Pengaruh Faktor Lingkungan terhadap Strategi dan Kinerja Industri Manufaktur di Jawa Timur

This research examined the influence of environment factors (industrial, operational and remote) on the strategy and performance of manufacturing industries in East Java. The Structural Equation Modeling (SEM) was employed to test the hypotheses which emerged from the observed conditions. Moreover, the AMOS 4.0 was also used to perform the SEM. The results showed that the environment factors, i.e. industrial and operational environments as well as remote environments jointly affect the understanding of the environment industry matching with industry and environmental operational environment to establish its strategic objectives as an effort to achieve optimum performance manufacturing industries in East Java. Industrial environment conditions cannot be isolated from the global crisis because most industries prefer to concentric diversification strategy where new product technologies have a relevance to existing products

Identifikasi Plant Purwarupa Heat Exhcanger Tipe Shell dan Tube Model Counter Flow Memanfaatkan Software Matlab

– a heat exchanger is a device that acts as a transfer of heat energy between two fluids or more. There are various ways to improve the effectiveness of heat exchange devices, according to mechanical engineering, by increasing the convection heat transfer coefficient, increasing the surface area of the heat exchanger and increase the temperature difference to reach the specified temperature. The heat transfer can be defined as the transfer of energy from one system to another as a result of the temperature difference, this energy transfer always occurs from a high temperature system to another lower temperature system and will stop after the two systems reach the same temperature, the temperature difference is the main requirement for the transfer of the system.

Implementation of Automatic DC Motor Braking PID Control System on (Disc Brakes)

The vital role of an automated braking system in ensuring the safety of motorized vehicles and their passengers cannot be overstated. It simplifies the braking process during driving, enhancing control and reducing the chances of accidents. This study is centered on the design of an automatic braking device for DC motors utilizing disc brakes. The instrument employed in this study was designed to accelerate the vehicle in two primary scenarios - before the collision with an obstacle and upon crossing the safety threshold. It achieves this by implementing the Proportional Integral Derivative (PID) control method. A significant part of this system comprises ultrasonic sensors, used for detecting the distance to obstructions, and rotary encoder sensors, which are utilized to measure the motor's rotational speed. These distance and speed readings serve as essential reference points for the braking process. The system is engineered to initiate braking when the distance value equals or falls below 60cm or when the speed surpasses 8000rpm. During such events, the disc brake is activated to reduce the motor's rotary motion. The suppression of the disc brake lever is executed pneumatically, informed by the sensor readings. Applying the PID method to the automatic braking system improved braking outcomes compared to a system without the PID method. This was proven by more effective braking results when the sensors detected specific distance and speed values. Numerous PID tuning tests achieved optimal results with K_p = 5, K_i = 1, and K_d = 3. These values can be integrated into automatic braking systems for improved performance. The PID method yielded more responsive braking outcomes when applied in distance testing. On the contrary, the braking results were largely unchanged in the absence of PID. Regarding speed testing, the PID method significantly improved the slowing down of the motor speed when it exceeded the maximum speed limit of 8000 rpm. This eliminates the possibility of sudden braking, thus maintaining the system within a safe threshold. The average time taken by the system to apply braking was 01.09 seconds, an indication of its quick responsiveness. This research is a valuable addition to control science, applying the PID control method to automatic DC motor braking. It provides valuable insights and concrete applications of PID control to complex mechatronic systems. It is also noteworthy for its development and optimization of suitable PID parameters to achieve responsive and stable braking. The study, therefore, offers a profound understanding of how PID control can be employed to manage braking systems on automatic DC motors, thereby advancing knowledge and application of control in control science and mechatronics

Test Equipment Adding Electric Supercharger on Injection Machine for Biofuel Optimization

One of the problems that occur in our earth is air pollution and the depletion of fossil fuel stocks. Researchers want to make research on how the fuel burns completely, so that the resulting exhaust gas is environmentally friendly. In addition, this research is expected as an education and comparison before and after the turbofan is given. This study will control the AFR (Air Fuel Ratio) in the intake air to get the right ratio of fuel to air stoichiometry. By controlling the air intake into the engine and adding a turbofan using the PID method. The way the turbofan works is using the lamba sensor as system input, then the value of the lamba sensor is entered into the PID method. From the PID value will determine the speed of the brushless motor which aims to get the best AFR. By looking at the lambda sensor output which is close to the setpoint of 0.5, it is expected to produce a more perfect mixture of air and gasoline
