Abstract

The creation of a soil-loosening device that works well on dry terrain is the goal of this study. With this equipment, perhaps, human labor in construction and agriculture will be reduced and productivity will rise. In the machine assembly process, virtual assembly is carried out using Autodesk Fusion 360 software prior to the actual assembly phase. During assembly, the mounting frame for the combustion engine is joined to the main frame. Furthermore, sprockets are mounted on the two axles and wheels, and belt tensioners are added. This machine's blade is used to swiftly loosen the dirt. An area of thirty square meters was tested by machines on dry land, and each test took an average of 229.3 seconds to complete. The machine's time efficiency is greater than that of the earlier variants. In addition, factors including longevity, running costs, simplicity of maintenance, and environmental effect need to be carefully considered in this study. This development tool has a great deal of potential to improve the efficiency and productivity of the dry land soil loosening process. The research findings are expected to contribute to technological advancements in Indonesia's building and agriculture sectors.

Abstract

The aim of this research is to modify the coffee bean husking machine to enhance the quality and efficiency of the husking process. The modifications include the addition of a spring mechanism in the grinding space, enabling the outer roller to move flexibly in accordance with the size of the entering coffee beans. Furthermore, these changes also consider reducing the percentage of broken coffee beans during the husking process. The machine underwent two rounds of testing, with three samples tested under two different drying conditions. The research results demonstrate the success of the modifications in achieving their objectives. The machine's capability to husk coffee beans up to the parchment layer, not just the husk, indicates an improvement in the quality of the husking process. The quantity of successfully husked coffee beans also increased, while the percentage of broken beans decreased. By enhancing the quality and quantity of coffee beans produced by this machine, the modifications can significantly benefit coffee farmers. Additionally, this study utilized Autodesk Fusion 360 software to enable virtual assembly of machine components before physical production. The outcomes of the virtual assembly aided in understanding the machine's functionality and the interactions among its components. Therefore, the modifications to the coffee bean husking machine have assisted coffee farmers in producing higher-quality beans and expediting the coffee processing process.

Abstract

This research explores the evolution of technology in pineapple peeling, from the use of manual knives to sophisticated pneumatic technology. The main focus is on pineapple peeling machine design, working principles, and calculating time efficiency between machine and manual peeling. The aim is to broaden students' understanding of designing machines and provide guidance for students in applying pneumatic technology. The study began with literature observations and field studies to collect price and specification data as well as information components about pineapple. Next, planning, manufacturing, and testing of the machine are carried out. Data was collected from both stripping processes for further analysis. The research results include machine designs with main components such as actuators, knife blades, knife fasteners, and machine frames, as well as pneumatic component specifications, which are explained in detail. A comparison of stripping times shows a significant increase in efficiency with the machine, with the fastest time of 9.09 seconds and the longest time of 447 seconds for manual stripping. This research contributes to the development of pineapple processing technology and increases efficiency in the fruit processing industry as a whole.
