Abstract

The car door is a vital component of an automobile, playing a key role in passenger safety during accidents. For an energy-saving competition, the strength of a car prototype's door was thoroughly examined using Finite Element Analysis (FEA). This study involved three testing methods: pole side impact, side impact, and door slam tests. Simulations were conducted using the Finite Element Method (FEM) with aluminum alloy 6061-T4, type-E fiberglass, and type-S fiberglass as materials. These materials were selected based on their stress properties, mass, and cost. The simulation indicated that the side impact test produced the highest stress levels, especially in the fiberglass materials. While the aluminum alloy exhibited higher von Mises stress than its tensile strength in one case, both types of fiberglass maintained safety as their tensile strengths exceeded the maximum von Mises stress. The pole side impact test showed aluminum's highest stress and deformation, whereas fiberglass materials showed higher stress and deformation in the side impact test. The door slam test demonstrated minimal stress and deformation across all materials. Among the three, type-E fiberglass demonstrated the most favorable and safest performance. Consequently, type-E fiberglass is highly recommended as the ideal material for the car prototype's door.

Abstract

This study discusses the effectiveness of the Kalix Plastik 501 Filling machine at PT. XYZ with the Total Productive Maintenance (TPM) approach, namely by examining the Six Big Losses factors on the machine to increase the Overall Equipment Effectiveness (OEE) value. The TPM program aims to produce effectiveness in all production by participating in productive, proactive and planned activities. TPM effectiveness can be done by measuring the OEE value, where the performance of a machine can be said to be optimal if it has an OEE international standard value of > 85%. This paper provides valuable information about the performance of production machines and offers possible solutions to increase their efficiency. Based on the results of data calculations, it is known that the average value of the effectiveness of the Kalix Plastic 501 filling machine at PT. XYZ is 57,05%, meaning that this value is below the standard OEE value. Furthermore, it is known that the losses that cause low OEE values in this study are the result of deceleration loss (23%), setup and adjustment (14,78%), idle and minor stoppages (7,41%), breakdown failure (3,91%), scrap loss (0.24%), and yield loss (0%). The six losses occurred due to human factors such as lack of manpower and not following work instructions, machine factors such as sensor errors, broken filling valves, and procedural factors such as lack of PM schedules and product operations not continuing.

Abstract

PT Aerofood Indonesia is an entity operating in the aviation logistics industry, specifically as a partner of the Garuda Indonesia airline.  The main problem faced is the tendency to have excessive supplies of raw materials, especially in the aspect of purchasing fruit because it is susceptible to damage. This phenomenon often recurs and peaks beyond dry goods capacity limits, especially the availability of papaya fruit which often exceeds capacity by more than 50%. Therefore, this research aims to identify the optimal forecasting method for papaya fruit to overcome the problem of excessive stock. In this research, four forecasting approaches were tested, namely Trend Analysis, Single Average Exponential, Double Average Exponential, and Holt's Winter Method. Forecasting calculations were carried out using a manual approach and supported by Minitab 18 software. The research results showed that the Holt's Winter method with a multiplicative approach produced the lowest Mean Absolute Percentage Error (MAPE), namely 16%.  The Holt's Winter method with a multiplicative approach has proven to be effective in producing accurate forecasts. By implementing this recommended forecasting method, it is hoped that companies can be more efficient in managing inventory and reduce the impact of losses due to excess stock.

Abstract

Robotics is one area where biomimetics, a field devoted to mimicking natural systems to address difficult human problems, has made great strides. Precise force measurement and analysis are vital to this field because they are necessary to reproduce and comprehend natural phenomena. This study addresses the challenge of accurate force measurement by developing a load cell-based device. It specifically assesses the impact of the taring process on measurement accuracy. The Weighted Least Squares (WLS) method is employed to thoroughly quantify the uncertainty of the device, ensuring reliability. The findings suggest that the single-input taring process contributes to variations in standard deviation, with accuracy peaking near the tared value and decreasing as the mass deviates from it. The linear calibration equation derived from WLS showed minimal variation in estimated mass values, with uncertainties ua = 2 10-6 and ub = 8 10-4. However, the expanded uncertainty increased with the input mass, largely due to the inherent uncertainty of the mass balance. Despite this, the hysteresis of the system was negligible, and its sensitivity of 0.01 N/g made it suitable for detecting small force fluctuations in biomimetic models. The study concludes that while the relative value of the maximum combined uncertainty, ULc = ±0.2% FSS, exceeds the reference specifications of the load cell, it remains adequate for applications requiring moderate precision. Future research will reduce mass balance uncertainty and consider environmental factors, thereby improving system effectiveness in biomimetic research.

