Abstract

The rescheduling due to delays in the repair project of two ships being worked on simultaneously was carried out using the Critical Path Method (CPM) and Time Cost Trade Off (TCTO). The data obtained came from the repair lists of each ship. The aim was to expedite project completion and achieve the most optimal time and cost efficiency. Acceleration alternatives were calculated, such as adding labor and extending work hours on the critical path. The acceleration steps included adding 2 and 4 extra working hours and increasing the number of workers. The analysis results showed that the most optimal time reduction was achieved by adding 4 hours of overtime and 21 additional workers, successfully reducing the project duration from 55 days to 20 days, with a time efficiency of 64% and a cost savings from Rp 393,300,000 to Rp 390,330,000, a savings of Rp 2,970,000 or around 0.7%. The daily productivity for scrapping work reached a maximum of 650 m²/day, while the increase in labor and 2 extra working hours resulted in 780 m²/day, and 4 extra working hours resulted in 845 m²/day.

Abstract

In the process of creating various types of plastic, several tools are required to support the development process. In this regard, Politeknik Industri ATMI has attempted to develop a supporting tool for mixing plastic ore. The objective of this research is to design, build, and test an efficient and economical mixing machine for processing plastic ore on a small scale. To create this tool, the author used observation and design realization methods. After a lengthy process, a plastic ore mixing machine with a capacity of 20 grams was produced. This paper discusses the plastic ore mixing machine designed for use in testing laboratories. This mixing machine is a device used to process plastic ore into new types. In this study, the author developed a plastic ore mixing machine with a volume capacity of 20 grams. This machine is used to combine two or more types of plastic ore, aiming to produce high-quality plastic. To achieve this, the machine was developed using two mixing shafts and a melting system with heating elements. Additionally, the mixing process chamber was designed with two compartments, corresponding to the positions of the mixing shafts. This design is expected to maximize the mixing process of each type of plastic, resulting in a homogeneous plastic product.

Abstract

Global warming has changed weather patterns in Indonesia, making it difficult to predict, and often the weather changes rapidly, such as sudden rain when the weather is hot. This study aims to overcome the problem of sudden weather changes by using a set of tools that can monitor humidity and wind speed based on the Internet of Things (IoT). This system uses an ESP32 microcontroller combined with a DHT22 sensor to measure humidity and an anemometer to measure wind speed. The collected data will be processed to produce an analysis of weather conditions using the fuzzy logic method and stored in Firebase for efficient data management. In addition, the user interface is designed based on Android Studio to facilitate real-time monitoring. The results of the study show that the developed system is able to provide accurate and reliable weather information, thus helping people plan their activities better.

Abstract

This paper provides a detailed investigation into the effects of Trioctyl Trimellitate (TOTM) plasticizer levels on the hardness of Polyvinyl Chloride (PVC) materials. The study reveals an inverse correlation between the level of TOTM plasticizer and the hardness of PVC, with an increase in TOTM levels leading to a decrease in hardness. This trend is consistent across various PVC samples, despite minor variations. The role of plasticizers in determining the physical and mechanical properties of PVC is further explored, emphasizing their function in reducing PVC's crystallinity, thereby producing a clearer and more flexible material. This research contributes to the understanding of how plasticizers can be used to tailor the properties of PVC, leading to the development of two distinct types of PVC: Flexible PVC, which contains a plasticizer, and Rigid PVC, which does not. The findings underscore the importance of plasticizers in material design and engineering, offering valuable insights for future applications.

Abstract

In the fabrication industry, the welding process plays a crucial role in both engineering and repair production processes. Continuous use of welding machines can lead to a decline in their effectiveness. Suboptimal machines may produce low-quality products. A common issue encountered is the poor quality of welds, even when each step has been aligned with the Welding Procedure Specification (WPS). One source of this problem is the welding equipment itself. The objective of this study is to calibrate arc welding equipment to ensure it remains within machine standards. Calibration is performed in accordance with BS EN 50504:2008 and BS 7570:2000. The calibration focuses on measuring constant voltage and wire feed speed (WFS). The measurement results for WFS variation indicate that it does not exceed a 10% error margin. This suggests that the WFS complies with the established standards. Consequently, the Lincoln LN-25X wire feeder speed is ready for use in fabrication and production processes.

