Abstract

The utilization of vibration energy from a 4-stroke engine as a potential source of electrical energy. Previous studies have focused on analyzing the vibration characteristics and frequency response functions of the 4-stroke engine, but there is a lack of research on harnessing vibration energy as a source of electrical energy. Therefore, this research aims to fill this gap by developing a system to harness the vibration energy from the 4-stroke engine, making it a primary focus of the study. The method employed is an experimental study involving data collection using an FFT Analyzer and Matlab. The research results indicate the presence of several mode shapes in the 4-stroke piston motor. The energy harvesting device utilized is of the electromagnetic type. However, the research reveals that the utilization of vibrations from the 4-stroke piston motor as a source of electrical energy is still not efficient and requires further development. There are various mode shapes in the 4-stroke piston motor at different rotational speeds, but the electromagnetic energy harvesting device used is unable to generate significant electrical energy. Therefore, this research provides a foundation for conducting further research in utilizing the vibrations of a 4-stroke piston motor as a more efficient source of electrical energy

Abstract

An apparatus for venting or perforating green tires in order to release trapped air is known as a-venting machine. Productivity will drop in May and July of 2023 as a result of scrap issues brought on by green tire defect creases. The term "defect crease" refers to a flaw in which the operator's manual hand rotation causes silicon to adhere to the side or tread ending of the green tire. Modifications were made with the intention of reducing scrap brought on by defect creases in order to lessen this issue. In order to eliminate the need for the operator to manually rotate the green tire, the roll driver that was initially fixed was replaced with one that can rotate automatically. The scrap defect decrease was 93.15% lower as a result of the modification, going from 73 ppm in the May–July 2023 period to 5 ppm in the September–November 2023 period

Abstract

Milling machines are machines used in the production process. The time required during the machining process must be more efficient in order to obtain the desired production capacity. The aim of this paper is to utilize vibrations originating from milling machines in industry as a source of Harvesting Energy Vibration. The research was carried out by varying the feeding depth of the milling machine so that it could be seen how much stress was produced. The Lushan Model ZX32 milling machine was used in this research, where vibrations from the vibration source were measured using an FFT Analyzer connected to an Accelerometer Sensor and Harvesting energy vibration connected to an Oscilloscope. Meanwhile, the workpieces used in this research were Aluminum 5052 and PVC. The results of the research were that on PVC material with an ingestion depth of 1 mm, the vibration frequency at 210 rpm was 71 Hz, the amplitude was 1.38 mm/s2, resulting in a harvesting energy of 6.449 mV. And the results of research using aluminum at 210 rpm rotation with a feeding depth of 3 mm obtained a vibration frequency of 90 Hz with an amplitude of 1.508 mm/s2 producing a harvesting energy of 5.856 mV. The research results show that the PVC material produces higher harvesting energy vibration at a depth of 1 mm, and the aluminum material produces higher harvesting energy vibration at a depth of 3 mm

Abstract

In order to better understand the phenomenon of applying GEC reinforcement to RCC based on the percentage of surface crack pattern (PCP), this research will use e-glass epoxy composite laminate (GEC) to obtain the damage pattern of reinforced concrete column specimens (RCC) utilizing GEC. Additionally, it will compare the splitting tensile strength (STS) and SCP. In accordance with ASTM C496 guidelines, the RCC specimens used in this investigation had a cylindrical shape and measured 150 mm in length and 50 mm in diameter. GEC material, consisting of 0–4 layers of woven e-glass fiber sheets, was applied as an extra layer on top of the RCC. In compliance with ASTM C496 guidelines, a Universal Testing Machine (UTM) was used to perform the split tensile test. With the aid of Adobe Photoshop software, the Histogram approach was used to calculate the crack pattern's proportion. The study's findings demonstrated that the specimens reinforced with four layers of GEC exhibited the highest damage pattern. This suggests that the reinforced specimens must be subjected to a sizable load in order to be damaged. Hence, the damage that occurs in the specimens can be lessened by applying GEC layers on RCC. Further information about the performance of RCC reinforced with GEC is also provided by a comparison of the splitting tensile strength and the percentage of fracture pattern

Abstract

The Banburyy mixer machine is a tool used to mix materials, such as raw rubber, carbon and chemicals into a homogeneous mixture. The Banburyy engine component consists of a rotor. The rotor rotates as a result of the power transmission coming from the industrial motor, the power transmission uses a gearbox. Therefore, induction motors play an important role in Banbury engines. If damage to the induction motor is not detected early, it can result in more severe damage or even unusability. Therefore, in this paper we will analyze the characteristics of bearing damage using the Fast Fourier Transform (FFT) method and the Hilbert method on mixer motors. The bearings used in the mixer motor are SKF 6330/C3 bearings in the drive end position and SKF 6324 types in the non-drive end motor position. The measurement results were then processed using the Fast Fourier Transform (FFT) and Hilbert Transform methods. The rotation speed variations carried out in the test were 500 rpm, 1000 rpm and 1500 rpm. Bearing damage analysis uses a vibration method that is obtained based on characteristic frequency values that indicate the occurrence of damage, in the form of Ball Spin Frequency (BSF) on the ball, Ball Pass Frequency Outer (BPFO) on the outer track, Fundamental Train Frequency (FTF) that occurs on the cage, and Ball Pass Frequency Inner (BPFI) on the inner track, according to bearing specifications and motor shaft rotational speed. From the analysis results, it was found that in the SKF 6330/C3 bearing an amplitude appeared at a frequency close to the FTF value of 7.031 Hz along with its harmonic frequencies, whereas in the SKF 6324 bearing no frequency of damage appeared. This indicates that the bearing in the drive end position, namely the SKF 6330/C3 bearing, is thought to have experienced damage to the cage bearing (ball bearing cage). The action taken is to replace the bearing with a new one as soon as possible

