Abstract

Machine maintenance is an important factor in supporting a manufacturing process that is competitive in the market. Therefore, every company must carry out regular machine maintenance to ensure the machine operates optimally. The aim of this research is to identify damage that may occur to the pump engine and analyze pump maintenance costs which include the cost of repairing or replacing components. The method used in this research is the Life Cycle Cost (LCC) method. The research results show that the maintenance interval for each Bearing component is 1044 hours, Shaft 64 hours, Impeller 76 hours, Gasket 91 hours, Rotor 103 hours, and Bearing Housing 110 hours. The optimal total cost usage at the age of 3 years is IDR. 3,129,542,106/year with the optimal number of mechanics, namely 3 people, previously there were 5 people.

Abstract

In the current industrial era, operational efficiency is key for companies. Machining service providers can be seen from the number of workshops. At CV. XYZ has a lathe problem, there is no method for maintenance. Therefore, the purpose of this study is to calculate machine maintenance in companies using the Autonomous Maintenance (AM) method. From the calculation results obtained during January-June 2024, the highest average OEE value was in May 88.82%, Availability Rate parameters 88.76%, Performance Rate 99.28%, Rate of Quality 100%. The lowest average OEE value occurred in January 52.11% with Availability Rate parameters 76.44%, Performance Rate 90.66%, Rate of Quality 75%. From these results, it is necessary to have machine maintenance with indications for each component: cleaning the dynamo regularly, ensuring the on-off button is connected which is expected to increase effectiveness, extend machine life, and reduce maintenance costs.

Abstract

The construction industry is growing fast and increasing the demand for concrete which requires sustainable materials. Concrete is weak in tension and needs fiber reinforcement to improve strength. This study explores lathe waste steel fibers as a sustainable option to enhance tensile properties. Local industries produce large amounts of lathe waste that can be used in fiber-reinforced concrete. Traditional destructive testing is expensive and slow because it needs heavy machinery like Universal Testing Machines. This research combines destructive and computational analysis using ANSYS 15 for finite element modeling. Cylindrical and beam specimens were tested with fiber ratios from 0 to 3 percent. Results show that 2.5 percent fiber content gives the best compressive and flexural strength. Scanning electron microscopy confirms stronger bonding as fibers break within the matrix instead of pulling out. This study proves lathe waste steel fibers improve both performance and sustainability in construction

Abstract

Formwork systems are essential for achieving efficiency and sustainability in multi-story construction. This study compares the cost and time efficiency of multiplex and aluminum formwork systems for constructing beams and slabs on the 6th to 13th floors. Field observations and a literature review were employed to gather data using a mixed-methods approach. This study adopts a mixed-methods approach, combining quantitative and qualitative methods. The findings reveal that aluminum formwork requires 60 days to complete, compared to 112 days for multiplex formwork, saving 52 days. Regarding cost, aluminum formwork amounts to IDR 1,805,910,198, offering savings of IDR 159,540,423 compared to multiplex formwork at IDR 1,965,450,621. Graphical analysis highlights the advantages of aluminum formwork in optimizing project workflows and reducing delays. These results demonstrate aluminum formwork potential to enhance efficiency, minimize material waste, and support sustainable construction practices. Future research is encouraged to explore alternative materials and labor strategies to further advance sustainability in the construction industry.

Abstract

This study analyzes the productivity of tower cranes in high-rise building construction projects in Indonesia, focusing on sustainable practices and advanced techniques. The rapid growth of infrastructure has heightened competition in the construction sector, making efficiency essential. Tower cranes are key to accelerating project timelines and reducing costs, but their productivity can differ between theoretical specifications and actual field conditions. Using a quantitative descriptive method, this study compares theoretical productivity based on equipment specifications with direct field observations of the Potain MCT 205 tower crane at a high-rise site. Data on cycle time and lifting volume for work such as column reinforcement and concrete pouring were collected. Results show that theoretical productivity is higher than field observations, with a 40% increase for works and up to a 92% increase per phase. The findings stress the importance of incorporating advanced planning and sustainable practices to optimize productivity, minimize delays, and reduce costs in construction projects

Abstract

This research aims to develop an Android-based educational game that can increase students' understanding of the concept of solving. The development method used is the Multimedia Development Life Cycle (MDLC) with a heuristic approach. This heuristic approach involves a user-oriented design process, prioritizing ease of use and compatibility with scouting materials. This game is designed with an attractive and interactive appearance, and is equipped with games that are tailored to students' abilities. The trial results show that this educational game is effective in increasing students' understanding of the concept of fractions. A part from that, students also gave positive responses to the use of games as a learning medium. This year's Scout extracurricular is indeed a non-compulsory extracurricular but schools are obliged to organize scout extracurricular activities, in the current digital era, learning media applications and educational games are really needed in schools from elementary school to high school. Therefore, this research aims to apply the basics of scouting by using articulate storyline 3 software as a learning medium for students and can be implemented during the activity.

Abstract

This research examines the performance of various compressed sensing matrix techniques, with a focus on Principal Component Analysis (PCA) compared to conventional methods. By applying these techniques to a range of high-dimensional datasets, we assess their effectiveness in reducing data dimensionality while preserving essential information. Our results demonstrate that PCA consistently outperforms traditional methods in terms of both accuracy and computational efficiency. These findings have significant implications for fields such as signal processing, image compression, and data analytics, where efficient data representation is critical. The study provides a framework for selecting the optimal dimensionality reduction technique, enabling improvements in processing speed and accuracy in practical applications.