Abstract

Changes in generator power losses are adjusted to the load needs in the field, which is constantly changing and can affect the value of the per- phase current and generator field current, causing power losses. The resulting power losses affect the efficiency of the PLTU generator. To determine the generator’s efficiency due to load changes, this study was carried out using manual calculation method by collecting data on specifications, resistance, and dialy log sheets of the 2x3 MW Malinau PLTU generator unit 2 conducted at PT. Nusa Daya Unit PLTU Malinau. Based on the callculation data on May 17, the highest efficiency was 79,69% at a load 2,372 MW, while the lowest efficiency was 78,03% at a load of 2,137 MW. For the callculation results of May 18, the highets efficiency was 79,51% at a load 2,342 MW, while the lowest efficiency was 76,37% at a load of 1,941 MW. The greater the power generated by generator, the higher the efficiency of the generator and the better the generator performance. Keywords: PLTU, generator, load changes, power losses, efficiency

Abstract

The Dahlander motor is an asynchronous AC motor that operates at two or more distinct rotational speeds, making it different from standard three-phase motors, which generally maintain a single speed under the same power conditions. This motor features a squirrel-cage rotor design and is integrated with a programmable logic controller (PLC), which simplifies wiring systems and allows operational adjustments without altering the wiring layout. However, an additional component, the selector switch, is also employed. This switch controls the motor's rotational direction, enabling it to rotate either clockwise or counterclockwise. The study utilizes a quantitative approach with a developmental design to assess the performance of the Dahlander motor control system. The system functioned as expected, with the selector switch responsible for changing rotational direction. In the right position, pressing the ON 1 button activates contactor 1 for slow clockwise rotation, while pressing ON 2 activates contactors 2 and 3 for fast clockwise rotation. In the left position, pressing ON 1 activates contactor 4 for slow counterclockwise rotation, and pressing ON 2 activates contactors 5 and 6 for fast counterclockwise rotation. The measured rotational speeds were as follows: during slow clockwise rotation, the rotor reached 1494 rpm, while for fast clockwise rotation, it hit 3055 rpm. During slow counterclockwise rotation, the rotor speed was 1456 rpm, and for fast counterclockwise rotation, it reached 3050 rpm.

Abstract

The Refrigerant Accumulator equipment is a pressure vessel located within the production system unit, namely the Dew Point Control (DPC) Unit. The Refrigerant Accumulator is a crucial component within the DPC Unit as it serves as a reservoir for the Propane refrigerant liquid. In case of a failure of this equipment, it would halt the entire process in the DPC Unit and impact the control of gas dew point that is transmitted to consumers through pipelines. Hence, a more effective method is required to prevent failures in the Refrigerant Accumulator. One of the methods that can assist in more effective inspection is Risk-Based Inspection (RBI). Risk-Based Inspection is a risk-based inspection methodology, where the main output obtained is an inspection plan determined based on the risk of the equipment. It prioritizes inspections for equipment with higher risk of damage, thus optimizing equipment maintenance and aiding companies in establishing effective maintenance strategies. Therefore, this study aims to analyze the risk level of the Refrigerant Accumulator equipment using the Risk-Based Inspection method according to API 581, determine the risk level of the Refrigerant Accumulator equipment, and provide appropriate inspection planning recommendations for the Refrigerant Accumulator equipment. Based on the results of this study, the Risk-Based Inspection analysis yielded values for Probability of Failure (PoF), Area-based Consequence (CA), and Financial Consequence (FC) through quantitative calculations based on the steps outlined in API 581. The PoF value is 5.011×10-6, the CA value is 3,316.36 ft2, and the FC value is $22,746,756.91. From the analysis results, the risk level of the Refrigerant Accumulator equipment is categorized as Medium-Risk, with a Probability of Failure of 5.011×10-6 in category 1 and a Consequence of Failure of $22,746,756.91 in category E. Consequently, the final category is 1E, with a remaining life of 33.7 years. Based on the obtained risk level, the recommended inspection planning is to conduct the next inspection on December 2031, using Visual Inspection method with 100% surface coverage and Phased Array Ultrasonic Testing (PAUT) with 90% surface coverage.
