Maksimum 100 kg/proses
Abstract
Cultivation of white oyster mushroom (Pleurotus ostreatus) is a relatively easy business because the raw materials for planting media are relatively easy to obtain, such as sawdust, rice bran (bran), calcium, and water. The increasing demand for oyster mushrooms is one of the reasons for the development of oyster mushroom cultivation. Mushroom growing media (baglog) can continuously harvest oyster mushrooms within 4-5 months. A mixer is needed to prepare the planting media to save production time. Ensuring the mixing machine can operate for a long time, it is necessary to analyze the strength of the components of the mixing machine, especially against the possible loadings. In this paper, the strength analysis is focused on the components of the engine frame and the mixing engine shaft because the probability of failure is quite large. The strength of the shaft and frame were analyzed using Ansys software. The growing media mixing machine analyzed has a maximum capacity of 100 kg per process, whereas one mixing process takes 12 minutes. The analysis using the Von Misses Stress showed a maximum of 121,8 Mpa on the upper side of the frame and 25.376 Mpa on the shaft for a stirring capacity of 100 kg.
