Quantum Teknika : Jurnal Teknik Mesin Terapan or Quantum Teknika is a peer-reviewed journal published by Universitas Muhammadiyah Yogyakarta. Quantum Teknika journal publishes twice a year in April and October. Mechanical engineering is a branch of engineering focusing on mechanical engineering research. Despite of that, the development of the mechanical engineering does not solely encompass machinery science but also other machine-related field such as the automotive science which is composed of energy conversion, design and the forming materials. Quantum Teknika journal accommodates these fields in order to spark various innovations in Indonesia. In the journal Quantum Teknika, accommodate these fields in this period, the year of innovation began in Indonesia. - Automotive Research - Research in The Field of Energy Conversion - Materials Engineering - Design and Manufacture

Abstract

Blade design and material selection for savonius turbines need to accurate to produce high power input. This research aims to make the most robust blade material by vacuum infusion manufactured. The hybrid laminate composite applied in the manufacture of Savonius turbine blades consists of woven carbon fiber with chopped strand mat glass fiber and woven glass fiber. The variations of fiber composition comprised of five layers, namely 5An (5 layers of woven glass fiber), 5Ac (5 layers of chopped strand mat glass fiber), 2C-3An (2 woven carbon fiber-3 woven glass), and 2C-3Ac (2 woven carbon fiber-3 chopped strand mat glass fiber). The results showed 2C-3An for the best variation of hybrid laminate composite with the tensile strength of 219 MPa, with the modulus of elasticity of 6.8 GPa and the smallest density was 1.21 g/cm3.

Abstract

Surface grinding is the finishing proses needs high smoothness and precision. The main demands from this process is precise, roughness, and not burnt. This analyze is made to know the most influential variable for roughness and precision of a product. This analysis is also carried out to determine roughness and precision that can be achieved using the Okamoto Grind-X ACC84ST machine. Variables that used for this analyze are depth of cut, feeding, and cycle per feed. Every variable has three level. DIN CK-45 material is selected to be specimen because it is usually used by manufacturing and automotive industrial to make a main product. Taguchi method is used to reduce time and amount trial. Experiment replication is done to get more accurate data. The most influential variable for roughness is cycle per feed, while the most influential variable for precision is depth of cut. The roughness that can be achieved using the Okamoto Grind-X ACC84ST machine is in the range of 0,075 μm (N3) to 0,175 μm (N4). Size deviations that occurred in this study ranged from -0,007 mm to 0,005 mm.

Abstract

The home industry business of cassava chips on Jogonalan, Klaten was using the manual tools in the process of slicing raw cassava. The cassava cutting machine was an alternative solution for the businessman to increase productivity in the process of producing cassava chips. This machine functions as a cassava cutting in the raw material for making chips. The purpose of this design is to plan a cassava cutting machine with a safe and efficient construction in its application. The machine design method refers to the Pahl and Beitz concept. The planning and design process into the following main phases: Planning and task clarification, conceptual design, embodiment design, and detail design. Analysis of the motion mechanism and calculation of engine elements were used to determine the power specification and capacity of the machine. The planned capacity of the cassava cutting machine is 80kg/hour with a motor power of 0.25 hp, the final rotation of 210 rpm. The results of the technical analysis on the main part of the cassava cutting show that the power capacity of the electric motor, transmission system and frame construction on the machine was safe.
