Abstract

The curing process or vulcanization process is the final stage of the tire manufacturing process, where the properties of the tire compound change from rubber-plastic material to become elastic by forming cross-links in its molecular structure. The green tire is formed in the curing process, which is placed on the bottom mould. The inside of the green tire surrounds the bladder. The top mould will close to carry out the next curing process. In closing the mould, there is a shaping process of forming a green tire placed on the bladder and given a proportional pressure. Improper or abnormal radius shaping results cause seventy percent of product defects. This paper proposed abnormal detection of radius shaping in the curing process using Fine-tuned Deep Neural Network (DNN). Several DNN models have been examined to analyze an optimized DNN model for abnormal detection of radius shaping in the curing process. The fine-tuned DNN architecture has been exported for the curing system. The DNN was trained with a training accuracy of 97.88%, a validation accuracy of 95%, a testing accuracy of 100%, and a loss of 4.93%.

Abstract

A security system is needed to prevent theft or other criminal acts. One of the implementations of a popular security system today is the Smart Lock System. This study discusses the design of an intelligent lock system using QR Code scanning as a locker key at the Library of the Faculty of Engineering, Universitas Riau. The design of the device system consists of one piece of ESP8266 Node MCU module, one piece of 12V Power Switch Adapter, one piece of AMS 1117 module with 3.3V and 5V output voltages, three pieces of 5V Relays, three pieces of 12V Solenoids. The security system has been improved compared with existing security systems, such as verification for personal data, email notification, and level login to get theft to treat notification. This paper also measured the delay of the device system. Based on measurement results, the average delay obtained is 1.66 seconds.

Abstract

The performance of a three-layer metal gasket is affected by the contact width between the gasket surface and the rough flanges. In the simulation, proper flange roughness modeling will make it easier to predict the gasket performance later. The surface roughness modeling in the simulation will be compared with experimental measurements to determine how much contact occurs due to the rough flange surface. Experimental measurement of real contact width using a digital microscope and simulation using finite element software. The measurements between the simulation results of the real surface roughness model and the experimental results show that they are close to the same. So it can be said that our simulation model is close to the actual conditions.

Abstract

This study discusses the design of a hydrogen-hydrogen-oxygen (HHO) based welding tool, which uses the concept of water electrolysis through a dry cell generator. To determine the optimal design of the HHO dry cell generator, a design experiment was carried out using the Taguchi method by taking into account several parameters, namely the configuration of the electrode plate, the duty cycle Pulse Width Modulation (PWM), the type of catalyst, the electrolyte concentration, and the thickness of the gasket of the electrode plate. Each parameter is varied in 4 levels so that 16 kinds of experiments are obtained with an orthogonal array. In addition, the Combustion temperature data was collected after determining the optimal design. The experimental results show that this HHO-based welding tool is able to produce an average temperature reach of 1063.85 °C.

Abstract

The availability of non-renewable energy has recently been running low and so impacts electrical energy. Renewable energy is converted from natural sources to kinetic energy. The Double Propeller Water Turbine is a water turbine that is suitable to be applied using a small flow head. This research is a development of previous research by changing the degree of inclination of the blade angle on the turbine, which is used to determine changes in the power and efficiency of the Double Propeller turbine at various speeds. The results showed that the Double Propeller turbine rotation’s performance was directly proportional to the slope of the turbine blade angle. The optimum angle of attack on the hydro turbine affected the lift force and the ability of the water flow to capture water power. At the lowest blade angle, which is 20 degrees, the highest rotational speed is obtained with a value of 335 rpm. The turbine generates the most significant power with a blade angle of 20o, with a value of 4.81 watts, and the highest efficiency is 24%. The degree of blade angle affects the performance of the Double Propeller turbine.