Abstract

A hydroelectric power plant (PLTA) uses the flow of water as a source of energy. Evaluating the output of hydropower facilities, including the optimal height of the waterfall, turbine torque, electrical power, generator power, and generated efficiency, was the aim of the study. This study intends to investigate the power, torque, and efficiency that may be produced by a hydroelectric power plant with a whirlpool-type turbine, as well as how the height of falling water influences the operation of the plant. The experiment in this study measures three different waterfall heights with five different blade configurations. The study on the hydropower prototype involved three trials that collected data on torque, power, efficiency, waterfall height, and water discharge. The PLTA Prototype's best potential head in Test 3 was determined to be 0.01143, with a height of 0.67 meters, no sluice, and a diameter of 0.0625 meters. The lowest water outflow was discovered at a head of 0.55 meters with a water debit of 0.01036. The third attempt, which featured a sluice opening with a diameter of 0.0625 meters and a height of 0.67 meters (head), used the most water power in the experiment. The testing yielded the following results: 75.13 watts of water power, 5.16 watts of generator power, 0.233 N.m. of torque, 2.63 watts of turbine power with a generator load 3.73 watts without one, and 6.87% efficiency. Data gathered from the hydropower prototype's operation can be used to construct testing instruments for use in laboratories

Abstract

Pothil is a common regional dish from the Magelang region prepared with cassava. The peeling and frying of the cassava is the first step in the process of manufacturing pothil. People still utilize manual cooking oil drainers during the pothil frying process, which makes them ineffective at draining the oil. Using a dynamo, which is a device that transforms mechanical energy into electrical energy, one can create a basic spinner machine to assist with oil draining. The purpose of this study is to evaluate the efficiency of a basic spinner machine for draining oil from pots and to ascertain the correlation between rotation duration and oil production volume. This study used a quantitative experimental design, where oil volume was the dependent variable and rotation duration was the independent variable. An efficacy test utilizing oil paper to view the oil beams on the pothil was used to gauge how efficient utilizing a spinner machine would be. The study's findings indicate that when compared to turning the spinner machine for one or two minutes, a spinner machine that is rotated for three minutes can create the most oil—21 milliliters. Consequently, the longer the spinning period, the more oil is generated and the more successful the spinner machine is in lowering the oil content of the pothil

Abstract

Every company, including PT, has goals they'd like to accomplish. One of the businesses in the two-piece can sector is CPC. Up until now, PT's goal has been to switch products. The CPC is still not fulfilled; specifically, from January 2022 to May 2023, the product replacement time is still 42 minutes, resulting in the waste of 1043 cans, although the objective was set at 30 minutes for the replacement of the product and 800 cans for spoiling (wasted cans). The current issue is that 800 cans are wasted, and the goal product replacement time is 30 minutes. A quality control group was employed in this study's methodology (Pareto and fishbone diagrams). The primary goal of this study is to identify the underlying cause of the 42-minute product replacement time and the wasted 1043 cans. The analysis's findings demonstrated that the issue of resetting the plate is the one that frequently arises while switching out products. Several underlying causes of the reset plate issue were discovered after additional investigation, one of which was the unclear marking on the plate, which led to imprecise results when the plate was installed on the cylinder. Damages the can printing and necessitates a second plate installation, which wastes time and leads to spoilage. Consequently, a repair plan was created and put into action by changing the plate's markings to make installation easier to understand. This led to a quicker process of replacing the product (41 minutes before repair, 32 minutes after repair), as well as a decrease in the number of wasted cans (850 cans before repair, 828 cans after repair).

Abstract

Robots are one of the technologies that is currently advancing quickly. Generally speaking, a robot's movement is similar to that of an automobile; it can only move forward, backward, left, and right. Because the movement is controlled by these movements, it is thought that the robot's movement is extremely restricted to the left and right directions. solely with the front wheels. As a result, a robot was developed in this study that can control sliding motions to the left and right utilizing omniwheels on its front and back wheels. Badminton is a sport involving rackets that is played by two people or two opposing pairs. Robotic badminton players are employed as a substitute for human trainers in the training process, particularly for service and drive motions. With the use of a wireless joystick, the robot's ATMega 8535 microprocessor controls both the robot's direction of motion and the movement of its racket. Using a double acting pneumatic cylinder that requires 7 bar of air pressure, the robot service arm uses the compressor's air pressure. The average time it takes for the racket to strike the ball at 7 bar of wind pressure is 00:5.2 seconds. The time it takes for the ball to fall onto the racket in the absence of wind pressure is 00:28 seconds on average. A difference value of 00:22.7 seconds is acquired, and this value will be utilized as the programming reference delay. The robot encounters a slope with an average angle change of 7º when moving forward, an average angle change of 10º when moving backward, an average angle change of 5.2º when moving right, and an average angle change of 3º when moving left. The uneven field surface causes the robot to move at a slope, which modifies the speed of the motor on the wheels
