Abstract

Companies engaged in the fabrication sector need a conveyor to move the c purlin from the forming machine to the packaging process. Seeing from these problems, a conveyor design will be carried out. The calculation of machine elements will be carried out to determine the performance of the conveyor and in order to get a good conveyor design. This conveyor has a capacity of 27 tons / day and is large from the rotation of the belt itself, which is 72 rpm. With a speed of 0.38 m/s this conveyor requires an electric motor or ac motor of 0.34 kw or 0.46 hp. This conveyor uses a PVC conveyor belt made of polyester material with a width of 200 mm, a thickness of 3 mm, and there are 2 layers. The total length of this conveyor belt is 17 m. The total weight of this conveyor belt is 44.88 kg and the weight per meter is 2.64 kg. There are four stress points that occur on the conveyor belt, namely 58.64 kg, 89.79 kg, 96.075 kg, 119 kg. The effective stress on the belt is 62.17 kg. Torque is 2248.45 Nm and has a minimum diameter of 9 mm. On this conveyor using bearings UCFL 204/H. The axial force on the bearing is 524.8 N and the radial force is 299.8 N. The transmission system on the conveyor uses a gearbox with a ratio of 1:20.

Abstract

Logistics plays an important role in commerce business and MSME (micro small and Medium Enterprises). Therefore we need a vehicle that helps in the transportation process of products to improve distribution. The vehicle is designed based on the needs of MSME which in general the vehicle will be operated on small urban and rural roads, so the design will consider the dimensions of the vehicle. Author uses Ulrich Method on the process of vehicle design. The Ulrich method is used because it can facilitate the process of product development that suits the target market. In this research, design and manufacture of chassis and supporting components for vehicle drive systems will be carried out. The structural analysis is using the Finite Element Method. In the design and analysis process, the author is assisted with Autodesk Fusion 360 Software. Based on the design, a minimalist three-wheeled scooter has a main dimension of 2227.3mm x 940mm x 967.2mm. After analyzing using the Finite Element Method on a chassis with vertical loading, it was found that the maximum stress is 73.83 MPa with value of safety facor is 3,38. Total production cost of the vehicle is twelve million six hundred and forty thousand rupiah

Abstract

The potential of the sea in Indonesia is commonly used for the utilization of renewable energy from sea waves. One of the efforts to utilize energy, among others, is using a power plant by utilizing seawater wave power energy. So there is a need for ideas and design concepts about mechanical transmission of power plants powered by more effective seawater waves. This study aims to analyze the design of a cylindrical float type Marine Wave Power Plant (PLTG). This discussion focuses on variations in the height of a device, arm length, and buoy diameter. Where when the amplitude and frequency of water waves provide up and down movements of the cylindrical buoy. Then the torque will be generated from the main shaft which has a one way bearing which aims to rotate in the same direction, then forwarded to rotate the generator which will produce electrical energy. The largest power value is obtained in the variation of tool height (Y = 0.5 m), arm length (Pl = 3 meters), and diameter (ø = 0.4 m) which is 599.596 watts. Then the smallest power value in the variation of tool height (Y = 1.5 m), arm length (Pl = 2 m) and buoy diameter (ø = 0.6 m) which is 291.334 watts.