Abstract

Brago Luchttechniek BV is a company specializing in the production of PIR (Polyisocyanurate) air ducts, facing challenges in maintaining accuracy and consistency in the polyester insulation spraying process on its products using Kawasaki collaborative robots (cobot) for automation. To address these challenges, this study designed a web-based Human Machine Interface (HMI) to automate the polyester insulation spraying process on PIR air ducts using the Kawasaki Cobot. A web-based HMI was chosen for its ease of development, flexibility, and integration capabilities with modern technology. This HMI uses the TCP/IP protocol to send real-time command signals to automation devices such as the Kawasaki Cobot and devices connected to the Programmable Logic Controller (PLC). Testing results demonstrated an improvement in the spraying process efficiency, reducing the time from 15"“18 minutes conventionally to 5"“7 minutes with the web-based HMI automation. Additionally, the web-based HMI successfully communicated with other devices connected to the robot, such as the conveyor belt and rotating table, via TCP/IP protocols, with each device having its own ID and IP address to facilitate linear message delivery, prevent collisions, and minimize errors. After eight successful automation tests on four different products, the system operated smoothly and systematically through the available HMI controls. The system was also evaluated by four respondents, with an overall score of 4.33 out of 5, indicating a high level of satisfaction.

Abstract

This research aims to develop a Procedure Qualification Record (PQR) for Repair Through Thickness on S355 KT0 material using the GTAW method for the root, SAW for filler and capping. The welds were repaired using gouging and grinding before undergoing repair welding with the SMAW method. The study employed experimental methods with Non-Destructive and Destructive tests following AWS D1.1 and Client Specification MHK-COMP-SPE standards. The test results indicate defect-free welds that meet AWS D1.1 standards in terms of mechanical properties such as tensile strength, bending, impact, and hardness. The tensile strength values reached 609 MPa (longitudinal specimen) and 539 MPa and 540 MPa for transverse specimens. The lowest impact test value was 139J in the fusion line +2 mm repair to original welds area. The peak hardness test value was 240 VHN in the HAZ (repair to original weld) region. The test results were also used to formulate a PQR that aligns with specific requirements. This research is expected to provide guidance for performing repair welding on S355 KT0 material.

Abstract

This study aims to analyze the effect of machine availability on production output at PT XYZ. Data collection was conducted from January to March 2024, focusing on machine downtime, total operational hours, and weekly production output. The method used involves the calculation of Mean Time Between Failure (MTBF), Mean Time To Repair (MTTR), and availability, followed by a correlation analysis between availability and production output. The results show a strong correlation between availability and output, with a correlation value of 0.852. In Week 6 and Week 11, machine downtime caused availability to drop to 98.41% and 97.96%, respectively, which directly impacted production output. Based on these findings, it is recommended that PT XYZ improve preventive maintenance and minimize downtime to maintain optimal machine availability and maximize production output

Abstract

A pressure vessel is a container designed to hold fluids under pressure, including liquids and gases with varying pressures and temperatures. The pressure exerted on the vessel's walls and body is a critical factor that must be carefully considered to ensure compliance with applicable international design standards and prioritize worker safety and security. This research focused on a pressure vessel to investigate the impact of temperature on shell thickness to meet ASME standards. The study utilized shell components made from SA-516 Gr 70 and SA-537 materials. Experiments were conducted with each material at temperatures of 250°C, 235°C, and 343°C, revealing that thickness varies based on material and temperature. The research findings demonstrate compliance with ASME standards, as the shell thickness in all trials exceeded the minimum specified in the drawings.
